  • Calculations of coordinates of target image displayed on monitor screen
    Patent number: 6816631
    Abstract: Coordinates of a target are calculated by measuring time between the generation of a vertical synchronizing signal fetched from a composite signal for displaying the target image on a video monitor and a singular change of a video signal and calculating the coordinates of the target image displayed on the video monitor from this measured time. In this way, the coordinates of the target image where it is displayed on the video monitor can be calculated very rapidly.

  • Visual control robot system
    Patent number: 6763283

The position of the robot and its target are determined by video cameras placed to take images of the entire moving area of the robot from at least two directions and a control circuit for interpreting those images.
