Patent Images
1. A system, 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 waves;
a sender transducer coupled to the amplifier, the sender transducer adapted and configured to generate waves based on the electrical transmission signal received from the amplifier; and
a sender communications device adapted to receive input, the input including a power requirement; and
a sender controller coupled to at least one of the signal generator, the amplifier and the sender transducer and adapted to change a dwell time of the sender transducer based on the received power requirement.

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.
