Infrared thermometer. An infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called black-body radiation emitted by the object being measured. They are sometimes called laser thermometers as a laser is used to help aim the thermometer, or non-contact thermometers or temperature guns ...
The clathrate gun hypothesis is a proposed explanation for the periods of rapid warming during the Quaternary. The hypothesis is that changes in fluxes in upper intermediate waters in the ocean caused temperature fluctuations that alternately accumulated and occasionally released methane clathrate on upper continental slopes.
Normal human body temperature ( normothermia, euthermia) is the typical temperature range found in humans. The normal human body temperature range is typically stated as 36.5–37.5 °C (97.7–99.5 °F). [ 8][ 9] Human body temperature varies. It depends on sex, age, time of day, exertion level, health status (such as illness and menstruation ...
Directed-energy weapon. Police car equipped with an LRAD -500X sonic weapon (Warsaw, Poland, 2011). A directed-energy weapon ( DEW) is a ranged weapon that damages its target with highly focused energy without a solid projectile, including lasers, microwaves, particle beams, and sound beams.
Human thermoregulation. As in other mammals, human thermoregulation is an important aspect of homeostasis. In thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. [ 1] Humans have been able to adapt to a great diversity of climates, including hot ...
The Active Denial System ( ADS) is a non-lethal directed-energy weapon developed by the U.S. military, [ 2] designed for area denial, perimeter security and crowd control. [ 3] Informally, the weapon is also called the heat ray[ 4] since it works by heating the surface of targets, such as the skin of targeted human beings.
Thermal comfort is the condition of mind that expresses subjective satisfaction with the thermal environment. [ 1] The human body can be viewed as a heat engine where food is the input energy. The human body will release excess heat into the environment, so the body can continue to operate. The heat transfer is proportional to temperature ...
Thermography. Thermogram of a traditional building in the background and a "passive house" in the foreground. Infrared thermography ( IRT ), thermal video and/or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of ...
