The miniature digital communicator is a compact communications device intended for use where conditions are noisy, where no noise at all is permitted or where privacy is desired. It is a portable device with a series of alpha-numeric display elements. Radio-transmitted, digitally formatted data is displayed on the miniature digital communicator in the form of alpha-numeric characters which march or ripple across the display from right to left at an advancing rate of two characters per second. The entire package is small enough to be carried on the person, perhaps in a pocket, like the smallest electronic calculator.
