A collector device of environmental exposure is provided. This device may be used to collect and, after technical upgrade, monitor environmental exposure in personal and stationary settings. By coupling with advanced genomic analysis and chemical analysis technologies, the device and its accompanying methodology are capable of detecting environmental agents of diverse nature, many of which could pose health risks if going unaware of or uncontrolled. This type of information provides much needed clues to reconstruct and pinpoint the course of disease etiology at both personal and epidemic scales. By combining personal exposome and personal omics analyses, we can recapitulate with the intention to then prescribe treatment plans with unprecedented precision.

A blower is configured to draw air past the sampling device, through the opening, and through the plenum, such that a measuring portion of the air flows through the flow connection and through the mass flow meter, which measured the flow rate of the measuring portion.

An air sampling system is disclosed. The air sampling system includes: an air inflow channel having an air inlet portion at a top end, the air inflow channel being oriented substantially vertically; a fan configured to cause air in a sampling environment to flow into the air inflow channel via the inlet portion; a cooling unit for cooling air in the air inflow channel, the cooling unit disposed downstream of the inlet portion; a collection chamber for collecting liquid water condensed from air in the air inflow channel, the collection chamber being fluidly connected to the air inflow channel; and a sensing unit for determining a volume of liquid in the collection chamber, wherein the cooling unit is controlled in response to signals generated by the sensing unit.

Various embodiments include heat and volatile-organic-compounds detecting systems. In one example, the heat-detecting system includes at least one heat sensor mounted externally to a device, such as a local power-box (LPB). The heat sensor has an area-of-detection to detect heat emitted from at least one face of the LPB at one or more locations. The heat-detecting system also includes a high-absorptance infrared-collector (HAIC) formed within the LPB to collect excessive heat generated by a component within the LPB. The excessive heat is correlated to a pre-determined temperature level, and a temperature of the collected excessive heat is measured by the heat sensor. Each of the heat sensor and the HAIC are coupled to a control module. Other apparatuses, designs, and methods are disclosed.

A flow means with a housing and a fan to generate a fluid flow within a pipe or hose line of an intake monitoring system. The fan can be connected to the pipe or hose line via connecting pieces and can be driven to rotateaxis . The invention creates a flow means (100) which enables the direction of flow to be reversed. Respective blocking means are assigned to the connecting pieces and can be moved from an intake position (PS), in which an intake region of the fan is connected to the respective connecting piece into an exhaust position (PB), in which an exhaust region of the fan is connected to the respective connecting piece so the flow within the pipe or hose line is in a first direction of flow (S1) or in a second direction of flow (S2) as a function of the position (PS, PB) of the blocking means.
