Abstract: An impact tool includes a housing, a motor supported within the housing, a drive assembly configured to convert a continuous rotational input from the motor to intermittent applications of torque on a workpiece, and first and second impact members supported on the drive assembly and configured to deliver impacts to one another. The first impact member includes a core made of a first material having a first hardness, and a sleeve surrounding the core and made of a second material having a second hardness different than the first hardness. The first hardness is less than the second hardness.

Abstract: An impact tool and a hammer. The impact tool includes a housing, a motor supported within the housing, an anvil extending from the housing, and a drive assembly configured to convert a continuous rotational input from the motor to intermittent applications of torque to the anvil. The drive assembly includes a camshaft driven by the motor and a hammer configured to reciprocate along the camshaft. The hammer includes a core coupled to the camshaft and a sleeve coupled to the core.

Abstract: A power tool includes a housing, a motor positioned within the housing, an output mechanism rotatably supported within the housing, and a gear assembly positioned within the housing. The output mechanism is configured to rotate about a longitudinal axis. The gear assembly is coupled between the motor and the output mechanism to transfer a torque generated by the motor to the output mechanism. The gear assembly includes a ring gear, a cylindrical interior bearing surface adjacent the ring gear, and a planet gear. The planet gear includes a planet gear portion configured to mesh with the ring gear to rotate the output mechanism about the longitudinal axis, and a planet bearing portion that defines a cylindrical outer bearing surface. The cylindrical outer bearing surface is configured to roll along the cylindrical interior bearing surface to radially support the output mechanism for rotation about the longitudinal axis.

Abstract: Methods and systems are provided for controlling network service quality. According to an aspect of the invention, a computer-implemented method is provided for controlling levels of quality of service (QoS) for transmitting data between a terminal and a destination. The method comprises enforcing a first level of a QoS to a connection between the terminal and the network, receiving a user-requested, second level of the QoS from the terminal, identifying a currently-available level of the QoS on the network, determining a third level of the QoS based at least in part on the currently-available level of the QoS on the network and the second level of the QoS, and enforcing the third level of the QoS. Methods and system are provided for enabling users at the terminals to specify online a level of network QoS, and the system dynamically changes the quality level and the plan to satisfy the request.
