    摘要: A frequency compander for improving the frequency response of a telephone line when used for remote broadcasting. The inventive device comprises an encoder for compressing the frequency spectrum of an audio signal and a decoder for expanding the signal back to its original spectrum. Preferably the encoder comprises: an anti-aliasing filter; an A/D converter for digitizing incoming audio; a DSP for compressing the audio; and a D/A converter for outputting compressed audio to the phone line. The decoder comprises: an anti-aliasing filter; an A/D converter for digitizing the incoming compressed signal; a DSP for restoring the original audio; and a D/A converter for outputting program audio. In a preferred embodiment, encoding and decoding are performed in the frequency domain. In another preferred embodiment, encoding and decoding are performed in the time domain using trigonometric transformations.

    摘要: A quantum tunneling transistor which provides two switching inputs, for example source and drain as with a conventional FET, and a control input which, in one embodiment, performs much like the gate input of a conventional FET. In one embodiment, charge pump circuitry is integrated onto the semiconductor substrate material of the transistor to provide a plurality of switching voltages to the transistor. The circuitry is configured such that switching of the transistor is controlled by a single, high impedance input, thus allowing the use of the quantum tunneling transistor in existing applications.

    摘要: An integrated computer management and storage system comprising, in a preferred embodiment: an external mass storage device for a host computer; including a power storage sub-system, in the form of a capacitor or battery, such that during an intermittent communication breakdown, it has energy to sustain the static RAM values stored in the registers of the mass storage device for a sufficient period of time, thereby allowing for the option of reconnection, without re-initialization; and an associated mass storage device driver, typically residing on the host computer, capable of re-polling and restoring the connection without re-initialization. Optionally, a redundant backup of the static RAM values may also be stored on the host computer device.
