RECEIVER TRANSDUCER FOR WIRELESS POWER TRANSFER
First Claim
Patent Images
1. A system, comprising:
- a receiver transducer adapted and configured to receive waves generated by a sender transducer of a sender and to generate a receiver electrical signal based on the received waves;
a receiver electrical storage device adapted and configured to store electrical energy based on the receiver electrical signal generated by the receiver transducer;
a receiver communications device adapted and configured to send input to the sender, the input comprising a power requirement that causes the sender to change a dwell time of the sender on the receiver.

Abstract
A signal generator generates an electrical signal that is sent to an amplifier, which increases the power of the signal using power from a power source. The amplified signal is fed to a sender transducer to generate ultrasonic waves that can be focused and sent to a receiver. The receiver transducer converts the ultrasonic waves back into electrical energy and stores it in an energy storage device, such as a battery, or uses the electrical energy to power a device. In this way, a device can be remotely charged or powered without having to be tethered to an electrical outlet.
