Abstract: System for detecting and analyzing particles in an air stream includes an inlet, a particle concentrator and a particle discriminator having an air channel with a cross-sectional geometry that changes within at least one of the inlet, particle concentrator and particle discriminator. The system may have a sheath air stage including a port for providing sample air, at least one sheath air inlet port for providing sheath air, and a sheath air combining region. The system may include an airflow compression stage having a varying air channel that narrows as the air stream traverses the airflow compression stage to pre-concentrate particles within an interior region of the air stream. The system may include an airflow expansion stage having an air channel that widens to slow the airstream and particle velocities. A portion of the air channel height may be narrowed to allow larger thermophoretic forces to be generated.

Abstract: In a measuring method for measuring an atmospheric concentration of a compound, such as a volatile organic compound (VOC), an adsorptive element is provided within a target atmosphere for a period of time to allow adsorption of a compound of interest for mea adsorptive element is measured, and then removed from the target atmosphere, and placed within a closed measuring space. The adsorptive element is heated within the measuring space to cause de-adsorption of the compound into the closed measuring space, and a concentration of the de- adsorbed compound is measured. A concentration of the compound in the target atmosphere is determined based on the concentration of the compound within the closed measuring space. The adsorptive element may be formed of an adsorptive material such as carbon fibers, cellulose or other adsorptive materials, and a binder. The adsorptive element may be optimized for adsorption of a specific compound.

Abstract: The following is an apparatus and a method that enables the automated collection and identification of airborne particulate matter comprising dust, pollen grains, mold spores, bacterial cells, and soot from a gaseous medium comprising the ambient air. Once ambient air is inducted into the apparatus, aerosol particulates are acquired and imaged under a novel lighting environment that is used to highlight diagnostic features of the acquired airborne particulate matter. Identity determinations of acquired airborne particulate matter are made based on captured images. Abundance quantifications can be made using identity classifications. Raw and summary information are communicated across a data network for review or further analysis by a user. Other than routine maintenance or subsequent analyses, the basic operations of the apparatus may use, but do not require the active participation of a human operator.

Abstract: Techniques are disclosed for using synthetic jet technology as an air delivery device for sensing applications. In particular, a synthetic jet device is used to deliver a controlled airflow or other fluidic flow to a sensor measurement area. Such a sensing system can be used to detect accurate concentration of target features present in the ambient surroundings, such as gases, particles, solutions, mixtures, and any other environmental features that can be sensed from a controlled airflow. An example application is air quality monitoring by using one or more synthetic jet devices to deliver a known or otherwise controlled airflow to a sensing area, thereby allowing for detection of harmful or otherwise unacceptable concentrations of particulate matter, gases, or air pollutants. In some embodiments, a synthetic jet device is operatively coupled with a sensor via a flow channel in a common housing, so as to provide a controlled flow sensing system.
