System and method for identification of contact between a human and a static implement in a power tool
Abstract:
A method of operating a power tool detects human contact with a non-moving implement in the power tool. The method includes generating a series of samples of an electrical signal passing through the non-moving implement, identifying a component for each sample in the series of samples of the electrical signal, identifying a first max−min value corresponding to a first plurality of samples in the series of samples occurring during a first periodic time interval with reference to a difference between a maximum value and a minimum value identified in the components of the first plurality of samples, and identifying human contact with the non-moving implement in response to the first max−min value being greater than a first predetermined threshold.
