Abstract: To allow an easily producible lighting device that manages with few components and enables an efficient, desired light distribution in an interior space, the provided method and device includes a light guide with a longitudinal transport section and at least one transverse transport section. The longitudinal transport section has at least one light entry surface, arranged transversely with respect to the longitudinal extension of the longitudinal transport section, for coupling light into the longitudinal transport section, and a light exit section along the longitudinal extension. The transverse transport section has a flat design, and is connected to the longitudinal transport section at at least one first narrow side. The transverse transport section also has secondary deflection elements at which the coupled-in light is deflected in such a way that the light exits at the opposite broad sides.

Abstract: A method for producing a lighting device and a lighting device, comprising a flat light guide extending in a z-direction, wherein the light guide has a thickness, a back side, a front side and circumferential narrow sides, and scattering particles are arranged in its volume. A reflector is arranged at the back of the light guide and at least one light source is optically connected to the light guide for coupling light. Furthermore, the lighting device has a surface coating. In order to provide homogeneous illumination of the interior and a compact lighting device, the surface coating has a light transmission starting from the at least one light source in the z-direction, which increases to the extent that the curve of the light intensity of the at least one light source decreases and the light guide is formed by cohesive back-injection of a carrier foil with the surface coating.

Abstract: An electric motor, in particular for an electromechanical brake device of a vehicle, includes a stator and a multi-pole rotor with an odd number of rotor poles. Recesses are defined in the central region of the rotor poles, drive assembly, and electromechanical brake device for a vehicle.

Abstract: A process for transfer of signals is provided between a first control unit and at least a second control unit, wherein the first control unit, based on the input data, selects at least a first signal that is to be transferred, and the first control unit has at least one signal output, at which a first PWM signal can be emitted, wherein a first PWM signal is encoded and assigned to each selected at least one first signal, and wherein the second control device has one first signal input, which receives the first PWM signal and the second control device evaluates the first PWM signal received and detects the first signal and, based on the first signal transferred, creates a subsequent control instruction. A related device is also disclosed.

Abstract: A device for creating dynamic light effects includes an optical fiber with at least two light sources (, which feed light into the optical fiber, wherein the light from the light sources is mixed in the optical fiber in such a manner that a variation of color is identifiable in the optical fiber, and wherein the light sources can be controlled in such a manner that a dynamically changing color distribution is obtained in the optical fiber. A related process is also disclosed.

Abstract: The present invention relates to a brake booster device for a vehicle brake system comprising a force input element, a control valve arrangement actuable via the force input element, a chamber arrangement disposed in a housing and comprising a vacuum chamber and a working chamber, which is separated from the vacuum chamber by a movable wall and connectable selectively to a vacuum source or the atmosphere, and a force output element, wherein the movable wall is biased into a normal position by a resetting spring accommodated at least partially in the housing and wherein the housing is penetrated by at least one fastening bolt.
