Abstract: An intramedullary nail has a proximal part for engagement with a proximal bone fragment and a distal part for engagement with a distal bone fragment. A motion assembly interconnects the parts and allows limited axial relative motion of the proximal and distal parts. This limited axial motion provides micromotion and in some embodiments also dynamization. The nail may comprise a stem for fastening to one bone fragment and an insert within the stem for fastening to the other bone fragment, the insert being adapted to guide insertion of a bone screw through the stem and to prevent relative rotation of the distal and proximal bone fragments. The motion assembly may include spring bias and/or damping means between the parts, possibly including one or more Belleville washers.

Abstract: An accessory holder that is to be used in such a way to securely hold ones accessories like keys (40), cameras (44), cellular phones, pagers, tape measures, and hand drills when they are not in use and to allow the person quick access to these accessories when they are needed. The preferred embodiment uses a modified seat belt buckle to carry A set of keys (40). Female end (25) is attached to the users belt (32) bag, or other convenient location. Male end (24) is attached to the accessory. When the accessory is needed, the user pushes button (26), and the accessory falls into the users hand. To return the accessory to female end (25), male end (24) must be inserted into opening (36). Male end (24) is pushed over the spring loaded locking mechanism and a distinctive “click” is heard once male end (24) is locked in place. The accessory can be conveniently carried in female end (25) until next time it is needed.

Abstract: A lock-keeper security shield plate assembly arranged over the usual lock-keeper plate which is in a routed recess of the wooden door jamb lock rail. The reinforcing shield plate is zig-zag shaped having an upset center section and two integrally formed angle face plates, shaped for one said shape to fit all width door frames with door stop rails that also vary in face width. One said face plate defines a bolt opening that is to be aligned with a bolt aperture of an underlying lock-keeper plate of a dead bolt mechanism, the other face plate defines a screw aperture in a key location in relation to a tubular dead bolt lock cylinder assembly mounted on a said door that virtually prevents tampering with the elongated anchor screw driven through said screw hole, through face of stop rail of wood jamb and framing studs there behind, said location of anchor screw in space relation to said lock cylinder rim prevents the removal of said anchor screw (door closed).
