Why we have to turn electronic devices off on planes

Are phones safe to use on planes?

 A recent survey found around four out of 10 US air passengers admitted they don’t always turn their gadgets off on flights. One notable occasion saw the actor Alec Baldwin reacting furiously on Twitter after being kicked off a Los Angeles-to-New York flight before take off for refusing to stop playing the online game Words With Friends on his phone.

According to regulations, which are pretty uniform around the world, the use of portable electronic devices is not allowed below around 3,000m (10,000ft), even in "flight mode” which stops the transmission of signals. Above this height devices like laptops and music players can be used, but phones must remain off. These rules are important, we are told, to avoid potentially dangerous interference between signals from these devices and sensitive onboard electronic systems. But do these fears have any scientific basis, or is it time to relax the rules?

The fear of interference comes from the fact that gadgets connect to the internet or to mobile phone networks using radio waves. To explain the theoretical dangers, Peter Ladkin, Professor of Computer Networks and Distributed Systems at Bielefeld University, Germany, uses the analogy of holding a blowtorch to your household heating pipes. The central heating system in your house makes changes based on the readings of thermometers within those pipes, so the blowtorch will heat the water, change the temperature readings and trigger the system to make adjustments.

Personal mobile devices could act in a similar way on aeroplanes, on which hundreds of electronics-based systems, known as avionics, are used for navigation, to communicate with the ground and to keep track of the components that keep them in the air. Some involve sensors that communicate information to cockpit instruments. It's not just an issue with mobile phones. Kindles, iPods, laptops, handheld gaming consoles – they all emit radio waves. If these are at frequencies close to those of the avionics, signals and readings could be corrupted. This could affect systems such as radar, communications and collision avoidance technology, and the problem is potentially magnified if gadgets are damaged and start emitting stronger radio waves than they should, or if signals from multiple devices combine.

So much for the theory, but is there any proof that this is a problem? There are no known recorded incidents of crashes having been definitely caused by such interference, but that said the causes of accidents can sometimes remain unknown. A flight recorder may not identify that a critical system has failed because of electromagnetic interference from passengers’ devices.

System malfunction

But while definite proof may be lacking, there is plenty of anecdotal evidence that the risks should be taken seriously. A report summarising 50 cases of safety issues thought to have been caused by personal electronic devices, was published in January this year. These were compiled from the US Aviation Safety Reporting System, a database maintained by Nasa, to which crew members can anonymously submit reports of safety problems. One such case was summarised as follows: "First Officer reports compass system malfunctions during initial climb. When passengers are asked to verify that all electronic devices are turned off the compass system returns to normal.”

A 2006 analysis of the database identified 125 reports of interference from electronic gadgets, of which 77 were defined as "highly correlated". In one incident a 30-degree error in navigation equipment was immediately corrected when a passenger turned off a portable DVD player. This problem reoccurred when the device was switched back on. Fight crew have reported a number of similar cases in which they have watched readings on navigations systems change apparently in response to passengers being asked to turn specific devices on and off. In another report, the International Air Transport Association (IATA) identified 75 separate incidents of possible electronic interference that pilots believe were linked to mobile phones and other electronic devices between 2003 and 2009.

In the competitive world of aviation, some airlines such as Virgin Atlantic and Delta Airlines have started advertising the use of technologies that allow greater use of mobile devices on flights. In-flight mobile phone systems such as OnAir and AeroMobile use miniature on-board base stations called picocells which allow devices to transmit at lower power levels. Transmissions are processed, transmitted to a satellite and then on to the normal ground networks. This, says AeroMobile chief executive Kevin Rogers, enables the use of mobiles “as a roaming service just like when you go to a foreign country, except that in a foreign country you don’t need a satellite link.” Some airlines are now starting to fit AeroMobile equipment during production.

These systems allow you to use your phone while at cruise altitude, but not during take-off and landing. Rogers thinks that this might change one day, but at the moment it is still difficult to “prove categorically that there is indeed no interference – so airlines tend to err on the side of caution and be conservative.”

But as Rogers adds: “Many phones are always left on anyway. If there was a real risk of interference of a mobile phone or an iPad with the aircraft’s systems, people would not be allowed to take them on the aircraft at all.”

