The invention generally relates to network-enabled bicycles, bicycles configured for interconnecting with one another to form a mesh network, electronic devices for bicycles and related methods.
Cyclists often desire access to a range of information while they are riding, prior to their ride or afterwards. Such information may include speed, position, elevation, inclination, traffic updates, route suggestions, road surface conditions, cycling lanes, information relating to a planned route, previous routes taken and related information to the previous routes taken, and various other information that may be relevant to a cyclist's riding experience.
Existing solutions for providing a cyclist with a range of cycling related information can be costly and/or typically require the cyclist to attach various sensors to his or her bicycle frame and/or to various components of the bicycle, such that these various sensors can communicates with an external electronic device, such as for example a smart phone. The process of attaching sensors can be tedious and time consuming. In addition, the external electronic device may need to be physically connected and disconnected from the sensors when the bicycle is unattended to prevent theft of the external electronic device.
Another issue of concern for users of bicycles pertains to bike theft. Existing anti-theft devices for bicycles have generally been limited to physically locking a bicycles frame and/or its components to bike racks, fences, street signs, parking meters, trees and other objects, and do not allow for a cyclist to easily view or track the current location of his or her bicycle.
Yet another issue of concern for users of bicycles pertains to shifting gears and particularly to automated and partially automated gear shifting. While there are some solutions for automatically shifting the gears of a bicycle, such solution tend to be generally limited to considering a cyclist's cadence (i.e., pedaling rate).
In light of the above, there is a need in the industry to provide devices and systems for use with bicycles that alleviate at least some of the deficiencies with existing solutions.

These and other aspects of the invention will now become apparent to those of ordinary skill in the art upon review of the following description of embodiments of the invention in conjunction with the accompanying drawings.
A detailed description of embodiments of the invention is provided below, by way of example only, with reference to the accompanying drawings, in which:
It is to be expressly understood that the description and drawings are only for the purpose of illustrating certain embodiments of the invention and are an aid for understanding. They are not intended to be a definition of the limits of the invention.
Although in this example four bicycles 1021 1022 1023 1024 and two wireless network access points 1041 1042 are shown, in alternative implementations the number of bicycles 102 may be more or less than four and the number of wireless network access points 104 may be more or less than two. Similarly, although only a single data network 106 and a single server 108 are illustrated, in alternative implementations the data network 106 may comprise more than one data network and the server 108 may comprise multiple servers in some practical implementation.
In a typical practical implementation, each bicycle 102 is equipped with a respective electronic device 300 having the hardware components configured for collecting metrics related to the usage of the bicycle 102, which may include amongst other position information associated with the bicycle 102. Each electronic device 300 also includes hardware components configured for allowing it to establish communication links with each one of the other electronic devices 300 and(or) with each of the wireless network access points 104 that in proximity (within range) of it.
For example, when electronic device 3003 (associated with bicycle 1023) is in range of electronic device 3001 (associated with bicycle 1021), the electronic device 3003 may detect electronic device 3001 and establish a connection with it using any suitable communication protocol so that an exchange of data may be performed between the two bicycles 1021 and 1023. In a specific implementation, the exchange of data between the two bicycles 1021 and 1023 may include for example metrics related to the usage of the respective bicycles 1021 and 1023. As a result of such an exchange of data, each one of electronic devices 3001 3003 may store information conveying metrics of both bicycles 1021 and 1023.
As indicated above, each of the electronic devices 300 includes hardware components that may also be configured for allowing it to establish communication links with each of the wireless network access points 104 that is in proximity (within range) of it. For example, when electronic device 3001 (associated with bicycle 1021) is in range of wireless network access point 1041, the electronic device 3001 may detect and establish a connection with wireless network access point 1041 using any suitable communication protocol so that an exchange of data may be performed between the electronic device 3001 and the server 108 (also referred to as a remote computing device) over network 106 via wireless network access point 1041. More specifically, the wireless network access point 1041 includes the required functionality for causing information provided by the wireless network access point 1041 to be routed over the data network 106 so that it reaches one or more specific network destinations, which in this specific example includes the server 108. In a specific implementation, the exchange of data between the bicycle 1021 and the server 108 may include for example metrics related to the usage of the bicycle 1021, and optionally metrics related to the usage of any of the other bicycles 1022 1023 depending on the information stored on electronic device 3001, being transmitted from electronic device 3001 to the server 108 via wireless network access point 1041. The exchange of data between the bicycle 1021 and server 108 may also include various data elements conveying contextual information that may be useful to either bicycles 1021 or to bicycles that may be in the general vicinity of bicycles 1021 being transmitted from the server 108 to electronic devices 3001. For example, such contextual information may include, without being limited to, road condition information, traffic pattern information, incline information, advertizing information or any other suitable type of information. As a result of such an exchange of data, electronic device 3001 may store information conveying contextual information provided from the server 108 and the server 108 may store metrics related to the usage of the bicycle 1021, and optionally metrics related to the usage of any of the other bicycles 1022 1023.
The network-enabled bicycles 102 interconnected to one another in an electronic network 100 of the type depicted in
Yet in another example, a fourth bicycle 1024 may directly communicate with the server 108 via a second wireless network access point 1042 and the first bicycle 1021 may directly communicate with the server 108 via the first wireless network access point 1041, which may allow the fourth bicycle 1024 and first bicycle 1021 to indirectly communicate with each other. As such, the wireless network access points 104 may extend a network of interconnected bicycles 1021 1022 1023 connected directly or indirectly to a first wireless network access point 1041 to a network of interconnected bicycles 1024 connected to a second wireless network access point 1042. It is appreciated that such a configuration may allow for indirectly connected bicycles to exchange data with each other and with the server 108 without there being a direct connection between each bicycle and the server 108. Moreover, it is possible for a bicycle to communicate information to the server 108 while the bicycle has not itself been connected to a network but merely had established a connection with another bicycle that it had come in the vicinity of while travelling. It is thus appreciated that such a configuration may allow for the bicycles 102 to communicate data amongst each other such that when one of the bicycles from the set of bicycles 102 enters in range of one of the wireless network access points 104, the previously communicated data is then communicated to the server 108. In other words, and as will be described in great detail later on in the present description, the configuration shown in
The specific network between second bicycle 1022, first bicycle 1021 and third bicycle 1023 can be implemented in some specific embodiments as a mesh (or mesh-type) network.
The bicycles 102, the electronic devices 300, the wireless network access points 104, the data network 106 and the server 108 is described in further detail later in this document and the functionality of each of the aforementioned components will likely become more readily apparent to the reader later on.
In other cases, the electronic device 300i may be compartmentalized or embedded within other parts of the frame 204 of the bicycle 102i, including but not limited to the head tube, fork, down tube, top tube, seat tube, chain stay, seat stay. In other case, the electronic device 300i may be compartmentalized or embedded within other parts of the bicycle 120i, including but not limited to the hub, shifter, brake leaver, pedal, seat, suspension, or any other suitable bicycle component.
It is appreciated that the compartmentalization of the electronic device 300i in the bicycle 120i may reduce the need of the cyclist to attach various sensors to his/her bicycle frame and/or to various components of the bicycle. It is also appreciated that the compartmentalization of the electronic device 300i in the bicycle 120i typically would not require the cyclist to disconnect the electronic device 300i from the bicycle 120i to prevent theft of the electronic device 300i. Still, it is also appreciated that the compartmentalization of the electronic device 300i in the bicycle 120i may render it more difficult for a thief to disconnect the electronic device 300i from the bicycle 120i, which may assist in rendering the theft prevention and tracking solution more effective.
The electronic device 300i may be compartmentalized within the bicycle 102i at the time of manufacturing of the bicycle 102i or may be compartmentalized within an existing bicycle not equipped with an electronic device. Preferable, the electronic device 300i within the bicycle 102i is embedded in a portion of the bicycle that cannot be easily tampered with, without dismantling parts of bicycle 102i. For example, but without being limited to, compartmentalizing the electronic device 300i within the handle bars 202 of the bicycle 102i. In other embodiments, the electronic device 300i may be compartmentalizing within the down-tube, steer-tube, gear hub, rear dropout, or any other suitable location of the frame of the bicycle 102i. It is appreciated that ease and reliability may be among the factors considered for determining the location to compartmentalize the electronic device 300i within the bicycle frame. For example, compartmentalizing the electronic device 300i within the down-tube may be less convenient than other possible locations, but may be more tamper-proof; the steer tube may be a suitable location to compartmentalize the electronic device 300i, as it is typically convenient to compartmentalize the electronic device 300i within the steer tube and may be relatively tamper-proof; the gear hub and rear dropout, may be relatively convenient locations within which to compartmentalize the electronic device 300i, but may possibly be more easily tampered with.
In some cases, the location of the electronic device 300i may be within the bicycle 102i or within a part of the bicycle 102i that can be replaced, such as for example, but without being limited to, the handle bars 202 and/or or the seat. It is appreciated that by compartmentalization of the electronic device 300i in a part of the bicycle 120i that can be replaced may allow for that part of the bicycle 120i to be replaced if the electronic device 300i breaks down, if that part of the bicycle 120i is stolen, or if the cyclist wishes to upgrade the electronic device 300i to a newer make or model.
As it will likely become more readily apparent later on, such a configuration of the electronic device 300i compartmentalized within the bicycle 102i may allow for the electronic device 300i to communicate, directly or indirectly, with the server 108 via one of the wireless network access points 104 and/or other electronic devices 300 of other bicycles 102 without the use of an external communication device.
