A method for high-precision position determination for vehicles, wherein the vehicles include devices for wireless communication with intelligent infrastructure devices, the precise position of the intelligent infrastructure device being known and the vehicles exchange status information with the intelligent infrastructure devices at predefined time intervals, and wherein the intelligent infrastructure devices have devices for determining the direction of the received signals carrying the status information, in which the status information sent from the vehicles to the intelligent infrastructure devices includes at least the vehicle identifier and information about the speed and the direction of the vehicle, and in which the position of the vehicles is determined via trigonometric methods from consecutive sets of status information, the associated known time intervals, the direction of the signals carrying the status information and the position of the intelligent infrastructure devices.

High-precision position determination for vehicles

The invention relates to a radio transmission/radio reception device and to a method for communication within a, in particular wireless, motor vehicle communication system interacting in ad-hoc fashion which are configured such that the radio transmission/radio reception device emits a piece of information about the scope of envisaged reports, at least one further radio transmission/radio reception device receives the information, and the further radio transmission/radio reception device takes the received information as a basis for stipulating a frequency for the emission of chronologically successive reports.

A liquid crystal display having a liquid crystal cell ( ) has electrical heating formed by an electrically conductive heating layer ( ) on a substrate ( ). On opposite sides, a clamp ( ) forming a busbar in each case reaches over the substrate ( ) and bears on the heating layer ( ) by a limb ( ). For connection to the heating current source, a spring element ( ) is arranged between a limb ( ) of the clamp ( ) and a printed circuit board ( ).

Indicating instrument

An invention relates to an indicating instrument, in particular for a motor vehicle, having a housing with a front frame holding a cover pane, and an elastic spacing element arranged between the cover pane and front frame, and a method for connecting the cover pane to the front frame. In order to ensure a reliable connection between the cover pane and front frame which is without play, the spacing element be is placed in an axial cutout which is arranged in the region of the circumference of the front frame and faces the cover pane, and in which the cover pane can engage. The method consists in that in a first step the spacing element is inserted into the axial cutout in the front frame, and in a second step the cover pane is pressed into the axial cutout against the spacing element.

A plug socket ( ) has a plug housing ( ) with a baseplate ( ). The baseplate ( ) has a respective contact surface ( ) on two opposite sides in order to seat it on a printed circuit board. A contact spring ( ) has two support regions ( ) which are curved in the shape of an arc in opposite directions and which together form the shape of an S lying on its side. The contact spring ( ) permits conductor track contact both in the case of surface mounting and plug-in mounting for the plug socket ( ).

A combination instrument (,) has a front frame (,) having a cover (,) which has a plurality of recesses (,) for indicating instruments or other displays. The cover (,) is covered with a decorative element which is formed as a molding (,) and around which a section (,), which is designed as an undercut, of the front frame (,) grips. To this end, the front frame (,) is produced in an injection molding process, the molding (,) being placed into the injection mold. The connection of the molding (,) to the front frame (,) can take place such that it is invisible to someone looking at it, thereby enabling an attractive, visual appearance and simultaneously reliable way of fixing it to be achieved.
