摘要： From a prescribed starting value, the emitting power of an obstacle detection beam increases or decreases according to a prescribed function at a prescribed rate. The received signal reflected from an obstacle is compared to a prescribed threshold. Once the received reflected power rises or falls to the threshold, the emitting power is not further increased or decreased respectively, but is maintained constant. Thereby, consumed and dissipated power is reduced, unnecessary excessive power use is avoided, and the detection range of the obstacle detection beam is adapted to the prevailing situation.

摘要： The invention relates to analog circuits which are constructed as fed-back amplifier networks. The networking is implemented such that the output values of the individual amplifier elements are fed back to the input values of the respective adjacent amplifier elements. The degree of feedback can be statically and dynamically adjusted according to the specific application. Two-dimensional networks with such an architecture can be used, for example, in image processing for the interference reduction under real-time conditions.

摘要： The present invention relates to an electromagnetic mixing system for receiving and processing modulated electromagnetic signals, with a signal detector made from a semiconductor material for receiving and converting electromagnetic radiation into an electric measured value and with at least one modulation input modulating the reception of the signal detector, and also with at least two accumulation electrodes which are connected to output electronics at the output of which a mixture of the received signal and at least one modulation signal applied at the modulation input is effectively provided as electric signal. The present invention also relates to a method for operating such an electromagnetic mixing system, the electromagnetic signals striking the signal detector producing charge carriers which, depending on the at least one modulation signal, are conducted at least partially alternately to the at least two different readout electrodes. In order to create a system and a method which also delivers correct mixer results in the case of geometric or electric asymmetries of the PMD elements, i.e. measurement signals based exclusively on the coherent radiation, it is proposed according to the invention that apparatuses for modifying parameters of the at least one modulation signal are provided such that by modifying these parameters the output signal is different from a zero signal only if the modulations of the received electromagnetic radiation signal and the at least one modulation signal are correlated with each other. As regards the method, it is proposed that the signals derived from the accumulation electrodes and entered [by] the output electronics are varied such that the output signal assumes a value different from the zero signal only if the at least one modulation signal and the modulated electromagnetic reception signal are correlated with each other.

摘要： An arrangement and method for processing a signal field of sensor signals which originate from the individual sensor elements, for example photodetectors, of a plurality of sensor elements which are regularly spaced in an area and which are each surrounded by six adjacent sensor elements while forming a hexagonal structure. A differential amplifier compares a quantity representing the potential difference and a reference quantity forms a switching quantity (I.sub.Mo) on the output side. A switching comparator, on the input side, receives the switching quantity and, if this switching quantity exceeds the preselectable switching threshold, on the output side emits a switching pulse which causes the "off" switching condition. Four signal outputs 1, 2, 3, 4 as well as four signal inputs (I.sub.M1 I.sub.M2, I.sub.M3, I.sub.M4) are each connected with a signal input and a signal output of one of the four analog circuits assigned to the four next adjacent switchable resistors, one signal respectively being supplied to the four signal outputs which represents the switching quantity. A switching stage for forming the reference quantity takes into account the signals present at the four signal inputs.