In other embodiments, the electronic device 300i may not be compartmentalized or embedded within the bicycle 102i but rather may be embodiment as part of a device external to the bicycle and which can be fastened to the bicycle 102i using suitable fastening components. For example, the external device may be fastened to the bicycle 102i by a plastic and/or metal mounting mechanism which may be clipped or screwed onto a component of the frame or other part of the bicycle 102i. Many suitable types of mounting mechanisms for fastening devices to bicycles have be made and many are commercially available mounts, for example, by RAM MOUNTS™ (National Products, Inc) and other manufacturers/vendors. It is to be appreciated the type of mounting mechanism used is not critical to the functionality contemplated in the present description is thus will not be described in further detail here.
In yet other embodiments, the electronic device 300i may not be compartmentalized or embedded within the bicycle 102i but rather may be embodiment as part of a device external to the bicycle and which can be carried by the cyclist (e.g., in a pocket or in a bag that the cyclist is carrying).
The processor 302 may be implemented using any suitable hardware component for implementing a central processing unit (CPU) including a microcontroller, field-programmable gate array (FPGA), application-specific integrated circuit (ASIC), digital signal processor (DSP), an integrated circuit (IC) or any other suitable device. The processor 302 is in communication with the computer readable memory 304, such that the processor 302 is configured to read data obtain from the computer readable member 304 and execute instructions stored in the computer readable memory 304 and to control the various components of electronic device 300i. In some implementations, the processor 302 executes instructions stored in the computer readable memory 304 to derive information useful to the user of the bicycle 102i based at least in part on at the metrics obtained by the sensors 308, such as for example information regarding speed, inclination, distance, location, duration or any other suitable information that may be of interest to the user.
The computer readable memory 304 may be any type of non-volatile memory (e.g., flash memory, read-only memory (ROM), magnetic computer storage devices or any other suitable type of memory) or semi-permanent memory (e.g., random access memory (RAM) or any other suitable type of memory). Although only a single computer memory 304 is illustrated, the electronic device 300i may have more than one computer readable memory module. The computer readable memory 304 may store program code and/or instructions which may be executed by the processor 302. The computer readable memory 304 may also include one or more databases for the storage of data.
The communication module 306 includes an antenna suitable for transmitting data from the electronic device 300i and/or receiving data intended for the electronic device 300i. The communication module 306 may be operationally connected to the processor 302 for instructing it as to which data is to be transmitted and/or for forwarding to it received data for processing. The communication module 306 may include one or more modules for communicating with third party device using a Wi-Fi protocol (e.g., IEEE 802.11 protocol), Bluetooth protocol, cellular network protocol(s) (e.g., GSM, AMPS, GPRS, CDMA, EV-DO, EDGE 3GSM, DECT, IS-136/TDMA, iDen, LTE or any other suitable cellular protocol), ZigBee protocol (e.g., IEEE 802.15 protocol), protocols operating in the 900 MHz, 2.4 GHz, 5.6 GHz ranges, or any other suitable protocol or any combination thereof. Although only a single communication module 306 is illustrated in the electronic device 300, different communication modules may be used to implement different communication protocols. The communication module 306 may be used to communicate, directly or indirectly, with communication modules present in other bicycles, to communicate with Wi-Fi hotspot access points, to communicate with a cellular network, to communicate with a mobile device (e.g., cellular phone, tablet or any other suitable device) or to communicate with any other suitable third party device.
The electronic device 300i has an identifier for uniquely identifying the electronic devices 300i to the network 100. The identifier may be a media access control (MAC) address, IP address (e.g., IPv4 or IPv6 address) or any other suitable identifier allowing to uniquely identify the electronic device 300i. In some cases, the identifier is a network address assigned to the electronic device 300i. The assigned network address may be a static network address. This static network address may be assigned to the electronic devices 300i before the bicycle 102i is shipped and sold to the cyclist or distributor, during an initial registration process or at another suitable time. In another non-limiting embodiment, the electronic devices 300i may be assigned a dynamic network address. For example, in a non-limiting scenario, a Dynamic Host Configuration Protocol (DHCP) server (not depicted) may be used to assign the dynamic network address (such as, for example, a dynamic IP address) to the electronic devices 300i.
It is appreciated that the identifiers of the electronic devices 300 may be network addresses that may be used to specifically identify each of electronic devices 300 (e.g., nodes) in the network 100. By being able to specifically identify each of electronic devices 300 (e.g., nodes), it may be possible to route communications to specific electronic devices 300 (e.g., nodes) in the network. As the use of network addresses for routing communication between different nodes in a network is within the knowledge of the person of skill in the art, it will not be described in further detail here.
The sensors 308 may include one or more sensors for detecting any suitable metric related to the use of bicycle 102i, including for example speed, pace, acceleration, distance, time, incline, decline, altitude, torque, power generated, cadence, orientation, gear, location, latitude, longitude, elevation, yaw-pitch roll, angular velocity (in three dimensions), linear acceleration (in three dimensions), or any other suitable metric.
It is appreciated that the relative orientation of the cyclist relative to the ground they are riding on may be useful for applications concerned with pot-hole detection, crash detection and the like. In addition to event detection, such as pot-hole detection and crash detection, the orientation of the cyclist may be used in calculating the number of calories burned by the cyclist. It is also appreciated that torque may be usefully for calculating how much energy the cyclist is exerting. It is also appreciated that cadence may be useful for determining how frequently the cyclist is shifting gears.
Although the sensors 308 are illustrated as internal to the electronic device 300i, in other cases some of the one or more sensors 308 may be external to the electronic device 300i and may be connected to different parts of the bicycle 102i in order to collect various suitable measurements of the type mentioned above. In the cases where some of the one or more of the sensors 308 are external to the electronic device 300i, the sensors 308 may be connected to the electronic device 300i via the input/output circuitry 310. Any suitable type of sensors 308 can be used to determine one or more of these aforementioned metrics, including for example a 9-axis inertial monitoring unit, Hall effect sensor, a magnetic sensor, a strain gauge, a photo-electric sensor, an accelerometer, positioning circuitry (e.g., Global Positioning System (GPS) circuitry), a Barometer, a real-time clock (RTC), a motion sensor, a ultra-sonic detector, a gyroscope, a magnetometer, a speedometer, a temperature sensor, torque sensor, cog counter or any other suitable sensor. The sensors 308 provide suitable metrics related to the use of bicycle 102i depending on the sensors functionality and the suitable metrics related to the use of bicycle 102i may be provided in the form of data which can be stored in the computer readable memory 304 and/or processed by the processor 302. Suitable sensors for collecting metrics related to use of a bicycle or other vehicles have been used in the past and the specific manner in which such sensor collect metrics is not critical and goes beyond the scope of the present document and thus will not be described in further detail here.
The input/output circuitry 310 may be used to connect to one or more external sensors and may be used for receiving information conveying various metrics related to the use of bicycle 102i. The input/output circuitry 310 may also be used to release information to the user of the bicycle 102i to convey to the user information derived by the processor 302 based at least in part on the metrics obtained by the sensors 308 or other relevant data or information. In a non-limiting example, the input/output circuitry 310 may be connected to a plurality of display element, such a display screen, light element (LEDs for example) or other visual elements for conveying information to a user of the bicycle 102i. For example, as illustrated in
The electronic device 300i also includes a power source 312, which may be embodied as a battery (e.g., lithium battery, alkaline battery, metal hydride battery, nickel metal hydride battery or any other suitable battery), a power generator connected to a wheel or other part of the bicycle 102 that is able to provide power when the bicycle is in movement (e.g., a dynamo) or any other suitable power source. Batteries and bicycle dynamo generators are commercially available and are commonly known to the person skilled in the art and, as such, are not discussed in detail in this document. The electronic device 300i may have an outlet for recharging the power source 312 by connecting the outlet to an AC or DC power source (e.g., a 120 volt AC outlet or any other suitable outlet).
As shown in
The computer readable memory 404 may also stored a set of executable instructions in the form of application software implementing various functionality/applications and which are executable by the processor 402. The application software may include an application that allows a user to create an account, allows the user to associate that account with one or more bicycles, allows a user to login to the account to view information, allows for the server to obtain and store information related to the use of bicycles, allows a user to view current and previous locations of the one or more bicycles associated with his/her account, allows a user to report a bicycle stolen, allows for the server to notify the user of a location of a stolen bicycle, and other operations a few of which will be discussed throughout this document.
The communication module 406 may be any suitable module for communicating with the data network 106 (e.g., Ethernet module, Wi-Fi module, optical communication module, or any other suitable device). Although not illustrated the connection of the communication module 406 to the data network 106 may include the use of an access device (e.g., a modem, such as cable modem, an xDSL modem, an Optical Network Terminal (ONT) or any other suitable device).
Referring back to
In a non-limiting embodiment of the present invention, the access connection 111 between the server 108 and the data network 106 and the access connections 1141 1142 between the data network 106 and the wireless network access points 1041 1042 may be a copper twisted pair over which higher-layer protocols allow for the exchange of packets (e.g., an xDSL-based access link), an Ethernet link, a fiber optic link (e.g., Fiber-to-the-Premise, Fiber-to-the-Curb, etc.), a wireless link (e.g., EV-DO, WiMax, Wi-Fi, CDMA, TDMA, GSM, UMTS, and the like), coaxial cable link, or any other suitable link, or a combination thereof. Generally speaking, the access connections 1111141 1142 may comprise any type of wireless, wired or optical connection that allows exchange of data between the server 108, the data network 106 and the wireless network access points 1041 1042.
