Abstract: A vision testing apparatus has a frame including a face plate with at least one eye shield having a viewing slot positioned in a viewing direction perpendicular to the face plate, at least one variable lens element including an outer rail and multiple regions of varying diopter power having a width that is equal to or greater than the width of the viewing slot of the eye shield, and adjustable controls for moving the variable lens element in a direction perpendicularly to the viewing direction along a plane of the face plate. The testing apparatus is portable and can be used in developing nations where visual acuity is not corrected because of lack of access to optometric care.

Abstract: An electrical outlet box assembly including an outlet box and a lid. The outlet box generally includes a base, an outer wall parametrically bounding the base and extending upwardly therefrom forming a box interior, the outer wall having an upper and lower end, the upper end forming a lip which defines an opening to the box interior. The assembly further includes a lid. The lid has a closed position such that when the lid is in the closed position the opening to the box interior is partially covered forming a receptacle opening having a size substantially similar to an opening of a standard size outlet box. The lid further includes an open position such that when the lid is in the open position, the opening to the box interior is entirely uncovered thereby permitting unrestricted access into the outlet box interior.

Abstract: An electrical junction box assembly for accommodating an electrical cable inserted therein. The assembly includes a junction box and a cable clamp. The junction box includes a back wall and a side wall which perimetrically extends from the back wall to define an open end opposite the back wall. The junction box further includes a cable entry opening in the side wall for permitting insertion of the cable thereinto. The back wall further includes a cable clamp mount positioned adjacent the cable entry opening. The cable clamp mount has a clamp insertion surface positioned substantially orthogonal to the cable entry opening. The clamp insertion surface defines a cable clamp insertion aperture into which the cable clamp is manually removably insertable. The cable clamp includes a deflectable cable engagement arm spaced adjacent from the cable entry opening of the side wall of the junction box.
