Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 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 having a first phase based on the electrical transmission signal received from the amplifier; a sender c…
