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.

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.

Ball bearing assembly

A no-lash nut assembly for installation on a threaded rod and including a lead nut, a trailing nut, a transition nut and a torsion spring. The lead and trailing nuts have threaded bores for mating with the rod. The trailing nut has an external surface configured for engagement with the lead nut to prohibit relative rotation and allow relative axial movement. The transition nut has a threaded bore for mating to trailing nut, an external surface defining a slot, and a front face having a mating surface corresponding to the rear face of the lead nut to allow relative axial movement between the lead nut and the transition nut. The torsion spring has a pin and a hook. The pin protrudes into the rear face of the lead nut and the hook protrudes into the transition nut slot to apply a rotational force on the transition nut.
