  • Preprocessing circuitry apparatus for digital data
    Patent number: 4442542
    Abstract: An apparatus for analyzing line sequential binary data generated by scanning a printed circuit board with a scanning laser apparatus is disclosed. The circuit board contains conducting strips on an electrically insulated substrate. The conductors can be characterized by the number and the locations of their corners and by their widths and by the widths of the substrate occurring between parallel and spaced apart conductors. The line sequential data when viewed together forms a two dimensional image array of the circuit board and the two dimensional array contains information about the conducting corners, widths, etc. The line sequential binary data is first smoothed by smoothing circuits to eliminate errors due to noise, scanning equipment tolerances, etc. Then the smoothed data in line sequential format is transmitted to a corner recognition and pairing circuit where the corner features of the conductors are recognized.
