Abstract:
The multiple nomograph system for solving ranging and ballistic problems in firearms includes a series of graphs or nomographs for the determination of the ballistic trajectory of a bullet in flight. The nomographs may be placed upon the reticle (16) of a firearm scope (10), or provided on media external to the scope, as desired. The scope reticle (16) includes at least one aiming point or aim point field to compensate for elevation and windage, with the vertical axis preferably being offset to compensate for precession at longer ranges. Stadia for determining angular target dimension(s) are included on the reticle (16), with a nomograph for determining apparent distance from the apparent dimensions being provided either on the reticle (16) or external to the scope (10). Additional nomographs are provided for the determination and compensation of non-level slopes, non-standard density altitudes, and wind correction, either on the reticle (16) or external thereto.
Abstract:
A compact Galilean-type zoom finder (100, 200) suitable for compact cameras. The zoom finder is comprised of four units (UI', UII', UIII', UIV' and UI", UII", UIII", UIV") having negative, negative, positive and negative refractive powers in order from an object side. The first and the fourth lens units (UI', UIV'; UII", UIV") are fixed and the second and the third lens units (UII', UIII'; UII", UIII") are moved to perform zooming. The moving framing window (FW) helps to delineate the field of view.
Abstract:
An integrated firearm or air gun sighting scope that measures and automatically compensates for human unsteadiness (Jitter and Trigger Jerk), angle of shot, distance of shot, and bullet ballistics. The scope uses a combination of shot simulation, attitude tracking and synchronized fire control to achieve excellent accuracy without major modifications to the firearm or air gun.

Abstract:
Various embodiments described herein comprise a scope for a firearm having a large range of zoom. The scope comprising a movable zoom selector for adjusting magnification of an image viewed through the scope. The scope further comprises an objective, an ocular, and an erector assembly positioned between the objective and ocular. The erector assembly comprises at least three optical elements movable relative to one another in response to operation of the zoom selector.
Abstract:
An improved telescopic gunsight and reticle for long-range shooting is provided. The reticle (18) can be used with any conventional telescopic gunsight as an optically transparent wafer or disc (19) thus having an optical center (21) which coincides with a center of field of vision when the reticle is mounted in a telescopic gunsight. The reticle includes a primary vertical cross-hair (20) having a predetermined thickness intersecting the optical center of the wafer, a primary horizontal cross-hair (22) having a predetermined thickness intersecting the primary vertical cross-hair (20), a plurality of secondary vertical cross-hairs (26) having a predetermined thickness evenly spaced along at least some of said secondary vertical cross-hairs (24) and a range-finding means (30) positioned in one of the quadrants formed by the intersection of the primary vertical (32) and horizontal cross-hairs (34).
Abstract:
A reflective truncated ball imaging system includes: a reflective truncated ball element having a first surface, a second surface and a third surface for reflecting incident light beams from an object having a width of X entering into the first surface, from the second surface towards the third surface to exit the third surface and form an image of the object with a width Y; a focusing lens for focusing the reflected light beams exiting the third surface; and a sensor or view finder for sensing or viewing the light beams focused by the focusing lens.
