Description

RELATED FIELD

Various embodiments relate generally to accessory busses for electronic devices. More specifically, various embodiments relate to accessory busses capable of wirelessly coupling an accessory to an electronic device.

BACKGROUND

Many electronic devices enable users to add a new functionality or improve an existing functionality by adding an accessory. For example, video recorders (“webcams”), input devices (e.g., mice and keyboards), and external storage can easily be connected to personal computers. These accessories are typically connected to electronic devices through a wired connection (e.g., via a Universal Serial Bus (“USB”) port) or a wireless connection (e.g., via a WiFi adapter or a Bluetooth chip).

Wired connections ensure that an accessory is able to consistently receive sufficient power from the electrical device. For example, an external storage device may be configured to transfer data and receive power via a single wired connection with a USB port of the user device. However, wired connections may be undesirable from an aesthetic perspective and are often impractical in certain situations (e.g., when clear channels between the accessory and user device are not available). Wireless connections, meanwhile, may have poor connectivity and/or limited bandwidth in some scenarios, which impacts a user's ability to utilize the accessory. Moreover, wireless accessories typically require a dedicated power source that requires its own wired connection (e.g., a dedicated AC/DC adapter) or must be periodically replaced (e.g., a battery).

SUMMARY

Techniques for securely attaching an accessory to a wireless accessory bus of a user device are described herein. More specifically, the wireless accessory bus enables data to be wirelessly transmitted between the accessory and the user device when the accessory and the user device are located within close proximity to one another (e.g., when the accessory is securely attached to the wireless accessory bus). Power could also be wirelessly transferred from the user device to the accessory (or vice versa). That is, the user device could serve as the power source for the accessory.

A communication channel and/or a power transfer channel could be initiated in response to determining the accessory has been securely attached to the wireless accessory bus of the user device. In some embodiments, the accessory and the user device are magnetically affixed to one another. For example, both the accessory and the user device may include magnets that, when aligned and placed within close proximity to one another, cause the accessory to be affixed to the user device in a predetermined orientation.

The accessory typically provides the user device with a new functionality or improves an existing functionality. For example, the accessory could include a depth sensor/camera, an external storage device, a digital camera, an auxiliary power supply, a display, etc. The accessory could also be integrated into a case or cover adapted for the user device. For example, an accessory that includes an external storage device could be integrated into a case for a mobile phone, thereby providing the mobile phone with additional storage capabilities.

System Overview

FIG. 1A is a front view of a conventional user device 100 that includes a display 102 disposed within a housing 106 that protects various components (e.g., sensors, connectors, power supply) that reside within the user device 100. The housing 106 is typically composed of a protective substrate, such as metal or plastic. In some embodiments, the display 102 is touch sensitive and is configured to generate signals responsive to a user contacting the outer surface of the display 102.

The user device could include other features as well, such as a camera and a touch-sensitive button that are offset from the display 102. The camera and/or touch-sensitive button may be located within an opaque border that surrounds the display 102 and is not responsive to user interactions (i.e., is not touch sensitive). The opaque border is often used to hide the various components that reside within the user device 100.

FIG. 1B is a bottom view of the conventional user device 100 that depicts an audio port 106 and a power port 108. The audio port 106 (also referred to as an “audio jack”) is a receptacle or jack that can be used to transmit analog signals, such as audio. More specifically, the audio port 106 typically includes two, three, or four contacts that enable audio signals to be readily transmitted when an appropriate plug is inserted into the audio port 106. For example, most speakers and headphones include a plug designed for a 3.5 mm audio jack.

The power port 108 (also referred to as a “power jack”) enables the user device 100 to be physically connected directly to a power source. For example, the power port 108 could be capable of interfacing with a micro-USB adapter, a 30-pin adapter, or a proprietary bus (e.g., Apple Lightning). Together, the audio port 106 and power port 108 can enable accessories (e.g., headphones, storage devices) to be fastened directly to the conventional user device 100. However, as noted above, physical (i.e., “wired”) connections are often undesirable for both aesthetic and functional reasons.

