Abstract: An electronic power supply that converts alternating current to a regulated DC voltage with high efficiency is accomplished by an AC-DC converter (10) having a switch (26) that connects the input AC power source directly to the DC output filter capacitor when the input voltage is substantially equal to the output voltage, and the output voltage is less than a set value. This power supply can be used with low impedance AC power sources capable of providing high surge currents such as commercial utility lines. <IMAGE>
Patent DE-3730181-A1 (DE)
Inventor: REHAK MANFRED
IPC: H04N5/21
Filed: 1987-09-09
Abstract: 2.1 In band-limited frequency-modulated transmission systems such as the transmission of television signals via satellites, a dispersal signal is superimposed onto the television signal to be transmitted before it is frequency-modulated. This leads to disturbances in satellite television receivers. In a known circuit, a correction signal characterising the amplitude of the dispersal signal is generated by evaluating the synchronisation signals and this correction signal is additively superimposed on the input signal. The novel circuit should also provide for compensation of the disturbances caused by the dispersal signal if no standard-oriented synchronisation signals are available. 2.2 This is achieved by means of a circuit which generates overshoots on a reference level of the signal. These overshoots, which differ from the useful signals with respect to their level are evaluated with respect to amplitude and used for generating the correction signal. 2.3 Satellite television receiver. <IMAGE>

Title: Ultrasonic tomography device
Inventor: NEWERLA KLAUS
IPC: G01S7/52
Filed: 1988-08-01
Abstract: For producing a tomographic ultrasonic sectional image a plurality of B scans have to be superposed which were obtained from different angular directions. These different aspect angles are implemented by means of four linear ultrasonic transducer arrays (2i) which are arranged around an object under examination (6) in the shape of a square and are driven one after the other in terms of time. Before the superposition can take place the B scans which are present in each case in relative coordinates (xi, yi) have to be recalculated (converted) into the stationary coordinate system (x, y) of a monitor (10). According to the invention, for this coordinate transformation an analog calculation circuit (20) is provided with two analog multiplexers (22 and 28) as well as two operational amplifiers (42 and 44) by means of which the relative coordinates (xi, yi) are optionally reversed and inverted. The picture is shown on a monitor (10) which has separate inputs for brightness (z) and the horizontal (line) deflection (x) and vertical deflection (y). As a result, the time needed for calculating the coordinate transformation becomes virtually negligible and the real-time graphical presentation of tomographic ultrasonic sectional images becomes possible. <IMAGE>

Title: Method for conveying heat from the earth's interior to the earth's surface and use of a thermopipe known per se
Inventor: KRUESS HARTMUT DIPL ING
IPC: F28D15/02
Filed: 1988-10-01
Abstract: The present invention relates to a method for conveying heat from the earth's interior to the earth's surface. This object is achieved by the method and by using a thermopipe known per se. In the prior art, there have repeatedly been problems with the pump system which is required to pump the water, employed as energy carrier, in a circuit. The invention remedies this by providing fluid medium in the lower region of a thermopipe reaching into the earth's interior and known per se and applying to the pipe such a vacuum that the fluid medium is converted into the gaseous state and maintained therein, in which the evaporation heat is permanently supplied by heat from the earth and is permanently discharged in the upper region of the pipe by a heat exchanger. <IMAGE>

Patent DE-3840762-A1 (DE)
Title: Method and device for scanning a terrain surface
Inventor: HOFMANN OTTO DR
IPC: G01C11/02
Filed: 1988-12-03
Abstract: The invention relates to a method and a device for scanning the terrain surface and/or other objects transversely to the direction of flight by means of a detector row which contains a number (M) of equally large single detectors. According to the main application, equally large standard object pixels are generated distance-independently from the elementary object pixels, which become larger with distance, by means of an integration and resampling process. For short distances (e.g. at the nadir point), a relatively large number (M) of single detectors is needed in consequence. The resampling process is distance dependent and thus also flight-altitude dependent and scanning and pixel rate must be changed in dependence on flight altitude and speed. According to the invention, these disadvantages are eliminated by a variable system focus (F) and variable rotational speed (U) of the scanning element in that they are controlled as a function of the flight altitude (h)/flying speed (v) ratio. The image data stream and the standard object pixel size are also functions of this ratio. This method is implemented by a multi-element lens or mirror optics system (S), the spacings of which are controlled as functions of the h/v ratio. The advantages of this method consist in that the resampling process remains constant for all recording altitudes, that a lower number (M) of detectors is needed and that the pixel rate, and thus the band width, of the ...

Title: Navigation method with an integrated navigation system and a magnetic sensor for freely navigating transport vehicles in the industrial field
Inventor: HIPP JOHANN DIPL PHYS
IPC: G05D1/02
Filed: 1989-04-05
Abstract: The positional error of an integrated navigation system increases with increasing time and increasing distance travelled. In the case of free navigation in the industrial field, the travel course stored in the vehicle must always be maintained within a specific tolerance, on grounds of safety. For this purpose the invention provides that small magnets let into the track non-uniformly be used for the absolute updating of the integrated navigation system. A magnetic sensor, with which the position of the magnets relative to the vehicle is measured, is fitted on the vehicle. From this measurement and the integrated navigation position of the vehicle, positional values are yielded for the magnets which are compared in the vehicle computer with the information stored in the vehicle. From the comparison, the absolute accumulated positional error of the integrated navigation system is determined and a corresponding updating is carried out for the purposes of correction. At the beginning, the position of the magnets is measured by the vehicle in a learning journey and stored. The information content about the travel course and the magnet positions can be extracted and used for other vehicles.
