Abstract: A method for setting up a virtual ad hoc network for transmitting at least one piece of information to a first transportation vehicle as a first network subscriber. The method includes the information being provided based on first data from at least one second network subscriber, and at least one second network subscriber being a second transportation vehicle or an infrastructure component; wherein a motor-vehicle-external, central data processing device receives second data from multiple potential second network subscribers and takes the second data and at least one space-time parameter as a basis for determining the second network subscribers and setting up the virtual ad hoc network with the first transportation vehicle, as the first network subscriber, and the determined second network subscribers, the space-time parameter defining a specific area of relevance that has a predetermined physical and temporal correlation with the current position of the first transportation vehicle.

Abstract: A magnetic track assembly including an elongate channel having an open side, an end wall, and two parallel side walls; a first magnet disposed within the elongate channel near an interior side of the end wall; a compartment defined within the elongate channel spaced from the first magnet; and a screen receiver disposed within the compartment and including a second magnet arranged facing the first magnet. In the magnetic track assembly, the first and second magnets are of opposite polarity and the screen receiver is loosely disposed within the compartment such that a magnetic bond is intact between the first and second magnets when the first and second magnets are close together and the magnetic bond is broken when the first and second magnets are pulled apart.

Abstract: In one or more arrangements, a retractable screen system is provided. The system includes a roller tube having an exterior surface. A screen is connected to the roller tube and an upper edge of the screen. The screen rolls up around the exterior surface of the roller tube when the roller tube is rotated in a first direction, thereby retracting the screen, and unroll the screen from roller tube when the roller tube is rotated the opposite direction, thereby deploying the screen. In one or more arrangements, the retractable screen system has a roller tube that may be adjusted in length, circumference, and/or shape of the roller edge, for example, to help prevent or mitigate undesirable artifacts that may otherwise become visible stretching of screen material, wrinkling/creasing of screen material, sagging of a roller tube, uneven weight distribution or tension, and/or, bunching of screen materials on a roller tube.