Although FIGS. 1A-B include an illustration of a mobile phone, the techniques described herein can also be used with other electronic devices for which it is desirable to eliminate physical ports for transferring data and/or power. For example, the same techniques could be utilized with personal computers, tablets, personal digital assistants (PDAs), mobile phones, game consoles (e.g., Sony PlayStation or Microsoft Xbox), mobile gaming devices (e.g. Sony PSP or Nintendo 3DS), music players (e.g., Apple iPod Touch), wearable electronic devices (e.g., watches), network-connected (“smart”) devices (e.g., televisions), and other portable electronic devices.

FIG. 2 is a rear view of a user device 200 that includes a wireless accessory bus 202 capable of receiving an accessory. The wireless accessory bus 202 enables data and/or power to be wirelessly transferred from the user device 200 to the accessory (or vice versa) when the user device 200 and the accessory are within close proximity to one another. For example, a bi-directional communication channel may be established when the accessory is securely attached to the wireless accessory bus 202.

As shown in FIG. 2, the term “wireless accessory bus” refers generally to an area of the user device 200 that is configured to securely receive an accessory. The wireless accessory bus 202 can include one or more power transmitters 204, one or more wireless transceivers 206, and/or one or more magnets 208 (collectively referred to as the “bus components”).

Some of these bus components could be at least partially exposed. For example, the magnet(s) 208 may be exposed through opening(s) in the housing 212. Additionally or alternatively, some of these bus components could be secured within the housing 212. In such embodiments, the bus components may be selected in order to compensate for signal degradation that occurs as the data signals and/or power signals traverse through the housing 212 or a substrate laid within a break 210 in the housing 212. The substrate may be an optically-clear substrate, such as glass or plastic.

The power transmitter(s) 204 are configured to transfer power from a power supply (e.g., a battery) retained within the housing 212 to an accessory via a wired or wireless electrical coupling. For example, the power transmitter(s) 204 may include one or more electrical contacts (e.g., pin terminals) that are able to physically contact one or more electrical contacts of the accessory. As another example, the power transmitter(s) 204 may include integrated circuits (“chips”) that are able to wirelessly transmit power from the user device to the accessory. The wireless power transmitter(s) 204 may be configured to transmit power in accordance with the Qi standard developed by the Wireless Power Consortium or some other wireless power standard.

The wireless transceiver(s) 206 are communicatively coupled to one or more wireless transceivers of the accessory. For the purposes of illustration and simplification, the term “wireless transceiver” is intended to cover components able to transmit data, receive data, or both. Moreover, a single wireless transceiver could include distinct components responsible for transmitting and receiving data signals.

Upon determining an accessory has been securely attached to the wireless accessory bus 202, the wireless transceiver(s) 206 may be configured to automatically initiate a connection with the wireless transceiver(s) of the accessory. For example, if the accessory includes multiple digital cameras, image data may be received by the wireless transceiver(s) 206 from the accessory. In some embodiments, an application associated with the accessory could also be downloaded from a network-accessible environment (e.g., a digital distribution platform such as a website or an app store) and/or launched in response to determining the accessory has been securely attached to the wireless accessory bus 202.

Oftentimes, the wireless accessory bus 202 includes a fastening component that enables the accessory to be securely attached to the user device 200. Here, for example, magnet(s) 208 are arranged around the wireless accessory bus 202 so that the accessory is in a predetermined orientation when attached to the user device 200. However, other materials and components could also be used. For example, a magnetic film could be deposited on an outer or inner surface of the housing 212 or a mechanical track, clips, etc., could be affixed to the housing 212. The predetermined orientation may cause a wireless transmitter of the accessory to be aligned with, or disposed in close proximity to, the wireless transceiver(s) 206 of the user device 200.

The housing 212 also typically includes one or more breaks 210. These break(s) 210 may be necessary for permitting antenna(s) within the housing to send and receive signals or could be for stylistic/aesthetic purposes. These break(s) 210 typically include a substrate layer comprised of a non-metal material, such as glass or plastic, that allows signals to more readily pass through.

As shown in FIG. 2, the wireless accessory bus 202 could be positioned in or around one of the break(s) 210. In such embodiments, one or more light emitting diodes (LEDs) 214 may be disposed underneath the substrate layer and configured to convey information about the user device 200 and/or the accessory. For example, the LEDs 214 could illuminate when the accessory is brought near the user device 200, thereby indicating where the accessory should be attached. As another example, the LEDs 214 may be able to convey operational information, such as whether the accessory is receiving sufficient power, is able to transfer data signals to the user device, is currently available for use, etc.

