Shock detection in a utility meter having reporting capability

1. A method, comprising:

detecting an impact force on a housing of an electricity meter using a force detector within a housing of the electricity meter;

comparing the detected impact force to an impact force threshold value using a control circuit within the housing of the electricity meter;

storing within the electricity meter, when said meter is disconnected from utility power lines, an indication of a detected impact force on the electricity meter in response to the detected impact force exceeding the impact force threshold value; and

providing a visible indication of the detected impact force.

2. The method of claim 1 , wherein the force detector comprises a mechanical shock detector.

3. The method of claim 2 , wherein the visible indication comprises releasing a chemical held in suspension.

4. The method of claim 1 , wherein the force detector includes an accelerometer.

5. The method of claim 4 , wherein the visible indication comprises displaying an indication of the detected impact force on a meter display.

6. The method of claim 1 , further comprising storing an indication of time and date corresponding to the occurrence of the detected impact force.

7. An arrangement for use in a utility meter, comprising:

an accelerometer configured to detect impact force on a utility meter housing;

a processing circuit operably coupled to receive information representative of detected shock events from the accelerometer, and configured to store information regarding detected shock events in a non-volatile memory; and

a source of power independent of a main meter power supply operably connected to the processing circuit,

wherein the accelerometer includes control circuitry and a serial interface, the control circuitry configured to cooperate with the processing circuit to store detected force information if the detected force exceeds a predetermined impact force threshold value.

8. The arrangement of claim 7 , wherein the accelerometer is configured to store detected force information in volatile memory, and wherein the processing circuit is configured to receive the stored detected force information from the volatile memory and store the detected force information in non-volatile memory.

9. The arrangement of claim 7 , wherein the control circuitry is operably coupled to the accelerometer via a serial communication link.
