Abstract:
An operator element having freely programmable symbols, which includes a keycap, a display unit arranged at a distance and behind the keycap in a housing of the operator element, whereby the display unit interacts with a light-guiding element so that symbols are projected onto the keycap, and a diffusion layer attached to an inner face or outer face of a top part of the keycap. Further, the display unit is self-illuminating or is a transmissive, a reflecting, or is a self-illuminating display unit that is transilluminated and/or illuminated directly by a light source or via an optical system. In addition, the keycap is made of a black-transparent material.
Abstract:
The invention relates to a cap (1) for a display and/or control element, comprising a cap member (2) for covering a light source and/or actuating a switch of an associated control element. A luminous area or projection area is embodied in the cap member (2) in such a way that a symbol (5) represented on or through the luminous area or projection area becomes visible for an operator of the control element by irradiating the symbol (5) by means of a light source located on the switch side. The cap (1) is characterized in that the luminous area or projection area encompasses a light-permeable metal coating (4) which is preferably applied using a PVD process. The invention further relates to an associated production method, a display or control element comprising said cap, and a use.
Abstract:
A solar sensor is provided that has microspheres on an interior face of a protective cap or of another radiation-transparent area above a transducer of the sensor. The microspheres scatter the light but at the same time have a much lower damping effect. Preferably, the microspheres are glued to or sealed into the interior face.
Abstract:
Sensor unit (1) for a motor vehicle for detecting ambient conditions, comprising at least two sensor modules, wherein a first sensor module (2) has a rain (6) and/or condensation sensor (7), and a second sensor module (3) has at least a light (13, 14) and/or solar sensor (11, 12).
Abstract:
An operating element with freely programmable symbols is provided for a motor vehicle, having a transparent keycap movably accommodated in a housing, a light source arranged in the operating element, a means for parallelizing the light emitted by the light source, and a programmable display element that can be transilluminated by the parallelized light, wherein the display element is arranged behind the keycap in such a manner that the symbols displayed by the display element are projected onto the keycap, wherein the means for parallelizing the light is designed as a concave mirror, and in that the light source is located between the display means and the concave mirror.
Abstract:
The invention concerns an operating element, in particular a pushbutton, for a motor vehicle, having at least of a touch-sensitive pushbutton operating on a capacitive basis and a housing, wherein the pushbutton is movably mounted in the housing, wherein a capacitor that forms the capacitance is composed of a metallic area applied to an inner or outer side of a surface facing the user, and the metallic area forms an electrode of the capacitor that is electrically contacted in the housing.
Abstract:
An ambient light sensor system is provided for sensing ambient light and light in the area in front of a motor vehicle, wherein the ambient light sensor system includes a light guide element arranged behind a transparent surface of the motor vehicle and at least two sensors arranged on the light guide element.
