WIRELESSLY CHARGE MULTIPLE WIRELESS-POWER RECEIVERS USING DIFFERENT SUBSETS OF AN ANTENNA ARRAY TO FOCUS ENERGY AT DIFFERENT LOCATIONS, AND SYSTEMS AND METHODS OF USE THEREOF ELECTROMAGNETIC WAVES TO

Abstract:

Wireless charging systems, and methods of use thereof, are disclosed herein. As an example, a method includes: (i) receiving, by a communications radio of a wireless power transmitter, a communication signal from a communications radio of a wireless power receiver, (ii) determining a signal strength of the communication signal, (iii) determining whether the receiver device is within a proximity threshold from the transmitter based, at least in part, on the signal strength of the communication signal, and (iv) determining at least one waveform characteristic for wireless power transmission waves based, at least in part, on the signal strength of the communication signal. The method further includes, in response to determining that the receiver device is within the proximity threshold: activating one or more antennas of the plurality of antennas to transmit the wireless power transmission waves to the receiver device.
