  • Patent number: 6359894
    Abstract: A remote communications server system enables multiple remote users simultaneous access to a network. The system connects a plurality of on-line sessions across multiple communication lines to the network. A unique combination of multiple buses, multiple processors, and a segmented design creates a distributed processing communications system having high throughput without the stability problems associated with gigabit bus speeds. Furthermore, the system supports a mixture of communication links and allows the substitution of one service type for another without affecting the remaining communication links. The system is scalable in that segments can be added as needed and the number of lines handled by a segment can be increased.
    Type: Grant

  • Patent number: 6030603
    Abstract: This invention relates to an oil-in-water emulsion that is of a water-insoluble gas-forming chemical and a stabilizer. The emulsion being capable of forming microbubbles of gas upon application of ultrasonic energy. This composition allows for site specific imaging as the image enhancing microbubbles can be released upon the application of ultrasonic energy at the specific location where the image is desired.

  • Patent number: H2065
    Abstract: A proxy server shares a plurality of modems connected to a wide area network among multiple client computers connected to a local area network. Each of the client computers on the local area network is assigned a local address while each of the plurality of modems is assigned a modem port address valid on the wide area network. In one embodiment, a processor controls address substitution allowing multiple client computers to share modems when communicating to host computers in a wide area network. The processor creates a descriptor list to keep track of the connections between the client computer and host computers on the wide area network and uses the descriptor list to determine to which client computer an incoming data packet should be sent. The processor also creates a proxied application list to determine if an outgoing data packet, received from one of the client computers, is one to be proxied through the proxy server.
