Abstract: An improvement to an optical assembly that is adapted to accept light from a field of view in front of the optical assembly and create a first inverted image on a first image plane. Further the assembly includes an objective lens, a first prism adapted to receive light from the objective lens and a second prism, adapted to receive light from the first prism and emit light. The improvement is the addition of a negative lens interposed between the first prism and the second prism, thereby reducing the total optical pathway of the optical assembly, relative to a device performing the same optical function and lacking the negative lens.

Abstract: Embodiments of a limb retainer system to secure bow limbs to a riser on an archery bow. The limb retainer system includes a first part and a second part that are disposed, respectively, on a front and a back of the riser to position the limb elements to retain a shooting string under tension. In one embodiment, the first part secure the limb elements in position on the riser. The second part is configured to rotate relative to the first part, thereby allowing an end user to adjust the tension of the bowstring. This configuration offer a robust, cost effective design that prevents unwanted movement of the bow limbs and preserves adjustment necessary for adequate tuning of the archery bow.

Abstract: A rifle scope, comprising: a scope housing and an optical train, supported in the scope housing and defining an optical axis having a pointing direction. Also, a pointing angle adjustment electrical user input device includes a first button having a first position that does not cause the pointing angle to change, and a second position that causes a progressive change in the pointing angle over time in a first direction. The user input device also includes a second button, also having a first position and a second position and wherein placing the second button in the second position causes the pointing angle to change over time in a second direction opposite to the first direction. Finally, the rifle scope includes an electric actuator, adapted to change the pointing direction, responsive to the user input device.
