    摘要： A traffic control system for regulating the movement of traffic at an intersection, including magnetic sensors at the entrance and exit ends of each lane leaving said intersection for producing vehicle count signals for each vehicle entering and leaving the lane, and traffic lights at said intersection having controllers for varying the cycles, offsets and splits thereof for regulating flow of traffic across the intersection into each of said lanes. Counters respond to the count signals for determining the number of vehicles in each selected street block and logic means respond to the counters for determining the direction of the greatest traffic flow and applying control signals to said traffic signal light controllers to control the same in response to the sensed traffic conditions.

    摘要： AN ELECTRONIC SCORING SYSTEM FOR SCORING VEHICLES IN A PLURAL LAP RACE ON A RACE TRACK INCLUDING A TELEMETRY TRANSMITTER ON EACH VEHICLE TRANSMITTING DISTINCTIVE SIGNALS IDENTIFYING THE VEHICLE, TELEMETRY RECEIVERS FOR RECEIVING SIGNALS FROM THE TRANSMITTERS WHEN THE VEHICLES ARE IN A SELECTED RECEPTION RANGE ZONE NEAR THE FINISH LINE, VEHICLE COUNTERS ACTIVATED BY THE RESPECTIVE RECEIVERS FOR REGISTERING THE LAPS COMPLETED BY EACH VEHICLE, A LEAD LAP COUNTER FOR REGISTERING THE IDENTITY OF THE LEADING VEHICLE AND THE LAPS COMPLETED, LOGIC CIRCUITRY FOR STORING CERTAIN OF THIS REGISTERED INFORMATION, AND PRINTERS FOR PRODUCING A FIRST PRINTOUT AFTER EACH LAP OF THE VEHICLE NUMBER BY POLE POSITION, THE LAPS COMPLETED AND ELAPSED TIME, AND A SECOND PRINTOUT AFTER EVERY TENTH LAP OF THE ORDER OF THE VEHICLES.
