    摘要： A motor control module for a power tool includes a controller and a triac for controlling current to the given tool motor. The module includes a circuit within the controller for implementing a plurality of control methodologies related to synchronizing the module to the AC input signal, estimating average current flowing through the triac, compensating for amplifier offset to improve accuracy of current measurements in the module, and providing speed measurement and control for the tool motor using principles of hysteresis in a comparator of the controller. Additionally, the controller is configured to calibrate an oscillation calibration register therein.

    摘要： An overspeed protection subsystem is provided for a power tool having an electric motor. The overspeed protection subsystem is comprised of: a motor switch coupled in series with the motor; a motor control module interfaced with the motor switch to control switching operation of the motor switch; and an overspeed detection module that determines rotational speed of the motor and disables the power tool when the rotational speed of the motor exceeds a threshold.

    摘要： 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, the guard assembly having a first state for providing a first level of protection and a second state for providing a second level of protection, 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 in the first state or the second state. Before the motor is started, the control system automatically disables the motor if it determines that the guard assembly is in the second state. The control system includes a bypass switch for enabling starting of the motor when the guard assembly is in the second state.

    摘要： A fastening device that drives one or more fasteners into a workpiece generally includes a tool housing and a multistage solenoid contained in the tool housing. The multistage solenoid includes an armature member that travels through at least a first stage, a second stage, and a sense coil disposed therebetween. A driver blade assembly includes a blade member connected to the armature member. The driver blade assembly is operable between an extended condition and a retracted condition. A control module determines a position of the armature member relative to at least one of the first stage and the second stage based on a signal from the sense coil. The control module adjusts a force imparted on the armature by at least one of the first stage, the second stage, and a combination thereof based on the signal from the sense coil.

    摘要： A portable generator system having a generator for generating an electrical output signal, an internal combustion engine for driving the generator, a starter for starting the internal combustion engine, an alternator for generating an AC signal for powering a charger assembly, a battery pack, and a charger subsystem. The charger system has a charger assembly that receives the AC signal and generates a DC charging signal for recharging the battery pack. The charger assembly has a first switch and a second switch. The first switch is used to apply an output of the battery to energize the starter. The second switch, when placed in a Start position, enables current from the battery pack to energize the starter while inhibiting the application of the DC charging signal to the battery pack. When placed in the Charge position, the second switch inhibits the battery pack output from energizing the starter while enabling the DC charging signal to be applied to the battery pack.
