This gun is small but a very useful non-lethal weapon that can be very effective in tackling a restless mob. The gun can be termed as an anti-violence product as it fires just pepper powder, rubber bullets and paint bullets. The gun can also fire a 30KV electronic pulse for incapacitating someone at 3 metres through 1 inch of clothing and can stun someone for few seconds with its powerful flashlight. Moreover the TW-ESG-Z1 has a safety wrist strap that disables the gun if an attacker takes it from you.

One look at these guns and you would forget that they could kill. Far from their original purpose, these guns do not seem to have even the ‘looks that kill.’ However, they do catch the fancy of art collectors. The shotgun with the viewfinder aside, the rest of the guns look like they have been transported from a different age or possibly, from a different planet altogether. Nevertheless, they do have the looks to grab attention. If you are a lover of ‘all things unique’, these guns are for you!!! Go get’em….

The largest shotgun I have ever heard or seen is a 12 gauge shot gun used by cops that is capable of decapitating your head with just one shot. But, here’s the big daddy of all shotguns. This one takes about two people to move the gun from one place to the other.

Since the gun is so heavy, it has to be mounted on the punts. Thus, the world’s largest shotgun is also known as a Punt gun. When mounted, the gun almost looks like a cannon. According to the reports, a single shot from the Punt can wipe out about 50 to 100 ducks.

The embedded video shows the big guy lifting the heavy gun. I guess it would be better if we call it cannon instead of a gun. Due to the weight of the gun, the recoil is huge. So, you have to really watch out while firing. Basically, you can take out a whole case of clay targets stacked on a board with this big and long punt gun. The next longest model would be the shotgun like pellets assembled by the Indonesians. The pellets can fill about 50 Olympic swimming pools.

To eliminate heat-illness this thermal vest uses a combination of air, liquid and new applications of old technologies such as converting paraffin wax into liquid in chambers within the vests to absorb heat from the body.

The test reveals that troops wearing heavy and dense biological and chemical protection frequently suffer heat-illness that can seriously hamper their judgment and decision-making process. The illness can even result to death in extreme climates.

Though the test is yet in its early stages of development, it is projected to be used within two years by American troops working in extreme hot climate, especially Iraq where temperature can reach as high as 50 degrees celsius.

The acoustic source and target can be located in unconfined underwater space and at a distance of at least 100 m apart.

The underwater cavitation could be used in superfast sub and missiles. The idea is pretty different i.e. using acoustic energy instead of any bombs or missiles to destroy the targets. It is no doubt a new pin on the idea of underwater weapons.

If we put some light on choppers worst disasters from the day the war began in Iraq, the reports reveals that somewhere around 28 people’s died in different attacks due to helicopter’s crash via RPG(Rocket propelled grenade) artillery. Now, to surmount the RPG guns New Jersey-based inventor Richard Glasson, has developed the first-ever anti-RPG system for aircraft which is a volley of nets that catch the grenades before they hit.

To develop this high-tech innovation Glasson a chief engineer at Control Products, a company that designs sensors for aerospace and defense and who has also worked on sensors that protect gearboxes from overheating on the president’s Marine One choppers and in jet engines on most commercial airliners, was inspired by the Mark Bowden’s best seller Black Hawk Down which gives an account of the 1993 killing of 18 U.S. soldiers in Somalia when an RPG brought down their chopper. Glasson said:

I couldn’t believe that such a low-tech weapon could take down a several-million-dollar aircraft,’ that’s a spectacular outcome for a 40-year-old technology.

It is noteworthy that other countermeasures, such as radar jammers and flares are also proved worthless against hand weapons like RPGs. Defense companies are also working on some new systems that would fire projectiles at the grenades to demolish them and according to the Glasson this new system will be just ‘like hitting a bullet with a bullet’.

Therefore, instead of supporting the above mentioned concept to combat RPG’s he advised defense, as RPGs targets are amazingly straightforward and far much slower than the heat-seeking missiles he developed a new system that would block or at least avert the grenades before they hit the chopper.

Normally, RPG takes four to six seconds to explode when fired (unless it hits solid object- then it detonates on impact) it doesn’t explode after being fired (unless it hits a solid object-then it detonates on impact) but Glasson’s this new system enables chopper radar to calculate the speed and trajectory of an incoming grenade within milliseconds .

Half a second later, pods of launch tubes bundled on the helicopter aim and fire between one and eight unguided yard-long rockets on an intercept course with the grenade. The aim of rocket doesn’t have to be precise because each drags a braided steel-cable parachute woven with Kevlar and in the next second, these fast-opening chutes blow-up to form a series of six-foot-wide bombproof nets to catch the grenade and to drag it to the ground.

However, Glasson is still not sure about all the functioning of its new system until his will test the system on a real helicopter for which he will need the support of Pentagon or some of the contractors. Pentagon on the other hand does not seem to be much interested in the system, they told the developer that they are much interested in a laser based protection system, which is years from development. Glasson still is not losing hope, he is of the belief that the recent crashes will convince Pentagon to give at least one try to the system developed by him.

All the best Glasson.

Now, as this gun encompasses almost everything that I can imagine for survival and assistance in the battlefield, I will like to appreciate that anonymous designer for keeping up the good work to make it world’s first machine-gun of its type.

To build this biosensor Danny Dhanasekaran and his colleagues genetically engineered a yeast strain with rat olfactory signaling machinery and thereafter by linking it to the expression of green fluorescent protein.

Associate Professor of Biochemistry at Temple’s Fels Institute for Cancer Research and Molecular Biology Danny Dhanasekaran said:

We suspected that harnessing the potential of the olfactory system, which can detect innumerable chemical agents with unparalleled sensitivity and selectivity, would be of immense value in the detection of environmental toxins and chemical warfare agents even at sublethal levels

The yeast cells are then cloned individually with rat olfactory receptors and when the olfactory receptor “smells” the odor of DNT or an ingredient in the explosive TNT, the biosensor turns fluorescent green.

The forecast also reveals that day is not far when this bionic nose will be used to detect other hazardous gases and landmines.

The helmets that will scare enemy pilots at first sight with its robotic looks encompasses:

• Binocular Wide Field-of-View

• Highly accurate head tracking hardware and software

• Integrated day/night capability with sensor fusion

• Digital image source for helmet vision displayed symbology

• Custom helmet shell, liner and suspension system for lightest weight, optimal C.G. and maximum pilot - comfort.

The HMDS will also allow F-35 pilots to keep an eye on different targets concurrently with most possible angles without turning their heads, thanks to the Vision Systems International, a company who developed this robotic device to enable pilots to work more smartly to accomplish their assigned targets.

The main objective of this programme of DARPA is to create low-cost medical sensor systems to support DoD missions and to compute the snowballing effects of blasts exposure.

This new programme will also assist to combat medical care, patient triage and physiologic monitoring to maintain physiologic performance of soldiers but it is also predicted that to meet these goals the programme will demand furthering print-on electronics and ink formulation technologies. So therefore, to eliminate these demands DARPA is nowadays busy in receiving proposals to exploit the novel properties of print-on electronics to construct these medical monitoring systems.

The agency has two principle systems to achieve, firstly to develop an helmet (or body-mounted) blast dosimeters and secondly, to develop basic patient physiological monitoring devices to measure heart rate, body temperature, pulse, respiration and blood oxygen saturation.

Each system will come bundled with a patch-like sensor device and a monitoring unit to communicate with the sensor tape patch.

But along with these systems other ground-breaking medical devices that integrate print-on electronics and related technologies can also be proposed, might be for future amalgamation of all the technologies and to create an avant-garde technology that might encompass all the systems in one single sensor.
