Abstract: One embodiment is directed to a brace for limiting motion of a joint of an appendage of that is interposed between a first appendage portion and a second appendage portion of a patient, comprising: an upper member removably coupleable to the first appendage portion, the upper member having proximal and distal ends; and a lower member removably coupleable to the second appendage portion, the lower member having proximal and distal ends; wherein the distal end of the upper member and proximal end of the lower member are coupled to form a movable joint that is substantially alignable with the joint of the patient, such that when the patient attempts to move his appendage and associated joint, motion is resisted at this joint in a nonlinear fashion.

Abstract: A system for processing agricultural items includes a first member having a first surface, a first axis, and a partially cylindrical space, the first surface being an inner surface of the partially cylindrical space. The system also includes a substantially arcuate second member having a second surface and a second axis, the second member being disposed at least partially in the partially cylindrical space, and the contoured second surface being an outer surface of the second member. The first surface and the second surface are substantially opposed to each other. One of the first and second surfaces substantially tapers toward another of the first and second surfaces along the first or second axes. The first and second axes are respective first and second circumferential axes.
