Ultrarapid Film Systems for Data Display and Computer Interlock
Film systems can greatly reduce requirements for computer memory capacity and operations in automatic checkout equipment. They can also carry binary code data for interlock between the test step description on film and the test routine in a computer. The five dry-process film systems outlined can record, process and project individual frames in less than two seconds. Three of the films are erasable. Some features of computer-operated checkout systems are also useful in educational technology. A narrow-band (240-kHz) audio-visual transmission and sound filmstrip record is proposed as an alternative to educational television.
