Claim 17:
18. The computer program product of claim 17, wherein determining that the machine in the de-energized state has rotated in a direction reverse to the reference direction includes:
detecting, for the first time segment of the at least one waveform, a first phase sequence of the power indicia; and
detecting, for the second time segment of the at least one waveform, a second phase sequence of the power indicia;
wherein comparing the first and second time segments of the waveform includes 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.
