Patent number: 10575971Abstract: Hybrid terrain-adaptive lower-extremity apparatus and methods that perform in a variety of different situations by detecting the terrain that is being traversed, and adapting to the detected terrain. In some embodiments, the ability to control the apparatus for each of these situations builds upon five basic capabilities: (1) determining the activity being performed; (2) dynamically controlling the characteristics of the apparatus based on the activity that is being performed; (3) dynamically driving the apparatus based on the activity that is being performed; (4) determining terrain texture irregularities (e.g., how sticky is the terrain, how slippery is the terrain, is the terrain coarse or smooth, does the terrain have any obstructions, such as rocks) and (5) a mechanical design of the apparatus that can respond to the dynamic control and dynamic drive.Type: GrantFiled: July 30, 2018Date of Patent: March 3, 2020Assignee: Bionx Medical Technologies, Inc.Inventors: Hugh M. Herr, Rick Casler, Christopher M. Nook, Alexander S. Margolin, Kristin J. Size, Matthew T. Kowalczyk, Robert W. Spaller, Gregory K. Thompson, Timothy M. Dalrymple, Seth S. Kessler, David W. Murray, Christopher E. Barnhart

Patent number: 9206846Abstract: A ball bearing assembly having a bearing ball recirculation arrangement. The ball bearing assembly includes an outer ring having an inner surface, an inner ring having an outer surface and insertable inside the outer ring along a common longitudinal axis, and an insert removably fixed in a position between the outer ring and the inner ring. The outer ring, inner ring and insert define at least one ball bearing recirculation path. At least one set of bearing balls is disposed to travel along the at least one ball bearing recirculation path.Type: GrantFiled: April 28, 2014Date of Patent: December 8, 2015Assignee: Nook Industries, Inc.Inventors: Brian Joseph Fehr, Daniel J. Piltz, Alexander S. Margolin

Publication number: 20130199324Abstract: A ball screw assembly having a bearing ball recirculation arrangement. The ball screw assembly includes a ball screw, a nut, and at least one set of two return plugs and at least one cap. The nut body is in threaded engagement with the ball screw, wherein one of the ball screw and the nut body is rotationally fixed relative the other. Each plug may be seated into a cavity on an outer surface of the nut body. The cap may have a recessed channel at least partially defining a return path for bearing balls from one end of a load bearing path to another end of a load bearing path.Type: ApplicationFiled: January 23, 2013Publication date: August 8, 2013Applicant: NOOK INDUSTRIESInventors: Daniel J.
