Automatic fuel dispensing control system

Claim 1

An automatic fuel control dispensing system for vehicles comprising: a fuel control transmitter for mounting on a vehicle and operable on long wavelength at low power radio frequency, said transmitter comprising a transmitting antenna which radiates modulated RF signals to a fuel control receiver, a programmable means for storing multiple digital input data comprising a meassage, and means including a carrier oscillator for selectively transmitting signals comprising said message through said transmitting antenna to the fueling receiver, said message comprising vehicle identification and fuel requirement needs of the vehicle on which said transmitter is mounted, said signals of said transmitter being modulated in a digital manner in a continuously repeated message, a transmitter programmer for storing in said programmable means at least a part of said message comprising a vehicle identification code, a fuel type code, a fuel limit code and a user code, a fuel control receiver for mounting on a housing of a fuel dispensing mechanism, said receiver comprising an antenna for receiving signals comprising a message transmitted by said transmitter, a demodulator for extracting the encoded digital information in said message, means for storing the data content of the message received, means for checking the message against stored information and rejecting from storage all messages received having an incorrect user's code and providing a visual indication of this condition, means for activating a fuel dispenser mechanism, and means for sequentially activating a recording device which monitors the operation of the previously actuated fuel dispenser mechanism.
