Abstract: A sports figure shaped fan for ventilation grills comprising a caricature formed in the shape of a sports figure. The fan is attached to a ventilation grill and the arms are extended and rotate when subjected to a back draft from the air flow of the ventilation system. The rotation mimics a throwing action of the sports figure. The fan also includes a reservoir and access to the reservoir for inserting one of a scenting agent, a deodorizing agent and a combination thereof, in the reservoir located in a designated portion of the caricature. The designated portion of the sports figure caricature is sufficiently permeable on either side of the reservoir so that a vapor is dispersed by the movement of the air flow. Another embodiment includes the lighting of a portion of the sports figure when a telecommunication signal is received by a cell phone.

Abstract: Air duct outlets provide automatic oscillation of air flow and also allow users to manually redirect air streams. An air duct outlet includes a housing having an air passageway that terminates at an air outlet. A drive source is operably connected to a reciprocating member and transmits reciprocating motion to the reciprocating member. An air-directing vane is pivotally attached within the air passageway and is movable within a range of positions to direct an air stream flowing through the air passageway and exiting from the outlet. An actuator extends from the housing and is movable between first, second and third positions. A user can manually pivot the air-directing vane via movement of the actuator between the first and second positions. When the actuator is moved to a third position, the reciprocating member operably engages the drive arm and causes the air-directing vane to oscillate automatically.

Abstract: In an air passage switching device, a flexible film moves to traverse an air passage of an air duct, thereby switching and controlling a communication state of the air passage. A thickness t of the film, a glass transition temperature Tg thereof and a radius of curvature r thereof are set so that a relationship expressed by a formula of t≦(0.00578×Tg0.448×r0.333) is satisfied and a bending stiffness of the film is set equal to or higher than 1 &mgr;N·m2. Accordingly, the film can be restricted from being buckling-deformed and from being damaged. As a result, an air leakage amount from a clearance between the film and the air passage due to the deformation can be effectively restricted.

Abstract: A vent device for overcoming the problem of moisture accumulating within a wall structure. The vent device promotes air and moisture circulation within the wall structure by having a channeling plate with a plurality of vertically oriented channels. The vent device also has a support flange adjoined to the channeling plate. The vertically oriented channels define a passageway for air and water to travel along when the vent device is disposed within the wall structure. The channeling plate is adapted for being positioned between a horizontal joist and a wallboard of the wall structure. When the vent device is positioned within the wall structure, the passageway allows air and moisture to travel between the horizontal joist and the wallboard.
