Abstract: A lighting device for a motor vehicle, wherein the lighting device has a circuit board with a multiplicity of light-emitting diodes arranged thereon, a transparent optical layer, and a reflector element, wherein the reflector element is arranged between the circuit board and the optical layer, wherein the reflector element has multiple segments into which the reflector element is subdivided, wherein a segment is associated with each light-emitting diode so that light emitted by the light-emitting diodes can be reflected by the reflector element and can pass through the optical layer. Two light-emitting diodes are arranged in a segment. In addition, a lighting system and a motor vehicle are provided.

Abstract: A method for determining a switching state of a valve that is actuated by a coil, wherein the method includes: respectively ascertaining a current flowing through the coil and a voltage applied to the coil at several times which follow one another with a prespecified time interval, calculating an inductance variable of the coil based on the currents, the voltage and the time interval, and determining the switching state based on the inductance variable. Also disclosed is a solenoid valve assembly.

Abstract: Disclosed herein is a piezoresistive pressure sensor, including: a continuous piezoresistive foam layer; an electrode array layer, on one side of which the continuous piezoresistive foam layer is disposed; and an artificial leather layer as cover layer, which is disposed on the continuous piezoresistive foam layer; where the continuous piezoresistive foam layer is made by doping the foam with conductive materials. The piezoresistive pressure sensor can provide overall 2D-pressure mapping in a large area and has good flexibility and reliability to be combined with soft surfaces.
