Abstract: A device for interior illumination for a vehicle includes an array formed by multiple light sources, with which an ambient illumination and a reading illumination can be generated inside the vehicle, an additional lamp unit with which exclusively an ambient illumination can be generated inside the vehicle, and a control unit for controlling the light sources and the additional lamp unit in three modes. The control unit is designed and configured in such a way that in the first mode the light sources are controlled in such a way that exclusively a reading illumination is generated inside the vehicle; in the second mode the light sources and the additional lamp unit are controlled in such a way that exclusively an ambient illumination is generated inside the vehicle; and in the third mode the control unit simultaneously activates the first and second modes for simultaneously generating an ambient illumination and a reading illumination.

Abstract: A device for controlling an interior lighting system of a vehicle to produce ambient lighting and/or reading lighting involves the interior lighting system having an array of a plurality of light sources. The device includes a control unit, by means of which the light sources of the array can be individually controlled in order to produce the ambient lighting and/or the reading lighting, and an input unit that can be connected to the control unit. The input unit has a touch-sensitive screen for inputting a current set of control information for the control unit. The control unit controls the light sources on the basis of the current set of control information. Furthermore, the input unit, on the basis of the current set of control information, displays associated ambient lighting and/or reading lighting for an illuminable region in the vehicle interior on the screen.

Abstract: A method for feedback of a temperature setting of an air-conditioning device involves adjusting a light color of at least one lighting element for the display of a set temperature. The adjusted light color corresponds to a temperature setting of an airflow zone in a motor vehicle.

Abstract: A system for identification and/or nowcasting of hail events with several measuring stations for detecting signals related to electromagnetic radiation in connection with lightning may comprise at least one time measuring unit for detecting the temporal course of the detected signals, and at least one analysis unit interconnected with the measuring stations and the time measuring unit. The analysis unit may comprise at least a first lightning signal analysis module for generation of a lightning signal analysis based on the detected signals, and a second lightning signal analysis module for identification of at least one lightning jump event based on the temporal course of the detected signals and the lightning signal analysis. The analysis unit may further comprise a nowcasting module for nowcasting concerning a hail event based on a lightning jump event. Furthermore, a method for identification and/or nowcasting of hail events is described.
