Abstract: A method and system for generating transmit pulses for use with an electrostatic transducer in harmonic imaging are provided. The excitation waveforms are pre-distorted to account for the non-linear output of the electrostatic transducer. Additionally, the force on a multiple element electrostatic transducer array is measured. A bias voltage is applied to the electrostatic transducer where the bias voltage is responsive to the measured force.

Abstract: Ultrasonic vibrators, attached to the back of a mirror, are vibrated according to an A.C. signal pattern which is selected from various A.C. signal patterns for the removal of water, frost and/or ice from the surface of the mirror. Further included is a temperature detecting device attached to the back of the mirror for inhibiting operation of the ultrasonic vibrators when the temperature of the mirror exceeds a predetermined temperature, to thus avoid thermally-induced damage to the mirror.

Abstract: An apparatus includes an array of pixels, each pixel including in-cell pixel logic and a piezoelectric micromechanical ultrasonic transducer (PMUT) element, each in-cell pixel logic being communicatively coupled with at least one adjacent pixel in the array. Transceiver electronics may operate the array in a selectable one of a first mode and a second mode. In the first mode, the array may generate a substantially plane ultrasonic wave. In the second mode, the array may generate, from at least one superpixel region, a focused beam of relatively high acoustic pressure, each superpixel region including at least one inner pixel disposed in a central portion of the superpixel region and at least a first group of outer pixels disposed in an outer portion of the superpixel region. The transceiver electronics may be configured to operate the array by configuring at least one in-cell pixel logic.
