摘要： A plurality of control points are defined having a known spatial relationship relative to an array of transducers. An amplitude is assigned to each control point. A matrix is produced containing elements which represent, for each of the control points, the effect that producing a modeled acoustic field having the assigned amplitude with a particular phase at the control point has on the consequential amplitude and phase of the modeled acoustic field at the other control points. Eigenvectors of the matrix are determined, each eigenvector representing a set of phases and relative amplitudes of the modeled acoustic field at the control points. One of the sets is selected and the transducer array is operated to cause one or more of the transducers to output an acoustic wave each having an initial amplitude and phase such that the phases and amplitudes of the resultant acoustic field at the control points correspond to the phases and relative amplitudes of the selected set.

摘要： The invention provides a method for improving the accuracy of level measurement by reducing or eliminating receive circuit saturation in ultrasound level measurement apparatus. The method involves adjusting the transmit power in order to control echo amplitude, in particular to avoid saturation, when the surface being monitored is within a pre-defined distance from the ultrasound transducer. The particular advantage of the invention is that it may be implemented without change to the electronic circuitry embodied in the apparatus.

摘要： An object detection apparatus of the present invention has a wave transmitter that transmits energy waves (ultrasound waves) to a detection target region. The object detection apparatus also has a wave receiver that receives the energy waves reflected from an object existing in the detection target region and converts the received energy waves to wave reception signals made of electric signals. The object detection apparatus further has a controller that controls the wave transmitter to continuously transmit the energy waves during a predetermined wave transmission period, and a measurement part that measures a distance from the object detection apparatus to the object based on the wave reception signals output from the wave receiver. The controller is configured so as to change the wave transmission period corresponding to the distance measured by the measurement part.

摘要： The exact spring height as well as the spring pressure can be determined with a single arrangement for the optimal utilization of the axle loads of a multi-axle air spring suspended vehicle and to control the distance between the chassis and the axle. An air spring (2) is equipped with an ultrasonic pulse/echo measuring system. The air spring (2) includes a transmitter/receiver component (14) arranged on the chassis and a first reference electrode (20) and a reflector component (16) fixed to the axle. The air spring height can be determined in a conventional manner from the relative value of the running times of the ultrasonic pulses which are traversed on the reference path and the measuring path. A second reference reflector (22) is mounted at a different distance to the first reference reflector (20). For the determination of pressure, the transmitting power or the receiving amplification of the second reference reflector (22) is controlled in such a manner that the amplitude (intensity) of the sonic waves, which are reflected from the first reference reflector (20), remains at a constant value. This amplitude (intensity) is measured via the sonic transducer (14).
