Calvin Klein USB Sunglasses for Geeks

Geeks around the world can look real cool now, as Calvin Klein has given them something they just can't resist. The company has introduced the USB sunglasses, which would be keeping the data safe and giving a stylish look on the way.The glasses are really good looking and the best part is that the USB has been nicely hidden in the right arm. I at first thought, that the glasses would look hideous with a USB drive. But after watching the glasses, I have to admit its a cool design. The USB carries a space of 4GB, yes you heard me right. It would have been so much better, if Calvin Klein put another 4GB USB in the other arm !!.

Power Saving Switch System Design

Saving electricity can become a problem for busy families, as kids just forget to switch OFF lights when there is no need of it. Researchers at the University of Standford have come up with a ingenious solution to this very problem. They have designed a system in which for example you wish you switch ON another light the switch will get a bit rigid and resit your push. This is actually an indication that there are enough switches already ON in your house therefore you should first switch them OFF to reduce the load stress.

Here is a demonstration video of the designed system:

Keep Waking with USB Wink Glasses

Its hard not to get sleepy after you work constantly, specially when you are on the laptop making some projects etc. The USB Wink Glasses are simply great, if you want to work late and not to get drowsy.All you need to do is wear the wink glasses with your existing spectacles. It would count the number of times you wink and if it finds that you are not blinking, it would fog the screen causing you to blink. A simple yet very effective idea to help people who find it hard to stick their eyes right place while working.But, damn i couldn't understand one thing which is that "what would people do who don't wear specs? ". This makes this gadget specific to those people who wear specs.

Eco-Friendly No Driver Taxis for Heathrow Airport

Finally the era of no driver vehicles has arrived, as we only need to tell the vehicle where to go. The out of the space looking buble taxis have been designed for passengers, to go places where they want with the help of a touchscreen interface. Heathrow Airport has bought 18 of such taxis to take their passengers from the car parking to the Terminal 5.



The idea of it comes from Professor Martin Lowson who has a good experience in space travel. The taxi was showed to the world at the Science Museum in London latetly. It has the capacity of taking 4 passengers at a time, with a top speed of 25miles/hour.

The taxi has a overall nice design which gives a very futuristic look. Moreover, the taxi is an eco-friendly vehicle as it runs on batteries so no fumes would be seen keeping the environment clean and clear. Heathrow Airport would be using these taxis by next year.

About The Harrier Jump Jet!

THE HARRIER JUMP JET

The Harrier Jump Jet is the worlds only vertical take off and landing jet fighter. It was developed by the British in an era of financial cutbacks which saw the end of the large Royal Navy Aircraft Carriers. It can use airfields on land or fly from smaller aircraft carriers at sea and is flown by the best US and British pilots. It combines the best aspects of a helicopter with those of a fighter jet. For example, the world speed record for a helicopter is 249 mph (Linx helicopter) whilst the Harrier can fly at 730 mph.

The Harriers most famous feature is its vertical take off and landing capability. Although the Harrier has one jet engine (The Pegasus) it has four nozzles that direct the jet engine thrust downwards for vertical lift. (Diagram 1)

Once airborne the nozzles are slowly revolved so that the plane moves forward. (Diagram 2)

Vertical take off and landing uses an enormous amount of skill on the part of the pilot and also a large amount of fuel. The Harrier can only hover for 90 seconds, in this time it uses 150 gallons of water to keep the engine cool.


To save fuel a simple ramp allows the plane to take off on a very short runway. This is used by the Royal Navy Carriers. The planes appear to hop into the air.

Vents at the ends of each wing can be used to direct some of the thrust and this allows the pilot to move the plane left, right, forwards and backwards - whilst hovering.

How Does Galileo's Telescope Work?

A Bit of History:

Galileo Galilei didn’t invent the telescope. Even so, it was when the great Italian scientist pointed a telescope toward the night (and even the day) sky that the world changed forever.

Galileo discovered the planet Venus has phases, just like the Moon. No one could have known that until the telescope was invented. Galileo saw that the Moon had craters and mountains, and that the Sun had moving black spots on its face. He also discovered four new moons circling the planet Jupiter.

