Abstract: An optical proximity sensor arrangement comprises a first sensor unit with a first emitter and a first detector and a second sensor unit with a second emitter and/or a second detector. The first detector is configured to detect light being emitted by the first emitter and, if applicable, by the second emitter, and being at least partially reflected. If applicable, the second detector is configured to detect light being emitted by the first emitter and being at least partially reflected. A distance between the first emitter and the first detector is, if applicable, less than a distance between the first detector and the second emitter and, if applicable, less than a distance between the first emitter and the second detector.

Abstract: A control system for a gesture sensing arrangement with at least one sensor operates the sensor in a proximity mode. The control system receives data sets generated by the sensor and based on these data sets determines whether an object is present in a vicinity of the sensor. When an object is detected in the vicinity the control system operates the sensor in a gesture mode. Based on further data generated by the sensor the control system determines an end of a gesture, and operates the sensor in the proximity mode.

Abstract: An embodiment of a method for compensating variations in an attenuation of light of an optical filter of a light sensor system comprises illuminating a clear sensor and a color sensor of the light sensor system with a test light having a test spectrum. Therein the color sensor comprises the optical filter and is designed to predominantly sense light with a wavelength within a pass band of the filter; and the test spectrum has components outside the pass band. A clear test signal generated by the clear sensor and a color test signal generated by the color sensor are received in particular in response to the illumination with the test light. Then a first transmission value T is determined based on the clear test signal and on the color test signal. Finally, a compensation factor Kr, Kg, Kb is calculated to compensate the variations in the attenuation of light based on the first transmission value T and a nominal transmission value Tn of the filter.
