The present invention is related to the field of bio/chemical sensing, assays and applications. Particularly, the present invention is related to collecting a small amount of a vapor condensate sample (e.g. the exhaled breath condensate (EBC) from a subject of a volume as small as 10 fL (femto-Liter) in a single drop), preventing or significantly reducing an evaporation of the collected vapor condensate sample, analyzing the sample, analyzing the sample by mobile-phone, and performing such collection and analysis by a person without any professionals.

A temperature and humidity sensing device including a body and a temperature and humidity sensor is provided. The body has an inlet hole, an outlet hole, and a flow channel. The inlet hole and the outlet hole are opposite to each other, and the flow channel is configured to communicate the inlet hole and the outlet hole. The temperature and humidity sensor is disposed in the flow channel. The temperature and humidity sensor is configured to sense the relative humidity of air in the surrounding environment of the body during the air in the surrounding environment of the body flows into the flow channel from the inlet hole and flows through the flow channel to flow out from the outlet hole.

An actuating and sensing module includes a first substrate, a second substrate, an actuating device and a sensor. The first and second substrates are stacked on each other as a gas flow channel is formed therebetween. The gas inlet, the gas flow channel and the gas outlet are in communication with each other to define a gas flow path. The actuating device is disposed in the gas outlet of the second substrate and electrically connected to a control circuit to obtain driving power. The sensor is disposed in the gas flow path and misaligned with the gas inlet. The sensor is spaced apart from the actuating device and is electrically connected to the control circuit. Being driven by the actuating device, the gas is transported from the outside into the gas flow path and monitored by the sensor.

A gas detecting module includes a carrying plate, a sensor, a compartment body and an actuator. The carrying plate has a substrate and a gas opening. The compartment body is divided into a first compartment and a second compartment by a partition plate. The first compartment has an opening. The second compartment has an outlet and accommodates the actuator. The bottom of the compartment body has an accommodation recess receiving the carrying plate, whereby the gas opening is aligned with the outlet, and the sensor packaged on the substrate is disposed within the first compartment through the opening. The partition plate has a notch. The gas detecting module is assembled in a slim-type portable device having a casing. The casing has an inlet aligned with the first compartment. As the actuator is actuated, ambient gas is inhaled into the first compartment, and the sensor detects the gas flowing therethrough.

An airborne particle collection system includes a monitoring device and a collection media. The monitoring device includes a housing having an air-intake slot, and a motor. The collection media includes an adhesive-coated tape contained within a removable cartridge inserted into the housing. The removable cartridge includes a particle intake zone, proximate to the air-intake slot, and through which the adhesive-coated tape is exposed to capture airborne particles passing through the air-intake slot, and an inspection zone at which the airborne particles captured at the intake zone are transported for optical imaging. The motor moves the airborne particles captured by the adhesive-coated tape from the particle intake zone to the inspection zone.

The invention relates to a diffusive gradient in thin-films device comprising a casing (2) comprising a first portion and a second portion defining therebetween a housing (3) for accommodating at least one component-diffusing layer (4), said component coming from an environment exterior to the device. According to the invention, the casing includes at least two orifices (6, 7) ensuring the exposure of the diffusion layer to the exterior of the device. The invention also relates to an apparatus for developing a diffusive gradient in thin-films device comprising such a device.

A collecting apparatus comprises: a housing which is long and includes a housing space capable of housing a collecting member, the housing having formed therein an inflow port and an outflow port; a gas flow generator that generates a gas flow within the housing space; and a holding portion that holds the collecting member in a position that the gas flow flows, the inflow port being formed on a more upstream side than the collecting member held by the holding portion, and the outflow port being formed on a more downstream side than the collecting member held by the holding portion, and the outflow port opening toward the downstream side such that air that has flowed out from the outflow port flows along a housing outer surface on a more downstream side than the outflow port.

Embodiments relate to systems and methods for dissipating heat within a gas detector. A gas detector may comprise an airflow generator configured to generate a sample gas flow through the gas detector; a sample gas flow line configured to direct the sample gas flow within a housing of the gas detector from an inlet of the gas detector toward an outlet of the gas detector; a sensor, in fluid communication with the airflow generator via the sample gas flow line, configured to detect one or more potentially hazardous gases within the sample gas flow; and a heat sink, in fluid communication with the airflow generator and positioned after the sensor along the sample gas flow line, configured to transfer heat from an interior of the housing to the sample gas flow, wherein the sample gas flow is directed out of the housing via the outlet of the gas detector.

An improved device for collecting particulate matter suspended in the ambient air is disclosed comprising a container extending between an open first end and a closed second end defining a container interior. A container output communicates with a container interior located proximate the closed second end of the container. A filter cassette comprising a collection filter is permanently affixed to a filter holder. A retainer having a retainer input retains the filter cassette between the retainer input and the container output. An output connector connects the container output to a low pressure source for drawing ambient air into the retainer input for enabling the collection filter to collect particulate matter suspended in the ambient air entering the retainer input. Preferably, the filter holder and the filter are disposable.

A plug-in air quality detector, a control method, and a control circuit are provided in the field of air quality detection. The plug-in air quality detector comprises a casing, a sensor component, a control circuit and a connector component. The connector component includes a power supply terminal and a data terminal, and is configured to connect the plug-in air quality detector with a user device. As such, the detector may prompt a user of the air quality around the user without being configured with a dedicated power supply and a dedicated display screen, thereby achieving the effects of reducing the size and the weight of the air quality detector and improving the ease of use.
