Abstract

Exemplary embodiments are directed to wireless power. A wireless charging device may comprise a charging region configured for placement of one or more chargeable devices. The charging device may further include at least one transmit antenna configured for transmitting wireless power within the charging region. Furthermore, the charging device is configured to exchange data between at least one chargeable device of the one or more chargeable devices.

First claim

What is claimed is:

1. A chargeable device for wireless power reception, comprising:
a receiver circuit configured to wirelessly receive power from a wireless charging device via a wireless power transfer field at a level sufficient to charge or power the chargeable device; and
a processor electrically coupled to the receiver circuit and configured to detect the wireless power transfer field and activate a first profile of the chargeable device in response to detection of the wireless power transfer field, the first profile configured to set or generate at least one of a first audio volume level, a first vibration level, a first alert tone, a first lock setting, or any combination thereof.

2. The chargeable device of claim 1 , wherein the processor is further configured to detect the wireless power transfer field based on at least one of near-field communication or reflected impedance.

3. The chargeable device of claim 1 , further comprising a communication interface configured for wireless communication with a communication device, wherein the processor is further configured to transmit a first signal to the communication device via the communication interface, the first signal indicating that the communication device is within a communication range of the communication interface.

4. The chargeable device of claim 1 , further comprising a communication interface configured for wireless communication with a communication device, wherein the processor is further configured to detect the receiver circuit being removed from a charging region of the wireless charging device and transmit a second signal to the communication device via the communication interface in response to the receiver circuit being removed from the charging region.

5. The chargeable device of claim 1 , wherein the processor is further configured to detect the receiver circuit being removed from a charging region of the wireless charging device and activate a second profile in response to the receiver circuit being removed from the charging region, the second profile is configured to at least one of set a second audio volume level, set a second vibration level, and generate a second alert tone.

6. The chargeable device of claim 1 , further comprising a multi-media interface configured for programming at least one function of the wireless charging device, the at least one function including a time duration for wireless power transmission and a power level for wireless power transmission.

7. A method for wireless power reception, comprising:
wirelessly receiving, at a receiver circuit, power from a wireless charging device via a wireless power transfer field at a level sufficient to charge or power a chargeable device electrically coupled to the receiver circuit;
detecting the wireless power transfer field; and
activating, at the chargeable device, a first profile of the chargeable device in response to detection of the wireless power transfer field, the first profile configured to set or generate at least one of a first audio volume level, a first vibration level, a first alert tone, a first lock setting, or combination thereof.

8. The method of claim 7 , wherein detecting the wireless power transfer field comprises detecting the wireless power transfer field based on at least one of near-field communication or reflected impedance.

9. The method of claim 7 , further comprising transmitting a first signal to a communication device, the first signal indicating that the communication device is within a wireless communication range.

10. The method of claim 7 , further comprising:
detecting the chargeable device being removed from a charging region of the wireless charging device; and
transmitting a second signal to a communication device in response to the chargeable device being removed from the charging region.

11. The method of claim 7 , further comprising:
detecting the chargeable device being removed from a charging region of the wireless charging device; and
activating a second profile in response to the chargeable device being removed from the charging region, the second profile configured to at least one of set a second audio volume level, set a second vibration level, and generate a second alert tone.

12. The method of claim 7 , further comprising programming at least one function of the wireless charging device, the at least one function including a time duration for wireless power transmission and a power level for wireless power transmission.

13. A chargeable device for wireless power reception, comprising:
means for wirelessly receiving power from a wireless charging device via a wireless power transfer field at a level sufficient to charge or power a chargeable device;
means for detecting the wireless power transfer field; and
means for activating a first profile of the chargeable device in response to detection of the wireless power transfer field, the activating means electrically coupled to the receiving means, the first profile configured to set or generate at least one of a first audio volume level, a first vibration level, a first alert tone, a first lock setting, or any combination thereof.

14. The device of claim 13 , wherein the detecting means is configured to detect the wireless power transfer field based on at least one of near-field communication or reflected impedance.

15. The device of claim 13 , further comprising means for transmitting a first signal to a communication device, the first signal indicating that the communication device is within a wireless communication range.

16. The device of claim 13 , further comprising:
means for detecting the chargeable device being removed from a charging region of the wireless charging device;
means for transmitting a second signal to a communication device in response to the chargeable device being removed from the charging region; and
means for activating a second profile in response to the chargeable device being removed from the charging region, the second profile configured to at least one of set a second audio volume level, set a second vibration level, and generate a second alert tone.

17. The device of claim 13 , further comprising means for programming at least one function of the wireless charging device, the at least one function including a time duration for wireless power transmission and a power level for wireless power transmission.

18. The device of claim 13 , wherein the power receiving means comprises a receiver circuit, the detecting means comprises a first processor, and the first profile activating means comprises a second processor.

19. A communication device for communicating with a chargeable device, comprising:
an antenna circuit configured to receive a first signal from the chargeable device providing an indication that the antenna circuit is within a communication range of the chargeable device that is placed in a wireless power charging region of a wireless power charging device; and
a communication interface configured to determine whether the antenna circuit is within the communication range of the chargeable device and generate a first alert in response to determining that the antenna circuit is not within the communication range of the chargeable device,
wherein the antenna circuit is further configured to receive a second signal from the chargeable device providing an indication that the chargeable device has been removed from the wireless power charging region and wherein the communication interface is further configured to generate a second alert in response to
