MULTI-BRAKELIGHT ARRAY CONTROL EQUIPMENT

THE EQUIPMENT WAS DEVELOPED FOR THE EVALUATION OF MULTI- BRAKELIGHT DISPLAYS. BASICALLY IT CONSISTS OF AN ARRAY OF LIGHTS WHICH CAN BE SWITCHED ON IN ACCORDANCE WITH THE VEHICLE'S DECELERATION. THE APPARATUS CAN BE READILY PROGRAMMED TO SEQUENTIALLY DISPLAY A NUMBER OF GROUPS OF LAMPS IN RESPONSE TO PRESENT VALUES OF VEHICLE DECELERATION. EACH GROUP OF LAMPS CONSISTS OF 1, 2, OR 3 LAMPS AND THE TOTAL DISPLAY CAN CONSIST UP TO 7 SUCH GROUPS. VEHICLE DECELERATION IS SENSED AT THREE SEPARATE LEVELS WITHIN THE RANGE 0-1G EACH LEVEL CONTROLLING THE OPERATION OF 1 TO 7 LAMP GROUPS. THE EQUIPMENT MAY BE OPERATED IN EITHER OF TWO MODES, THE LAMPS CAN BE LIT DURING THE DECELERATION PERIOD ONLY OR REMAIN LIT UNTIL THE VEHICLE THROTTLE IS NEXT OPERATED. VISUAL INDICATION OF THE OPERATION OF THE DISPLAY IS PRESENTED TO THE EXPERIMENTER WITHIN THE VEHICLE AND PROVISION IS MADE FOR PERMANENT RECORDING BY A MULTI-CHANNEL RECORDER. THE EQUIPMENT CAN BE USED ON VEHICLES OF ANY LENGTH AND, BEING ELECTRICALLY ISOLATED, IS INDEPENDENT OF VEHICLE CHASSIS POLARITY. /HSL/
