Abstract: A display device for a motor vehicle is used to display a number relating to the motor vehicle or a symbol relating to the motor vehicle. The display device has a layer made of a light-emitting polymer for emitting light of a first colour, a transparent carrier layer and a mask which is arranged on the transparent carrier layer and provided with an opening in the form of the number or signal, or the display device has a layer made of a first light-emitting polymer for emitting light of a first colour and a second layer, which is arranged close to the first layer and which is made of a second light-emitting polymer for emitting light of a second colour.

Abstract: A rotary knob is for operating a motor vehicle by rotation of the rotary knob, the rotary knob having an at least partially transparent display layer which rotates along in response to an angular movement of the rotary knob, and a controllable light source for displaying changeable information on the display layer.

Abstract: A display device for a vehicle includes a transparent window with a light emission layer intended to separate the interior of the vehicle for emitting visible light when light is beamed onto the light emission layer, a light source for beaming light onto the window, a reflector mounted in a light path between the light source and the window to reflect the light generated by the light source and an adjustable image generator located between the light source and the reflector.

Abstract: A 3D navigation system for motor vehicles includes a set-up combining a first motor vehicle and an environment scanner to generate a three-dimensional image of an environment around the first motor vehicle or at least a part of the environment around the first motor vehicle as well as at least a second motor vehicle and a communications connection between the first motor vehicle and the second motor vehicle for transmitting the three-dimensional image of the environment around the first motor vehicle or at last a part of the environment around the first motor vehicle to the second motor vehicle.

Abstract: A display arrangement for a vehicle has, in particular, a multipurpose instrument or is configured as a multipurpose instrument. The display arrangement includes a first display device to display information concerning operation of the vehicle, a glass with adjustable transparency arranged in front of the first display device, with reference to the viewing direction of the display arrangement, and a second display device to display information concerning operation of the vehicle or additional information concerning operation of the vehicle.

Abstract: A seat for a vehicle comprises a seat surface and a monitor arranged on a side of the seat facing away from the seat surface for display of freely variable pictures or symbols, in which the monitor contains an emission layer, containing a light-emitting polymer, and a transparent carrier layer, made of a flexible material.

Abstract: The invention concerns a device for determination of the surface condition of a roadway, in which the device includes a light-sensitive sensor to measure a light signal reflected from the surface of the roadway and an analyzer to determine the surface condition of the roadway as a function of the power of the light signal at a first wavelength in the infrared range, at a second wavelength in the infrared range and at at least a third wavelength in the infrared range.

Abstract: A motor vehicle and an indicating apparatus for a motor vehicle, includes a display for optical depiction of information concerning the motor vehicle by the emission of light, and having a decorative layer positioned on the display.
