Abstract: An aerosol collection system and method. The system includes a bio-aerosol delivery device configured to supply bioparticles in a gas stream, a moisture exchange device including a partition member coupled to the gas stream and configured to humidify or dehumidify the bioparticles in the gas stream, and an aerosol collection medium downstream from the moisture exchange device and configured to collect the bioparticles. The method includes delivering bioparticles in a gas stream, humidifying or dehumidifying the bioparticles in the gas stream by transport of water across a partition member and into a vapor phase of the gas stream, and collecting the bioparticles by a collection medium.

Abstract: A building automation system for controlling air quality of an environment inside a building. The system has at least one bioaerosol detector disposed in at least one location inside the building for detection of bioaerosols circulating inside the building, and has a processor in communication with the bioaerosol detector, and configured to a) determine when one or more thresholds of a bioaerosol has been detected, and b) activate building mitigation resources to reduce a level of the detected bioaerosol.

Abstract: Sample monitoring and flow control systems and methods are disclosed for monitoring of airborne particulates. A system may include a particle collection filter. The system also includes a fluid moving device for moving a sample through the particle collection filter. Further, the system includes a light source configured to direct irradiating light towards the particle collection filter. The system also includes a light detector positioned to receive the irradiating light passing through the particle collection filter and configured to generate a signal representative of an amount of the received light. Further, the system includes a controller configured to receive the signal and to control the fluid moving device based on the amount of the received light.

Abstract: An optical system for particle detection. The system includes a sample inlet housing; a sample outlet housing; a detection cavity having an axially surrounding wall and disposed between the sample inlet housing and the sample outlet housing; a light source configured to irradiate light through the detection cavity to particles of a sample fluid flowing inside the wall of the detection cavity; a light detector for detecting the light that is scattered by particles of the sample fluid in the detection cavity; an alignment rail having a base and sidewalls which a) extend from the sample inlet housing to the sample outlet housing and b) connect the sample inlet housing to the sample outlet housing; and the alignment rail comprising a channel formed by the base and the sidewalls, the channel having a channel lateral width fitting to a housing width of at least one of the sample inlet housing and the sample outlet housing, whereby the sample inlet housing, the housing, and the sample outlet housing are held in alignment together.

Abstract: A filtration device including a contoured support having 1) an interior surface, 2) an outside peripheral surface spaced farther from a center of the contoured support than the interior surface, and 3) a rim enclosed and sealed to a perimeter of the contoured support. The filtration device includes macroscopic openings in the contoured support extending from the interior surface to the outside peripheral surface, and a plurality of nanofibers having diameters less than 1 micron. The nanofibers are disposed on the outside peripheral surface of the contoured support, and cover the macroscopic openings to form a filtration medium on the contoured support.
