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: An interferometric measuring device for recording the shape, the roughness or the clearance distance of the surface of a measured object is provided, the measuring device having a modulating interferometer, to which is supplied short-coherent radiation by a radiation source, and which has a first beam splitter for splitting the radiation supplied into a first beam component guided via a first arm, and into a second beam component guided via a second arm. One beam is shifted with respect to the other beam, with the aid of a modulating device, in terms of the beam's light phase or light frequency, and passes through a delay line. The two beams are subsequently combined at an additional beam splitter of the modulating interferometer.

Abstract: A headlight illumination field regulating apparatus includes an electromagnetic radiation emitter, a reflected radiation sensor, an evaluation unit, and a unit for adjusting the alignment position of the headlights. The electromagnetic radiation emitter operates to radiate electromagnetic radiation on the road to the front of the automobile and the reflected radiation sensor senses reflected radiation and creates a data point representative of the irradiated spot. The evaluation unit evaluates the data points to establish the position of the detected spot or area and thereafter compares the evaluated position with a predetermined desired position and subsequently generate a correction signal to control the regulation or adjustment of the headlights into a proper light projecting orientation which ensures a proper projection limit of the beam of the headlight.

Abstract: A headlight illumination field regulating apparatus includes an electromagnetic radiation emitter, a reflected radiation sensor, a comparing element, and a unit for adjusting the alignment position of the headlights. The electromagnetic radiation emitter operates to radiate two electromagnetic radiation beams on the road to the front of the automobile and the reflected radiation sensor senses reflected radiation and determines a relationship of a sensed characteristic of the first radiation beam and a sensed characteristic of the second radiation beam and creates a data point representative of the irradiated spot. The comparing element thereafter compares the determined relationship between the sensed reflected radiation characteristics with a predetermined desired position and subsequently generate a correction signal to control the regulation or adjustment of the headlights into a proper light projecting orientation which ensures a proper projection limit of the beam of the headlight.
