Abstract: This invention provides a hanger for supporting pictures, mirrors or other objects on a wall. Specifically, this invention allows a person to nail the hanger to the wall and if relatively minor adjustments are needed, to remove a screw cap on the nail, remove the hanger and reattach the hanger to the wall using another hole on the hanger that best approximates the desired position, then put the cap back on the nail and screw the cap tight. In another embodiment, spacers can be attached to the hanger so that additional hangers can form a larger hanger and then placed back on the wall through the nail already in place that best approximates the position. Additional nails can then be inserted into some of the other hanger's holes to provide additional support, strength and leveling.

Abstract: This invention provides a noise reduction system for in-wall HVAC systems. The noise reduction system can be constructed as a box structure that can be attached to an exterior wall of a dwelling where the box structure overlaps the intake air vent and the exhaust air vent of the in-wall HVAC system. For new or remodeled construction, the noise reduction system may be built into the dwelling's exterior wall so that the amount of noise reduction system's protrusion beyond the flat surface of the exterior wall is minimized. For additional noise reduction, the noise reduction system can incorporate active and/or passive noise reduction features.
