Description

TECHNICAL FIELD

Certain disclosed embodiments relate to the field of portable locking devices.

BACKGROUND

Existing portable locking devices, such as padlocks, are generally limited to operation with a shackle that is permanently connected at one end to the lock body, or with one specific type of shackle element. Existing cables and cable-like shackle assemblies are equipped with only rudimentary sensors for monitoring and detecting the condition of the cable. Padlocks with wireless capability typically report condition using a simple, binary message (for example, Lock OK or Lock Not OK) and lack the capacity to transmit or receive signals in remote areas.

Thus, there is need in the art for improved portable locking devices.

FIG. 1B is a block diagram illustrating the functional elements of a server 11, such as the one shown in FIG. 1A. The server 11 includes but is not limited to a workstation, desktop computer, PC, and any of a variety of mobile computer devices.

Generally, in terms of hardware architecture, as shown in FIG. 1B, the server 11 may include a processor 41, memory 42, and one or more input and/or output (I/O) devices (or peripherals) that are communicatively coupled via a local interface 43. The local interface 43 may be, for example, but is not limited to, one or more buses or other wired or wireless connections, as is known in the art. The local interface 43 may have additional elements to facilitate communications, which are omitted for simplicity, such as controllers, buffers (caches), drivers, repeaters, and receivers. Moreover, the local interface 43 may include address, control, and/or data connections to enable appropriate communications among the aforementioned components.

The processor 41 is a hardware device for executing software that can be stored in memory 42. The processor 41 can be virtually any custom-made or commercially available processor, a central processing unit (CPU), data signal processor (DSP), or an auxiliary processor, among several processors associated with the server 11; and a semiconductor based microprocessor (in the form of a microchip) or a macro-processor. Examples of suitable commercially available microprocessors include but are not limited to: an 80×86, Pentium series, or later-series microprocessor from Intel Corporation, a PowerPC microprocessor from IBM, a SPARC microprocessor from Oracle Corporation (formerly Sun Microsystems, Inc.), a PA-RISC series microprocessor from Hewlett-Packard Company, or a 68000 or 88000 series microprocessor from Freescale Semiconductor, Inc. (formerly Motorola, Inc.).

The memory 42 may include any one or combination of volatile memory elements (e.g., random access memory (RAM, such as dynamic random access memory (DRAM), static random access memory (SRAM), etc.)) and nonvolatile memory elements (e.g., ROM, erasable programmable read only memory (EPROM), electronically erasable programmable read only memory (EEPROM), programmable read only memory (PROM), tape, compact disc read only memory (CD-ROM), disk, diskette, cartridge, cassette or the like, etc.). Moreover, the memory 42 may incorporate electronic, magnetic, optical, and/or other types of storage media. Note that the memory 42 can have a distributed architecture, where various components are situated remote from one another, but can be accessed by the processor 41.

The software in memory 42 may include one or more separate programs, each of which comprises an ordered listing of executable instructions for implementing logical functions. In the example illustrated in FIG. 1B, the software in the memory 42 includes a suitable operating system (O/S) 49 and one or more programs on the accounts system 100.

A non-exhaustive list of examples of a commercially available and suitable operating system 49 includes: (a) a Windows operating system available from Microsoft Corporation; (b) a Netware operating system available from Novell, Inc.; (c) a Macintosh operating system available from Apple Computer, Inc.; (d) a UNIX operating system, which is available for purchase from many vendors, such as the Hewlett-Packard Company, Sun Microsystems, Inc., and AT&T Corporation; (e) a LINUX operating system, which is freeware that is readily available on the Internet; (f) a run time Vxworks operating system from WindRiver Systems, Inc.; or (g) an appliance-based operating system, such as that implemented in handheld computers or personal data assistants (PDAs) (e.g., Symbian OS available from Symbian, Inc., PalmOS available from Palm Computing, Inc., and Windows CE available from Microsoft Corporation). The operating system 49 essentially controls the execution of other computer programs, such as the accounts system 100, and provides scheduling, input-output control, file and data management, memory management, and communication control and related services.

