A safety system for powered cutting tools includes a miter saw safety device. Embodiments of the miter saw safety device may be positioned on one or both sides of the rotating saw blade and include a pivotable support arm and a support plate that is repositionable relative to the support arm. In some embodiments the support plate is biased toward the guide fence of the miter saw. The device enhances the capabilities of miter saw to make precise cuts safer, faster and easier.

Power tools with conductive couplings used with active injury mitigation technology are disclosed. Conductive couplings are particularly relevant to table saws, hand-held circular saws, track saws, miter saws, and band saws with active injury mitigation technology. Conductive couplings provide a mechanism through which an electrical signal can be coupled or imparted to a blade, and then monitored for changes indicative of human contact with the blade. An exemplary conductive coupling includes a brush that establishes an electrical connection with a moving part of a power tool, and the brush maintains contact with the moving part of the power tool during at least 40 hours of cumulative time when the motor is spinning the arbor and blade without an interruption in the electrical connection sufficient to trigger the reaction system. A conductive coupling may be two-sided compliant. A conductive coupling may connect to a motor shaft to minimize electrical noise.

A safe tablet cutting device includes a container, a cover, a cutter, and a suspension body. A platform in the container provides tablet positioning. First and second positioning elements are configured between a back end of the container and the platform. The cover is hinged to the back end of the container. The suspension body has its back end freely rotatable but confined between the first and second positioning elements when the cover is opened or closed. The suspension body has a slot opening corresponding to the cutter configured on the inside of the cover so that the cutter is properly concealed behind the suspension body and, when the cover is closed, gradually exposed to cut the tablet. The safety and applicability of the tablet cutting device is as such enhanced.
