Abstract: A simple optical projection device with a high luminous efficacy has a point light source, a projection screen, a mask that is arranged in the light path upstream of the projection screen and is light-transmissive in some areas, and a light focusing optical lens arranged between the point light source and the mask. The optical lens is selected such that the prolongations of the emerging beams of the optical lens on the side thereof facing the point light source intersect in a virtual perspective center which is more remote from the lens than the point light source.

Abstract: In a method of determining a position of a touch on a capacitive sensor field having a grid of a plurality of discrete electrodes (12), contacted electrodes are determined by measuring a capacitance value for each of the electrodes and by checking for each of the electrodes for the measured capacitance value whether this value is above a predefined threshold value. A rough touch position (Bg) is calculated by weighting the electrode position with the measured capacitance value. A touch diameter (14) is calculated from the measured capacitance values, and a final touch position (Be) is calculated from the rough touch position (Bg) and the calculated touch diameter (14) using a value table in which correction values that were determined empirically or by means of simulation are stored for possible rough touch positions (Bg) and given touch diameters (14).

Abstract: A capacitive rotary encoder has a stator and a rotor as well as stator electrodes firmly arranged at the stator on an encoding path coaxial to the rotor axis, and coupling electrodes arranged at the rotor. The coupling electrodes are guided over the stator electrodes at a small axial distance from the encoding path by rotation of the rotor, wherein they each cover stator electrodes adjacent in the peripheral direction and connect the latter capacitively to each other. Interrogation electronics detects for each of the stator electrodes a capacitive coupling with an adjacent stator electrode caused by a coupling electrode of the rotor. This permits the reliable detection of the angular position of the rotor both statically and dynamically.
