Fuel dispenser time synchronization and geotracking
First Claim
1. A method for obtaining accurate time information at a fuel dispenser, said method comprising the steps of:
- providing a synchronization module in electronic communication with a control system of a fuel dispenser, said control system in operative communication with hydraulics of said fuel dispenser and comprising a memory, said control system further comprising an operating system which maintains a first time;
receiving at said synchronization module a carrier wave modulated with synchronization information;
generating at said synchronization module information representative of a second time; and
transmitting said information representative of said second time to said control system.

Abstract
A fuel dispenser has internal fuel flow piping, a flow meter located along the internal fuel flow piping, and a displacement sensor operatively connected to the flow meter to generate information representative of an amount of fuel passing through the flow meter. The fuel dispenser also has a control system comprising a memory. In embodiments, however, the control system does not comprise a real-time clock. The fuel dispenser also comprises a synchronization module in electronic communication with the control system. The synchronization module comprises at least one antenna configured to receive a carrier wave modulated with synchronization information. Methods for obtaining accurate time information at the fuel dispenser are also disclosed.
