Abstract: A flush-mounted, in-ceiling exhaust fan grille for attachment to an exhaust fan housing includes a planar integration flange forming a perimeter of the grille. The integration flange includes a plurality of through holes along the perimeter. An insert may be configured for insertion within the perimeter of the integration flange. A light module may be configured to join within a central portion of the insert while maintaining an opening between an entirety of the light module and the insert. At least one spring may be attached to the insert on a first end and attached to the fan housing on a second end, wherein the at least one spring applies a force drawing the insert towards the fan housing. An exhaust fan may be provided to draw air into the fan housing through the opening between the light module and the insert to be exhausted for proper ventilation.

Abstract: A ventilation assembly having a moveable trim moveable between an open position in which the moveable trim defines a gap with a ceiling trim to allow movement of fluid and a closed position in which the moveable trim is against or adjacent to the ceiling trim to eliminate or reduce the gap and prevent or limit fluid flow.

Abstract: A combined ventilation and illumination system includes a ventilation assembly, a light fixture assembly, and a connector assembly. In an installed position, the system is installed above a ceiling of a room of building structure (e.g., a residence or workplace) to provide ventilation for the room. The system couples a light fixture to ventilation assembly below the ceiling. In the installed position, an air flow cavity is defined between the light fixture and the ceiling, where the cavity allows for air flow around the light fixture and into the ventilation assembly for eventual exhaust beyond the room in which the system is installed. The cavity includes a first critical distance that is sized according to operating parameters of a blower of the ventilation assembly to provide an adequate flow rate of intake air and to provide acceptable sound levels during operation of the system.

Abstract: A ventilation device having a housing defining an outlet, a first inlet configured to be in fluid communication with a first room of a building structure and a second inlet configured to be in fluid communication with a second room of a building structure. A blower is located within the housing to move air from the first and second inlet to the outlet. A first damper is located adjacent the first inlet and configured to be operable between a closed position blocking fluid communication between the blower and the first inlet and an open position allowing fluid communication between the blower and the first inlet. A second damper is located adjacent the second inlet and configured to be operable between a closed position blocking fluid communication between the blower and the second inlet and an open position allowing fluid communication between the blower and the second inlet.

Abstract: An outdoor repellant system for providing an insect controlled region at a home, restaurant or business. The repellant system includes a plurality of repellant devices, wherein each repellant device includes a fixture, a support member and a stake configured to be inserted into a support surface, such as the ground. The repellant device also includes a device wire that extends through the fixture, the support member and the stake. The device wires are coupled by a connector with an internal adaptor to a main power line that is routed along the support surface and electrically connected by a programmable controller to a primary power source. The fixture includes a number of internal components, including a volatilizing unit that ensures the proper disbursement of repellant through the fixture to provide the insect controlled region.
