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 optical sensor arrangement (10) comprises a light sensor (11) that is connected to a summation node (13) and is designed for generating a sensor current (S2), a current source (S2) connected to the summation node (13) and designed to provide a source current (S3), and an integrator (21) that is coupled to the summation node (13) and is designed for generating a first value (VP1) of an integrator signal (S6) by integrating during a first phase (P1) and for generating a second value (VP2) of the integrator signal (S6) by integrating during a second phase (P2). The optical sensor arrangement (10) comprises a sum and hold circuit (31) that is coupled to the integrator (21) and is designed to generate an analog output signal (S7) as a function of a difference of the first value (VP1) and the second value (VP2) of the integrator signal (S6).

Abstract: An optical device (306) includes an internal cavity and an emitter (102) disposed in the internal cavity (210). The emitter is operable to emit a first light wave (220). The optical device also includes a detector (104) disposed in the internal cavity. The detector is operable to detect a second light wave (225) that is based on the first light wave. The second light wave is susceptible to being coupled with an undesired light wave (235) that is based on the first light wave. The optical device further includes an interference filter (310) disposed on the detector. The interference filter has a filter property that causes the interference filter to attenuate the interfering light wave.

Abstract: An optical driver arrangement (10) comprises a comparator (11) and a pulse generator (15). The comparator (11) comprises a first input (12) for receiving a sensed output signal (S1) derived from a sensor signal (S2) generated by a light sensor (24), a second input (13) for receiving a reference signal (S3) and a comparator output (14) for providing a comparator signal (S4). The pulse generator (15) comprises a control input (16) coupled to the comparator output (14) and a generator output (22) for providing a driver signal (S5) to a light source (21). The driver signal (S4) comprises a series of at least one pulse and a parameter of the driver signal (S4) is controlled by the comparator signal (S4).
