Researchers in Hong Kong claim to have developed the highest power efficiency non-doped white organic light emitting device (WOLED) made using a single white-emitting material. They believe that their high purity, color stable device, surpasses existing WOLEDs and is a more efficient and environmentally friendly alternative to inorganic LEDs.
Seoul Semiconductor, the eighth-largest LED manufacturer in the world, announced today worldwide release of an upgraded version of Acriche, the world's first semiconductor lighting source for AC power outlets in US, Europe and Asia. The new Acriche, package type emitting 200 lumens, is being provided as an emitter with features including higher brightness of 200 lumens at 3.3 Watt, which is nearly 60 lm/W or 50% brighter than the version released last November. Due to its advanced high-yield device fabrication methods and the economics of high capacity, Seoul Semiconductor is able to reduce the price of the enhanced version of Acriche by 40%, making it more competitively priced to penetrate the conventional lighting market.
It had to happen sooner or later. With all the attention being given to gleaming chrome wheels, someone would have to figure out a way to show them off at night.

Senators are planning to cut budgets for the space interceptor portion of the controversial US missile defence programme, according to reports. However, it appears that a complementary scheme to blast enemy ICBMs shortly after takeoff using a giant laser cannon mounted in a jumbo jet will be fully funded.
So when Democrats wanted to pass a bill to phase out old-style incandescent light bulbs and require that Americans replace them with more energy-efficient models, they turned to Alaska Sen. Ted Stevens for some GOP support.
The universe's earliest stars may hold clues to the nature of dark matter, the mysterious stuff that makes up most of the universe's matter but doesn't interact with light, cosmologists report.
Bookham, Inc., a leading provider of optical components, modules and subsystems, today announced that its OceanBrightTM submarine pump module has achieved full qualification. The product, which is used in erbium doped fiber amplifiers (EDFAs), has commenced volume shipments and is actively deployed in undersea cable systems around the world. It will be shown for the first time in Europe on the Bookham stand (number 17094) at ECOC 2007.
Unidym, Inc., a majority-owned subsidiary of Arrowhead Research Corporation, announced today that U.S. Patent No. 7,265,174 has been issued by the U.S. Patent and Trademark Office. With respect to transparent conductive films, Clemson University has exclusively licensed this patent to Unidym. Unidym is a leader in the development and manufacture of carbon nanotubes for applications in the electronics industry. Unidym, which recently merged with Carbon Nanotechnologies, Inc. (CNI), possesses a foundational patent portfolio that covers nearly every aspect of carbon nanotube manufacturing and processing.
Recent research shows that humans are surprisingly poor at matching a face in a photograph to that seen in real life. The situation is the same with automatic face recognition systems. In today’s surveillance society, correct photo identification is of the utmost importance and with the government’s proposed identity card scheme expected to begin in 200, the ID issue is highly controversial.
