Abstract: A system comprises a set of power conversion components powered by a power line system, and a time domain reflectometry apparatus coupled to the power line system. The time domain reflectometry apparatus is configured to acquire a reflection signal that results from reflection of an incident signal injected on the power line system, compute a difference signal based on the reflection signal and a baseline signal, and detect a fault in the set of power conversion components based on the difference signal and a fault pattern.

Abstract: The invention relates to a device, comprising a camera unit, which is used to record images of the exterior area of a motor vehicle, and a cover element, which can be moved from a closed position to an open position by means of a drive, wherein the camera unit is behind the cover element and inaccessible from outside in the closed position of the cover element and images can be recorded in the open position of the cover element. For this purpose, the cover element has an outer surface facing away from the camera unit, and the drive interacts with a mechanism in such a way that the outer surface is always in the exterior area of the motor vehicle in each position of the cover element during the movement of the cover element between the closed position and the open position.
