Abstract

An optical sighting device includes an eyepiece positioned to receive optical radiation along an optical axis to produce a real exit pupil located remote from the eyepiece. The real exit pupil is positioned at an eye relief distance from the eyepiece along the optical axis. A digital signal processor determines an axial distance from the eyepiece to an eye positioned proximate the real exit pupil along the optical axis. An aperture stop is centered along the optical axis to direct the optical radiation in a direction of the eyepiece. The eye relief distance is based at least in part on a position of the aperture stop along the optical axis. The optical sighting device further includes an eye relief actuator to translate the aperture stop along the optical axis to null a spatial offset between the eye relief distance and the axial distance to the eye.

Abstract

A spring damper device comprising a directional spring having first and second ends, and defining an inner diameter region. A damper (e.g., viscoelastic polymer slug) comprising an element of elasticity configured to be situated within the inner diameter region of the directional spring. In response to a load on the spring damper device, the directional spring operates to compress, and the damper operates to dampen vibration associated with the load. The damper can comprise a viscoelastic damper comprising both an element of viscosity and the element of elasticity. The damper can be substantially coaxially aligned with the directional spring. Spring damper device(s) can be preloaded in a micro adjustment mechanism to account for positional adjustments between two structures (e.g., between a scope and a firearm), such that the spring(s) attenuate a shock impulse event (e.g., when firing), while the damper(s) attenuate vibration (e.g., to prevent damage the scope).

Abstract

A gun sight clamping system utilizes a resilient device and an over-center cam to attach a gun sight to the rail of a gun. The body of the clamping system is clamped to the rail using a clamping mechanism on one side of the assembly and a resilient device on the other side of the assembly. The resilient device operates in a direction parallel to the clamping direction. A cross bar connects the clamping mechanism to the resilient device and provides a means to squeeze the body of the mount to the rail. As the !ever is closed, the cam drives the cross bar, pulling the clamping mechanism against the rail. The resilient device allows the cam to move to an over- center position wherein the unit resists loosening during operation. Once the over- center position is achieved, the spring force of the resilient device holds the cam in the closed position.