Some air authorities remain unconvinced, however. In-air mobile services cannot be used in US airspace, for example. The US Federal Aviation Administration has come under pressure to relax its rules and last year set up a group of experts to study the question. A decision is expected by the end of this year.

Richard Taylor, a spokesman of the UK’s Civil Aviation Authority, believes it is just a matter of time before we see more widespread use of mobile devices on aircraft, but that calls will remain banned during take-off or landing for the foreseeable future.

“When regulators like us are convinced that an aircraft can be used safely even with portable electronic devices being used in the cabin, that the signal being emitted from the cabin at any stage of the flight can be safely absorbed without affecting any of the aircraft systems, of course the rules will be relaxed,” he says. “But it’s up to the manufacturers, and of course to the airlines, to prove that they are operating the aircraft safely.”

Perhaps that day may come soon. However, having learnt how difficult it is to prove definitively that planes are safe from interference, I'll be making sure my phone is properly switched off in future. After all, when I'm en route to my holiday in the sun, I don't want my handset to be responsible for tricking the pilot into landing in some rainy old place. Or for something even worse.

Is it a iphone or bowling ball?

Why would you want to turn your precious, state-of-the-art and epitome of sophistication iPhone into a bright-yellow foam ball? Well perhaps if you’re into iPhone gaming, as this decidedly un-tech looking gadget has the potential to take iPhone gaming to another level.

Created by Physical App, LLC, TheO has a cut out slot where you place your iPhone or iPod touch and then hurl the ball across the floor as part of the game. Thanks to the iPhone’s accelerometer, TheO combines the physical activity and iPhone gaming into one.
Physical Apps currently has three free TheO games, a bowling app, Hot Potato and a social game, Interrogo.
It might not look like the height of tech-sophistication but TheO certainly ranks in the novel stakes and is expected to debut in May!

Ubuntu for android

Today in the world of computer operating system we found many OS such as windows,ubuntu(linux-open source) etc.What is more important to us is the integration of the os with the mobile phones or tab but as we know android ,ios,windows, already covered the mobile OS market in the world. So planning to launch a new os is wastefull idea looking at ths scenario ubuntu developers came up with a brilliant idea of integrating ubuntu with the android os.

Xbox One costs more to make than the PS4 : Thanks to ESRAM and Kinect

Xbox One, in pieces [Image credit: iFixit]

If you bought an Xbox One for $500, rest assured that you got a good deal: It cost Microsoft $471 to make the Xbox One, new Kinect, and everything else in the box. After the retailers’ cut, Microsoft loses money on every Xbox One sold. At $471, the Xbox One costs about $90 more than the PS4 — a cost difference that is almost entirely down to the new Kinect, which costs around $75 to make.
This data comes from IHS iSuppli, which reported its bill-of-materials teardown analysis of the PS4 last week, and then the Xbox One today. The cost of making an Xbox One mostly boils down to the APU ($110 from AMD), 8GB of RAM ($60 from SK Hynix), and the Kinect ($75). The cost of the console itself comes to around $332, with the Kinect, power brick ($25), gamepad ($15), and headset making up the remainder.

Nanoparticle-infused speaker could mean better sound in a smaller package

Nanoparticle speaker: Check out how thin it is!Nanotechnology has contributed to all sorts of important medical and scientific breakthroughs, but when is it going to make speakers sound better? It’s a question we all ask ourselves every hour of every day, of course, but your nanotech speakers are almost ready. A team of researchers from Sweden’s KTH Royal Institute of Technology have created a new kind of loudspeaker that relies on nanoparticle-infused membranes to generate sound without need of a permanent magnet.
The main constituent of the membrane is cellulose fiber — the polysaccharide component of plant cell walls. Researchers mixed the cellulose fibers in solution with ferromagnetic salts at 90 degree Celsius, then left the mixture to bond over the course of two months. The remaining water was drained at the end of this period to reveal a hydrogel (a hydrophilic collection of polymers) composed of magnetic cellulose fibers.

