    Abstract: Table saws are disclosed. The table saws can include a blade, an arbor, an arbor block, an elevation carriage, and a latch that connects the arbor block and the elevation carriage. The arbor block can have a first position in which the latch connects the arbor block and the elevation carriage, and a second position in which the latch does not connect the arbor block and the elevation carriage. The arbor block can pivot from the first position to the second position upon the occurrence of a retraction force. The table saw can include an actuator to cause the occurrence of the retraction force, and detection electronics to detect contact between the blade and a person. Woodworking machines with detection and reaction systems are also disclosed. A reaction system can include an explosive that causes retraction of a cutting tool.

    Abstract: A safety control system for power operated equipment which ensures operator safety by immediately disconnecting the power drive from a power driven rotating member, such as a toothed feed shaft of a meat skinning machine or a moving blade of a band saw, and then positively stops and then reverses the direction of movement of the rotating member, upon a metal conductive glove worn by the operator, contacting the blade or toothed shaft. The operator's glove is electrically connected to a safety mechanism and upon the glove completing a circuit upon contact with the rotating member or equipment immediately disconnects the power drive from the rotating member by actuating a clutch or tensioning cylinder. A trigger mechanism then is actuated and permits a positive stopping element to engage and stop the moving element. A power actuated plunger then is actuated and moves the stopping element in an opposite direction to reverse the direction of the rotating member in an incremental step to further reduce the possibility of injury to the operator. A moisture impervious dielectric plastic glove preferably is worn by the operator to prevent the moisture in the meat from conducting current between the metal glove and machine until the plastic glove is cut and contact made with the metal glove. A switch requires manual actuation to connect the power drive to the rotatable member. The metal gloves are connected to the safety switch by electrodes secured to the metal gloves.

    Abstract translation: 一种用于动力操作设备的安全控制系统，其通过立即将动力驱动器与动力驱动的旋转构件（例如肉皮机的齿形进给轴或带锯的动叶片）断开连接并确保操作者的安全，然后积极地停止 然后在操作者佩戴的金属导电手套上接触叶片或齿形轴，使旋转构件的运动方向反转。 操作者的手套电气连接到安全机构，并且当与旋转构件或设备接触时手套完成电路时，通过致动离合器或张紧缸立即将动力驱动器与旋转构件断开。 然后触发机构被致动并且允许正止动元件接合和停止移动元件。 然后，动力驱动的柱塞被致动并沿相反的方向移动止动元件，以在增量步骤中反转旋转构件的方向，以进一步降低对操作者的伤害的可能性。 操作者最好佩戴不透水的介电塑料手套，以防止肉中的水分在金属手套和机器之间传导电流，直到塑料手套被切割并与金属手套接触。 开关需要手动致动以将动力驱动器连接到可旋转构件。 金属手套通过固定在金属手套上的电极与安全开关连接。

    Abstract: A saw with a monitoring and safety system that utilizes vision and sensors designed to provide user feedback on safety and training. The saw having a wheel formed of an anodized main body with a non-anodized surface extending along the circumference of the groove of the wheel. The saw having low inertial energy design to stop the blade without mechanically grabbing the blade assuring multiple points of safety detection and triggering. The saw having an automatic guard to protect the user from slipping and hitting the blade even when the saw is not running. The saw being connected to a cloud based system that enables a safer ecosystem and cross statistic sharing of safety parameters.

    Abstract: A safety apparatus for protecting an operator of an electrically powered saw from the blade during operation, the saw being of the type including a cutting table through which the blade passes, comprising: an image processing arrangement operable to sense, within a predefined three-dimensional sensing zone, the presence of a glove worn by the operator which has a colour distinguishable by the image sensor from the colour of an object being cut by the blade, the three-dimensional sensing zone being located in a cutting path of the blade; and an electronic controller communicable with the image sensor and operable to control an arresting mechanism to arrest movement of the blade responsive to the coloured glove being detected within the three-dimensional sensing zone.
