Google announced the company apart in the normal business operations, is also developing the technology allows automatic driving vehicle. The company said in a blog, using this technology can reduce by half the number of deaths due to traffic accidents worldwide each year about 60 million lives saved. At the same time Google also hopes to reduce carbon dioxide emissions.
Two recent announcements have made self-driving cars seem a lot closer to reality. The first comes from the Army, which is now using self-driving vehicles to guard a large military facility and nuclear waste dump in Nevada. And then there's Google, which recently announced that it has developed self-driving cars that have logged over 100,000 miles on real roads in real traffic.
What is going on inside these cars to make it possible for them to drive themselves? Let's take a look.
You could, in theory, turn any car into a self-driving car. The first thing you would have to do is make it possible for a computer to control the car. This is not quite as easy as it sounds, but it is relatively straightforward. The computer needs to be able to turn the steering wheel, push the accelerator and brake pedals, move the gear shift control and start the engine.
These tasks, at least in experimental self-driving cars, are often accomplished with motors. A motor is mounted so it can turn the existing steering wheel. Another motor is able to put pressure on the accelerator and brake pedals. And so on. It is not a particularly elegant solution, but it gets the job done. As production cars become more advanced, drive-by-wire systems are becoming more common. In cars with drive-by-wire, a computer can hook directly into the existing control systems.
The next thing that a self-driving car needs is sensors, and here things get pretty complicated today. A human being drives a car by using his or her eyes as the sole sensor. The human visual system is amazing in this regard, because it is able to accurately judge the presence of obstacles, their distance, their relative size based on distance, their speed, etc. A human being also recognizes what he is seeing. If a human being sees a fence, she can accurately predict with high certainty that it will not jump into the middle of the road. On the other hand, a child playing with a ball on a sidewalk is a different story.
Computer vision systems are nowhere near this point in their development. So they rely on extra sensors to provide more information. Self-driving cars do have camera-based vision systems that they use to see other cars, unexpected obstacles, road markings and signs. But in addition, self-driving cars almost always have GPS sensors so that they have a better idea of exactly where they are and where they are pointing. They also have LADAR systems — laser scanners that can look for nearby objects and accurately judge their distance. They may have RADAR systems as well. They may also have infrared sensors to improve night vision.
These sensors all feed into a powerful onboard computer (often multiple computers) that process all the data that the sensors are gathering. The internal computer will have access to a database of maps and other relevant information. For example, engineers may pre-drive a route and pre-catalog all signs, road markings, curbs, crosswalks, traffic lights, etc. that the self-driving car will encounter along the road. This way, the car knows what to expect and can plan accordingly. Finally, the onboard computer may also be communicating by radio with bigger computers holding even more data.

Windows Phone 7 is the last hope for Microsoft
Many people say that Windows Phone 7 is the last hope of Microsoft in the smartphone market, indeed, it is vital time for Microsoft. Although the smart phone market is fiercely competitive, but Microsoft is no other choice. Microsoft's main concern is their own economic interests, but also those who like HTC, ihkc that old cell phone manufacturers also want to see other companies compete with each other. So what kind of advantages of Microsoft's new mobile operating system Windows Phone 7 in the end?
The world's largest software company is hoping that the new phones, from handset makers Samsung, LG, HTC and Dell, will propel it back into the mobile market, which many see as the key to the future of computing, reports the Daily Mail.
The new phones, initially available on the T-Mobile network in Britain and on AT&T in the US, are much closer in look and feel to Apple's iPhone , with colourful touch-screens and 'tiles' for easy access to email, the Web, music and other applications.
Ballmer, who has admitted that his company 'missed a generation' with its recent unpopular phone offerings, said the new phones would eventually be available from 60 mobile operators in 30 countries.
Meanwhile, at a simultaneous launch event at London's Institute Of Contemporary Arts (ICA), Microsoft announced that WP7 will be coming on the Dell Venue Pro by Christmas.
Dell's Venue Pro will join five other WP7 handsets - three from HTC and one each from LG and Samsung - in the British market in the coming months.
In the US, the first phone from AT&T, priced at $200, will be available Nov 8.
Six Windows Phone 7 handsets will be released in Britain in the coming months, including three from HTC and the Dell Venue Pro, which is the only model to come with a slide-out keyboard
Microsoft has a market share of only five percent in the global smartphone market, according to research firm Gartner, compared with nine percent a year ago.

