Abstract
An electric can opener comprises a motor, a controller, and a signal-detecting element monitoring at least one of (i) an audio signal and (ii) a motion-type signal during operation of the can opener. The controller determines a baseline signal value, calculates a threshold signal value and compares the monitored signal value to the calculated threshold value. The controller stops operation of the can opener if the detected signal is outside the threshold from the baseline.