The accounts system 100 may be a source program, an executable program (object code), a script, or any other entity comprising a set of instructions to be performed. For embodiments in which it is a source program, then the program is usually translated via a compiler, assembler, interpreter, or the like, which may or may not be included within the memory 42, so as to operate properly in connection with the operating system 49. Moreover, the accounts system 100 may be written as (a) an object-oriented programming language, which has classes of data and methods, or (b) a procedure programming language, which has routines, subroutines, and/or functions, for example but not limited to, C, C #, Pascal, BASIC, API calls, HTML, XHTML, XML, ASP scripts, FORTRAN, COBOL, Perl, Java, ADA, .NET, and the like.

The input/output (I/O) devices may include any of a variety of input devices, including but not limited to a mouse 44, keyboard 45, scanner (not shown), microphone (not shown), touch-sensitive screen (on the display 46), a gesture-responsive interface, and any of a variety of other input devices. Moreover, the I/O devices may also include output devices, including but not limited to a printer (not shown), the display 46, etc. Finally, the I/O devices may further include devices that communicate both inputs and outputs, including instance but not limited to a network interface controller (NIC) or a modem (modulator/demodulator) 47 (for accessing remote devices, other files, devices, systems, or a network), a radio frequency (RF) or other transceiver (not shown), a telephonic interface (not shown), a bridge (not shown), a router (not shown), etc.

If the server 11 is a PC, workstation, intelligent device, or the like, the software in the memory 42 may further include a basic input output system (BIOS) (omitted for simplicity). The BIOS is a set of essential software routines that initialize and test hardware at startup, start the operating system 49, and support the transfer of data among the hardware devices. The BIOS is stored in some type of read-only-memory, such as ROM, PROM, EPROM, EEPROM or the like, so that the BIOS can be executed when the server 11 is activated.

When the server 11 is in operation, the processor 41 is configured to execute software stored within the memory 42, to communicate data to and from the memory 42, and generally to control operations of the server 11 are pursuant to the software. The accounts system 100 and the operating system 49 are read, in whole or in part, by the processor 41, perhaps buffered within the processor 41, and then executed.

The accounts system 100 may be embodied in any computer-readable medium for use by or in connection with an instruction execution system, apparatus, or device, such as a computer-based system, processor-containing system, or other system that can fetch the instructions from the instruction execution system, apparatus, or device and execute the instructions.

In the context of this document, a “computer-readable medium” includes any means that can store, communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device. The computer readable medium can be, for example but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, device, propagation medium, or other physical device or means that can contain or store a computer program for use by or in connection with a computer related system or method. More specific examples of a computer-readable medium, in a non-exhaustive list, includes the following: an electrical connection (electronic) having one or more wires, a portable computer diskette (magnetic or optical), a random access memory (RAM) (electronic), a read-only memory (ROM) (electronic), an erasable programmable read-only memory (EPROM, EEPROM, or Flash memory) (electronic), an optical fiber (optical), and a portable compact disc memory (CDROM, CD R/W) (optical). Note that the computer-readable medium could even be paper or another suitable medium, upon which the program is printed or punched (as in paper tape, punched cards, etc.), because the program can be electronically captured, via for instance optical scanning of the paper or other medium, then compiled, interpreted or otherwise processed in a suitable manner if necessary, and then stored in a computer memory.

In an alternative embodiment, the accounts system 100 may be implemented in hardware, using for example any one or a combination of the following technologies, each of which is well known in the art: one or more discrete logic circuits having logic gates for implementing logic functions upon data signals, an application specific integrated circuit (ASIC) having appropriate combinational logic gates, one or more programmable gate array (PGA), a field programmable gate array (FPGA), and the like.

FIG. 1C is a block diagram illustrating the functional elements of the one or more remote devices 15, 17-20 that facilitate access to and operation of an access system 60. As illustrated, the elements in each remote device 15, 17-20 are similar in type, function, and operation to those described with respect to the server 11 in FIG. 1B. In the embodiment shown, the access system 60 may be installed on and operated by the remote device 15, 17-20. Hereinafter, the remote devices 15, 17-20 will be referred to as mobile device 15 for the sake of brevity.

