First Claim
Patent Images
1. A method for controlling power distribution, comprising:
- requesting a first receiver of a plurality of receivers having a plurality of load resistances, respectively, within a charging region of a transmitter, the first receiver having a first load resistance, to modify the first load resistance to a value that achieves a target power distribution among the plurality of receivers; and
transmitting power wirelessly within the charging region.

Abstract
Exemplary embodiments are directed to power distribution among a plurality of receivers. A method may include requesting at least one receiver of a plurality of receivers within a charging region of a transmitter to modify an associated load resistance to achieve a desired power distribution among the plurality of receivers. The method may further include requesting each receiver of the plurality of receivers to modify an associated load resistance to achieve a desired total impedance as seen by the transmitter while maintaining the desired power distribution among the plurality of receivers.
