Lytro camera ignites a digital revolution


A New Way to Take & Experience Pictures
The Lytro Light Field Camera represents the most significant shift in photography since the transition from film to digital.





The device records all of the light falling on its sensor without running it through processes such as colour balancing or sharpening and these can be applied later on a computer.





Similarly, by recording the light field passing through many tiny micro-lenses in the Lytro, the action of merging these to create a single flat image can be applied as a post-production effect.





"Light field photography was once only possible with 100 cameras tethered to a supercomputer in a lab," the BBC quoted Ng as saying.





According to the company, Lytro's image sensor is capable of capturing 11 megarays of data, whereas the feature of producing 3D images will be added at a later date. (Text :ANI)

Qaeda bombmaker designed latest stealth range to conceal in Cameras, Hard Drives and Pets


Washington, May 10 (ANI): A Saudi Arabian bomb maker has revealed the latest Al Qaeda bombs are designed so that they can be surgically implanted in terrorists, pets and computer hardrives.
Ibrahim al-Asir, an undercover agent with Saudi intelligence and the CIA, has created many hard-to-detect bombs inside cameras, computers and even household pets that get past security screening easily.
The Al Qaeda bomb designs emerged after al-Asir, was caught during a sting operation in Yemen.
"It makes him (al-Asir) dangerous and it's clear that we want to make sure that he doesn't have the opportunity to A, to continue to do, to build any device whatsoever, or impart his knowledge to anyone else who wants to build these devices," ABC News quoted Mike Rogers, Chairman of the House Homeland Security Committee, was reported, as saying.

India clears $660 mn deal for artillery guns


New Delhi, May 11 (IANS) The Indian Army got a shot in the arm Friday with the defence ministry clearing its long-pending $660 million (Rs.3,000 crore) proposal to buy 145 ultra-light howitzer guns to add teeth to its ageing inventory.
This is the first time the army is buying artillery guns in 27 years, since the Bofors guns payoff scandal broke out in the late 1980s, defence ministry sources said here.
The Defence Acquisition Council (DAC), headed by Defence Minister A.K. Antony, cleared the deal for the M777 BAE Systems guns that will be bought through the Foreign Military Sales (FMS) route of the US government.
The purchase comes in the wake of Indian Army chief Gen. V.K. Singh writing to Prime Minister Manmohan Singh in March highlighting the gaps in its preparedness.
Being light in weight, the 155mm 39-calibre guns can be easily airlifted and will be deployed in the high altitude mountainous areas in the northeast and in the Ladakh region of Jammu and Kashmir bordering China.
A couple of weeks ago the defence ministry had approved infrastructure development projects in the northeast, including strategic roads and rail lines that will enable easy and quick mobilisation of troops.
The DAC cleared the M777 gun following a favourable report by a committee headed by Defence Research and Development Organisation (DRDO) chief V.K. Saraswat that studied the suitability of the weapon system.
The army had recommended the gun following a series of rigorous trials.

Soon, air-powered cars to debut in India


Washington, May 10 (ANI): India-based Tata Motors has said that it has tested two cars that can run on compressed air, and that the next step is setting up the manufacturing plants to actually build them.
In 2007, Tata Motors signed a licensing deal with Motor Development International, a French design firm.
Compressed air engines aren't a new idea. The first models were proposed more than a century ago, and they were used in the mining industry for decades before electric motors became commonplace.
Even now, compressed air powers all kinds of tools, notably the pneumatic impact wrenches in auto body shops.
A compressed air car engine works in a way similar to the internal combustion version - Fuel forces pistons to turn a crankshaft and power the car. The difference is that in a compressed air engine, the pistons are moved by air and not gasoline.
Researchers in Sweden have experimented with single-cylinder engines of this type.
The only problem is power. Air compression alone only gets a car moving to about 30 to 35 miles per hour. So to supplement that, the car could take in more air as it moves faster, using an onboard air compressor.
The air compressor could be electric or, more likely, gasoline-powered. But even that would reduce emissions a lot, since the gasoline engine wouldn't be running at lower speeds.
Range is also an issue. Like all vehicles, an air-powered car can drive only as far as the amount of fuel in its tank. And storing compressed air requires "fuel" tanks that are stronger than steel to contain the thousands of pounds per square inch necessary.
On the bright side, compressing air in such a tank is a lot less dangerous than natural gas or hydrogen. Then there is the issue of filling the car's tank, most air compressors would take at least a couple of hours to do that.
Tata seems to be the only manufacturer that has committed to actually building an air-powered car. Honda unveiled an air-powered concept car in 2010, and a company called Zero Pollution Motors had promised to deliver one to the United States, but that was two years ago.
If Tata is successful, it will go a long way toward reducing emissions in India-and perhaps freeing cars from fossil fuels completely. (ANI)

