Abstract

A portable data probe includes a portable housing, an optical transceiver circuit and a wireless communication circuit. The optical transceiver circuit is disposed substantially within the portable housing, but is also configured to be in optical communication with an exterior of the portable housing. The optical transceiver circuit is operable to convert between electrical signals and corresponding optical signals. The wireless communication circuit is also disposed substantially within the housing, and is operably coupled to the optical transceiver circuit. The wireless communication circuit is operable to communicate wireless signals to a remote wireless circuit.

Claims

1. A method, comprising:

a) communicating optical signals from a utility meter to an optical communication circuit of a probe, the optical signals including metering information in the form of digital data generated at least in part by a digital processor within the utility meter;

b) communicating the metering information from a wireless communication circuit of the probe to a wireless communication circuit of a computing device;

c) storing the metering information in the computing device; and

prior to step a), establishing a wireless communication link between the computing device and the wireless communication circuit, wherein establishing the wireless communication link further comprises transmitting from the computing device a wireless signal having information corresponding to the wireless communication circuit, the wireless communication circuit configured to establish the wireless communication link only after receiving the wireless signal having the information.

2. The method of claim 1, wherein the information corresponding to the wireless communication circuit is unique to the wireless communication circuit.

3. The method of claim 1, wherein step a) further comprises:

communicating the optical signals from the utility meter though an interface of a housing of the probe.

4. The method of claim 1, wherein step a) further comprises:

communicating the optical signals from the utility meter though a lens of a housing of the probe.

5. The method of claim 1, wherein step a) further comprises:

communicating the optical signals from the utility meter though a sized opening of a housing of the probe.

6. The method of claim 1, further comprising a step of retaining the probe against the utility meter at least in part using a magnet.

7. The method of claim 1, further comprising providing power to the wireless communication circuit using a battery.

8. The method of claim 1, further comprising a step of using level conversion circuitry disposed between the wireless communication circuit and the optical communication circuit, the level conversion circuitry operable to convert a first maximum level digital signal to a second maximum level digital signal.

9. The method of claim 8, wherein the second maximum level digital signal is a TTL standard signal.

10. The method of claim 1, wherein step b) further comprises communicating the metering information to the computing device using a wireless modem integrated circuit.

11. The method of claim 10, wherein step b) further comprises communicating the metering information using Bluetooth standard wireless signals.

12. The method of claim 1, further comprising:

d) communicating configuration information from the wireless communication circuit of the computing device to the wireless communication circuit of the probe; and

e) communicating further optical signals to the utility meter from the optical communication circuit of the probe, the further optical signals including the configuration information.

13. A method, comprising:

a) communicating optical signals from a utility meter to an optical communication circuit of a probe, the optical signals including metering information in the form of digital data generated at least in part by a digital processor within the utility meter;

b) communicating the metering information from a wireless communication circuit of the probe to a wireless communication circuit of a computing device;

c) storing the metering information in the computing device;

d) using level conversion circuitry disposed between the wireless communication circuit and the optical communication circuit, the level conversion circuitry operable to convert a first maximum level digital signal to a second maximum level digital signal;

wherein step a) comprises receiving the optical signals using an optical detector device operably coupled to a bias voltage source, the bias voltage source having a voltage level exceeding a maximum level of the second maximum level digital signal.
