Abstract: A system for electronically capturing a subject's anatomy. Software programming directs the user to position the camera to recognize the anatomy. It uses anatomical features of the recognized subject's anatomy, patient data entered by the user and anthropometric data to estimate the optimal position of virtual markers. Furthermore, it places the virtual markers on an image presented to the user on the display screen at the estimated optimal position, while utilizing an auto-zoom and the virtual markers to zoom in to provide proper framing. The auto-zoom is utilized while maintaining a substantially fixed camera distance from the subject. The programming provides feedback based on the anatomical features for directing the user to move the camera appropriately relative to the virtual markers, thereby resulting in an optimized view of the anatomical information. The end-user software program captures the optimized view of the anatomical information via the camera to provide output data.

Abstract: The current document is directed to a two-way, by-passable, overrunning clutch incorporated within a mechanical prosthetic knee that provides functionality similar to a biological knee or incorporated in another articulated device, such as a robotic or orthotic articulated device or member.
