Abstract
A method of determining the angular position of a roll includes: (a) detecting signals generated by an accelerometer attached to an end of a rotating roll; (b) determining whether a signal generated in step (a) has reached a pre-trigger threshold, and repeating step (a) if the signal has not reached the pre-trigger threshold; (c) if the signal is determined in step (b) to have reached the pre-trigger threshold, detecting a subsequent signal generated by the accelerometer; (d) determining whether the signal detected in step (c) has reached a trigger threshold, and repeating step (c) if the signal has not reached the trigger threshold; and (e) if the signal has reached the trigger threshold, establishing the angular position of the roll based on the signal that has reached the trigger threshold.
