Abstract: A device, method, computer program and computer readable medium allowing for vehicle to vehicle and vehicle to infrastructure communication. An ignition key radio technology may used in addition to WLAN-based communication in a vehicle in order to communicate with other vehicles or infrastructure. The ignition key radio technology is used to send only selected data which have been altered significantly. The remaining data are not sent or kept for the WLAN communication.

Abstract: A solar installation includes at least one solar module. The at least one solar module includes a cover plate and a housing box. The housing box includes housing walls, a frame construction including a substantially L-shaped support profile, the support profile including a transverse leg disposed edge-parallel on a bottom side of the cover plate with a seal interposed therebetween and a longitudinal leg connected to the housing wall. A detent device has at least one upper detent element and one lower detent element for fixing the cover plate on the housing box. A spring-loaded mounting includes at least two spring elements for mounting the cover plate on the housing walls, via the at least two spring elements. The at least two spring elements have a predetermined vertical stroke and are configured to generate a restoring force.

Abstract: A vehicle key for storing a vehicle identifier with a communication unit and a memory unit, wherein the communication unit is designed to receive the vehicle identifier from a transmitter, and wherein the memory unit is designed to store the received vehicle identifier.

Abstract: An emergency call unit for a vehicle includes not only a detection unit, a position-finding unit and a control unit, but also a transmission unit for the repeated transmission of a locating signal to a rescue worker. In this context, the locating signal may correspond to the position of the vehicle, and the transmission of the locating signal is initiated by a trigger event. By way of example, the trigger event is a request from a rescue worker or is the detection of an accident.

Abstract: A fixing device for fixing a photovoltaic module on a sloping roof having a roof structure and a roof covering with individual roof covering elements includes a roof-side connecting piece disposable beneath the roof covering and a module-side connecting piece disposable on an edge of the photovoltaic module. A flexible retaining element interconnects the roof-side connecting piece and the module-side connecting piece. The flexible retaining element is loadable by pulling and adapted to be guided through the roof covering without altering a position or shape of the individual roof covering elements.

Abstract: A photovoltaic unit includes a matrix having a plurality of frameless rectangular solar modules, and at least one module rail disposed on an underside of each solar module. Each of the at least one module rail is coupled to a substrate rail, which is releasably connected to a substrate. Each of the at least one module rail and the at least one substrate rail has a guide rail running parallel to an edge of the respective solar module on at least a longitudinal side of the respective rail facing towards an edge region of the solar module. The guide rails on the module and substrate rails are releasably connected to each other by at least one connecting element. A spacer gap of sufficient width for operating the connecting element is provided between adjacent solar modules of the plurality of frameless rectangular solar modules.

Abstract: A mounting device for solar modules having a large aspect ratio in a parallel arrangement on a flat horizontal substrate includes mounting rails having through-holes at predetermined locations. Insertion elements are attached to the mounting rails at the through-holes. Each insertion element includes a one-piece shaped element having a contiguous surface interrupted by an insertion slit configured to receive a lengthwise edge area of a solar module, the insertion slit extending at a predetermined insertion angle. A plastic wedge is configured to secure the received lengthwise edge area of the solar module in the insertion slit.

Abstract: 1. Method for determining the distance between two transmitting and receiving stations and transmitting and receiving stations for carrying out the method. 2.1. In automotive engineering transmitting and receiving stations are usually used in keyless locking systems as electronic key modules or evaluation units for identifying the key module. Deactivation of the locking system is prevented if the key module allocated by means of a clear identification number from the evaluation unit is not in the immediate vicinity of the evaluation unit. Communication between the evaluation unit and the key module is carried out by transmitting data telegrams between transmitting and receiving stations. The aim of the invention is to determine the distance between the transmitting and receiving stations in a simple manner. 2.2.
