#Laser-Radio links Upgrade the Internet The rise of Wi-fi and cellular data services made Internet access more convenient and ubiquitous.
Now some of the high-speed backhaul data that powers Internet services looks set to go wireless, too.
in wireless hops of up to 10 kilometers at a time, is in trials with three of the largest U s. Internet carriers.
It is also being rolled out by one telecommunications provider in Mexico, and is helping build out the Internet infrastructure of Nigeria,
a country that was connected to a new high-capacity submarine cable from Europe last year. AOPTIX, the company behind the technology, pitches it as a cheaper and more practical alternative to laying new fiber optic cables.
Efforts to dig trenches to install fiber in urban areas face significant bureaucratic and physical challenges.
says Chandra Pusarla, senior vice president of products and technology at AOPTIX. He says a faster way to install new capacity is to use his company wireless transmission towers to move data at two gigabits per second.
AOPTIX technology takes the form of a box roughly the size of a coffee table with an infrared laser peering out of a small window on the front,
AOPTIX teamed up the laser and radio links to compensate for weaknesses with either technology used alone.
while millimeter wave radio signals are absorbed by rain. Routing data over both simultaneously provides redundancy that allows an AOPTIX link to guarantee a rate of two gigabits per second with only five minutes or less downtime in a year,
whatever the weather conditions, says Pusarla. A typical fiber connection might be 10 or more times faster than that, due to the limitations of the radio frequency link.
But AOPTIX says the convenience of its technology makes up for that and it could be increased to four gigabits or more in the future.
The radio and laser equipment inside an AOPTIX device move automatically to compensate for the swaying of a cell tower caused by wind.
AOPTIX originally developed its laser technology for the Pentagon, designing systems that actively steer laser beams to keep data moving between ground stations, drones, and fighter jets.
Pursala declined to identify the three U s. carriers that have been testing AOPTIX technology over the past year or so,
or its Nigerian customer. Other early customers are being more open. The Mexican telecommunications company Car-sa recently switched on the first of several links it plans to use to link up cellular towers
and provide Internet to corporate customers. And before the end of the year, Anova Technologies, a networking company that specializes in the financial industry,
will use AOPTIX technology in New jersey to shave nanoseconds off the time it takes data to travel between the computers of Nasdaq Stock market and the New york stock exchange e

and a conventional printer and scanner. Youe encouraged to hook it up to a 3-D printer,
like the one HP launched alongside the Sprout. All that is supposed to make Sprout into a powerful new tool for designers and other creatives.
You might use the device to scan, say, a Buddha statuette in 3-D, and then use a stylus to modify the digital scan once it is projected onto the workstation touch-sensitive surface.
After you made your change, you could print the new design out in 3-D. Sprout shows signs of HP history of making PCS and printers,
with matte grey casing and the bulbous contours of a Ford taurus. But it is clearly the product of some very clever engineering and an ambitious product strategy.
While computer processers and memory have advanced over the decades, we have continued to interface with them via monitor, keyboard, and mouse.
More recently, tools for making things in the physical world have changed a lot too, with the advent of maker spaces and affordable, computer-controlled lathes, mills,
and 3-D printers. But in neither of these cases do you have the opportunity to take control of the world of physical outputs
and software-based design and computing together. Sprout is a clunky device to gaze upon,
but it dreaming in a big way about the very nature of work. You can do things with Sprout that had previously only had been possible by piecing together at least a half dozen different devices.

#Google's Secretive Deepmind Startup Unveils a Neural Turing Machine""One of the great challenges of neuroscience is to understand the short-term working memory in the human brain.
At the same time computer scientists would dearly love to reproduce the same kind of memory in silico. Today Google s secretive Deepmind startup which it bought for $400 million earlier this year unveils a prototype computer that attempts to mimic some of the properties of the human brain s short-term working memory.
The new computer is a type of neural network that has been adapted to work with an external memory.
The result is a computer that learns as it stores memories and can later retrieve them to perform logical tasks beyond those it has been trained to do.
Deepmind s breakthrough follows a long history of work on short-term memory. In the 1950s the American cognitive psychologist George Miller carried out one of the more famous experiments in the history of brain science.
During the 1990s and 2000s computer scientists repeatedly attempted to design algorithms circuits and neural networks that could perform this trick.
