The present invention relates to wireless power supply systems.
Point of sale systems can generally include a series of shelving units that can hold products and associated signage. Point of sale systems have benefited from recent improvements in product packaging. Contemporary product packaging increasingly utilizes RFID labels as one aspect of inventory control, anti-counterfeiting and/or tamper-proofing measures. Product packaging can also serve more traditional functions, including providing a secure housing for a product while also displaying product specifications, compatibility information, power requirements, and hardware requirements.
Some known product packaging includes a secondary tank circuit for receiving wireless power. The secondary tank circuit is electrically coupled to one or more visual elements, speaker elements or both. The visual elements can include one or more LEDs, OLEDs, LCD displays and e-ink displays, and the speaker element can include an electrostatic speaker, for example. The secondary tank circuit can be formed on a printed label adhered to the product container.
Products utilizing wirelessly powered e-ink visual elements have been applied to cereal boxes. The display surface for a cereal box can each include only a portion of the original graphic, such that the entire graphic is proportioned to fit just entirely over the display surface on five boxes of cereal. In addition to resizing, the graphics can animate or illuminate, including the entire graphic or only portions thereof. Further, the e-ink graphics can be used to automatically reconfigure product packaging or signage to correspond to a sale or a season. Wirelessly powered product packaging can generate a visual output to promote or otherwise draw attention to a package or packages at the point of sale.
The present invention provides a wireless power supply system in which a remote device is provided with different control methodologies depending on the situation. A wireless power supply system generally includes one or more wireless power supplies that supply energy inductively to one or more remote devices. The different control methodologies enable the wireless power supply system to operate the remote device in different modes depending on the nature of the wireless power supply. In some embodiments, the different modes can be enabled without additional circuitry on the remote device and without user interaction. One type of wireless power supply can selectively control the one or more remote devices according to a first control methodology and another type of wireless power supply can control the remote device according to a second control methodology.
In some embodiments, the wireless power supply system includes a point of display or commercial control methodology and a point of use or residential control methodology. The point of display control methodology provides a demonstration mode that controls a load of the remote device to demonstrate a feature of the remote device. For example, in demonstration mode, one or more lights on the remote device may be illuminated in a sequence or pattern to attract attention to the device. The point of use control methodology provides a use mode that controls a load of the remote device. The point of use control methodology can be implemented in a point of use wireless power supply that controls the remote device while the remote device is being charged or powered by the point of use wireless power supply. For example, in use mode, the one or more lights may be illuminated by the point of use wireless power supply to indicate the device is being charged rather than to attract attention to the device. Alternatively, the point of use control methodology can be implemented in the remote device itself to control a load of the device while the remote device is in use. For example, in use mode, a battery of the remote device may be used to power the one or more lights to indicate the amount of charge left in the battery. As another example, where the remote device is a wirelessly powered article of footwear, the one or more lights in use mode may be illuminated depending on output from a pressure sensor in the article of footwear so that the article of footwear lights up in response to a user walking, running, or jumping.
In some embodiments, a wireless power supply is programmed to operate a remote device according to a primary control methodology and the remote device is programmed to operate the remote device according to a secondary control methodology. In these embodiments, the remote device includes circuitry for enabling the primary control methodology instead of the secondary control methodology. For example, the remote device may include a bypass switch that selectively provides a current path from the wireless power receiver to a load of the remote device, which enables the wireless power supply to control that load directly. In some embodiments with a bypass switch, the bypass switch is manually accessible by a user. In other embodiments, the wireless power supply may communicate with the remote device to activate the bypass switch. In yet other embodiments, the remote device may include a sensor that senses a characteristic of power from the wireless power supply and activates the bypass switch in response. Not all embodiments include a bypass switch. In some embodiments, the remote device may include a controller capable of carrying out instructions from the wireless power supply to implement the primary control methodology indirectly.
These and other objects, advantages, and features of the invention will be more fully understood and appreciated by reference to the description of the current embodiment and the drawings.

Nor should the use of enumeration be construed as excluding from the scope of the invention any additional steps or components that might be combined with or into the enumerated steps or components.
