Patents by Inventor John D. Butkiewicz

John D. Butkiewicz has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Heading reference command and control algorithm systems and methods for aircraft turn-to-target maneuvers
    Patent number: 7630798
    Abstract: Systems and methods are provided for determining a final heading of a turning vehicle, such as a rotorcraft. The system may include an algorithm that calculates an advance prediction of a final heading that will be achieved after control input is terminated.
    Type: Grant
    Filed: August 5, 2005
    Date of Patent: December 8, 2009
    Assignee: The Boeing Company
    Inventors: David C. Mossman, John D. Butkiewicz
  • Heading reference command and control algorithm and cueing systems and methods for aircraft turn-to-target maneuvers
    Patent number: 7437223
    Abstract: Systems and methods are provided for determining a final heading of a turning vehicle, such as a rotorcraft. The system may include an algorithm that calculates an advance prediction of a final heading that will be achieved after control input is terminated. The system may also include a device, such as a display, for conveying predicted final heading information to an aircraft controller, such as a pilot.

  • Method and system for estimating robot tool center point speed
    Patent number: 5373221
    Abstract: A method and system is disclosed for estimating a speed of a robot tool center point at a specified time. The method includes the step of receiving an input signal representing the specified time for which the speed estimate is desired. The method also includes the step of processing individual motion segment data to create a blended Cartesian velocity vector. The individual motion segment data represents at least one robot motion segment. The method finally includes the step of transmitting an output signal based on a scalar magnitude of the blended Cartesian velocity vector. The output signal represents the speed of the robot Tool Center Point at the specified time.
