Abstract: Apparatuses, systems, and methods for measuring portions of a body are disclosed herein. In one embodiment, an apparatus includes a disposable subassembly and a reusable subassembly releasably coupled to the disposable subassembly. The disposable subassembly includes a flexible member for positioning relative to the portion of the body. The reusable subassembly includes an encoder for detecting movement of the flexible member, a processor operably coupled to the encoder for receiving data corresponding to a dimension of the portion of the body, and an output device operably coupled to the processor for sending data to an external device.

Abstract: Braces having an assembly for exerting a manually adjustable force on a limb of a user are disclosed herein. In one embodiment, a brace includes a first frame portion, a second frame portion, a hinge movably coupling the first frame portion to the second frame portion, a flexible member positioned relative to the first and/or second frame portion for exerting a force on the limb of the user, and a tensioning mechanism for manually adjusting a tension in the flexible member to vary the force exerted on the limb of the user. The force exerted by the flexible member is generally independent of the position of the first frame portion relative to the second frame portion.

Abstract: Bicentric hinges for use in braces and methods for operating knee braces and other types of braces are disclosed herein. In one embodiment, a hinge includes a plate, first and second members pivotally coupled to the plate, and a rocker coupled to the plate. The first member is pivotable about a first axis of rotation, and the second member is pivotable about a second axis of rotation spaced apart from the first axis of rotation. The second member is not directly engaged with the first member, and the first member may not be connected to a return mechanism that urges the first member to pivot about the first axis of rotation. The first member has a first recess, and the second member has a second recess. The rocker includes a head at least partially receivable in the first recess and/or the second recess to restrict rotation of one of the first and second members until the other has rotated.

Abstract: A reinforcement assembly to reinforce a selected site on a body, and methods of making and using such a universal reinforcement assembly. Several embodiments of reinforcement assemblies in accordance with the principles of the invention are well suited to support or reinforce laminated structures. In one embodiment, the reinforcement assembly has a reinforcement member configured to be attached to the selected site on the body and a universal attachment medium separately bonded to the reinforcement member. The reinforcement member may be a plate composed of a molding compound, a high density polymer, or another suitable high-strength material. The universal attachment medium, more specifically, may have a first section bonded to the reinforcement member and a second section extending from the reinforcement member to cover an area of the body substantially surrounding the selected site.
