Abstract: An electromagnetic valve has a magnetic coil and a movable element coupled to a valve element. The magnetic coil, when excited, conveys the movable element in one direction to move the valve element from its initial position into its active position. A control circuit for the electromagnetic valve has a current source for optionally supplying current to the magnetic coil and a measuring device for measuring a voltage level of the magnetic coil and/or a current level through the magnetic coil. A monitoring unit which is connected to the measuring device establishes a switching state of the electromagnetic valve corresponding to the position of its valve element based on the intended current supply state of the current source and the current and/or voltage characteristic measured by the measuring device and, if appropriate, determines a fault state of the current supply and/or the electromagnetic valve.

Abstract: A sensor device which can be used, for example, for an operating device, for example of an electronic household appliance, in order to detect a movement and/or position of a first component relative to a second component. The first component can be moved about a or in the direction of an axis of movement along a movement path, includes a sensor electrode arrangement on the second component and a signal element on the first component opposite and at a distance to the sensor electrode arrangement. The signal element has electrically conductive sections and electrically non-conductive sections, as well as a sensor control system for inputting sensor signals and receiving measurement signals at/from the sensor electrode arrangement and an evaluation unit for determining a movement and/or position of the first component relative to the second component based on the measurement signals of the sensor control system.
