Abstract: A method for distributing locating-relevant information includes providing a GPS position of a client to a server on a data network, and returning location-relevant information by the server based on the specified GPS position. Such location-relevant information include travel or tourist information (e.g., locations of tourist attractions, hotels, or restaurants). Commercial information such as discount coupons or advertising selected based on the Client's GPS position can also be provided. Financial or business transactions can be conducted using the GPS position for authentication or identification.

Abstract: A method and a system using the Global Positioning System (GPS) to detect and report vehicle accidents are presented. GPS, which is currently used primarily for vehicle positioning, can be combined with wireless technology to automatically report accidents to third parties. A mobile unit placed or installed in a vehicle receives code sequences from the GPS satellites, converts the code sequences to positional information, and transmits the positional information to a server. The server derives the acceleration of the mobile unit from the positional information and compares the acceleration with a threshold value. In one embodiment, a microprocessor included in the mobile unit derives the acceleration and compares the acceleration with a threshold value. The threshold value represents acceleration that can be achieved only with an external force such as a collision.

Abstract: A drag-type road grader including a skewable frame and a plurality of blade assemblies extending transversely across the frame. A tongue assembly is mounted on the frame and includes hydraulic cylinders for skewing the frame to alternative parallelogram-shaped configurations whereby the blade assemblies are angled with respect to the direction of travel. Retractible wheel assemblies are provided for transporting the grader in a non-working mode.