The mobile device 15 may include a processor 51, a memory 52, and one or more input and/or output (I/O) devices (or peripherals) that are communicatively coupled via a local interface 53. The I/O devices include any of a variety of input devices, including but not limited to a mouse 54, keyboard 55, a touch-sensitive screen (on the display 56), a gesture-responsive interface, and any of a variety of other input devices. The memory 52, as described herein, may include a volatile memory cache.

The access system 60 may be a source program, an executable program (object code), a script, or any other entity comprising a set of instructions to be performed. For embodiments in which the access system 60 is a source program, the program is usually translated via a compiler, assembler, interpreter, or the like, which may or may not be included within the memory 52, so as to operate properly in connection with the operating system 59. Moreover, the access system 60 may be written as (a) an object-oriented programming language, which has classes of data and methods, or (b) a procedure programming language, which has routines, subroutines, and/or functions, for example but not limited to, C, C++, C #, Pascal, BASIC, API calls, HTML, XHTML, XML, ASP scripts, FORTRAN, COBOL, Perl, Java, ADA, .NET, and the like.

Portable Lock Assemblies

Although many of the systems and methods described herein are discussed in the context of a portable locking device with a cable, the technology disclosed herein is also useful and applicable in a variety of other contexts. For example, the devices and systems described herein would be useful and applicable for all types of locks and security devices where wireless connectivity and functionality would be beneficial.

FIG. 2 is a perspective illustration of an item of personal property 150, such as a kayak, secured by the cable 235 of a lock assembly 200, according to particular embodiments. As shown, the housing 210 of the lock assembly 200 is resting on the kayak's rail and the cable 235 extends around a tree or post. In use, the lock assembly 200 can secure one (or several) items of personal property 150 using a cable 235. The cable 235 selected may be relatively long, or shorter, as selected by the user. As described herein, the lock assembly 200 is configured for use with cables 235 of different lengths, or with a solid U-shaped shackle (like that of a traditional padlock), or with other types of shackles. The cable 235 may include a sensor element 236, as shown and described herein, according to particular embodiments.

A traditional padlock has a solid U-shaped shackle and a body or housing with openings for receiving the heel and toe ends of the shackle, and for receiving a key that operates a locking mechanism inside the housing. In many padlock designs, the shackle heel is secured in the housing and may be spring-mounted. The shackle toe or free end includes a notch or recess, which engages with a locking bar to secure or lock the shackle within the housing when locked. The locking mechanism includes a keyway for receiving a key, which may turn a series of tumblers and pins for operating the lock.

Referring to FIG. 3, the lock assembly 200 of the present invention includes a housing 210 and first and second pinways 251, 252 that are sized and shaped to receive first and second shackle pins 231, 232, respectively. The lock assembly 200 may include a keyway 258 and a key, or an alternative locking assembly for securing and locking the shackle pins 231, 232 once inserted into the housing 210. For example, an alternative locking assembly may include a padlock having a shackle for insertion into and through the housing 210 at a position where it secures the shackle pins 231, 232 inside the housing 210.

Each shackle pin 231, 232 may be selectively removable from the housing 210, unlike most padlock designs. The shackle pins 231, 232 may be located on the opposing ends of a cable 235. In this aspect, the cable 235 acts as a flexible shackle. One or both shackle pins 231, 232 may include a recess that is sized and shaped to engage with a locking bar inside the housing, which is operated using a key in the keyway 258 or by using an alternative locking assembly, as described.

As shown, the housing 210 may include may include one or more slots or holes 300 for receiving straps, ropes, or other tethering devices which may be useful for carrying the lock assembly 200 or for positioning or securing it at a desired location.

