Publication number: 20130284471Abstract: A power tool includes a housing, an output member that rotates about a longitudinal axis, and a motor drivably connected to the output member. A rotational motion sensor is arranged in the housing and operable to detect a user input that includes a rotational motion of the housing in a desired rotational direction about the longitudinal axis of the output member. A controller is configured to receive a first input indicative of a user-desired rotational motion of the output member, and a second input, from the rotational motion sensor, indicative of an actual rotational motion of the power tool. The controller determines a user-desired rotational direction of the output member about the axis from the first input, determines an actual rotational direction of the housing about the axis from the second input, and causes the motor to drive the output member to simulate ratcheting movement in the user-desired rotational direction.Type: ApplicationFiled: January 31, 2013Publication date: October 31, 2013Inventors: Scott J. Eshleman, Craig A. Schell, Andrew E. Seman, JR., Daniel Puzio, Daniele C. Brotto, Joseph P. Kelleher, Sankarshan Murthy

Patent number: 8418778Abstract: An improved method is provided for operating a power tool. The method includes: monitoring rotational motion of the power tool about an axis using a rotational motion sensor disposed in the power tool; determining a direction of the rotational motion about the axis; and driving the output member in a direction defined by the detected rotational motion of the tool, where the output member is driven by a motor residing in the power tool. Thus, the output member is drive clockwise when the rotational motion of the tool is clockwise about the axis and the output member is drive counter-clockwise when the rotational motion of the tool is counter-clockwise about the axis.Type: GrantFiled: February 24, 2012Date of Patent: April 16, 2013Assignee: Black & Decker Inc.Inventors: Scott Eshleman, Craig Schell, Andrew E.
