The U.S. Army Prime Power School is run by the United States Army Corps of Engineers at Fort Leonard Wood, Missouri since January 2011, having previously moved from Fort Belvoir, Virginia. The mission of the school is to produce MOS 12P – Prime Power Production Specialists (formerly MOS 52E and 21P) for the U.S. Army .
According to the team that created the device, the vibrations from the heart muscles would be enough to allow the generator to power a pacemaker. [2] This would eliminate the need to replace the batteries surgically. In 2012 a group at Northwestern University developed a vibration-powered generator out of polymer in the form of a spring.
Small variable-frequency drive Chassis of above VFD (cover removed). A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the ...
All of the generating plants at the Morgantown Generating Station were built by the Potomac Electric Power Company, which sold them to the Southern Company in December 2000 as a result of the restructuring of the electricity generating industry in Maryland.
An improvised explosive device in Iraq. When activated, the concave copper shape on top becomes an explosively formed penetrator.. EFPs have been used in improvised explosive devices against armoured cars, for example [10] in the 1989 assassination of German banker Alfred Herrhausen (attributed to the Red Army Faction) [11] and by Hezbollah in the 1990s.

A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...
They installed the new pickups on all their electric models, starting in July 1940, renaming the ES-100 and 250 to ES-125 and 300). On the ES-150, Gibson moved the pickup (with adjustable individual poles) closer to the bridge for a more "biting" sound for soloing.
In 1962 the adjustable bridge was introduced. In 1967 the tuner knobs were changed to metal. In 1970, the model was discontinued as a result of the acquisition of the Gibson company by Norlin, but in 1972, the Japanese-made FT-145 (Natural) and FT-145SB (Sunburst) was introduced and ended in 1980.
