Abstract: The invention relates to a strain-sensitive resistor, comprising a resistance layer arranged on a support element and an electromechanical transducer produced with this resistor. An increase in the electrical measured signal picked off across the resistor is achieved in a simple way by the support element (1) having a recess (7) on its surface (9) which, when the support element (1) is subjected to mechanical stress in at least one area of the surface (9) of the support element (1) in which the resistance layer (4) is positioned, produces a ratio between the two main strain directions (L, T) of the resistance layer (4) which differs in magnitude.

Abstract: A passive magnetic position sensor is constructed of an electrically non-conductive, non-magnetic substrate on which a resistance layer and a soft-magnetic, electrically conductive bending-beam structure are arranged. The resistance layer and bending-beam structure are arranged at a constant distance apart partially overlapping each other. The distance apart is selected so that, under the action of a magnet device conducted along the overlapping region of the bending-beam structure and resistance layer, contact is produced between resistance layer and soft-magnetic bending-beam structure. In order to provide a position sensor which permits a precise tapping of voltage, the electrically conductively developed resistance layer has along its longitudinal direction a meander-like structure adjoined by taps which have contact surfaces on the regions opposite the soft-magnetic bending-beam structure.

Abstract: In a system having an electronic controller for internal combustion engines, particularly injection engines in which the controller is functionally connected to a plurality of sensors and at least one actuator, the controller is part of an assembly which furthermore comprises a throttle-valve arrangement, an air-mass sensor and a throttle-valve position sensor. In systems with central injection, the injection valve can also be arranged within the assembly. By the compact structural unit thus obtained, cable connections are reduced to a minimum, so that, in their turn, reliability is increased and expense is saved. Furthermore, the arrangement facilitates maintenance and repair.
