Abstract: A device and a method for detecting an actuator by sonicating the actuator with sound waves through a sensor. The device is used in particular in a safety application. The sensor and actuator can be moved relative to each other. The sensor includes a sound wave transmitter, a sound wave receiver and a computing unit. The sound wave transmitter is designed to send sound waves in the direction of the actuator. The sound wave receiver, in turn, is designed to pick up the sound waves reflected by the actuator and convert them into an analog signal. The computing unit converts the analog signal into a digital signal and detects the actuator by comparing it with a reference signal.

Abstract: A method of fabricating a binary metasurface for producing an ultrasound Airy beam for underwater ultrasound applications is provided. The method includes generating an amplitude distribution of an Airy beam at a frequency, and converting the amplitude distribution into a binary phase profile. The method also includes generating a 3D printing design of a binary metasurface based on the binary phase profile, wherein the binary metasurface includes ridges and grooves defined by neighboring ridges, a ridge having a thickness corresponding to a phase delay of π/2 of the Airy beam between water and a 3D-printable material. The method further includes additively manufacturing the binary metasurface with the 3D-printable material based on the 3D printing design.

Abstract: An ultrasonic sensor includes: an ultrasonic element provided to transmit or receive an ultrasonic wave propagating along a directional axis; and an element housing case that includes a case diaphragm having a thickness direction along the directional axis. A resonant space is defined between the case diaphragm and the ultrasonic element for the propagating wave, by housing the ultrasonic element while separating the ultrasonic element from the case diaphragm. A horn shape is defined in the element housing case in which a width of the resonant space in a direction orthogonal to the directional axis is reduced as the resonant space extends in an axial direction parallel to the directional axis.

Abstract: Circuitry for ultrasound devices is described. A multi-level pulser is described, which can support time-domain and spatial apodization. The multi-level pulser may be controlled through a software-defined waveform generator. In response to the execution of a computer code, the waveform generator may access master segments from a memory, and generate a stream of packets directed to pulsing circuits. The stream of packets may be serialized. A plurality of decoding circuits may modulate the streams of packets to obtain spatial apodization.

Abstract: An acoustic, preferably ultrasonic, wave emission and/or reception device, including a wave emitter configured to transmit waves at an emission frequency, and a receiver of preferably ultrasonic waves, separate from the emitter, having a resonance frequency, and configured to receive waves generated by the emitter and including direct waves and reflected waves, wherein the device includes a resonance frequency modulator of the receiver and a control unit configured to control the resonance frequency modulator during a predetermined time period, so as to reduce the sensitivity of the receiver during the predetermined time period by moving the resonance frequency of the receiver away from the emission frequency of the emitter. The acoustic device relates to the field of ultrasonic sensors, particularly PMUTs or CMUTs, having a high quality factor.

Abstract: A system and method from improving the image quality achievable with an ultrasound transducer by using a composite aperture for receiving ultrasound echoes. By using two receive cycles per vector, twice as many transducers may be used for receiving ultrasound imaging data than there are physical channels available in the ultrasound probe. An ultrasound probe utilizing a composite aperture can achieve high image quality from a system have reduced power, size, cost and complexity.

Abstract: A system is provided for imaging an underwater environment. The system includes one or more arrays of transducer elements. Each array is operated at a fixed phase shift and varies in frequency so as to beamform multiple sonar return beams of a first range of angles and a second range of angles. The arrays can be oriented to cover the gap in sonar coverage for other arrays to create a continuous arc of sonar coverage. Accordingly, a 2D live sonar image can be formed. Three arrays are mounted in a housing in an X plus Line configuration with one of the arrays extending below the center of the X.
