Systems and methods monitor a space for environmental pollutants. A sensing device senses and reports air quality anomalies to a cloud detection service. The cloud detection service uses artificial intelligence to analyze raw sensor data from the sensing device, determines whether the raw sensor data indicates an air quality event, and sends an air quality report indicative of the air quality event to a client device associated with the sensing device and/or the monitored space. A sensing device may be deployed in an air extraction vent to detect and report indications of vaping in prohibited spaces. A sensing device may be deployed in a vehicle to detect and report smoking in vehicles where smoking is prohibited. An application running on a mobile device reports detection of a short-range wireless beacon within a serviceable space to a cloud detection service, which tracks servicing of the serviceable space.

A gas detection device and process detect a combustible target gas. A detector chamber (6) encloses a detector (10), and a modulator chamber (5) encloses a modulator (15). The target gas can flow from an area to be monitored through into the modulator chamber and from the modulator chamber into the detector chamber. An electrical voltage is applied to the modulator and to the detector to heat them, oxidizing the target gas in the modulator chamber and in the detector chamber. Heat energy is released bringing about an increase of the temperature of the detector. A detector sensor measures a detection variable which depends on the detector temperature. The voltage is applied to the modulator such that the temperature of the modulator oscillates. An analysis unit checks whether the detection variable oscillates synchronously with the modulator temperature, indicating the target gas is present.

A display assembly system which detects abnormal operating conditions, such as gas recirculation or airway occlusion, is provided. An electronic display is located within a housing. Sensors measure characteristics of ambient air ingested by a thermal management subsystem. Weather conditions are gathered for a location, and measurements are received from the sensors regarding characteristics of the ingested ambient air. An alert is generated if the measurements change at a rate different from a rate of change of the weather conditions by at least a preterminal amount.

According to the method, either CO2-free air or pure nitrogen N2 is pumped into the cooling circuit selectively depending on system parameters. To this end, the method ensures that the air injection rate is high enough that, under normal conditions, the hydrogen concentration in the tank and in the riser remains below 2% H2. On air injection, the oxygen O2 (>2 ppm) in the cooling water reacts with the copper in the cooling ducts and a layer of copper oxide forms on the inner walls of said ducts. No reaction is triggered by the injection of nitrogen N2. The CO2 content in the injection air and, at the same time, also the H2 content in the exhaust air are continuously measured and monitored, and an alarm is triggered if adjustable limit values are exceeded. The equipment for performing the method comprises an electronic control unit (65) with an input field and display as a control box, and a pump and a pipe circuit for drawing air in from the riser. The control unit (65) can evaluate all the measured data from the sensors and analysers connected to the pipe and can at least check the CO2 content in the supply air and the H2 content in the riser (13) and display the hydrogen leakage.

A vehicle control system includes: a first vehicle including a smell detection unit, a smell determination unit configured to determine whether an intensity of the smell is equal to or larger than a predetermined threshold value, a first acquisition unit configured to acquire first vehicle position information indicating a position of the first vehicle, and a notification unit configured to notify a second vehicle about the first vehicle position information when the smell determination unit determines that the intensity of the smell is equal to or larger than the predetermined threshold value; and a second vehicle configured to communicate with the first vehicle and including an information output processing unit configured to cause an information output unit to output a warning notifying about a presence of the first vehicle when an approach determination unit determines that first vehicle is positioned less than the predetermined distance from the second vehicle.

The present disclosure relates to providing a continuous, autonomous monitoring system of environmental parameters, harmful gases and greenhouse gases in animal stables. A network of internet-of-things (IoT) sensors can be installed in a stable that produce alarm signals in case of danger or if predetermined threshold values are exceeded. The sensors work continuously and communicate through different wireless protocols with a dedicated cloud platform. The cloud platform stores the values received by the various sensor units and transmitted via dedicated monitoring devices and elaborates them applying data analysis processes.

A display assembly which detects abnormal operating conditions, such as gas recirculation or airway occlusion, is provided. An electronic display is located within a housing. An airflow pathway travels through the housing and is configured to accept, circulate, and exhaust air by way of one or more fans. One or more sensors measure characteristics of the air. Weather conditions for a location of the display assembly are gathered, measurements from the sensors are received, and a determination is made as to whether the measurements of the ingested air are within a margin of error expected measurements derived from the gathered weather conditions. An alert is generated if the measurements of the ingested air are not within the margin of error.

A portable chemical contaminant detection system and related method is provided. The detection system includes a detector having one or more probes and associated detector circuitry that is in communication with a mobile device. The system is in communication with a remotely located server, where the detection system transmits contaminant detection signals while measuring a fluid from a product or a container of a chemical used on the product. The contaminant detection signals are transmitted in real-time and the detection system receives contaminant level information determined by the server. The server may process data from multiple probes to track multiple contaminants or a single contaminant based on the multiple different probe data from a single detector. The system displays real-time decontamination feedback and displays process completion notification or automatically implements decontamination shut-off. The server tracks location information and contaminant levels for products and communicates with third party certification servers.
