Embodiment Construction

[0036] For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to the embodiments illustrated in the accompanying drawings and described in the written description below. It should be understood that no limitation of the scope of the present disclosure is thereby intended. It is also to be understood that this disclosure includes any changes and modifications to the illustrated embodiments, and includes further applications of the principles of the disclosure as would normally occur to one skilled in the art to which this disclosure pertains.

[0037] now refer to figure 1, illustrates a power tool in the form of a miter saw assembly 100 . Other types of power tools (such as table saws, slide miter saws, drop saws, compound saws, circular saws, woodworking saws, etc.) are possible. Miter saw assembly 100 includes a base 102 and a turntable 104 rotatable on base 102 . The miter saw assembly 100 also includes a cutting he...

Abstract

In one embodiment, a power tool includes a cutting assembly, a sensor system proximate to the cutting assembly, 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 is configured to execute the program instructions to 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, determine that an unsafe condition exists based upon the established location, and activate the reaction system.

Description

[0001] cross reference [0002] This application claims priority to US Provisional Application No. 61 / 905,726, filed November 18, 2013, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to power tools including a protective system configured to quickly stop movement of a forming device. Background technique [0004] A large number of power tools have been produced to facilitate forming workpieces into desired shapes. One such power tool is a miter saw. Miter saws are a safety hazard because the blades of miter saws are often very sharp and move at a high rate. Consequently, serious injuries such as amputated digits and deep lacerations can occur almost instantaneously. In response to the dangers inherent in exposed saw blades moving at high speeds, a number of different safety systems have been developed for miter saws. One such safety system is a saw blade guard. The blade guard is movable to enclose the ...
