Abstract: Systems and techniques are provided for beamforming for wireless power transfer. A position of a second wireless power transfer device relative to a first wireless power transfer device may be determined. A beam may be simulated as being transmitted from the position of the second wireless power transfer device. Phases of a wave front of the simulated beam that would be received by elements of the first wireless power transfer device may be determined. A control signal for each of the elements for which phases were determined may be generated based on the determined phase of the wave front that would be received at the element. The control signal for each of the elements for which phases were determined may be supplied to the elements for which phases were determined. A waveform may be transmitted from the elements for which phases were determined based on the supplied control signal.

Abstract: Systems and techniques are provided for performance adjustment for wireless power transfer devices. A wireless power transfer device may be activated. A characteristic of the performance of the activated wireless power transfer device may be measured. It may be determined that the measured characteristic of the activated wireless power transfer device does not meet a performance requirement for the wireless power transfer device. An adjustment to be applied to the wireless power transfer device may be determined. The adjustment may be based on determining that the measured characteristic of the activated wireless power transfer device does not meet the performance requirement for the wireless power transfer device. The adjustment may be applied to the wireless power transfer device.

Abstract: An ultrasonic transducer having a container, a base an actuator and a membrane system. The membrane system can include a membrane, a mesa and a standoff. The mesa can be shaped to achieve one or more target frequencies and other target vibrational properties, such as amplitudes. The actuator may be a flexure having one or more electroactive materials, such as piezoelectric and/or electrostrictive materials. The flexure may be fixed at one end to a wall of the container be in communication with the membrane system at or around its other end. The actuator may be in contact with the membrane system through the mesa and/or the standoff. The standoff may include an adhesive filled with beads to achieve a specific thickness.

Abstract: Systems and techniques are provided for an ultrasonic electrostatic device. A device may include a substrate comprising an indentation. A first electrode may be located within the indentation. A membrane may be affixed to the substrate and may cover the indentation. The membrane may include a second electrode. The first electrode and the second electrode may be electrically connected to a circuit such that the first electrode and the second electrode form a parallel plate capacitor.

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.
