A band saw including a frame, at least two, spaced apart, rotatable wheels supported by the frame, a blade looped around the wheels, where rotation of at least one wheel causes the blade to move around the wheels, a detection system adapted to detect a dangerous condition between a person and the blade, and a reaction system configured to engage and stop the blade within 10 milliseconds after detection of the dangerous condition is disclosed. The reaction system may be configured to cut and grip the blade.
1. A band saw comprising: a frame;at least two, spaced apart, rotatable wheels supported by the frame;a blade looped around the wheels, where rotation of at least one wheel causes the blade to move around the wheels;an electronic circuit adapted to detect contact between a person and the blade, wher
1. A band saw comprising: a frame;at least two, spaced apart, rotatable wheels supported by the frame;a blade looped around the wheels, where rotation of at least one wheel causes the blade to move around the wheels;an electronic circuit adapted to detect contact between a person and the blade, where the electronic circuit uses capacitance to detect the contact, and where the electronic circuit generates a signal upon detection of the contact; anda reaction system connected to the electronic circuit to receive the signal, where the reaction system is triggerable by the signal to engage and stop the blade within 10 milliseconds after being triggered, and where the reaction system includes a component moveable from a first position away from the blade to a second position in contact with the blade. 2. The band saw of claim 1, where the electronic circuit imparts an electric charge on the blade through a capacitive coupling. 3. The band saw of claim 2, where the wheels are electrically isolated from the frame. 4. The band saw of claim 2, where the blade is electrically isolated from the frame. 5. The band saw of claim 4, where the capacitive coupling includes a conductive plate positioned adjacent the blade. 6. The band saw of claim 2, further comprising a housing a enclosing the wheels, and where the housing is constructed to minimize any capacitive coupling between the housing and the wheels and/or blade. 7. The band saw of claim 2, further comprising a housing enclosing the wheels, where the housing is made at least partially of a non-conductive material. 8. The band saw of claim 1, where the reaction system also includes an electrically triggerable actuator, where the signal triggers the actuator, and where the actuator, when triggered, causes the component to move from the first position to the second position.
