Abstract
A power tool including a motor configured to produce an output, and a sensor configured to measure an acceleration of the power tool along at least one of three spatial axes and generate an output signal related to the acceleration. The power tool further including a controller configured to receive the output signal related to the acceleration of the power tool from the sensor, compare the acceleration of the power tool to a free-fall acceleration threshold, initiate a timer when the acceleration of the power tool corresponds to the free-fall acceleration threshold, compare the timer to a free-fall timer threshold, and stop the motor from producing the output when the timer is greater than or equal to the free-fall timer threshold.
