  2. Heat detector - Wikipedia

    en.wikipedia.org/wiki/Heat_detector

    A heat detector is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The thermal mass and conductivity of the element regulate the rate flow of heat into the element. All heat detectors have this thermal lag. Heat detectors have two main classifications of ...

  3. Electrical equipment in hazardous areas - Wikipedia

    en.wikipedia.org/wiki/Electrical_equipment_in...

    In electrical and safety engineering, hazardous locations (HazLoc, pronounced haz·lōk) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations can provide an ignition source, due to ...

  4. Intrinsic safety - Wikipedia

    en.wikipedia.org/wiki/Intrinsic_safety

    Intrinsic safety (IS) is a protection technique for safe operation of electrical equipment in hazardous areas by limiting the energy, electrical and thermal, available for ignition. In signal and control circuits that can operate with low currents and voltages, the intrinsic safety approach simplifies circuits and reduces installation cost over ...

    en.wikipedia.org/wiki/Safety_lamp

    Safety lamp. A safety lamp is any of several types of lamp that provides illumination in places such as coal mines where the air may carry coal dust or a build-up of inflammable gases, which may explode if ignited, possibly by an electric spark. Until the development of effective electric lamps in the early 1900s, miners used flame lamps to ...

    The IR radiation passes through the dome and then through lenses that focus the energy. The IR energy is reflected by mirrors on to the FPA. The seeker is a two-dimensional staring FPA of 64×64 MerCad (HgCdTe) detector elements. [32] The FPA processes the signals from the detectors and relays a signal to the missile's tracker.

  7. IceCube Neutrino Observatory - Wikipedia

    en.wikipedia.org/wiki/IceCube_Neutrino_Observatory

    The IceCube Neutrino Observatory is composed of several sub-detectors which is also in addition to the main in-ice array. AMANDA, the Antarctic Muon And Neutrino Detector Array, was the first part built, and it served as a proof-of-concept for IceCube. AMANDA was turned off in May 2009. [12]

  8. Detonation - Wikipedia

    en.wikipedia.org/wiki/Detonation

    Detonation (from Latin detonare 'to thunder down/forth') [1] is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations propagate supersonically through shock waves with speeds about 1 km/sec and differ from deflagrations ...

  9. Nuclear weapon design - Wikipedia

    en.wikipedia.org/wiki/Nuclear_weapon_design

    The use of plutonium affects weapon design due to its high rate of alpha emission. This results in Pu metal spontaneously producing significant heat; a 5 kilogram mass produces 9.68 watts of thermal power. Such a piece would feel warm to the touch, which is no problem if that heat is dissipated promptly and not allowed to build up the temperature.
