Abstract: Disclosed herein are strut attachments for external fixation frames. The strut attachments provide solutions for frame configurations in which it is not possible to attach a strut at its ends to corresponding rings. The strut attachments may be considered an outrigger type of mechanism that achieves more travel out of completely collapsed struts. The strut attachments, each having a pivot and a hinge joint, allow a strut to be attached on the level of a first ring and extend at least partially proximally or distally to a second ring depending on the frame of reference of the ring system. These strut attachments may be used when the fully collapsed length of the strut will not allow the rings to get any closer to one another than is needed or proscribed. In such cases, the strut attachments allow for even tighter ring to ring distance.

Abstract: These joints are particularly useful for transmitting a flux (electrical, optical, liquid or gaseous) either entirely across the joint, or from one side of the joint to devices mounted on the joint itself that use such a flux. Such devices can, for example, be motors to drive the joint itself. The interlocking bodies are typically but not necessarily circular rings, mounted to a common internal structure that permits each body to rotate about its own axis. The resulting joints can rotate in all directions with a very high angular range--in most cases limited only by the angle subtended by connecting stems used to mount the joint to a base or to mount objects to the joint for motion. Some of these joints have hollow central enclosures for passing flexible wires or tubing to carry the flux, so that the flux can be transmitted across or into the joint with the same high degree of freedom, and yet without slip rings, brushes, or other expensive motionaccommodating components subject to wear.

Abstract: A more efficient wind power generation system is afforded by extending tower heights to several hundred meters to operate wind catching rotors and generators aligned with the wind direction at various levels along the tower. With multiple vertically cascaded wind generators and higher velocity winds at higher elevations greater power is produced in a system characterized by a small footprint. This is particularly enhanced by a single mast construction, which is supported by a dynamic guy wire tensioning system to accomodate varying lateral forces primarily caused by the change in direction of wind loads on the tower. The mast is built from modular sections connected together at articulated joints, between which the various rotors are stationed.
