摘要： This invention consists of sensors and algorithms to image, detect, and quantify the presence of hydrocarbon gas (for example from leaks) using a short-wave infrared radiation detector array with multiple spectral filters under natural sunlight or artificial illumination, in combination with the hydrodynamics of turbulent gas jets and buoyant plumes. Multiple embodiments are recited and address detection and quantification of methane gas leaks. Quantification includes gas column densities, gas concentration estimates, total mass, hole size estimates, and estimated emission flux (leak rate) of gas from holes and cracks in pressurized vessels, pipes, components, and general gas infrastructure, and from surface patches (for example due to gas leaks in underground pipes) under the action of buoyancy and wind. These and similar embodiments are applicable more generally to natural gas and other hydrocarbon gases, liquids, emulsions, solids, and particulates, and to emissions monitoring of greenhouse gases methane and carbon dioxide.

摘要： A system (20) and method (100) using decentralized trace gas sensors (44a, 44b, 44c) and a central control element (46) to detect smoldering material in particulate material processing equipment (26) with continuous air flow (22, 24, 34). First and second sensors (44a, 44c) measure gas concentrations at an air inlet (22) and an air outlet (34), respectively. The control element (46) receives the measurements from the sensors (44a, 44c) simultaneously, considers the first and second concentrations simultaneously to determine an amount of gas being produced in the processing equipment (26), determines whether the amount of gas being produced exceeds a threshold value indicative of smoldering, and if so, activates an alarm. A user interface (48) allows a user to interact with the control element (46), including resetting the alarm, viewing current and stored sensor and system information, and initiating a test of the system by exposing the sensors (44a, 44b, 44c) to gas released from a gas reservoir (50a, 50b, 50c).

摘要： Embodiments of the invention can sample particulates, aerosols, vapors, and/or biological components of ambient air utilizing spherical air-sampling filters. Components of the embodiments may include a storage magazine for holding a plurality of spherical air-sampling filters, an air-sampling manifold configured to deliver an air-sampling filter from the storage magazine to a sampling location, and an air compressor to perform an air sampling operation and to transport a used air-sampling filter away from the sampling location. Operation of some embodiments may begin by rotating a slotted drum within the air-sampling manifold to deliver an air-sampling filter from the storage magazine to the sampling position. Operation may continue by using the air compressor to draw air from an ambient environment through the air-sampling filter. After sampling is complete, the air compressor may be utilized to pneumatically transport the used air-sampling filter away from the sampling position to a filter retrieval location via a transport tube. These operations can be pre-programmed locally or triggered by remote communication. Operation may continue uninterrupted due to a plurality of unused air-sampling filters retained in the storage manifold. Because operations can be triggered remotely and air samples are autonomously transported off site, embodiments of this invention eliminate unnecessary risks to human health created by other air-sampling devices, which require an operator to be present at a potentially hazardous sampling site to activate the device or retrieve air samples. Embodiments of the invention can be installed pre-emptively to eliminate risks to human health created when an operator must deliver a portable air-sampling device to a potentially contaminated sampling site. Furthermore, embodiments of the invention allow rapid retrieval of air samples following sample collection, which can expedite analysis and identification of aerosols and consequently help minimize human exposure to potentially dangerous and life-threatening chemical and biological contaminants.

摘要： Provided is a technique of analyzing particles in real time while collecting and condensing the particles continuously. Gas and/or particles as a detection target substance that are attached to an authentication target 2 are removed by air flow from a blowing region 5. The removed sample is sucked and is condensed and sampled at a sampling region 10, and ions of the sample are generated at an ion source 21 and are then subjected to mass analysis at a mass analysis region 23. Determination of the obtained mass spectrum is made as to the presence or not of a mass spectrum derived from the detection target substance, and a monitor 27 displays a result thereof. Thereby, the detection target substance attached to the authentication target 2 can be detected continuously in real time, promptly and with a less error rate.

摘要： An air purifier is presented with a sensor controlling a motorized fan, wherein the sensor continuously and automatically adjusts the sensitivity setting of the sensor as the quality of air being purified changes. The average air quality readings of the air passing through an air purifier are monitored over a designated time period and, as the quality fluctuates, the sensitivity of the sensor is automatically adjusted. If the air quality is poor (i.e. a high particulate count), the sensitivity of the sensor will be adjusted to a less sensitive setting (i.e. allowing higher fan speeds so that more air can be moved through the filter) and, if the air quality is good (i.e. a low particulate count), the sensitivity of the sensor will be adjusted to a more sensitive setting (i.e. setting a lower maximum fan speed because not as much air needs to move through the filter).
