Abstract: An array of ultrasonic transducers can be controlled to produce a steerable beam. Beam steering can be skewed by buffer delays in the distribution of a clock signal. The skew can be at least approximately linearized by distributing the clock signal in a diagonal fashion across an array of buffers corresponding to ultrasonic transducer controllers. Potential error in beam steering that can arise from clock skew can be corrected based on the linear tilt.

Abstract: Systems and techniques are provided for beamforming for wireless power transfer. A phase/amplitude map for a notional field in a plane of an aperture of the second wireless power transfer device may be determined. A Fourier transform may be performed on the phase/amplitude map for the notional field to generate a spatial frequency representation of the notional field. A phase/amplitude map for a second notional field in a plane of an aperture of the first wireless power transfer device may be determined based on the spatial frequency representation of the notional field and the position of the second wireless power transfer device. Control signals for transducer elements of the first wireless power transfer device may be generated based on the determined phase/amplitude map for the second notional field. The control signals for the transducer elements may be supplied to the transducer elements.

Abstract: Systems and techniques are provided for laminate material bonding. A bonding agent may be applied to a first layer. A second layer may be placed onto the bonding agent on the first layer to form a laminate material. The laminate material may be placed between a first piece of non-compliant material with a first piece of compliant material and a second piece of non-compliant material with a second piece of compliant material. The laminate material may be in contact with the first piece non-compliant material and the second piece of non-compliant material. Pressure may be applied to the laminate material by applying pressure to the first piece of compliant material for a curing time of the bonding agent.

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: 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: 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.
