  • Patent number: 6147670
    Abstract: A structured screen display process presents structured information that includes a plurality of elements on any width screen display so that the user is able to see as many of the elements as possible at once, and is able to see the complete text of any element as needed. The process dynamically adapts the display of structured information to the screen display width of the device. Further, in this dynamic adaptation, the user sees at a glance as many as possible of the elements of the structure, and the user can see any of the elements at the user's discretion in a way which is compatible with using structured information such as a menu of choices. The structured information is presented on a screen display by displaying at least a portion of each element in a plurality of elements on the screen display where at least one of the elements has a width greater than a width of the screen display.

  • Patent number: 6025829
    Abstract: An image generator generates brightness modulated bars for a video monitor. The bars run parallel to the scan line of the monitor allowing the use of a relatively slow digital to analog converter (DAC). A frame buffer need only be as deep as a number of different shades desired on a particular scan line, instead of needing to be as deep as the resolution of the DAC. Using a multiplexer allows use of a 1 bit deep frame buffer instead of a conventional 12 bit deep frame buffer. A feature of the image generator allows efficient determination of a mean gray scale used in generating the brightness modulated bars. The brightness modulation scheme is sinusoidal, that is, based on a sine function, for specified applications but can be any other modulation scheme based on, for example, a sawtooth function, a step function, an exponential function, and so forth.

  • Patent number: 5956015
    Abstract: The color matching methods and systems according to the current invention accomplish accurate color matching by separating causes for creating color discrepancies in a predetermined color patch on an image-carrying medium and a color monitor display. In general, the chromaticity values of the predetermined color patch are measured under a standard calorimeter light source whose luminance is different from that of ambient light. The corresponding color is displayed based upon the luminance of the standard light. However, ambient light does not generally have the above luminance. Thus, when the color display is compared against the color patch under ambient light, the colors do not appear identical. To solve this and other problems, the current invention discloses methods and systems to adjust the display signals based upon the luminance of ambient light.

  • Patent number: 5923319
    Abstract: A front cover assembly is provided for use with a touch sensitive display device. The touch sensitive display device includes a display such as a Cathode Ray Tube (CRT) or Liquid Crystal Display (LCD). The front cover assembly has a top cover, an infrared bezel and a piece of glass. The top cover is inserted into a mold along with the piece of glass. The top cover and glass are then held in place by a vacuum while polyurethane is injected to fill the void between the glass and the top cover and the mold. The polyurethane is injected using injection molding techniques. The polyurethane used must have the properties of flexibility, durability and must also be transparent to infrared light. The polyurethane provides a mechanical lock around the glass and top cover and thus the polyurethane compensates for the different rates of expansion and contraction of the glass and the top cover due to temperature variations in the ambient environment.

  • Patent number: 5920302
    Abstract: A display scrolling circuit is provided which can give a variety to a display image by scrolling the display image for every display line without provision of a burden on a processor for computing a game. A game system to which the present invention is applied has a CPU 10, a video RAM (VRAM) 12, a character generator (CG) 14, scroll registers (SR) 16, 18, 20 and 22, a VRAM address control circuit 30, a CG address control circuit 32, an in-character transverse correction circuit 34 and a color palette 36. The VRAM 12 stores vertical and horizontal position data for every display line and absolute flags AF indicating whether these vertical and horizontal position data are absolute or relative values. The VRAM address control circuit 30 reads the position and other data from the VRAM 12 during the horizontal blanking period to set the read addresses of the VRAM 12 required to display one line. Therefore, the amount of scrolling for every display line can be set without provision of a burden on the CPU 10.

  • Patent number: 5910791
    Abstract: A method and a control circuit for controlling a field emission display to reduce emission to grid during turn on and turn off are provided. In an illustrative embodiment, the control circuit includes a threshold detector that receives an input signal proportional to an anode voltage (V.sub.Anode) for the display and produces a high or low output signal dependent on the level of V.sub.Anode. An output low corresponding to a high voltage at the display screen enables a gate element of a pass transistor that controls current flow to the grid. Alternately, an output high corresponding to a low voltage at the display screen enables a pull down transistor that controls discharge of the grid to ground. The control circuit can also include a fault detection circuit for detecting a sharp decrease in the anode voltage and discharging the grid.
