Abstract: 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.

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.

Abstract: A first controller can have a greater number of output lines than a second controller has input lines. The first controller can receive an ultrasonic transducer control signal and provide a first portion of the control signal to the first processor, where the length of the first portion is less than or equal to the number of input lines of the second processor. The first processor can send portions of the control signal to a plurality of second processors. Each of the plurality of second processors can have a number of input lines less than the number of output lines of the first processor. Portions of the control signal can be sent through the output lines of the first processor to the plurality of second processors at substantially the same time.

Abstract: An ultrasonic transducer having a membrane and a container having a base and at least one wall element. The one or more wall elements can be situated over at least part of the base to form a cavity that can have an at least partially open end. The open end can be sealed with the membrane and the interior of the container can be maintained at a lower atmospheric pressure than the ambient pressure. Within the container, a piezoelectric flexure can be fixed at one end to a location at a wall element. The other end of the flexure can be in mechanical communication with the membrane, either directly or through a stiffener that is itself in communication with the membrane.
