A power tool comprising: a cutting assembly having a moving component with a blade wherein a blade guard covers a top portion of the blade; a sensor system proximate to the cutting assembly; the sensor system comprises a capacity sensing chip, and one or more receivers (170; 172; 174; 176; 178; 180; 182); a reaction system operably connected to the cutting assembly; a memory; program instructions stored within the memory; a spatial recognition algorithm stored within the memory; and a processor operably connected to the reaction system, the sensor system, and the memory, the processor configured to execute the program instructions to obtain a respective signal from each of the one or more receivers (170; 172; 174; 176; 178; 180; 182) detect a human profile within a detection zone associated with the cutting assembly, establish a location of the human profile within the detection zone based upon the detection using the spatial recognition algorithm and based upon the respective signals, characterized in that the processor is further configured to execute the program instructions to define a danger zone with respect to the blade and based upon a determined position of the blade, define the danger zone based upon a determined position of a blade guard located about a portion of the blade while the position of the blade guard is being varied, and determine that an unsafe condition exists based upon the established location and the danger zone, and activate the reaction system. a cutting assembly having a moving component with a blade wherein a blade guard covers a top portion of the blade; a sensor system proximate to the cutting assembly; the sensor system comprises a capacity sensing chip, and one or more receivers (170; 172; 174; 176; 178; 180; 182); a reaction system operably connected to the cutting assembly; a memory; program instructions stored within the memory; a spatial recognition algorithm stored within the memory; and a processor operably connected to the reaction system, the sensor system, and the memory, the processor configured to execute the program instructions to obtain a respective signal from each of the one or more receivers (170; 172; 174; 176; 178; 180; 182) detect a human profile within a detection zone associated with the cutting assembly, establish a location of the human profile within the detection zone based upon the detection using the spatial recognition algorithm and based upon the respective signals, characterized in that the processor is further configured to execute the program instructions to define a danger zone with respect to the blade and based upon a determined position of the blade, define the danger zone based upon a determined position of a blade guard located about a portion of the blade while the position of the blade guard is being varied, and determine that an unsafe condition exists based upon the established location and the danger zone, and activate the reaction system. obtain a respective signal from each of the one or more receivers (170; 172; 174; 176; 178; 180; 182) detect a human profile within a detection zone associated with the cutting assembly, establish a location of the human profile within the detection zone based upon the detection using the spatial recognition algorithm and based upon the respective signals, characterized in that the processor is further configured to execute the program instructions to define a danger zone with respect to the blade and based upon a determined position of the blade, define the danger zone based upon a determined position of a blade guard located about a portion of the blade while the position of the blade guard is being varied, and determine that an unsafe condition exists based upon the established location and the danger zone, and activate the reaction system.
