Abstract: A bending apparatus for a sample is disclosed. The bending apparatus includes a translation mechanism that translates a vertical displacement/force into a horizontal displacement/force for bending. Components of the bending apparatus are fabricated from a strong, radiolucent material. In these ways, the bending apparatus is compatible with micro-CT imaging, and as such, may be used to bend a sample during imaging. In a particular application, the bending apparatus may be used to measure biomechanical properties of a bone, such as bone strength, bone material properties, fracture toughness, and fracture propagation.

Abstract: A universal night vision goggle adapter (38) is provided for mounting a pair of night vision goggles (40) to a Special Purpose Test Set (10). The adapter (38) comprises slidably adjustable clamps (61 and 62) which are adjusted by a rotating rod (46). The rod (46) is rotationally supported by a bearing housing (44) which is in-turn fixed to a platform (42). The rod (46) is threadably attached at one end to a first bar (48) and threadably attached at another end to a second bar (50). The first and second bars (48 and 50) are fixed to the adjustable clamps (61 and 62) in such a fashion that as the rod (46) is rotated, the bars (48 and 50) are moved closer together or farther apart to adjust the clamps (61 and 62).

Abstract: A retainer ring (10) is provided to secure a lens (14) in a lens holder (12). The lens holder (12) has a groove (29) on its internal surface to match the external surface (34) of the ring (10). The lens (14) is placed in the lens holder (12) and the ring (10) is snapped into position in the groove (29) in lens holder (12) to secure the lens (14) therein. The lens holder (12) may then be inserted into an eyepiece (22) on a night vision goggle (20).

Abstract: A bracket (10) for releasably engaging a goggle (14) to a headgear (12). The bracket (10) includes a receptacle (52) with inside tapered sidewalls (124) matable with a goggle stud (55) having corresponding outer tapered sidewalls (125). A release lever (22) is housed in said stud (55) and includes a transverse notch (140) latchable with a lug (146) on a catch arm (144) adjustably fixed within the receptacle (52). The catch arm (144) is adjustable by an eccentric (162) while the goggle stud (55) is engaged within the receptacle (52).

Abstract: A headgear (10) for supporting a night vision goggle (12) to the head of a wearer. A flexible temporal strip (18) is joined to a flexible crown strip (20) in the forehead region, at which juncture a pair of integral rails (74, 76) suspend the goggle (12) therefrom. The temporal strip (18) and crown strip (20) include free ends which are directed toward the posterior of the cranium (22) and are connected by straps (36, 46, 48) to a webbed pad (38) which engages the occipital protuberance to prevent forward rotation of the headgear (10) due to the weight of the goggle (12). Lower girth straps (68, 69) maintain attachment of the headgear (10) to the cranium (22) and further aid in antirotational movement.

Abstract: An adjustment mechanism for adjusting headgear-mounted vision equipment with respect to the viewer's eyes. A goggle (14) is mounted to a carriage (20) which is slideable on a frame (10) mounted to the headgear (12). The carriage (20) is slideable on a rail (16) by a tongue and groove arrangement (48), and slideable on a rod (42). The carriage (20) includes a cavity (62) with a coil spring (64) therein encircling the rod (42). In its relaxed state, the coil spring (64) firmly engages the rod (42) and prevents movement of the carriage (20) on the rod (42). The coil spring ends (66, 68) are compressible together to release the engagement of the coil spring (64) about the rod (42). A finger-operated plunger assembly (28) includes a slotted end (118) for engaging one spring end (68). When the plunger button (116) is depressed, the spring ends (66, 68) are pressed together, thereby permitting adjustment of the carriage (20) on the rod (42).
