    摘要： A gas detecting device includes a casing, at least one gas transporting actuator, at least one valve and at least one external sensor. The casing has an airflow chamber, an inlet, a branch channel and a connection channel. The airflow chamber communicates with an environment outside the casing through the inlet, and the branch channel communicates with the airflow chamber and the connection channel. The gas transporting actuator is disposed on the branch channel for transporting air into the airflow chamber and the branch channel from the inlet and has a gas inlet plate, a resonance plate and a piezoelectric actuator. The valve is disposed between the connection channel and the branch channel for controlling the air to flow into the connection channel. The external sensor is detachably disposed in the connection channel and has a sensor for measuring the air in the connection channel.

    摘要： A spectral imaging system configured to obtain spectral measurements in a plurality of spectral regions is described herein. The spectral imaging system comprises at least one optical detecting unit having a spectral response corresponding to a plurality of absorption peaks of a target chemical species. In an embodiment, the optical detecting unit may comprise an optical detector array, and one or more optical filters configured to selectively pass light in a spectral range, wherein a convolution of the responsivity of the optical detector array and the transmission spectrum of the one or more optical filters has a first peak in mid-wave infrared spectral region between 3-4 microns corresponding to a first absorption peak of methane and a second peak in a long-wave infrared spectral region between 6-8 microns corresponding to a second absorption peak of methane.

    摘要： The present disclosure is directed to a gas sensor that includes an active sensor area that is exposed to an environment for detection of elements. The gas sensor may be an air quality sensor that can be fixed in position or carried by a user. The gas sensor includes a heater formed above chamber. The gas sensor includes an active sensor layer above the heater that forms the active sensor area. The gas sensor can include a passive conductive layer, such as a hotplate that further conducts and distributes heat from the heater to the active sensor area. The heater can include a plurality of extensions. The heater can also include a first conductive layer and a second conductive layer on the first conductive layer where the second conductive layer includes a plurality of openings to increase an amount of heat and to more evenly distribute heat from the heater to the active sensor area.
