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.

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.

Abstract: An ice cream maker for making ice cream having a vessel, a motor being connected to a dasher in the vessel and a housing for housing the vessel and the motor. The housing has an inlet, an outlet and a valve at the outlet. When said valve is actuated, the ice cream is released from the vessel out of the outlet.
Abstract: In one embodiment, a protection device is used to protect a circuit. The protection device has a maximum rated power dissipation that is less than a maximum rated power dissipation of the circuit that is being protected.
Abstract: In one embodiment, an LED control circuit is configured control a current through an LED responsively to a value that is proportional to a control signal for values of the control signal that are less than a threshold value of the control signal and to control the current to a value that is proportional to the threshold value for values of the control signal that are greater than the threshold value.
Abstract: A computer can include a high-resolution color display, built-in keypad, wireless LAN connection, hi-fidelity audio system, and a multi-gigabyte disk drive. The screen can be formed in a top face of a computer and a keypad can be a split on opposite sides of the screen. The computer can also have various other controls and features, including function keys, scroll wheel, game D-pad, stylus, and fingerprint reader. Speaker covers for built-in speakers can be provided in the top face.

Abstract: In one embodiment, a current regulator is configured to form a first signal representative of a current flow through a power switch and to use the first signal to determine an off-time of the power switch.
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.
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.