As shown in
The network access device 520 may comprise a modem that is connected to a link (e.g., the link 1141 or 1142) to an Internet service provider. Examples of modems that can be used include, but are not limited to, a cable modem, an xDSL modem and the like. In alternative embodiments of the present invention, which are particularly applicable where the access connections (e.g., the links 1141 or 1142) comprise Fiber-to-the-premise, the network access device 520 may comprise an Optical Network Terminal (ONT). Naturally, the type of the network access device 520 depends on the type of the access connections (e.g., the links 1141 or 1142) employed.
In a specific embodiment, the Wi-Fi access device 510 includes a wireless router. Examples of wireless routers that can be used include, but are not limited to, routers that implement Wi-Fi/IEEE 802.11 protocol (e.g., 802.11a, 802.11g, 802.11n, 802.11ac or any other suitable protocol). Wireless routers of this type are commercially available and are within the knowledge of the person of skill in the art and, as such, are not discussed in detail in this document. The connection of the Wi-Fi access device 510 to the network access device 520 allows for access to the data network 106 (e.g., Internet access) to be provided to devices, such as but not limited to the electronic device 300i, that may connect to the Wi-Fi access device 510.
In some embodiments of the invention one or more of the wireless network access points 104 are open Wi-Fi access points or open Wi-Fi hotspots. Wi-Fi hotspots are often found at airports, bookstores, coffee shops, department stores, fuel stations, hotels, hospitals, libraries, public pay phones, restaurants, RV parks and campgrounds, supermarkets, train stations, schools, universities and other public places. In general, a Wi-Fi hotspot is “open” or “free” if the Wi-Fi access device 510 (e.g., the Wi-Fi router) provides an open public network in which device employing an accepted Wi-Fi standard is in range of the Wi-Fi access device 510 can connect to. The Wi-Fi access device 510 is configured for accepted connections requests made by any device with little, if any, restriction on the Wi-Fi enabled devices that may connect to it. For instance, in the case of the electronic device 300i connecting via the communication module 306 to the open Wi-FI access device 510, the electronic device 300i may gain access to the data network 106, without having to providing authentication or access information (e.g., a username and/or password) or undergo an analogous access control process.
In other cases the Wi-Fi hotspot is “open” or “free” but employs a closed public network and may use a hotspot management system to limit access to its network. In such cases, software may run on the Wi-Fi access device 510, or on an external computer, allowing operators of the wireless network access point 104i to authorize only specific users to access the data network 106. In other words, a restriction is placed on the Wi-Fi enabled devices that may connect and gain access to the public network.
By way of example, when the bicycle 102i of the set of bicycles 102 passes within range of the wireless network access point 104i (e.g., a Wi-Fi hotspot) it may detect and connect to the wireless network access point 104i to gain access to the server 108 and then the server 108 and the bicycle 102i may communicate with each other. When the open Wi-Fi hotspot provides an open public network, the bicycle 102i may gain access to the server 108 by physically entering the range of the Wi-Fi hotspot and then connecting to the Wi-Fi hotspot to then gain access to the public network using known methods. In such a case, the bicycle 102i may then upload to the server 108 bicycle use information of one or more of the bicycles 102 or any other suitable information. In other cases, where the open Wi-Fi hotspot provides a closed public network, additional steps may be required to be taken for the bicycle 102i to gain access to the public network 106 and hence to the server 108. In order to gain access to Wi-Fi hotspot that provide closes public networks, access information may be stored in the computer readable memory 304 of the electronic device 300i of the bicycle 102i. When such a Wi-Fi hotspot is detected, in order to gain access to the network 106, the bicycle 102i can provide the access information to the open Wi-Fi hotspot that provides a closed public network to gain access to the public network and then to the server 108.
More specifically, the additional steps that may be required by the bicycle 102i to gain access to Wi-Fi hotspots that provide a closed public network and/or use a hotspot management system to control access, may include the communication module 306 of the electronic device 300i first connecting to the Wi-Fi hotspot (e.g., Wi-Fi access device 510) and then secondly providing access information, such as, a user name and/or a password, passcodes, or providing some other indicator to indicate to the wireless network access point 104 that the electronic device 300i is authorized to gain access. Once the electronic device 300i gains access to closed public network, the electronic device 300i may then communicate to the server 108 via the data network 106.
It is appreciated that, in some cases, an agreement may be made with the manufacturer, distributors or users of the bicycles 102 to gain access to Wi-Fi hotspots that provide a closed public network and/or use a hotspot management system to control access to the hotspot. When such agreements are made the access information (such as passcodes) may be stored in the computer readable memory 304 of the electronic device 300i of the bicycle 102i prior to the bicycle 102i entering in the range of the Wi-Fi hotspots that provide a closed public network. This access information may be programmed into the computer readable memory 304 of the electronic device 300i by the server 108 or may be programmed into the computer readable memory 304 of the electronic device 300i prior to the cyclist purchasing the bicycle 102i. In other words, the computer readable memory 304 of the electronic device may include a record of available Wi-Fi hotspots that require authentication with a hotspot management system and the relevant access information (e.g., password, username, or other suitable indicators) to gain access. Alternatively, such information may be programmed using any other suitable mechanism including but not limited to any suitable mechanisms for updating and upgrading firmware in electronic devices.

Registration of Bicycles with a Server 108
After the purchase of the bicycle 102i and/or the electronic device 300i, the bicycle 102i and/or the electronic device 300i may have to be registered with the server 108 in order for the electronic device 300i to function within the network 100 and provide its user with network enhanced functionality. For example, the registration of the bicycle 102i and/or the electronic device 300i with the server 108 may take place as discussed below.
A user (for example, the owner of the bicycle 102i) may connect with a computing device (e.g., cell phone, tablet, computer, and the like) to the server 108 over the data network 106 (e.g., the Internet) via a web browser or any other suitable application (e.g., mobile phone application). The user may be prompted to create a new account, if the user does not have an existing account with the server 108. This account creation may include entering in a name, username, password, email address, contact information and/or any other suitable information.
Once the account associated with the user is created or during the account creation process, the server 108 may request from the user that the user provide an identifier associated with the bicycle 102i and/or the electronic device 300i, so that the server 108 can associate the bicycle 102i and/or the electronic device 300i with the user's account.
In some cases, the unique identifier of the electronic device 300i is associated with a unique user in the server 108. For example, when the bicycle 102i is purchased the unique identifier may be stored in the database 408 of the computer readable memory 404 of the server 108 in association with the purchaser's user information, such as, name, email, and any other suitable information. For instance, when the bicycle 102i is ordered online the user information of the user (e.g., the purchaser) may be obtained and prior to the bicycle being shipped to the user, the unique identifier of the electronic device 300i may be recorded in the database 408 is association with user information. In other words, when the user orders the bike the user may create an account with the server 108 and the server 108 may then be able to store the unique identifier of the electronic device 300i in association with the user.
By way of another example, after the user receives the bicycle 102i, the user may register with the server 108, for example by connecting to the server with a computing device (e.g., computer, cell phone, tablet or any other suitable device) and entering in the serial number provided with the bicycle 102i/electronic device 300i.
Yet in other cases, after the user receives the bicycle 102i the user may be required to connect the electronic device 300i to a portable computing device (e.g., computer, cell-phone, tablet or any other suitable device) which may take place over a Bluetooth connection or near-field communication (NFC) connection and an application running on the portable computing device may obtain the unique identifier of the electronic device 300i from the electronic device 300i. This application running on the portable computing device may then communicate with the server 108, such that the portable computing device provides the server 108 with the unique identifier of the electronic device 300i and the user information of the user. It is appreciated that in this case, that the user may not have to manually entering the unique identifier. Then the server 108 may record the unique identifier in association with the user's account.
It is also appreciated that, in these examples, the unique identifier may be the MAC address of the communication module 306. For example, the unique identifier may be the MAC of a Wi-Fi module or the MAC address of a Bluetooth module. In some cases, the unique identifier may be more than one unique identifier; for example, the MAC of a Wi-Fi module and the MAC address of a Bluetooth module.
Yet, in other cases, the provided identifier (e.g., the serial number) is only identifier stored in association with the bicycle 102i and/or the electronic device 300i in the user's account.
Regardless of the type of identifier used, it is appreciated that in these examples that each of the electronic devices 3001 3002 3003 3004 of the respective bicycles 1021 1022 1023 1024 has a unique identifier. The identifiers of the electronic devices 3001 3002 3003 3004 may be factory set identifiers or may be identifiers that are received at the electronic devices 3001 3002 3003 3004 when the electronic devices 3001 3002 3003 3004 are registered with the server 108.
At the registration stage, the user/owner of the bicycle 102i may be required to connect the electronic device 300i to the server 108 via the communication module 306 of the electronic device 300i. This may include connecting the electronic device 300i to a wireless network access point 104i or to a portable computing device (e.g., a cellular phone over Bluetooth) which is connect to a cellular network. At this registration stage, the electronic device 300i may be provided with the unique identifier and/or may be updated with relevant information. For example, the electronic device 300i may be updated with a list of other the electronic devices 300 that it may communicate with. For example, the list of other electronic devices 300 that it may communicate with may be a list of identifiers of the other electronic devices 300 (e.g., list of MAC addresses, list of IP addresses, or list of other suitable identifiers). At this stage, the electronic device 300i may be updated with a list of records of available Wi-Fi hotspots that require authentication with a hotspot management system and the relevant data (e.g., password, username, or other suitable indicators) to gain access.
