Apple submits patent application for magnetic and sound-based peer-to-peer technology
A patent discovered by Patently Apple suggests that Apple may use a magnetic compass and supersonic tone technology to share data between your iPhone and other electronic devices. In this new peer-to-per communication system, a magnetic compass is used to monitor the magnetic signature of a compatible electronic device. Once these devices are close together, they could automatically recognize one another and share information seamlessly without user intervention. In another scenario, a device with a speaker could output an encoded supersonic tone that changes the local magnetic field. This change in the magnetic field can be detected by the receiving device. The supersonic tone is not audible to human ears, but it may drive your dog bonkers. Once the tone is detected by the compass on the portable device, the two devices will open a connection and share contact information, images, media and other files. Similar to a MAC address for a Wi-Fi-enabled device, these signatures may be unique to each device. Once detected, the signatures could be stored and recognized for later use.
First light wave quantum teleportation achieved, opens door to ultra fast data transmission
Mark this day, folks, because the brainiacs have finally made a breakthrough in quantum teleportation: a team of scientists from Australia and Japan have successfully transferred a complex set of quantum data in light form. You see, previously researchers had struggled with slow performance or loss of information, but with full transmission integrity achieved -- as in blocks of qubits being destroyed in one place but instantaneously resurrected in another, without affecting their superpositions -- we're now one huge step closer to secure, high-speed quantum communication. Needless to say, this will also be a big boost for the development of powerful quantum computing, and combine that with a more bedroom friendly version of the above teleporter, we'll eventually have ourselves the best LAN party ever.
Kinect used to make teleconferencing actually kind of cool (video)
No matter how hard Skype and others try to convince us otherwise, we still do most of our web communications via text or, if entirely unavoidable, by voice. Maybe we're luddites or maybe video calling has yet to prove its value. Hoping to reverse such archaic views, researchers at the MIT Media Lab have harnessed a Kinect's powers of depth and human perception to provide some newfangled videoconferencing functionality. First up, you can blur out everything on screen but the speaker to keep focus where it needs to be. Then, if you want to get fancier, you can freeze a frame of yourself in the still-moving video feed for when you need to do something off-camera, and to finish things off, you can even drop some 3D-aware augmented reality on your viewers. It's all a little unrefined at the moment, but the ideas are there and well worth seeing. Jump past the break to do just that.
First 'Skype booth' opens at Estonian airport as company reaches 30 million simultaneous users
Phone booths are old hat, we know that much for sure. But Skype booths? Tallinn Airport in Estonia's capital has become the first site to host a dedicated Skype station, which allows you to video chat with your friends or call them on their phones using Skype credit, exactly as you might do on your computer at home. There's a 22-inch touchscreen up front and a headset nearby, only thing you'll need are some actual friends you want to communicate with. The idea's being put into action by three Estonian companies, all of whom are quite happy to remind us Skype originated in their fine Northern European nation, and the plan is to roll the futuristic-looking booths out to other airports, hotels, shopping malls, hospitals, and the like. In the meantime, Skype usage keeps growing and the company recently recorded 30 million simultaneous users online, breaking its previous record by a trivial three million extra souls.
OMG, FYI, and LOL enter Oxford English Dictionary, foreshadow the apocalypse
In an acknowledgement of the internet's overwhelming influence on the triviality we sometimes refer to as "real life," the Oxford English Dictionary doyens have decided to add a few of the web's favorite pronouncements to their lexicon. Among them are the standouts OMG, LOL and FYI, joining their compatriots IMHO and BFF among the proud number of officially sanctioned initialisms (abbreviations contracted to the initials of their words) used in the English language. Shockingly enough, the expression OMG has had its history tracked all the way back to 1917, while LOL used to mean "little old lady" back in the '60s, and FYI first showed up in corporate lingo in 1941. Not only that, but the heart symbol -- not the <3 emoticon, the actual ♥ graphic -- has also made it in. Just so long as Beliebers and fanpires are kept out, there's still hope for the future. A tiny, twinkling ember of a hope.
University of Central Florida's miniature laser diode aims to speed up networking
The use of laser as a means of data transmission is hardly anything new, but the current crop of laser diodes can only handle so much stress, provided that they don't fail in the first place. Luckily, the geniuses over at the University of Central Florida are about to deliver a smaller yet more intense and more reliable diode, which will lead to many more potential applications even beyond the scope of networking -- think cheaper, more effective hair removal. Little is said about how Professor Dennis Deppe's team made this possible, but once they work out how to optimize the operating voltage for better efficiency, Deppe reckons we'll see diode-embedded high speed, high bandwidth cables in the shops in four or five years' time. Seriously, we'd do anything to keep our latency low for some HD gaming action.
