Реферат: The power tools (10) include a motor (20), and a sensor assembly (100) configured to generate a differential voltage signal (102) that is indicative of a distance between an individual and a cutting tool (60) being less than a threshold distance. The sensor assembly also is configured to produce a sensor assembly output (104) that is based upon the differential voltage signal. The power tools further include an analysis circuit (300) configured to receive the sensor assembly output and to generate a trigger signal (302) responsive to the sensor assembly output being outside a nominal sensor assembly output range. The power tools also include a mechanical reaction mechanism (70) configured to insulate the individual from the cutting tool responsive to receipt of the trigger signal. Method for verifying operation of said sensor assembly.
