Skilled workers vital to vibrant economy
According to a study by the National Association of Manufacturers, more than 80% of manufacturers report shortages of qualified workers.
Recognizing gear failures
Failure modes typically have distinct features. Here's what to look for.
High-power inverter starts chilly lamps
E220 Series dc-ac inverters from Endicott Research Group Inc., Endicott, N.Y., output 12 W at starting voltages to 2,300 Vrms for reliable cold-cathode fluorescent-lamp (CCFL) ignition at low temperatures.
Make plans now for Japan's Embedded Technology Conference 2007
The annual Embedded Technology Conference and Exhibition in Yokohama, Japan, runs Nov. 14 through 16.
Shaken, not blurred
A 3.1-megapixel system-on-chip camera for mobile phones incorporates antishake circuitry to eliminate blurred images, a first says Micron Technology Inc., Boise, Idaho.
Nanoscale MRI
IBM researchers have used MRI techniques to view nanoscale objects, a first and a major step toward microscopes able to image individual atoms in 3D.
LEDs illuminate DLP HDTVs
Phlatlight LED technology from Luminus Devices Inc., Woburn, Mass., goes in Digital Light Processing projection HDTVs with 1,080-pitch resolution, replacing arc lamps and color wheels.
Plug-in LEDs
What is said to be the world's first LED that runs directly from ac power comes from Seoul Semiconductor Co. Ltd. in Korea.
The heck with spec
Paint is about the only distinguishing feature of modern Indy race cars. That wasn't always the case.
3D solar cells
Conventional flat solar cells reflect a significant portion of the light striking them.
Let there be LEDs
