The last few years have seen the development of larger, higher power, higher luminescence light-emitting diode (LED) chips. Prior to this, LEDs were typically 0.020" x 0.020", came in various colors and were used primarily as optical indicators. This new breed of LEDs come in various colors, including white and UV, are typically 0.040" x 0.040" and are designed to provide high intensity light for illumination applications. Individually packaged versions of these LEDs are being used in arrays and clusters to replace standard incandescent and compact fluorescent light bulbs and are much more efficient at converting electrical power into usable optical power.

Starting Point for Overcoming Barrier to Fusion Power
Posted in Power Management, Energy, News on Thursday, 23 August 2012
The accuracy of a new model for predicting the size of a key barrier to fusion power, which was developed by physicist Robert Goldston of the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL), has been confirmed. Goldston’s model predicts the width of what physicists call the “scrape-off layer” in tokamaks, the most widely used fusion facilities.

Getting to the Heart of Tomorrow's Cardiovascular Technologies
Posted in Power Supplies, Electronics, Power Management, Medical, Features, MDB on Wednesday, 01 August 2012
Cardiovascular disease is the number one cause of death in the world. About 1.2 million Americans suffer from heart attacks every year. Approximately 2,000 Americans get heart transplants each year, but transplant hearts are in short supply, and many thousands of other advanced heart failure patients are left on the waiting list.

A Better Understanding of High-Temperature Superconductors
Posted in Power Management, Lasers & Laser Systems, Energy Storage, Energy, News on Friday, 22 June 2012
Superconductivity, in which electric current flows without resistance, promises huge energy savings – from low-voltage electric grids with no transmission losses, super-efficient motors and generators, and myriad other schemes. But such everyday applications still lie in the future, because conventional superconductivity in metals can’t do the job.
