  • Input equipment with sensed movement feedback
    Patent number: 7098890
    Abstract: The present invention discloses an input equipment with a sensed movement feedback, which comprises a pressure sensor pad having a through hole at the center, a rolling ball disposed in the through hole with part of the rolling ball exposed and protruded therefrom, and at least one driver contacting with the surface of the rolling ball. The sensor pad will produce a signal according to a pressing force exerting thereon and transmit the signal to a control circuit of the input equipment, enabling the control circuit to produce a rolling signal for activating the driver to move the rolling ball in a direction proportion to the pressing force. Thus, the user can sense the direction and speed of the cursor movement on the screen from sensing the rolling movement of the rolling ball.

  • Method for converting monochrome images
    Patent number: 6961068
    Abstract: A method for converting monochrome images to color images. A monochrome image is blocked first, and pixel values of monochrome image blocks are obtained by statistical analysis. The monochrome image is then processed by layered mapping and color values of equal grayscale layers thereof are obtained. Finally, each monochrome image block is matched to a color of a corresponding equal grayscale layer.
