Abstract: Power tools with conductive couplings used with active injury mitigation technology are disclosed. Systems and methods to detect degradation or failure of a conductive coupling in an AIM-enabled power tool are disclosed. Systems and methods to detect impedance of a conductive coupling in an AIM-enabled power tool are disclosed, along with systems and methods to disable such power tool in the event that the detected impedance falls outside predetermined thresholds.

Abstract: Power saws and features for power saws are disclosed. Various features are particularly relevant to jobsite or benchtop table saws. Such features include a frame or support structure with panels and shaped or bent tubes, a trunnion formed from a shaped tube, a tilt mechanism, an elevation mechanism, a retraction mechanism, an arbor block retention mechanism, an insert, a fence, dust collection, shrouding, and a fence stop.

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 miter gauge with discrete indices is disclosed. The indices allow a user to make precise, accurate adjustments to the miter angle of the miter gauge. The miter gauge may include a plurality of sets of indices with discrete steps of different amounts. The miter gauge may include a drive to adjust the miter angle. The drive may include a gear. A reversible miter fence is also disclosed. The miter fence may optionally be used with the miter gauge to provide a larger workpiece support surface. A flip stop mechanism is also disclosed. The flip stop mechanism may optionally be used with the miter fence to provide a reference surface for positioning a workpiece.

Abstract: Fast-acting and low-inertia actuators useable in various applications where a high force must be applied very quickly are disclosed. Power tools with detection systems configured to detect a dangerous condition between a person and a cutting tool are disclosed. In power tools, for example in a woodworking machine, a fast-acting and low-inertial actuator as disclosed herein can be used to retract a blade upon detection of a dangerous condition by a detection system. The actuator includes a charge of pressurized fluid and one or more electromagnets to selectively retain or release the pressurized fluid.

Abstract: Control systems for power tools such as table saws, miter saws, band saws, hand-held circular saws, jointers, shapers, routers, up-cut saws and other machinery are disclosed. The control systems are particularly relevant to power tools equipped with active injury mitigation technology, and to a set, collection, family, series, group or suite of different types of power tools.

Abstract: Control systems to control the operation of a power tool are disclosed. The disclosed control systems are particularly, but not exclusively, applicable to power tools with active injury mitigation technology, and to table saws with active injury mitigation technology, such as jobsite and benchtop table saws. The improved systems, for example, control the supply of power to a motor, enhance reliability, provide redundant safety features, and help to prevent the motor from starting unexpectedly.

Abstract: Inserts for use in table saws are disclosed. One embodiment may include a mechanism to lock mechanically and affirmatively the insert in a blade opening in a table saw. The mechanism is designed so that a user can install and remove the insert without tools. The mechanism also can be designed so that the front of the insert pops up above the table when released from its locked position. The mechanism can be further designed so that the insert can be unlocked or released by a user pressing a button or tab.

Abstract: Inserts for table saws are disclosed. The table inserts are equipped with a toolless locking mechanism that mechanically holds the insert in place and which allows for the installation and removal of the insert without the use of tools. The locking mechanism is easy to lock and unlock and yet robust enough to hold a zero-clearance insert in place.

The blade guard may be part of a dust collection system and may be connected to a vacuum system by a conduit such as a flexible hose.