Apple ipad vs sumsung Galaxy Tab，exposure of the U.S. contract price
Samsung Tablet PC Galaxy Tab technical details have been revealed, but its pricing and release time is still not resolved the two key issues. U.S. network operator T-Mobile's unofficial blog Tmonews on Sunday revealed the details of this release tablet.
The Galaxy Tab, with its 7-inch display, but a smaller surface than the competition from Apple, but the memory SD card up to 64GB of expandable by.
This offers the Samsung all-rounder a 3.2-megapixel camera – the iPad users are still waiting in vain for this extra. Highlight: The video call feature with an additional 1.3-megapixel camera! Again, the iPad) do not keep up (.
About the Android smartphone operating system are all the apps as well as in normal available.
Great advantage of the Galaxy Tab also: the handy design. The Samsung Galaxy Tab is not much bigger than an outstretched hand, fits in any pocket. And with 380 grams almost half as light as the U.S. bestseller.
Even e-books look good on the tab from right, Bluetooth, music can be transferred. Important for users to the Internet and share the Samsung supports Flash – Apple’s archenemy.
O2 Galaxy tab from the end of October depending on the tariff rates from 99 EURO to 759 EURO one-time payment or for the offer.
These then are still costs for data volume and any flat rates. Early reports is Tablet PC on the market cost of at least 640 EURO.

Wal-Mart will sell Apple iPad tablet PC on October 15
Wal-Mart will sell Apple iPad tablet PC in hundreds of stores on October 15, and to expand sales outlets to over 2,300 stores in mid-November, the cheaper models start at 499 dollars. Integrated media reported on Oct. 13, Wal-Mart Stores Inc will begin selling Apple's iPad tablet on Oct. 15. Wal-Mart said the first time sale iPad tablet pcs in hundreds of stores, and then will be expanded to more than 2,300 sales outlets stores in mid-November.
A distribution deal with Walmart adds significantly to the iPad’s retail availability over the holidays: the device is now on sale via Amazon.com, and recently appeared at discount retailer target. The iPad has been on sale at electronics retailer Best Buy since its launch earlier this year.
Walmart is known for bringing products to customers at discounted prices, but it looks like its pricing on the iPad is going to match pricing available from Apple and it’s other retail partners: the Wi-Fi, 16 GB model will be available for $499. So far, only Target has been able to set up a discount, with owners of Target credit cards being able to get a 5 percent discount on an iPad. Walmart will be offering the iPad through its site-to-store service, however, which offers free shipping of online orders sent to a local Walmart store for pickup.
Apple’s ability to move the iPad into major retail channels this holiday season may be key to the device maintaining its lead current in the tablet computing arena. A slew of Android tablets—debatably led by the Samsung Galaxy Tab —are getting ready to land at retailers.

Google attack on Microsoft and Apple in the laptop market
Just after the shock of the mobile phone market, Google's war to start immediately in the laptop market. He directed to the two giants Microsoft and Apple.
Having shaken up the mobile phone market, Google is now preparing to compete head-on with Apple and Microsoft in laptop computers with a range of Google-based "netbooks" due out this year.
Glen Murphy, the Australian lead designer on Google's Chrome operating system (OS) and web browser projects, said the first Chrome computers would go on sale this year. The big vendors have signed up including Samsung, Acer, Asus, Toshiba and HP.
"Mostly Chrome OS is a browser; it's really just a way of letting you buy a computer and have the web be at the centre of the experience," said Murphy.
"We look at what everyone's doing with computers today and by and large most people only ever need the web."
Many computer users now do all of their chatting, emailing, reading, video watching and even word processing inside a browser but video games on the PC have always operated independently. But soon, Google will release a new version of Chrome with support for hardware-accelerated graphics, a feature also offered in the recently unveiled beta versions of Internet Explorer 9 and Firefox 4.
Chrome OS is a separate project to Google's Android platform for smartphones. Several Android tablets are due out by the end of the year, including Dell's Streak and Samsung's Galaxy Tab.
"Android is very focused on the best mobile experience there is, Chrome is very focused on the best web experience there is - obviously those things aren't mutually exclusive," said Murphy.
He said the Chrome project formed out of the frustrations of Google's army of web developers, who were hitting the limits of what browsers could do when creating web applications.
"We wanted to build the best browser there was and if our competition decided to do the same things then that would be awesome - at the end of the day it's not about getting Chrome everywhere, it's about making the web better," he said.
