Abstract: A method and system for creating three-dimensional models of implant-bearing dental arches, and other anatomical fields of view, employs three-dimensional scanning means to capture images of an anatomical field of view wherein there have been positioned (and preferably affixed to an anatomical feature) one or more three-dimensional recognition objects having a known geometry, such as a pyramid or a linked grouping of spheres. Image processing software is employed to locate and orient said recognition objects as reference data for stitching multiple images and thereby reconstructing the scanned field of view. Recognition objects placed in areas of low feature definition enhance the accuracy of three-dimensional modeling of such areas.

Abstract: Disclosed is a golf ball designed for longer travel relative the compression of the ball. The golf ball includes: (1) a flexible inner core, preferably comprised of crosslinked synthetic rubber, (2) a perforated barrier shell positioned outside of, and surrounding, the inner core to lessen deformation of the ball when the ball is struck by a golf club, (3) a flexible outer core, preferably comprised of crosslinked, synthetic rubber or windings, positioned outside of and surrounding the perforated barrier shell, and (4) an outer cover, preferably comprised of ionomeric resin material, positioned outside of and surrounding the outer core. The perforated barrier shell reduces deformation of the golf ball upon impact by a golf club and is preferably formed as a sphere centered in the golf ball, preferably having a diameter equal to one-half the diameter of the golf ball.

Abstract: A reusable or disposable rodent trap is described having only two discrete parts, particularly suited for trapping small animals including rodents such as mice, in which the trapped animal may be made to expire by asphyxiation rather than trauma or poison. The trap comprises an enclosure typically having the shape of an elongated box with an opening at one end, and closing said opening a hinged one-way door adapted to swing freely upward into the enclosure to permit entry into the enclosure by an animal, said door having on its surface a plurality of small orifices to allow the diffusion to the exterior of the trap of scent from bait placed within the otherwise nearly air-tight trap. A rodent attracted by bait scent emanating from the orifices in the door is able to enter the trap by pushing against the closed door, thereby causing it to pivot upwardly open into the enclosure.
