Abstract: An adjustable aperture axis peep sight device is disclosed with an outer ring having a first axis, and an inner body member having a second axis. The first axis of the outer ring forms a sight angle with the second axis of the inner body member. A first partially spherical surface is formed on the outer ring. A second partially spherical surface is formed on the inner body member. The first partially spherical surface movably mates with the second partially spherical surface. The sight angle is adjustable by moving the inner body member relative to the outer ring.

Abstract: An arrow rest device is disclosed. The example arrow rest device includes A mounting bracket for attachment to a bow riser. The example arrow rest device also includes a geometrically shaped surface of the mounting bracket. The example arrow rest device also includes a coupler having a mating attachment surface for connecting with the geometrically shaped surface of the mounting bracket. The example arrow rest device also includes an accessory for attachment to the coupler, and an opening formed in the accessory. The example arrow rest device also includes a shaft received through the opening formed in the accessory. The shaft is rotatable in the opening formed in the accessory. The shaft has a first end to accommodate an arrow launcher, and a second end to attach to a cord.

Abstract: An example archery arrow rest orthogonal cord force device for an arrow rest of an archery bow includes a housing member having a first end and a second end. A circuitous path is formed at least partly within the housing member. The circuitous path extends at least partly between the first end and the second end of the housing member. The housing member is attached along a linear axis of a cord defined by two attachment points of the cord in the arrow rest as part of the archery bow.

Abstract: An arrow rest device is disclosed. The example arrow rest device includes a geometrically shaped mounting bracket. The example arrow rest device also includes a coupler for connecting to the geometrically shaped mounting bracket. The example arrow rest device also includes a base of the coupler, the base having a parallel clamp with two components. The example arrow rest device also includes a plank member that is perpendicular to the base. The example arrow rest device also includes a coupling mechanism that positions the coupler relative to the geometrically shaped mounting bracket.

Abstract: A device is disclosed for measuring arrow position or location at rest. An example device includes a platform that mounts to an archery bow system to determine a position of an arrow shaft in relation to an inside of a riser shelf of the archery bow system for tuning or data collection. The example device also includes a first slot in the platform. A center shot indicator adjacent to the first slot references the center shot of the arrow shaft. A measurement reference is slidable, separately, in the first slot to reference center shot of the arrow shaft.

Abstract: An archery viewfinder is disclosed. An example archery viewfinder may include a viewfinder housing having a cylindrical shape. The viewfinder may be mounted on one or both of a front toward target position and a rear toward user position in an archery bow system. The archery viewfinder may also include at least one light baffle in the viewfinder housing. The at least one light baffle is formed by a first diameter of the viewfinder forming adjacent ridges and a second diameter of the viewfinder housing forming a groove between the adjacent ridges. A combination of the geometrically parallel shape and the at least one light baffle substantially reduces or even fully eliminates incident stray light from causing glare when viewed or observed by the user.

Abstract: A tapered arrow launcher is disclosed as it may be implemented with an arrow launch platform (or arrow rest) for an archery bow. An example tapered arrow rest launcher may include an arrow support end, and a mounting end. The arrow support end of the arrow rest launcher is thinner than the mounting end, resulting in a thickness that is tapered along one or more sections. With this arrangement, fatigue forces and work hardening forces do not concentrate at the mounting end of the tapered arrow launcher when arrows are launched with the arrow launch platform.

Abstract: A shooting sports sight apparatus to inhibit unwanted stray light of an observable scene. An example apparatus comprises a sight housing having a first end, a second end, an outer surface, and an inner surface. At least one concentric ring is positioned between the first end and the second end. At least one annular groove is defined between the first end of the sight housing and the concentric ring. The concentric ring provides a surface for stray light photons entering the first end of the sight housing to bounce in directions generally away from the line of sight into the annular groove, thereby inhibiting the stray light photons from entering field of regard (FOR) photons reaching the aft end of the sight housing which make up the observable scene where the second end has means for changing the baffle aperture diameter forming the final light baffle of the baffle assembly.

Abstract: A 1/4 wave circuit switch for use in an NMR probe has a housing with a stepped cavity for precisely locating switch components inside. The 1/4 wave circuit switch cooperates with a 1/4 wave tube and is designed to receive either an external capacitor on a capacitor stick for single tune operations or a 1/4 wave center conductor with a threaded tip on a 1/4 wave stick for double tune operations. For single tune operations, the external capacitor comes into contact at one end with a resiliently supported, movable electrical contact and at the other end with a spring clip inside the housing cavity to orient the external capacitor in parallel with the NMR coil. The movable electrical contact is resiliently biased by a pair of crescent washers supported by an insert plug which serves as a positive stop for the travel of the electrical contact.
