Abstract: A capacitive measuring system includes capacitive sensors and an evaluation circuit having a multiplexer, a synchronous rectifier, a sinusoidal signal generator, and a reference voltage divider. The capacitive sensors are acted on by a mono-frequency voltage signal generated by the sinusoidal signal generator, output signals of the capacitive sensors are transmitted in alternation to the synchronous rectifier via the multiplexer, and signal amplification of output signals of the synchronous rectifier are calibrated as a function of an activatable reference impedance. The synchronous rectifier is formed by a MOS semiconductor switch. A source-drain section of the MOS semiconductor switch forms a shunt that is controlled by the mono-frequency voltage signal. A channel of the multiplexer is provided for transmitting a calibration signal, generated by the reference voltage divider, to the synchronous rectifier alternately with the output signals of the capacitive sensors.

Abstract: A blockage detection system and methods for use in a radar sensor such as a side object detection (SOD) sensor in an automotive radar system are described. The blockage detection system and method operate in systems including two or more radar sensors having overlapping field-of-views (FOVs). The blockage detection system includes a storage in a first radar sensor having stored therein a tracked object list including detections/tracks for one or more targets made by a second radar sensor and a processor for adjusting an overlap zone associated with the first radar sensor based upon an estimated mounting angle of the first radar sensor.

Abstract: The invention concerns itself with the automatic processing of metal sheets. These are placed onto pallets (6) in form of stacks (7) and are fed to a pallet storage (4) in form of a high multi-tier shelf coordinated to each production machine (1). Between the pallet storage (4) and the production machine is provided a transport device (9) movable vertically along the pallet storage, which accepts a pallet (6) with a sheet metal stack (7) or delivers an empty pallet (6). The transport device (9) contains a single-sheet feeder (11), for example in the shape of suction heads (20) which lift off the topmost sheet, place it on a sheet support table (23) and from there feed it to the production machine. So as to facilitate the disengagements of the sheets from one another, magnets (18) are so arranged that under their influence they spread the forward positions of the sheets from one another.
