All of us want to have a peaceful and well-ordered life. But it is not always possible. You or your loved ones might be attacked any time. The very thought makes you uncomfortable, doesn?t it? It?s better to learn to defend yourself before it is too late.

When it comes to self defense, there are a variety of products that you can opt for, like pepper sprays, personal alarms, and electronic control devices. In my opinion, the Taser C2 Personal Protector is the best weapon to protect yourself. Believe me, with this product, you will be at peace, knowing that you and your family are completely safe.

This Taser Personal Protector is slim enough to slip into your purse or your pocket, so you can carry it anywhere. This Electronic Control Device (ECD) makes use of the Neuromuscular Incapacitation (NMI) technology, which affects the sensory and motor functions of the nervous system and impairs the muscle control temporarily. So however powerful your attacker maybe you?ll have enough time to run for cover.

Unlike other self-defense systems, the C2 Taser Gun doesn?t have any specific target area. So, you can use it anywhere on the body to get the same effect. This feature is extremely useful when you are under any threat.

This Taser Personal Protector uses the same technology used in law enforcement models. A non-lethal device, it works even at a distance of 15 feet, giving you enough space to protect yourself from the attacker. The Taser C2 Personal Protector increases your security options further with an integrated LED light and laser sight. It has built-in LED lights for use in the dark so you?ll feel safe even in the dark. Aim accurately with the laser sight.

Another very useful feature is the Anti-Felon Identification (AFID), which prevents the misuse of the Taser Stun gun . All in all, the Taser C2 Personal Protector will definitely make you feel safe.

A fuel cell is an electro chemical energy conversion device, which produces electricity from external supplies of fuel (on the anode side) and oxidant (on the cathode side). These react in the presence of an electrolyte to produce energy.

Since a typical fuel cell produces less than one volt, in practical application cells are ’stacked’ in parallel to create a useful voltage. Thus a typical fuel cell is made up of many thin sheets, usually of stainless steel, which must be welded together to form the fuel cell stack.

Welding of the plates is by far the most time consuming process involved in the manufacture of fuel cells – there is about one meter of welding required for every single plate in every single fuel cell stack – that is about 400m of welding for each eco-car. Optimising the welding process offers the opportunity to make significant savings in the cost of production of fuel cells.

The issues here are all related to the difficulty of achieving a small, clean, reliable weld at viable production speeds using traditional laser welding techniques. To solve these problems, the leading-edge manufacturers are now looking to fibre laser welding technology.

The key advantages of fibre lasers over other laser technologies are its high beam quality, energy & power stability, giving higher power density and a greater breadth of control, as well as its low total cost of ownership. The high beam quality of the fibre laser enables the beam to be focused to a small spot with a correspondingly high energy density. This enables very fast and efficient processing, yielding welds with a high aspect ratio. Compared with other laser sources, the fibre laser can produce welds with significantly lower heat input resulting in less distortion of the welded plates. The high energy stability, typically +/-0.5%, gives welds of consistent profile and penetration with extremely low levels of weld root porosity.

It is recognised that other laser technologies are capable of making such welds, but the fibre laser offers a solution that welds faster with higher quality at a lower operational running cost. “We believe that the cost-performance capability of a standard 200W fibre laser will act as an enabling technology in the battle to drive down production costs of tomorrows fuel cells” said John Tinson.

The fuel cell plate requires a high aspect ratio weld (typically 3:1 or 4:1) in order minimise heat input to the plate and keep distortion to an acceptable level. The beauty of the fibre laser is that it readily achieves this with spot sizes of less than 200 m. As a result, distortion of the plates, a potentially cumulative problem when the plates are stacked, can be minimised.

Metallographic analysis of ‘key-hole’ and high aspect ratio welds often reveals problems with weld porosity, particularly in the root of the weld. In the fuel cell application the integrity of the weld is vitally important and a fully hermetic seal is a prime requirement. A poor quality weld could lead to serious performance problems over the life of the fuel cell, or even leakage of hydrogen or other fluids. Experience has shown that the fibre laser, with its exceptionally high power density at the work-piece, is particularly good producing consistently reliable, non-porous welds.

Another problem noted by some manufacturers using YAG or CO2 lasers is the possibility of ‘humping’ of the weld, when the laser is operated at high production speeds. This is the phenomenon whereby the inherent fluid instability of the melt pool at high weld speed creates a ‘hump’. It is seen as a problem by some manufacturers because it can limit production speed, but it is not a problem with a standard 200W fibre laser, even at speeds of up to five or six metres / minute it can produce over 2,500km of weld per annum.

In a production environment fibre lasers have a reputation from extremely high up times and have no operational consumables, unlike other laser sources such as Nd:YAG lasers that require a periodic change of flash lamps or CO2 lasers which need supply of consumable gases. Additionally the high electrical efficiency of fibre lasers – up to ten times more efficient in power consumption than Nd:YAG equivalents mean that they offer significantly lower running costs. They can be used for welding ‘on demand’ unlike some other types of lasers with no need for warm-up, further reducing energy consumption and run through scrap. As fibre lasers are sealed units with no lamps that need changing or mirrors to realign, they have a very low maintenance overhead, yielding savings of thousands of

With the forthcoming TUSK add-on kit, an M2 or an Mk 19 grenade launcher can be mounted on the CROWS remote weapons platform (similar to the Protector M151 remote weapon station used on the Stryker family of vehicles). 2. A 7.62 mm M240 machine gun in front of the loader’s hatch on a skate mount. 3. A 7.62 mm M240 machine gun in a coaxial mount. The coaxial MG is aimed and fired with the computer fire control system used for the main gun. The turret is fitted with two six-barreled smoke grenade launchers (USMC Abrams use an eight-barreled version). These can create a thick smoke that blocks both vision and thermal imaging, and can also be armed with chaff. The engine is also equipped with a smoke generator that is triggered by the driver.

The Abrams also has provisions for storing an M16 rifle or M4 carbine inside the crew compartment for when they have to leave the protection of the tank under potentially hostile conditions, plus Abrams crews always carry personal side arms, the M9 Beretta pistols. The Abrams is equipped with a ballistic fire-control computer that uses data from a variety of sources, including the thermal or daylight Gunner’s Primary Sight (GPS), a laser rangefinder, a crosswind sensor, a pendulum static cant sensor, data on the ammunition type, ammunition temperature, and a muzzle reference sensor (MRS) that determines barrel drop due to gravity and temperature. The fire-control system uses this data to compute a firing solution for the gunner. The ballistic solution generated ensures a hit percentage greater than 95 percent at nominal ranges. Either the commander or gunner can fire the main gun.

Additionally, the Commander’s Independent Thermal Viewer (CITV) can be used to locate targets and pass them on for the gunner to engage while the commander scans for new targets. In the event of a malfunction or damage to the primary sight system, the main and coaxial weapons can be manually aimed using a telescopic scope bore sighted to the main gun known as the Gunner’s Auxiliary Sight (GAS). The GAS has two interchangeable reticles; one for HEAT and one for APFSDS ammunition.
