Abstract
A wireless power distribution system and method for power tools and other battery-powered devices. The system includes a power transmitter configured to transmit a power signal within a first power distribution volume and a plurality receivers configured to receive the power signal. The receivers include power harvesters, batteries, light sources and light sensors. The receivers determine whether the received power signal is greater than a power threshold value and convert the RF power signals into direct current. The direct current is used to charge a battery, power the light source, etc. The light source selectively receives power from the battery when the ambient light, detected by the light sensor, is below a light threshold value.