Such a computer should be able to parse a simple sentence like Mary spoke to John by dividing it into its component parts of actor action and the receiver of the action.
So in this case it would assign the role of actor to Mary the role of action to the words spoke to
They begin by redefining the nature of a neural network. Until now neural networks have been interconnected patterns of neurons
But the fundamental process of computing contains an important additional element. This is an external memory
and read from during the course of a computation. In Turing s famous description of a computer the memory is the tickertape that passes back and forth through the computer and which stores symbols of various kinds for later processing.
This kind of readable and writable memory is absent in a conventional neural network . So Graves and co have added simply one.
This allows the neural network to store variables in its memory and come back to them later to use in a calculation.
This is similar to the way an ordinary computer might put the number 3 and the number 4 inside registers and later add them to make 7. The difference is that the neural network might store more complex patterns of variables representing for example the word Mary
. Since this form of computing differs in an important way from a conventional neural network Graves
and co give it a new name they call it a Neural Turing Machine the first of its kind to have been built.
The Neural Turing Machine learns like a conventional neural network using the inputs it receives from the external world
but it also learns how to store this information and when to retrieve it. The Deepmind work involves first constructing the device
They compare the performance of their Neural Turing Machine with a conventional neural network. The difference is significant.
The conventional neural network learns to copy sequences up to length 20 almost perfectly. But when it comes to sequences that are longer than the training data errors immediately become significant.
Once again the Neural Turing Machine significantly outperforms a conventional neural network. That is an impressive piece of work. Our experiments demonstrate that our Neural Turing Machine is capable of learning simple algorithms from example data
and of using these algorithms to generalize well outside its training regime say Graves and co. That is an important step forward that has the potential to make computing machines much more brainlike than ever before.
But there is significant work ahead. In particular the human brain performs a clever trick to make sense of complex arguments.
An interesting question that follows from Miller s early work is this: if our working memory is only capable of handling seven chunks how do we make sense of complex arguments in books for example that consists of thousands or tens of thousands of chunks?
To Miller the brain s ability to recode in this way was one of the keys to artificial intelligence.
He believed that until a computer could reproduce this ability it could never match the performance of the human brain.
Google s Deepmind has stated that its goal is solving intelligence. If this solution is anything like human intelligence a good test would be to see
#A Credit card Terminal That Takes Apps Last year Osama Bedier then the head of Google Wallet decided he was on the wrong side of the payments business.
The sleek-looking $299 touch-screen gadget accepts cards with embedded chips which will soon be widespread as well as digital payments
Google s digital payment app Google Wallet offers consumers a number of payment-related features including a quick way to pay at stores by tapping a phone that contains a near-field
Although adoption of Google Wallet has been slow NFC technology is gaining in popularity and that is likely to accelerate with the introduction of a similar system from Apple called Apple Pay (see With Apple Pay Forget Cash Just Pull out Your Phone).
Meanwhile the U s s major credit-card companies are mandating a shift to more secure credit cards that eschew the familiar magnetic strip for a chip that uses a unique string of numbers for each transaction (a standard known as EMV
Bedier a former Paypal executive who came to Google in 2011 saw an opportunity to switch his focus from the gadgets we can use to make payments to the ones used to handle the transactions:
Poynt s terminal is dominated by two touch screens that meet at an angle a seven-inch display that a store employee will use to ring up sales
and there s a built-in receipt printer that will spit out paper from an opening below the customer touch screen.
It accepts payments via NFC (used by services such as Google Wallet and Apple s new Apple Pay) and QR code.
It includes Bluetooth as well. Bedier showed me how it works during an interview conducted via Skype video.
The Poynt terminal he used said Welcome to Main St. Bakery on the customer screen
Merchants could use the screen for ads or store specials when not taking payments Bedier says.
and make a purchase using Apple Pay on an iphone: Bedier typed in the amount due
and the colleague tapped the terminal with his iphone while placing his finger on the iphone s home button
which on newer models is also a fingerprint reader to validate his identity. The Poynt terminal weighs a little over a pound
and contains a wireless modem and eight-hour rechargeable battery which means it could be carried around a store or restaurant if needed.

