A test bench () is described and shown for testing a distance sensor () operating with electromagnetic waves, wherein the distance sensor () to be tested comprises at least one sensor radiating element () for radiating a transmission signal () and a sensor receiving element () for receiving a reflection signal, with a receptacle () for holding the distance sensor () to be tested, with an at least partially movable connecting member () in the radiation area of a distance sensor () held in the receptacle (), with at least one test bench receiving element () held in the connecting member () for receiving a transmission signal () radiated by the sensor radiating element (), and with at least one test bench radiating element () held in the connecting member () for radiating a test bench transmitting signal () as a simulated reflection signal. A reliable environment simulation, in particular for the testing of multiple input-multiple output distance sensors () is achieved in that at least one test bench receiving element () and one test bench radiating element () are arranged together in a movable part () of the connecting member ().

A computer-implemented method for calculation and output of control pulses by a control unit having a first computing unit and a second computing unit, wherein the control pulses are output by the control unit to an internal combustion engine. The calculation of the control pulses is optimized in that the first computing unit calculates a control pulse pattern with triggering information for multiple future control pulses at a first sampling rate using prior state data of the engine, and transmits the calculated control pulse pattern to the second computing unit, that the second computing unit at a second sampling rate that is greater than the first sampling rate of the first computing unit corrects the triggering information of the control pulses that are currently to be output using current state data of the engine, and that control pulses are output to the engine based on the corrected triggering information.

The invention relates to a signal display device for displaying signals on signal paths of a wiring harness, for example, which may be connected to the signal outputs of an electronic apparatus generating/receiving signals, or looped into the signal paths between a signal-generating electronic apparatus and a signal-receiving electronic apparatus. A signal to be displayed each time is measurable from a plurality, preferably all, of the signal paths, and each measured signal is fed to an evaluation unit that, for each measured signal, activates a multicolor display element based on a value of the signal, such that one of several colors may be displayed using the multicolor display element.
