  • Patent number: 6487542
    Abstract: According to the present invention, when electronic money is sent from a given network to another network, a money change apparatus performs a money change process to change electronic money current on the given network into electronic money current on another network, and therefore when a user of the given network uses a settling process, by managing this money change process, it is possible to manage the interchange of electronic money between each of the users of the given network and each of the users of another network without affecting the working environment of electronic commerce. Electronic money current on LAN20 is referred to as local electronic money current only on the network.
    Type: Grant

  • Publication number: 20020067254
    Abstract: In order to allow efficient use of bandwidth in communication paths in a surveillance system, the surveillance system has an operation unit which assigns fixed bandwidths to each of the communications taking place between camera nodes, which transfer image data at a uniform rate, and monitor nodes. A fixed bandwidth is assigned to, all communications taking place between the operation unit and sensor nodes, which generate alarm information at a non-uniform rate. If there is an increase in network traffic, bandwidth allocations, for communication between the camera nodes and the monitor nodes are reassigned so that bandwidth for these communications is reduced. The camera nodes use the bandwidth assigned to the camera nodes to transfer image data. The sensor nodes transfer alarm information using any bandwidth.