FIG. 3 depicts various accessories 302a-c that are attached to user devices 300a-c that include wireless accessory busses. The accessories 302a-c are normally designed so that each accessory can be easily attached to and removed from the wireless accessory bus without modification. Moreover, a user device is normally configured to automatically establish a communication channel between the user device and the accessory and automatically begin transferring power to the accessory. Consequently, the accessory may be usable immediately or soon after attachment to the wireless accessory bus of the user device.

As described above, the accessory, the user device, or both could include fastening components (e.g., magnets or mechanical connectors) that allow the accessory and the user device to be securely and detachably connected to one another. Said another way, the accessory and the user device may be capable of being readily and repeatedly attached and detached from one another. Consequently, a user could elect to quickly utilize a series of accessories in succession by a single user device.

In some embodiments, an application associated with an accessory is initiated in response to determining the accessory has been attached to the wireless accessory bus of the user device. For example, attaching accessory 302a (a 360° camera) or accessory 302c (a multi-LED illumination source) may prompt a camera application to be invoked, while attaching accessory 302b (an external storage device) may prompt a data storage application to be invoked.

FIG. 4 includes front, side, rear views of a camera accessory 400 having multiple digital cameras 410a-b that are capable of capturing a substantially 360° field of view. The camera accessory 400 can include one or more digital cameras that are configured to capture an image and are secured within a housing 402. Images captured by the digital camera(s) typically have different characteristics than those captured by the camera of the user device. For example, the images may have a higher resolution, be 3D/stereoscopic in nature, etc. Here, for instance, multiple digital cameras 410a-b are arranged to capture an image having a substantially 360° field of view (“FOV”).

In some embodiments, the camera accessory 400 also includes an image processing module that is able to analyze and process the image data prior to transmission to the user device. For example, the image processing module may be configured to stitch images together taken by multiple distinct cameras. Alternatively, unprocessed image data could be transmitted directly to the user device for processing.

The camera accessory 400 can also include one or more power receivers 404, one or more wireless transceivers 406, and one or more magnets 408 (collectively referred to as the “accessory components”). Some of these accessory components could be at least partially exposed. For example, the magnet(s) 408 may be exposed through opening(s) in the housing 402. Additionally or alternatively, some of these accessory components could be secured within the housing 402.

The power receiver(s) 404 can be configured to receive power that is transferred by a source external from the accessory, such as the user device. As described above, the power can be transferred via a physical connection (e.g., by a physical coupling of electrical contacts) or a wireless connection (e.g., by a power transmitter chip). The wireless transceiver(s) 406 are operable to transmit data signals to wireless transceiver(s) of the user device. The magnet(s) 408, meanwhile, enable the camera accessory 400 to be securely attached to a wireless accessory bus of a user device. Oftentimes, the user device will include magnet(s) that are positioned in a similar arrangement so that as the camera accessory 400 and user device are drawn toward one another when located within a close proximity.

Note that the camera accessory 400 is simply one example of an accessory that could be attached to a user device. Other accessories could include a depth sensor/camera, an external storage device, an auxiliary power supply, an infrared sensor/camera, a laser rangefinder, a structured-light three-dimensional (3D) scanner, a memory card reader, an audio output device (e.g., speaker, headphones), or a supplemental display (e.g., an electronic ink display or LCD display). One skilled in the art will recognize that many other accessories offering different functionalities could also utilize the technology described herein.

FIG. 5 is a high-level block diagram illustrating exemplary components of a user device 500 and an accessory 550. Various embodiments of the user device 500 and the accessory 550 can include some or all of these components, as well as additional components not illustrated here.

The user device 500 can include one or more processors 504, a wireless transceiver 506, a power transmitter 508, a power receiver 510, a display 512, a memory 514, and/or a power supply 516 electrically coupled to a power interface 518. These components can be retained within a housing 502 that includes one or more magnets 520 arranged to securely receive the accessory 550. The wireless transceiver 506 can be configured to automatically establish a wireless connection with the wireless transceiver 556 of the accessory 550. The wireless transceivers 506, 556 allow data to be transmitted between the accessory 550 and the user device 500. More specifically, the wireless transceiver(s) 506, 556 may communicate with one another using a bi-directional communication protocol, such as Near Field Communication (NFC), wireless Universal Serial Bus (USB), Bluetooth, WiFi, a cellular data protocol (e.g., 3G or 4G), or a proprietary point-to-point protocol.