Northwestern University researchers route photon qubit, make quantum internet possible
Big brains across the globe continue to unlock the secrets of the qubit and harness it for myriad uses -- quantum hard drives, quantum computers, and even quantum refrigerators. The internet may be next in line to get quantum-ized now that researchers from Northwestern University found a way to route a photon qubit through an optical cable without losing any of its physical characteristics. A newly developed optical switch does the deed, which allows fiber-optic cables to share multiple users' quantum info at once -- making superfast all-optical quantum communication networks possible -- and gets us closer to having our tweets and status updates whizzing to and fro at the speed of light.

Skype to start serving ads in US, Germany and UK ahead of upcoming IPO
It's a common problem, not having as much cash as you want to, and Skype's solving it with a common web solution: advertising. It may come as a surprise to hear that the eminently popular voice and chat service doesn't peddle stuff to its users already, but it's now formalizing a plan to introduce a carefully controlled measure of paid-for display ads on the Home tab of its Windows desktop client. You heard that right, there's no mention of Mac or mobile services here, and it's further limited to the nations of Germany, the UK, and USA. Anonymous data may be collected as part of the new scheme to target ads to specific audiences (you can, however, opt out), while Skype promises that user experience remains paramount to its future goals, though clearly that looming Initial Public Offering isn't too far from its thoughts right now either.
RIM preparing to bring BBM to iOS and Android, change everything again?
Woah, now here's a juicy rumor to start your Thursday morning off with. BGR reports word from multiple trusted sources that RIM intends to take its BlackBerry Messenger outside the cozy confines of the BB ecosystem and straight into its competitors' app stores. BBM is reputedly all set to make its debut as a messaging app on both iOS and Android, though the specifics of what it might cost you have yet to be ironed out. It'll come in a stripped down version, you'll still need to own a BlackBerry for the full-flavored BBM experience, but that should nonetheless be extremely welcome news for folks finding themselves torn between platforms. The Android version is expected this year, say the sources, while the iOS app may take a little while longer thanks to Apple's more capricious approval requirements.
Verizon dropped 10,000 emergency calls during January snowstorm in Maryland, FCC finds it 'alarming'
Uh oh, Verizon's got itself into a bit of hot water with the old FCC. An outage during a snowstorm last month has reportedly resulted in a whopping 10,000 calls to 911 not being connected by the big red carrier. That would be bad enough in itself, but the less-than-pleased Communications Commission also notes that the emergency services that missed out on these calls were not alerted to the connectivity failure -- in fact, Maryland's Montgomery County officers were the ones to inform Verizon of the fault it was having, which was then promptly repaired within 15 minutes. The FCC is now curtly asking the network to check its entire footprint for similar vulnerabilities -- as the January events were apparently "not unique" -- and to propose remedial actions and monitoring systems to prevent it happening again.
AT&T opens up video archives, shares the history inside
Where can you find Orson Welles, Marconi's daughter, Alexander Graham Bell's grandaughter, and inventors of the transistor and television? You might try To Communicate is the Beginning, a 1976 educational publication tracing the history of electronic communication, which AT&T recently decided to exhume from its archives of Bell Labs material. The 30-minute video's just the first in a series, too, as AT&T's website is already playing host to films about the origins of the laser and integrated circuit too, with more on the way. Find them all at our source link -- you do want to know how your favorite technologies evolved, right?
'Stanford gurus enable two-way radio communications. Over.'
Call it the holy grail of radio transmissions if you must, but even if you're not about to toss that label on it, there's no question that the work being done in Stanford's engineering labs could destroy quite a few preconceived notions about wireless interference. Demoed as a concept last year, a newfangled wireless technology developed in Palo Alto is proving that signals can indeed be sent and received at the same time. Outside of the cellular telephony world, this seemingly simple occurrence doesn't really happen -- typical wireless signals have to take turns when it comes to listening and transmitting. As an example, it's impossible for a WiFi router to "shout" out signals while also being intelligent enough to quiet its own voice in order to hear "whispers" from a connected device. The breakthrough came when researchers found that radios could be tweaked to filter out the signal from its own transmitter, something that already happens within noise-canceling headphones. If this can be packaged into a commercially viable platform, it could instantly double the amount of information sent over existing networks, and on an even grander scale, it could allow airplanes to radio into control towers simultaneously (a feat that's shockingly impossible with today's physics bearing down). Head on past the break for a downright enlightening video on the matter.
