Abstract: A temperature-independent rotation damper 100 is presented. A housing 108 and a piston 102, between which a viscous liquid is located in annular gaps 118, 120, rotate one around the other. When the temperature falls, the damping by the viscous liquid increases. This effect is countered by reducing the effective area which constitutes the braking action, or by enlarging the volume in the annular gaps 118, 120. As the drive, a material having a positive expansion coefficient is used, which material drives a piston 132. In this way, the damping of the rotation damper 100 is broadly practically independent of the temperature.

Abstract: The present disclosure relates to a method for monitoring an on-board electrical system of a vehicle having at least one distributor and a load that are connected together via a cable. In one implementation, the method includes reading in a sequence of data for a number of parameters representing information about operation of the vehicle by a driver and/or about a state of the vehicle and/or a state of the driver and/or a driving environment; classifying the data as a normal value or an error value; and evaluating the data classified as an error value or a normal value. The normal values may lie within a state space separated from the error values by a discrimination limit. Evaluating the data classified as an error value may include determining if the data classified as an error value fulfils a criterion, and evaluating the data classified as a normal value may include statistically evaluating to determine a stochastic parameter and determining if the stochastic parameter exceeds a threshold value.

Abstract: The present disclosure relates to a screw connection comprising a support component, an additional component and a screw to fasten the support component to the additional component. The support component has a tube made of thermoplastic foam to accommodate the screw in a friction and positive fit. The screw has a blunt-edged thread, enabling the screw to compress the foam in the tube as it is driven in. The ratio of the inner diameter of the tube to the diameter of the screw depends on the degree of foaming of the tube and decreases as the degree of foaming increases. In comparison to conventional screws, the threads of the screw of the present disclosure penetrate less deeply into the foam or they displace it, preventing damage to the tube while enabling a tight fit.
