Squeezable Ferroelectrics May Create Instant-On Memory

May 4, 2009 7:00 am | News | Comments

Low-power, high-efficiency electronic memory could be the long-term result of collaborative research led by Cornell materials scientist Darrell Schlom. The research, to be published April 17 in the journal Science (Vol. 324 No. 5925), involves taking a well-known oxide, strontium titanate, and depositing it on silicon in such a way that the silicon squeezes it into a special state called ferroelectric -- a result that could prove key to next-generation memory devices.

Parallel Shaft Gearmotors Deliver up to 500 in-lbs

May 4, 2009 6:44 am | Product Releases | Comments

Real-Time Data System Includes Multiband Transceiver

May 4, 2009 6:09 am | Product Releases | Comments

Provided in a 19" rackmount server chassis, the RTS 2701 Recording and Playback System from Pentek includes a Dual-channel multiband transceiver. The system is well suited for digitizing analog signals from a communications system or a radar system and delivering that data to high-speed disk arrays at sustained data rates as high as 500 MB/second.

Obama Seeks Tax Changes for U.S. Firms Overseas

May 4, 2009 5:42 am | by Kim Dixon, Caren Bohan, and Doina Chiacu | News | Comments

President Barack Obama on Monday will propose changing provisions in the tax code that he says encourage U.S. companies to move jobs overseas, as part of a broader package aimed at saving $210 billion over 10 years. U.S. officials said that in an announcement planned for 11:05 a.m. EDT, Obama will seek to follow through on a campaign promise to change the tax treatment of American firms with overseas operations.

Facebook Boosts Security After Dual Phishing Attacks

May 4, 2009 5:19 am | News | Comments

Facebook has brought in some soldiers to fight the war against malware and phishing scams on the social-networking site. After two different malware attacks this week, Facebook announced it would begin using San Francisco-based MarkMonitor's antifraud services as an additional layer of protection against attacks.

Trench MOSFETS Boast High Current Ratings

May 1, 2009 7:32 am | International Rectifier | Product Releases | Comments

Available in a variety of packaging including TO-220, D2PAK, TO-262, and 7-lead D2PAK, logic-level gate-drive trench HEXFET power MOSFETs from International Rectifier have a package current rating of up to 195 A.

MIT Creates Projector-Based Approach to Capture Motion

May 1, 2009 7:00 am | News | Comments

Researchers at MIT have developed a new system that may provide a cheaper and more efficient way to track motion. The system, called Second Skin, could be a cheaper alternative for creating special effects for movies.

Solid State Lighting Could Learn From Betamax

May 1, 2009 6:59 am | by by Jason Lomberg, Technical Editor | Blogs | Comments

Conventional wisdom says that “early adopters” eventually bring new technologies into the mainstream. Thus, the effort to promote solid state lighting (SSL) has ample historical precedence. Back in the late 70’s, 80’s, and 90’s an epic battle was waged between Video Home System (VHS) and Betamax (Beta). One can draw lessons from the eponymous “videotape format war”—specifically, why technologies catch on (while others fade away)

Motorola's Losses Continue

May 1, 2009 4:48 am | by PETER SVENSSON, AP Technology Writer | News | Comments

Motorola Inc. defeated low expectations Thursday, posting a smaller first-quarter loss than Wall Street had expected and regaining its position as the world's fourth-largest maker of cell phones. Investors were largely unimpressed, and analysts pointed to deterioration in the Motorola units that have been propping up the dismally performing cell phone operations.

Government Pushes for Faster Medical E-Record Deployment

May 1, 2009 4:35 am | by Susan Heavey | News | Comments

Electronic health records need a nudge from the government if the technology is to become widespread, the nation's new health information technology czar said on Thursday. "It is clear that this field has not advanced (enough) when left exclusively to the private sector so there is a public role," said Dr. David Blumenthal, head of the Department of Health and Human Services' Office of the National Coordinator for Health Information Technology.
