  • Apparatus for determining the two-dimensional connectivity of a prescribed binary variable associated with a surface
    Patent number: 4547898
    Abstract: Apparatus is disclosed which is capable of determining the two-dimensional connectivity profile of a prescribed binary variable associated with a surface. This apparatus comprises a "connectivity-matrix" of switch cells and a two-dimensional sensory array of sensor cells. The sensor cells are responsive to the presence or absence of the binary variable and control corresponding ones of the switch cells in the connectivity matrix.

  • Non-contact X,Y digitizer using two dynamic ram imagers
    Patent number: 4507557
    Abstract: Apparatus is disclosed for detecting the position of an object within a viewing field, such as a CRT display screen. The apparatus includes point sources of radiation arranged at spaced locations around the edge of the viewing field and a retro-reflective surface disposed around the perimeter of the viewing field. The retro-reflective surface reflects radiation received from its originating source back toward this source. A radiation receiver is arranged adjacent to each source to receive the radiation reflected back from the retro-reflective surface and to determine the angular position of an object within the viewing field which interrupts the path of radiation.
