摘要:
A power tool used to perform a coping cut including a main housing, a motor disposed within the main housing, a drive shaft driven by the motor about a rotational axis, a handle extending from the main housing, and an abrasive disc coupled to and driven by the drive shaft about the rotational axis. The motor is an outer rotor brushless direct current motor capable of rotating at 4,000 surface feet per minute at 1.5 inch-pounds of torque.

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 man 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.

The invention relates to a method for operating a panel-processing installation, wherein a monitoring region of the panel-processing installation is monitored by means of at least a first sensing device. According to the invention a quantity that is relevant to the safety of a person located in the monitoring region and/or to the safe operation of the panel-processing installation is determined (82) by means of the first sensing device, the existence of a situation is inferred (120) from the determined quantity, and an action occurs (146) in dependence on the situation.

Disclosed is an apparatus for mechanically splitting materials, including a body with a cutting element arranged relative thereto. The cutting element includes at least one cutting surface oriented vertically. The splitting apparatus includes the cutting element applying an upward pressure against the material which is split when a separate downward force is applied to the material. The body of the splitting apparatus also includes a safety element to protect the user from the cutting element; an elongate supporting element to distance the safety element from either or both the cutting element and a surface on which the splitting apparatus is used; a stabilizing element to stabilize the splitting apparatus relative to a surface on which the splitting apparatus is used; and optionally a deflecting element to deflect split materials away from the cutting element and container element to contain therewithin split materials produced during the splitting.
