  • Patent number: 6636196
    Abstract: A method is provided for utilizing an M by N matrix array of electro-optic display elements that uses multi-row addressing, the method reducing row artifacts owing to adjacent row cross-talk and improving display performance. The method permits the use of a display device with large pixel count, yet with high display definition and performance.

  • Patent number: 6624807
    Abstract: A manual control device composed of: a housing; a joystick; and a joint supporting the joystick in the housing to enable the joystick to pivot about two mutually orthogonal axes relative to the housing. The joint is an elastic molded plastic part composed of an interior portion secured to the joystick, a peripheral portion secured to the housing and a connecting portion extending between, and connecting, the interior portion and the peripheral portion. The interior portion has the form of a first cylinder and the peripheral portion has the form of a second cylinder, the first and second cylinders being concentric with one another when the joystick is in a neutral position. The connecting portion has a frustoconical shape when the joystick is in the neutral position and is stressed when the joystick is pivoted away from the neutral position.

  • Patent number: 6323832
    Abstract: A color display device in which a plurality of units are arranged in a matrix, each unit having collectively disposed three light emission diodes of three colors, for example, red, yellowish green, and blue, and in which emission intensity and a luminous color of each light emission diode can be controlled by supplying each light emission diode with a time series electric pulse while varying its intensity and width. In the device according to the present invention, the electrodes are provided collectively on one side of the flexible insulator substrate and multilayer wiring is formed by evaporation or plating on the substrate so that the device has an advantage which could not obtained in the conventional display devices in that the display portion thereof can be rolled.

  • Patent number: 5790084
    Abstract: An electronic transparency device is provided with a memory in which a plurality of frames of video data ("slides") can be stored. The apparatus includes a control microprocessor which can cause predefined sequences of slides to be presented on the LCD panel automatically. These slide "shows" are defined by the user using a hand held remote control unit in conjuntion with menus displayed on the LCD panel in window fashion by the microprocessor. The user can specify the duration that each slide in a sequence is to be shown, the video transition by which it is to be introduced, the degree of "windowshading" with which it is to be displayed, etc. Once a show is defined, it can be instituted and controlled from the remote control unit. Among other numerous features, the transparency also includes a pointer that can be superimposed on the display and controlled by the remote control unit. This pointer can be used to define certain portions of the screen that are to be displayed in highlighted fashion.

  • Patent number: 5631666
    Abstract: A detection and hold circuit outputs a reference signal having a level proportional to an x-coordinate detection pulse input from an X-coordinate signal amplifier. A delay element delays the reference signal. An adder adds the x-coordinate detection pulse from the X-coordinate signal amplifier and a delayed signal from the delay element. Comparators obtain a coordinate detection pulse making a detection signal from another detection and hold circuit for an LCD voltage inversion pulse serve as a reference signal. Thus noise following the x-coordinate detection pulse is removed to generate a coordinate detection pulse with a reference value corresponding to the level of the LCD voltage inversion pulse to allow a stable coordinate detection to be achieved.

  • Patent number: 5583541
    Abstract: A mouse or track ball has a roller ball mounted within a housing by three free rollers in contact with an outer peripheral surface of the roller ball. An inner core of the roller ball is provided of a magnetic material having either bumps or holes at an outer periphery thereof. The inner core is coated with a non-magnetic material providing an outer smooth and round surface for the ball.

  • Patent number: 5504499
    Abstract: After an initial starting single color may or may not be provided, the user may indicate a global sensation, such as morning, so that all colors inputted thereafter will be modified by the global sensation, or input a basic color, such as blue. In either case, menu driven user input information may include any number of human sensations relating to color for modifying the previously compounded color. In each case, the newly compounded color is displayed in a color display area on the screen. Thus formed, new colors may be named and stored to be retrieved at a later date. The menus on the display screen may be grouped according to basic decisions, basic colors, and compounding modifications according to human sensations, which latter may be subgrouped according to specific types of sensations such as mood, feeling, temperature, and the like.

  • Patent number: 4845482
    Abstract: The elimination of crosstalk between data lines and pixel cells in a thin film transistor/liquid crystal display is accomplished by applying a data signal to a given data line for a time period less than the standard scan line period of the display, and applying a crosstalk compensation signal to the given data line for the remainder of the scan line period.
