  • Coupled inductor arrays and associated methods
    Patent number: 9373438
    Abstract: A coupled inductor array has length, width, and height. The coupled inductor array includes a monolithic magnetic core formed of a magnetic material having a distributed gap, and a plurality of windings embedded in the monolithic magnetic core. Each winding forms a respective winding loop of one or more turns around a respective winding axis, and each winding axis extends in the height direction. Areas of the monolithic magnetic core enclosed by the winding loops are greater than areas of the monolithic magnetic core outside of the winding loops, as seen when the coupled inductor array is viewed cross-sectionally in the height direction. One possible application of the coupled inductor array is in a multi-phase switching power converter.

  • Low-power wide dynamic range envelope detector system and method
    Patent number: 7095256
    Abstract: An envelope detector system is disclosed for detecting an envelope in a system input signal. The envelope detector system includes an input node for receiving an input voltage signal, a transconducting amplifier for receiving the input voltage signal and producing an input current signal, a current mirror network for receiving the input current signal and for producing a current output signal, a capacitor for receiving the current output signal, and a rectifier output node for providing a rectifier output current signal. The capacitor is coupled to an input of the transconducting amplifier. The rectifier output current signal is fed into the current-mode wide-dynamic-range peak detector. The peak detector produces the envelope detector output current signal.

  • Moveable hand-held lighted mirror
    Patent number: 5428484
    Abstract: A hand held telescoping mirror device includes a light bulb situated to provide a broad illumination region. The device includes several useful features such as a telescoping arm that retracts within the handle, a twist type on-off switch, and a mirror that's interchangeable with a magnifying glass. In addition, the handle and telescoping arm are separable from the rest of the device so that they may be reconnected to various accessories such as a brush or magnet.