How the nanoparticle speaker was made, from log, to a rather nasty-looking pile of hydrogel

HBO Go comes to Chromecast on both Android and iOS

HBO Go comes to Chromecast
See, when the Chromecast first launched, it was intriguing primarily because of its exceptionally low price point. People who ran out and bought one  were investing in promised future functionality, not its current feature set. Well, it's safe to say that money was not wasted. With today's announcement that HBO Go will now support Chromecast, Google has brought most of the major non-sports streaming properties to its tiny dongle, including Netflix and Hulu. It's particularly impressive given how notoriously slow HBO has been to bring its streaming service to "new" platforms. Now Google-loving nerds across the US will be able to get their "Game of Thrones" fix on demand on their TV simply by tapping an icon on their Android or iOS tablet. Of course, that is if you're an HBO subscriber. The update is already hitting both the iTunes App Store and Google Play, so go download it now.

For true panoramic images, toss this camera in the air. Seriously

Making a panoramic image by taking one photo after another is so 2013.
On Tuesday, Panono, a startup based in Berlin, launched an Indiegogo campaign to raise money to develop its throwable camera, a small, ball-shaped device built with 36 integrated lenses that is designed to capture a high-quality 360x360-degree image all at once.
The idea is simple: A user tosses a Panono in the air, and just at the moment it reaches its peak height, all 36 lenses fire simultaneously. Immediately, a low-res version of the image is viewable on a smartphone app, and within a couple of minutes, the full 72-megapixel image is available.

According to Panono co-founder Jonas Pfeil, the camera is ideal for taking shots in dynamic situations. Family outings at the beach are an example, he said. But he also showed that the camera is perfect for capturing the broad vista high above Hong Kong, or the chaos in Tokyo's famous Shibuya crossing.
Panoramas taken with the Panono can be viewed in a number of ways. The best may well be on a tablet, which allows the user to move around the photo simply by tilting the device. But the images can also be embedded into any Web site, where they appear somewhat like a Google Street View scene.
When the Panono goes on sale, likely next September, it will cost $600, Pfeil said. But those who support it through Indiegogo will pay $550. In the coming months, the company will be working hard to produce the cameras, making sure that it is able to make enough of them to meet demand, and that each is made with the durable polycarbonate material that allows users to throw them up to about 9 feet in the air with confidence that they can survive hitting the ground.
To be sure, $600 -- or even $550 -- is a lot to spend on a camera with limited utility. But Pfeil believes that anyone who travels a lot, or who spends time playing in parks, or who, say, has kids, will relish the ability to quickly and easily take full panoramic photographs, and then just as easily share them.
It's too early to tell, of course, if the market will agree. But within the last few days, another company has emerged with a ball-shaped 360-degree camera. Panono thinks its offering is far more sophisticated, however, given that its device shoots much higher-resolution images and can be thrown in the air.

Of course, the Panono also can be mounted on a stick or held in a user's hands. But there's little doubt that most people will come to know of the Panono because it is throwable.
Could this be too gimmicky to succeed? Absolutely. But there's little doubt that there is widespread interest in panoramic photography. Apple, for example, built a panorama tool into the iPhone's camera, and there is plenty of software designed to auto-stitch multiple photos into a single panorama. Panono is hoping that photographers will opt for the ease of tossing a small ball in the air once and having all the work done for them.

Nintendo Wii U

Every game console including the Nintendo Wii has a selection of online video services like Netflix and Hulu Plus, but the Wii U goes a step further.  Nintendo TVii aggregates your favorite shows and movies across multiple services and lets you decide how you want to watch content on Netflix, Hulu Plus, or even your TiVo DVR or cable box. Sports games and other shows get additional information integration, with live scores of multiple games at once appearing on the gamepad while you watch. You can have multiple favorites lists based on different members of your household, and users can respond to content in realtime and share their thoughts with other users.

Meet the Hal 9000 of doorbells. (Hopefully this one won't lock you out.)

