How would be if without hurting or killing people we would
able to control over un-civilized mob or anti-social elements .
It is possible The Active Denial System (ADS) a non-lethal,
directed-energy weapon developed by the U.S. military to control un-wanted rage
of mob.
The weapon is also called the heat ray, since it
works by heating the surface of targets, such as the skin of targeted human
subjects.
The ADS was
deployed in 2010 with the United States military in the Afghanistan war
The ADS is currently only a
vehicle-mounted weapon, though U.S. Marines and police are both working on
portable versions
How it works ??
It works
same as of micro-wave, but the difference is we do not have to burn people
nevertheless we have to provide burning sensation.
The ADS
works by firing a high-powered beam of 95 GHz extremely high frequency waves at
a target, which corresponds to a wavelength of 3.2 mm. The ADS millimeter wave
energy works on a similar principle as a microwave oven, exciting the water and
fat molecules in the skin, and instantly heating them via dielectric heating.
One significant difference is that a microwave oven uses the much lower
frequency (and longer wavelength) of 2.45 GHz. The short millimeter waves used
in ADS only penetrate the top layers of skin, with most of the energy being absorbed
within 0.4 mm (1/64"), whereas microwaves will penetrate into human tissue
about 17mm (0.67").
The ADSĘžs
repel effect in humans occurs at slightly higher than 44°C (111°F), with
first-degree burns occurring at about 51°C (124°F), and second-degree burns occurring
at about 58°C (136°F). In testing, pea-sized blisters have been observed in
less than 0.1% of ADS exposures, indicating that second degree surface burns
have been caused by the device. The radiation burns caused are similar to
microwave burns, but only on the skin surface due to the decreased penetration
of shorter millimeter waves. The surface temperature of a target will continue
to rise so long as the beam is applied, at a rate dictated by the target's
material and distance from the transmitter, along with the beam's frequency and
power level set by the operator. Most human test subjects reached their pain
threshold within 3 seconds, and none could endure more than 5 seconds.
Problems using ADS
The problems
regarding using ads is If the beam is
fired through rain, snow, fog, or mist, the painful sensation turns into a
"warm and comfortable" sensation. The problem is that microwaves and
lasers are broken up by these forms of precipitation.
And if individual wears
thicker clothes it decrease it effectiveness.