For illustration purposes, in these specific and non-limiting examples, the electronic devices 3001 has the identifier “00001”, the electronic devices 3002 has the identifier “00002”, the electronic devices 3003 has the identifier “00003”, and the electronic devices 3004 has the identifier “00004”. In other words, each bicycles 1021 1022 1023 1024 has an identifier associated with it, where each identifier can be used to uniquely identify a respective bicycle 1021 1022 1023 1024. It is appreciated that the length of the identifier may be any suitable length alpha and/or numeric number, binary number, hexadecimal number and the like. It is appreciated that in the specific and non-limiting examples presented in this document, the identifiers “00001”, “00002”, “00003” and “00004” are used for illustrative purposes only and the identifiers may be in some implementations serial numbers, MAC addresses, IP addresses, any other suitable network addresses, or any other suitable identifiers.
Referring back to
As previously discussed, the electronic device 300i has one or more sensors 308. In this example the sensors 308 include a GPS and Barometer for detecting latitude, longitude and elevation as function of time. Although this example is limited to GPS and Barometer for detecting latitude, longitude and elevation as function of time, it is appreciated that this example could equally apply to other types of sensors 308 (such as those listed elsewhere in this document) for collecting other suitable metrics related to the use of bicycle 102i (such as those listed elsewhere in this document). In this example, when position information (e.g., latitude, longitude and elevation data) is recorded the date and time of obtaining this position information is also record. The date and time date may be obtained by the GPS, from a real-time clock (RTC) or any other suitable device. In this example the sensors 308 also includes a motion sensor for detecting when the bicycle 102i is in motion.
It is appreciated that this example is a simplified example of information that may be determined by the electronic device 300i In other cases, the electronic device 300i may be configured such that the GPS and Barometer determine latitude, longitude and elevation as function of time and the electronic device 300i is also configured such that orientation, speed, weather data and/or linear acceleration is also determined. It is appreciated that in some cases, the latitude, longitude, elevation and time may be obtained from the GPS. In other cases, elevation may be obtained from an accelerometer, gyroscope, barometer and/or magnetometer. Orientation in space may be obtained from a gyroscope, accelerometer and/or magnetometer. Speed may be obtained from a speedometer, which may monitor the frequency of an alternator. It is appreciated that relative position may be obtained from the gyroscope, accelerometer, magnetometer and/or speedometer. Weather data may also be obtained via the GPS or a Wi-Fi connection, which originate from public servers (e.g., The Weather Network). In some cases, the barometer data may be cross-referenced with the weather data to get local data which is possibly more specific. Linear acceleration may be obtained by the accelerometer and altitude from the barometer. In some cases an ultra-sonic detector may be used for blind-spot monitoring. For example, one or more rear-facing range sensors, such as ultrasonic sensors, can be mounted to the frame of the bicycle. Processor 302 can be configured to receive and process data from such sensors to determine whether an object—such as a vehicle—is present within the range (e.g. within about three meters) of the sensors. When the determination is affirmative, processor 302 can control an output device, such as motors 291, visual indicators 210, or both, to generate a warning to the operator of bicycle 102.
When the bicycle 1021 is in motion, the motion sensor in the electronic device 3001 detects that bicycle 1021 is in motion and that position information (e.g., latitude, longitude and elevation data) may be measured and recorded. The position information can be obtained from the sensors 308 of the electronic device 3001 and then stored in a database in the computer readable memory 304 of the electronic device 3001.
In this example, the position information is recorded every one second; however, it is appreciated that the position information may be recorded at any other suitable interval (e.g., every millisecond, every microsecond, every couple of seconds, every minute, every couple of minutes, every hour, and the like). Furthermore, in this example only three data points at three different times are illustrated; however, it is appreciated that the position information recorded in the computer readable memory 304 of the electronic device 3001 would typically contain more than three different data points and would contain data points at intervals over a period of time corresponding to the time the bicycle 1021 is moving.
Similarly,
As in the example above, it is appreciated that in this example the position information is not limited to the time interval and number of data points illustrated.
Similarly,
As in the example above, it is appreciated that in this example the position information is not limited to the time interval and number of data points illustrated.
Similarly,
It is appreciated that such a configuration of the electronic device 300i of the bicycle 102i allows for the collecting of data relating to suitable metrics to the use of bicycles 102i when the bicycle 102i is in motion. Such data may then be transmitted, directly or indirectly, to other electronic devices 300 associated with other bicycles 102 or to a server 108 for storage. In addition, the data may also be accessed by a user using the bicycle 102i in real-time via a portable electronic device (e.g., cell phone, tablet, and the like) connected to the electronic device 300i or by the user at a later time by accessing the electronic device 300i or the server 108.
It is also appreciated that the computer readable memory 304 of the electronic device 300i may have a limited capacity and may only keep track of position information for a limited amount of time. For example, the electronic device 300i may only keep track of the last 4 hours of bicycle use data. While in other cases, the electronic device 300i may only keep track of more or less than the last 4 hours of bicycle use data. Yet in other cases, the electronic device 300i keeps track of bicycle use data until the electronic device 300i is able to directly or indirectly connect with the server 108 and if the computer readable memory 304 is full prior to connecting with the server 108, deleting part of the oldest bicycle use data to make room for new bicycle use data.
Referring back to
In this specific example, it is assumed that the electronic device 3001 of the bicycle 1021 is not connected to the wireless network access point 1041 over the wireless link 1151, that at a first point of time (t=1) the electronic device 3001 of the bicycle 1021 connects to the electronic device 3002 of the bicycle 1022, and that at a second point of time (t=2) the electronic device 3001 of the bicycle 1021 connects to the electronic device 3003 of the bicycle 1023.
At a first point of time (t=1) when the two bicycles 1021 1022 are in a wireless connectivity range of each other, the two bicycles 1021 1022 may connect to each other according to the steps of the flowchart 800. At step 802, the electronic device 3001 of the bicycle 1021 connects to the electronic device 3002 of the bicycle 1022 over the wireless link 1161. This step may include an authentication protocol to facilitate the connection. At step 804 the electronic devices 3001 transmits its identifier and some or all of the data stored relating to the metrics related to the use of bicycles 102 or any other suitable data stored in the computer readable memory 304 of electronic devices 3001 to the electronic devices 3002. At step 805 the electronic devices 3001 obtains from the electronic devices 3002 the identifier of the electronic devices 3002 and some or all of the data stored relating to the metrics related to the use of bicycles 102 or any other suitable data stored in the computer readable memory 304 of electronic devices 3002. This exchange of identifiers and data may take place in a half-duplex communication, in which the electronic device 3001 first communicates its identifier and data to the electronic device 3002 and then the electronic device 3002 later communicates its identifier and data to the electronic device 3001. Then at step 806 the received data and identifier can then be stored in the computer readable memory 304 of each respective electronic device 3001 3002.
At a second point of time (t=2) when the two bicycles 1021 1023 are in a wireless connectivity range of each other, the two bicycles 1021 1023 may connect to each other according to the steps of the flowchart 800. Similar to the steps in the example above, the electronic devices 3001 3003 of the two bicycles 1021 1023 would establish a connection over the wireless link 1162, exchange identifiers and data, and store the data in association with respective identifiers.
Although in the example above the communication modules 306 of the electronic devices 3001 3002 3003 use Wi-Fi protocol, any other suitable communication protocol could be used (as discussed elsewhere in this document).
In other cases, instead of exchanging data relating to historic metrics of use of the bicycles, each of the electronic devices 3001 3002 3003 may record the current position information (e.g., latitude, longitude and elevation data) of each other's bicycles when in range of each other. For example, when the electronic device 3001 is in range of the electronic device 3002, the electronic devices 3001 could record the identifier “00002” of the electronic device 3002, and the current position information (e.g., latitude, longitude and elevation data) of the bicycle 1022 associated with the identifier “00002” of the electronic device 3002, along with the date and time of this interaction. Similarly, in this example, the electronic devices 3002 could also record the identifier “00001” of the electronic device 3001, and the current position information (e.g., latitude, longitude and elevation data) of the bicycle 1021 associated with the identifier “00001” of the electronic device 3001, along with the date and time of this interaction.
As discussed in the example above, the first electronic devices 3001 may exchange its identifier and possibly some or all of the data stored relating to the metrics related to the use of bicycles 102 or any other suitable data stored in the computer readable memory 304 of the first electronic devices 3001 to the second electronic devices 3002. However, in other cases, only the identifier of the electronic devices 300 may be exchanged. Yet in other cases, when certain conditions are met, in addition to the identifier of the electronic devices 300 being exchanged, other information relating to use of the bicycles 102 may be exchanged.
Referring back to
In this example, at step 902 the bicycle 1021 connects to the wireless network access point 1041 over a wireless link 1151 between the communication module 306 of the electronic device 3001 and the Wi-Fi access device 510 of the wireless network access point 1041. This step may include an authentication protocol to facilitate the connection. Then as step 904 the electronic device 3001 transmits the data it has stored relating to the use of the various bicycles 1021 10221023 to the wireless network access point 1041. Then the wireless network access point 1041 transmits the received information to the server 108 via the data network 106. The server 108 can then store the received information in the database 408 of the computer readable memory 404.