It’s a common struggle for urban internet shoppers: You order plenty of great stuff online, but you’re at work during the day, and your apartment doesn’t have a safe place for package deliveries. Doorbot, a new camera/doorbell/HAL 9000 lookalike, will notify your smartphone when your doorbell rings — even if you’re miles away — so you can let the UPS guy inside or simply give him permission to leave your package on your step.
The home-automation device, which is currently available for pre-order at Amazon, combines video surveillance with a doorbell. It’s like a video intercom, except instead of video being beamed to a fixed screen, it can go straight to your smartphone. In order to do this, the Doorbot has many of the same components as an embedded system. It connects to your home Wi-Fi, it runs off a rechargeable lithium-ion battery (with an estimated battery life of just under a year), and it includes a fisheye camera. One particularly cool feature is night-vision mode, which lets you see who’s at your door even if you don’t have a brightly-lit stoop. When someone rings Doorbot, you’ll get a push notification on your phone, and you can see who rang and even communicate with them with an intercom-like feature. If you pair Doorbot with a Lockitron lock, you can also unlock the door for guests remotely — which would be perfect for running an Airbnb or loaning out an extra room to friends.
The Doorbot comes with a theft-resistant mount and looks fairly easy to install. During the process, you can choose to wire it so it draws power like a conventional doorbell — you know, if you’re nervous about disconnecting it every year to recharge. On the other hand, if you don’t fully mount and wire it, Doorbot can detach and be used as a wireless video camera away from the doorjamb.
A few Doorbots started shipping as rewards for a successful crowdfunding campaign, but the first commercial shipment won’t be available on Amazon until December 1. You can pick one up for $200. There’s a package with an included Lockitron for an extra $150, too.

Smart gun technologies making weapons more accurate - and more deadly

The marriage of technology and weaponry is creating a growing but expensive class of “smart” guns that promises to boost security, improve accuracy -- and make guns even deadlier. But even gun-rights advocates aren't sure that's such a good thing.
"Are there any legitimate gun owners who are calling for this technology for safety? I haven't heard of one," said Jim Wallace, exectuvie director of the Massachusetts Gun Owners Action League, in a recent interview.
One example is a newly unveiled “super gun” from Tracking Point that emulates the target-locking technology from jets to turn any rifle into an ultra-accurate sniper gun capable of consistently hitting a target from 1.75 miles away.

PS4 vs. Xbox One

PS4 system board, and other hardware bits

For the first time in the history of video game consoles, it’s actually possible to do an almost direct comparison of the hardware inside the PS4 and Xbox One. In almost every one of the seven preceding generations, game consoles were outfitted with highly customized chips and CPUs featuring niche, specialized architectures that could only really be compared very generally (bits, flops) or in the very specific (number of on-screen sprites, MIDI instruments, etc.) The PS4 and Xbox One, however, are very similar consoles. With an x86 AMD APU at the heart of each, the Sony and Microsoft consoles are essentially PCs — and their hardware specs, and thus relative performance, can be compared in the same way that you would compare two x86 laptops or ARM Android tablets.

First ever metal 3D printed gun manufactured in the US

The gun has fired over 600 rounds in testing and 'functions beautifully'

A fully-functioning metal gun has been 3D printed for the first time ever by a firm in the US.

There has been a great deal of discussion and controversy surrounding the 3D printing of guns and now, a metal M1911 pistol has been printed in 3D by Solid Concepts in Austin, Texas, using direct metal laser sintering (DMLS) technology.
DMLS, an additive manufacturing technology, works by taking 3D computer-aided design (CAD) data and slicing it up into numerous 2D components. Each component acts as a blueprint for the 3D printer, telling the machine where to sinter the metal material. Every component is sintered, building the gun up layer by layer. For the gun in question, each part was printed using DMLS technology except for six springs.
A video (below) has been released by Solid Concepts which shows the gun being put through initial tests. The firm are now claiming that over 600 rounds have been fired by the pistol and that it “functions beautifully”.
So is a 3D printed metal gun cause for concern? For now, at least, it doesn’t appear so. The 3D printers that are available to the general public are far from capable of printing in metal. According to Solid Concepts, the printers required to carry out such an action can cost in excess of one million dollars. Furthermore, a federal firearms licence (which Solid Concepts has) is needed to manufacture the gun.
And even though the firm has cracked the production of the gun, it currently doesn’t have any plans to sell it. Writing on the official blog, however, Solid Concepts has said that it is “weighing its options for the future” and that any commercially available gun would retail “in the five-figures”.
Keen to clarify the firm’s motives for 3D printing the metal gun, Phillip Conner, the DMLS manager at Solid Concepts said: “When we decided to go ahead and make this gun, we weren’t trying to figure out a cheaper, easier, better way to make a gun – that wasn’t the point at all. What we were trying to do was dispel the commonly held notion that DMLS parts are not strong enough or accurate enough for real-world applications.”

