ABSTRACT:
An electro-optical signaling system and associated method is disclosed for communicating numerical information, such as time of day or ambient temperature, to an observer. The signaling system comprises a linear array of flashing lights, established in a vertical direction, each light being connected in parallel to the output of a microprocessor for controlling the energization of the lights and the sequence thereof. With individual lights being normally "off" and under the control of the microprocessor, energization signals are delivered to the light array in accordance with a control algorithm to turn selected lights "on" and then "off" in a predetermined, serial sequence so that the array as a whole may display a coded message indicative of numerical digits.
