Abstract: In order to measure a reflecting structure on a volume layer, at least one sound or ultrasound wave packet is emitted by a transducer matrix (1a), which wave packet arrives at the layer (4) coherently. The echo signals on each element (1) of the transducer matrix are processed separately, signals corresponding to the echos of each individual volume element (4a) onto all the transducers of the matrix (1a) being determined on the basis of defined transducer-element/ volume-element-distances (rnm) by means of a correlating calculation. The two-dimensional velocity field of the structure in the layer (4) is furthermore determined by means of two or more transmitted wave packets and evaluation of the resultant phase differences and frequency differences. <IMAGE>

Abstract: A restrictor element (4) serves for measuring the amount of a flowing medium flowing through an advance pipe (1), the pressure differential occurring in the process being measured by a differential pressure sensor (6). The differential pressure sensor (6) and a temperature differential measuring element (9), which measures the temperature differential of the flowing medium in the advance pipe (1) and a return pipe (2), deliver signals to a computer (12). The computer (12) controls a drive (3), with the aid of which the restrictor element (4) is moved, so that different discretely stepped openings (5a, 5b) are switched into the flow path. As a result, different cross-sections become operative, so that the flow measuring device operates over a large measuring range with satisfactory accuracy. Such a device can be used, for example, to calculate heating costs. <IMAGE>

Abstract: The present invention discloses a method and a device for preventing thermal damage of workpieces due to heat developed by a grinding process. According to the method the temperature increase at the surface being ground is determined and the resulting actual value is compared to a reference value which has been established under the same grinding parameters with a grinding disk that caused thermic damage to the reference workpiece. During manufacture, the grinding process with the respective grinding disk is interrupted as soon as a temperature increase has been detected that corresponds to the respective temperature causing thermic damage. The reference value is determined such that it includes a certain safety margin. The determination of the actual value and the reference value may be accomplished by using geometric deformations of the workpiece that result from the temperature increase due to the grinding process. The device is characterized by special measuring devices for measuring the geometric deformations of the workpieces.

Abstract: In the case of a DC voltage supply, which is connected to a voltage source (U1), of an electronic ballast having a sinusoidal input current, the inrush current and the overvoltage are limited by a circuit arrangement. In this case, the voltage profile of the voltage source (U1) corresponds to a DC voltage or to a rectified mains voltage. During the switching-on (connection) process, an electronic switch (S1) which is provided in the circuit arrangement switches on and off periodically, or switches on at the zero crossing of the rectified mains voltage. If an overvoltage occurs on the voltage source (U1), the switch (S1) is opened again in order to protect the capacitor (C) and the output stage of the electronic ballast. <IMAGE>

Abstract: A process for the wireless transmission of data to a traffic sensor for assessing traffic in segments of a road network includes collecting data in a plurality of floating cars that travel in traffic and have sensor system for collecting the data. A current driving profile is formed in each floating car from the collected data. Actual values of characteristic driving profile properties are derived from the current driving profile and expected values of the characteristic driving profile properties are formed based on preestablished traffic situation information. A difference between the actual values and the expected values is determined and if the difference is determined to be a serious deviation from the expected values based on preestablished decision criteria, the data collected by the sensors is transmitted to a traffic center.