The present invention provides that different control methodologies are implemented in a wireless power supply system depending on one or more factors. The wireless power supply system can selectively control the one or more remote devices according to a first control methodology when in a first mode and according to a second control methodology when in a second mode. In one embodiment, a wireless power supply system is provided for wirelessly powering a display circuit in a product while located at a point of display differently than when charging at a point of use, or when the device is in use. In another embodiment, a wireless power supply is programmed to operate a remote device according to a primary control methodology and the remote device is programmed to operate the remote device according to a secondary control methodology where the remote device includes circuitry for enabling the primary control methodology instead of the secondary control methodology.

The present invention is suitable for use with a wide variety of wireless power supplies. Wireless power supplies may provide wireless power through the electromagnetic near field power, the electromagnetic far field, magnetic resonance, or any other suitable wireless power source. For example, the wireless power supply may be a resonant inductive power supply such as the wireless power supply shown in
In the illustrated embodiment, the wireless power supply 102 includes a primary controller 120, mains rectification circuitry 122, a DC/DC converter 124, an inverter 126, and a tank circuit including a primary 130 and a capacitor 128. In operation, the mains rectification 122, primary controller 120, DC/DC converter 124, and inverter 126 apply power to the tank circuit 320 to generate a source of electromagnetic inductive power.
In the illustrated embodiment, the wireless power supply 102 is configured to wirelessly supply power using generally conventional inductive power transfer techniques and apparatus. The specifics regarding most resonant and non resonant inductive wireless power transfer techniques are known, and thus will not be discussed in great detail. In general, the primary 130 may produce an electromagnetic field that may be picked up and used to generate power in a wireless electronic device, sometimes referred to as a remote device. The primary 130 of this embodiment is a primary coil of wire configured to produce an electromagnetic field suitable for inductively transmitting power to a remote device 104.
The wireless power supply 102 includes an AC/DC rectifier 122 for converting the AC power received from the AC mains into DC power. The power supply 102 also includes a DC/DC converter 124 for converting the DC output of the AC/DC rectifier 122 to the desired level. The power supply 102 also includes a microcontroller 120 and an inverter 126 (sometimes referred to as a switching circuit). The microcontroller 120 is programmed to control the inverter 126 to generate the appropriate AC power for the primary 130. In this embodiment, the microcontroller 120 can control operation of the DC/DC converter 124 or the inverter 126. The microcontroller 120 may determine the appropriate DC power level or the appropriate operating frequency based on signals received from the wireless device. These signals may be communicated from the wireless device to the power supply 102 by reflected impedance or through a separate communications system, such as a separate inductive coupling utilizing for example, near field communication protocol, infrared communications, WiFi communications, Bluetooth communications or other communication schemes. The microcontroller 120 may follow essentially any of a wide variety of inductive power supply control algorithms. In some embodiments, the microcontroller 120 may vary one or more characteristics of the power applied to the primary 130 based on feedback from the remote device 104. For example, the microcontroller 102 may adjust the resonant frequency of the tank circuit (e.g. the coil and capacitor combination), the operating frequency of the inverter 126, the rail voltage applied to the primary or switching circuit to control amplitude 130 or the duty cycle of the power applied to primary 130 to affect the efficiency or amount of power inductively transferred to the remote device 104. A wide variety of techniques and apparatus are known for controlling operation of an inductive power supply. For example, the microcontroller may be programmed to operate in accordance with one of the control algorithms disclosed in the references incorporated by reference above.
Another type of wireless power supply is a near field far edge wireless power supply. The specifics regarding near field far edge wireless power supplies are known, and thus will not be discussed in detail. This system uses a larger primary inductive loop with a higher Q to induce a higher magnetic profile for additional distance while reducing the required energy within the resonant system.
In order to simplify discussion with regard to
The specifics regarding wireless power receivers are known and therefore will not be discussed in detail. Several different types of inductive power receivers are described in the disclosures incorporated by reference above. A closely coupled power receiver that can receive wireless power over a range of frequencies may include an inductor that acts as a wireless power receiver. may include an inductor A resonant induction power receiver may include an isolated LC circuit and a secondary coil for coupling to the LC circuit. This system is designed to have a higher Q and extend the magnetic field to provide a medium range power source.