It is appreciated that such a configuration may allow for various data relating to the use of the various bicycles 1021 1022 1023 to be shared among the bicycles 1021 1022 1023 when none of the bicycles 1021 1022 1023 are in range of the wireless network access points 104 such that when one of the bicycles 1021 1022 1023 does enter range of one of the wireless network access points 104 that the various data relating to the use of the various bicycles 1021 1022 1023 is transmitted to the server 108.
Furthermore, in this example, the process 900 can be repeated for the bicycle 1024. At step 902 the bicycle 1024 connects to the wireless network access point 1042 over a wireless link 1152 between the communication module 306 of the electronic device 3004 and the Wi-Fi access device 510 of the wireless network access point 1042. Then at step 904 the electronic device 3004 transmits the data it has stored relating to the use of bicycle 1024 to the wireless network access point 1042. Then the wireless network access point 1042 transmits the received information to the server 108 via the data network 106. The server 108 can then store the received information in the database 408 of the computer readable memory 404.
It is appreciated that such a configuration may allow for the server 108 to record data relating to various bicycles 1021 1022 1023 1024 when only select bicycles (in this example above bicycles 1021 1024) come into range of a Wi-Fi hotspot. In other words, in this example, the server 108 obtained data relating to the use of the bicycles 1021 and 1024 directly from the bicycles 1021 and 1024 and obtained data relating to the use of the bicycles 1022 and 1023 indirectly via bicycle 1021.
It is also appreciated that such a configuration may allow for the electronic devices 3001 3002 3003 3004 to communicate amongst each other without the use of an external communication device (such as a mobile or cellular telephone). It is also appreciated that such a configuration may allow for one or more of the electronic devices 3001 3002 3003 3004 when in range of one of the wireless network access points 1041 1042 to communicate with the server 108 via one of the wireless network access points 1041 1042 and the data network 106 without the use of an external communication device (such as a mobile or cellular telephone).
In the examples above, it is assumed that the electronic device 3001 of the bicycle 1021 is not connected to the wireless network access point 1041 over the wireless link 1151 when the electronic device 3001 of the bicycle 1021 connects to the electronic devices 3002 3003 of the respective bicycle 1022 1023 via respective wireless links 1161 1162 and vice versa. However, in other embodiments, the electronic device 3001 of the bicycle 1021 connects to both the electronic devices 3002 3003 of the respective bicycle 1022 1023 while being connected to the wireless network access point 1041. In these embodiments, where the electronic device 3001 of the bicycle 1021 is connected to the wireless network access point 1041 over the wireless link 1151, is also connected to the electronic device 3002 3003 over the respective wireless links 1161 1162, wireless bridges are formed between the electronic devices 3001 3002 3003 which may allow for data to be transmitted from either of the electronic devices 3002 3003 not directly connect to the wireless network access point 1041 via the electronic devices 3001 which is connect to the wireless network access point 1041. Then the data at the wireless network access point 1041 can be transmitted to the server 108 via the data network 106.
It is appreciated that such a wireless bridge configuration of the mesh network may allow for bicycles 1022 1023 out of range of the wireless network access points 1041 1042 to connect to the server 108 via the bicycle 1021 that is in range of the wireless network access points 1041. In other words, the communication modules 306 of the electronic devices 3001 3002 3003 function as Wi-Fi routers which wireless bridges with each other, to possibly extent the range of the network 100.
It is also appreciated that such a configuration may allow the bicycle 1024 which is out of range of a wirelessly connected group of bicycles 1021 1022 1023 to connect to the wirelessly connected group of bicycles 1021 1022 1023, as the range of the network 100 may extend across all wireless network access points 1041 1042 and all groups of connected bicycles (e.g., the first group of wirelessly connected bicycles 1021 1022 1023 and the second group of wirelessly connect bicycles 1024) connect to the wireless network access points 1041 1042.
In these examples, the wireless network access points 104 which are implemented as Wi-Fi hotspots may be open public network hotspots or closes public network hotspots which may use a hotspot management system to control access (as discussed elsewhere in this document). By way of example, if the wireless network access point 1041 is an open public network Wi-Fi hotspot the electronic device 3001 would be able to connect to the wireless network access point 1041 to gain access to the data network 106 and to the server 108 without having to provide any authentication, other than connecting using Wi-Fi protocol to the wireless network access point 1041. By way of another example, if the wireless network access point 1042 is a closed public network Wi-Fi hotspot employing a hotspot management system, the electronic device 3004 would typically be able to connect to the wireless network access point 1042 using Wi-Fi protocol but would typically have to provide additional information to the hotspot management system in order to gain access to the close public network of the wireless network access point 1042 and then connect to the server 108 via the data network 106. In this example, the additional information may be a username and/or password, or any other suitable indicator which may be stored in the computer readable memory 304 of the electronic device 3004.
It is also appreciated that in the examples above when the data is transmitted to the server 108, that the server 108 may require a form of authentication (e.g., username and/or password, or any other suitable indicator) to authenticate the user and/or electronic device 300 that the data is being transmitted from.
In these examples, once an electronic device 300i associate with the bicycle 102i is connected to the server via a wireless network access point 104i, the electronic device 300i periodically may update the server 108 with the bicycle use data relating to the bicycle 102i and any other bicycle use data that the bicycle 102i obtains from the electronic devices 300 associate with other bicycles 102.
The network 100′ shown in
This example is a continuation, at least in part, of the previous examples regarding the bicycles 1021 1022 1023 1024 collecting data and the bicycles 1021 obtaining data from the bicycles 1022 1023. Turning now to
In this example, at step 1102 the communication module 306 of the electronic device 3001 connects to the external communication device 1521 which may take place over Bluetooth protocol (or any other suitable protocol, as discussed elsewhere in this document). As the external communication device 1521 is connected via a cellular network protocol to the wireless network access point 104′1, then at step 1104 the communication module 306 of the electronic device 3001 can communicate to the external communication device 1521 which can then transmit the data to the wireless network access point 104′1. At this step the data transmitted may include the data stored relating to the use of the various bicycles 1021 1022 1023 to the wireless network access point 1041, similar to the data transmitted in step 904 of the example above. Then the wireless network access point 104′1 transmits the received information to the server 108 via the data network 106. The server 108 can then store the received information in the database 408 of the computer readable memory 404. Then as step 1106 the server 108 may send any relevant data or commands to the electronic device 3001 via the wireless network access point 104′1 and the external communication device 1511.
Similarly, the electronic device 3004 of the bicycle 1024 may connect to the wireless network access point 104′2 via the external communication device 1522 and then transmit and receive data from the server 108.
It is appreciated that in some embodiments of the invention that some of the wireless network access points 104 may be implemented as Wi-Fi hotspots and some of the wireless network access points 104′ may be implemented as cellular network access points. Such a configuration may allow a set of users of the bicycles 102 that wish to use their cellular phones or other mobile communication devices to be able to communicate with the server 108 via their cellular phones or other mobile communication devices, while allowing another set of users of the bicycle 102s that are not making use of cellular phones or other mobile communication devices to connect via Wi-Fi hotspots. Such a configuration may allow a set of the communication devices 300 of the bicycles 102 to communicate with each other over Wi-Fi regardless of which set of the communication devices 300 are connected to one of the wireless network access points 104104′ or the type of wireless network access point (e.g., Wi-Fi or cellular).
The owner of the bicycle 102i may connect with a computing device (e.g., cell phone, tablet, computer, and the like) to the server 108 over the data network 106 (e.g., the Internet) via a web browser or any other suitable application (e.g., mobile phone application). The owner may be prompted to provide credential information to login to the server 108 to view information associated with the user's account. Once the user has authenticated himself/herself to the server 108, the user can then request to view position information associated with one of the bicycles 102 associated with the user's account.
It is appreciated that such a configuration may allow for a user to view in real-time the position information of a bicycle 102i as the server 108 can continue to obtain position information from the bicycle 102i as long as the bicycle 102i is connected directly or indirectly to the server 108.
Referring back to
Turning now to
At step 1204, the server 108 continues to receive data from the bicycles 102 in the fashion similar to the examples discussed elsewhere in this document where the one or more of the bicycles 102 connects to wireless network access points 104 (or 104′).
In this example, once the bicycle 1023 starts to move (e.g., based on output from a motion sensor), the electronic device 3003 starts to record position information (e.g., longitude, latitude, and elevation data) along with the date/time.
In the case where electronic device 3003 is unable to connect to the server 108 directly or indirectly via one of the wireless network access points 104 or through one of the other electronic devices 3001 3002 3004, the electronic device 3003 continues to record position information.
Now in this example, the electronic device 3001 of the bicycle 1011 comes into wireless connectivity range of the electronic device 3003 of the bicycle 1023 and the bicycle 1011 can obtain the position information of bicycle 1023 including the date/time of the position information and the identifier “0003” of the bicycle 1023 associated with the position information.
Then when the bicycle 1011 comes into wireless connectivity range of the wireless network access point 1041, the electronic device 3001 of the bicycle 1011 transmits the position information and the server 108 receives the data corresponding to the position information of bicycle 1023 (step 1204). This position information can then be added to table 1001″ stored in the database 408 of the computer readable memory 404 of the server 108, where table 1001″ is an updated version of table 1001′ to include the latest obtained position information.
Although in this example, the position information is received at the server 108 via the wireless network access point 1041 which may be implemented as a Wi-Fi hotspot. In other examples, the position information could be received at the server 108 via the wireless network access point 104′1 which is a cellular network access point via a communication device 1522, such as illustrated in the network 100′ of
In other cases, if the electronic device 3003 enters in range of one of the wireless network access points 104 implemented as Wi-Fi hotspots, the electronic device 3003 may connect to the server 108 via one of the wireless network access points 104 without having to communicate through one of the other electronic devices 3001 3002 3004. Then, the electronic device 3003 would be able to transmit its current position information and historic position information to the server 108, including the date/time of the position information and the corresponding identifier.
