Abstract: The invention provides an approach for automatic and dynamic mapping of zone boundaries for position-determination systems. The system of the present invention utilizes beacons (“position determining devices”) to identify the boundaries and limits of device area coverage (“zone”) for tracking objects with a position-determination system. Beacons, used both to identify zone boundaries and to tag assets to be tracked, are distributed within the zone. The beacon locations are then detected and displayed in the visualization application. Three or more beacons may be linked together, either manually or automatically, to establish a detection zone. Using beacons to establish detection zone boundaries eliminates guesswork and its associated errors, and produces a zone boundary that is actually valid.

Abstract: A method and device for measuring the angle of inclination on laterally inclined bends and their use.

Abstract: The angle of inclination of a bend encountered by a vehicle is calculated from the rotation rate, lateral acceleration and speed of the vehicle, thereby avoiding the necessity of sensors not already existing in the vehicle.

Abstract: A method for detecting laterally inclined bends being traversed by a vehicle uses a bend-specific value, such as the rotation rate, lateral acceleration or steering angle of the vehicle, the bend-specific value being simultaneously determined by a plurality of different measuring systems. The plurality of determined values are sorted by magnitude to obtain an indication of whether a laterally inclined bend is being encountered by the vehicle.
