Abstract: A lens cover apparatus comprises a mounting structure, a lens cover, a pivot joint structure, and a spring. The mounting structure is configured for securing the lens cover apparatus to a support structure. The pivot joint structure is coupled between the mounting structure and the lens cover and configured for allowing multi-axis articulation of the lens cover with respect to the mounting structure. The spring is coupled between the pivot joint structure and the lens cover. The spring and the pivot joint structure are jointly configured for causing spring-biased multi-axis articulation of the lens cover between a use position thereof and a stowed position thereof in response to manual initiation of the articulation.

Abstract: A targeting apparatus for a gun comprises a mirror assembly, a mounting base and a sighting device. The mirror assembly includes a single utilized mirror having a target imaging surface. The mounting base has the mirror assembly moveably attached thereto. The single utilized mirror is movable between a sighting device use position thereof with respect to the mounting base and a mirror use position thereof with respect to the mounting base. The sighting device is attached to the mirror assembly. The sighting device includes a sighting member configured for being aligned with a mating alignment member of a companion sighting device when the single utilized mirror is in the sighting device used position thereby enabling precision aiming through combined use of said sighting devices. The sighting member is independently adjustable for windage and for elevation.

Abstract: A sighting device includes an aperture body having a sighting aperture therein. The sighting aperture includes four intersecting sides that jointly define horizontally opposing corners. A horizontal reference axis of the aperture body extends through the horizontally opposing corners such that a first pair of the sides are entirely above the horizontal reference axis and a second pair of the sides are entirely below the horizontal reference axis. The first pair of the sides define a corner vertically offset above the horizontal reference axis and equidistant between the horizontally opposing corners. The first pair of the sides are of approximately equal length.

Abstract: Offset opening tabs for zippered plastic bags and a variety of disposable and reusable containers which make opening a container fast and easy, as well as solving the difficulties experienced by diverse types of users who have functional or situational finger dexterity limitations or compromised vision that make opening packages a cumbersome or frustrating event.

Abstract: A single-mirror target viewing apparatus configured for enabling a gun to be fired at a desired target from a cover position in an aimed manner. The target viewing apparatus comprises a mirror assembly, a mounting base and a sighting device. The mirror assembly includes a single utilized mirror that provides a target imaging surface. The mounting base is configured for being attached to a gun and having the mirror assembly moveably attached thereto. The single utilized mirror is movable between a stowed position and a deployed position and is rotatable between a plurality of rotational positions when in the deployed position. The sighting device is attached to a non-viewing portion of the mirror assembly.

The mounting base is configured for being attached to a gun and having the mirror assembly moveably attached thereto. The single utilized mirror is movable between a stowed position and a deployed position and is rotatable between a plurality of rotational positions when in the deployed position. When in the at least one of the rotational positions, the target imaging surface is in a skewed orientation with respect to at least one of a longitudinal axis of a barrel of the gun and an axis that extends generally perpendicular to the longitudinal axis of the gun barrel.

Abstract: A single-mirror target viewing apparatus configured for enabling a gun to be fired at a desired target from a cover position in an aimed manner. The target viewing apparatus comprises a primary mirror assembly, a mounting base and an auxiliary mirror assembly. The primary mirror assembly includes a single utilized mirror that provides a target imaging surface. The mounting base is configured for being attached to a gun and having the primary mirror assembly moveably attached thereto. The single utilized mirror is movable between a stowed position and a deployed position and is rotatable between a plurality of rotational positions when in the deployed position. The auxiliary mirror assembly is removably attached to at least one of the primary mirror assembly and the mounting base. The single utilized mirror of the primary mirror assembly is a first configuration and the auxiliary mirror assembly includes a mirror of a second configuration different than the first configuration.
