Google teste des lentilles intelligentes pour les diabétiques

0 commentaires



 Google teste la  nouvelle méthode de mesure de la glycémie a l'intention des diabétiques qui fait appel à des lentilles de contact intelligentes, a fait savoir jeudi la firme américaine.


Pour l'instant à l'état de prototypes, ces lentilles 
intelligentes munies de microprocesseurs miniaturisés et connectés permettent de suivre l'évolution de la glycémie seconde par seconde en analysant le contenu des larmes, ce qui permettrait aux diabétiques de ne plus avoir à la mesurer en se piquant le doigt plusieurs fois par jour.


"Nous sommes en discussions avec la FDA (l'agence de sécurité sanitaire américaine), mais il y a encore beaucoup à faire pour que les gens puissent utiliser cette technologie", dit Google sur son blog officiel, ajoutant être à la recherche de partenaires pour la distribution.
Le géant des services en ligne, qui cherche à se diversifier, notamment dans le secteur de la santé, a créé en septembre une filiale vouée à la lutte contre les affections dues au vieillissement.

How are new iPhones faring in Japan?

0 commentaires

 
NTT Docomo provided some visibility into iPhone sales in Japan, when that country's largest carrier reported earnings on Friday. Most of the news -- but not all of it -- was good.
First, the bad news. Docomo, which began offering the iPhone for the first time in the fall of last year, said group operating profit fell 2 percent in the April-December period and sales were slightly off, according to a Nikkei report.
The addition of the Apple phone also increased Docomo's "discount costs," according to Nikkei.
The Good news: So-called "customer outflows" (to rival carriers, for example) dropped from 130,000 in September to 50,000 in December, the company said.

And KDDI, which also reported earnings this week, said iPhone sales are up. Softbank has yet to report earnings.Also in December, the carrier saw a net increase of 279,000 subscribers, beating rivals KDDI and SoftBank -- the first time in two years that's happened.
The iPhone -- thanks in part to Softbank, which began carrying the phone in 2008 -- has been popular in Japan, forcing carriers like NTT Docomo -- which had long resisted the iPhone -- to embrace it.

PlayStation Vita Slim is thinner, cheaper with better battery life, but gambles on a new screen

0 commentaires
Sony is trying to give its Vita handheld a shot in the arm with a new Slim version. The fresh, slender games machine is already out in Japan, but is finally making its way to the western world.
Specifically, the Slim, also known as the Vita 2000, is coming to the UK on 7 February, for an estimated £180 -- £50 cheaper than the original Vita was when it launched. There's no confirmed US release date yet, but I'd be surprised if stateside readers had long to wait.
The Vita Slim is -- as the name suggests -- smaller and lighter than its chunky predecessor.
Holding it in your hands you'll notice that it feels very light, though the Slim model is still a large device that you'll struggle to squeeze into your pocket alongside a phone and wallet. Instead, this bulky handheld will require a backpack or handbag.

 

New display

Slimmed-down size aside, the biggest change here is that the Vita's 5-inch display has been tweaked. The impressively high resolution remains, but instead of OLED, that broad panel now deploys LCD technology.
OLED is tough to beat in terms of image quality, so it'll be interesting to see how the new screen compares in a side-by-side battle. It may be that the quality has been dropped slightly in order to make the Vita slightly cheaper.
 

Under the hood

There are a few other tweaks to the Vita hardware, all of which are welcome. To start with, you'll get 1GB of on-board storage, which means you'll have room to store some games straight-out-the-box, and will slightly decrease your reliance on memory cards.
Sony has mercifully ditched its proprietary charging port in favour of a Micro-USB socket. This is the same charging input that many gadgets (Android phones and the Amazon Kindle for instance) use, so you may already have several Vita Slim-compatible cables lying around your house.
 
Sony says the new Vita has better battery life too. Up to six hours of gaming is promised, which isn't jaw-droppingly spectacular, but is at least several hours more than the original Vita lasted.
In Japan, the Slim comes in a variety of charming colours, but unfortunately the UK model will only come in black, Sony tells me.

Outlook

The Vita Slim brings several welcome changes, and certainly makes Sony's handheld a more tempting prospect. It has a huge fight ahead though -- as well as competing with Nintendo's 3DS console, the Slim must fend off the likes of the iPhone, iPad, and a broad range of Android gadgets, many of which are being used for gaming.
Are you tempted by the Vita Slim? Have your say in the comments, and stay tuned for a full review coming very soon.

