Abstract: A controlled fuel distribution system and method for use in a vehicle fuel filling facility, including at least one fuel pump having a nozzle and at least one nozzle-mounted transceiver for receiving information from a vehicle prior to discharge of fuel thereinto and communicating with an authorization subsystem located at the vehicle fuel filling facility, and a fuel flow driven transceiver power generator operated by fuel pumped by the at least one fuel pump and passing through the nozzle for powering the at least one nozzle-mounted transceiver.

Abstract: A system for detecting and reporting irregularities in fuel efficiency data vehicles. The system includes a database and a data processing mechanism. The data base includes fueling event data, vehicle identification data and data pertaining to an operational parameter. The data processing mechanism calculates a vehicle specific fuel efficiency statistic, compares the calculated statistic to a previous statistic employing a predetermined rule to determine if the newly calculated statistic is unreliable and prepares a report which indicates unreliable fuel efficiency statistics by vehicle. Further disclosed is a method for generating reports which indicate unreliable fuel efficiency statistics by vehicle.
