  • Patent number: 10332640
    Abstract: A toroidal field coil for generating a toroidal magnetic field in a nuclear fusion reactor includes a toroidal plasma chamber having a central column. The toroidal field coil has a plurality of windings configured to pass through the central column and around the outside of the plasma chamber. Each winding includes a cable having a plurality of stacked high temperature superconductor (HTS) tapes, each HTS tape including one or more layers of a high temperature superconductor material. With the toroidal field coil in place in the reactor, a face of each HTS tape is substantially perpendicular to a direction of maximal neutron flux during reactor operation as the cable passes through the center column.

  • Publication number: 20150066529
    Abstract: A workflow management system includes a processor and memory. The memory stores instructions that, when executed by the processor, cause the processor to identify an event received from an external system. The instructions further cause the processor to generate a work item corresponding to the event. The work item has a plurality of attributes. The instructions further cause the processor to assign the work item for distribution based on the attributes, and adjust at least one of a priority or a routing strategy for the work item according to a status of the work item.

  • Publication number: 20070004055
    Abstract: A method and circuit for managing thermal performance of an integrated circuit. Temperature sensing circuits and a plurality of power FETs that are coupled together in parallel are manufactured from a semiconductor substrate. Each temperature sensing circuit monitors the temperature of the portion of the semiconductor substrate near or including a corresponding power FET. When the temperature of the semiconductor substrate near one or more of the power FETs reaches a predetermined value, the corresponding temperature sensing circuit reduces a voltage appearing on the gate of the power FET. The reduced voltage increases the on-resistance of the power FET and channels a portion of its current to others of the plurality of power FETs. The power FET continues operating but with a reduced current flow. When the temperature of the semiconductor substrate falls below the predetermined value, the gate voltage of the power FET is increased to its nominal value.

  • Patent number: 7099135
    Abstract: An inrush current limiter circuit (20) includes a detection circuit (30) that produces a control signal (VDRIVE) from a sense current (ISENSE). A power transistor responds to the control signal and has a source (51) coupled to an input node (12) to receive a supply voltage (ground) and a drain (53) for routing a load current (ILOAD) to an output node (45) as a protection signal (VSW). A sense transistor responds to the control signal and has a source scaled to the source of the power transistor and coupled to the input node to route a portion of the load current to the output node as the sense current.
