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 a power receiver circuit. A power receiver circuit may include power generating elements that may generate alternating current. The power receiver circuit may include group circuits that may connect power generating elements in parallel to combine the alternating current from the power generating elements into a single alternating current. The power receiver circuit may include rectifier circuits which may include rectifier channels connected to the group circuits and may include a rectifier that may generate direct current from alternating current. The power receiver circuit may include a step down converter connected to rectifier circuits that may convert direct current to direct current of a target voltage level. An output switch and linear regulator may be connected to the step down converter, and a microcontroller may be connected to the linear regulator and the output switch and may control the output switch.

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 trench cutting with laser machining. A laminate material including a conductive layer and a non-conductive layer may be cut with a first cut using a UV-laser. The cutting of a second cut, using the UV-laser, may be started at a top electrode of the non-conductive layer based on the location of the first cut, wherein the second cut is wider than the first cut. The cutting of the second cut may be stopped partially though the non-conductive layer. The stopping of the cutting of the second cut partially though the non-conductive layer may include stopping the cutting of the second cut before cutting a bottom electrode of the non-conductive layer.

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.