All these discoveries helped show that the Earth is not the centre of the universe, that the planets orbit a changing and imperfect Sun, and that the planets are other worlds, something like the Earth but very far away. With his telescope, Galileo literally remade the world.

Galileo’s telescope was a refracting telescope. Isaac Newton, who was born the same day Galileo died, invented another kind of telescope, called a reflecting telescope. Reflecting telescopes use mirrors instead of lenses to make faraway things look bigger. Reflecting telescopes can be made much more powerful than refractors, and Newton’s invention paved the way for all the great telescopes to come.

How It Works:
Refracting telescopes depend on one amazing fact. As light passes through glass, it slows down. Slowing down a light beam makes it bend. Why? Imagine you’re pulling a wagon along a sidewalk, when the wheels on one side slip off into the grass. The wheels turn slower in the grass than they do on the sidewalk, and the wagon moves toward the grass. In the same way, when a light beam passes through a glass lens inside a telescope, it moves toward the lens. When the light beam comes out the other side, it’s bent!

The shape of the lens means light near the top of the lens is bent down and light near the bottom of the lens is bent up. Somewhere inside the tube the light beams cross, but before they can spread out again the eyepiece lens bends the light beams again and sends them to the eye.

Because the light beams cross, the image ends up upside-down. This doesn’t matter much when you’re looking at Mars or the Moon (remember there’s no real up or down in space), but refracting telescopes used to see objects here on Earth often have another set of lenses to flip the image right-side up again.

Refracting telescopes are simpler than reflecting telescopes, but they have an important limitation. Remember that the light passing through the glass lens gets bent. It turns out that different colours are bent different amounts, and that causes the light to become unfocused. Isaac Newton solved this problem by replacing the lenses with mirrors.

When light hits a mirror, it doesn’t bend. Instead, it bounces off. Just like a ball bouncing off a wall, a light beam comes off a mirror the same way it comes in. In other words, the angle in equals the angle out. And that rule is true for all the light, no matter its colour.

The primary mirror in a reflecting telescope is curved just the right amount to bounce all the light onto the secondary mirror. From there, the light passes through the eyepiece lens, which bends the light into the eye.

How Speakers Work

How Speakers Work

Driver Types:

In the last section, we saw that traditional speakers produce sound by pushing and pulling an electromagnet attached to a flexible cone. Although drivers are all based on the same concept, there is a wide range in driver size and power. The basic driver types are:

1.Woofers
2.Tweeters
3.Midrange

Woofer

Tweeter

Midrange

Woofers are the biggest drivers, and are designed to produce low frequency sounds. Tweeters are much smaller units, designed to produce the highest frequencies. Midrange speakers produce a range of frequencies in the middle of the sound spectrum.

And if you think about it, this makes perfect sense. To create higher frequency waves -- waves in which the points of high pressure and low pressure are closer together -- the driver diaphragm must vibrate more quickly. This is harder to do with a large cone because of the mass of the cone. Conversely, it's harder to get a small driver to vibrate slowly enough to produce very low frequency sounds. It's more suited to rapid movement.

Cyber Crooks Targeting Windows XP-Based ATM Machines

You may want to think twice the next time you drive up to an ATM machine and blithely insert your bank card into the nondescript machine and plug in your PIN number, because a gang of cyber crooks are now targeting ATM machines.

European hackers are targeting ATM machines that run on Windows XP with a new malware program that provides full access to a user’s pin codes and other personal data.
Trustwave’s SpiderLabs analyzed the unique malware program discovered in nearly 20 ATM machines in Eastern Europe and have never seen anything like it. All of the infected machines were found to run on Windows XP.

The hackers used a simple dropper file to install and activate the malware virus. A dropper file is a tiny infected, standalone program that drops a virus into a system. One the dropper installs and activates the malware program; the hackers obtain full access to the private memory space of all of the transaction-processing applications on ATMs.

The malware program works by capturing the magnetic strip data and PIN codes. The cyber crooks then access the personal data by inserting a specially designed card into the ATM, where they can pull up their own customized user interface.

Once this occurs, the hackers have effectively hijacked the ATM and you can say goodbye to your money.

