The integrated sensor circuit is electroconductively connected to at least two electrode terminals (10) guided through the base (2). A protecting cap (11) made from expandable material and overreaching the semiconductor chip (5) with the integrated sensor circuit is permanently fixed to the base (2) of the sensor component (1), the protecting cap (11) being shaped or arranged so that when placing or fastening the protecting cap (11) on the base (2), the fixing element (8) which projects beyond the periphery of the chip carrier (4) is freed.
Patent DE-19639263-A1 (DE)
Title: Method for handling goods with vacuum lifting device
Inventor: SCHMIDT WERNER
IPC: B66C1/02
Filed: 1996-09-25
Abstract: The method involves ensuring that the earliest time (t1) that a vacuum lifting device can raise a load occurs after the rate of vacuum loss in the vacuum has reached zero (VB to V0). The lifting action will only take place if the vacuum pressure is above a set minimum negative pressure (VE). The variation in the vacuum pressure (VN) over time is measured by a control mechanism which gives a signal when the various threshold values are reached. If a subsequent loss in vacuum pressure occurs, an emergency vacuum generator can be operated by the control mechanism as soon as a drop in vacuum occurs (V1,V2,V3) and before the minimum is reached.

Patent DE-19642712-A1 (DE)
Inventor: MEHLHORN HEIDRUN
IPC: G01N21/89
Filed: 1996-10-16
Abstract: The method for measuring and evaluation of surface effects is executed using one line measuring of effects at three measuring points by CCD matrix cameras (1, 2, 3), directly after the mechanical treatment of the textile line. The textile line is led over a pointed measuring edge (14). The supply to and the delivery from the edge, results in different angles (alpha and beta) to the verticals on the optical axis of the objective (4). The grey images obtained by the cameras are further processed as binary images, and logic operations are computed with a binary line grating in equal distance lengths of the fibre nap layer. The length measurement values are combined in series for the following evaluations, so that a quasi a real evaluation basis is given. The determined parameters are converted as vectors or sets for each image series at the evaluation algorithm, then treated with Fuzzy algorithm, so that effect quality can be classified.

Title: Control arrangement for motor vehicle IC engine
Inventor: HORI TOSHIO
IPC: F02D41/18
Filed: 1997-03-19
Abstract: The control arrangement includes an air-quantity determination unit (101,50) which determines a demanded in-take air quantity (Qs) corresponding to a nominal output power (Tr, N) of the engine. A fuel quantity determination unit (101,51) determines a demanded fuel quantity (Fs) which is conveyed to the engine. An in-take air-quantity limiting arrangement (102) outputs a predetermined limit (Qmax) as a total in-take air-quantity value (Qt) if the certain demanded in-take air-quantity oversteps the predetermined limit under a predetermined control condition. A correction arrangement (104) corrects the value of the demanded fuel quantity on the basis of the demanded in-take air-quantity (Qs) and the in-take air-quantity limit (Qmax) in such way, that the engine produces the nominal output power when the in-take air-quantity of the engine is limited.

Patent DE-19721976-A1 (DE)
Inventor: LAHRMANN ANDREAS DIPL ING DR
IPC: D06F34/22
Filed: 1997-05-26
Abstract: The invention relates to a method for detecting an unacceptably high degree of scale in an optical measuring section for measuring the turbidity of a lye in a household appliance which operates using calcareous water, such as a washing machine or a dishwasher. The household appliance has a circuit for evaluating the measuring signals from the measuring section (1) and a microprocessor (5) for transferring the measuring results to the sequential control of the appliance. This method is suitable for indicating an unacceptable degree of scale and for taking into account a deterioration of the measuring section due to scaling when determining the turbidity of the lye. Before or during first use of the appliance, a threshold value for acceptable deterioration of the measuring section by future scaling is memorized. During each operating cycle of the appliance, the deterioration of the measuring section during a cycle section which is carried out without turbid lye is measured and converted into a measured value, which is then compared to the threshold value. The microprocessor emits a control signal to the sequential control when the measured value reaches, or nearly reaches, the threshold value.
