Abstract: A signal is processed for recognize an irregularity in the signal. First, an orthogonal imaginary signal corresponding to the signal to be processed is formed. This is followed by a transformation step, which is then followed by a differentiation step. The signal thus processed shows the irregularity particularly clearly, so that the irregularity can be isolated, selected and detected. Preferred fields of application for the present method and corresponding devices are in the medical field, information technology, and signal treatment in network engineering, in particular low, medium, and high voltage engineering.

Abstract: The method provides a better incorporation of a defined safety interval from obstacles in the route planning of a self-propelled mobile unit. By contrast to methods that were hitherto standard, a shell with equidistant spacing from a housing of the self-propelled mobile unit is not placed around the mobile unit; rather, the safety interval is calculated via the route at a drive wheel of the self-propelled mobile unit. That is, the kinematics of the self-propelled mobile unit are first used in the calculation of the safety interval from obstacles. The advantage is that better maneuverability is achieved between obstacles located close to one another.

Abstract: For testing structural ceramic parts under overload conditions, a previously calculated temperature distribution is generated on the part by thermal radiation, this temperature distribution inducing the desired test stress or overload. The temperature distribution is measured with topically and temporally resolving temperature sensors, is compared to a desired or calculated temperature distribution, and is regulated by varying the duration and/or location of the radiation influence until the desired temperature distribution has been produced.