The housing 210 may include one or more lamps 285 for displaying the status or condition of the lock assembly, to indicate Ready, Locked, Alarm, and the like. The lamps 285 may be light-emitting diodes (LEDs) and may be configurable by the user, including variations in color, brightness, and blink pattern. The lamps 285 may include one or more lamps positioned on one or more sides of the housing 210 in order to facilitate viewing from different perspectives.

The openings to the first and second pinways 251, 252 may be positioned on the rear face of the housing 210. According to one embodiment, the pinways 251, 252 are spaced 1.25 inches apart. The pinway openings and/or other openings on the housing 210 may be protected with a door, a flap, or other type of covering in order to protect the interior components from water and the elements. According to particular embodiments, the other openings on the housing 210 may include a power button, a charging port, and a camera.

FIG. 4 is a schematic illustration depicting the connections between and among a power supply 215 or battery, and NFC interface and antenna 299, one or more sensors, a microcontroller 220, and interfaces with one or more communications modules, according to particular disclosed embodiments. The microcontroller 220, often abbreviated uC or μC (as in the figure), is a small computer on an integrated circuit board which is used to control electronic devices. The microcontroller 220 typically includes a processor core, a memory, and programmable input/output peripherals.

The elements shown schematically in FIG. 4 are located within the housing 210 of the lock assembly 200. The power supply 215 or battery, as shown, may include a secondary or backup battery, and may be connected to the microcontroller or uC 220 which is positioned on an integrated circuit board which is labeled as the Main goLock Board. Also on the board is a charging and voltage regulator (Vreg) circuit. The charging interface may be wireless and/or may include a charging port such as a micro-USB type.

Also on the Main goLock Board, according to particular embodiments, is a BLE transceiver 290. Bluetooth Low-Energy (BLE or Bluetooth Smart) is a wireless network technology designed and marketed by the Bluetooth Special Interest Group. BLE is intended to provide a communication range similar to Classic Bluetooth but with considerably reduced power consumption and cost. The BLE transceiver 290 is configured to communicate with one or more remote or mobile devices 15, 17-20 including a smart phone 20 or tablet computer 18, as described herein. The microcontroller 220 includes a memory and a processor core capable of executing a number of commands and responses.

Instead of (or in addition to) the BLE transceiver 290, the system may include one or more other communications modules, as shown in FIG. 4, including a cellular modular, a WiFi module, a sub-gigahertz radio, and a locator module (for example, GPS or GLONASS). The system may also include UART, SPi, i2C, or other types of interfaces, as shown.

The sensor assembly 240 may include sensors to detect whether a pin has been inserted into one of the pinways, according to particular embodiments. In this aspect, the sensors may include a first pinway sensor (positioned to sense the presence or absence of a first shackle phi 231 in the first pinway 251, as illustrated in FIG. 3) and a second pinway sensor (positioned to sense the presence or absence of a second shackle pin 232 in the second pinway 252).

The sensor assembly 240 may also include a cable type sensor 245 for detecting the type of cable that is inserted, including its length (as described herein). The sensor assembly 240 may also include a cable status sensor 246 for detecting the status, integrity, or condition of the cable. For example, the cable status sensor 246 may be configured to sense a cable interrupt event, such as a cable break or cut, and to sense cable tampering (a shock or insult to the cable without necessarily breaking it). The sensor assembly 240 may also include a variety of other types of electromechanical sensors for detecting temperature, shock, motion, and other conditions. The sensor assembly 240 may also include a camera.

Cable Type and Status:

The cable assembly 230, according to particular embodiments, includes a cable 235, first and second shackle pins 231, 232 at the cable ends, and a sensor element 236 (as illustrated schematically in FIG. 2) such as a resistive wire, carbon filaments, a coaxial conductor, or the like. The sensor element 236 may be positioned along all or part of the length of the cable 235.

In use, the sensor element 236 enables the cable type sensor 245 to sense and detect the type of cable currently in use, including its type (cord, wire, plastic-coated cable, for example) and its length. The cable type and length may be sensed, transmitted, registered, and stored on the access system 60 (mobile app) which is running on a mobile device 15. In this aspect, a specific cable 235 may be associated with a particular lock assembly 200. Any change in the cable type or length will trigger an alarm status.

