Abstract: In certain embodiments, a portable atmospheric monitor comprises a housing at least partially enclosing an inner chamber. The housing comprises an inlet and an aperture. The monitor also includes at least one light sensor arranged within the housing. The light sensor that senses one or more wavelengths of sunlight received via the aperture. The monitor includes at least one light-scattering sensor that senses PM received via the inlet. The monitor includes a processor arranged within the housing and coupled to the at least one light sensor and the at least one light-scattering sensor. The processor is configured to: receive a light signal from the at least one light sensor; receive a PM signal from the at least one light-scattering sensor; determine the aerosol optical depth based upon the light signal; and determine the PM concentration based upon the PM signal.

Abstract: A portable sampling device includes a housing at least partially enclosing an inner chamber and an airflow assembly disposed within the inner chamber and comprising a portion of an airflow path. The airflow assembly includes a portion of a printed circuit board (PCB); a manifold configured to be sealably coupled to the portion of the PCB to define at least one airflow channel disposed between an inner surface of the manifold and an outer surface of the PCB; and one or more pumping elements positioned on the PCB.

Abstract: A portable sampler, the sampler including a sampler assembly having a housing that includes a receiver defined therein for interchangeably receiving a number of removable inlet assemblies, the removable inlet assemblies including a respirable inlet assembly and a thoracic inlet assembly. The respirable inlet assembly includes a hybrid cyclone assembly, the hybrid cyclone assembly including an impaction stage and a cyclone in series. The thoracic inlet assembly includes an inlet slot configured to function as a size-selective inlet. Another thoracic inlet assembly includes a housing having a number of openings configured to receive a sample airflow; an inlet insert through which an inlet aperture is defined; a prequalification chamber defined between a lower surface of the housing and an upper surface of the inlet insert; and a protrusion extending downward from the lower surface of the housing into the inlet aperture of the inlet insert to from an inlet slot.

Abstract: A combustion chamber, having an upper part and a lower part, may include an annular constriction, in combination with the combustion chamber, to aid in directing partially combusted gases such as carbon monoxide away from the periphery of the combustion chamber back toward its center, and into the flame front. The annular constriction may also impede the flow of partially combusted gases located at the periphery, thus increasing the time these gases spend within the combustion chamber and increasing the likelihood that any products of incomplete combustion will undergo combustion. The combustion chamber may further comprise a dual burner cooktop for directing combustion gases and exhaust to multiple cooking vessels. In further embodiments, the combustion chamber may be made of, lined, or clad with a metal alloy comprising iron, chromium, and aluminum.
Abstract translation: 具有上部和下部的燃烧室可以包括与燃烧室组合的环形收缩部,以帮助将部分燃烧的气体例如一氧化碳从燃烧室的周边引导回其中心, 并进入火焰前沿。 环形收缩也可能阻碍位于周边的部分燃烧气体的流动,从而增加这些气体在燃烧室内消耗的时间,并增加任何不完全燃烧产物将经历燃烧的可能性。 燃烧室还可以包括用于将燃烧气体和排气引导到多个烹饪容器的双燃烧器炉灶。 在另外的实施例中,燃烧室可以由包含铁,铬和铝的金属合金制成,内衬或包覆。

Abstract: A sampling device is constructed having an airflow path from a size-selective inlet to a device outlet, without using any tubing. The size-selective inlet includes at least one of an impactor, a filter, a cyclone, and an inhalable inlet. The device includes a sampling assembly configured to be removably coupled directly to a sampling device housing (e.g., without using tubing), and an airflow assembly that may be constructed without using tubing.
