Patent abstract

A vehicle powering wireless receiver for use with a first electromagnetic resonator coupled to a power supply. The wireless receiver including a load configured to power the drive system of a vehicle using electrical power, a second electromagnetic resonator adapted to be housed upon the vehicle and configured to be coupled to the load, a safety system for to provide protection with respect to an object that may become hot during operation of the first electromagnetic resonator. The safety system including a detection subsystem configured to detect the presence of the object in substantial proximity to at least one of the resonators, and a notification subsystem operatively coupled to the detection subsystem and configured to provide an indication of the object, wherein the second resonator is configured to be wirelessly coupled to the first resonator to provide resonant, non-radiative wireless power to the second resonator from the first resonator.