Pathpartner demos 720p HD Skype videocalling using Android and OMAP 4 (video)
Putting Pathpartner and Ittiam right beside one another may not have been the best idea if these two were hot-headed, but shockingly, they were treating each other with a great deal of respect within Texas Instruments' MWC booth. All jesting aside, the former's 720p HD videocalling solution is aimed at an entirely different market than that of the latter. Rather than arranging for a four-way video conference, Pathpartner has concocted an Android app that enables 720p video calling over Skype -- you know, that VoIP application that you're already obsessed with. Currently, the company's working with Skype in hopes of getting it 'Skype-certified,' and like Ittiam, it's also chatting with a number of handset makers in hopes of getting it embedded on the phone's software stack from the get-go. Alexy Mathew Joseph, the company's senior technical lead, was on hand to showcase a demo running on a pair of OMAP 4-based development boxes, and the low-bitrate technology that he has helped create enabled smooth, high-def streaming of the call. We should mention that this particular demo was done over an Ethernet network, but he affirmed that it would operate on 3G and 4G networks as well. Also of note, the new software is capable on running on more than just TI equipment, though he wouldn't elaborate other than saying that NVIDIA's Tegra 2 was a platform he hasn't tested on just yet. Just think -- 720p Skype videocalls could be hitting your phone prior to the dawn of 2012, and the carrier's have to be weeping at the mere mention. Vid's past the break, per usual.
Verizon VoLTE voice and video call demo at MWC 2011 (video)
There may not be a native LTE network live in Barcelona yet, but that didn't stop Big Red from hauling a 700MHz demonstration to Spain for the purposes of gloating at Mobile World Congress. We heard just days ago that the LG Revolution would be one of the first phones to support voice over LTE (VoLTE) on Verizon, and today we were given quite a bit of extra information about the rollout. For starters, Verizon's hoping that other carriers adopt their VoLTE platform, even going so far as to encourage it. It's sort of comical to hear the company that once crippled Bluetooth on dumbphones and still makes you buy a month of data just to activate a tablet talk about "openness" when it comes to communications, but we suppose the tables are turned somewhat when it's VZW that stands to gain. At any rate, VoLTE essentially acts as a VoIP lane, giving a specific amount of bandwidth to the call (which ensures call quality, unlike Skype, which is at the mercy of shared applications that are using the same bandwidth) and also enabling the phone to use data whilst the call it ongoing. The Revolution, which is slated to launch in March, will eventually gain VoLTE support, though VZW's not expecting the feature to go live in America until next year. Bilal Wahid, Verizon Wireless' Associate Director of Product Development, told us that at least initially, you may see VoLTE voice and videocalling available on Android smartphones, but there's no reason that the same apps couldn't be developed for other platforms. The call quality was on par with some of the high-bandwidth VoIP calls we've encountered, and the videocalling was particularly impressive. The resolution was tremendous, and there was essentially no lag whatsoever. Of course, this all happened over a locked, modular LTE network, so results will almost certainly vary out in the real world; regardless, it's a beautiful start, and it certainly makes the wait to 2012 that much more difficult. Hop on past the break for a demonstration as well as a lengthy explanation of the technology, where it's going, and when it'll be implemented. %Gallery-116749%
Motorola's Atrix 4G coming to AT&T on March 6th for $200, bundled with Laptop Dock for $500
Don't ever say Ma Bell lacks cahones. On the same day that existing Verizon customers began pre-ordering the CDMA'd iPhone 4, AT&T has come clean with what's next on America's largest GSM network. While announced at CES 2011, pricing and release information had eluded the luscious Atrix 4G... until now, that is. AT&T will begin pre-sales for the Froyo-powered Motorola Atrix 4G Android superphone on February 13th, with the standard $199.99 + two-year contract ($50 more than we were led to believe, mind you) getting one into your grubby mitts. We're told to expect general availability on March 6th "or earlier," putting it just about in line with the date we'd heard rumored. Moreover, those looking to buy will should have a difficult time laying off of the Laptop Dock bundle, which nets you an Atrix 4G as well as a $499.99 dock for the grand total of $499.99 on contract. You heard right -- those who opt to buy the dock at a later time will be asked to shell out five Benjamins, whereas that same tally on day one will also include the phone. It should be noted, however, that the bundle only applies if you also sign your name to a Data Pro plan and tethering add-on, so be sure you're down for that monthly hit before committing in haste. Oh, and just in case you simply can't stop spending, the carrier is also offering an Entertainment Access Kit for Atrix 4G customers which includes the Motorola HD Multimedia Dock, a Bluetooth keyboard and mouse, and a remote control for $189.99.
