SYSTEM AND METHODS FOR USING SOUND WAVES TO WIRELESSLY DELIVER POWER TO ELECTRONIC DEVICES

Abstract:

A method for wireless charging of a game controller includes connecting a pocket-forming transmitter to a power source; generating sound waves from a sound circuit embedded within the transmitter; controlling the generated sound waves with a digital signal processor in the transmitter; transmitting the sound waves through antenna elements connected to the transmitter to a receiver configured to capture the sound waves forming a pocket of energy in 3-D space at the receiver with antenna elements connected to the game controller; and converting, by a plurality of sensor elements included in the receiver, the pocket of energy into a DC voltage for charging or powering a battery of the gamer controller. A respective one of the plurality of sensor elements produces an electrical analog output signal proportional to the controlled sound waves captured.
