  • Patent number: 5712678
    Abstract: A method and apparatus are disclosed for scanning a surface of an object, transversely to a direction of motion. A scanner is provided for flying over the object at a flight altitude and flight velocity, having a system focal length, a scanning element rotating at a rotation speed which scans a surface over a scanning angle and a detector row, arranged at right angles to the scanning direction. A detector row is provided with a plurality of equal size individual detectors, which are capable of generating fundamental object pixels of a size which depends upon the distance from the object up to a maximum scanning distance. A standard object pixel, of a size corresponding to a fundamental object pixel, is driven at the maximum scanning distance. For each scanning sweep, via a sampling process, a uniform grid is formed which is composed of standard object pixels of a size corresponding to a fundamental object pixel at the maximum scanning distance in several lines and without gaps and/or overlaps.

  • Patent number: 5608628
    Abstract: A method and apparatus for recognizing a crash, in a vehicle by measuring vehicle speed change continuously within a limited time periods and comparing the measured values with those determined in prior time periods. Acceleration can be differentiated out by means of the above-mentioned process/arrangement and can be evaluated if, in the case of a high-speed and low-speed crash, it should not be possible to differentiate sufficiently by means of the partial speed difference. Different partial speed differences (by means of observation periods of different durations) can be measured and compared in order to permit ignition in the case of slower (oblique) crashes only within a limited time window in the initial phase of the crash.

  • Patent number: 5264694
    Abstract: In this optical imaging system the same object section is imaged by optical means on three spatially separate image planes. Surface sensors A, B, C of identical width which in turn comprise optoelectronic sensor elements arranged in the manner of a matrix are arranged in the three image planes at a distance from one another in parallel rows and are offset relative to one another from one row to the other. The three grids of surface sensors which are accordingly formed are offset relative to one another from one image plane to the other in such a way that the object section is detected without gaps by means of the surface sensors A, B and C during optical superposition. Thus, large surface area pictures with high resolution can be taken with the use of conventional surface sensors, e.g. of the CCD type. Due to the special arrangement of the surface sensors, three image planes with the corresponding optical means, e.g.

  • Patent number: 5262587
    Abstract: The present invention pertains to a clamping element for holding electronic boards inserted in parallel to one another into an electronic rack. The arrangement removes waste heat from the electronic boards to the rack housing by heat conduction and via heat exchangers. A clamping element is proposed for this purpose, which substantially reduces the thermal resistance and consequently the temperature difference caused by heat conduction between the electronic board and the housing rack, and which also permits variable, defined adjustable clamping forces, and which is designed as an optical clamping control indicator.

  • Patent number: 5216632
    Abstract: A memory arrangement that includes a static memory cell with two MOSFETs that are connected such that an input signal for setting the memory cell is applied to one MOSFET, and the output of the other MOSFET is connected to the input of the first MOSFET, so that one MOSFET is always conductive while the other is blocked. The two MOSFETs are connected with positive feedback. In each case, the gate electrode is connected to a voltage equal to half the battery voltage. The source electrode of the first (N channel) MOSFET forms the input of the memory cell. The drain electrode of the first MOSFET is connected to the source electrode of the second (P channel) MOSFET. The blocking resistance of the drain-substrate diode of the first MOSFET is greater than the blocking resistance of the source-substrate diode of the second MOSFET. Also, the output voltage of the first (N channel) MOSFET is greater than the sum of the gate voltage and the threshold voltage of the second (P channel) MOSFET.

  • Patent number: 5200015
    Abstract: A process for joining variously shaped vacuum heat insulating elements having edges adapted to be butted against each other or to overlap each other. A bellows is tightly connected with each vacuum heat insulating element in the area of its edges, the free edge of the bellows projecting beyond the element. The heat insulating elements are positioned such that the edges of the bellows rest against one another in an aligned manner or overlap, and the bellows are tightly connected with one another. The heat insulating elements are then moved against one another until their edges rest against one another or overlap, and are tightly connected with one another. The gap at the joint formed between the heat insulating elements and the bellows is evacuated and closed off tightly.
