The laser unprinter – Now you can erase the prints

A team of researchers from the University of Cambridge in England have created a laser unprinter that can remove ink without damaging the paper.

Using the unprinter technology you can remove the prints on the paper and you can reuse the paper for printing. The main reason for this technology to cut down the carbon usage while making and recycling the papers.

Recycling paper is definitely a step in the right direction, but it’s still a very resource-intensive process. But using the unprinter technology we can simply delete the prints on the paper and re-use for printing.

T r u e C r y p t powerful on-the-fly disk encryption software for Windows, MAC, and Linux


T r u e C r y p t is a powerful free and open-source on-the-fly realtime disk encryption software. T r u e C r y p t supports nearly all operating systems, includes Windows, Mac OSx, Linux.

Features:

* Creates a virtual encrypted disk within a file and mounts it as a real disk.
* Encrypts an entire partition or storage device such as USB flash drive or hard drive.
* Encrypts a partition or drive where Windows is installed (pre-boot authentication).
* Encryption is automatic, real-time (on-the-fly) and transparent.
* Parallelization and pipelining allow data to be read and written as fast as if the drive was not encrypted.
* Encryption can be hardware-accelerated on modern processors.
* Provides plausible deniability, in case an adversary forces you to reveal the password:
Hidden volume (steganography) and hidden operating system.

Smart Optimus 1.6TB SSD, 1GB Per Second read speed

Smart Modular Technologies introduced today an enterprise level SSD (Solid Sate Drive) that has just about the largest capacity and fastest reading speed of any SSD on the market right now. Called the Optimus, the SSD boasts capacities from 200GB up to 1.6TB and read speeds of up to 1GB per second, all packed into a 2.5-inch form factor.

The Optimus SSD uses a Serial Attached SCSI (SAS) 6Gb/s interface that offers 1000MB/s read speeds and 500MB/s write speeds. It comes in capacities of 200GB, 400GB, 800GB, and 1.6TB. And, since it’s targeting the enterprise market, it also promises to be fail-safe with an added range of technologies, including FlashGuard, DriveGuard, and EverGuard, to ensure the safety of your data and the longevity of the drive. Smart Modular even offers a 5-year warranty.

Phillips will develop efficient replacement for 60W normal light bulb

Phillips recently won a competition to develop a energy efficient replacement for 60W normal bulb. The new bulb was tested for 18 months in the lab and in the field. The testing exposed the light to extreme humidity, temperatures, vibration, and voltage changes. The Phillips bulb uses only 10W to produce the same brightness as a 60W normal bulb for an 83% energy savings per bulb.

The bulb may hit the stores next year with the expected price of $18.

Patent Wars

Google’s Senior Vice President and Chief Legal Officer David Drummond posted an article in Google’s official blog (Google Blog) regarding the recent patent complaints and compaigns by others such Apple, Microsoft and Oracle on Android related patents. From the date of first release of Android, the Google’s flagship mobile operating system facing many patent claims.

After a group (CPTN and Rockstar) includes Microsoft, Apple and others bought patents from Nortel and Novell, threats relarding patent cliams increased.

David claimed that the groups trying to use fake patent claims to threaten Android developments and trying make money from royalties. He also claims that these groups may bought these patents to use only to threaten others.

“They’re doing this by banding together to acquire Novell’s old patents (the “CPTN” group including Microsoft and Apple) and Nortel’s old patents (the “Rockstar” group including Microsoft and Apple), to make sure Google didn’t get them; seeking $15 licensing fees for every Android device; attempting to make it more expensive for phone manufacturers to license Android (which we provide free of charge) than Windows Phone 7; and even suing Barnes & Noble, HTC, Motorola, and Samsung. Patents were meant to encourage innovation, but lately they are being used as a weapon to stop it.”, said David.

New laser technology could kill viruses and improve DVDs


A team led by a professor at the University of California, Riverside Bourns College of Engineering has made a discovery in semiconductor nanowire laser technology that could potentially do everything from kill viruses to increase storage capacity of DVDs.

Ultraviolet semiconductor diode lasers are widely used in data processing, information storage and biology. Their applications have been limited, however, by size, cost and power. The current generation of ultraviolet lasers is based on a material called gallium nitride, but Jianlin Liu, a professor of electrical engineering, and colleagues have made a breakthrough in zinc oxide nanowire waveguide lasers, which can offer smaller sizes, lower costs, higher powers and shorter wavelengths.
