Abstract: PCT No. PCT/DE94/01134 Sec. 371 Date Apr. 4, 1996 Sec. 102(e) Date Apr. 4, 1996 PCT Filed Sep. 27, 1994 PCT Pub. No. WO95/10434 PCT Pub. Date Apr. 20, 1995The invention relates to a device for the automatic control of a windscreen wiper motor. The device has a moisture sensor which emits a signal depending on the moisture on the windscreen or another point on a motor vehicle so that this signal to some extent produces an analog reflection of the moisture varying in time. The output signal of the sensor is evaluated in such a way that it is continuously compared with a threshold value which can be altered. Every time this threshold value is reached or exceeded by a pulse-like change in the sensor output signal, this event is counted. After a given number Z of such events the windscreen wiper motor is switched on.
Patent DE-4335857-A1 (DE)
Inventor: GERSTER CHRISTIAN PROF
IPC: H02M1/088
Filed: 1993-10-21
Abstract: A method and a device are specified for driving a series circuit of power semiconductor switches (2). In this case, the voltage load on the individual switches in the series circuit is compensated for in that the voltage (Uce1 ... Ucen) across each switch in the series circuit is measured as the control variable and the switching times are changed on the basis of this measured voltage such that the voltage load is essentially of equal magnitude for all the switches during switching. In addition, the measured voltage can be used to influence the magnitude of the control voltage (Ugeoff1 ... Ugeoffn) in the switched-off state such that the voltages across the switches when they are switched off are essentially of equal magnitude. The advantage of the invention can be seen in the fact that the voltage load on the individual semiconductors can be compensated for not only during switching but also when they are switched off. In addition, the regulation also compensates for influences of parameter differences and changes as well as influences from the circuitry. In consequence, the switches can be used optimally in terms of both power and frequency. <IMAGE>

Filed: 1994-05-26
Abstract: The present invention relates to a microvalve which can be used, in particular, as a pilot valve in pneumatic control systems. The solenoid valves used hitherto in this area can be miniaturised only at the expense of a considerable increase in costs. The microvalve according to the invention comprises a first, discharge-side part (1) with a diaphragm structure (3) as a movable closing element and a second part (2) with an outlet opening (7) and a valve seat (5). The diaphragm structure is provided with heating elements so that, upon heating, the diaphragm flexes counter to the applied pressure. At least one of the two parts has pits of defined depth (6), which are arranged in such a way that, when the valve is closed, cavities are formed which are heated by the heating elements. To assist the opening functions of the valve, the diaphragm can be coated with a material which has a different thermal coefficient of longitudinal expansion than the diaphragm material. The microvalve described can be manufactured at a reasonable cost using semiconductor technology and its combined thermomechanical/thermopneumatic action provides improved operating characteristics. <IMAGE>

Title: Cubic sensor for non-directional measurement of equivalent electric field strength
Inventor: BAHMEIER GEORG DIPL ING
IPC: G01R29/08
Filed: 1994-08-10
Abstract: Earlier sensors for measuring equivalent electric field strength have been, because of their external shape, not ideally non-directional, unwieldy or difficult to produce. The novel sensor is, in contrast, almost ideally non-directional, relatively small and offers advantages in production. The sensor consists of a metallic cubic housing having a flat measuring electrode on each side. By virtue of the shape of the sensor and of the measuring electrodes, the electric field is resolved exactly into its three orthogonal components. The RMS values of the three field components are measured using the sensor. The overall RMS value, which is identical to the equivalent electric field strength, is formed from the three measured values. The sensor is suitable, because of its non-directionality and its small overall size, above all for use in portable field-strength measurement systems in the frequency range of up to 200 MHz. Such measurement systems are required, for example, for health and safety at work. <IMAGE>
