Abstract: An articulating drill system is provided that includes a hand-held portion and a drill portion. At least two actuators are provided for controlling at least two axes of the drill portion. A navigation system is provided to control the at least two actuators. In some embodiments, a tool is provided with the drill portion and adapted to interact with patient tissue. The drill portion can be modified to include at least two rigid objects in communication with the actuators and attached to the drill portion. The system can be used to make any linear cut within a deviation of 1.0 mm and 1.0?, or better in patient tissue.

Abstract: Gun scope and action cover comprises a water-proof, breathable/air-permeable, reversible, light-weight, highly-flexible fabric pouch formed by an enclosed, cinchable elastic cord that fits over the optical scope of a rifle or hand gun, and that is universal in size, quiet in use, easy to put on and take off, and easy to store. The pouch area, formed by cinching and locking the cord, is bounded with an extended skirt that drapes down over the mechanical action of the gun. 2-ply waterproof/breathable fabric is preferred. Additional features include a securing cord for adding camouflaging ghillie strips, hook and loop fastener silencer(s) that prevent accidental adhesion to clothing, the release of which causes game-spooking sound, and a pocket for a warmer unit. The cover employs a variety of camouflage patterns on one or both sides, or one side may be a dark, a light, or a safety color, such as neon orange.

Abstract: The present invention relates to a fabric cover for encasing a flotation device. Loops are attached to the cover along the periphery of the cover to allow the user to secure additional flotation devices or anchors to the cover. The covering is preferably made from porous fabric that dries rapidly, that is relatively impervious to exposure to sunlight, saline solutions, and aqueous chlorine solutions and that has a “soft” feel against the user's skin.
