    Abstract: 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.

    Abstract: A rotating power connection for connecting an electrical supply power cable to an electric welding torch body is provided. In the rotating power connection, the mechanical load is carried by steel bearings, and the electric load is carried by multi-contact, spring loaded fins made out of highly conductive materials or coatings. In some examples, a rotating power connector is affixed to a torch before the power connection to a wire feeder. The rotating power connector advantageously allows for rotation of the welding torch relative to the unicable while providing continual electrical connection at the high current levels employed in welding applications.

    Abstract: A bearing isolator and explosion-proof current diverting device may be configured to dissipate an electrical charge from a rotating piece of equipment to ground, such as from a motor shaft to a motor housing. One aspect of an explosion-proof current diverter ring may include a stator that may be mounted to the equipment housing and a rotor that may be mounted to a shaft. The rotor may rotate with the shaft. A conductive assembly may be positioned in a radial bore formed in the stator such that the conductive assembly contacts the rotor to conduct electricity from the shaft to the housing through the explosion-proof current diverting device. The explosion-proof current diverting device may be configured to define a flame path to achieve various explosion-proof certifications.
