Abstract: A method for the mounting of an add-on part (3) on a workpiece (1), in particular on a vehicle body, the intention being for the add-on part (3) to be aligned on the workpiece (1) in a precisely positioned manner in relation to a reference region (12, 13). Use is made of a robot-guided mounting tool (5) which is connected fixedly to a sensor system (20). In order to achieve the precisely positioned alignment of the add-on part (3), an iterative control operation is run through, in the course of which first of all an (actual) measured value of the sensor system (20) is produced and is compared with a (desired) measured value produced within the context of a setting-up phase.

Abstract: An apparatus for recognizing road conditions, for use especially in a motor vehicle, includes an infrared transmitter-receiver system. Devices are provided which make it possible to separate signal fractions into different infrared wavelength ranges. This allows for the reliable evaluation of the conditions of the road section being monitored, using a simple and economical device. The infrared devices may be combined with a microwave device.

Abstract: To synchronize a decoder at the receiving end, particularly an MPEG audio decoder, with the corresponding coder operating at the transmitting end, it is proposed to supply the data decoded by the decoder to a FIFO memory, the output clock rate at which the data are read out or output from the FIFO memory, being adjusted as a function of the loading level of the FIFO memory.
