An assembly allowing a user to adjust a relative positioning of an imaging portal of a lens attached to an electronic device relative to the viewing portal of a lens of an optical device. The assembly is made up of a planar adjustment unit having multiple plates that frictionally interface with one another such that they allow movement by a user. The components of the planar adjustment unit are held together by at least one elastically deformable element that passes through the channels in the sliding plates of the planar adjustment unit. The at least one elastically deformable element holds the planar adjustment unit together in tension such that the assembled plates may still slide with respect to one another, but remain in place by static friction when not moved by a user. The planar adjustment unit may be further combined with components allowing for three-dimensional adjustment of an imaging portal of a lens attached to an electronic device relative to a viewing portal of a lens of an optical device.

New systems, hardware and methods for extremely precise aiming and shooting of firearms by relatively unskilled users are provided. In some embodiments, shots may be planned in advance and rapidly carried out. A specialized control system comprising computer hardware allows a user to plot a planned shot or shot sequence with indicators on a site display, evaluate the accuracy of the planned shot(s), adjust the location of the shot(s), and then shoot. In some embodiments, the system may counteract and otherwise adjust for certain ballistic and other accuracy-impacting factors with a position-actuable firing mechanism to maintain a projected flight path of such a point of impact at all times. The system is unobtrusive, allowing users to engage ordinary targeting activity, including ordinary firearm aiming movements. In some embodiments, aiming and execution aspects of the invention are adapted to non-lethal measures, which may be assigned by the system autonomously.

A chronograph system with a frame, at least two sensors, and a computing device. The frame is configured to removably couple to a barrel of a firearm. The sensors are attached to the frame and are configured to detect a projectile as the projectile passes each sensor. The chronograph system is configured to use data received from the at least two sensors regarding each projectile to determine a velocity of each projectile and create velocity data based on the velocity of each projectile. The computing device is configured to communicatively couple to the chronograph system and display the velocity data to a user of the firearm.

A wearable electronic device displays an impact location that shows where a projectile fired from a weapon will hit a target and displays a bullseye location that shows a desired location where to hit the target. The wearable electronic device indicates firing the weapon when the impact location overlaps with the bullseye location.

A method of permanently affixing tungsten cube fragments to the fragmentation warhead in a convex Claymore mine having a plastic case and a housing. Pieces of predetermined sized structural film adhesive are positioned at temperature 60 F.5 F., then pressed into the plastic case while pouring tungsten cubes into the case. The cubes are arranged into desired patterns all at temperature 70 F.2 F. An interface plate and 5 lbs of weight are then placed atop thereof and all are heated in an oven at temperature 205 F.5 F. for four hours for full cure of a desired product.

Systems, devices, and methods for determining a time of flight (TOF) of a first bullet fired from a gun to pass a target plane of a target; determining a location of an aimpoint on the target in an imager field of view (FOV) relative to a disturbed reticle at a time the first bullet is fired by the gun; determining a location of the first bullet relative to the location of the aimpoint on the target at the TOF in the imager FOV; and determining an updated location of the disturbed reticle based on a difference between the location of the first bullet and the location of the aimpoint on the target at the time the first bullet crosses the target plane and a difference between the location of the disturbed reticle and the location of the aimpoint on the target at the time the first bullet was fired.

A firearm accessory is rotatable on two axes via a sleeve mounted on a bearing comprising a first and a second part, the second part being rotatable and coupled to the first part and facilitating a central opening and a first rotational motion and protrusions with at least one hinge from the sleeve attaching to a mirror device acting as a second rotational motion. An alternative teaches digital control of a swinging mirror assembly having spring acting ball actuators providing the digital action between the actuators and a surface. In another alternative, two armatures also are taught that connect a reflective device to a bearing mounted sleeve in front of or behind a target viewing device. These may be directly rail mounted with appropriate attachment devices or directly connected to or manufactured as an integral part of a reflex sight, night vision, scope or similar viewing system of a firearm.