In use, the sensor element 236 enables the cable status sensor 246 to sense and detect the status, integrity, or condition of the cable. For example, a sensor element 236 such as a coaxial conductor running along the entire length of the cable 235 would sense a cable interrupt event, including a cable break or cut. The sensor element 236 may also be configured to sense cable tampering, such as a shock or insult to the cable that does not completely break it.

FIG. 5 is a flow chart depicting the some of the steps in controlling the power and wake status for the lock assembly 200, according to particular embodiments. Starting with the Power On event 401, the Initialize routine 402 may include setup steps, verification, and communications routines, as shown, before the system enters Run status 403. As shown, the system may enter a sleep or Hibernate mode 404 during periods of inactive use, while of course maintaining sensor vigilance for detecting any Interrupt condition 405.

Setup and Operation

FIG. 6 is an illustration of the system, according to particular embodiments, which may include a mobile device 15 such as a smart phone, a server 11, and one or more lock assemblies 200. As shown, the three elements—the mobile device 15, the server 11, and the one or more lock assemblies 200—may be in communication with one another, over a network such as the Internet, as described herein. A mobile application, referred to herein as the access system 60, may be installed on a user's mobile device 15. A database 12 may be installed on the server 11, as shown. The server 11 may be a cloud-based server configured to connect via the Internet, as described herein.

The lock assembly 200 may include a battery, as described herein. The battery may be disabled during the manufacturing process in order to maintain its integrity during packaging, shipment, and transit. Once enabled, the battery provides electric power to components in the lock assembly 200 such as the microcontroller 220 and the BLE transceiver 290, shown in FIG. 4. The BLE transceiver 290 may be configured to communicate over a network (such as the Internet) with both the mobile device 15 and with the remote server 11.

The access system 60 or mobile app may include a user interface for creating a new account, for sensing and pairing with a particular lock assembly 200, and for registering user information and information about the lock assembly 200. After creating a new account, the mobile device 15 may be configured to verify the account, confirm that a user account does not already exist, and open a new account on the server 11. The access system 60 may be configured to send the data about the new account to the server 11.

Next, the access system 60 may send a signal to the lock assembly 200 that contains instructions to turn on or otherwise activate the onboard BLE transceiver 290. The BLE transceiver 290 may be configured to search for nearby lock assemblies 200 that are not already paired with the access system 60 on the mobile device 15. As described herein, the BLE transceiver 290 supports a two-way Bluetooth communication between the access system 60 and the lock assembly 200 in order to enable a pairing process. For example, the access system 60 may display to the user an identifier associated with a particular lock assembly 200 (such as a serial number) and start the process of pairing the lock assembly 200 with the access system 60. Once pairing is completed, the user may have the option of assigning a custom name for the lock assembly 200 (such as “Kayak” as illustrated in FIG. 7) and the access system 60 may send data and information related to the pairing to the server 11 for registration and storage in the database 12.

The access system 60 may be configured to send a request to the lock assembly 200 and thereby retrieve the current configuration and status, which can then be presented on the display 56 for the mobile device 15.

The access system 60 may include a menu of options for the user, including an Arm command associated with each of the registered lock assemblies 200. If the mobile device 15 is within Bluetooth range of the lock assembly 200, the Arm command may be sent via Bluetooth signal. If the mobile device 15 is not within Bluetooth range, the Arm command may be sent over a network such as the Internet to the server 11, and the server 11 will relay the Arm command to the lock assembly 200. Then, in turn, a confirmation from the lock assembly 200 will be relayed by the server 11 to the mobile device 15.

When an Alarm condition arises for the lock assembly 200, the lock assembly 200 may (1) sound a local alarm, (2) broadcast an alarm message via Bluetooth in the event the mobile device 15 is within range, (3) transmit an alarm message to the mobile device 15, and/or (4) transmit an alarm message to the server 11. The server 11 may send the alarm message via push notification to the mobile device 15. The alarm message may include the nature or detected cause of the alarm condition—for example, a cable break, cable pin removal, or cable insult.

