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.
Claims9
A system, comprising:
- a sender comprising:
- a signal generator;
- an amplifier coupled to the signal generator, said amplifier configured to receive power from a power source and to generate an electrical transmission signal adapted to be used to generate ultrasonic waves;
- a sender transducer coupled to the amplifier, the sender transducer adapted and configured to generate ultrasonic waves having a first phase based on the electrical transmission signal received from the amplifier;
- and
- a sender controller coupled to at least one of the signal generator, the amplifier and the sender transducer and adapted to change the first phase to a second phase based on at least one received configuration parameter associated with phase and to change a dwell time of the sender on the receiver based on a received power requirement;
- and
- a receiver comprising:
- a receiver transducer adapted and configured to receive ultrasonic waves generated by the sender transducer and to generate a receiver electrical signal based on the received ultrasonic 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 controller coupled to at least one of the receiver transducer and the receiver electrical storage device, and
- a receiver communications device adapted and configured to communicate with a sender communications device wherein the communication includes a configuration parameter selected from a group consisting of:
- a configuration parameter associated with phase and a power requirement.
