Patent ID: 11502551

Abstract:
A method of charging multiple receivers, the method includes: (i) receiving, via the communication radio, first data that allows the transmitter to determine a locations for a first receiver and a second receiver, (ii) determining waveform features used to transmit wireless power waves focused at the location of the first receiver, (iii) determining waveform features used to transmit wireless power waves focused at the location of the second receiver, (iv) causing a first subset of antennas to transmit wireless-power waves having the first waveform features to create focused energy at the location of the first receiver and (v) causing a second subset of antennas to transmit wireless-power waves having the second waveform features to create focused energy at the second location of the second receiver, where transmitting the wireless-power waves having the first waveform features occurs while transmitting the wireless-power waves having the second waveform features.
