Abstract: Disclosed is a method of fabricating a prosthetic member (112) having personalized features of the patient, and being formed to provide an individualized fit to the patient's extremity (18). A rigid jacket (30, 32) is first formed around the uninsured foot (10) and the amputated extremity (18). The limb characteristics are impressed into an alginate (44) lining within the jackets (30, 32). A stone material poured into the alginate lining (44) forms stone models (48, 50) of the patient's limbs. A wax preliminary model (64) is scuplted in the likeness of the stone foot model (48) and used to form final stone mold halves (100, 102). The contour of the stone extremity model (50) is adjusted according to the tissue texture of the patient to provide an individualized fit. A gelatinous silicone is injected inside the final mold (100, 102) and allowed to form around the extremity model (50) to thereby provide the body of the prosthetic member (112) and the conformal sleeve (132 ).

Abstract: A taxidermic specimen and a method of formation thereof is disclosed. A preliminary negative mold (28) is formed by applying an alginate material to the jaw structure of the animal carcass. Fibers (50) are disposed within the depressions (30, 32 and 34) to provide tooth stains. Tooth-colored acrylic material is alternately poured in layers into the teeth depressions (30, 32 and 34) of the preliminary mold (28). The hardened acrylic teeth (44, 46, 48) are removed and chamfered around the gingival line (40).

Lower girth straps (68, 69) maintain attachment of the headgear (10) to the cranium (22) and further aid in antirotational movement.

Abstract: An eyecup (24) for interfacing a night vision goggle (10) with the eyes of the user (12). A flexible curved eyepiece (28) including a wing (38) provides a tight seal of the periphery of the eyepiece (28) to the occular eye area of the user (12). The seal prevents light (22) emitted from the goggle (10) from escaping out of the confines of the eyecup (24). A fastening sleeve (26) is provided to secure the eyecup (24) about a flange on the goggle (10). An intermediate accordion section (40) allows compression and expansion and maintains the seal between the eyepiece (28) and the ocular eye area. An air vent hole (52) is formed in the accordion section (40) to prevent suction from occurring within the eyecup (24).
