Abstract: There is disclosed a clip-on bracket assembly for detachably coupling to a first fixture comprising a first bracket member having an inner surface and an outer surface, the inner surface including a first planar surface portion and a second arcuate portion. A second bracket member substantially parallel to the first bracket member has an inner surface and an outer surface. The second member inner surface includes a first planar portion and a second arcuate portion wherein the first planar portions of the first and second members are fixedly coupled by means of an at least one spring washer. The second arcuate portions of the respective members are in parallel arrangement defining a gap therebetween for receiving and securing the fixture, where the first arcuate portion is springably movable with respect to the second arcuate portion to accommodate fixtures of varying widths.
Abstract: A range finder for a cap for determining the distance to a golf flag. The range finder has a cap coupling portion having a thin shell portion adapted to conform with the cap and a pair of "u" shaped portions for hooking around an edge of the cap. A base is carried by the cap coupling portion. A first support is pivotally mounted to the base at a first pivot point. A lens is carried by the first support. A second support is pivotally mounted to the base at a second pivot point. An index for viewing through the lens is pivotally carried by the second support. The range finder has a linkage bar pivotally mounted at a third pivot point to the first support and pivotally mounted at a four pivot point to the second support. Moving the lens from a retracted position to a flipped down, in use position moves the index in unison.
Abstract: In a system for planning, visualizing, tracking and analyzing physical objects such as merchandise in a retail space, a transponder is attached to each object and the transponders are interrogated periodically by a transmitter. Receivers receive the transponder signals and direct the received signals to a location processor which determines the location of each object. The locations of the objects can be displayed in various formats on a two or three dimensional map of the space. When objects are moved, they are interrogated more frequently so that traffic patterns in the space can be displayed.

Abstract: An apparatus and associated method for projecting a light pattern onto a target object, wherein the light pattern has a generally uniform brightness with well defined boarders. The apparatus includes a fiber optic conduit that emits a beam of light along an optical path. Light emitted from a fiber optic conduit typically contains a central region of a predetermined brightness and a peripheral region, created by light interference patterns, where the light is less bright. A first adjustable optical diaphragm is disposed along the optical path proximate the fiber optic conduit. By selectively varying to aperture of the first optical diaphragm, the diameter of the beam of light propagated along the optical path can be controlled. A second adjustable optical diaphragm is disposed along the optical path a predetermined distance away from the first optical diaphragm.
Abstract: An optical device comprising a spectacle frame having a pair of optical lenses. The optical device further includes a lens assembly pivotally attached to the spectacle frame which is pivotable between an operative position and a non-operative position. The optical device also includes an detent mechanism for repeatedly positioning the lens assembly into the operative position from the non-operative position. The lens assembly includes a support bracket for holding a pair of telescopes. The support bracket is contoured to the shape of the spectacle frame so that the bracket is substantially out of a user's forward line of sight when the lens assembly is in the operative position.

Abstract: An optical spectacle device comprising a spectacle frame having a pair of optical lenses. The spectacle device further includes a telescopic lens assembly pivotally attached to the spectacle frame which is pivotable between an operative position and a non-operative position. The spectacle device also includes an indexing mechanism for repeatedly orienting the telescopic lens assembly into the operative position from the non-operative position. A support frame for holding the telescopes of the telescopic lens assembly is adapted to be substantially out of a user's forward line of sight when the telescopic lens assembly is in the operative position.
Abstract: A rack for simultaneously storing prisms having varying sizes and shapes, comprising a plurality of clamps for holding the prisms. Each clamp includes a fixed clamping block and an oppositely disposed movable clamping block for enabling the clamp to self-adjust to the size and shape of a prism to be held therein. The clamps are mounted in a frame which includes a clamp supporting cross-member for mounting the clamps to the frame.
Abstract: An adjustable lens rack capable of retaining a plurality of lenses of varying sizes and shapes in rows. Lenses within each row are retained within a pair of lens retaining bars which extend between two ends of a frame. At least one retaining bar is movably adjustable with respect to the other retaining bar, thus enabling retention of a different type of lens for each row. In an illustrative embodiment, each retaining bar has a plurality of channels for receiving peripheral portions of the lenses, and each retaining bar is slidably adjustable via slots in opposing ends of the frame.
Abstract: A method and apparatus for allowing a user who wears spectacles including at least one lens having a positive magnification factor, to view a distant object through both the lens of the spectacles and a telescope. The method comprises the step of positioning a lens in the optical path of the telescope. The lens placed in the optical path of the telescope is adapted to cancel the positive magnification factor of the lens of the spectacles to maintain the afocal characteristic of telescope. The apparatus comprises at least one afocal telescope defining an optical path having a first lens oriented in the optical path for magnifying a distant object to be viewed through the afocal telescope system. The telescope further comprises a second lens oriented in the optical path for cancelling the positive magnification factor of the lens to maintain the afocal characteristic of the telescope.
Abstract: An apparatus for enabling a user having a visual handicap indicative of a condition designated as double vision to obtain substantially binocular vision comprises a first prism associated with the left eye of the user and having a base and a first prismatic deviation, a second prism having a base and a second prismatic deviation different from the first prismatic deviation, and a rotating assembly for rotating the prisms until a binocular vision field is viewable through the prisms by the user. The prismatic deviations are selected so that rotation of the prisms aligns them in a manner which permits the brain to fuse the respective images viewed by each eye into a single image, thereby providing a binocular image field. If desired, corrective lenses which accommodate the far or near distance prescriptions of the left and right eyes may mounted in alignment with the corresponding prisms.
