An optical sight having a reference housing having a reference housing aperture formed therein; at least one reference point positioned within the reference housing aperture; an eclipsed ring having an eclipsed ring aperture formed therein; wherein the eclipsed ring includes a pivot aperture formed therein, wherein the eclipsed ring is pivotably coupled, via a pivot pin extending through the pivot aperture, to the reference housing such that the eclipsed ring may pivot relative to the reference housing and such that the eclipsed ring naturally pivots to a predetermined position, and wherein the eclipsed ring is pivotably coupled such that a first side surface of the eclipsed ring faces generally towards a second side surface of the reference housing; and at least one surface preparation on the first side surface of the eclipsed ring, wherein the surface preparation is visually distinguishable from a surface of the reference housing aperture.

1. Field of the Invention
This invention relates generally to optical sights. In particular, the present invention relates to an optical sight that may be used to determine whether a particular device or a component of a device is at a predetermined angle with respect to a given plane.
2. Description of Related Art
The exemplary embodiments of this invention will be described in detail, with reference to the following figures, wherein like reference numerals refer to like parts throughout the several views, and wherein:
FIG. 1 shows an exploded perspective view of a first exemplary embodiment of an optical sight according to this invention;
FIG. 2 shows a perspective view of a first exemplary embodiment of an optical sight according to this invention;
For simplicity and clarification, the design factors and operating principles of the optical sight according to this invention are explained with reference to various exemplary embodiments of an optical sight according to this invention. The basic explanation of the design factors and operating principles of the optical sight are applicable for the understanding, design, and operation of the optical sight of this invention.
It should also be appreciated that, as used herein, the terms “sight” and/or “archery sight” are used for basic explanation and understanding of the operation of the systems, methods, and apparatuses of this invention. Therefore, the terms “sight” and/or “archery sight” are not to be construed as limiting the systems, methods, and apparatuses of this invention. Thus, the terms “sight” and/or “archery sight” are to be understood to broadly include any instrument or device to aid in aligning a device with a target. For example, the terms “sight” and/or “archery sight” are to be understood to broadly include any strip, bead, crosshair, notch and post combination, and/or any other traditional or non-traditional instrument or device that is used to aid in aligning a device with a target, i.e., an electronic representation of such.
It should be appreciated that the optical sight or occlusion ring can be adapted to many applications where the presence of a “level” or alignment to a particular angle is needed. For example, the optical sight or occlusion ring of the present invention can be used in conjunction with gun sights, gun scopes, bow sights, compass roses, surveying equipment, and any other device used for determining direction or orientation, or where ready visual feedback of such may be of interest.
