Abstract

In accordance with various aspects of the disclosure, a method and apparatus is disclosed that includes features of a receiving antenna configured to wirelessly receive power transmitted by a transmitting device and arranged to associate or dissociate with the transmitting device.

Claims

1. An apparatus comprising:

a power receiving unit (PRU) configured to wirelessly receive power transmitted by a power transmitting unit (PTU), the received power to be used by the PRU to provide operational power for the PRU and/or to charge a battery in the PRU,

wherein the PRU is also configured to wirelessly receive at least one command from the PTU through a Bluetooth link and to wirelessly transmit at least one parameter to the PTU through the Bluetooth link.

2. The apparatus of claim 1, further comprising a Bluetooth radio.

3. The apparatus of claim 1, wherein the at least one parameter comprises a charge status of the battery.

4. The apparatus of claim 1, wherein the PRU further comprises a switch to regulate the received power.

5. The apparatus of claim 4, wherein the at least one command is to be used to control the switch.

6. A method comprising:

wirelessly receiving power transmitted by a power transmitting unit (PTU);

using the received power to provide operational power and/or to charge a battery; and

wirelessly receiving at least one command from the PTU through a Bluetooth radio and wirelessly transmitting at least one parameter to the PTU through the Bluetooth radio.

7. The method of claim 6, wherein the at least one parameter comprises a charge status of the battery.

8. The method of claim 6, further comprising using a switch to regulate the reception of power.

9. The method of claim 8, further comprising using the at least one command to control the switch.

10. An apparatus comprising:

a power transmitting unit (PTU) configured to wirelessly transmit power to be received by a power receiving unit (PRU),

wherein the PTU is further configured to wirelessly transmit at least one command to the PRU through a Bluetooth link and to wirelessly receive at least one parameter from the PRU through the Bluetooth link.

11. The apparatus of claim 10, further comprising a Bluetooth radio.

12. The apparatus of claim 10, wherein the at least one parameter comprises a charge status of a battery in the PRU.

13. The apparatus of claim 10, wherein the at least one command is to be used to control a switch in the PRU for regulating reception of the power by the PRU.

14. A method comprising:

wirelessly transmitting power to be received by a wireless power receiving unit (PRU); and

using a Bluetooth radio to transmit at least one command to the PRU and to receive at least one parameter from the PRU.

15. The method of claim 14, wherein the at least one parameter comprises a charge status of a battery in the PRU.

16. The method of claim 14, wherein the at least one command is to be used to control a switch in the PRU for regulating the reception of power in the PRU.
