UC Santa Barbara solid state lighting team develops the first m-plane nitride based nonpolar vertical-cavity surface-emitting lasers (VCSELs) In a leap forward for laser technology, a team at University of California, Santa Barbara, has developed the first violet nonpolar vertical-cavity surface-emitting lasers (VCSELs) based on m-plane gallium nitride semiconductors.
The XDModo Window solar charger sticks to the inside of a glass window pane so that the PV panel gets maximum exposure to the sun. I guess I'm lucky that I now live in a part of the world blessed with long sunny days that are perfect for juicing up the battery on my solar device charger.
STMicroelectronics has introduced the industry’s first digital radio chipset that enables simultaneous reception and processing of AM/FM and multiple digital-radio broadcasts (e.g. DAB+). Complete with full software stack and support for a number of different broadcasting standards, ST’s new digital radio chipset started volume production in Q2 2012.
Integrated Device Technology, Inc. today announced that it has acquired NXP’s high-speed data converter assets and Alvand Technologies, a leading analog IP company specializing in data converters. Terms of the deals were not disclosed. These transactions solidify IDT’s leading position as a comprehensive solutions provider for wireless infrastructure.
The 100-plus-year history of the automobile is checkered with failed technologies. Some of these features and functions are so bad that car manufacturers would rather you not recall them at all. To suss out the most spectacular tech mistakes of yesteryear, we spoke to car experts about their all-time favorites.
The amount of structural damage that radiation causes in electronic materials at the atomic level may be at least ten times greater than previously thought. That is the surprising result of a new characterization method that uses a combination of lasers and acoustic waves to provide scientists with a capability tantamount to X-ray vision: It allows them to peer through solid materials to pinpoint the size and location of detects buried deep inside with unprecedented precision.
UCLA researchers have developed a new transparent solar cell that is an advance toward giving windows in homes and other buildings the ability to generate electricity while still allowing people to see outside. Their study appears in the journal ACS Nano . The UCLA team describes a new kind of polymer solar cell (PSC) that produces energy by absorbing mainly infrared light, not visible light, making the cells nearly 70% transparent to the human eye.
U.S. Naval Research Laboratory scientists from the Radio Astrophysics and Sensing Section of the Remote Sensing Division in conjunction with radio astronomers and engineers from the National Radio Astronomy Observatory (NRAO), Socorro, N.M., achieve "First Light" image, May 1, 2012, at frequencies below 1-gigahertz (GHz) on the Jansky Very Large Array (JVLA).
Big data needs big power. The server farms that undergird the Internet run on a vast tide of electricity. Even companies that have invested in upgrades to minimize their eco-footprint use tremendous amounts: The New York Times estimates that Google, for example, uses enough electricity in its data centers to power about 200,000 homes.
Google has acquired iOS and Mac email client Sparrow, with the team behind the popular app heading to Google to work with the Gmail team. “We care a lot about how people communicate, and we did our best to provide you with the most intuitive and pleasurable mailing experience,” Dom Leca, CEO of Sparrow, said in a statement on the company’s website .
As expected, Microsoft reported a quarterly loss for the first time in its 26 years on the market on Thursday afternoon. The tech giant had warned previously that it would be taking a $6.19 billion write-down its 2007 acquisition of aQuantive, which Microsoft once hoped would help it break into the display market that continues to be dominated by Google.
The latest RFID market research from IDTechEx finds that in 2012 the value of the entire RFID market will be $7.46 billion, up from $6.37 billion in 2011. This includes tags, readers and software/services for RFID cards, labels, fobs and all other form factors. It includes passive and active RFID. Detailed forecasts are now available in the recently updated RFID Forecasts, Players and Opportunities 2012-2022 .
A revolutionary embedded algorithm in a new audio system from NXP Semiconductors N.V. boosts the output power of micro speakers by over 5 times, vastly improving the sound quality of mobile devices. By driving over 2.6 watts RMS into micro speakers that have previously been limited to 0.5 W, the NXP TFA9887 IC will give mobile phones, portable music players and tablets much louder sound, deeper bass, and higher sound quality – without risking speaker damage.
Building on its success of facilitating mobility initiatives for enterprise customers, Symantec Corp. today announced significant mobile portfolio updates to enable secure mobile email deployments, mobile application initiatives and Bring Your Own Device programs. With these updates, Symantec now offers the most comprehensive enterprise-grade platform with enhanced capabilities in device management, application management and threat protection.
The answer to better Wi-Fi security could lie on the surfaces of a wallpaper. A team of French researchers at Institut Polytechnique de Grenoble was able to develop a wallpaper that can allegedly block Wi-Fi signals. Working together with Centre Technique du Papier, the researchers claim that the wallpaper prevented Wi-Fi signals from being transmitted beyond the confines of an office or apartment.