In some embodiments, the accessory 550 does not include a dedicated power source, and thus must receive power from the user device 500. The power transmitter 508 may be configured to transfer power from the power supply 516 of the user device 500 to the accessory 550. For example, the power transmitter 508 of the user device and the power receiver 558 of the accessory 550 may be electrically coupled to one another via a physical connection (e.g., by electrical contacts) or a wireless connection (e.g., by power transmitter chips).

The accessory 550 could also include an auxiliary power supply 560 and a power transmitter 562 that allow the accessory to serve as a supplemental power source for the user device 500. In such embodiments, the user device includes a power receiver 510 that is able to receive power (e.g., wirelessly or via electrical contacts) from the accessory 550. Oftentimes, the user device 500 will include a display 510, a memory 514, and a power supply 516 that is electrically coupled to a power interface 518 (e.g., a physical power port or a Qi-compliant wireless receiver). The memory 514 can include, for example, an operating system executed by the user device 500 and one or more applications that are associated with various accessories. The user device 500 may be configured to invoke a particular application upon determining the corresponding accessory has been attached to the wireless accessory bus. The power supply 516, meanwhile, may include a rechargeable lithium-ion (Li-Ion) battery, a rechargeable nickel-metal hydride (NiMH) battery, a rechargeable nickel-cadmium (NiCad) battery, or any other power source suitable for electronic user devices.

In some embodiments, the wireless accessory bus is designed so that multiple accessories can simultaneously be attached to, and used by, the user device 500. For example, a user may elect to concurrently utilize camera accessory 302a and external storage accessory 302b of FIG. 3. In such embodiments, the magnet(s) 520 and/or wireless transceiver 506 may be arranged so that multiple accessories can be utilized without damaging throughput or performance.

The accessory 550 can include one or more processors 554, a wireless transceiver 556, a power receiver 558, an auxiliary power supply 560, a power transmitter 562, a memory 564, one or more digital cameras 566, an image processing module 568, and/or a display 570. These components can be retained within a housing 552 that includes one or more magnets 572 arranged so as to enable the accessory 550 to be securely attached to the electronic device 500.

As noted above, various embodiments of the accessory 550 can include some or all of these components, as well as other additional components not illustrated here. For example, an accessory intended to serve as a supplemental display to the user device 500 may include processor(s) 554, a wireless transceiver 556, a power receiver 558, a memory 564, and a display 570. As another example, an accessory designed to capture images may include processor(s) 554, a wireless transceiver 556, a power receiver 558, a memory 564, digital camera(s) 566, and an image processing module 568.

Note that in some embodiments the accessory 550 (or some subset of its components) could be integrated into a case, cover, or clip designed for the user device. That is, cases, covers, clips, etc., may be designed to make use of the wireless accessory bus when affixed to the user device 500. For example, an auxiliary power supply 560 or additional memory 564 could be integrated into a case for a mobile phone. The auxiliary power supply 560 and/or additional memory 564 may be usable by the mobile phone so long as the mobile phone remains within the case.

FIG. 6 depicts a process 600 for manufacturing a user device that includes a wireless accessory bus to which accessories can be detachably connected. A housing is initially received (e.g., by a manufacturer) that is designed to protect various components (e.g., sensors, connectors, power supply) that reside within the user device (step 601). In some embodiments, a break is created in the housing (step 602). The break may be necessary for permitting antenna(s) within the housing to send and receive signals or could be for stylistic/aesthetic purposes.

Fastening components can then be affixed to the housing. For example, in some embodiments one or more magnets are secured to the inner surface of the housing near the break (step 603). The magnet(s) permit accessories to be securely attached to the housing without requiring mechanical clips or connectors. Additionally or alternatively, a magnetic film could be deposited along the outer or inner surface of the housing. The user device can also be designed so that a power transmitter and/or a wireless transceiver are disposed in or near the break (step 604). As shown in FIG. 2, the fastening component(s) (e.g., magnets), power transmitter, and/or wireless transceiver collectively form a wireless accessory bus to which accessories can be magnetically, electrically, and/or communicatively coupled.

