Abstract: 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.

Abstract: Machines with safety systems are disclosed. The machine may take the form of woodworking machines including table saws, band saws, miter saws, hand-held circular saws, pneumatic chop saws, radial-arm saws, jointers, planars, routers and shapers. The machines may include an operative structure configured to perform a task, where the operative structure includes a cutting tool adapted to move in at least one motion, and a safety system adapted to detect the occurrence of an unsafe condition between a person and the cutting tool and for mitigating the unsafe condition. The safety system may include a detection subsystem and a reaction subsystem.

Abstract: An automatic main distributing frame, which can easily maintain the size accuracy required to insert into a through hole of the conductive pin is provided. The main distributing frame includes a frame body, plural matrix switch boards accommodated in the frame body, each having matrix switch sections and input/output connectors on a rear section, a back wire board provided on a rear section of the frame body, having connectors connected to the input/output connectors on each rear section of the plural matrix switch boards, and plural robots, each positioned between a pair of two matrix switch board sections of the plural matrix switch boards, each having a hand section for inserting connection pins to the matrix switch sections of the two matrix switch boards.
