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)

MOSFET Pre-Driver IC Provides Fault Management

May 1, 2009 6:27 am | Product Releases | Comments

Designed for applications with high-power inductive loads, Allegro’s A4940 full-bridge MOSFET pre-driver IC incorporates fault diagnostics and reporting functionality. With an operating voltage from 5.5 V to 50.0 V, the 24-pin TSSOP-packaged device has a bootstrap charge management system that ensures the bootstrap capacitor is always sufficiently charged to supply the high-side gate drive circuit.

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.

Apple to Develop IC Design Capability

April 30, 2009 7:11 am | News | Comments

Apple Inc is hiring new employees from the semiconductor industry and is building the capability to design its own chips, the Wall Street Journal reported on Wednesday. The iPhone and iPod maker hopes its efforts will lead to new features for its devices and enable it to share fewer details about it plans with outside chip vendors, the report said, citing people familiar with Apple's plans.

Sensor Zone May 2009

April 30, 2009 5:45 am | by Steve Tomko and Helge Hornis, Ph.D, Pepperl+Fuchs | Articles | Comments

Automated Storage and Retrieval Systems (ASRS) are at the heart of any fully automated warehousing system. As in all automated solutions, users demand nearly perfect, (i.e., 100%) availability and exceptionally fast operation at the lowest possible price point. While the raw speed of an ASRS along each axis of motion is limited by the selected drives’ components, modern sensor technology

Configurable VCXO Operates From 0.75 MHz to 1.0 GHz

April 30, 2009 5:21 am | Product Releases | Comments

Provided in a 5 mm x 3.2 mm package, the XpressO FVXO-LC52 LVDS VCXO from Fox has an operating frequency range from 0.75 MHz through 1.0 GHz. The configurable-frequency device uses a third-order Delta Sigma Modulator to reduce noise levels comparable to traditional bulk-quartz and SAW oscillators.

Honda and Nissan Consider Plug-in Hybrids

April 30, 2009 5:03 am | News | Comments

Since their introduction in the US in late 1999, hybrid cars have been repeatedly dismissed as a “bridge technology”—a euphemism for a short-lived second-rate technology that briefly serves a purpose until it can be replaced with something better and longer lasting. But in recent statements coming within days of one another, executives from Honda and Nissan are reconsidering the role that hybrids will play in the coming decades.
