Wireless power and data transfer system with out of band communications hand off

1 . A method of operating a wearable electronic device that includes (i) a load, (ii) a wireless receiver system that comprises at least one receiver antenna operating at an operating frequency, and (iii) an out-of-band communications system, the method comprising:

receiving a wireless power and data transmission by the wireless receiver system, the wireless power and data transmission starting based on a wireless transmitter system determining presence of the wireless receiver system;

transmitting a power level at the load by the wireless receiver system to the wireless transmitter system;

receiving an out-of-band communications requests by the out-of-band communications system of wearable electronic device from an out-of-band communication system that is in operative communication with the wireless transmitter system, the out-of-band communications requests based on the wireless transmitter system determining the power level at the load exceeds a threshold for out-of-band communications;

transmitting a communications address associated with the out-of-band communications system of the wearable electronic device to the out-of-band communication system in operative communication with the wireless transmitter system;

connecting the out-of-band communication system of the wearable electronic device to the out-of-band communication system in operative communication with the wireless transmitter system; and

receiving out-of-band wireless data by the out-of-band communications system of the wearable electronic device based on the wireless transmitter handing over wireless data transmission to the out-of-band communication system in operative communication with the wireless transmitter system.

2 . The method of claim 1 , wherein the communications address is a media access control address (MAC address).

3 . The method of claim 1 , wherein the out-of-band communication system in operative communication with the wireless transmitter system and the out-of-band communications system of the wearable electronic device are both Bluetooth communications systems.

4 . The method of claim 1 , further comprising ending the receiving of the out-of-band wireless data by the out-of-band communications system of the wearable electronic device when a data transfer operation is complete.

5 . The method of claim 1 , wherein the operating frequency of the at least one receiver antenna is one of about 6.78 megahertz (MHz) or 13.56 MHz.

6 . The method of claim 1 , wherein the wireless receiver system further comprises a power conditioning system configured to (i) receive the wireless power and data transmission from the at least one receiver antenna, (ii) convert the received wireless power and data transmission to a DC power signal, and (iii) provide the DC power signal at least to the load.

7 . The method of claim 6 , wherein the wireless receiver system further includes a receiver controller, the method further comprising:

decoding the DC power signal, by the receiver controller, to extract a first data signal compliant with a wireless power and data transfer protocol;

decoding the first data signal compliant with the wireless power and data transfer protocol to extract a first asynchronous serial data signa;

encoding a second asynchronous serial data signal as a second data signal compliant with the wireless power and data transfer protocol; and

altering the DC power signal to encode the second data signal compliant with the wireless power and data transfer protocol into wireless power and data transmission; and

receiving out-of-band communications at the out-of-band communications system of the wearable electronic device in accordance with an out-of-band communications protocol.

8 . The method of claim 7 , wherein the second data signal continues transmission by the out-of-band communications system of the wearable electronic device when the out-of-band communications system in operative communication with the wireless transmitter system takes over wireless data transmission, and wherein the second data signal includes wireless power transfer related data.

9 . The method of claim 7 , wherein the out-of-band communications protocol s a Bluetooth protocol.
