Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 87 words
An aiming device comprising: at least two bundles of straight parallel light collimating fibers having normal ends with diameters which are orders of magnitude less than their lengths, the fibers in each bundle being equal in length and the fibers in each bundle having a length to diameter ratio different from the fibers in every other bundle; and an illumination means attached to said bundles to illuminate one end of the fibers in each bundle with light of one color, the colors for adjacent bundles being different.
Claim 2
Dependent Claim 87 words
An aiming device comprising: at least two bundles of straight parallel light collimating fibers having normal ends with diameters which are orders of magnitude less than their lengths, the fibers in each bundle being equal in length and the fibers in each bundle having a length to diameter ratio different from the fibers in every other bundle; and an illumination means attached to said bundles to illuminate one end of the fibers in each bundle with light of one color, the colors for adjacent bundles being different.
Claim 3
Dependent Claim 18 words
The device according to claim 1 wherein: said fibers consist of hollow micro-channel tubes of light absorbing material.
Claim 4
Dependent Claim 29 words
The device according to claim 1 wherein: said one end of each fiber is aligned in a common plane and said illumination means is attached to said one end.
Claim 5
Dependent Claim 24 words
The device according to claim 1 wherein: the fibers in each bundle fill mutually exclusive cylindrically bounded zones about a common axis parallel thereto.
Claim 6
Dependent Claim 40 words
The device according to claim 1 wherein: said illumination source includes a plurality of sections of Day-Glo plastic, each section having a characteristic color and a shape to match the configuration of the fiber ends in one of said bundles.
Claim 7
Dependent Claim 31 words
The device according to claim 1 wherein: said illumination source includes a phosphor coating that glows at night covering only a portion of the fiber ends in at least one bundle.
Claim 8
Dependent Claim 22 words
The device according to claim 1 wherein: the longest of said fibers has a length to diameter ratio of at least 2000.
