Publication number: 20190097473Abstract: 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.Type: ApplicationFiled: November 27, 2018Publication date: March 28, 2019Inventors: Andrew Joyce, Paul Reynolds

Patent number: 10233076Abstract: Systems and techniques are provided for transducer array subdicing. A laminate material may include two laminate material flexures which each have a flexure boundary defined by a gap in the piece of laminate material. A trench may be located between the two flexures. The trench may be defined by a removal of a portion of laminate material from the piece of laminate material. A second trench may be on an opposite surface of the piece of laminate material from the trench. The second trench may be partially aligned with the trench. The trench and the second trench may result from the removal of laminate material from the piece of laminate material to a depth of 20% to 60% of the thickness of the piece of laminate material.Type: GrantFiled: May 13, 2016Date of Patent: March 19, 2019Assignee: uBeam Inc.Inventor: Andrew Joyce

Patent number: 10230271Abstract: 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.

Patent number: 10148131Abstract: 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.Type: GrantFiled: July 22, 2015Date of Patent: December 4, 2018Assignee: uBeam Inc.Inventors: Meredith Perry, Paul Reynolds, Sean Taffler, Andrew Joyce

Patent number: 10149391Abstract: 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.Type: GrantFiled: March 8, 2016Date of Patent: December 4, 2018Assignee: uBeam Inc.Inventors: Nicholas Lavada Nemeth, Adam Stephen Elhadad, Andrew Joyce, Sean Taffler
