  • Roping And Moire Reduction In Patterned Screen Cathode Ray Tube Displays

    view source
  • US Patent:
    44108419, Oct 18, 1983
  • Filed:
    Sep 28, 1981
  • Appl. No.:
    6/306452
  • Inventors:
    Christopher R. Dusard - Phoenix AZ
    Thomas W. Spilsbury - Phoenix AZ
  • Assignee:
    Sperry Corporation - New York NY
  • International Classification:
    H01J 2958
  • US Classification:
    315382
  • Abstract:
    In a patterned screen color cathode ray tube (CRT) display, for example, a shadow-mask type color CRT, particularly for use under a wide range of ambient light conditions, such as an aircraft cockpit, incompatibilities between the screen pattern character, the type of writing (such as stroke and raster), and the display linewidth, may result in stroke written lines which appear as a twisted fiber rope and in raster written areas which appear wavy or watery; that is, a moire appearance. Both of these effects vary in accordance with the required display brightness over the ambient light range due to variations in beam or linewidth with corresponding variations in the required cathode drive voltages. These undesirable roping and moire effects are eliminated or substantially eliminated by varying the electron beam focus in accordance with a computed reference brightness compatible with the range of ambient brightnesses in a manner to maintain a predetermined, substantially fixed beam width for stroke written symbols and effective line spacing for raster written symbols.
  • Cathode Ray Tube Beam Deflection Amplifier System

  • US Patent:
    42976219, Oct 27, 1981
  • Filed:
    Oct 2, 1980
  • Appl. No.:
    6/193236
  • Inventors:
    Thomas W. Spilsbury - Phoenix AZ
  • Assignee:
    Sperry Corporation - New York NY
  • International Classification:
    H01J 2970
    H01J 2976
  • US Classification:
    315397
  • Abstract:
    A cathode ray dual mode electromagnetic beam deflection amplifier system for providing current for driving a deflection coil, and means for switching between linear and resonant non-linear operational modes. In the linear mode, the deflection coil current is controlled to closely follow an applied input deflection sweep voltage and operates as a push-pull amplifier. In the non-linear resonant mode, one-half the output stage is abruptly decoupled from the deflection coil such that energy stored in the deflection coil is discharged into a series capacitor, the subsequent resonant pulse being returned through the non-decoupled half of the output stage to a power supply.
  • Dynamic Focus Control And Power Supply For Cathode Ray Tube Displays

    view source
  • US Patent:
    42582989, Mar 24, 1981
  • Filed:
    Dec 28, 1979
  • Appl. No.:
    6/107986
  • Inventors:
    Hugh C. Hilburn - Glendale AZ
    Thomas W. Spilsbury - Phoenix AZ
  • Assignee:
    Sperry Corporation - New York NY
  • International Classification:
    H01J 2958
  • US Classification:
    315382
  • Abstract:
    Apparatus is provided for effecting automatic dynamic compensation of the focal characteristics of electron beam tubes having substantially flat viewing faces, compensation in terms of two dynamic inputs including low frequency components primarily representing display brightness and high frequency components primarily representing electron beam displacement.
  • Anode Voltage Deflection Gain Control For Cathode Ray Displays

    view source
  • US Patent:
    42976189, Oct 27, 1981
  • Filed:
    Sep 15, 1980
  • Appl. No.:
    6/187039
  • Inventors:
    Thomas W. Spilsbury - Phoenix AZ
  • Assignee:
    Sperry Corporation - New York NY
  • International Classification:
    H01J 2956
  • US Classification:
    315371
  • Abstract:
    A compensating gain control system provides improved operation of the deflection channels of cathode ray color displays, particularly a display of the penetration phosphor type. A sample of the indicator anode voltage is taken and the square root of the sample is derived. Each deflection current wave form is multiplied by the square root signal, thus providing a deflection drive current accurately scaled to anode voltage changes.
  • Deflection Amplifier System For Raster Scanned Cathode Ray Tube Displays

    view source
  • US Patent:
    43027083, Nov 24, 1981
  • Filed:
    Mar 31, 1980
  • Appl. No.:
    6/135372
  • Inventors:
    Thomas W. Spilsbury - Phoenix AZ
  • Assignee:
    Sperry Corporation - New York NY
  • International Classification:
    H01J 2970
  • US Classification:
    315389
  • Abstract:
    An efficient cathode ray deflection amplifier is provided having a selectable scan rate capability, providing sweep rate linearity through the use of a feed back arrangement that also cooperates in a self-adaptive manner with respect to commanding changes in the raster scan rate or display size.