Inside G Flex: LG's long and winding road to setting the curve

0 commentaires
With the curvy G Flex, it's LG -- and not Apple -- that is showing it can "think different."
The G Flex, which arrives in the US via Sprint stores on Friday, with AT&T and T-Mobile following suit in the next few days, shakes up the normal conventions of the flat, rectangular slab of a touch-screen device pioneered by the iPhone. It was one of two curved phones that debuted late last year, the other being Samsung Electronics' Galaxy Round.
The immediate benefit is obvious: The curved design better conforms to your face, offers a better video-viewing experience, and theoretically a superior sound. Longer term, the G Flex sets the groundwork for a fully flexible, and far more durable, smartphone. Perhaps most important, however, may be the phone's ability to bend the perception of LG itself.
The company, which has long languished in the shadow of the larger and flashier Samsung, could be poised for a breakout year. With hits such as the Google-branded Nexus 5 and the G2, and now the G Flex, LG could finally shed its also-ran status in mobile and inject some serious competitive pressure in a field dominated by Apple and Samsung.
"A high profile, hero phone, first to market in its form factor, could really help reset people's expectations and confidence in LG, and it is hitting at a good time," said Stephen Baker, an analyst at NPD.
Mobile was a bright spot when LG reported its fourth-quarter results on Monday, with the unit seeing sales rise 28 percent. The company shipped a record 13.2 million smartphones in the period, up 54 percent from a year ago.
LG's steady progress comes in contrast to the myriad companies that have struggled to turn a profit at a time when consumers are primarily flocking to an iPhone or Galaxy S smartphone. Even Google ended up dumping Motorola Mobility onto Lenovo after successive quarters of losses. LG's share of the global market rose to 4.5 percent from 4 percent a year ago, according to Strategy Analytics. That's tiny relative to Apple or Samsung, yes, but it's growing at a time when other players are seeing their own position erode.
The G Flex could potentially accelerate its ascent. It is by no means a guaranteed blockbuster, with its 6-inch display potentially turning off consumers agitated by the "phablet" category of oversize phones, and its $300 on-contract price tag steeper than the normal flagship device. It also lacks the marketing heft of Samsung or the rabid following of Apple.

Still, it's won some critical praise, including from CNET editor Lynn La, who said in her review that the G Flex was a "memorable device with plenty of potential," and called the curved shape "more than just a party trick."
Even if it ends up as a niche product, it will have achieved what LG has long sought: legitimate buzz. As I've written before, LG's biggest public image problem is that it doesn't have one. It makes decent phones, including several worthy budget models, but is barely on anyone's radar.
LG certainly has a lot riding on the G Flex. It has spent more than five years developing the phone, coming up with the concept and driving different lines of LG's businesses to help make it a reality. LG envisions G Flex to be the start of something big for the company.
"Curved phones are a major branch of our tree," said Chul Bae Lee, the head of design for LG Mobile responsible for the hardware and software of the G Flex. In a recent interview with CNET, Lee discussed the origins of the G Flex and the future of bendable phones.
Because we can... 
The G Flex was started on a whim.

Well, LG probably wouldn't characterize it so flippantly, as the phone required years of planning and a massive amount of cooperation with different parties. More than five years ago, a small group of designers began looking at where mobile phone design was headed, and began playing with the idea of phones that were flexible, foldable, and ones that you could even roll. After countless meetings and discussions about what was and wasn't feasible, they ultimately just made the decision to go with it.
"It was a starting point for us," Lee said. "We figured if we can do it, we should try it."
The problem: The unique parts necessary to build such a phone didn't yet exist.
Which is one of the primary reasons why the G Flex is unique. Typically, a smartphone -- even a high-end one -- is designed and built using components that are available, or at least visibly coming down the road.
LG, like Samsung, is a massive conglomerate with its hands in multiple businesses, several of which provide key components to various smartphone companies. Over the last few years, LG has begun to more fully take advantage of the resources of its sister units.
The Optimus G, for example, was hailed as the first smartphone to use top-shelf LG-made components, including the battery from LG Chemical, the screen from LG Display, and the camera module from LG Innotek.
But the Optimus G used the best parts available. For the G Flex, LG Electronics had to push its sister companies to come up with something new. It's a subtle, but significant difference.
