A safety system for a power miter saw comprises a support member, at least one multidirectional manipulator including a workpiece holder member moveably mounted to the support member for securing a workpiece in place, and a control box. The workpiece holder member includes a presence indicator operatively connected to the control box and configured to detect the physical presence of a saw operator's hand on the at least one multidirectional manipulator when the saw operator's hand engages the presence indicator. The control box is operatively connectable to a trigger switch of the power miter saw so that an electric motor of the power miter saw is activated only when both the presence indicator of the safety system and the trigger switch of the power miter saw are engaged by both hands of an operator of the power miter saw.

The invention relates to a holding device for a test sheet (1), with a receiving arrangement (2) for engagement with the test sheet (1), a handle arrangement (3) connected rigidly to the receiving arrangement (2) for a user (4) for positioning the test sheet (1), and a pushbutton arrangement (5) for producing a switching signal on the basis of an actuation by the user (4).

A perforation device to perforate closed receptacles containing coloring products is provided, and includes a support plane which is configured to support a receptacle to be perforated. The support plane is movable in a substantially vertical direction. The perforation device also includes a perforation member positioned at a determinate height, higher than the support plane, and an actuator to selectively move the support plane toward the perforation member to cause the perforation of the receptacle to be perforated. The actuator includes a lifting mechanism connected to the support plane and drivable by a pedal that cannot be driven by an operator without the operator also driving a safety mechanism at the same time using both hands.

An example material testing system includes: an actuator configured to control an operator-accessible component of the material testing system; and one or more processors configured to: control the actuator based on at least one of an operator command or a material testing process; determine, based on a plurality of inputs, a state of the material testing system from a plurality of predetermined states, the predetermined states comprising one or more unrestricted states and one or more restricted states; when the state of the material testing system is one of the restricted states, enforce a restriction on the actuator; and in response to completion of an action involving controlling the actuator, automatically set the state of the material testing system to one of the restricted states.

Production and work machines are to be able to be more safely operated. Thereto, they can be equipped with a safety device, which comprises a light curtain, a first and a second reflection device, which are each formed for reflecting light of the light curtain, and a first identification element integrated in the first reflection device as well as a second identification element integrated in the second reflection device. Moreover, the safety device comprises a first sensor device and a second sensor device for reading out the identification elements. A control device provides a start signal for the machine only if the first sensor device reads out the first identification information and the second sensor device reads out the second identification information at the same time.

A system and method relating to a slicer system, the slicer system includes a slicer that includes a slider blade, a first motor configured to rotate the slicer blade, an in-feed table configured to hold the product and move, while the product is sliced by the slicer blade; an out-feed table configured to receive a sliced portion of a product, in response to the slicer blade slicing the product, at least one second motor, each of the at least one second motor configured to move the out-feed table in at least one direction; and at least one processor configured to cause the sliced portion of the product to be received on the out-feed table in a predetermined shape by controlling the at least one second motor to move the out-feed table while the slicer is slicing the product.
