Abstract: An airborne particle collection system includes an airflow directing unit, register units, a fan unit, and a control system. The airflow directing unit includes a plurality of separately controlled air distribution segments. Each register unit includes a motorized damper and filter. The fan unit is connected to the airflow directing unit and to the register units through piping. The fan unit injects air into the airflow directing unit, and generates a vacuum force that causes exhaust air with airborne particles to be pulled into the register units and filtered by the filters within the register units. The control system selectively controls the air distribution segments of the airflow directing unit and the motorized dampers of the register units to generate alterable airflow patterns between the airflow directing unit and the register units in different zones within a room in which the airflow directing unit and the register units are disposed.

Abstract: A goose neck style vent has a base that registers with a surface opening of a building, and upstanding walls which form a portion of a curved air flow pathway above the vent opening.
