RECEIVER DEVICES CONFIGURED TO DETERMINE LOCATION WITHIN A TRANSMISSION FIELD

摘要

Embodiments disclosed herein may generate and transmit power waves that, as result of their physical waveform characteristics (e.g., frequency, amplitude, phase, gain, direction), converge at a predetermined location in a transmission field to generate a pocket of energy. Receivers associated with an electronic device being powered by the wireless charging system, may extract energy from these pockets of energy and then convert that energy into usable electric power for the electronic device associated with a receiver. The pockets of energy may manifest as a three-dimensional field (e.g., transmission field) where energy may be harvested by a receiver positioned within or nearby the pocket of energy.

主权项

1. A computer-implemented method comprising:
receiving, by a receiver device, from a transmitter device, an exploratory power wave and a communications signal requesting a feedback communications signal based upon the exploratory power wave; transmitting, by the receiver, the feedback communications signal containing data indicating a location of the receiver relative to the transmitter within a transmission field; receiving, by the receiver, a second exploratory power wave and a second communications signal requesting a second feedback communications signal based upon the second exploratory power wave; and transmitting, by the receiver, the second feedback communications signal containing data indicating a comparatively more granular location of the receiver relative to the transmitter within the transmission field.
