Abstract: A diffusing vent assembly may include a diffuser base and a diffusing head. The diffuser base may include a mounting flange, a collar extending from the mounting flange, and a ductwork fixation channel. The collar may span an infra-ceiling space of a vehicle. The diffusing head may include a diffuser vane configuration, a rotational flange surrounding the diffuser vane configuration, and an air blade. The diffuser base and the diffusing head further comprise complementary rotational securement members that permit rotation of the diffusing head relative to the diffuser base. The air blade may extend through the collar of the diffuser base. Installing the diffusing vent assembly may include engaging the ductwork fixation channel with a supply duct, inserting the diffusing head into the diffuser base, and securing the diffusing head and the diffuser base using the complimentary rotational securement members.

Abstract: A laminated panel is provided comprising a skeletal framework, foam core inserts, an impact resistant sheet, and a weather resistant sheet bonded together with adhesive. Recreational vehicles incorporating such panels are also contemplated, as are methods of making the composite laminated panel.

Abstract: A composite floor is provided comprising a skeletal framework, foam core inserts, an impact resistant sheet, and a weather resistant sheet bonded together with adhesive. Recreational vehicles incorporating such floors are also contemplated, as are methods of making the composite floor.

Abstract: Recreational vehicles are provided with a tapered duct connector and/or a conditioned air receiving sleeve that is positioned in an infra-ceiling space of the vehicle. The tapered duct connector comprises a connector inlet coupled to a conditioned air passage on a wall of the conditioned air receiving sleeve, and a connector outlet coupled to the supply duct, to fluidly couple the sleeve to the supply duct. The tapered duct connector comprises a transitional duct height that increases from the connector outlet to the connector inlet. The conditioned air passage of the conditioned air receiving sleeve, the tapered duct connector, and the supply duct is contained such that air can pass from the conditioned air opening of the conditioned air receiving sleeve, through the conditioned air receiving sleeve, and into the supply duct without contacting structural components in the infra-ceiling space of the recreational vehicle.

Abstract: A system for the automatic deployment of traffic control signs during a power outage which enhances public safety, automatically deploys in the event of power outage, can be placed in a plurality of roadway intersections and structures, provides an alternative means to deploy safety and other information, and eliminates driver confusion when deployed. The system essentially comprises a traffic control sign that is bisected and having a top half portion and a bottom half portion connected by a hinge means, an electromagnet attached to the approximate center of the top half portion front surface, an armature plate attached to the bottom half portion front surface, an attaching means attached to the top half portion back surface for affixing the system to a structure in an environment, and at least one power cable extending from the electromagnet and connecting to a powering means in the environment.
