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. The machine may also include a bypass or override mode where in an injury mitigation system is disabled for certain cuts.

The present disclosure generally relates to a method for performing industrial automation control may include detecting, via a sensor system, positions and/or motions of a human in an industrial automation system, determining at least one derivative value from the detected positions and/or motions, and determining a possible automation command and an undesirable condition based upon the detected positions and/or motions and the at least one derivative value. The method may then include implementing a control and/or notification action based upon the determined possible automation command and the undesired condition.

There is provided an emergency braking apparatus for stopping travel of the blade of an electrically powered saw of the type incorporating a cutting table through which the blade of the saw passes during a cutting operation. The apparatus comprises a braking jaw and a movable jaw spaced apart from the braking jaw for reception of the blade of the saw between the braking jaw and the movable jaw. The apparatus also comprises a driver for driving the movable jaw from a retracted position into contact with a side face of the blade to force an opposite side the blade against the braking jaw and thereby clamp the blade between the braking jaw and the movable jaw, a pressure chamber for holding a fluid at a predetermined pressure, and an actuator operable in response to an emergency braking signal to release the pressurised fluid in the pressure chamber to drive the driver against the movable jaw whereby the movable jaw is driven into contact with the side face of the blade.

A work device includes a work device body and a contact preventer. The work device body includes a linear motion unit having three degrees of freedom and a rotary unit having three degrees of freedom. An end effector is mounted on an output portion of the rotary unit. The contact preventer separates a working region in which the work device body is installed, from a non-working region outside the working region. The contact preventer includes: an entry allowing portion allowing an object to enter the working region therethrough; and an entry allowing portion entry detection sensor configured to detect entry of an object into the working region through the entry allowing portions.
