8 MP camera phones OmniVision 8850 OV smallest sensor with 1.1 micron-sized



Looks like the energizer technologies are vying to make the device smaller. Having previously contained nano-sized batteries, is now emerging super mini-sized mobile phone camera, only 4.7 millimeters. The camera is made ​​using 1.1 micron sensortechnology.

Although small, this camera has a pretty good quality. This camera can produce images with quality 1080p resolution at 30 fps mode. Not enough with that, this camera is also capable of producing images on HD 720p 60 fps mode.
OmniVision camera which is a supplier to Apple said that the OV8850 will not be usedfor the latest generation iPhone. They say they have had problems with theprocurement of production in the last month.
Thanks to the 1.1 micron sensor, this camera has some features include on-chiptemperature sensor, two PLL, context switching, 4 Kbits one-time programmablememory, lens shading correction, detective pixel canceling, black sun elimination.

Was the Space Shuttle a Mistake?


Forty years ago, I wrote an article for Technology Review titled "Shall We Build the Space Shuttle?" Now, with the 135th and final flight of the shuttle at hand, and the benefit of hindsight, it seems appropriate to ask a slightly different question—"Should We Have Built the Space Shuttle?"

After the very expensive Apollo effort, a low-cost space transportation system for both humans and cargo was seen as key to the future of the U.S. space program in the 1980s and beyond. So developing some form of new space launch system made sense as the major NASA effort for the 1970s, presuming the United States was committed to continuing space leadership. But it was probably a mistake to develop this particular space shuttle design, and then to build the future U.S. space program around it.

The selection in 1972 of an ambitious and technologically challenging shuttle design resulted in the most complex machine ever built. Rather than lowering the costs of access to space and making it routine, the space shuttle turned out to be an experimental vehicle with multiple inherent risks, requiring extreme care and high costs to operate safely. Other, simpler designs were considered in 1971 in the run-up to President Nixon's final decision; in retrospect, taking a more evolutionary approach by developing one of them instead would probably have been a better choice.

The shuttle does, of course, leave behind a record of significant achievements. It is a remarkably capable vehicle. It has carried a variety of satellites and spacecraft to low-Earth orbit. It serviced satellites in orbit, most notably during the five missions to the Hubble Space Telescope. On a few flights, the shuttle carried in its payload bay a small pressurized laboratory, called Spacelab, which provided research facilities for a variety of experiments. That laboratory was a European contribution to the space shuttle program. With Spacelab and the Canadian-provided robotic arm used to grab and maneuver payloads, the shuttle set the precedent for intimate international cooperation in human spaceflight. The shuttle kept American and allied astronauts flying in space and opened up the spaceflight experience to scientists and engineers, not just test pilots. The space shuttle was a source of considerable pride for the United States; images of a shuttle launch are iconic elements of American accomplishment and technological leadership.

Nokia's N9 surprise - MeeGo, not Windows Phone 7


At least, the next six months is, after the largest mobile phone manufacturer in the world surprised just about everyone at the Nokia Connection event in Singapore today by not announcing its first Windows Phone 7 device.

Nokia hopes the new N9 smartphone will be available in Australia before the iPhone 5 arrives, most likely in September.

That's important, because the Finns have put everything they've got into creating a phone that's as un-Nokia as its recent poor forays into smartphones and as Nokia as the original simple design that saw it sitting virtually unassailable on top of the world through the 90s.

They've even asked Apple fans what they think of it.

"One of the workshop groups was heavily skewed with Apple fans," Chris Carr, Nokia's managing director in Australia and New Zealand, told news.com.au.


"The ones who had previous history with a Nokia device saw this as a real opportunity to move back to the brand.

"The Apple-only users — mostly younger users — were struggling to see how this device fitted in."

The rest, Mr Carr said, were overwhelmingly positive about the new design, the new interface and the most importantly, the return of MeeGo, the operating system that worked so well for the N900 nearly three years ago when it was known as Maemo 5.

The N900 was arguably the last credible success for Nokia, a geek's darling for its QWERTY keyboard and smooth touchscreen as well as its ability to consolidate contacts and notifications years before iOS and WP7 got around to it.

N9 will be around the $700 mark for a 16GB version, with up to a 64GB version also available.

It’s 3.9" screen is made from Gorilla Glass (read "tough") and the body is a single piece of polycarbon that’s colour-infused with either black, cyan or magenta. That means it you scratch it, it stays black, cyan or magenta.

It also means better reception, or as Nokia's senior vice president of design Marko Ahtisaari puts it, "unlike some products, you don’t need to hold it a certain way". Bam.

It also supports Nokia’s new free Maps service, which are integrated into the phone, require no downloading and automatically update. They're 3D too...

Near Field Communication technology helps do away with a lot of Bluetooth headaches. Mr Ahtisaari demonstrated a set of Nokia speakers with NFC built in. Simply touch the N9 to the speakers and instantly they pick up and play whatever music you’d been listening to on your phone.

Most importantly for Nokia, the N9's beauty is all in the swiping. One of their grander statements today came from Mr Ahtisaari, who claimed "the swipe is a big human fundamental gesture".

"It’s global — easy to learn and easy to do," he said.

Swipe from anywhere along the edge of the N9's screen and you’ll get taken home. From there, Nokia have identified the three screens most users, well, use.

The first swipe from a home page containing nothing but a clock takes you to Applications. The next brings up events and notifications and the final screen shows all your open applications.

And that’s it. Most importantly, it works — smoothly, even — mainly because it’s not Symbian.

It could have been much worse. The growing horror in the conference room today was palpable as assorted tech media and industry types waiting for the big WP7 announcement were walked through an hour of praise for the new Symbian upgrade.

Surely Nokia weren't sticking with a millstone that had for the large part helped drag their share market down some 40 per cent in their home country, saw them arguing with Apple about who's the new most valuable mobile brand, and shed 8800 jobs recently?

No, they weren’t.

"Symbian Anna" is a key part of Nokia’s push into South-East Asia Pacific, where they hope their budget friendly phones will snap up part of a market that’s expected to grow 40 per cent in the next four years.

Ten new Symbian phones in the next 12 months will help Nokia "connect the next billion".

So far so good. But where’s our Nokia Windows Phone 7? Nokia says the N9 is its new "hero phone", so does this catapult MeeGo phones to the top of the heap?

Not at all, says Mr Carr. The first WP7 phones will be rolled out next year.

"Nokia started with MeeGo three years ago... it wasn’t something we started in the last 12 months," he said.

"We'll still do Windows Phone regardless of (the N9's) success and bring it to Australia in first half of next year."