In the
The wireless power supply controller 3d and remote device controller 3h can each be programmed with a wide variety of different algorithms. For example, the wireless power supply controller 3d can include algorithms for detecting presence of the remote device, communicating with the remote device, and supplying power to the remote device. Examples of algorithms for the remote device controller 3h may include a battery charging algorithm and an algorithm for communicating with the wireless power supply.
In the
In some embodiments, such as the
In some embodiments, the remote device 3c detects the type of wireless power supply 3b. The type of wireless power supply can be determined in a variety of different ways.
In one embodiment, the remote device is programmed to determine the type of wireless power supply based on a sensed characteristic of power in the remote device. Certain types of wireless power supplies can be programmed to transfer wireless power at a certain frequency or amplitude. For example, referring to
In another embodiment, a wireless power transmitter can be configured to sweep the operating frequency being transmitted over time to cause a glowing effect on the display element. As the frequency sweep passes near the resonant frequency of the resonator L3, the display element controller 5h can determine that the wireless power supply is not configured as a charging location. Accordingly, the display element controller can create a glowing effect using the control switch 5i, or activate the bypass switch 5j and allow the frequency sweep to intensify and dim the display element 5k over time as the frequency changes and therefore the amount of power transfer changes. A remote device may also determine the type of wireless power being provided by identifying a different characteristic of the power signal other than frequency such as voltage, current, phase, or any other type of power characteristic.
For embodiments that determine the type of wireless power supply using a sensed characteristic, that information can be used to determine its location. For example, certain types of wireless power supplies or certain values or thresholds of characteristics of sensed power can be associated with certain kinds of locations. The remote device can configure its operation based on that location information. For example at a point of use or charging location the display may be programmed to not turn on. Alternatively, the remote device may turn on a portion of the display to identify to a user that it is in a charging state. Additionally, if a remote device detects that a wireless power supply has over a threshold amplitude, a varying operating frequency or both, it may determine that it is located at a point of display, such as a store shelf and turn on its display capabilities and either not charge its internal energy storage element, or only use a portion of the received energy to charge its internal storage element.
In another embodiment, the wireless power supply may communicate an ID or other information that tells the remote device the wireless power supply type. For example, the wireless power supply can identify itself as a charger, display shelf, information booth, or any other type of wireless power or information transceiver. Different types of wireless power supplies may have different IDs. The ID can be used to look up the location of the wireless power supply. Alternatively, the ID or a portion of the ID may be indicative of the location of the wireless power supply. Alternatively, the wireless power supply may communicate its location to the remote device and the location can indicate the type of wireless power supply. That is, the wireless power supply can be programmed to control the remote device differently depending on the location of the wireless power supply. For example, the wireless power supply can tell the remote device that it is a wireless power supply located at a point of display, such as a storefront or tradeshow, or that it is a wireless power supply located at a point of use, such as a residence or other charging location. In some embodiments, if the wireless power supply identifies itself as a charging location through a communication transceiver, the remote device may determine not to turn on its display. In other embodiments, the remote device may turn on and control its own display based on communication from the wireless power supply, or it may configure a bypass switch to allow the wireless power supply to control the display on the remote device such as the configuration shown in
In some embodiments, the location of the wireless power supply may be set at manufacture or changed during operation. In other embodiments, the location can be manually set appropriately by a user at the point of display or the point of use, for example by using a demo mode switch. Alternatively, a GPS or other location system can determine the location of the wireless power supply and update the location setting automatically.
Different types of wireless power supplies can be programmed with different control algorithms. A wireless power supply located at a point of display, such as a storefront, may control a remote device differently than a wireless power supply located at a point of use, such as a residence. For example, a point of display wireless power supply may supply power to a remote device in order to charge the battery of the remote device and activate a load, such as a lighting or audio circuit, to attract attention to the remote device at the point of display. A point of use wireless power supply may supply power to a remote device in order to charge the battery of the remote device and activate the load for a different purpose, such as to simply indicate that the device is being charged. In some embodiments, the point of use wireless power supply may just charge the battery not activate the remote device load at all.
