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 diagnostic device includes a sensor stack with multiple panels of a porous material disposed in planes parallel to one another and in face-to-face contact with each other. At least a portion of the panels of the porous material include hydrophobic regions and hydrophilic regions configured to provide a sample flow path for migration of a fluid sample through the sensor stack from one panel to another in the hydrophilic regions. A wicking layer is on a major surface of the sensor stack.