New 'active' invisibility cloak design 'drastically reduces' visibility

Research from the US shows the limitations of current 'passive' designs and points the way towards new, 'actively' powered metamaterials

Bose QuietComfort 20

Bose’s first in-ear headphones to offer noise-cancelling tech use dual mics in each lug to detect and counter outside sounds, insulating you in a cocoon of your own tunes. However, press a button on the slightly bulky control unit and said mics can also allow you to hear what’s going on around you, via the miracle of “Aware mode”. This lets mid to high frequencies through so you can hear station announcements and the like. The battery provides up to 16 hours of noise cancellation on a single charge, with a full rejuicing via USB taking two hours.

Future robots powered by pee

Future robots powered by pee? Urine luck! Future robots powered by pee? Urine luck!

There's that old saying that goes, "It's better to be pissed off than pissed on." That is, unless you're a robot.
Researchers from the UK have created a device that works like an artificial heart to pump urine into a microbial fuel cell that would power robots, making it possible for them to turn the waste into electricity.
"In the future, we hope the robots might be used in city environments for remote sensing," where they could help to monitor pollution, temperature, humidity, and waste water quality, said Peter Walters, an industrial designer at the University of the West of England and lead author of the study that appears in the journal Bio inspiration and Biometrics.
"In the city environment, they could recharge using urine from urinals in public lavatories," Walters added. "In rural environments, liquid waste effluent could be collected from farms

Google Chromecast

Google has announced a brand new streaming accessory — the Chromecast — that makes it easy to bring web content to the TV.
At first blush, the Chromecast looks like the spiritual successor to the ill-fated Nexus Q. The Chromecast is an HDMI dongle that communicates with video and audio apps — including YouTube, Netflix and Pandora — running on Android or iOS, and transfers that content to your big screen HDTV.
GooglechromecastUsers can then control content on the big screen using apps on their phones or tablets. Users can also "cast" content from the Chrome browser to the Chromecast. There's also beta support for bringing any Chrome tab to the Chromecast.
Right now, the Chromecast will support:
  • YouTube
  • Netflix
  • Google Play
  • Google Music
  • Chrome for Windows, Mac and Chroembook Pixel
The implementation seems extremely similar to what Apple offers with AirPlay and the Apple TV. Like Chromecast, AirPlay apps let users stream content — often at a higher resolution — directly to the Apple TV, while still maintaining the ability to do other things on the phone or tablet and also offering control for the playback via a Mac, iPhone, iPad or iPod touch. OS X Mountain Lion offers AirPlay mirroring and the upcoming version of OS X Mavericks users AirPlay to create a second or third monitor for users.
The biggest difference with Chromecast is that it is cross-platform. Google is also launching a new Google Cast SDK to make it easy for iOS, Android and Chrome devs to add Chrome Cast support to their existing apps.
"Our goal is to partner to create an ecosystem of apps as well as devices," Google said. "While the Chromecast device is the first instantiation of Google Cast, we expect the technology to be embedded in a range of devices from our partners."
Chromecast will sell for $35 at Amazon, Best Buy and the Google Play store and will include three free months of Netflix for a limited time.

Google Glasses accessory store

Shortly after announcing a hardware upgrade for Google Glass owners, Google has launched an accessory store for the head-worn gadget.
Accessible only to Glass Explorers such as Nick Starr — early buyers of Google Glass — the store carries an extra cable and charger, a microfiber pouch, a new Clear Shield (compatible with the latest variant of Glass) and an extra Mono Earbud, which also comes with the new version of Glass.

The prices are hefty: $50 for the charger, $50 for the microfiber pouch, $75 for the Clear Shield, $50 for the Mono Earbud. Glass is not ready for the market yet, but we're betting these prices will go down once it becomes available to everyone.
Currently, all items are listed as out of stock except for the Clear Shield.