Then at step 1206 the server 108 checks the received data by comparing the received identifiers with the identifiers stored in the table 1301, which lists identifiers corresponding to stolen bicycles, to see if a stolen bicycle can be identified. If one of the received identifiers matches with an identifier stored in the table 1301 then the server 108 notifies the owner of the stolen bicycle corresponding to the identified identifier at step 1206. Otherwise, the server continues to monitor the incoming data. The notification to the owner of the stolen bicycle may be, for example, a text message sent to a mobile device associated with the bicycle owner, a visual indicator displayed in a mobile phone application, an email, or any other suitable electronic message to indicate to the owner that information associated with the owner's bicycle has been obtained. In some cases, the notification to the owner may include the position information. In other cases, the owner may have to login to the server 108 with a computing device and can then view the position information. Yet in other cases, the owner may view the position information in a mobile application on a mobile computing device. In these cases, the position information may be displayed on graphical display of the owner's computing device by overlapping the position information on a map along with the date/time of the position information.
In these examples, the server 108 may send a notification back to the electronic device 3003 to indicate to the electronic device 3003 that it is a stolen. In cases where the electronic device 3003 receives a notification that it is stolen, the electronic device 3003 may enter in a mode to function differently, which may include increasing the interval of obtaining position information, not deleting past route information, not obtaining routing information from other bicycle, establishing connections to Wi-Fi hotspots automatically, at the like.
In other examples, the server 108 may transmit the identifiers of stolen bicycles to the electronic devices of the bicycles which are connected to the server 108 and these bicycles may maintain a list of stolen bicycles and actively search for the stolen bicycles, which may then passed to other bicycles that are not connected to the server 108 or do not have the most up-to-date list of stolen bicycles. Then, a bicycle may then maintain the list of stolen bicycles and may then actively search by checking the identifiers of any bicycles that this bicycle makes contact with. Then, in the event that the bicycle has made contact with a stolen bicycle, the bicycle may then send the notification that a stolen bike has been located to the server 108 along with position information of the stolen bicycle. Then the server 108 may then forward this information to the owner of the identified stolen bicycle.
It is appreciated that in the examples when the mesh network 100 comprises wireless network access points 1041 1042 implemented as Wi-Fi hotspots and the electronic device 300 is embedded into the bicycles 102i that the position information of the stolen bicycle may be obtained without the use of any external communication devices.
It is also appreciated that when a stolen bicycle 102i is identifier, the stolen bicycle may be provided (e.g., via the server 108 or another bicycle) with an indication that the bicycle is stolen.
Referring back to
It is appreciated that such a configuration may allow for an automatic alert and notification system allowing an owner of a bicycle to lock his bicycle to a bike rack (or other suitable object) which is in direct or indirect range of a wireless network access point 104 or 104′. After the user locks his bicycle, the user may then send an indication to the bicycle to entering an alert mode to send a notification if the bicycle is attempted to be stolen. This indication may be sent directly to the bicycle (e.g., via Bluetooth or Wi-Fi) or to the server 108 which then sends the indication to the bicycle. Then when the bicycle moves a motion sensor (or other suitable sensor) may detect the movement and sends a notification to the server 108 which may then notify the owner of the bicycle of such movement.
Continuing with the example above, the motion data from the 9-axis inertial sensor (or other suitable sensor) may be used to detect congestion on bicycle paths or routes.
Although in the examples above 9-axis inertial data was used to determine potholes and congestion, in other cases other suitable motion data could be used to make a similar determination in accordance with the invention.
The server 108 may provide the bicycles 102 with route suggestion based of a safety score that is calculated by ranking and analyzing data obtained by the plurality of bicycles 102. For example, congestion, road surface conditions, elevation, inclination, accident frequency, number of left and right turns, speed limit or any other suitable information may be processed by the server 108 to determine route suggestions.
In some cases, server 108 may provide the bicycles 102 with a parking safety score that is calculated by the sever 108 possibly based on reported latitude and longitude coordinates and the time of reported incident of stolen bicycles. This calculated parking safety score may be mapped to provide safety rankings for cyclists desiring to lock their bicycles.
The server 108 may provide a live traffic map that generating a live traffic map of the bicycles 102 from the position information received at the server 108.
In another aspect of this disclosure, the electronic device 300i may be used to automatically control (e.g., shift or change) the gears of a bicycle and/or a continuously variable transmission, without mechanical adjustment of the gears by the cyclist or, alternatively, in complement thereof.
The hub 2302 includes a gear portion 2404. The hub 2302 and gear portion 2404 may be implemented as a Freehub™ including a ratcheting mechanism as part of the hub 2302 and a single sprocket or a cassette containing a set of sprockets (e.g., a cogset or cluster), a freewheel including a ratcheting mechanism separate from the hub 2302 and a single sprocket or a set of sprockets, a track sprocket (e.g., a set of treads on the hub shell 2402 for receiving the sprocket), a flip-flop hub (e.g., both sides of the hub 2302 are threaded, and may be used with a single speed freewheel or a track sprocket, such as a fixed cogs), an internal geared hub, a continuously variable transmission and/or any other suitable mechanism.
In the example illustrated, the gear portion 2404 is implemented as an internal geared hub 2405. The internal geared hub 2405 is a mechanism with multiple gear-ratios that are enclosed inside the shell 2402 of the hub 2302. Internal geared hubs are known to the person of skill in the art and as such are not discussed in detail in this document. The internal geared hub 2405 may be implemented as a three (3) speed to fourteen (14) speeds, or any other suitable speed lower than three (3) or higher than fourteen (14), or as a continuously variable transmission hub.
In a specific and non-limiting example, the internal geared hub 2405 has three gears, a first gear, a second gear and a third gear. In this specific and non-limiting example, the internal geared hub 2405 is implemented with planetary or epicyclic gears. The gears are sealed within the shell 2402 of the hub 2405. By way of a non-limiting example, the first gear may be a low gear, in which a sprocket drives an annulus and a planet carrier drives a hub, giving a gear reduction. The second gear may be a middle gear, in which a sprocket drives the hub directly. The third gear may be a high gear, in which the sprocket drives the planet carrier and the annulus drives the hub, resulting in a gear increase. It is appreciated that the number of gears may be any suitable number and may be more or less than three in other embodiments.
A shifting mechanism 2204 is provided to shift or change between the different gears to select a gear ratio. The shifting mechanism typically depends on the type of hub and/or gears used and any suitable shifting mechanism 2204 may be used.
A belt (e.g. a carbon fiber-based belt) or chain 2308 is attached to a crankset or chainset 2309, such that reciprocating motion of the cyclist's legs is converted into rotational motion used to drive the belt or chain 2308. The belt or chain 2308 is also attached to the hub 2302 such that when the belt or chain 2308 is driven the rear wheel 2301 turns. Depending on the gear that bicycle is in (e.g., gear ratio) and the cadence (e.g., the rate at which the cyclist pedals), this determines the rate at which the wheel 2301 turns.
In some embodiments, a continuously variable transmission may be used as the internal geared hub 2405. The continuously variable transmission may also be known as a single speed or gearless transmission. The continuously variable transmission may be implemented using NuVinci™ continuously variable transmission available from Fallbrook Technologies. The continuously variable transmission is a transmission that may possible change seamlessly though an infinite number of effective gear ratios between a maximum and minimum value.
In some embodiments, such as where a sprocket, a set of sprockets, a cogset or cluster is use, a derailleur mechanism may be used as the shifting mechanism with a chain driven transmission. While in other cases, where a belt driven transmission is used, an internal geared hub may be used. It is appreciated that a belt driven bicycle is a chainless bicycle that uses a toothed synchronous belt 2308 to transmit power from the pedals to the wheel.
Bicycle wheels, hubs, gears, internal geared hub, shifting mechanism, belts, chains, crankset, chainset, continuously variable transmission and various other parts of the bicycle drivetrain are known in the art and are commercially available from many manufactures. The example bicycle wheels, hubs, gears, internal geared hub, shifting mechanism, belts, chains, crankset, chainset continuously variable transmission and various other parts of the bicycle drivetrain are for illustration purposes and any other suitable bicycle wheels, hubs, gears, internal geared hub, shifting mechanism, belts, chains, crankset, chainset continuously variable transmission and various other parts of the bicycle drivetrain may be used in accordance with this aspect of the disclosure.
Referring back to
Continuing with the specific and non-limiting example of the internal geared hub 2405 having three gears, the control signal sent by the electronic device 300i to the actuator 2202 may be a control signal indicating the specific gear to put the internal geared hub 2405 in. For instance, the electronic device 300i may send a first control signal to indicate to the actuator 2202 to put the bicycle 102i into the first gear, a second control signal to indicate to the actuator 2202 to put the bicycle 102i into the second gear and a third control signal to indicate to the actuator 2202 to put the bicycle 102i into the third gear. Although in this example three control signals are used as there are three gears, it other embodiments the number of control signals may be more or less than three, and any suitable number of control signals may be used (e.g., the number of control signals may correspond to the number of gears in the internal geared hub 2405). In other cases, the control signal sent by the electronic device 300i to the actuator 2202 may be a control signal indicating an increment or decrement in a gear in the internal geared hub 2405.
