    Abstract: Apparatus and method for determining when a vehicle has arrived or departed from a planned or an unplanned stop, while minimizing or completely eliminating driver intervention. The apparatus comprises a mobile communication terminal located onboard a vehicle for receiving destination information, generally using wireless means, from a central facility or hub. A speedometer also located onboard the vehicle determines the speed of the vehicle and a position sensor onboard the vehicle determines the vehicle position. The vehicle speed and position are provided to a processor, also located onboard the vehicle, which uses the speed and position information to determine a vehicle arrival or departure from a planned or unplanned stop. The processor generates an indication of the event, either arrival or departure, directly to the central facility, to the vehicle operator, or both.

    Abstract: Apparatus and method for determining when a vehicle (108) has arrived or departed from a planned or an unplanned stop, while minimizing or completely eliminating driver intervention. The apparatus comprises a mobile communication terminal (202) located onboard a vehicle (108) for receiving destination information, generally using wireless means, from a central facility or hub (104). A speedometer (210) also located onboard the vehicle (108) determines the speed of the vehicle and a position sensor (212) onboard the vehicle (108) determines the vehicle position. The vehicle speed and position are provided to a processor (206), also located onboard the vehicle (108), which uses the speed and position information to determine a vehicle arrival or departure from a planned or unplanned stop. The processor (206) generates an indication of the event, either arrival or departure, directly to the central facility (104), to the vehicle operator, or both.

    Abstract: A novel and improved method for implementing a high-transmission-rate over-the-air interface is described. A transmit system provides an in-phase channel set (90) and a quadrature-phase channel set (92). The in-phase channel set (90) is used to provide a complete set of orthogonal medium rate control and traffic channels. The quadrature-phase channel (92) set is used to provide a high-rate supplemental channel and an extended set of medium rate channels that are orthogonal to each other and the original medium rate channels. The high-rate supplemental channel is generated over a set of medium rate channels using a short channel code. The medium rate channel are generated using a set of long channel codes.
