Abstract: This invention discloses a riflescope wherein the point of aim is adjusted by a pair of partially-rotating wedge prisms. The prisms are positioned in front of the objective lens of the riflescope. The deviation axes of the prisms are oriented perpendicular to each other such that one deviates the light beam in the horizontal direction and the other in the vertical direction. It is shown, using the geometric properties of a tangent to a circle, that rotating each prism by a small amount can produce an approximately linear shift in the point of aim of the riflescope. The riflescope introduced in this invention has no laterally-moving parts, no turrets and no off-axis optical components. Therefore, it provides a very robust and reliable point of aim. Additionally, the riflescope has a streamlined body which is aesthetically pleasing and easier to mount on the long receiver of magnum hunting rifles.

Abstract: An adjustable reflex sight comprising an elongated sight housing comprising an outer tube and an inner tube pivotably mounted within the outer tube and holding an optical element for pivoting movement therewith, a sight adjustment mechanism mounted to the housing having an adjustable member movably mounted within the adjustment mechanism for altering a tilt angle of the inner tube in relation to the outer tube thereby adjusting the sight, a first adjustment device interlinked with a second adjustment device, wherein the first adjustment device is adjustably positionable about an axis of rotation for actuating said adjustable member, thereby altering the tilt angle of the inner tube, and the second adjustment device is adjustably positionable about the axis of rotation, such that the interlinked first adjustment device and the adjustable member are moved along the axis of rotation in response to rotation of the second adjustment device.

Abstract: A reflex sight includes an elongated sight housing having an outer tube and an inner tube defining a light channel with an optical axis, wherein the inner tube is pivotally secured within an end of the outer tube and has an end section forming an outer perimeter section, which is provided with separate convex sections. The separate convex sections of the inner tube are arranged to fit into the separate concave support sections in the outer tube, wherein the end section of the inner tube is pivotally received within the end section of the outer tube.

Abstract: This invention discloses a method for correcting the point of aim in riflescopes or other optical weapon sights. The point of aim is corrected by attaching one or more corrector wedge prisms in front of the riflescope. Each wedge prism shifts the point of aim by a predetermined amount such as 5 cm at 100 m or 10 cm at 100 m, etc. A shooter can zero-in his rifle by first firing a set of test shots to determine how far off the bullets hit from the desired point of impact. He then selects one or more wedge prisms supplied with the riflescope and attaches them to the front (objective side) of the riflescope. The wedge prisms shift the riflescope's point of aim and bring it in alignment with the rifle's point of impact.

Abstract: A fire-control system including a housing, a light channel, a light source, and a processor. Through the light channel, a user may directly observe a target and receive visually displayed information simultaneously. The light channel includes partially reflective optics and allows for visualization of a reticle to the user via the partially reflective optics. A measure of the distance to the target is also received by the system. The processor is for determining the adequate position of the reticle, based on the distance to the target, and for controlling the light source to emit light so that the reticle is visualized at the adequate position. The light source is an array capable of selectively emitting light in well defined locations on its surface.