In the cases where the internal geared hub 2405 is a continuously variable transmission is used, the control signal sent by the electronic device 300i to the actuator 2202 may be a control signal indicating an increment or decrement of the effective gear ratio and an amount of increment or decrement of the effective gear ratio.
In the cases where a derailleur mechanism is used as the shifting mechanism 2204, the control signal to the actuator 2202 may be a control signal that indicates an increment of decrement to the current sprocket of the cogset or cluster that the chain 2308 is in or may be a control signal that indicates the specific sprocket of the cogset or cluster to put the chain 2308 in.
The adjustment of the gear ratio of the bicycle 102i may take place automatically based on bicycle inertia data, riding pattern data and/or user data without direct mechanical control by the cyclist of the bicycle 102i.
In some embodiments, the sensors 308 obtain information which is processed by the electronic device 300i to then determine the gear ratio to put the bicycle 102i in or an increment or decrement of the gear ratio and the amount of the increment or decrement. More specifically, the sensors 308 may obtain bicycle inertia data which can be processed by the processor 302 of the electronic device 300i to determine a gear ratio of the gear portion 2404 (e.g., the internal geared hub 2405) or an increment or decrement of the gear ratio and the amount of the increment or decrement. Based on the processing by the processor 302 the electronic device 300i may send a control signal to instruct the actuator 2202 to either increase or decrease the gear or gear ratio and the amount of the increase or decrease, as discussed elsewhere in this document.
The control signal determined by the processor 302 may be based off of one or more of the following data parameters, referred to above as inertia data: elevation data, orientation in space data (e.g. inclination), speed data, linear acceleration data, cadence, position (e.g., longitude and latitude and/or elevation) or any suitable data parameter. For instance, elevation data may be obtained through the accelerometer, gyroscope, barometer and/or magnetometer; orientation in space data may be obtained from the gyroscope, accelerometer and/or magnetometer; speed data may be obtained from the speedometer; linear acceleration data may be obtained from the accelerometer and altitude may be obtained from the barometer.
In the cases where the electronic device 300i is connected to the data network 106 and the Internet, the data parameters may also include weather data, such as wind speeds and temperatures or any other suitable weather data. The weather data may be obtained from public weather servers (e.g., Weather-Network). In some cases, the obtained weather data may be cross-referenced by the processor 302 with the data from the barometer.
In some embodiments, riding pattern data may be obtained and processed by the electronic device 300i to then determine the gear ratio to put the bicycle 102i in or a direction of increment or decrement of the gear ratio and the amount of the increment or decrement. The riding pattern data may include: previous speed at various inclination/declination; speed after certain duration of riding (e.g., when the cyclist gets tired); preferred cadence and cruising speed, which may be calculated through statistical averages obtained from speed patterns. In other words, the riding pattern data can include a plurality of time-sequenced samples of the above-mentioned inertia data. The riding pattern data can also include, corresponding to each time-sequenced sample of inertia data, a current gear ratio. The riding pattern data can also include an indication of whether each sample gear ratio was controlled manually by the operator of bicycle 102 or automatically (e.g. by processor 302).
In the cases where the electronic device 300i is connected to the data network 106 and the Internet, the riding pattern data may include patterns based on traffic (congestion times/road closures) and patterns based on topography.
In some embodiments, user data may be obtained and processed by the electronic device 300i, in combination with the inertia data and/or riding pattern data, to then determine the gear ratio to put the bicycle 102i in or an increment or decrement of the gear ratio and the amount of the increment or decrement. The user data may include age, gender, weight, height, or any other suitable information about the current user of the bicycle 102i.
It is appreciated that the adjustment of the gear ratio of the bicycle 102i may take place automatically based on bicycle inertia data, riding pattern data and user data, where the inertia data, riding pattern data and user data are available; however, where one or more of the inertia data, riding pattern data and user data is unavailable, the adjustment of the gear ratio of the bicycle 102i may take place automatically based on the available data.
It is also appreciated that in this other aspect of this disclosure, the communication module 306 may be omitted in some implementations. It is also appreciated that in this other aspect of this disclosure, that the adjustment of the gear ratio of the bicycle 102i may take place automatically based on bicycle inertia data and/or riding pattern data without the electronic device 300i being connected directly or indirectly to the data network 106.
A specific and non-limiting example will now be presented of how the gear ratio of the bicycle 102i may be adjusted automatically based on bicycle inertia data and/or riding pattern data, without direct control by the cyclist of the bicycle 102i, when the electronic device 300i of the bicycle 102i is either is not connected to the data network 106 or where the electronic device 300i does not have a communication module 306.
In this example, initially the control signals for shifting the gear/gear ratio is based solely on real-time inertia data. Then as cyclist continues to use the bicycle 102i, riding pattern data may be recorded in the memory 304 of the electronic device 300i and then may be used in determining the signals for shifting the gear/gear ratio.
By way of example, if the obtained inertia data at step 2602 indicates that orientation in space of the bicycle 102i suggests that the bicycle 102i is currently going up an incline, a reduction in speed and/or linear deceleration is occurring, then at step 2604 it may be determined that the bicycle 102i should be put into a lower gear (that is, a lower gear ratio).
By way of another example, if the obtained inertia data at step 2602 indicates that orientation in space of the bicycle 102i suggests that the bicycle 102i is currently going down a decline, an increase in speed and/or linear acceleration is occurring, then at step 2604 it may be determined that the bicycle 102i should be put into a higher gear (that is, a higher gear ratio).
After or during the process 2600, the electronic device 300i may also store in the memory 304 aspects of the inertia data to create riding pattern data. After a certain amount of inertia data is obtained the electronic device 300i may process this inertia data to create riding pattern data. Then as the process 2600 repeats, which may be at a set interval stored in the memory 304, the riding pattern data can then be taken into account in future iteration of the process 2600.
The interval at which the process 2600 repeats, may be any suitable time interval. In some cases the interval is every millisecond, several milliseconds, second, several seconds and possibly a minute or more.
By way of example, once riding pattern data is available and considering the process 2600, if the obtained inertia data at step 2602 indicates that orientation in space of the bicycle 102i suggests that the bicycle 102i is currently going down a declination and at step 2602 the obtained riding pattern data indicates the cyclists speed at previous declinations, then at step 2604 it may be determined that the bicycle 102i should be put into a different gear to adjust for the difference in current speed and previous declination speeds.
By way of example, once riding pattern data is available and considering the process 2600, if the obtained inertia data at step 2602 indicates that orientation in space of the bicycle 102i suggests that the bicycle 102i is currently going up an inclination and at step 2602 the obtained riding pattern data indicates the cyclists speed at previous inclinations, then at step 2604 it may be determined that the bicycle 102i should be put into a different gear to adjust for the difference in current speed and previous inclination speeds.
As a further example, a gear ratio (or an adjustment to the current gear ratio) may be selected by processor 302 based on inertia data by comparing the current cadence (e.g. revolutions per minute of chainring 2309) to a target cadence (e.g. 70 rpm). Based on the difference between the current cadence and the target cadence, processor 302 can select a new gear ratio. The difference between the new gear ratio selected and the current gear ratio can, for example, be proportional to the difference between the current cadence and the target cadence. Thus, if the current cadence is lower than the target cadence, a new gear ratio can be selected by processor 302 that is lower than the current gear ratio.
In some embodiments, the target cadence mentioned above can be derived (either by processor 302, or by server 108 and transmitted to processor 302) from the riding pattern data. For example, processor 302 can determine or receive (e.g. from server 108) an average cadence from the riding pattern data, and set that average cadence as the above-mentioned target. In further embodiments, a plurality of average cadences can be selected and set as a plurality of target cadences. For example, processor 302 can calculate or receive an average cadence associated with each of a plurality of inclinations (e.g. an average cadence for inclinations of zero to two percent, and a second average cadence for inclinations greater than two percent). The selection of gear ratios can then be performed by processor 302 by selecting one of the target cadences based on the current inclination, and comparing the current cadence to the selected target cadence.
It is appreciated that if the gear portion 2404 of the hub 2302 is implemented as an internal geared hub 2405 that is a continuously variable transmission (or another suitable device) that at steps 2604 and 2606 then a control signal may continuously (e.g., at a very frequent interval) be send to the actuator 2202. It is also appreciated that in this case the control signal may indicate the direction of change to the gear ratio and the amount of change to the gear ratio.
Different gear ratios are appropriate for different people and styles of cycling and as such it may be desirable for the electronic device 300i to have information about the user when making a determination of the gear ratio of the bicycle 102i.
In some embodiments, therefore, processor 302 can implement variable shifting behaviour based on which mobile device (e.g. device 2902) is currently connected to electronic device 300. Different mobile devices are authorized to obtain riding pattern data from server 108 for different users, and thus electronic device 300 can set different cadence targets (as discussed earlier) based on what riding pattern data is available via mobile device 2902.
The mobile device 2902 may communicate with the electronic device 300i via a communication module 2906 in the mobile device 2902 and the communication module 306 in electronic device 300i. The communication module 2906 may include one or more modules for communicating with third party device using a Wi-Fi protocol (e.g., IEEE 802.11 protocol), Bluetooth protocol, cellular network protocol(s) (e.g., GSM, AMPS, GPRS, CDMA, EV-DO, EDGE 3GSM, DECT, IS-136/TDMA, iDen, LTE or any other suitable cellular protocol), ZigBee protocol (e.g., IEEE 802.15 protocol), protocols operating in the 900 MHz, 2.4 GHz, 5.6 GHz ranges, or any other suitable protocol or any combination thereof. The communication module 2906 in the mobile device 2902 and the communication module may be any suitable communication modules. In some implementations, the communication module 2904 in the mobile device 2902 and the communication module 306 in electronic device 300i are Bluetooth communication modules. The communication module 2906 in the mobile device 2902 may communicate with the server 108 over a cellular and/or data network 106″.
