Eta Devices Have Solution To Long Battery Lives On Smartphones

Imagine this.From now on you no longer have to worry about finding a electricity fix in order to get your smartphone charged every now & then.Won't that be great? Start-up company Eta Devices thinks that it might have a solution in the form of a new technology. The company, founded by a pair of MIT electrical engineering professors, Joel Dawson and David Perreault, has developed a new power amplifier design that results in twice the battery life for certain devices including smartphones.

                            RF power amplifiers change low-power radio signals into high-power signals, but cellphones lose precious power because of the inefficient process in which that is done. Eta has a new technology that makes this a more efficient process although it still has a ways to go before that technology is available in handsets. It will first be seen early next year in LTE base stations before it can be used in something smaller like a smartphone. Currently, it cost $36 billion to power cellular base stations, consuming nearly 1% of global power consumption. 640,000 diesel-powered generators are used to power base stations at a price of $15 billion paid for fuel every year, and this is where Eta's new product will be first applied.

The 5 power amps on the Apple iPhone 5 (the red dots) account for 60% of the phone's power consumption

               The power amplifiers on your phone use power in two modes, output mode and standby. Using the lowest amount of standby power would improve efficiency, but switching from low-power standby to high-power output distorts the signal. Therefore the current technology calls for keeping the levels of standby power high, wasting a lot of electricity just to keep the power on. For high data rate communications, the device keeps more standby power than signal power and this is what makes your phone run hot. Eta's solution is to run different voltages across the transistor and the one with the lowest power consumption is selected. This is done an incredible 20 million times per second. Eta calls this process "asymmetric multilevel outphasing."

The eventual goal of the company is to replace the different power amplifiers on a smartphone with one power amplifier chip. On the Apple iPhone 5, for example, there are 5 such chips. Another power saving feature would be to reduce the number of transmissions your phone makes (your phone is always sending out transmissions even when you are merely downloading a video) to confirm the receipt of packets, or internet information.

Eta hopes to introduce it product in February at MWC in Barcelona, Spain.

iOS 6.0.1 Fixes Issues

Yesterday,a small update was released to iOS OTA(over the air).The update is supposed to fix an issue with horizontal lines over the keyboard of the iPhone 5, camera flash issues, Wi-Fi reliability and more.

Here is the full changelog from Apple:
1.Fixes a bug that prevents iPhone 5 from installing software updates wirelessly over the air.
2.Fixes a bug where horizontal lines may be displayed across the keyboard.
3.Fixes an issue that could cause camera flash to not go off.
4.Improves reliability of iPhone 5 and iPod touch (5th generation) when connected to encrypted WPA2 Wi-Fi networks.
5.Resolves an issue that prevents iPhone from using the cellular network in some instances.
6.Consolidated the Use Cellular Data switch for iTunes Match.
7.Fixes a Passcode Lock bug which sometimes allowed access to Passbook pass details from lock screen.
8.Fixes a bug affecting Exchange meetings.

Google Drive Updated

             A few new features have been added to Google Drive through this update.For those who doesn't know what Google Drive is,it is Google's online cloud based storage in reply to Dropbox.

                The new features include easy sharing (or embedding) of your Drive files to popular social networks such as Google, Facebook, Twitter, Gmail, etc.

Here is how to share a file from Drive to Google+:

1.From within Google Drive, open the file or document you want to share.

2.Copy the file’s URL from your web browser’s address bar.

3.Paste the URL into the Share box at the top of your Google+ stream. If you’re signed into another Google   service, like Gmail, you can also use the + Share button, which you’ll see in the upper right corner of your browser window.

4.Select a circle or type the name of individual people you’d like to share your post with.

5.Click the Share button.

And here is how to share a document straight from within it.

1.From within Google Drive, open the document and click Share in the top right corner of your browser window.

2.Make sure the file’s sharing settings are listed as “Public on the web” or “Anyone with the link.” If your file is private, your friends and family on Google+ won’t be able to access it.

3.Click on Google + next to the Share link via… option at the top of the sharing menu. You’ll see the Google+ share box with the embedded document.

4.Select a circle or type the name of individual people you’d like to share your post with.

5.Click the Share button.

                         Thus the sharing is now easier with Google Drive .

Nexus 3 Leaked

As we already know that the new Nexus devices are being christened after their screen sizes. A device called Nexus 3 has popped up in the EXIF data of a Google Switzerland employee and he claims the EXIF data has been modified.

                  To be more specific, the person, in his October 28 post containing the two pictures, stated that “we get to test some things before they’re launched, but for everything else, there’s exiv2.org”. We all know that EXIF data can be modified but let’s just stop and speculate for a second on why would a Google employee take his time to edit the information in such way before publishing it on his Google+ page?

Maybe he is trying to attract our attention.The images are those types of images which a typical user would simply upload from the device directly to Google+. In this case there was an extra step in modifying the EXIF data, as claimed.

Nokia Has Announced Cheap Nokia 109

Remember those small,old Nokia phones which had monstrous battery lives ?Well,Nokia has just announced the Nokia 109 entry-level phone. It packs a 1.8-inch TFT screen with 128x160 pixels resolution, dual-band GSM/EDGE connectivity, FM radio and microSD card.
                         Nokia 109 runs on S40 platform and comes with Nokia’s Xpress Browser, which compresses the web pages up to 90% and saves you data traffic.A few social apps are also pre-installed .
The phone's dimensions are  110x46x14.8 mm and it weighs just 77 grams. According to Nokia the battery will last 33 days in stand-by.Impressive!
