Abstract: A device for the detection of wetness in wheel arches of road vehicles includes at least one sensor arrangement including at least one capacitive moisture sensor with two electrodes, electrically insulated with respect to one another, and with at least one evaluation unit, the electrodes, electrically insulated with respect to one another, are arranged on a carrier element, that the electrodes, electrically insulated with respect to one another, are formed by two detection sections arranged parallel to one another, and that the detection sections, when used as intended, are aligned respectively in a rising manner in their longitudinal extent. The device also relates to a road vehicle for the detection of wetness, with at least one wheel arch, with which provision is made according to the invention that the wheel arch is delimited by a wheel-housing shell, at which a device according to the invention is arranged.

Abstract: The invention relates to a device for providing a fluid, in particular water, comprising a central supply device of warm fluid, preferably comprising a central heating system, for providing warm fluid, a supply device of cold fluid for supplying cold fluid, a local supply device of hot fluid, characterized in that a control device is arranged, which is designed to control the devices, in such a way that, below a warm fluid output quantity and/or below a temperature at at least one point of a warm-fluid supply line from the supply device of warm fluid to an outlet, the warm fluid is provided by admixing hot fluid, and above the predeterminable tapped warm-fluid quantity and/or temperature at at least one point of a warm-fluid supply line, the warm fluid is provided by the central supply device of warm fluid.
