Abstract: An external bone fixation system may include a first semi-circular external fixation member, a second semi-circular external fixation member, four ball collet assemblies attached to the second external fixation member, and four shafts. Each shaft may include a first end attached to the first external fixation member and a second end with a stop member, and each of the four shafts extends slidably through an opening in a ball of one of the four ball collet assemblies. The stop member of each second end prevents each second end from passing through the opening in its respective ball. Each shaft also includes a hinge located closer to the first end than to the second end.

Abstract: An external fixation assembly for bone fusion or separation is disclosed. The assembly includes a fracture fusion tube, with a bracket slidably engaged thereon. The assembly further includes a collet clamp connected to the bracket, with a ball collet rotatably seated within the clamp, the ball collet having an aperture for receiving a bone bin therethrough and perforations for a compression engagement with a bone pin. The assembly uses a single screw for threadably engaging the ball collet, the clamp and the bracket such that the position of the bone pin, ball collet and bracket are all fixed.

Abstract: An inflatable evacuation ramp for evacuating people from a building during an emergency situation may include an inflatable slide having a length at least long enough to extend from a window on a second floor of the building to the ground and a window attachment member coupled with one end of the slide, for attaching the slide to a window frame on the building. A method for evacuating a person from a building during an emergency situation may involve attaching one end of an inflatable slide to a window frame of the building, inflating the inflatable slide so that it extends from the window frame to ground near the building, and sliding the person down the slide to the ground.
