An actuator assembly for a power tool includes an actuator with a permanent magnet. The actuator is moveable between a first position for a first mode of operation, and a second position for a second mode of operation. A first positioning member is adjacent the first position composed of a ferromagnetic material to attract the permanent magnet. A second positioning member is adjacent the second position and composed of a ferromagnetic material to attract the permanent magnet. An electromagnet may be energized to move the actuator between the first position and the second position. When the electromagnet is not energized and the actuator is in the first position, the actuator is retained in the first position. When the electromagnet is not energized and the actuator is in the second position, the actuator is retained in the second position. When the electromagnet is energized, the actuator moves between the first and second positions.

Electromagnetic actuator for power tool

A position tracking system has a laser transmitter, a control tracker and a layout indicator. The laser transmitter has a laser for emitting a laser beam, a controller controlling the laser, and a motor for rotating the emitted laser beam. The control tracker has a housing, at least two photo diodes disposed on the housing, and a laser assembly for generating a beam to be projected unto a surface. The layout indicator has a housing, and at least two photo diodes disposed on the housing. A network server communicates with at least one of the laser transmitter, the control tracker and the layout indicator.

Positional tracking system and method

A power tool includes a housing, a motor disposed in the housing, an output spindle configured to be driven by the motor, an input switch, and a controller configured to control power being delivered to the motor. The controller is operable in one of: (a) a normal mode where the controller causes continuous electric power to be delivered to the motor during actuation of the input switch in a first range of positions; and (b) a feathering mode where the controller causes discontinuous electric power to be delivered to the motor during actuation of the input switch in a second range of positions that is different from the first range of positions motor to simulate feathering the input switch.

A powered tool follower assembly can include a solenoid plunger that is movable longitudinally in a direction aligned with a drive axis in response to energization of the solenoid and a biasing mechanism with a spring axis extending transversely to the drive axis. A lever arm can extend between the plunger and the biasing member and couple the plunger to the biasing mechanism. A pinch roller can be disposed between the lever arm and the driver. Energization of the solenoid can move the plunger longitudinally, causing relative movement between the lever arm and the drive wheel that forces the pinch roller into engagement with the driver and transfers a biasing force from the compression spring through the lever arm and pinch roller to the driver to pinch the driver between the pinch roller and the flywheel and drive the driver along the driver axis.

Powered hand-held fastening tool

A powered hand-held fastening tool includes a housing defining a handle, a frame, a motor-driven flywheel journaled to the frame, and an elongated driver that is selectively coupled to the flywheel to drive a fastener into a workpiece. The flywheel and driver have complementary sloped surfaces that mesh with each other to transmit energy from the flywheel to the driver to accelerate the driver along the driver axis. A follower assembly for selectively coupling the driver to the flywheel includes a solenoid actuator.

A power tool having an integrated control system includes a workpiece supporting surface, a cutting instrument extendable above the workpiece supporting surface, a guard assembly securable above the workpiece supporting surface for covering at least a portion of the cutting instrument, a motor coupled with the cutting instrument, and a power switch operable for starting the motor for driving the cutting instrument. The power tool includes a control system in communication with the guard assembly for determining if the guard assembly is installed. Before the motor is started, the control system automatically disables the motor if it determines that the guard assembly is not installed. The control system includes a bypass switch for enabling starting of the motor when the guard assembly is not installed.

A powered hand-held fastening tool includes a housing defining a handle, a frame, a motor-driven flywheel journaled to the frame, and an elongated driver that is selectively coupled to the flywheel to drive a fastener into a workpiece. A follower assembly for selectively coupling the driver to the flywheel includes a solenoid actuator, a biasing mechanism, a lever arm connected between the solenoid actuator and the biasing mechanism, and an intermediate member having journaled thereto a pivot roller and a pinch roller. Upon energization of the solenoid the lever arm is moved in a direction parallel to the drive axis, thereby applying a force on the pivot roller perpendicular to the drive axis, causing the pinch roller to press the driver against the flywheel and initiate the drive stroke. The intermediate member pivots about the pivot roller to release the pressure on driver upon completion of the drive stroke.

A power tool system includes a power tool, a power tool battery pack and a battery pack charger. The power tool battery pack is separable from and attachable to the power tool, and electrically connectable to the power tool electrical terminals when attached to the power tool. The power tool battery pack has at least one battery cell, a receiver coil, and a control circuit for controlling the amount of power that is provided to the at least one battery cell. The battery pack charger has at least one transmitter coil for generating a magnetic field which induces a voltage in the receiver coil, and a control circuit for controlling the amount of power that is provided to the transmitter coil.

A router includes a housing and a motor assembly disposed within the housing. The motor assembly includes a driven shaft having a cavity on a first end of the driven shaft. The router includes a collet that is configured to mate into the cavity of the driven shaft with the collet being configured to grip a shank of a router bit. The router includes a gear mechanism that is configured to couple and decouple from a second end of the driven shaft such that a rotation of the gear mechanism when the gear mechanism is coupled to the second end of the driven shaft causes at least one of tightening and loosening of the collet.

A power tool includes a housing, a motor, an output member driven by the motor, and a reaming attachment coupled to the output member. The reaming attachment has a front end portion selectively driven in rotation by the output member to drive a fastener into a workpiece, and a reaming portion selectively driven in rotation by the output member to remove material from an end surface of a conduit. A rotational motion sensor in the housing is operable to detect rotational motion of the housing about an axis. A controller receives a signal indicative of rotational motion from the sensor, determines a direction of the rotational motion of the housing, and drives the motor in a direction corresponding to the direction of rotational motion of the housing.

Power tool having rotary input control

A chop saw includes a base assembly and a saw assembly pivotally attached to the base assembly. The base assembly has a workpiece-supporting plane. The saw assembly has a blade and a motor driving the blade. A hinged connection between the base assembly and a saw assembly allows a user to rotate the saw assembly from a position where the plane of the blade extends through the workpiece-supporting plane to a position where the plane of the blade does not extend through the workpiece-supporting plane. In such position, the plane of blade may be substantially parallel to the workpiece-supporting plane.
