    摘要： A physical layer transmitter that communicates between nodes in a broadband cable network by transmitting and receiving packets containing data and control information. Packets are constructed by the physical layer transmitter and transmitted to one or more receiving nodes that are capable of processing the packets. Packets are directed to specific nodes utilizing link layer control data. The packets may also contain control information that may include formatting, encoding and modulation parameters that are capable of being processed by the appropriate receiving nodes. The physical layer transmitter allows node-to-node communication within a broadband cable network and each node in the network is capable of communicating with every other node in the network.

    摘要： A hydrogen storage system for storing hydrogen gas at elevated pressures and cryogenic temperatures is disclosed. The hydrogen gas is fed to a storage container which contains a physisorption type material and a volatile liquid container for liquid nitrogen. Cryogenic conditions are maintained within the storage container during the periods of storage and the periods where the hydrogen gas is removed from the storage system.

    摘要： A multi-bath apparatus and method for cooling a superconductor includes both a cooling bath comprising a first cryogen and a shield bath comprising a second cryogen. The cooling bath surrounds the superconductor, and the shield bath surrounds the cooling bath. The cooling bath is maintained at a first pressure and subcooled, while the shield bath is maintained at a second pressure and saturated. The cooling bath and the shield bath are in a thermal relationship with one another, and the first pressure is greater the second pressure. Preferably, the cryogens are liquid nitrogen, and the superconductor is a high temperature superconductor, such as a current limiter. Following a thermal disruption to the superconductor, the first pressure is restored to the cooling bath and the second pressure is restored to the shield bath in order to restore the superconductor to a superconductive state.

    摘要： A method for authentication of a first client in communication with a second client via an authentication server is disclosed, such that the first client and the second client are authenticated to each other, and the authentication server is authenticated to both the first client and the second client. The ability of a client and an authentication server to generate a one-time-use key unique to the client for a given request, is used as the basis for authentication. The flow of requests and responses coupled with each client's unique one-time-use key, such as a one time use account number used to encrypt messages, results in all three entities, the two clients and the authentication server, mutually authenticating each other. The method effectively prohibits a “man-in-the-middle” attack, wherein an unauthorized entity tries to assume the roll of one of the two clients, or the authentication server.
