Abstract: An assembly includes an enclosure including first and second regions spaced apart along a first direction, and a plurality of spaced apart acoustic baffles arranged along a second direction different from the first direction and disposed in the enclosure between the first and second regions. The plurality of spaced apart acoustic baffles includes adjacent first and second acoustic baffles. Each of the first and second acoustic baffles include an acoustically absorptive layer disposed on a sheet having a specific airflow resistance greater than 200 MKS Rayl. The first and second acoustic baffles define a channel therebetween. At least a portion of the channel extends along a longitudinal direction making an oblique angle with the first direction.

Abstract: A contactor system includes a plurality of contactor panels. Each contactor panel includes a frame member and a membrane array adapted to be received within the frame member. The membrane array defines a first end portion, a second end portion, and a plurality of hollow fibers. The contactor system also includes a first manifold in selective fluid communication with the first end portion of the membrane array of each contactor panel. The contactor system further includes a second manifold in direct fluid communication with the second end portion of the membrane array of each contactor panel. The contactor system includes a controller configured to provide selective fluid communication between the first manifold and the first end portion of the membrane array of each contactor panel.

Abstract: A contactor module for a contactor panel includes a frame member and a contactor media coupled to the frame member. The contractor module defines a first side and a second side. The contactor media includes at least one first membrane array including a plurality of first hollow fibers extending along a first fiber axis. The at least one first membrane array defines a first axis. Further, the contactor module includes at least one second membrane array including a plurality of second hollow fibers extending along a second fiber axis. The at least one second membrane array defines a second axis. The at least one first membrane array and the at least one second membrane array is disposed such that a first inclination angle is defined between the first axis and the second axis. Moreover, the first inclination angle is greater than zero degree and less than 180 degrees.

Abstract: A film stack reflects incident light in some areas and transmits incident light in other areas, and it redirects incident light with one or more structured surfaces. The spatially variable reflection and transmission is achieved at least in part with reflective strips, and the reflective strips are attached to a first major surface of a structured optical film in the film stack. A second major surface of the structured optical film, opposite the first major surface, attaches to a substrate. The reflective strips attach to the structured optical film by a first discontinuous adhesive layer, having first adhesive areas. The structured optical film attaches to the substrate by a second discontinuous adhesive layer, having second adhesive areas. A major portion of the first adhesive areas, and a major portion of the second adhesive areas, is circumscribed by the reflective strips. The film stack may be part of a light duct.
