Abstract: A prosthetic foot includes a foot portion and a switching adapter. The switching adapter includes a first member coupled to the foot portion, a second member, a third member interposed between the first member and the second member, and a locking mechanism. The third member has a first side wall and a second side wall larger in length than the first side wall. The third member is configured to rotate relative to the first member and the second member towards a first position, thereby placing the prosthetic device in a walking mode. The third member is further configured to rotate relative to the first member and the second member towards a second position, thereby placing the prosthetic device in a running mode. The locking mechanism is configured to rotate with the third member in response to rotation of the third member.

Abstract: Methods and systems for image processing are provided. A method for processing images of a scene includes receiving image data of a reference and a current frame; generating N motion vectors that describe motion of the image data within the scene by computing a correlation function on the reference and current frames at each of N registration points; registering the current frame based on the N motion vectors to produce a registered current frame; and updating the image data of the scene based on the registered current frame. Optionally, registered frames may be oversampled. Techniques for generating the N motion vectors according to roll, zoom, shift and optical flow calculations, updating image data of the scene according to switched and intermediate integration approaches, re-introducing smoothed motion into image data of the scene, re-initializing the process, and processing images of a scene and moving target within the scene are provided.

Abstract: The bur guard covers and removes foreign matter from burs protruding from a dental hand piece with an outer member, a foam inner member, and a mechanism to hold the foam taut enough to accept any bur shape, size, or texture thus, increasing the effectiveness of the bur and the efficiency of the dental procedure and while in position over the bur, will protect the dentist, dental assistant, and patient from a potentially infectious laceration or puncture wound.
