Smart Cross Programmable Vehicle and Pedestrian Signage With Electronic Display and Infrared Remote Control

1. A portable programmable vehicle and pedestrian traffic control sign, said traffic control sign comprising: an electronic display means having a plurality of light emitting diodes which can be either energized or not energized in such a fashion as to form various letters of the alphabet or special symbols; a digital electronic control means having input and output modules, a microprocessor to accept digital inputs and to process digital inputs according to operational program steps, and a display driver to control the operation of the light emitting diodes of the electronic display; a digital storage means for storing digital programs which control the operation of the microprocessor; an infrared receiver means to receive infrared signals from a remote infrared transmitter and convert such signals into digital signals supplied to the digital electronic control; an infrared transmitter means to convert push button operator inputs into infrared control signals which are transmitted to the infrared receiver; an electrical power means to provide electrical power to the electrical components of the sign; an enclosure means consisting of a front face transparent to the passage of light from the illuminated light emitting diodes of the electronic display, an opaque back face, two opaque side walls, an opaque top wall and an opaque bottom wall joined in such a manner as to provide a dust free and weatherproof environment for the electrical and electronic components of the sign; a support tube extending from bottom wall of the enclosure of sufficient length to elevate the electronic display for greater visibility; and a base means attached to the support tube and having attached legs extending outward radially from the center of the base and lying in a horizontal plane to provide a stable platform for the sign.

2. The traffic control sign of claim 1, wherein the electronic display means consists of light emitting diodes of a plurality of colors such that the letters and symbols formed by the electronic display can be made to appear in the normal color of the safety condition displayed.

3. The traffic control sign of claim 1, wherein the transparent front face of the enclosure includes an ultraviolet coating to reduce glare and to enhance the visibility of the display.

4. The traffic control sign of claim 1, wherein the sign includes an audio transducer mounted in a side wall of the enclosure and under the control of the microprocessor to produce audible messages duplicating the message displayed on the electronic display.

5. The traffic control sign of claim 1, wherein the opaque back face of the enclosure is replaced by a translucent back face and a second electronic display under the control of the microprocessor such that a second message can be simultaneously displayed in a direction directly opposite to that of the first display.

6. The traffic control sign of claim 1, wherein the support structure includes a universal clamping structure to replace the base which allows the sign to be clamped to an existing vertical or horizontal pole or traffic control support structure.
