Ricky Lim asked:
So just why should someone consider purchasing a pair of 4th generation night vision goggles over the other generations that are already available. Probably the biggest reason for choosing a 4th generation pair over say a 1st, 2nd or 3rd generation pair of night vision goggles is that the technology prescription online is much improved.
Certainly in the last 10 years the industry has seen a marked improvement on how well the image intensifiers work in order to produce a much clearer image to the user. Today with 4th generation goggles, a person is able to see much better quality images no matter what the light condition is like. This is why it now makes them the best performing of all night vision goggles that a person can actually purchase today.
Sometimes these types of goggles will be referred to as Generation 3+ goggles rather than Generation 4, but they do differ in two ways from the Generation 3 goggles.
4th Gen night vision goggles have an automatic gated power supply to them which now regulates the voltage of the photocathode, which allows them to instantly change to adapt to the lighting conditions that they are being used. Secondly they have either had the ion barrier removed or it has become much thinner which means that the noise and image being produced is much less distorted.
Because they have removed or made the ion barrier much thinner in 4th generation NVG's today as well as improving the gating system, this meant that the range of detection as well as the resolution at which the images are seen by the user is much improved. They are especially good as they can even be used when the light is extremely bad. As the ion barrier has either been removed or made thinner this results in more of the electrons being able to make their way through to the image intensifier which has resulted in all the images being produced of a much higher quality.
However, it is important to note that only a few manufacturers are actually currently producing these 4th generation night vision goggles and although they are presently being used by both military and law enforcement agencies, it may be some time before they become readily available to the general public. But even when available to the public, you can expect to pay a premium for them because of their advanced imaging capabilities.

Hooking up two NVIDI cards is called an SLI.
Hooking up two ATI cards is called crossfire.
So since you have NVIDI you would need an SLI certified power supply.

2 and if u are online, send me a mail telling in which class do u study
#Plasmonics refers to #quanta associated w/ longitudinal waves in #collective motion through matter as excited electrons. Sound familiar?<3
cool
Filed under: Hybrid, Lexus, In The AutoblogGreen Garage Lexus GS450h – Click above for high-res image gallery The love affair with batteries begins as a child. By the time your fifth Christmas rolls around, the moment you unwrap an electronic gadget your mind is already processing the thought, “Santa better have brought batteries…” Not only does that relationship continue as an adult, but what was once a simple tryst – “Mom, I need batteries for my Coleco Football” – has turned into a full-on romance (with every associated frustration) of our beloved battery-powered gizmos. Like, for instance, the Lexus GS450h. One of the sleepiest of sleeper sedans, its batteries aren’t responsible for keeping it running, only for supplementing the power of its 3.5-liter V6. And while hybrids have generally left us tepid, after a week with the Lexus, we’re almost ready to ask automakers for another Christmas gift: Put batteries in everything, and do it just like this.

You’re kidding.(:
If this gate valve is leaking at the top of the valve, all you have to do is Take the handle off the top, Undo the nut on top of the valve, and underneath this nut is what is known as a gland nut. Tighten this nut down just tight enough to still be able to turn the valve head. This should stop the leak . If you have to change the valve Then you have to turn off the water supply to this valve. You can fit a ball valve type of valve if you want to. Don't overtighten the nuts on the new valve. Just an extra quarter turn wheen they are tight.
