摘要： A system and method for providing a fuel dispenser with radio frequency customer identification capabilities. The system and method determines whether a transponder containing customer identification data is within range of a dispenser, the dispenser requiring activation by the customer to initiate a transaction and including a reader associated therewith for emitting radio frequency signals within the dispenser range, and for receiving customer identification data from the transponder responsive to the emitted radio frequency signals received by the transponder. When the transponder is within range of the dispenser, an in-range indication is provided to the customer. A determination is made whether the dispenser has been activated by the customer following a determination that the transponder is within the dispenser range. Upon activation of the dispenser following the determination that the transponder is within the dispenser range, the customer identification data received by the reader is associated with a transaction at the activated dispenser, whereupon the transaction at the activated dispenser is permitted and charged to the customer according to the customer identification data. The system easily retrofits onto an existing, conventional fuel dispenser.

摘要： A real-time location system for identifying and locating tagged items. The system may include an identification protocol that tracks in-network transponders and assigns dynamic in-network identification numbers to in-network transponders. The system includes a locator function that employs time-of-arrival analysis. Rather than attempt to synchronize the time base at each reader, the system and process eliminate the need to sync the readers and also eliminate the impact of differential receive delays in the respective readers. Both the transponder and a master reader transmit locate signals, which are measured at slave readers. The system relies on differences in time-of-arrival of the two signals at the respective slave readers to determine the likely location of the transponder.

摘要： The invention is an improved method and apparatus for synchronizing wireless communications utilizing a master source (10) for a transmitting a synchronizing pulse to multiple reader modules (20 and 28) each of which has an internal crystal oscillator (22 and 30). The synchronizing pulse periodically resets the interrogation cycle, the power burst and receive cycle, for all of the reader modules (20 and 28). Between pulses, the internal crystal oscillator (22 and 30) is used to run interrogation cycles, and thus functions as a "flywheel" to absorb fluctuations in the synchronizing pulse such as when a particular synchronizing pulse is missed.