Egypt comes back online, has a ton of unread feeds to catch up on
Good news for the people of Egypt: internet connectivity has been almost universally restored. Bad news for the people of Egypt: they'll need at least a few weeks to catch up on all the Twitter mentions they've accumulated while being away.
Egypt enters communication blackout with disruption to internet, SMS, and BlackBerry messaging
We don't know what exactly is going on over in Egypt, but the country's government seems to have decided that keeping in touch with the outside world is no longer desirable and has almost completely shut down internet, SMS, and BlackBerry communications. It's not surprising, therefore, that reports are emerging in rather piecemeal form at the moment, though Renesys has hard data showing that almost all routes for exchanging internet traffic with the country have been shut down, with only Noor Group excepted from the block -- a move the internet analytics company theorizes might have been motivated by a desire to keep the Egyptian Stock Exchange online. The reasons for this blackout remain open to speculation and interpretation -- most of which, we remind you, has better destinations than your favorite tech blog -- but its content is clearly an extreme step for any government to take. Check out the links below for further details. [Image credit: seandenigris.com]
Skype 5 for Mac out of beta, group video calling part of Premium subscription
Skype has released the latest version of its communication software; it's out of beta and ready for download. The beta version of Skype 5 for Mac has been available for a little while now, but this is the final version they've settled on, featuring a more minimal interface with simpler views, less whitespace and more information about contacts and communications all condensed in one place. The group video calling that was available for free in the beta has been moved into the Premium subscription model, where it's included with customer support calls for a day pass of US$4.99, or an $8.99 per month subscription. New users get to use the service for free for seven days, so if you just want to try it out, you can do that. Unfortunately, a lot of the feedback on this version so far has been pretty negative, but many of the complaints we saw were about the extra whitespace and window size issues, so maybe this latest version will fix most problems. Skype is available as a free download from the website, and of course Skype Credit and Premium services are an extra charge.
The Daily Grind: Are you a chat Luddite?
So DC Universe Online's voice chat is broken, according to many of the commenters on this and other MMO-centric websites. Ironically, even if the game had no voice chat at all, it would be less broken than the abject disaster that serves as the superhero title's text chat interface. While the game is enjoyable enough in most respects, I scratch my head as to how a development firm with SOE's considerable expertise could scrimp on something as vital as in-game text chat. The cynic in me says that it's because the PS3 version takes priority, but whatever the reason, DCUO's social tools (at least on the PC) are in dire need of someone who cares. That brings up an interesting point regarding voice chat vs. text chat. While third-party programs such as Mumble and Ventrilo have been the norm for "serious" MMO guilds for years now, it's only recently that games have started incorporating voice chat (and players have started expecting it). Sure, voice can be vital for raids, PvP, and challenging endgame content, but is it really necessary (or desirable) for most of the things we do on our way to the level cap? Today's Daily Grind is all about your stance in the voice vs. text chat debate. Are you a chat Luddite? Do you refuse to play a game without voice chat? Inquiring Massively minds want to know. Every morning, the Massively bloggers probe the minds of their readers with deep, thought-provoking questions about that most serious of topics: massively online gaming. We crave your opinions, so grab your caffeinated beverage of choice and chime in on today's Daily Grind!
Nuance opens Dragon Mobile SDK to app developers, we see end to embarrassing dictation
There are some messages that are just too embarrassing to dictate to a human being. Lucky for us and the retired circus contortionist we hired to type up our missives, Nuance is expanding the reach of its transcription software by making its Dragon Mobile SDK available to developers for use in iOS and Android applications. The SDK, which is free to members of the Nuance Mobile Developer Program, sports speech-to-text capabilities in eight languages and text-to-speech in 35. There are already apps out there that can do the job, including Nuance's own Dragon Dictation, but we welcome new advances in automated transcription. You know, it's not exactly a walk in the park dictating an entire Clay Aiken Fan Club newsletter to a guy named Sid the Human Pretzel.
