A hand-held power tool is provided that includes a housing assembly, an output spindle, and a motor endbell. The housing assembly supports an electric motor having a rotor configured to rotate when the electric motor is supplied with power. The output spindle protrudes from an output end of the housing assembly, and is functionally coupled to the rotor such that the output spindle rotates in response to a rotation of the rotor. The motor endbell is located on the housing assembly adjacent the electric motor and opposite the output spindle. An illustrative controller is operable to determine phases of a fastening operation in which the hand-held power tool is operating. The phases of the fastening operation of the hand-held power tool include two phases including: (1) a continuous run phase and (2) an impacting phase.

Power tools with user-selectable operational modes

A hand-held power tool is provided that includes a motive source, a user interface, and one or more sensors. The motive source includes a printed circuit board (PCB) configured to support electrical components of the motive source. The user interface is movable between a plurality of mode positions to select one of a plurality of operational modes of the motive source. And one or more sensors are mounted on the PCB and are configured to detect the plurality of mode positions of the user interface.

Power tool user interfaces

A light emitting apparatus having a housing including a portion defining a thermally conductive outer surface, a light source positioned within the housing, and an internal heat sink thermally coupling the light source and the thermally conductive outer surface portion of the housing. The light source may be a solid state device, such as a light emitting diode.

Amplification circuit and heat sink used with a light emitting apparatus having varying voltages

A hand-held power tool is provided that includes a housing assembly to support a motor. An output spindle protrudes from an output end of the housing assembly such that the output spindle rotates in response to a rotation of the motor. A user interface is located at the housing assembly opposite the output spindle. The user interface is configured to select one of a plurality of modes of operation of the hand-held power tool to regulate power supplied to the motor.

A light emitting apparatus for regulating a current output of an LED at predetermined value with a power source having a wide variety of voltages and chemistries is described. A light emitting diode is electrically coupled to the voltage source. A pulse width modulation controller controls a duty cycle of the voltage applied. A resistor electrically coupled between the voltage source and the light emitting diode is used to regulate output current for the LED. An amplification circuit is electrically coupled to the resistor and the pulse width modulation controller for supplying a feedback voltage to the pulse width modulation controller that is higher than a voltage measured across the resistor.