The user device, which includes a wireless accessory bus, can then be assembled and provided to a user (step 605). The wireless accessory bus permits the user to readily and repeatedly attach and detach the user device from accessories (step 606). For example, as the user brings an accessory and the user device within a close proximity to one another, the magnet(s) secured to the inner surface of the housing may magnetically draw the accessory toward the wireless accessory bus. When the accessory is attached to the user device, the user device may automatically allow the user to utilize a new or improved functionality enabled by the accessory (step 607). For example, the user device may be able to capture an image using a camera accessory or project audio using a speaker accessory without requiring modification/installation of any hardware or software.

FIG. 7 depicts a process 700 for allowing a user device to utilize a new or improved functionality enabled by an accessory. A user initially acquires a user device that includes a wireless accessory bus (step 701). The user device could be, for example, user device 200 of FIG. 2 or any other suitable electronic device. The wireless accessory bus enables the user to attach an accessory to the user device (step 702). The accessory and the user device could be magnetically adhered or physically coupled (e.g., via clips, connectors, or a mechanical track) to one another.

Typically, the user device continually monitors whether an accessory has been attached to the wireless accessory bus (step 703). For example, a processor within the user device may be configured to detect when an accessory is placed on or near the wireless accessory bus. More specifically, a wireless transceiver within the user device may be able to detect when another wireless transceiver comes within a certain proximity, thereby indicating the presence of an accessory. When an accessory is attached to the wireless accessory bus, the user device can electrically couple the power supply of the user device to a power receiver of the accessory (step 704). For example, the power supply of the user device may be coupled to a power transmitter that is configured to wirelessly transfer power to the power receiver of the accessory.

The user device may also be configured to communicatively couple a wireless transceiver of the user device to a wireless transceiver of the accessory (step 705). The wireless transceivers can permit the user device and the accessory to communicate with one another without a physical connection between the two components. After initiating a communication channel between the user device and the accessory, the user device can allow the user device to utilize a new or improved functionality enabled by the accessory (step 706). In some embodiments, this is done automatically without requiring further user input. That is, the user may be able to utilize the accessory without manually connecting/modifying physical components or installing appropriate software. For example, the user device may automatically recognize and utilize additional memory provided by an external storage accessory.

Unless contrary to physical possibility, it is envisioned that the steps described above may be performed in various sequences and combinations. For instance, the user device may not need to form an electrical coupling with the accessory if the accessory includes its own power. Other steps could also be included in some embodiments. For example, the user device may automatically initiate an application associated with the accessory attached to the wireless accessory bus. More specifically, when a camera accessory (e.g., camera accessory 400 of FIG. 4) is attached the user device, the user device (and, more specifically, an operating system executed by the user device) may invoke and execute a camera application and/or an image processing application.

Processing System

FIG. 8 is a block diagram illustrating an example of a processing system 800 in which at least some operations described herein can be implemented. The computing system may include one or more central processing units (“processors”) 802, main memory 806, non-volatile memory 810, network adapter 812 (e.g., network interfaces), video display 818, input/output devices 820, control device 822 (e.g., keyboard and pointing devices), drive unit 824 including a storage medium 826, and signal generation device 830 that are communicatively connected to a bus 816. The bus 816 is illustrated as an abstraction that represents any one or more separate physical buses, point to point connections, or both connected by appropriate bridges, adapters, or controllers. The bus 816, therefore, can include, for example, a system bus, a Peripheral Component Interconnect (PCI) bus or PCI-Express bus, a HyperTransport or industry standard architecture (ISA) bus, a small computer system interface (SCSI) bus, a universal serial bus (USB), IIC (I2C) bus, or an Institute of Electrical and Electronics Engineers (IEEE) standard 1394 bus, also called “Firewire.”

In various embodiments, the processing system 800 operates as part of a user device (e.g., user device 200 of FIG. 2), although the processing system 800 may be connected (e.g., wired or wirelessly) to the user device. In a networked deployment, the processing system 800 may operate in the capacity of a server or a client machine in a client-server network environment, or as a peer machine in a peer-to-peer (or distributed) network environment.