#How Magic Leap s Augmented reality Works A Florida startup called Magic Leap announced Tuesday that it had received $542 million in funding from major Silicon valley investors led by Google to develop hardware
for a new kind of augmented reality hardware. The secretive startup has yet to publicly describe or demonstrate its technology,
what the company CEO and founder Rony Abovitz has called he most natural and human-friendly wearable computing interface in the world.
The filings describe sophisticated display technology that can trick the human visual system better than existing virtual reality displays (such as the Oculus Rift) into perceiving virtual objects as real.
The display technology used in most devices can show only flat, 2-D images. Headsets like the Oculus Rift trick your brain into perceiving depth by showing different images to each eye,
but your eyes are focused always on the flat screen right in front of them. When you look at a real 3-D scene,
the depth at which your eyes are focused changes as you look at objects at different distances away. f we leave out those focus cues we get an experience that not quite realistic,
They describe displays that can create the same kind of 3-D patterns of light rays, known as ight fields,
Earlier this year, Wetzstein and colleagues used that technique to create a display that allows text to be read clearly by people not wearing their usual corrective lenses (see rototype Display Lets You Say Goodbye to Reading Glasses.
He previously worked on glasses-free 3-D displays based on similar methods. And last year, researchers at chip company Nvidia demonstrated a basic wearable display based on light fields.
A trademark filing from July describes Magic Leap technology as earable computer hardware, namely, an optical display system incorporating a dynamic light-field display.
One of Magic Leap patents describes how such a device, dubbed a WRAP, for aveguide reflector array projector, would operate.
The display would be made up of an array of many small curved mirrors; light would be delivered to that array via optical fiber,
and each of the tiny elements would reflect some of that light to create the light field for a particular point in 3-D space.
Multiple layers of such tiny mirrors would allow the display to produce the illusion of virtual objects at different distances.
That would allow the mirrors to be reprogrammed using a magnetic field to rapidly display points at different depths fast enough to fool the eye
Magic Leap greatest challenge may be to find a way to seamlessly integrate virtual 3-D objects created by that display with
and eye-tracking cameras on a wearable display to figure out at what depth a person eyes are focused.
Depth-sensing cameras are now relatively cheap and compact (see ntel Says Tablets and Laptops with 3-D Vision Are Coming Soon.
But Wetzstein says Magic Leap will need likely to make major breakthroughs in computer vision software for a wearable device to make sense of the world enough for very rich augmented reality. hey will require very powerful 3-D image recognition,
running on your head-mounted display, he says. The company is recruiting experts in chip design and fabrication
apparently with a view to creating custom chips to process image data. Dedicated chips could make that work more energy-efficient, something important for a wearable device.
Magic Leap already employs Gary Bradski, a pioneer of computer vision research and software, notes Wetzstein.
manufacturing supply-chain management, 3-D sensing, artificial intelligence, and video game development. Altogether, many of the underlying techniques Magic Leap needs to realize highly realistic augmented reality have been demonstrated,
says Wetzstein. But the company will have to refine and combine them in ways no one has managed yet to do. think people are starting to realize this is the future of building consumer devices he says. ut it involves big challenges at the intersection of optics, electronics, algorithms,
and understanding the human visual system. h

#Apple's Quiet Attempt to Shake up Wireless Carriers Could Benefit Us All If you happened to pore over the details added to Apple website yesterday about its new ipads,
you might have noticed that models with cellular capabilities include something interesting on the wireless front.
They use a special SIM CARD-the tiny card that allows your device to connect to a carrier network-called Apple SIM.
You will be able to use a setting in ios to quickly switch from carrier to carrier right on the ipad
To start, you will be able to choose from AT&T, T-Mobile, and Sprint in the U s,
the Apple SIM is added eventually to the iphone (and, perhaps, similarly flexible SIMS appear for other smartphones as well).
Not only would it make it easier to move from one carrier to another, but it could also make it more affordable for people all over the world to communicate.
I asked Apple why the company didn mention the feature during its ipad news event Thursday in Cupertino.
For now, it more of an intriguing footnote to Apple refresh of its ipad line
which account for much of its iphone sales and subsidize their cost to consumers. That said, Apple does have a lot of influence over wireless carriers.
It even convinced Cingular Wireless (which then became a part of AT&T) to agree to sell the first iphone without even setting eyes on the device.
