A portable power driven system has a manually movable frame. In one example, an internal combustion engine and a generator device that generates AC power are supported on the frame. The internal combustion engine drives the generator device. An electrically powered starting device is coupled to the internal combustion engine. A control panel is coupled to the frame and includes at least one AC outlet and a battery receptacle that is electrically coupled to the starting device. The battery receptacle is materially the same as a foot of a cordless power tool that receives a battery pack. According to one aspect, the battery pack for the cordless power tool may be permanently mounted in the battery receptacle and provides electrical power to the starting device. The battery receptacle may be contained in an enclosure. The enclosure may provide biasing members urging the battery pack into the battery receptacle.

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.

A power tool includes a tool body having an output member that drives an accessory. An end effector is coupled for rotation with the output member. A light source is disposed on the end effector. A primary coil assembly is configured on the tool body and mounted concentric to the output member. The primary coil assembly includes a primary coil that is electrically connected to a power source of the power tool. A secondary coil assembly is configured on the end effector and mounted concentric to the output member. The secondary coil assembly includes a secondary coil that is electrically connected to the light source. Current flowing through the primary coil creates a magnetic field that causes current to flow through the secondary winding and power the light source.

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.

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.
