Abstract: The embodiments provide a system and method for filtering out smoke and/or toxic gases/fumes from air in a building. The system integrates various smart devices with an HVAC system along with a controlling software application that can change the state of the smart devices, thereby controlling the types and quantities of air moving through the HVAC system at any time. In particular, the system can adjust the openings of one or more smart registers to control how much air passes in and out of the HVAC system over a given period of time. The system can also adjust the opening of a smart intake vent to control how much fresh (outside) air passes into the system over a given period of time. The system can also adjust the opening of a smart furnace valve that is disposed within the furnace.

Abstract: An air vent is configured to discharge two separate volumetric flows of air in respectively different and intersecting discharge directions. A perceived air discharge direction is adjustable with no change to the intersecting discharge directions. A first volumetric flow of air exits the first air duct in a first direction, and a second volumetric flow of air exits the second air duct in a second direction that intersects the first direction so that the volumetric flows of air collide after exiting airducts of the air vent. A non-visible vane located along one of the air ducts is moveable to change the perceived air discharge direction.

Abstract: A solar-powered vehicle interior temperature management system includes a flexible sun blocking textile configured for mounting on a vehicle's interior windshield surface, with integrated photovoltaic panels on its outward-facing surface. The system includes a spring roller mounting mechanism at the windshield's upper edge and fasteners at the lower edge for dashboard attachment. An enclosure mounted adjacent to the spring roller houses rechargeable batteries and squirrel cage fans. The photovoltaic panels collect solar energy and charge the batteries through a charge controller. When activated via a power switch, the fans create air movement to cool the vehicle interior. The entire system mounts on the interior side of the windshield, protecting components from weather and vandalism while requiring no permanent vehicle modifications. The flexible textile construction allows the system to be rolled for storage when not in use, while maintaining solar charging capability during deployment.

Abstract: Many import and export regulations require fumigation of goods, such as products or commodities, to ensure that non-native pests are not introduced. The fumigating process can involve placing the goods in a sealed containment system, and introducing the sealed good to a fumigant, such as methyl bromide gas, for a predetermined amount of time. After fumigation, regulations may require how to dispense the fumigant. The fumigant can be exhausted through fans, baffles, dampers, filters, and a chimney, as part of an emission system, in a controlled manner. The controlled manner can include combining the fumigant with ambient air and releasing or exhausting the combination over an amount of time, which mitigates pollution by the fumigant. The time-period is not specific, and instead is the time needed to meet regulatory requirements.