NASA's Spitzer detects light of alien 'Super-Earth'


Washington, May 9 (IANS) NASA's Spitzer Space Telescope has detected light emanating from a "super-Earth" planet beyond our solar system for the first time.
"Spitzer has amazed us yet again," said Bill Danchi, Spitzer program scientist at NASA Headquarters here. "The spacecraft is pioneering the study of atmospheres of distant planets and paving the way for NASA's upcoming James Webb Space Telescope to apply a similar technique on potentially habitable planets."
The planet, called 55 Cancri e, falls into a class of planets termed super Earths, which are more massive than our home world but lighter than giant planets like Neptune. The planet is about twice as big and eight times as massive as Earth. It orbits a bright star, called 55 Cancri, in a mere 18 hours, according to a NASA statement.
Previously, Spitzer and other telescopes were able to study the planet by analyzing how the light from 55 Cancri changed as the planet passed in front of the star. In the new study, Spitzer measured how much infrared light comes from the planet itself.
The results reveal the planet is likely dark, and its sun-facing side is more than 2,000 Kelvin (3,140 degrees Fahrenheit), hot enough to melt metal. The new information is consistent with a prior theory that 55 Cancri e is a water world: a rocky core surrounded by a layer of water in a "supercritical" state where it is both liquid and gas, and topped by a blanket of steam.
"It could be very similar to Neptune, if you pulled Neptune in toward our sun and watched its atmosphere boil away," said Michael Gillon of Universite de Liege in Belgium, principal investigator of the research, which appears in the Astrophysical Journal. Brice-Olivier Demory of the Massachusetts Institute of Technology, Cambridge, led the study.
The 55 Cancri system is relatively close to Earth, at 41 light-years away. It has five planets, with 55 Cancri e the closest to the star and tidally locked, so one side always faces the star. Spitzer discovered the sun-facing side is extremely hot, indicating the planet probably does not have a substantial atmosphere to carry the sun's heat to the unlit side.

Googles driverless car


Handout photo courtesy of the Nevada Department of Motor Vehicles shows a Google self-driven car in Las Vegas, May 1, 2012. Google's self-driven cars will soon be appearing on Nevada roads after the state's Department of Motor Vehicles approved on Monday the nation's first autonomous vehicle license. The move came after officials rode along on drives on highways, in Carson City neighborhoods and along the famous Las Vegas Strip, the Nevada DMV said in a statement. The Nevada legislature last year authorized self-driven cars for the state's roads, the first such law in the United States. That law went into effect on March 1, 2012.

Toyota RAV4 EV - The only all electric SUV(cars)



Toyota Motor Sales, U.S.A., Inc. today revealed the highly anticipated all-new Toyota RAV4 EV at the 26th annual Electric Vehicle Symposium in Los Angeles. This all-electric SUV has an expected driving range rating of approximately 100 miles and charging time of approximately six hours on a 240V/40A charger. The RAV4 EV’s driving performance, dynamics and cargo capacity are equal to or exceed the gas powered RAV4 V6. Arriving fully-equipped with an MSRP of $49,800 the RAV4 EV doesn’t compromise on performance, comfort or versatility. 





“It’s all about blending the best of two worlds,” said Bob Carter, group vice president and general manager of the Toyota division. “The all-new RAV4 EV marries the efficiency of an EV with the versatility of a small SUV – in fact, it is the only all-electric SUV on the market.”

The front wheel drive RAV4 EV allows drivers to select from two distinctly different drive modes, Sport and Normal. In Sport mode, the vehicle reaches 0-60 mph in just 7.0 seconds and has a maximum speed of 100 mph. Normal mode achieves 0-60 mph in 8.6 seconds with a maximum speed of 85 mph. Maximum output from the electric powertrain is 154 HP (115kW) @ 2,800 rpm.

The dash display color illuminates red when


The RAV4 EV will go on sale in late summer 2012 through select dealers, initially in four major California metropolitan markets including Sacramento, San Francisco Bay Area, Los Angeles/Orange County and San Diego. Sales volume is planned for approximately 2,600 units over the next three years. The battery warranty is 8 years or 100,000 miles.




Hands-on: Samsung Galaxy S III review

So, the Samsung Galaxy S III (with roman numerals) is finally here, and Pocket-lint is one of the first in the world to actually get its hands on one of the Android 4.0, Ice Cream Sandwich-touting devices.

