Abstract: A sliding plate air damper allows control over air flow with the sliding plate having a range of positions which do not change the total area of the orifices through the damper. Openings through the fixed plate and the openings through the sliding plate can each make up about 70% of the active area of each plate. The slide plate can be slid to a position where its webbings divide each fixed plate opening into two orifices for air flow. The air flow can be controlled by selecting the slide position of the webbings from a most restrictive position in which the webbings are in the middle of fixed plate openings, through a range of positions where the orifice on one side of the webbing is larger than the orifice on the other side of the webbing, to a maximally opened position where the webbing on the slide plate overlies the webbing on the fixed plate.

The vent assembly includes at least one vane positionable to aim airflow into the passenger compartment in differing airflow directions. The positioning device is connected to the vane. The controller is configured to operate the positioning device to re-position the vane from aiming the airflow in a first airflow direction to aiming the airflow in a second airflow direction in response to the controller determining via signals from the motion sensor that the vehicle is changing direction of movement.

Abstract: A system for mitigating the flow of vapors from contaminated soil into a building has a blower pulling an exhaust from underneath the sub slab of the building and blowing the vapors away from the building. The blower is controlled by pressure sensors that measure the pressure drop across the sub slab. The sensors are monitored to make sure they all have a minimum pressure drop. If any of the sensors has an inadequate pressure drop, the blower speed is increased by a small amount. If all of the sensors have adequate pressure drop, then the blower speed is decreased by a small amount. The system then rechecks the pressure drops on a periodic basis and makes appropriate blower speed adjustments after each measurement.

Abstract: Improvements in an outside house vent that blocks embers, water and rain that can cause damage to a house of building. The prevention of fire and ember intrusion into a building prevents fires in homes where invalids and children are left alone. The prevention of water into structure further reduces the potential for mold growth in the attic or walls of a home or structure. The filtering further prevents intrusion of creatures such as but not limited to bugs, insects, bees, wasps, animals, critters and other flying and crawling animals from entering the building. The vent is a fireproof set of louver or filter pads with fire arresting screens that is passed through a wall that vents into the building. The vent can be installed on old and new construction to provide improved fire prevention, increase the value and salability in fire prone areas.
