摘要： The disclosure relates to a method for determining a level of a liquid in a tank with an ultrasonic fill state sensor and at least two reference surfaces for reflecting an ultrasonic wave transmitted by the ultrasonic fill state sensor. A first reference surface is arranged below a second reference surface. The method includes determining a first propagation speed of an ultrasonic wave to the first reference surface on a first measurement path and a second propagation speed from the first reference surface to the second reference surface on a second measurement path. The method also includes measuring a propagation time of an ultrasonic wave from the ultrasonic fill state sensor to a liquid level of the liquid in the tank, selecting the first propagation speed or the second propagation speed based on at least one selection criterion, and calculating a fill state using the propagation time measured.

摘要： The invention relates to an ultrasonic sensor with an adjustable detection range for use in gaseous media, preferably air. A threshold value generator generates threshold value curves that are fed to a comparator. The change in the detection range of the ultrasonic sensor, namely, the change in its switching point curve, is carried out by influencing the threshold value curves, whereby, in a selectable manner, the detection range can be adjusted either exclusively in the lateral extension of the sonic cone or else in the axial and lateral extensions of the sonic cone.

摘要： An airborne sonar collision avoidance system is disclosed. The system compensates for changes in temperature in real time to provide more accurate sonar detection. In addition, the sensors are arranged in a communications network that allows for the sensors to be programmed at run time, thus providing the ability to relocate the sensors without having to pre-program the sensors before the sensors are installed onto a different location.

摘要： An acoustic sound speed profiling system is provided. The system includes a sound emitter and a series of sensors or hydrophones spaced vertically in a water column. The sound emitter is a high-frequency sound source adap for mounting on the front end of a passive, towed sonar array. The sound source has a frequency which may be outside the acoustic aperture of the towed array. The series of sensors are located at intervals along and embedded within the array tow cable. The sensors are conventional hydrophones or thin-film hydrophone membranes. During operation of the system, the source transmits high frequency sound, which is received by each sensor along the tow cable of the towed array. Calculation of the speed of sound is determined from the position of the tow cable and the time-of-arrival of acoustic signals at each sensor. There is no interference with the normal operation of the passive towed array.

摘要： An ultrasonic ground speed sensor has a single transducer which both transmits and receives ultrasonic signals. The sensor is mounted on a vehicle in alignment with the direction of the vehicle, the transducer having a built-in angle with the body of the sensor unit. The transmitted signal is clocked by a 16 MHz clock, with the signal received by the transducer selectively filtered and amplified. A temperature sensor is also used to determine the speed of the transmitted and received signal. A 64-cycle sample period is used, as well as multiple counters and a signal processor to increase accuracy and minimize erroneous readings. A drop-out detector and monitoring system sensor is also described. The vehicle speed is calculated from a Doppler-based formula as a function of both the sum and difference of the transmitted and received signal frequencies. Also disclosed is a gasket seal having leak holes for drainage from the interior of the sensor.

摘要： A method for the position detection of the strip edge of a material web by means of an ultrasonic detector disposed in the strip edge region uses a transmitter 2 and a receiver 3, the received sound waves being transformed into an electric signal. To be sure to eliminate the influence of reflected waves on the measurement result, the transmitter 2 emits mutually time-shifted single pulses or wave packets. The wave packet (or single pulse) received by the receiver 3 is transformed into a corresponding electric oscillation packet, a limited area of the oscillation packet is scanned and the scan value is stored for further processing. An arrangement for the performance of the method comprises the transmitter 2 which is fed by a pulse train generator 4 the receiver 3 for delivering an electrical signal, an activatable peak rectifier circuit 6 connected to the receiver and an activatable transmission circuit 9 connected to the rectifier for transmission of the peak value to a memory.

摘要： Measurement apparatus utilizes a sonar head for sending and receiving sonar signals and the apparatus is calibrated before each measurement by locating the sonar head a fixed, predetermined distance from a stationary target. Movement of the sonar head is accomplished by a stepper motor and lead screw arrangement to position the sonar head the same, predetermined distance from the element to be measured as it was originally placed for calibration, and the difference between the calibration distance and the second distance is from a target motor and lead screw arrangement to position the sonar head the same, predetermined distance from the element to be measured as it was originally placed for calibration, and the difference between the calibration distance and the second distance is translated into a distance representing the desired measurement.

摘要： An improved method and apparatus for measuring the length of an open pipe includes a sound transducer placed in spaced open air communication with the interior of the pipe at a selected end. A logic circuit is employed with the transducer for producing a square wave sound pulse that is directed at the pipe's selected end. An oscillator provides an ambient temperature modified count in accordance with the time required for the pulse to travel the length of the pipe and return. For compensating for error tending to be introduced because of the spacing of the impedance reflective surface at the far end of the pipe, a standoff device establishes such a distance between the transducer and the selected end of the pipe as to effect an adjustment in the duration of the oscillator count that corrects for the error. In another embodiment a microprocessor is employed with the transducer to produce two successive square wave sound pulses to effect an adjustment in the count of an oscillator clock to avoid a false reading due to the above-mentioned spacing of the reflective surface. The amplitude of the greatest peak of the first pulse is measured. The gain of an amplifier is then adjusted to make a timer stop, modified in accordance with ambient temperature, during the reception of the echo from the second pulse when 40% of the amplitude of the peak echo is obtained.
