  • Information delivery system using satellite communication
    Patent number: 6484028
    Abstract: An information delivery system includes terminals receiving data via a satellite-communication system, and a user center having a destination-conversion table which lists a satellite-system receiver ID with respect to each ground-network address of the terminals, and, upon receiving a request for data delivery via an intra-network, obtaining satellite-system receiver IDs from ground-network addresses indicated as destinations of the data delivery by referring to the destination-conversion table so as to deliver requested data and a reception-control program to the destinations via the satellite-communication system. The terminals use the reception-control program to check the data-reception conditions when receiving the requested data and the reception-control program, and send a request for a repeat of the data delivery to the user center via the intra-network if the data-reception conditions are not satisfactory.

  • Vehicle data rewrite technique
    Publication number: 20020046344
    Abstract: An electronic control system includes at least an electronic portion and a security flag portion. Operational data is written or rewritten to the electronic portion according to an external standard requiring at least a time delay before rewriting. A security flag portion allows for updating the electronic portion without the time delay where it identifies one of an incomplete initial data write state and a unwritten data write state. After a successful write to the electronic portion the security flag portion identifies the complete written state and requires the delay time before additional rewriting.
