摘要： An ultrasonic measuring device includes an ultrasonic transducer without voltage converter having two transducer terminals to which an alternately reversible control voltage can be applied for emitting an ultrasonic burst signal in a control phase and to which an evaluation voltage is applied in a reception phase. The ultrasonic transducer decays in a decay phase between the control phase and the reception phase. A control unit generates the control voltage. The control unit comprises a full bridge circuit with two half bridge circuits, each comprising two semiconductor driving switches, which are connected to the two terminals of the ultrasonic transducer. An evaluation unit is provided with two input terminals, each of which is connected to the terminals of the ultrasonic transducer via a connection line. Voltage limiting elements in the two terminal lines limit the voltage applied to the input terminals of the amplifier.

摘要： A proximity sensing function is implemented using a collection of core independent peripherals (CIPs) in a microcontroller without software overhead to the central processor during operation thereof. A pulse width modulation (PWM) peripheral generates a high frequency drive signal that is on for a short duration to an ultrasonic transmitting transducer. An ultrasonic receiving transducer receives reflected ultrasonic pulses during an integration time window. The received pulses are detected and integrated into a voltage value. The integrated voltage value is compared to a prior voltage value average, and if different, generates a proximity sense signal of an object. Direction, distance and speed of the object may also be determined from the voltage values.

摘要： In a method and system for inspecting the condition of a structure, the structure is scanned with a three-dimensional (3D) scanner. The 3D scanner includes a sensing system having one of a radar sensing device or an ultrasonic detection device. The sensing system detects 3D information about a subsurface of the structure, and the 3D scanner generates 3D data points based on the information detected by one or more of the radar sensing device and the ultrasonic detection device. A 3D model is constructed from the 3D data and is then analyzed to determine the condition of the subsurface of the structure.

摘要： A sonic level measuring method comprises steps of disposing N sonic receivers 51,52,53, . . . 5n at a constant interval l toward a water surface along the longitudinal portion of a waveguide tube, oscillating sonic pulses to detect the number Nnull of the sonic receivers and computing an interval Lnullnull(Nnullnull1) l between a sonic receiver 5null that is positioned on the original point for the water level measurement, measuring a transit time 1 t 1 = l C that it takes for the sonic pulse to be transited between a sonic receiver 5null-1 and the sonic receiver 5i, measuring a transit time 2 t 2 = 2 null null null null null L C from the receiving moment of the advancing sonic pulse until the sonic pulses are reflected on the water surface and then again received by the sonic receiver 5i, computing an interval nullL between the sonic receiver 5null and the water surface, adding the interval nullL to Lnull and obtaining a distance LxnullLinullnullL thereby to measure the water level.