In one embodiment, the wireless power supply controller 3d can communicate with the remote device controller 3h. For example, the wireless power supply controller 3d and remote device controller 3h can modulate and demodulate communication signals transmitted using the wireless power transmitter and wireless power receiver. The communication signals can be transmitted using backscatter modulation. In another example, the wireless power supply controller 3d and remote device controller 3h can include RF transceivers for communication. Essentially any protocol or communication scheme can be implemented such as Bluetooth, WiFi, NFC, Zigbee, or any other communication protocol. This embodiment may be implemented using essentially any systems and methods capable of receiving communication over the inductive power link. Suitable communications receivers (including various detector circuits) and various alternative communications methods are described in U.S. application Ser. No. 13/012,000, which is entitled SYSTEMS AND METHODS FOR DETECTING DATA COMMUNICATION OVER A WIRELESS POWER LINK, and was filed on Jan. 24, 2011, by Matthew J. Norconk et al, and U.S. application Ser. No. 13/366,605, which is entitled SYSTEM AND METHOD OF PROVIDING COMMUNICATIONS IN A WIRELESS POWER TRANSFER SYSTEM, and was filed on Feb. 6, 2012, by Matthew J. Norconk et al, both of which are incorporated herein by reference in their entirety.
In some embodiments, there is no communication between the wireless power supply controller 3d and the remote device controller 3h. In these embodiments, the mode of the remote device can be changed either by a user activating a manual bypass switch or by sensing a characteristic of power in the wireless power receiver and activating the bypass switch in response. Where a manual bypass switch is implemented, the control line from the remote device controller 3h for the bypass switch is optional.

If the remote device 6c is not in proximity to the wireless power supply 6b, the controller 6i may determine to provide power to the resonator 6f, which can be used to power the display circuit 6g. The wireless power receiver 6h can be utilized as a wireless power transmitter by activating it and driving it with an AC waveform. The removable monitor may be separable from the device and may be placed in other garments or devices and can be used to activate lighting, display, or communication with other devices as well, as shown in
The removable monitor can include memory that stores data regarding the device or user. For example, information relating to sensor readings, gait analysis, user settings or preferences can be stored in memory on the removable monitor such that when a new device (such as a shoe for example) is purchased, the removable monitor is transferrable to the new device and all of the user data comes with it. The data can also be used in a point of display application to identify to a kiosk in a store what type of activity the user is involved in, this information can be used for product recommendations both in new items and supporting items.
In some embodiments, the display module may be configured to have two resonant points such as in the circuit shown in
In the illustrated embodiment of
The wireless power system 11A may also include a container 11D, such as a package or bag with or without logo lighting, internal lighting, or a combination thereof. The container 11D may be capable of holding one or more remote devices 11C, including for instance shoes and additional remote devices 11C as shown in the illustrated embodiment. The wireless power supply system 11A may be used without a container 11D such that remote devices 11C may be individually positioned in proximity to the wireless power supply 11B, as shown in the illustrated embodiment. In one embodiment, the container 11D may include wireless receiver circuitry (not shown) and lighting (not shown) capable of operating in a manner similar to the remote devices 11C so that the lighting may be activated in one or more modes, either actively or passively by the wireless power supply 11B.
In one embodiment, the container 11D may include a resonator 11E, such as a resonating coil, potentially capable of extending the range over which the remote devices 11C within the container 11D may receive power inductively. The resonator 11E may be integral to the container 11D construction or may be removable and replaceable. For example, the resonator 11E may be in the form of a pad capable of being placed near the bottom of the container 11D and upon which the remote devices 11C may rest within the container 11D. Although described in connection with resonator 11E, other resonator constructions may be used, including for example those described in U.S. Ser. No. 61/584,281 to Baarman et al., filed on Jan. 8, 2012, entitled INDUCTIVE COOKING SYSTEM and U.S. Patent Application Publication 2011/00304216 to Baarman, filed on Jun. 9, 2011, entitled COIL CONFIGURATIONS FOR INDUCTIVE POWER TRANSFER—all of which are incorporated herein by reference.
