Variable Speed Fire Pump Controllers were invented and released with a UL Listing for fire pump service in 2003 by Master Control Systems, Inc. [1] [2] Paragraph 10.5.5 in the 2003 edition of NFPA-20 recognized Variable Speed as an accepted method for operating the fire pump. Then in the NFPA-20 2007 edition, section 10.10 was added to clarify ...
Plasma oscillations, also known as Langmuir waves (after Irving Langmuir), are rapid oscillations of the electron density in conducting media such as plasmas or metals in the ultraviolet region. The oscillations can be described as an instability in the dielectric function of a free electron gas. The frequency depends only weakly on the ...
During testing the Kerrison Predictor provided accurate fire control to a range in excess of 1,500 m (4,900 ft), and the Bofors gun was reliable. In the fall of 1940, the Ordnance Department standardized the Kerrison Predictor for use with their 37 mm gun. By February 1941, the U.S. Navy had adopted the Bofors for use on their ships.
Like many other pieces of Coast Artillery fire control equipment, the deflection board was a mechanical analog computer that used methods of similar triangles to solve the problems of correcting fire for wind speed and direction, drift of the projectile, and angular travel of the target during the observing interval.

The AN/APG-78 Longbow is a millimeter-wave fire-control radar (FCR) target acquisition system and the Radar Frequency Interferometer (RFI), which are housed in a dome located above the main rotor. [4] [5] The radome's raised position enables target detection while the helicopter is behind obstacles (e.g. terrain, trees or buildings). The APG-78 ...

SMASH Handheld in hebrew: פגיון (Pigyon), is a high-tech fire-control system developed by the Israel-based company SMARTSHOOTER.The device is an external add-on solution that can be installed to most existing firearms. [1]
Rear view of the AN/SPG-55B aboard USS Worden (CG-18).. The AN/SPG-55 was an American tracking / illumination radar for Terrier and RIM-67 Standard missiles (SM-1ER/SM-2ER). ). It was used for target tracking and surface-to-air missile guidance as part of the Mk 76 missile fire control system
