Abstract: A powered fastener driver includes a cylinder containing a pressurized gas, a piston within the cylinder and moveable from a top-dead-center position to a bottom-dead-center position, a driver blade moveably coupled to the piston for driving a fastener into a workpiece, and a lifter mechanism for providing torque to move the driver blade from the bottom-dead-center position toward the top-dead-center position. The powered fastener driver also includes a sensor configured to monitor a current draw of a motor of the lifter mechanism, and a controller is electrically connected to the motor and the sensor. The controller is configured to monitor the current draw of the motor, correlate, using an algorithm stored in the controller, the current draw to a pressure value. The controller is also configured to compare the pressure value to a predetermined pressure range and activate an indicator when the pressure value is outside the predetermined pressure range.

Abstract: A power tool including a housing, a trigger disposed on an outside of the housing, the trigger including a magnet, a motor within the housing, the motor configured to produce a rotational output to a drive mechanism, a Hall effect sensor configured to sense a position of the trigger based on a proximity of the magnet to the Hall effect sensor, and an electronic controller connected to the Hall effect sensor. The electronic controller is configured to determine the position of the trigger based on a signal from the Hall effect sensor and control the drive mechanism based on the position of the trigger.
