Abstract: A pressure sensor having a diaphragm which is differently deformable or locally changeable by pressure differences is described. A construction advantageously usable even in poorly accessible spaces having high temperatures is obtained in that at least one functional section of the diaphragm has a material which has the properties of a black-body radiator or has an emissivity used for detection in the spectral radiation range corresponding to the temperature of the diaphragm under its conditions of use, and a radiation receiver unit, which detects at least a portion of the emitted radiation, having at least one infrared radiation sensor, is assigned to the diaphragm.

Abstract: The apparatus for control of a light-range of headlights of a motor vehicle includes two headlight orientation adjusting devices; at least one electro-optic sensor detecting actual values of light intensities of light reflected from an illuminated portion of the road; and an analyzer/control unit connected to the at least one electro-optic sensor and the adjusting devices to control the adjusting devices and the headlight orientation according to the sensor signal.

Abstract: A head lamp for motor vehicle dimming and fog lights having a reflector reflecting beams of a light source to form a light beam directed along a path, a diaphragm with an edge arrangable in the path, an achromatic lens arrangable in the path to portray an image of the edge as a light-dark border of the light beam on a roadway and a correction element arrangable in the path to at least reduce a color fringe otherwise present on the light-dark border of the light beam from chromatic aberration.

Abstract: A headlight arrangement for vehicles, particularly for power vehicles, comprises a light source with a light reflector forming a light beam which illuminates a roadway with a predetermined light distribution, and at least one adjustable element for changing the light distribution.

Abstract: Speech versus music is decided by comparing the presence of pauses greater than 32, 60 and 500 ms in the lower input spectrum, and 4 ms in the higher input spectrum.

Abstract: A succession of film frames is continuously transported past at least one row of optoelectronic converters. The information registered by the row of optoelectronic converters is periodically read out and written-in into a storage. The information stored in the storage is read out at a rate and in a sequence converting the information in the storage into television signal picture information.
