1. A receiver device comprising:
a power receiver to receive a power beam to charge a power supply; and
a modulating reflector to reflect a portion of the power beam as a reflected signal, modulate the reflected signal, and vary a direction of the reflected signal to scan an area for a power beam transmitter device, wherein the power beam transmitter device is to track motion of the receiver device based on modulation of the reflected signal and to cooperate with other power beam transmitter devices to prioritize distribution of power among a plurality of receiver devices.
