Abstract: A method for detecting a first rotation angle of a first shaft of an engine is provided, whereby a first marking carrier with sensor-readable markings is provided, whereby the markings form a first marking pattern that has marking sections having at least one first and a second marking section. The first marking carrier is scanned by a first sensor and a first sensor signal is generated. The first sensor signal is modulated by the markings on the marking carrier. A correlation between a time course of the first sensor signal and a time signal is made by a computing unit. A first marking section is recovered from the first sensor signal by the computing unit, and then, a first exclusion criterion for excluding the first stored marking section is determined from the recovered first marking section. The first stored marking section is then excluded by the first exclusion criteria.

Abstract: 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.

Abstract: The invention relates to a signal display device for displaying signals, in particular on signal paths, in particular of a wiring harness, which may be connected to the signal outputs of an electronic apparatus (4) generating/receiving signals, or looped into the signal paths (SW) between a signal-generating electronic apparatus (5) and a signal-receiving electronic apparatus (6), and with which a signal to be displayed each time is measurable from a plurality, preferably all, of the signal paths (SW), and each measured signal is fed to an evaluation unit (7) that, for each measured signal, activates a multicolor display element (9) based on a value of the signal, such that one of several colors may be displayed using the multicolor display element (9).
