Classification: CPC H | IPC H

Claim 2:
3. The computer system of claim 2, wherein the computer system determining that the machine in the de-energized state has rotated in a direction reverse to the reference direction includes:
detecting by the computer system, for the first time segment of the waveform, a first phase sequence of the power indicia; and
detecting by the computer system, for the second time segment of the waveform, a second phase sequence of the power indicia;
wherein the computer system comparing the first and second time segments of the waveform includes the computer system comparing the first and second phase sequences of the waveform, and wherein the determining that the machine in the de-energized state has rotated in a direction reverse to the reference direction includes detecting, based on the comparing, that the second phase sequence does not correspond to the first phase sequence.
