    Abstract: An optical display and control element comprises an at least partially transparent display screen, at least one light source for illuminating a rear side of the display screen, and at least one light sensor for detecting a temporal signal of the light scattered on the display screen. The light source is able to produce a time-variable light pattern while illuminating the rear side of the display screen. A control and processing unit is able to evaluate the temporal signal, detected by the light sensor, in combination with the time-variable light pattern and to determine a position of at least one object located on the display screen from this evaluation. The invention further relates to a method of optically determining the position of an object which is located on an at least partially transparent display screen of an optical display and control element.

    Abstract: An optical sensor device has a sensor unit which includes a light emitter (24), a light receiver (26), and a lens plate (12) that is used for coupling a pencil of rays, radiated by the light emitter (24), into and out of the pane and directing it onto the light receiver (26). The lens plate (12) includes a combined Fresnel structure (16a, 16b) having a Fresnel lens structure (18a, 18b) and a Fresnel reflector structure (20a, 20b) on a first surface (12a) facing the light emitter (24) and the light receiver (26), and a Fresnel reflector structure (22a, 22b) on an opposite, second surface (12b) facing the pane. This configuration is especially suitable for use as a rain sensor. Without the light emitter the sensor device is suitable to be used as a light sensor.

    Abstract: The method operates with successive, continuously repeated measuring cycles. In a first cycle section, a measuring capacitor is charged up to a first threshold value by the current flowing in a light receiver of a first optical measuring section. In a subsequent, second cycle section the measuring capacitor is discharged to a second threshold value by the current flowing in a light receiver of a second optical measuring section. The light transmitters of the optical measuring sections are regulated over several measuring cycles to predetermined rated values for the charging time and the discharging time. A wetting of the pane is concluded from the momentary deviations between the rated values and the actually measured values of the charging times and discharging times. The available modulation range is adapted dynamically to the prevailing conditions by the systematic control of the intensity of the light transmitters in the two optical measuring sections. In addition, the upper limit of the modulation range is extended to higher values of the ambient light.

    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: 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.
