Abstract

A system and method for synchronizing a parking meter clock is provided. The system includes a parking meter having a clock and an antenna coupled to the parking meter for receiving a wireless broadcast data including a time data. The parking meter further provided with a receiver and an interface. The receiver communicates with the antenna to demodulate the wireless broadcast data received by the antenna and the interface communicates with the receiver to communicate the wireless broadcast data to synchronize the clock on the parking meter. A method of synchronizing a clock on one or more parking meters is also provided that includes receiving a wireless broadcast data including a time-of-day data. The method further includes updating the clock on the parking meter based on the wirelessly broadcast data. In one aspect, the time-of-day data is based on an atomic clock.

Claims

1. A parking meter, comprising:

a processor to process parking related information;

a clock in communication with the processor;

an antenna coupled to the parking meter for receiving a wireless broadcast data;

a receiver communicating with the antenna to demodulate the wireless broadcast data received by the antenna; and

an interface communicating with the receiver to communicate the wireless broadcast data.

2. The parking meter of claim 1, wherein the antenna is further defined as a ferrite antenna.

3. The parking meter of claim 1, wherein the parking meter is further provided with a printed circuit board coupled to the parking meter and wherein the antenna is further defined as a trace on the printed circuit board.

4. The parking meter of claim 1, wherein the wireless broadcast data is further defined as an AM signal and the receiver is further defined an integrated circuit for receiving the AM signal.

5. The parking meter of claim 1, wherein the wireless broadcast data includes a time data related to a current time-of-day.

6. The parking meter of claim 5, wherein the processor is operative to synchronize the clock based on the time data in response to receiving the wireless broadcast data.

7. A method of synchronizing a clock on a parking meter, comprising:

receiving a wirelessly broadcast data that includes a time-of-day data; and

updating the clock on the parking meter based on the wirelessly broadcast data.

8. The method of claim 7, wherein the time-of-day data is based on an atomic clock.

9. The method of claim 7, wherein the time-of-day data is based on a time reference generated by a television signal.

10. The method of claim 7, wherein the wirelessly broadcast data is further defined as a wireless internet connection and wherein the time-of-day data is further defined as a time reference based on a standard time measurement device.

11. The method of claim 10, wherein the standard time measurement device is an atomic clock.

12. A method of synchronizing time circuits on a plurality of parking meters, comprising:

broadcasting a time signal including a time-of-day data;

receiving the time signal by a plurality of parking meters; and

synchronizing a clock on at least one of the plurality of parking meters based on the time signal.

13. The method of claim 12, wherein the time-of-day data is based on an atomic clock.

14. The method of claim 12, wherein the time-of-day data is based on a time reference generated by a television signal.
