Abstract: A day/night weapon sight assembly that consists of daytime sight and a nighttime sight allows the use of both sights without change in eye relief even when the nighttime sight is attached to the rear end of the daytime sight. This is achieved by supporting the daytime sight moveably in the direction of the optical axis and by supporting the nighttime sight with the use of a plane-parallel motion mechanism that allows switching of the nighttime sight between the upper inoperative position and the operative position behind and coaxially with the daytime sight.

Abstract: An optical scope with a position-based on/off switch preserves power by automatically deactivating one or more electrical components when the scope is not in use. The scope includes an orientation sensor that determines when the scope is in an inactive position by sensing when the scope is rolled left or right to a predetermined angle of inclination from an upright position. A power switch receives an indicia of orientation from the orientation sensor and deactivates the one or more electrical components when the scope is in the inactive position, thus preserving power and extending the life of a battery.

Abstract: A rifle scope system allows adjustment of the scope while a shooter maintains the shooting posture and the scope sight picture. The scope system comprises an adjustment system comprising an electromechanical mechanism that responds to a signal from a remote controller manipulated by the shooter without having to significantly disturb the shooting posture. The adjustment system allows the shooter to adjust the scope's point of aim to coincide with a bullet's point of impact at a target. Such adjustment can be performed either by the shooter. Alternatively, such adjustment could be performed by a processor configured to adjust the point of aim based on a ballistic parameter associated with the bullet or the shooting environment. The adjustment system allows such processor-determined adjustments to be effected in a quick manner.

Abstract: The digital elevation knob is a digital replacement for a conventional elevation knob of a telescopic rifle sight. The knob is mounted to the rifle scope by a cylindrical body having a pair of flanges. The flanges are adapted for securing a microcomputer to the knob. A display screen is disposed on the front surface of the microcomputer. Inputs supply data to the microcomputer that processes the data. When the elevation knob is turned it turns a screw that is secured to a targeting element. The screw causes the targeting element to move vertically. A displacement sensor determines how much the targeting element has moved and sends a signal to the microcomputer. The input data and the information from the sensor are processed using trajectory programs and ballistic tables. The results of the data processing are projected on the display screen. The display informs the rifleperson of necessary adjustments.

Abstract: A vertical adjustment mechanism for weapon's sights such as riflescopes that includes moveable indicator flags for indicating zeros at various ranges. These flags can be moved independently and are separated by spacers that are keyed to the central shaft in to prevent the movement of one flag from disturbing the setting of the other flags. The adjustment also includes a graduated dial that indicated angular change in the adjustment to facilitate the setting of the indicator flags and to provide a zero point for orienting the system. Once adjusted, the entire assembly is locked together by tightening screws that clamp the separate pieces together so it will function as if it was a single unit. The adjustment mechanism can be applied to the internal components of a telescopic sight or to an external mount.
