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.

Patent number: 8408327Abstract: A method for operating a driving tool, such as a fastening tool, that has a driver, a motor assembly with a motor and an output member, and an electrical power source. The methodology includes transmitting electrical power to the motor to rotate the output member and thereafter adjusting one or more control parameters if a rotational speed of the output member is not within a predetermined operating range.Type: GrantFiled: March 31, 2005Date of Patent: April 2, 2013Assignee: Black & Decker Inc.Inventors: Michael Forster, Bhanuprasad V. Gorti, Sam Woods, Craig Schell, Nathan Cruise

Patent number: 8286723Abstract: A power tool includes an output shaft configured to rotate about a longitudinal axis, a motor drivably connected to the output shaft to impart rotary motions thereto, and a rotational motion sensor spatially separated from the output shaft and operable to determine the user-imparted rotational motion of the power tool with respect to the longitudinal axis. A controller is electrically connected to the rotational motion sensor and the motor. The controller determines angular velocity of the power tool about the axis, rotational displacement of the power tool about the axis, and/or a direction of the rotational displacement using input from the rotational motion sensor. The controller then controls the motor according to the angular velocity, the rotational displacement, and/or the direction of the rotational displacement.Type: GrantFiled: January 7, 2011Date of Patent: October 16, 2012Assignee: Black & Decker Inc.Inventors: Daniel Puzio, Craig Schell, Daniele Brotto, Andrew Seman, Jr., Scott Eshleman, Joseph Kelleher, Sankarshan Murthy, Gabriel Concari, Thomas Bodine, Michael Haupt, Curtis Watenpaugh

Patent number: 7681659Abstract: A control system is provided for use in a power tool. The control system includes: a rotational rate sensor having a resonating mass and a controller electrically connected to the rotational rate sensor. The rotational rate sensor detects lateral displacement of the resonating mass and generates a signal indicative of the detected lateral displacement, such that the lateral displacement is directly proportional to a rotational speed at which the power tool rotates about an axis of the rotary shaft. Based on the generated signal, the controller initiates a protective operation to avoid further undesirable rotation of the power tool. The controller may opt to reduce the torque applied to shaft to a non-zero value that enables the operator to regain control of the tool.Type: GrantFiled: January 14, 2008Date of Patent: March 23, 2010Assignee: Black & Decker Inc.Inventors: Qiang Zhang, Uday Deshpande, John Charles Vanko, Jason Lee, Craig Schell, Thomas Jay Bodine, Joao Norona, David Beers
