Abstract: A system (and method) for conducting a survey, includes a presentation unit for presenting a plurality of choices at a point-of-transaction terminal, an input unit for entering the preferred choices, and a recording unit for recording the entered choices.

Abstract: An information system for a mobile user, includes a source of content information, a proxy server for accessing the source of content information, a wireless communications link coupled to the proxy server, and a mobile computing system coupled to the proxy server via the wireless communication link

Abstract: An electronic billboard system includes a display device coupled with a data processing system to display information, such as advertisements, on the display device. The data processing system is further equipped with a wireless communication interface to communicate with mobile devices. Upon seeing a visual presentation of an advertisement on a display device of the present invention, the user may initiate a request from the mobile device to receive information from the data processing system through a wireless communications link with the wireless communications interface. Information is transmitted to the mobile device and presented to the user.

Abstract: 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.

Abstract: 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.

Abstract: A system and method for vehicle diagnostic and health monitoring includes a client computer device within the vehicle, coupled to the vehicle's monitoring systems, for data management, remote session management and user interaction, a communication system, coupled to the client computer device, for providing remote communication of data including data derived from internal monitoring systems of the vehicle, and a remote service center including a vehicle data store, a server computer, a diagnostic engine, and a communicator for communicating the results of analysis of vehicle information to the client computer device via the communication system.

Abstract: A method for exchanging information between vehicles involved in or near a collision site. When a collision is sensed by one vehicle, a message is transmitted from the one vehicle to at least one of the other vehicles within a threshold distance of the one vehicle. The message contains at least the identity of the one vehicle and preferably driver information, insurance information, along with the time and place of the collision.
