Abstract: A planar cladding element(4) for surfaces of planar building parts, in particular in operating rooms, rooms prone to moisture or on building surfaces that are accessible for moisture, which cladding element is equipped with a transmission device (1) for electrical energy and/or electrical signals, which transmission device includes a supply module (5) for electrical energy and/or electrical signals and a discharge module (6) for electrical current and/or electrical signals, which modules can be releasably connected to each other in such a way that the electrical energy and/or the electrical signals can be transmitted, characterized in that in the transmission device (4) specified at the beginning the supply module (5) is arranged behind the cladding element (4) without an interruption, while the discharge module (6) is arranged in front of the cladding element (4) without an interruption, and in that both modules (5, 6) include elements for the inductive transmission of electrical energy and/or electrical sig

Abstract: At least partially transparent sheet-like covering element (2) provided with a detection system for the presence and/or characterization of an object or a material and associated further embodiments of the invention. The covering element is characterized in that it is fitted in front of or to the wall substrate of a wall of a building, substantially over the entire surface thereof, and the detection system (operating element, “touch panel”) operates according to the “projected capacitive touchscreen” principle and is provided or implemented such that it rests against the transparent sheet-like covering element on the rear side (wall side), as seen by the observer, and is provided or implemented in front of or in the wall substrate having the covering element. Uses are, for example, the control of devices and functions in operating theatres or other rooms.
