Abstract: The present invention relates to an optoelectronic sensor for 5 demodulating a modulated photon flux (50), and to a measuring device, in particular for 3D distance measurement, having at least one optoelectronic sensor of this type. The optoelectronic sensor has at least two collecting zones 10 introduced in a semiconductor region (10), which collecting zones are for example diffused into the semiconductor region and doped inversely with respect to the semiconductor region (10). The collecting zones serve for collecting and tapping off minority carriers generated upon penetration of a modulated photon flux (50). Furthermore, at least two control zones are introduced in the semiconductor region (10), which control zones generate a drift field in a manner dependent on a control voltage that can be applied to the control zones, the control zones being of the same doping type as the semiconductor region (10).

Abstract: The invention relates an electronic switch for switching on and off high AC voltage between two connecting terminals. The switch includes two series-connected MOS floating gate transistors (20, 30; 20′, 30′), that can block and establish the transmission path between the applied high AC voltage connecting terminals. A charge storage device (24, 27, 34, 37; 24′, 34′, 60) stores charges and is connected to each gate of the MOS transistors. Each charge storage device (24, 27, 34, 37; 24′, 34′, 60) is assigned a charge feeding device (40, 50; 50) for applying a predetermined quantity of charge to the charge storage device (24, 34; 24′, 34′), which corresponds to a first switching state, and for removing a predetermined quantity of charge from the charge storage device, which corresponds to a second switching state. In this way, very low energy sensor outputs control high power AC voltage applied to the connecting terminals.

Abstract: The invention is based on the object of making available a control and data transmission system which uses simple components to permit current-modulated data transmission via a serial bus, and whose components can be used in a flexible way. For this purpose, the control and data transmission system (50) has a controllable bus terminating device (30) for impressing a predetermined working current into the bus (42, 44). Each subscriber (1, 2) has a D.C.-coupled transmitter (60) for generating and emitting control signals and data signals which modulate the working current, and a D.C.-coupled receiver (20) for sensing and evaluating the working current which is modulated by the control signals and data signals.

Abstract: Process and circuit layout for using an independent capacitor for the momentary retention of an output voltage when an input voltage is lost. To facilitate a reduction in capacitance in independent circuits of this type at a constant amount of charge, the input voltage is transformed by a DC/DC up converter to a higher capacitor voltage, which is stored in the independent capacitor and the capacitor voltage is transformed by a DC/DC down converter to the output voltage for the load element, which is less than the capacitor voltage. As the DC/DC down converter can utilize capacitor voltages until the output voltage is reached, the residual voltage remaining in the independent capacitor (C) is no longer used. The independent time interval is correspondingly short. According to the invention, the capacitor is disconnected from the output of the DC/DC up-converter and connected to its input when the input voltage is less than a reference voltage.
