Remote access to schematic drawings
An electronic information system for storing, transmitting, receiving and displaying electrical circuit schematics is presented. The schematics are binary coded for computer storage and for transmission over telephone grade communications lines. A complete schematic can be transmitted in a matter of a few seconds with no degradation in the image quality. A standard set of schematic symbols and the associated alphanumeric characters are stored at the receiver in the character matrix of a shaped beam tube. Only the information as to the location of each schematic symbol in the character matrix and the organization of the schematic symbols is stored and transmitted.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/33071/1/0000457.pd
