Handheld, single reading monitor - giving point readings from individual gas collection wells. There are two companies that provide the large majority of these type of meters, LANDTEC and Elkins Earthworks. Wired, continuous reading monitor - these hard wired monitors can typically be found at either the flare or the landfill gas-to-energy plant.
An encoder that inserts the tones subliminally into a station's or broadcast network's airchain via psychoacoustic masking. A monitor that checks that the encoder is working properly. The wearable Portable People Meter carried by each panelist. A base station for each PPM, where each panelist in the household places it overnight to recharge the ...
Greenhouse gas monitoring is the direct measurement of greenhouse gas emissions and levels. There are several different methods of measuring carbon dioxide concentrations in the atmosphere, including infrared analyzing and manometry. Methane and nitrous oxide are measured by other instruments.
The most common principles for CO 2 sensors are infrared gas sensors and chemical gas sensors. Measuring carbon dioxide is important in monitoring indoor air quality , [ 1 ] the function of the lungs in the form of a capnograph device, and many industrial processes.
An electronic circuit containing a feedback loop controls the gas-pump current to keep the output of the electrochemical cell constant, so that the pump current directly indicates the oxygen content of the exhaust gas. This sensor eliminates the lean–rich cycling inherent in narrow-band sensors, allowing the control unit to adjust the fuel ...
Products, services, and subsidiaries have been offered from International Business Machines (IBM) Corporation and its predecessor corporations since the 1890s. [1] This list comprises those offerings and is eclectic; it includes, for example, the AN/FSQ-7, which was not a product in the sense of offered for sale, but was a product in the sense of manufactured—produced by the labor of IBM.
High-g training is done by aviators and astronauts who are subject to high levels of acceleration ('g'). It is designed to prevent a g-induced loss of consciousness (g-LOC), a situation when the action of g -forces moves the blood away from the brain to the extent that consciousness is lost.
The air station is the former location of Pacific Fleet fighter and Airborne Early Warning and Control aircraft (F-4 Phantom II, F-14 Tomcat, E-2 Hawkeye) and is best known as the former location of the United States Navy Fighter Weapons School (NFWS), its TOPGUN training program and the movie of the same name.
