Abstract: An interference fit screw driver has a polygonal driving surface to impart torque to a corresponding surface in a screw. The end of the polygonal driving surface has a frusto-conical shaped gripping member which fits into an aperture in the screw to create a friction fit between the screw and screw driver. This allows the screw to be attached to the screw driver to facilitate installation of the screw. The friction fit is tight enough to hold the screw to the driver, yet allows the driver to be easily disengaged from the screw by pulling the driver away from the screw once the screw is lodged in place. The interference fit screw driver is particularly useful in turning bone screws into the spine of a patient during orthopedic surgery.

Abstract: A tool operates with a guide system to identify the orientation of a tool on a work piece. In one implementation, the tool identifies its orientation with respect to a guide signal supplied by the guide system. In an alternate embodiment, the tool determines its absolute orientation, such as a (x, y) coordinate. The tool includes an action component adapted to alter the work piece, such as a cutting head in a router. A guide detector in the tool detects a position of a guide signal from the guide system. A location detector in the tool receives the position data and employs it to determine the tool's orientation. Based on the detected orientation, the tool decides whether any tool adjustments are necessary. Examples of tool adjustments include the following: adjusting the position of the action component, enabling or disabling the action component, and providing operating indicators to direct a tool operator's use of the tool.
