Abstract: An ultrasonic transducer that can include a driver side and a bias voltage side. A higher voltage source can be electrically connected to the bias voltage side through a first resistor. A lower voltage source can be electrically connected to the driver side of through a second resistor. A field effect transistor or other suitable switch can be included, having a source, a gate and a drain. The source can be electrically connected to ground and the gate can be electrically connected to a control signal source. The drain can be electrically connected to the lower voltage source through a second resistor and be electrically connected to the driver side of the ultrasonic transducer. The gate can be electrically connected to a signal source through a third resistor.

Abstract: 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.

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: Systems and techniques are provided for membrane bonding. A photoresist may be applied to an ultrasonic device. A portion of the photoresist may be removed. A bonding agent may be applied a portion of the photoresist that is not removed. A membrane may be placed on the ultrasonic device such that the membrane is in contact with the ultrasonic device through the bonding agent and the photoresist. The membrane and the ultrasonic device may be placed in between a first flat plate and a second flat plate, such that the second flat plate rests on top of the membrane. Light pressure may be applied to the membrane. The light pressure may be applied by one or more of the weight of the second flat plate and a pressure providing device applying pressure to either or both of the first flat plate and the second flat plate.

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.
