Abstract: An ultrasonic device includes a substrate and a support member. The substrate has an element array including a plurality of ultrasonic transducer elements arranged in an array form. The support member has a surface adhered to the substrate in an area including the element array, and an opposite surface opposite from the surface adhered to the substrate, a distance from the surface adhered to the substrate to the opposite surface being different with respect to two adjacent ones of the ultrasonic transducer elements in the element array.

Abstract: Techniques are disclosed for systems and methods to provide transmission signal shaping for transmission signal-based sensor systems, such as radar and/or sonar sensor systems. A low noise signal shaping transmitter includes a digital to analog converter configured to convert a digital shaping control signal to an analog shaping control signal, a signal shaping circuit configured to convert the analog shaping control signal into a shaped voltage, and a power amplifier configured to provide a shaped transmission signal based on the shaped voltage and a digital transmission control signal. Each element of the transmitter may be formed from relatively slow switching analog and/or digital circuitry components. Resulting shaped transmission signals may be used to excite radar antennas, sonar transducers, sound cells, and/or other elements of sensor systems.

Abstract: A sound baffle device for use with an acoustic sensor deployed in a housing by a deployment line comprises a radially extending baffle plate and an affixing mechanism for affixing the baffle plate to the deployment line. The baffle plate is configured to reduce acoustic transmission between a first zone of the housing on one side of the baffle plate and a second zone of the housing on an opposite side of the baffle plate.

Abstract: Implementations of the present invention relate to devices, systems, and methods for isolating electronic components from input vibrations. The vibration isolation device may passively isolate the housed electronics from substantially all input vibrations. The vibration isolation device may include elastic members to suspend the electronic components within a support frame such that input vibrations are unable to directly influence the electronic components.

Abstract: Example embodiments include a method of reducing noise include forming a main signal and one or more reference signals at a beam-former based on at least two received audio signals, detecting voice activity at a voice activity detector, where the voice activity detector receives the main and reference signals and outputting a desired voice activity signal, adaptively cancelling noise at an adaptive noise canceller, where the adaptive noise canceller receives the main, reference, and desired voice activity signals and outputs an adaptive noise cancellation signal, and reducing noise at a noise reducer receiving the desired voice activity and adaptive noise cancellation signals and outputting a desired speech signal.

Abstract: A compact omnidirectional antenna for dipping sonar comprises multiple elementary transmission rings formed around a longitudinal axis of the antenna and multiple hydrophones distributed around the longitudinal axis, the antenna intended to be dipped in water, the hydrophones separate from the elementary transmission rings, the hydrophones and the elementary transmission rings fixed in the antenna. The elementary transmission rings and the hydrophones are interlinked along one and the same height (H) measured along the longitudinal axis.

Abstract: The present disclosure relates to a method for manufacturing an ultrasonic transducer by exciting the sound wave via an electromechanical transducer disposed on a sensor body, determining a current propagation velocity of the sound wave on an exit surface of the sensor body, determining the difference between the current propagation velocity and the desired propagation velocity of the sound wave on the exit surface, determining difference between speed of sound in the sensor body and a desired speed of sound, removing material in the region of the exit surface of the sensor body, wherein the remaining material is dimensioned such that the current propagation speed of the sound wave on the exit surface of the sensor body, and/or the delay caused by the speed of sound in the sensor body, at least approximately agrees with the desired propagation speed of the sound wave on the exit surface.
