摘要： The present disclosure provides a gas sensor comprising a gas sensing layer fabricated based on a solution-processed, template-free synthesis method that achieves controllable ZnO nanostructured morphologies. The method is based on promotion and suppression of growth at specific crystallographic dimensions by tuning the polarity of the solvent. The gas sensing layer with the ZnO nanostructures exhibits high response, excellent selectivity and rapid recovery time.

摘要： Certain aspects of the present disclosure provide methods and apparatus for closed-loop control of a system using one or more electron paramagnetic resonance (EPR) sensors located on-site. With such EPR sensors, a change can be applied to the system, the EPR sensors can measure the effect(s) of the change, and then adjustments can be made in real-time. This feedback process may be repeated continuously to control the system.

摘要： Embodiments of the present disclosure enable rapid detection of viruses present in ambient air flows. A fan disposed in an ambient environment may be activated to direct an air flow to an ambient inlet of an analysis device. As an ambient air flow enters an inlet of the analysis device, a heating element may introduce heat into the air flow, causing VOCs to be released. A mass spectrometer-based analysis device may be used to analyze the VOCs to detect the presence of one or more target VOCs that indicate the presence of a virus or other harmful molecule in the ambient air flow.

摘要： Intrinsically safe and explosion proof enclosure platforms for convertible gas detectors are disclosed. In some embodiments, a convertible gas detector comprises a gas sensor, the gas sensor comprising sensor circuit. The gas detector further comprises an enclosure, the enclosure configured to house the sensor circuit. The gas sensor further comprises an end cap, the end cap configured to be detachably connected to the enclosure along a flamepath joint. The gas detector is configured to switch between operating as an explosion proof detector and an intrinsically safe detector responsive to whether the end cap is connected to the enclosure.

摘要： A chemical release detection system includes a camera, an output control member, a mitigation member, and a controller in operative communication with the camera, the output control member, and the mitigation member. The camera is configured to detect a chemical release. The output control member is configured to generate commands. The mitigation member is configured to reduce risk generated by the chemical release based on the commands by the output control member. The controller is configured to notify a user of the chemical release, and provide an origin of the release and a direction of the release. The controller controls the operation of the output control member and the mitigation member.

摘要： A small-sized, portable enclosure protects a gas sensor against degradation due to environmental exposure and changes in atmospheric conditions. The protective enclosure includes an inlet for introduction of a gas into the enclosure, an outlet for release of the gas upon completion of a sensing run, and a number of in-line filters that remove from the inflowing gas sample analytes, contaminants, and other materials that can compromise the integrity of the sensor or cause the sensor to degrade over time. The enclosure does not include any filters during the measurement phase of the sensing run in order to allow the gas sensor to accurately measure an unmodified gas mixture and/or analyte.

摘要： A system for redundantly detecting a gas is provided. The system includes first and second series-connected gas sensors and a signaling module. If both gas sensors are functioning normally, the signaling module provides an alert when both gas sensors detect a predetermined gas concentration. If however any one of the gas sensors is experiencing a fault condition, the faulty gas sensor's alarm is shunted by operation of a fault relay, and the signaling module provides an alert when the non-faulty gas sensor detects a predetermined gas concentration. If both gas sensors are experiencing a fault condition, both gas sensors' alarms are shunted by fault relays, and an audible and/or visual alert is generated by the signaling module. Embodiments of the present invention are well suited for industrial facilities, manufacturing facilities, research and development laboratories, and other locations where unsafe gas concentrations may become present.

摘要： In a noise removing apparatus, a data acquisition unit acquires sets of odor data measured using a sensor with respect to a plurality of objects, each set of odor data representing features of an odor of an object by respective rates of a plurality of odor molecules. A noise component extraction unit extract a noise component using a set of odor data. A noise removing unit removes the noise component from each set of odor data to be processed.
