Safety Device for Preventing Delivery of Fuel to a Motor Vehicle With a Running Engine
First Claim
1. A safety device for a fuel outlet having a fuel pump to prevent the delivery of a highly combustible fuel to a motor vehicle when the motor vehicle'"'"'s engine is running, said safety device comprising a fuel pump and a sound sensor adjacent said fuel pump and adapted to sense the sound of a running engine in a vehicle that is adjacent to the fuel pump, a temperature sensor adapted to check the engine temperature of an adjacent vehicle and an RE radiation detector adjacent said pump detects a running engine, a data analyzer and a control unit for disabling the fuel pump when a running engine detected is positioned in the vicinity of said fuel pump.

Abstract
A safety device for a fuel outlet to prevent delivery of highly combustible fuel to a motor vehicle with a running engine. The safety device comprises a fuel pump for pumping the fuel from an underground tank and into a motor vehicle. The device includes a sound sensor disposed below an area to be occupied by a motor vehicle adjacent to the fuel pump and is adapted to sense the sound of a running engine in an adjacent vehicle and a temperature sensor adapted to detect the engine temperature of an adjacent vehicle. Further, the device or system includes an RF radiation detector adjacent said pump for detecting a running engine, a data analyzer and a control unit for disabling the fuel pump when a running engine is detected in the vicinity of the fuel pump.

9. A safety device for a fuel outlet to prevent the delivery of highly combustible fuel to a motor vehicle with a running engine, said safety device consisting of:
-
a fuel pump, a hose and a nozzle for pumping fuel from an underground tank and into a tank of a motor vehicle; a sound sensor disposed in or on the ground in front of a fuel dispenser and including a sensitive microphone directed upwardly to sense the sound of a running engine; a temperature sensor disposed in or on the ground and directed upwardly to sense the temperature of an engine of a motor vehicle parked in front of a fuel dispensing pump; a RF radiation detector adjacent said pump for sensing radiation from the spark plugs of a running engine in front of said pump and wherein said RF detector is a short wave radio tuned to 18 MHz; a control unit and a data analyzer and recognizer operatively connected to said control unit and said data analyzer and recognizer operatively connected to each of said sensors for allowing or inhibiting operation of said pump depending on whether an adjacent engine is running or stopped; and a relatively large LCD screen and loud speaker for advising a motor vehicle operator to turn off the engine in order to refuel the vehicle when said analyzer and recognizer senses a running engine.
