Abstract: A method and apparatus is provided for determining if a vehicle with an operating engine is at a particular location, the apparatus comprising: an antenna comprising a continuous wire formed into at least one loop; and a means to determine when the antenna is exposed to an oscillating electromagnetic field having a frequency between about 700 and about 2100 Hz of a strength characteristic of a vehicle's alternator operating in the vicinity of the antenna. In a preferred embodiment of the present invention, the sensor of the present invention further comprises a means to generate a signal when the antenna is exposed to the oscillating electromagnetic field having a frequency between about 700 and about 2100 Hz of a strength characteristic of a vehicle's alternator operating in the vicinity of the antenna, and the signal is used as an input into a logic system that requires that the signal not be generated in order for a refuelling system to refuel a vehicle in the vicinity of the antenna.

Abstract: A method for automated refuelling is provided, the method comprising the steps of: providing the vehicle with a radio frequency transponder effective to communicate information sufficient to establish a position of a fuel inlet on the vehicle; receiving the communicated information at location where the vehicle is to be refuelled when the vehicle is located at the location where the vehicle is to be refuelled; when the vehicle is located at the location where the vehicle is to be refuelled, determining the position and orientation of the vehicle within the location; determining from the position and orientation of the vehicle and the communicated information, an expected location of the fuel inlet; after the vehicle is driven to an automated refuelling apparatus, initiating refuelling by moving a fuel dispenser to adjacent the expected location of the fuel inlet; providing a sensor on the fuel dispenser to determine the location of the fuel inlet relative to the fuel dispenser; repositioning the fuel dispense
