Abstract: In a system for authenticating information, a holographic element, including a first layer of optical information in a first coded pattern and a second layer of optical information in a second coded pattern is inserted into a reader. The reader includes an opening into which the holographic element may be positioned, a light source, a first detector positioned at a first predetermined distance from the location of the holographic element when the holographic element is positioned in the opening, and a second detector positioned at a second predetermined distance from the location of the holographic element when the holographic element is positioned in the opening.

Abstract: In an object verifier having a housing and an object holder, an object may be placed in the object holder for observation by an operator. The object is illuminated using a collimated beam of white light that is generated by a light generator. The collimated beam of white light is passed through a beam splitter with the two portions of the collimated beam of white light presented to the object at a 90 degree angle one from the other. The interior of the housing includes a reflective surface for maximal illumination of the object. The observer may view the illuminated object through a viewing window and/or through a magnification window. The magnification window provides for the viewing of the object in greater detail.

Abstract: A fisherman gripping glove system for efficiently gripping a fish without requiring usage of a fishing net. The fisherman gripping glove system includes a glove member having an inner layer, an intermediate layer and an outer layer. A plurality of particulate material is contained within the outer layer for facilitating gripping of a fish. The particulate material is preferably comprised of random and polygonal structures such as chippings from plastic.

Abstract: The tie back tack is used to secure a four-in-hand necktie to a shirt with minimal lateral movement of the necktie and without puncturing the front pendant of the necktie. A four link chain extends from the tie back tack and is attached to a removable clasp. The removable clasp attaches to the front edge of the shirt and keeps the necktie not only in place but centered at all times.

Abstract: A card having an uninterrupted strip of magnetizable material affixed to the surface of a substrate can carry a machine readable code in the form of a magnetized pattern. By removing alternate magnetized segments, in a column of parallel rifts across the strip, the machines readable code becomes non-alterable, since a uniform, unidirectional magnetization of the remaining material restores the original code.
