Abstract: Disclosed are methods, systems and computer program products for producing and applying a spray foam producing mixture onto a surface, and imaging a spray cone, or the applied surface, using an infrared or an optical imaging device to capture an image, and then determining, based on the captured image, if a defect that requires correction exists in the spray cone or in the applied surface; and optionally, in response to determining that a defect requiring correction exists, modifying a process parameter in producing or applying spray foam.

Abstract: An acoustical barrier (10) for a vehicle having a barrier wall which includes a floor area (23) and a fire wall area (25) extending between a wheel well area (41) and a drive train area (42). The acoustical barrier (10) includes a mass layer (12) that covers at least a portion of the barrier wall. The mass layer (12) has an inner surface (16) that faces the barrier wall with an integrally formed peripheral rib (52) projecting therefrom. A first set of elongate ribs (48) intersects and joins with a second set of elongate ribs (50). The first and second sets of elongate ribs (48, 50) are located within the enclosed area. Each elongate rib (48, 50) includes an upper portion integrally formed with the inner surface (16) of the mass layer and a lower portion with an outer edge (54, 60) adapted to at least face the barrier wall.
