Abstract: A real-time management and dispatch system includes a controller configured to control data flow and processing of management and dispatch operations. A database server is configured to control storage, organization, retrieval, and distribution of management and dispatch data. At least one workstation is configured for accessing dispatch functions and management functions. At least one Global Positioning System (GPS) enabled handheld device is configured to receive and transmit dispatch information over a local wireless communication network. The local wireless communication network provides real-time information transmission between the controller, at least one work station, and the at least one handheld device.

Abstract: An automated, location-based, dynamic notification system comprises a mobile unit hardware device and a control center computer facility with communication capabilities. The mobile unit comprises a position module, a location processor, an action processor, a data module, and an I/O module. The control center comprises a system processor, a communication module, and a master database. The system provides notifications of arriving, approaching, leaving, entering, and any other types of location-related notifications, which are issued in an automatic, unattended manner. The illustrated embodiments of the invention are based on location and thus are used in a dynamic routing situation where both route patterns and stop locations change frequently while the object is moving.

Abstract: A communication system for tracking an asset globally accesses multiple communication networks and switches among them, choosing the most economic, available communication mode without need for a constant power supply. An integrated motion sensor uses a combination of GPS updating and dynamic movement calculation to obtain the most reliable position estimation. Current location is identified within a small radius at all times. While taking advantage of the GPS system to obtain accurate location information, direct exposure to GPS satellites is not required at all times. The system obtains position information from GPS satellites whenever valid GPS signals are available, and provides its own location tracking capability when GPS signals are not accessible. The position accuracy of the device is preferably within a 20-meter radius from the exact location.
