  • Publication number: 20040063388
    Abstract: A disc repair system which is provided for the purpose of consumer-repairing of scratches on optically-read discs (e.g., digitally recorded discs, known commonly, as “CD” discs or “DVD” discs, etc., containing audio or video or other formats of data information), such that an optical reader, which uses a laser to read digital information stored on a compact disc, can read the digital information without the optical distortion caused by a scratch. The system utilizes diamond grit as an abrading compound to recondition the disc surface.

  • Publication number: 20020102919
    Abstract: A disc repair system embodied by a consumer kit, which is provided for the purpose of consumer-repairing of scratches on optically-read discs (e.g., digitally recorded discs, known commonly, as “CD” discs or “DVD” discs, containing audio or video or other formats of data information), such that an optical reader, which uses a laser to read digital information stored on a compact disc, can read the digital information without the optical distortion caused by a scratch. The consumer kit (in a special box package) contains a hand-held rotator which is preferably used in combination with abrading compounds, abrasive discs, and wiping cloths to recondition the disc surface.

  • Patent number: 4912642
    Abstract: An integrated engine control-autothrottle control system for controlling changes in the thrust of a jet aircraft engine during transients (i.e., changes in speed) in a manner that prevents throttle lead and overshoot (i.e., exceeds the response capability of the engine) is disclosed. The system uses the engine control to continuously monitor current fuel flow (WF), burner pressure (PB), high rotor speed (N2) and engine thrust (EPR), manipulates the signals and produces limiting fuel flow transient error (WFPBERR) and rotor speed transient error (N2DOTERR) signals for both acceleration and deceleration. The lower parameter transient error signal is selected as the controlling limit signal during acceleration and the higher parameter transient error signal is selected as the controlling limit signal during deceleration. The controlling limit signals are used to produce limiting throttle lever angle rate of change signals--+TRADOT for acceleration and -TRADOT for deceleration.