The lock assembly 200 may also be configured to sound a local alarm. The local alarm may be configurable for type (audible siren, tactile vibration, LED display, for example) and for characteristic (pattern, tone, volume, duration, repetitions, and the like). The local alarm, for example, may include flashing and/or changing the color of the lamps 285 on the housing 210.

In response to the incoming alarm, the access system 60 on the mobile device 15 may be configured to silence or otherwise react to the alarm on the mobile device 15. The mobile device 15 may be configured to silence the local alarm at the lock assembly 200, without disarming the locking mechanism.

During normal operation, the access system 60 on the mobile device 15 may be configured to occasionally poll the lock assembly 200 in order to retrieve operational and status information, including such data as battery level, signal strength, cable status, and the like. The data may be displayed on the mobile device 15, as illustrated in FIG. 8. The polling request may be relayed by the server 11 to the lock assembly 200; the server 11 in turn will relay the information back to the mobile device 15. As shown in FIG. 5, the microcontroller 220 may be configured to include various operational modes, including Initialize, Run, Interrupt, Sleep, and Hibernate. As shown, receiving a Check State or other command received from the mobile device 15 (or from the server 11) will temporarily stop the Hibernate mode and/or Sleep mode and the microcontroller 220 will process the incoming commands) and send the appropriate response.

The access system 60 on the mobile device 15 may be configured to register a number of contacts, some of whom are authorized using the access system 60 to access and open one or more select lock assemblies 200. A number of different lock assemblies 200 may be monitored and controlled using the access system 60 on the mobile device 15, as illustrated in a screen capture in FIG. 9.

An authorized contact may install the mobile app (access system 60) on their mobile device 15 and thereby interact with the user. In this aspect, the user may select and authorize certain contacts to access and use one or more of the select lock assemblies 200. For example, the user may authorize Adam to access and open the “Kayak” lock assembly 200; and may authorize Betty to access and open the “Kayak” and the “Bicycle” lock assemblies 200 using the access system 60. The access system 60 may be configured to include ready access to the telephone and text-messaging systems on the mobile device 15 so that the user may communicate with a selected contact, such Adam or Betty, for example, who may be near an item of locked personal property 150 and seeking access to the lock assembly 200.

The access system 60 on the mobile device 15 facilitates remote control and operation of the lock assembly 200 by a user, including situations where a contact or another person is near the lock assembly 200. For example, the user may use the mobile device 15 to send a Disarm signal to unlock a selected lock assembly 200 so that the local person can access and use the item. After the Disarm signal is received and the lock assembly 200 is unlocked, the local person can remove one or both shackle pins 231, 232 (which opens or releases the cable assembly 230) and use the property 150. In another aspect, the lock assembly 200 may also include a shackle pin ejector 260 that is configured to selectively and forcefully eject one or both shackle pins 231, 232 of the cable assembly 230.

Mesh of Nodes in a Network:

In another aspect, one or more lock assemblies 200 may be used in a network or mesh for the purpose of communicating with one or more selected mobile devices 15 and/or with one or more remote servers 11. For example, a user (or set of users) may have a number of lock assemblies 200 deployed in a particular area, which may be in remote or wilderness areas. The local computer or microcontroller 220 on each lock assembly 200 may be configured to communicate with other lock assemblies 200 (selected and identified through an interface, or selected by default to participate in the mesh) so that a superset of lock assemblies 200 together may act as a communication network. The network or mesh 113 may be secured and limited to lock assemblies 200 only, excluding participation by other wireless devices. In use, the network or mesh 113 of lock assemblies 200 will facilitate communication, across remote wilderness or other wide areas, which would otherwise be more difficult or impossible. In this aspect, the lock assemblies 200 are configured to act as nodes in the mesh so that signals, including alarm messages, can be relayed among and between participating elements in the mesh, to further insure that the user will receive current information and data on his or her mobile device 15.
