| description | A power tool movement monitor system including a first accelerometer operatively configured to sense movement along a first axis of a power tool and a first high pass filter operatively connected to the output of the first accelerometer. The first high pass filter has an output and a cutoff frequency corresponding to a predetermined acceleration limit capable of being output by the first accelerometer. The power tool movement system further includes a logic circuit operatively configured to generate a warning signal when the first high pass filter outputs a signal having a frequency equaling or exceeding the cutoff frequency of the first high pass filter. |
