The generic FLASH technique emerges as a gradient echo sequence which combines a low-flip angle radio-frequency excitation of the NMR signal (recorded as a spatially encoded gradient echo) with a rapid repetition of the basic sequence. The repetition time is usually much shorter than the typical T1 relaxation time of the protons in biologic ...
Sub-MeV radiation from a nuclear explosion may be more important in (empty) space. Given this realization, during the 1960s [3] the U.S. military began to investigate whether military systems could be tested for their response to nuclear-weapon generated pulsed x-rays with flash x-ray machines. At the time these were fairly small, primarily ...
This game was known for having the first background sound for a pinball game, as well as the first pinball game to use flash lamps. [2] Steve Ritchie designed about 90% the game on a cocktail napkin during a flight, while flying from Atari to Williams. The game also broke the factory production record at Williams and is still Ritchie's biggest ...
A dyno torch, dynamo torch, or squeeze flashlight is a flashlight or pocket torch which generates energy via a flywheel.The user repeatedly squeezes a handle to spin a flywheel inside the flashlight, attached to a small generator/dynamo, supplying electric current to an incandescent bulb or light-emitting diode.
Flash photolysis is a pump-probe laboratory technique, in which a sample is first excited by a strong pulse of light from a pulsed laser of nanosecond, picosecond, or femtosecond pulse width or by another short-pulse light source such as a flash lamp.
Flash Gordon is a pinball machine produced by Bally. It was the first split-level pinball machine from Bally, as well as the first game to use the "Squawk and Talk" sound board. It was also the second production Bally game with speech (Bally's 1980 Xenon was the first, utilizing a crude 'vocalizer' board set).
IM Flash has been able to devise 25-nm NAND chips with 193-nm immersion lithography, plus self-aligned double-patterning (SADP) techniques, where it is widely believed that it is using scanners from ASML Holdings NV and SADP technology. [3] In 2011 IM Flash moved to a 20 nm process– which was the smallest NAND flash technology at the time. [4]
A flash suppressor, also known as a flash guard, flash eliminator, flash hider, or flash cone, is a device attached to the muzzle of a rifle that reduces its visible signature while firing by cooling or dispersing the burning gases that exit the muzzle, a phenomenon typical of carbine-length weapons. Its primary intent is to reduce the chances ...
