Abstract
Abstract A portable programmable sign comprising a unitary T-shaped housing having opposed front and rear sides and including an upper sign portion and a lower hand-held portion mounted midway transverse to the sign portion. A keyboard system with a miniaturized keyboard processor including keys marked with indicia for letters of the alphabet, numerals, and other selected indicia is mounted on the hand grip for operator input. Operating keys are also mounted on the keyboard. The sign includes a miniaturized computer microprocessor for processing input data received from the keyboard. A miniaturized light-emitting message display, preferably an LED display, is mounted on the front side of the sign portion for reading by an observer. An electrical circuit in the housing joins the keyboard system, computer microprocessor, and the light-emitting message display are joined by an electrical circuit in the housing and which can be internally or externally powered. An optional miniaturized monitor display system mounted on the rear side of the sign portion receives the input data from the computer microprocessor prior to transmission of the input data so that a user can edit or verify the accuracy of the input data prior to transmission of the data to the light-emitting message display.