Cyber security experts have issued previous warnings to banking institutions regarding the risk of using a Windows based system to run ATM machines. Some have even called the practice stupid.

Many ATMs now run Windows operating systems connected to a large group of servers over an IP network, exposing personal data to theft, and denial of service attacks.

Many systems don’t even encrypt data as it travels through the network, exposing card numbers, card expiration dates, transaction amounts, and account balances in plain text, making it easy for determined cyber crooks to harvest customer’s data.

The virus experts of SpiderLabs believes the cyber crooks are using Eastern Europe as a testing ground for their malware program, before they launch the virus to infect ATMs in the United States and other countries.

How Wind Power Works?

It's hard sometimes to imagine air as a fluid. It just seems so ... invisible. But air is a fluid like any other except that its particles are in gas form instead of liquid. And when air moves quickly, in the form of wind, those particles are moving quickly. Motion means kinetic energy, which can be captured, just like the energy in moving water can be captured by the turbine in a hydroelectric dams. In the case of a wind-electric turbine, the turbine blades are designed to capture the kinetic energy in wind. The rest is nearly identical to a hydroelectric setup: When the turbine blades capture wind energy and start moving, they spin a shaft that leads from the hub of the rotor to a generator. The generator turns that rotational energy into electricity. At its essence, generating electricity from the wind is all about transferring energy from one medium to another.

Wind power all starts with the sun. When the sun heats up a certain area of land, the air around that land mass absorbs some of that heat. At a certain temperature, that hotter air begins to rise very quickly because a given volume of hot air is lighter than an equal volume of cooler air. Faster-moving (hotter) air particles exert more pressure than slower-moving particles, so it takes fewer of them to maintain the normal air pressure at a given elevation (see How Hot Air Baloons Work) to learn more about air temperature and pressure). When that lighter hot air suddenly rises, cooler air flows quickly in to fill the gap the hot air leaves behind. That air rushing in to fill the gap is wind.

­If you place an object like a rotor blade in the path of that wind, the wind will push on it, transferring some of its own energy of motion to the blade. This is how a wind turbine captures energy from the wind. The same thing happens with a sail boat. When moving air pushes on the barrier of the sail, it causes the boat to move. The wind has transferred its own energy of motion to the sailboat.

BMW Z4 Coupe

Munich. Following strong consumer reaction to the concept Z4 Coupe at the 2005 Frankfurt and Tokyo Auto Shows, BMW has confirmed that both the Z4 Coupe and an M version, the M Coupe will enter series production.

Visitors in Frankfurt and Tokyo were captivated by the car’s stylish body with its unique silken matte finish, tailored in the very best style of a classic sports coupe. While the driving dynamics potential of the vehicle was clear in its strong, purposeful lines, equally appealing to visitors was the striking interior design.

To be produced in Spartanburg, S.C., the first vehicles will be delivered to customers as early as June 2006.

The proven 255 horsepower (U.S. SAE net) in-line 6-cylinder engine with its high output and lightweight magnesium and aluminum construction promises superior agility and high performance. It not only catapults the Z4 Coupe to the top of the international competitive field but is also demonstrates the enormous performance capacity of the fundamental BMW Z4 Roadster concept – which forms the basis of the coupe.

BMW is also working to produce a high-end variation as quickly as possible and the result will be the return of the M Coupe, based on the new Z4 Coupe. Powered by the exciting 3.2-liter high-rpm engine, familiar from the BMW M3 and winner of many international awards, it will also come out in June 2006.

FMG9 Folding Machine Gun

The concept of a discreet, foldable submachine gun is at least two decades old. Legendary gun designer Eugene Stoner developed one in the 1980s, but Magpul Industries made news this past March with its own updated take on the lethal cult classic. The FMG9, short for Folding Machine Gun, looks like some sort of toolbox with a flashlight mounted on top.

One moment, that flashlight is in your eyes, and one moment later—one very pregnant, James-Bond-by-way-of-Cyberpunk moment—and you're being fired at by a 9mm submachine gun. It's a quicker transition than anything Stoner was able to pull off, and that could make the weapon an effective tool for lightning raids on terrorist hideouts where surprise could play a major part. The gun also has an integrated laser sight, and can be carried without the handle and flashlight, for a sleeker, more pocketable profile.

