Claim:
1. A sensor arrangement for a table saw comprising: at least one dielectric sensor embedded in a table top of the table saw having a slot opening in which a circular blade is arranged; a deflection plate embedded in the table top, arranged on a side of the at least one dielectric sensor opposite an upper surface of the table top and electrically insulated from the at least one dielectric sensor; and a ground plane positioned on a side of the deflection plate opposite the at least one dielectric sensor and electrically insulated from the at least one dielectric sensor and the deflection plate, wherein the sensor arrangement is configured to generate a first actuation signal based upon predetermined sensed characteristics relating to a portion of a person in a sensed volume, wherein the at least one dielectric sensor and the deflection plate are both embedded in a composite insulation layer, which defines at least in part the upper surface of the table top.
