Safety device for preventing delivery of fuel to a motor vehicle with a running engine
First Claim
1. In combination, a fuel pump, hose and nozzle and a safety device for a fuel outlet to prevent the delivery of highly combustible fuel to a motor vehicle with a running engine located adjacent to the fuel pump, comprising:
- a sound sensor disposed in or on the ground in front of the fuel pump and including a microphone directed upwardly to sense a sound of a running engine;
a temperature sensor disposed in or on the ground and directed upwardly to sense a temperature of an engine of a motor vehicle parked in front of the fuel pump;
a RF radiation detector adjacent the fuel pump for sensing radiation from spark plugs of a running engine in front of said pump and wherein the RF detector is a short wave radio tuned to 18 MHz;
a control unit, a data analyzer and recognizer operatively connected to the control unit, wherein the data analyzer and recognizer are operatively connected to each of the sensors and detectors for aggregating data from each of the sensors/detectors for communicating a signal to the control unit for allowing or inhibiting operation of the fuel pump depending on whether an adjacent engine is running or stopped; and
an LCD screen and loud speaker for advising a motor vehicle operator to turn off an engine of a motor vehicle in order to refuel the vehicle when the analyzer and recognizer determines a running engine state.

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.