As mentioned above, the resonator 11E may potentially extend the range over which remote devices 11C may receive power. In one embodiment, the container 11D may include additional circuitry (not shown) adapted to monitor power in the resonator 11E and adapted to provide user feedback indicative of status information about the remote devices 11C. The level of power in the resonator 11E may indicate characteristics of the remote devices 11C, such as whether the remote devices 11C are actively receiving power, whether any remote devices 11C are present, and whether the remote devices 11C are being charged or are fully charged. Based on the level of power, the additional circuitry of the container 11D may provide feedback indicative of one or more of these characteristics. For example, when remote devices 11C are present and charging, the additional circuitry may cause the lighting to be a certain color or to blink. And, when the remote devices 11C are fully charged, the lighting may change to a different color or may remain steadily on.
In an alternative embodiment, a resonator 11E may be incorporated into a first remote device 11C in order to both power that remote device 11C and power a separate, second remote device 11C located above, next to, in, or near the remote device 11C. In one embodiment, both the first and second remote devices 11C may be inside a container 11D. Or the first remote device 11C may be within or comprise the container 11D so that the second remote device 11C may receive power therefrom while in the container 11D or when placed in proximity to the container 11D. In another alternative embodiment, the container 11D may include a resonator 11E separate from the first remote device 11C positioned within the container 11C.
By using a resonator 11E in a container 11D while the container 11D is placed on or in proximity to a wireless power supply 11B, one remote device 11C in the container 11D may be powered for charge or data capture, another remote device 11B on top of the container 11D may be energized for displaying information or lighting effects. Or multiple similar containers 11D containing resonators 11E may be placed on top of each other and receive power as well, thus forming a tower of containers 11D that are activated from one power supply through the resonators 11E.
In one configuration of the illustrated embodiment of
The bag 11D may include circuitry (not shown) capable of obtaining status information, such as charge status, about each remote device 11C by monitoring the amount of power (e.g., the size of the field) in the resonator 11E. For example, the circuitry of the bag 11D may compare the amount of power in the resonator 11E to a known amount of power associated with a known status. When the power level reaches a threshold level indicative of fully charged remote devices 11C, the bag 11D may indicate through its display that the remote devices 11C are charged. Although described with in connection with a sports bag 11D, it should be understood that this embodiment may be used in conjunction with any of type of container 11D or a remote device 11C that comprises a container 11D.
In a embodiment similar to the power sharing embodiment of containers 11D described above, remote devices 11C may each contain resonators 11E that enable power sharing from a wireless power supply 11B to a first remote device 11C and then to one or more additional remote devices 11C. For example, in embodiments in which garments are remote devices 11C, wireless power may be transferred from one garment to the next. Other remote devices 11C, such as shoes, may also receive power from garments comprising remote devices 11C. For example, a shoe may receive power from a pantleg through a pair of resonators 11E, one of which is disposed near the bottom of the pantleg in the hem and the other of which is disposed around the opening of the shoe. With this configuration, the two resonators 11E may achieve relatively good coupling and power transfer. Because the shoe in this example is a remote device 11C, it may include circuitry as described herein, such as power sensors or display elements, and may be used to power other remote devices 11C or feedback items in the pants. Although described in connection with a single pair of pants and shoes, it should be understood that other garments or remote devices 11C may be powered in a similar manner and that garments worn by one person may receive power from garments worn by another person.
The illustrated embodiment of
In the illustrated embodiment, information transmitted to the wireless power supply 12B by the remote devices 12C may prompt the wireless power supply 12B to change the information on the electronic display 12D. The transmitted information may be an identity of the remote device 12C, which the wireless power supply 12B can use to look up whether to change the information on the electronic display 12D. For example, the wireless power supply 12B may contain a look up table of information to determine which information to display on the electronic display 12D, or it may communicate with an external server containing a database of information to determine which information to display. In an alternative embodiment, the remote device 12C may not transmit information to the wireless power supply 12B; rather, the wireless power supply 12B may determine a characteristic about the remote device 12C, such as identity or class, in order to determine what information to display on the electronic display 12D. An example system in which the wireless power supply 12B may determine such characteristics is described in U.S. Pat. No. 7,989,986 to Baarman et al., issued Aug. 2, 2011, entitled INDUCTIVE POWER SUPPLY WITH DEVICE IDENTIFICATION—the disclosure of which is incorporated herein by reference in its entirety.