A specific and non-limiting example will now be presented of how the gear ratio of the bicycle 102i may be adjusted automatically based on bicycle inertia data from the sensors 308 and riding pattern data and/or user data (if available), without direct mechanical control of the gears by the cyclist of the bicycle 102i. The user data may be obtained by the mobile device 2902 from the server 108 via the network 106″ and then provided to the electronic device 300i.
In this example, initially the control signals for shifting the gear/gear ratio is based on real-time inertia data from the sensors 308 and the user data obtained from the server 108. Then as cyclist continues to use the bicycle 102i, riding pattern data may be transmitted from the electronic device 300i via the mobile device 2902 over the network 106 to the server 108.
By way of example, if the obtained inertia data at step 2802 indicates that orientation in space of the bicycle 102i suggests that the bicycle 102i is currently going up an inclination, a reduction in speed and/or linear deceleration is occurring, then at step 2604 it may be determined that the bicycle 102i should be put into a lower gear.
By way of another example, if the obtained inertia data at step 2802 indicates that orientation in space of the bicycle 102i suggests that the bicycle 102i is currently going down a declination, an increase in speed and/or linear acceleration is occurring, then at step 2604 it may be determined that the bicycle 102i should be put into a higher gear.
In these examples, the amount of the adjustment to the change in the gear may be determined based on the orientation in space of the bicycle 102i, the speed and/or linear acceleration and the user data. For example, a user with a tall height and/or high weight may be given a different gear ratio than a user with a short height and/or low weight for the same orientation in space of the bicycle 102i, same speed and/or same linear acceleration.
After or during the process 2800, the electronic device 300i may transmit via the mobile device 2902 over the network 106 to the server 108 some or all of the inertia data to create riding pattern data associated with the user in the user's account. Then as the process 2800 repeats, which may be at a set interval stored in the memory 304, the riding pattern data can then be taken into account in future iteration of the process 2800.
The interval at which the process 2800 repeats, may be any suitable time interval. In some cases the interval is every millisecond, several milliseconds, second, several seconds and possibly a minute or more.
Once the server 108 has logged a certain number of data points of inertial data, the server 108 may process the inertial data to create the above-mentioned riding pattern data for the specific user. The riding pattern data for the user can then be stored in the computer readable memory 404 of the server 108. The riding pattern data for the user can then be transmitted from the server 108 to the mobile device 2902 and transmitted to the electronic device 300i such that riding pattern data can be stored in the computer readable memory 304 and then accessed by electronic device 300i in determining the gear ratio or determining an increment or decrement of the gear ratio and the amount of the increment or decrement
By way of example, once riding pattern data is available and considering the process 2800, if the obtained inertia data at step 2802 indicates that orientation in space of the bicycle 102i suggests that the bicycle 102i is currently going down a declination and at step 2802 the obtained riding pattern data indicates the cyclists speed at previous declinations, then at step 2604 it may be determined that the bicycle 102i should be put into a different gear to adjust for the difference in current speed and previous declination speeds.
By way of example, once riding pattern data is available and considering the process 2800, if the obtained inertia data at step 2802 indicates that orientation in space of the bicycle 102i suggests that the bicycle 102i is currently going up an inclination and at step 2802 the obtained riding pattern data indicates the cyclists speed at previous inclinations, then at step 2604 it may be determined that the bicycle 102i should be put into a different gear to adjust for the difference in current speed and previous inclination speeds.
It is appreciated that if the gear portion 2404 of the hub 2302 is implemented as an internal geared hub 2405 that is a continuously variable transmission (or another suitable device) that at steps 2804 and 2806, then a control signal may continuously (e.g., at a very frequent interval) be send to the actuator 2202.
It is appreciated that the server may also take in to account the user data and/or the riding pattern of the user when determining the shifting command.
It is appreciated that adaptive shifting may provide for the actuator 2002 on the bicycle hub 2302, under the control of electronic device 300i to automatically adjust gear ratios without a mechanical adjustment by the rider of the bicycle 102i. The adaptive adjustment or smart-shifting may be based on sensor data (e.g., inertia data), user profile information, and/or riding pattern data, as discussed above.
It is also appreciated that the riding pattern data may be analyzed by the server 108 and then transmitted to the electronic device 300i via the mobile device 2902. Then, the electronic device 300i may automatically control actuator 2202 based on the riding pattern data to take into account the user's shifting preference, as discussed earlier.
It is also appreciated that the sensors 308 may also send data (e.g., inertia data) to the server 108 via the mobile device 2902 and the network 106″ such that sent data (e.g., inertia data) is processed by the server 108. Then the server 108 may transmit back to electronic device 300i the shifting command (e.g., the gear ratio that the bicycle 102i should be put in) and the electronic device 300i generates the control signal based on the shifting command received from the server 108 and may take into account the user's shifting preference.
The interface 3002 may displays a finite selection of gear ratios, manually selectable by operation of twist shifter 3006. For continuously variable transmissions, display 3002 need not present a finite selection of gear ratios. Instead, display 3002 can present a continuous scale encompassing a large or infinite number of selectable gear ratios. The interface 3002 may also have an “Adaptive” option (also selectable by twist shifter 3006) that may link to the user's riding patterns which may be obtained from their user profile and the bicycles real-time inertia data as mentioned elsewhere in this document. In other words, the “adaptive” option is selectable to transition from manual shifting to automatic shifting according to the processes discussed above.
It is appreciated that such a grip 3004 may provide a secondary user-interface for the user as an alternative to the user using a mobile device 2902. In other words, such a configuration may provide an alternative to using a mobile interfacing while riding a bicycle.
In the example illustrated, the display 3002 is a digital display and the shifter 3006 when rotated causes a digital signal to be sent to the electronic device 300i to indicate a desired gear ratio. In other cases, the movement of the shifter 3006 commands the digital interface up or down. Yet in other case the shifter 3006 may be omitted, if the display 3002 is a touch-screen or other suitable display.
In some cases, in may be desirable for the user to not have user account associated with the bicycle, when the bicycle 102i is in use. For example, if the owner of the bicycle 102i is borrowed to a third-party, the owner of the bicycle 102i may not want the third-parties' user data to influence owner's future usage of the bicycle 102i and vice versa.
Instead of the user login into the user profile, setting the user's shifting preference, and the server 108 obtain the usage data (e.g., inertia data), a third-party may use the bicycle 102i without the server 108 obtaining, storing and processing the usage data (e.g., inertia data) to create or update the riding pattern data for the user. In other words, the default setting of the bicycle 102i when the bicycle is not connected to the mobile device 2902 is to not obtain, storing and processing the usage data (e.g., inertia data) to create or update the riding pattern data for the user.
In other cases, the user may login into the user profile and set the bicycle to “guest mode” such that no usage data (e.g., inertia data) is obtained, stored and process.
In some cases, the GPS sensor 308 of the electronic device 300i may obtain coordinate or location information (e.g., longitude and latitude) which may then be communicated to the server 108. The server 108 may then provide gear information based on the current coordinate information. For example, the for a first specific location the computer readable memory 404 of the server 108 may store an indication that the bicycle should be put into the first gear, while for a second specific location the computer readable memory 404 of the server 108 may store an indication that the bicycle should be put into the second gear.
In other cases, the electronic device 300i stores a mapping in the database in the computer readable memory 304 of the electronic device 300i of the location information (e.g., longitude and latitude) with a gear setting. In this case, the GPS of the electronic device 300i provides location information (e.g., longitude and latitude) which is then looked-up in the database of the electronic device 300i to obtain the information regarding which gear to put the bicycle 102i in. Then, the electronic device 300i may send a control signal to the actuation device to indicate to the actuation device which gear to put the bicycle 102i in.
The shifting device 3101 can be placed in similar positions throughout the bicycle much like electronic device 300i. In some cases, the shifting device 3101 is compartmentalized within in the hub 2302 of the bicycle 102i. In other cases, the shifting device 3101 is not compartmentalized within the hub 2302 but is located within another part of the bicycle 102i and is connected with the hub 2302 via one or more wires.
It is appreciated that in other embodiments, the shifting device 3101 is compartmentalized within other parts of the bicycle 102i. For example, shifting device 3101 may be placed in the down-tube, steer tube and the rear-dropout. It is appreciated that by placing the smart-hub in the rear-dropout may facilitate a parallel connection with the actuator 2202 with minimal wire-routing.
If the bicycle is already equipped with a dynamo, usually placed at on the front wheel hub, then the battery 312 may be charged through it. In other cases a charging outlet located on the shifting device 3101 may allow for the shifting device 3101 to be connected either through a micro-usb or any other power-transferring medium to recharge the battery 312 compartmentalized within the shifting device 3101.
A theft deterrence feature is provided such that when the bicycle 102i receives an indication that it is stolen (as discussed elsewhere in this document), the electronic device 300i may be instructed directly or indirectly via the server 108 or automatically to place the bicycle 102i in to the lowest and/or highest available gear ratio. In other words, the actuator 2202 may be disabled possibly causing the bicycle to be difficult to use.