And, although we haven't had time to review it fully - including a more in-depth play with TouchWiz and the user interface other than specific new features - it's looking good. Very good indeed.

The handset itself is massive, measuring 136.6mm tall, 70.6mm wide and boasting a waistline of 8.6mm - which is basically as thin as its predecessor, the Samsung Galaxy S II, but much bigger.

It's heavier, at 133g, although that's really because of the extra glass needed to front the gorgeous 4.8-inch HD Super AMOLED touchscreen, which is eye-searingly vibrant. And that extra weight doesn't matter much in the hand, you'd barely notice (too busy looking at the tasty display).


Its resolution is HD at 1280 x 720 with a 306 PPI, so much sharper and clearer than on the previous model and, if pushed, we'd say it is better when looked at in direct comparison to an iPhone 4S Retina display, certainly with colour representation, anyway.

Our initial thoughts are that off-angle it performs better than the Samsung Galaxy Note, which can introduce a green tinge when looked at it acutely, but we'd have to spend more time with it to find out for sure. It can definitely shine brightly though, with the maximum brightness setting being dazzling.

The other thing you notice immediately is that - contrary to much of the rumoured nonsense that has littered the internet of late - there is a home button, which is solid and very tangible, and Menu/Recent Apps and Back icons either side on the fascia itself - they glow when in use, fade away when not.

On the rear there's an 8-megapixel camera and LED flash, while the front houses a 1.9-megapixel webcam that is also employed for face recognition purposes. This is one of the SGSIII's stand-out new features, which Samsung has called Smart Stay. The phone intelligently sees when you're looking at it and ensures that the screen never dims when it has eye contact.

As Min Cho, senior manager of Samsung's Korean HQ's Sales & Marketing Team, Mobile Communications, told us in an exclusive chat: "The phone only sleeps when you do.

And that's not the only interesting new control function. There's also Direct Call, which allows you to call back someone who has left a message, sent a text or communicated with you in a number of other ways by simply lifting the phone to your ear. As long as they are in your contacts list, the Galaxy S III automatically dials the number. We tried it, and it worked as easy as you like. You can also turn off the mode if you don't want to call people accidentally when moving about.
Perhaps, though, the most useful feature, and one that is probably going to be talked about more than any other, is S Voice, Samsung's equivalent of Siri that does so much more than Apple's technology.

S Voice not only allows you to control certain functions, like with former Android voice recognition technology, but it now also understands a massive gamut of natural phrases. Plus, it can be customised with up to four separate wake-up commands. For example, you can set it to respond with the phrase "Galaxy" or "get up". This will unlock the screen and get the whole shebang going. And as that specific function will  respond only to your voice, there's no concerns over security.

Samsung has also integrated voice recognition into certain embedded applications, such as the camera app. Where before you had to scrabble to find a button -either on screen or off - in order to take a shot, you can now just bark commands. "Hi Galaxy, picture," will open the camera app, for instance, then "capture" or "cheese" will take a picture. It's very effective, and a better use of vocal triggering than asking your iPhone aloud to find a nearby restaurant when on a crowded train (only to be met with "I can only look for businesses in the United States...").

You can also now control your music on the phone, even if it is playing a song loudly in the background. It's all quite similar to the way Microsoft has integrated Kinect voice recognition into its Xbox 360 UI, which we're fond of here at Pocket-lint.
The camera application has also had a few significant improvements. The Samsung Galaxy S III is capable of recording video in Full HD (1080p) - much like other Samsung top end phones - and 720p through the front-facing cam, and while you're capturing footage you can now also take stills without halting the process. Like with the normal photo modes, there's zero shutter lag too, and minimum saving time.

There's also a funky new mode called Burst Shot, which, when enabled, takes 20 photos in quick succession (at six frames per second) and automatically chooses the one it judges to offer the quality based on a number of parameters. As the phone's rear camera has multiple face recognition properties of its own, it will look to see if your subject is closing his or her eyes, whether they are smiling, etc.

Face recognition also comes into play with general shooting and the ability to zoom. Whereas you would formerly have to zoom individually on a subject using pinch on the touchscreen, now you can just double tap the box that appears around their head - the Galaxy S III immediately frames them in the picture. In addition, a new slideshow mode will zoom into faces when they appear on any of your photos, scrolling through them if there's more than one person in the shot.

And that's not all... the new software's abilities will also recognise people in the shots if they are already in you contacts list, displaying their info when hovered over and automatically sharing the picture with them through Buddy Share if you so desire.

