    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: 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: 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.
