Abstract: An ignition lock for a motor vehicle includes a carrier element for holding an ignition key that is inserted in the ignition lock. The carrier element is movable along a longitudinal axis of the ignition lock. The carrier element pushes a slide bar from a blocking position to an unblocking position when the carrier element moves along the longitudinal axis. A latch bar, when in its latching position, restricts a movement of the carrier element along the longitudinal axis and, when in its unlatching position, allows the carrier element to move along the longitudinal axis. When the latch bar is in its unlatching position and the slide bar is in its blocking position, the slide bar prevents the latch bar from moving from the unlatching position to the latching position.

Abstract: A method for operating active stabilizers in a motor vehicle includes an on-road mode and an off-road mode. In the on-road mode a stabilizer is activated and deactivated in dependence on operating parameters of the motor vehicle, in particular the travel speed and/or the lateral acceleration and/or a level sensor system, wherein in the activated state rolling motions of the vehicle are reduced by introducing torque into the stabilizer or stabilizers that counteracts the rolling motion. In the off-road mode, the stabilizer is deactivated up to a given travel speed or, in case of an alternate jouncing of the wheels, a control of the stabilizer is performed such that a downward force of the rebounding wheel is increased. Wheel slip may be used as a parameter when controlling the stabilizers. A motor vehicle having active stabilizers is also provided.

Abstract: The invention relates to a method for loading, storing and presenting web pages, by which means the required band widths and the time taken to load web pages for an application are reduced. To this end, components or information elements separate from web pages are provided with indicators by which means the expiry dates can be deduced. The indicators are evaluated by the application which may be a browser. In this way, the application can reload only the updated data/components from the original source. Information elements which are constant over a long period of time can be completed or loaded by the application from a memory associated with the same. The loading times and data quantities for a data transmission from an original source to an application can thus be considerably reduced. The invention also relates to an information system which uses said method, preferably in a motor vehicle.
