Abstract
A method for operating a power tool detects human contact with a non-moving implement of the power tool. The method includes sampling an electrical signal that passes through the non-moving implement, identifying in-phase and quadrature phase components for the sample, identifying a first distance between the components of the sample and a centroid of a cluster of samples corresponding to human contact with the non-moving implement, identifying a second distance between the components of the sample and a second centroid identified for another cluster of samples corresponding to no human contact with the non-moving implement, and identifying human contact with the non-moving implement with reference to the first distance being less than the second distance.
