  • Patent number: 7446643
    Abstract: An electrical protection system, which can be connected between an electrical power supply and an electrical load, firstly includes a switch switchable between a normal state in which the switch is electrically connected in series between the power supply and the load such that an operating current passes through the switch and the load, and a fault sate in which the switch is disconnected with the load such that no current passes through the load. The switch switches to the fault state in an over-current or an over-temperature situation.

    Abstract: A method of deflection routing a packet in an all-optical communication network is described. Routing and destination information is contained in the address header of the packet and is generated by the originating node while still in the electrical domain before conversion to the optical domain. Receiving nodes process the address header in the optical domain using the information for their node from the address header. The address header is comprised of N node fields where N is the number of nodes on the optical network. Each node field contains routing information for a node on the optical network. Each node field contains at least one port field containing routing and address information associated with a port in the node.

  • Patent number: 7410912
    Abstract: Metal oxide nanowires are being investigated to make nanodevices and nanosensors. High operation temperatures or vacuum is required in the manufacturing of metal oxide nanowires by existing vapor phase evaporation methods. This invention provides a method of manufacturing metal oxide nanowires by first providing a metal to form a non-linear substantially planar structure defining a surface. The metal is then heated and maintained at a temperature from 300 to 800° C., and then exposed to oxygen and water vapor containing air stream for a sufficient period of time to form the metal oxide nanowires. The oxygen containing air stream flows in a direction substantially parallel to the plane of the structure. Relatively low temperatures may be used and no vacuum is required in this method, thereby reducing the overall manufacturing costs. Further, this method is able to manufacture different densities of the metal oxide nanowires simultaneously.
