Google has released a smartphone tradition with the Nexus name each time releasing the latest version of Android.

Google always took the phone vendor to produce the Nexus. Typically, Nexus has always been a bone of contention phone vendors such as Samsung, HTC, and Motorola.

As reported by Digitimes, Google indicated chose Samsung as the manufacturer of the Nexus fourth generation will carry Android 5.0, codenamed Jelly Bean.

“Since Samsung has become a leading vendor Android smartphone, Google will continue to cooperate with Samsung to develop fourth-generation smartphone Nexus,” the source said.

Samsung re-elected to the possibility of a vendor who manufactures the Nexus series, it will enhance the Samsung as a company focused on the Android platform.

Actually, LG and HTC vendors also participate in the bidding to be the manufacturer of this series next Nexus. But if this news is true, Google has chosen Samsung and become winners in the contract.

Samsung has been producing three times in the Nexus. For the next generation Nexus, Samsung seems to be selected again by Google.

Nexus model first, Google took to produce the HTC HTC Nexus. The device is still implementing the Android 2.2 or Froyo for the first time.

The second model, Google took Samsung to manufacture Samsung Nexus S, which is an example of implementation of Android 2.3 or Gingerbread.

The third model, the Samsung again won the project to produce Galaxy Nexus.

Form similar to the Samsung Galaxy Nexus Nexus S with a curved screen that is more flexible now in hand to follow the curve of the human body. Although similar to its predecessor, the form factor Galaxy Nexus slightly thinner (8.94 mm) and slightly heavier (135 grams).

The plan, Google will release its fourth-generation Nexus is in the fourth quarter-2012.

With the release schedule at the end of the year, certainly will not interfere with the release schedule smartphone from Samsung, in particular smartphone Samsung Galaxy S III is scheduled to be released earlier this May 2012.

Sophisticated cameras from MIT

The next few years, a person’s privacy may become less safe. Thanks to sophisticated technology, the individual one can interfere with the privacy of other individuals. For example, in the photography world, has now found a camera that can penetrate walls. With this camera, though hindered bulkhead wall thickness, the photographer can still take pictures.

Camera that can shoot behind these thick walls, is the result of researchers at MIT’s Camera Culture Research Group. Not long ago, they’ve managed to find a method to do just that.

“People familiar with the echoes, but echoes of light can also be used,” said researcher told of the Camera Culture Research Group MIT Ramesh Raskar, Tuesday, March 20, 2012.

The principle of echo applied to the laser light to see objects hidden in the corner. Laser fired from the camera to a second wall which is opposite the barrier wall. By uneven wall surface, the laser will be scattered throughout the room. Some of the particles of light will reach the surface of hidden objects and reflected back to the wall in front of him. From the wall, the light returned to the camera.

Although released simultaneously, the laser wave back to the camera in a different time. Arrival time difference is measured by a camera with shutter speeds of up to two picodetik (2 a trillion per second).

Laboratory tests carried out by hiding behind a wall made dolls. Their homemade cameras managed to see the shape of the doll. Although not reflected accurately the form of dolls, but testing can accurately reveal the body of the photographed object.

Behind the camera, the researchers set up a computer equipped with software that can map the laser feedback. “Processing using mathematical techniques,” he said.

Unfortunately they have the computer software is still too slow to process the data so much. Currently it takes a few minutes to get the whole picture. They hope in the future could peek behind the objects in the room no longer than 10 seconds.