Corner Shot Launcher

The Corner Shot is a brutally simple contraption: a modified gun that, thanks to a hinged frame, under-the-barrel camera and handy video screen, allows the user to shoot around corners. Currently, there are three versions available, each with a different weapon at the business end of the frame—a pistol, a compact assault rifle or a 40mm grenade launcher. The device is designed for urban environments, where the ability to peek around corners with impunity is useful, but being able to open fire while behind cover is even better.

With the Corner Shot Launcher, the concept is the same, but the result is less subtle. Essentially a sideways-firing rocket launcher, it allows the user to aim with the same kind of integrated camera and video screen, and fire a massive 60mm round into an enemy vehicle or reinforced position, such as a bunker. This device, which could be an overwhelming weapon in urban engagements, is a collaboration between Israeli and German defense firms.

SAR-21

While the United States has repeatedly—and spectacularly—failed to replace the aging M-16, Singapore has been using a newer and possibly better-performing assault rifle since 1999. The SAR 21 replaced Singapore's licensed version of the M-16, and has gained a reputation among gun experts as one of the best “bullpup” assault rifles—where the action and magazine are behind the trigger—on the market. It has a smaller overall profile than the M-16, without sacrificing barrel length (the shorter the barrel, the less accuracy at longer ranges) and significantly more manageable recoil, due in part to the weapon's center of balance. The recoil tends to drive directly back against the firer, instead of pushing the barrel upwards.

All of this is useful in an assault rifle, but particularly for urban warfare, where more compact weapons are crucial to maneuvering indoors, and where close-range, fully-automatic fire is more common. The SAR 21 has a Kevlar cheek plate to deal with chamber explosions occurring next to the user's face, a regular safety issue for bullup weapons. It's also one of the few assault rifles in the world equipped with an integrated laser aiming device.

Apache Attack Helicopter

Apache AH-64 military attack helicopter is one of the most respected combat helicopters ever created. Two seate r with four blades in the main and tail rotor was seen in action in Panama, Gulf war, Afghanistan and Iraq. First one produced in 1984 and ever since it was one of major air to land, air to air weapons in U.S. Army.Designed by Hughes Helicopters for Army's Advanced Attack Helicopter program.

Through many years AH-64 got many improvements. Latest is AH-64D Apache Longbow which is currently in use of U.S. Army.

AH-64 variations:

AH-64A is the original attack helicopter. Two seater with four blades combined with two turbo-shaft engines. 30mm M230 chain gun in combination with AMG Hellfire anti-tank missiles, Hydra 70 unguided rockets and air to air missiles for defense AIM-92 Stinger.

AH-64B upgrade from AH-64A brought newly developed GPS system and other electronics including improved navigation system and new radios. This model was soon cancel and all new gadgets were built in previously mentioned AH-64A.

AH-64C and AH-64D both quite similar and brought a lot of new improvements in sensor and weapon system. Helicopter also got a new more powerful engines. The key improvement was a small dome installed over the main rotor which housed FCR - "Fire control radar."

Sea Apache was a modified AH-64A for Navy purposes.

Design and armaments:

AH-64 power comes from two General Electric T700 turboshaft engines. The power from engines is transferred in four blades in the main rotor and in the tail rotor. There are two seats, one for a pilot and copilot(gunner) which takes care of firing weapons. Its armor provides some safety and can sustain hits from 23mm gunfire.AH-64 is armed with the main 30mm M230 Chain gun, which aim is in the gunner's helmet mounted display. Other weapons are stored in its stub-wing pylons. Usually it is armed with AGM-114 Hellfire missiles used for ground targets, Hydra 70 unguided 70mm rockets and AIM92 air to air missiles.

Sophisticated radars and other electronics such as GPS, Target acquisition and designation system combined with pilot night vision system allow this steeal bird to operate in combat during the day or night.

Today AH-64 is used in countries all over the world including Egypt, Greece, Israel, Japan, Kuwait, Netherlands, Saudi Arabia, Singapore, United Arab Emirates, United Kingdom and United States.
