  • Computer interface device
    Patent number: 4725694
    Abstract: A computer terminal device includes a flat screen display element and a touch-sensitive element. Simulated keyboards can be displayed on the display element and, in response to the touching of the simulated keys, generate appropriate control signals. The same flat screen display can also be used to display computer output, either the result of calculations or the result of information retrieval requests. The slim silhouette of this terminal makes it ideal for hostile environments such as the factory floor or the hospital room.

    Inventors: Carol M. Auer, Daniel L. Castagno, Allen W. Haley, Jr., Harry H. Moore, IV, Sean E. O'Leary, Steven J. Paley, Thomas E. Rutt
  • Nonlinear distortion synthesizer using over-threshold power-function feedback
    Patent number: 4710727
    Abstract: A nonlinear distortion synthesizer having an amplifier and one or more over-threshold power-function negative-feedback paths. Each negative-feedback path provides a feedback signal which is separately adjustable for each signal polarity. The feedback signal for each polarity is proportional to a power function of the portion of the output signal which exceeds a predetermined threshold.
