摘要： A mobile navigation system implemented as an embedded system in a vehicle is easy to use, does not detract the driver's attention from the road, and limits the number of choices presented to the user of the navigation system according to a predetermined set of preferences or personalized information. Choices are filtered according to a set of driver preferences, according to the vehicle's geographic position, direction of motion, and the driver's intended itinerary. The itinerary, including intermediate stops, is calculated on an external computing system. The information is downloaded from the computing system to a memory device such as, for example, a smart card. The information is then transferred from the smart card to the embedded vehicle navigation system. In one application of the invention, a kiosk located at a car rental agency may be used to create and store personalized navigation information onto a smart card which the customer then inserts into the vehicle navigation system that is installed in the rental car.

摘要： A system produces of an empirical map of wireless communication coverage through a process of combining information from individual clients to produce a map which is then shared by all of the clients. The wireless coverage map aids in maintaining a reliable communications link. The empirical map is generated by combining information from a group of mobile wireless users. The group may consist of a fleet of trucks, taxicabs, government service vehicles, or the customers of a wireless service provider. The mobile vehicles must be equipped with a GPS device or be located by other means such as triangulation. While vehicles are moving, the quality of wireless communication, e.g., signal strength or communication continuity, is recorded for each vehicle as a function of positions. The data from all of the vehicles is combined to produce the empirical map. The empirical map may be maintained at a central site and subsets of the map replicated for individual vehicles. The map may then be used to direct mobile users to sites of superior communications reliability, warn mobile users when they are out of the service area or are about to leave the service area, or to regulate data communications automatically to stop and restart communications as a mobile vehicle passes through a gap in coverage.