Turning to the illustrated embodiment of
In the illustrated embodiment, the wireless power supply system 13A may be a point of sale display capable of controlling an array of remote devices 13C, which are shoes in this embodiment but may be another type of remote device 13C. The wireless power supply system 13A may control a lighting effect of each remote device 13C according to any one of the methodologies described herein. A central controller (not shown) may coordinate the lighting effects within the wireless power system 13A so that patterns or sequences of lighting effects can be produced. For example, the central controller may prompt each wireless power supply 13B to turn on or off a lighting effect of the remote device 13C in proximity to the wireless power supply 13B. In this way, a pattern or sequence of lighting effects may be produced. The pattern or sequence, for instance, may be a complex graphic, moving effect, or another visual effect. For example, each associated wireless power supply 13B and remote device 13C in the illustrated embodiment is assigned a location identifier (e.g., a number). The central controller may use this location identifier to execute preprogrammed patterns or sequences, such as step one—1, 2, 3; step two—4, 2, 6; step three—7, 5, 3; and step four—1, 5, 9. Other sequence combinations may be implemented in order to produce a different effect. As an example, the sequence may produce a flashing wave effect to simulate shoes running along the point of sale display.
In the illustrated embodiment, the wireless power supply system 13A may use an active shelving or retail display case such that a subset of wireless power supplies 13B may identify remote devices 13C placed on charging surfaces associated with each wireless power supply 13B. The wireless power supplies 13B may communicate with the central controller to update information about the remote device 13C as well as to control the display pattern of the retail display. Each wireless power location (or subset of locations) may have a microcontroller configured to identify when a remote device 13C is present on the wireless charging location, and in response to an indication of presence, obtain identifying information about the remote device 13C. The wireless power supply 13B may use a communication channel to obtain information from the remote device 13C, or alternatively, the wireless power supply 13B may identify key features of the remote device 13C by varying the applied power signal. For example, the wireless power supply 13B may sweep its transmit frequency to identify one or more resonant points of the remote device 13C indicative of the identity or class of the remote device 13C present in proximity to the wireless power supply 13B.
Once the wireless power supply 13B has identified the remote device 13C, it may pass the identity information to the central display controller. The central display controller may be able to access information about the remote device by use of a lookup table or database. This table or database may be stored within the central display controller, or it could be stored in a remote server and accessed through a data connection such as an internet or LAN connection. Once information about the remote device 13C is identified, the central display controller may communicate to the wireless power supply 13B to display certain information about the remote device 13C on the electronic display 13D. This display information could include price and promotion information, shoe/garment size, available inventory, suggested uses, or other related information. Alternatively, each wireless power supply 13B may have its own look-up table or database that it uses to update the display information on the electronic display 13D.
For purposes of disclosure, the method of sequencing and patterns are described in connection with the wireless power supply system 13A, but other systems may be implemented in the present invention, including those described in U.S. Patent Application Publication 2011/00259960 to Baarman et al., filed Apr. 8, 2011, published Oct. 27, 2011, entitled POINT OF SALE INDUCTIVE SYSTEMS AND METHODS—the disclosure of which is incorporated herein by reference in its entirety.
