摘要： 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.

摘要： Systems and techniques are provided for a self-powered energy harvesting circuit. A power generating mechanism may include power generating elements that generate alternating current signals. Rectifier circuits may each include a rectifier that generates a direct current signal from an alternating current signal. Group circuits may connect a group of the rectifier circuits in an electrical circuit to combine the direct current signals from the rectifier circuits in the group into a single direct current signal. Energy storage devices may be connected to the group circuits. The outputs of energy storage devices may be combined into a single output. The single output split into a primary output and a secondary output. A switch may be connected to the primary output. A controller may be connected to the secondary output and to the switch. The controller may control the switch. A voltage regulator may be connected to an output of the switch.

摘要： Systems and techniques are provided for a multichannel waveform synthesis engine. A phase counter module counts to a value corresponding to a number of phases available, outputs a phase counter value indicating a current phase, and resets the phase counter value when the phase counter value reaches a phase counter reset value. Several channels each output a waveform. Each channel includes a phase module that receives the phase counter value output from the phase counter module, and activates an activation signal when the phase counter value indicates a phase assigned to the channel from the number of phases available. Each channel includes a pulse width module that receives the activation signal, and when the activation signal is activated, activates a waveform for a period of time indicated by a pulse width assigned to the channel, and deactivates the waveform after the period of time indicated by the pulse width assigned to the channel.
