  • Patent number: 7202801
    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.

  • Patent number: 7072668
    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.

  • Patent number: 7065446
    Abstract: A smart location information processor automatically detects the location of a moving object in real-time, using either a receiver from the satellites or from any terrestrial location detection network. The device processes the location information and activates responsive functions according to location and status. Messages are transmitted through one of multiple wireless communication networks to other units. At any time, the device may receive instructions wirelessly from other stationary or mobile objects. All the events of the installed moving object are stored in a history file which can be sent to a remote server and then cleared from the installed object, either regularly or instantaneously. The device in one object may automatically activate certain functions controlling the object in response to the location of another object installed with the same device.

  • Patent number: 6327533
    Abstract: A method and apparatus for continuously locating moveable objects is presented. In one or more embodiments of the present invention, moving objects can be tracked in real-time anywhere in the world, including inside tunnels. A smart mobile unit in the object receives and uses GPS satellite positioning data when available and relies on its built-in autonomous navigation capability when GPS is invalid to continuously determine its current position in map-ready units. The smart mobile unit transmits the position output, using an automatically selected wireless mode of communication, to a central processing station for map generation and display processing. Authorized clients may log onto the central processing station to view the object or multiple objects from anywhere in the world; all that is required is a computer equipment with a display device and a web browser.