And, if you have your contacts sorted into groups, the app will automatically detect and sort your photos into the same groups too, ensuring that your family shots are all neatly tidied into the one easy to access place. You can also tag friends and family in each photo for Facebook without having to leave the phone's camera application. Impressive stuff.
Sharing content with others has been made much easier too, especially if they also have a Samsung Galaxy S III. The new device is NFC-enabled and comes with Wi-Fi Direct in-built, so Samsung has combined both Android Beam and Wi-Fi Direct into one technology it calls S Beam. This allows you to simply touch two handsets together in order to transfer picture or video files regardless of their size.

It works a treat, based on our hands-on test, with transfer speeds of up to 400Mbps (via NFC). Presumably, the Wi-Fi Direct option (offering up to 300Mbps speeds) has been added so that it could potentially communicate with non-NFC devices. Time will tell.

Other wireless highlights are supplied by the now Samsung standard DLNA-enabled AllShare Play, which allows you to access files on the phone through a laptop, Smart TV, etc, and new feature AllShare Cast which allows you to transmit HD content on to a compatible TV, effectively mirroring the entire display. It's great for playing games on a much bigger screen.

The phone is HSPA+ for the UK but will be LTE (4G) in other supported countries. It's a shame we don't have the networks sorted out over here in time, but it's hardly an issue considering its peers are similarly hamstrung.

One last new feature we instantly fell in love with is a by-product of the Galaxy S III rocking Samsung's new 1.4GHz Exynos 4 Quad processor and a healthy 1GB of RAM; pop up video. When watching video - HD or otherwise - you can still multitask, use the internet, send a text message and whathaveyou, and the clip will continue to play in a small pop-up window. And the best part is that you can swipe it around the screen, allowing you to access whatever you need underneath.
We tried it out with the internet and, specifically, searching for something on Google, and the clip ran as smoothly as if we hadn't touched it at all. Of course, it's in a much smaller form factor, but as soon as you go back to it, it expands to fill the screen again. Brilliant.

There'll be other surprises in the speed stakes to be had too, once we've played with the phone a bit more, after all the graphics processing is also quad core, with an increased clock speed of 65 per cent over the Samsung Galaxy S II. It'll certainly be interesting to see what Android developers can do with such extra power.

We suspect that power doesn't come at the cost of battery life either, with a 2100mAh cell on board, although from our play, we can't confirm that yet. The team behind the Exynos 4 Quad chip do claim that the processor itself has 20 per cent drain on the battery, but there's the bigger screen to take into acount, OLED or no.
On launch, the new smartphone will come with several pre-installed apps, including those detailed above. All of Samsung's usual hubs will be present and also Flipboard (with which you can get daily Pocket-lint news) and Dropbox. The latter will come as a brief shock to those who believed the rumours that Samsung was launching its own cloud service alongside the Galaxy S III, but its full integration here is much welcome, as is the 50GB of free storage space - wowsers!

So too, bizarre it may seem to some, is Samsung's decision to adopt micro SIM for its flagship phone. As we handle a fair few smartphones in Pocket-lint towers, all our SIMs are micro or cut-down, and some of the devices we get through our doors aren't as receptive to plastic SIM size-converters as you'd hope. But we can understand that others might not be so pleased with the news, especially those who hot swap devices.

At least it matches the microSD and MHL video output in minimising socketry. The former behaves as with plenty of Samsung phones before it, allowing you to expand the 16GB, 32GB or 64GB built-in memory (depending on which version you opt for) by up to 32GB, whereas the latter offers connectivity between the device and a HD TV.

Finally, this hands-on review would not be complete without talking about the feel of the phone in the hand and the overall aesthetics.
Coming in Pebble Blue and Marble White (we much prefer the white version), both flavours of the Samsung Galaxy S III have been designed with nature in mind. Indeed, Cho told us that the philosophy behind the phone is, "inspired by nature, designed for humans," which also runs through the choice of wallpapers and a water rippling effect (visually and aurally) on the unlock screen.

The rear is smooth and rounded, while the front, to be honest, looks like the Galaxy Nexus, if just a little larger. As previously mentioned, it's extremely light, but as the bezel is one of the thinnest Samsung has ever managed, the screen feels even bigger than its 4.8-inches.

If there's anything we were slightly down on it's that the back panel feels a little plasticky, especially when compared to other brands' flagship phones, such as the Panasonic Eluga dL1 or Nokia Lumia 900, but at least it keeps the weight down. This is not a handset to stroke longingly, this is a handset to use.

And, that's the point. Although it's early doors in our testing process, Samsung has created a powerhouse of a smartphone, one that can truly make claims to being a portable computer in your pocket. We've seen enough to know that iPhone 4S fans will be sick with envy.