In the illustrated embodiment of
At each location in the point of sale display of the wireless power supply system 14A, the remote devices 14C, wireless power supplies 14B, or both may communicate with the central controller 14E to provide information about the type of remote device 14C present. The type of remote device present may be determined in a manner similar to that described with respect to
The central display controller 14E may also have the ability to collect user instructions about the desired display mode. For example, an input interface 14F, such as a keyboard, touchscreen, mouse, or other type of user input device, may be used to communicate with the central display controller 14E. Based on user input from the input interface 14F, the central display controller 14E may communicate to the individual wireless power supplies 14B to control the power being supplied to the remote devices 14C. For example, if a user requests a demo mode, the central display controller 14E may turn on the individual wireless power supplies 14B in a sequential order, illuminating the display or lighting effects on the remote devices 14E. This sequential order may be in a horizontal, vertical, or any other pattern and may also include an every-other order on two adjacent rows, giving the illusion of a ‘running’ pattern, such as one of the patterns described in the illustrated embodiment of
In the illustrated embodiment, the central controller 14E is coupled to the input interface 14F. By using the input interface 14F, a user may configure the point of sale display into a demonstration mode, or highlight specific remote devices 14C (e.g., products) that fall within a certain category. For example, the user might prompt the central controller 14E to highlight all sale items located in the point of sale display or all items less than a desired price point. As another example, the user might prompt the central controller 14E to highlight items available in stock having certain configurations, including for example highlighting those shoes available in stock in the user's shoe size. The central controller 14E may retrieve sale, price, or stock information from memory in order to control which remote devices 14C to highlight in the point of sale display. Alternatively, the central controller 14E may interface with an external memory or database to retrieve information, such as sale, price, or stock information, in order to control which remote devices 14C to highlight in response to user input.
Referring now to
Once a remote device 14C has been detected, the wireless power supply 14B may determine information about the remote device 14C, such as identity or class information, using any one of the methodologies described herein, including those described with respect to
In an alternative embodiment of the present invention, the communications capability of the wireless power system of the remote device may be used to implement functionality beyond feedback and control of the wireless power link. In this embodiment, the wireless power communication system can be used to transmit to and/or from the remote device communications that are not specific to wireless power transfer, such as communications that relate to the function of the remote device. Although implementations may vary, incoming communications may be relayed from the wireless power system to a separate control system within the remote device or they may allow a controller integrated into the wireless power system to directly control a feature or function of the remote device. Similarly, with regard to outgoing communications, the wireless power supply may wirelessly relay communications that are received from a separate controller within the remote device or it may be configured to generate communications based on input from separate components, such as sensors incorporated into the remote device.
As another example shown in
The wireless power communication system can also be used to transmit communications from the remote device to the wireless power supply or another external device. For instance, returning to the example of an article of footwear, statistics about a run can be sent to a treadmill as well so the treadmill can display a fuller picture of the runner's workout. Information related to a sport such as cadence, strike force, running form, pressure points, can all be sent from the article of footwear to the training device whether it is a treadmill, bicycle or other training equipment for sports. The article of footwear may include one or more sensors, such as a temperature sensor or pressure sensor capable of obtaining measurements that might be useful to an external device. Although the article of footwear may include essentially any type of sensor, in one embodiment, the article of footwear may include a piezoelectric sensor positioned within the sole of the shoe to provide a signal indicative of pressure and/or acceleration. It may also include a temperature sensor.
The communication link can also be used for developing awareness between similar devices. In a store, for example, a user may cross a threshold containing a primary where an identification is transferred. This communication may be used to support a “loyalty points” program where users can gain points for entering the store. The communication may be transmitted immediately or information concerning the trigger event may be stored and transmitted at later time when the shoe is proximate a wireless power supply or other system configured to collect stored information. If more information is stored in the shoe including miles ran, average run time, state of the shoe, the information could be used to understand the user and give more points based on criteria. Further, information collected or stored in a remote device may be used to change the remote device. For example, shoes with more than a predefined number of miles ran recorded on them can be configured change their active lighting color automatically, indicating reward level. As another example, information collected and stored in the shoe may be used to develop recommendations in the store as well. For example, information relating to exercise habits, such as distance run, speed, internal shoe temperature and pressure information may be useful in determining the appropriate shoes for a runner.
Other information stored in the shoe can include location or location history information via GPS or a list of communication links with fixed primary locations. Information about the user or about the shoe or item can be stored as well. This information may come from internal sensors contained within the shoe or it may come from external devices. With multiple garments enabled with a receiver, information can be stored regarding the combination of the items. Also garments can work together support a more successful experience whether it be for a sporting activity or for comfort.
