Monitored delivery systems

A system for dispensing liquid fuel to vehicles, said system comprising:

• a fuel delivery conduit having a dispensing nozzle;
• an optical data reader carried by said dispensing nozzle;
• optical data providing means for mounting on a vehicle to provide data identifying that said vehicle;
• said vehicle provided with a fuel tank having a tubular entry port for reception of said dispensing nozzle during fuel dispensing, said tubular entry port having an inlet, a longitudinal axis and an inner circumferential surface;
• said optical data providing means comprising an active optical data transmitter disposed on said inner circumferential surface at a position spaced down from said inlet within said tubular entry port;
• a source of vehicle identifying data disposed on said vehicle remote from said tank, and means connecting said source to said active optical data transmitter;
• said active optical data transmitter extending circumferentially of said inner circumferential surface generally perpendicular to said longitudinal axis of said tubular entry port;
• said optical data reader comprising an optical data receiver adapted to receive data optically transmitted by said active optical data transmitter;
• said optical data reader positioned on and extending circumferentially of said dispensing nozzle to receive said optically transmitted data upon longitudinal insertion of said dispensing nozzle into a predetermined safe fuel dispensing position within said tubular entry port, said circumferentially extending disposition of both said active optical data transmitter and said optical data receiver permitting said data receiption at any relative angular orientation of the dispensing nozzle within a range about said longitudinal axis of said tubular entry port.
