Abstract: A device is provided including a headlamp including imaging elements for the targeted generation of pixels of a light distribution, and which is set up so that individual imaging elements are actuated separately via pulse width modulation to specify the luminous flux generated by the imaging element through the ratio of the on-phases and the off-phases of the pulse width modulation. A camera features an image sensor with a plurality of sensor elements read out consecutively to detect image information from different solid angle ranges illuminated by the headlamp. A control unit actuates the headlamp and the camera, and regulates temporal overlap between on-phases of the actuation of an imaging element and reading out of at least one sensor element of the camera which is hit by light generated by the imaging element, depending on the size of luminous flux generated by the imaging element.

Abstract: An apparatus for identifying a weather condition in surroundings of a vehicle, which includes an illuminating unit for illuminating the surroundings, a control unit for controlling the illuminating unit, an image capturing unit for capturing image information of the surroundings, an evaluation unit for evaluating the image information, image data provided by the image capturing unit being compared with predefined reference image data, each characterizing different weather conditions, and a weather condition signal being generated, depending on a match of the comparison, the control unit including a pulse modulation device, with the aid of which the illuminating unit is controlled in such a way that the illuminating unit emits pulsed light signals

Abstract: A lighting device for a motor vehicle, in particular a headlamp, comprising at least two, preferably three, light sources, from which light emanates during the operation of the lighting device, the light of each of the light sources differing from that of the other light sources with regard to its wavelength spectrum, comprising modulator, which bring about a modulation of the light emanating from the light sources during the operation of the lighting device, so that information is transmitted by the light, the lighting device having a mixer for mixing the light emanating from the individual light sources, so that white light emerges from the lighting device during the operation of the lighting device.

Abstract: A method for detecting misadjustments of a headlamp of a vehicle and to a device for this purpose. It is provided that the vehicle is provided with a detector with which at least one light signal of another road user is detected, and wherein the vehicle is equipped with a control unit with which light signal information of the detector is captured and by means of which adjustment information for correcting the misadjustment of the headlamp is output as a function of the captured light signal information.

Abstract: A laser light source unit for vehicles, with a resonator containing a first end mirror and a second end mirror, between which an active laser medium is arranged, and with a pump device for generating pump radiation, which can be introduced into the resonator via the first end mirror, wherein a rotatable birefringent medium is arranged in the resonator such that, according to a rotation of the birefringent medium, preferred radiation of different wavelengths is stimulated in the active laser medium.

Abstract: Communications system for motor vehicles are provided, that comprise a plurality of transmission devices and a plurality of receiver devices where the transmission devices, individually or together, feature several light sources that are able to emit at least light with a first wavelength spectrum and light with a second wavelength spectrum. The transmission devices feature means of modulation that can effect modulation of the light such that information can be transmitted via the light. Receiver devices can capture the emitted light and extract the information from the captured light. The communications system is designed in such a way that the light with the first wavelength spectrum is used for the transmission of information in a first category and the light with the second wavelength spectrum is used for the transmission of information in a second category.
