Abstract: An example method disclosed herein includes: determining, by a transmitter, whether to transmit one or more power waves to a receiver location along a transmission path by comparing a receiver location and a path of the one or more power waves with a stored location of an entity to be excluded from receipt of power waves. The method also includes: measuring, by one or more sensors of the transmitter, power levels in a transmission field of the transmitter, the transmission field including the receiver location and the entity; and upon determining that (i) the entity to be excluded is not at the receiver location and not in the path and (ii) a measured power level at the receiver location does not exceed one or more permissible power levels for safe wireless power transmission, transmitting, by the transmitter, the power waves along the path to converge at the receiver location.

Abstract: 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.
