    Abstract: A blower assembly for an airflow medium, such as in a heating, ventilation, and air conditioning (HVAC) system. The blower assembly has a case defining an airflow inlet and an airflow outlet. An airflow generator is mounted within the case. Rotation of the airflow generator draws airflow into the case through the airflow inlet, directs airflow through the case, and pushes airflow out of the case through the airflow outlet. The motor is entirely within the case and is mounted on an upstream side of the airflow generator with respect to direction of airflow produced by the airflow generator through the case.

    Abstract: A sound damper and associated system are disclosed for damping sound. In embodiments, the sound damper is utilized within an automotive HVAC system. A passage wall defines an air passageway that transmits air. The sound damper includes a micro perforated panel (MPP) located within an opening formed into a passage wall. A back wall is spaced from the MPP, and a cavity is provided between the back wall and the MPP that is outside the air passageway. In embodiments, the MPP can be covered by a non-perforated film that is acoustically transparent and air impermeable.

    Abstract: An active grill shutter assembly including a plurality of airflow control blades. At least two of the airflow control blades have different curvatures or chord lengths configured to optimize airflow over a curvature of an air duct that the active grill shutter is mounted in. An actuator is linked to the plurality of airflow control blades with a linkage assembly to rotate the plurality of airflow control blades.
