    摘要： Improved methods to detect when a human body contacts a predetermined portion of a machine are disclosed. The methods distinguish contact with a person from contact with other materials. The methods are particularly applicable in woodworking equipment such as table saws to distinguish contact between a person and the blade of the saw from contact between the blade and wet or green wood.

    摘要： Cutting machines with high-speed safety systems, and actuators used in high-speed safety systems, are disclosed. The cutting machines may include a detection system adapted to detect a dangerous condition between a cutting tool and a person. A reaction system performs a specified action, such as stopping the cutting tool, upon detection of the dangerous condition. An actuator may be used to trigger the reaction system to perform the specified action.

    摘要： Table saw blade guards with lateral guards, blade guard assemblies, and table saws including the same. The blade guards include at least one lateral guard that restricts access to a lateral side, or face, of the saw's blade, and may include a top guard. The lateral guard is selectively moved, such as responsive to engagement by a workpiece, between a non-cutting position and a plurality of cutting positions. In some embodiments, the lateral guard is a collapsing lateral guard that has a reduced perimetrical area and/or reduced vertical dimension relative to the saw's work surface when in a cutting position compared to the non-cutting position. In some embodiments, the lateral guard collapses toward the top guard when moved from its non-cutting position to a cutting position. In some embodiments, the lateral guard does not, or does not appreciably, project above the top guard even when in its maximum cutting position.
