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.

A system and method for transporting the look, feel, and function of one's personalized computer preferences across multiple host computers, including the appearance, settings, programs, and user data. This system and method uses a portable memory device and a data management system that maintains a consistent interface and data file structure on multiple host computers, including a common visual desktop interface. The portable memory solution also provides mobile access to the user's applications and personal data files. The memory device is capable of being connected to multiple host computers via a standard interface such as a USB port.

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.

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.
