    摘要： 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.

    摘要： 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.

    摘要： A remote tire monitor system includes a control unit and a plurality of tire monitors mountable on respective wheels of a vehicle to transmit radio signals to the control unit. The tire monitors each include a pair of motion sensors such as shock sensors and a control circuit configured to determine position information for the respective tire monitor based on first and second shock sensor signals from the pair of shock sensors. The shock sensors produce an output voltage proportional to a change in applied force. Therefore, the offset created by centrifugal force in previously used accelerometers is absent, simplifying design of the tire monitors.

    摘要： An inexpensive, practical hygienic finger protector is provided, which includes a tubular sheath having a proximal open end and a distal closed end. The open end is adapted to receive a human finger to approximately the first joint with the tip of the finger, when inserted, abutting the closed end. The finger protector further includes a knob-like protuberance imbedded into the closed end of the sheath, disposed below the downward-facing fingertip of the inserted finger. The finger protector guards against contamination by dirt or microorganisms, while allowing the wearer to input data or signatures into public data input devices such as keypads or s keypads, card readers, and signature recorders. Optionally aspects, including a keychain attachment, embedded data storage, and aesthetic cut-outs are presented.
