Abstract

1291992 Optical communication link ENTREKIN COMPUTERS Inc 21 Oct 1969 [21 Nov 1968] 51640/69 Heading G1A [Also in Division G4] An interface assembly for transmitting data from an electrical source to a data processor with reduction of noise, includes transmitting means for converting the data from electrical form to non-electrical airborne form (e.g. light or sound), receiver means for converting the airborne signals to electrical form, and tunnel means substantially enclosing the space between the transmitter and receiver means and formed of electrically-grounded electrically conductive material. The processor (a computer) selects a column of a matrix of controlled rectifiers, which are controlled by respective on/off input data parameters via respective tunnels each as above, to supply the respective inputs to the computer.
