ICP Electronics has released a PICMG single board computer with Intel PCI-Express architecture, the Rocky-6161. The PCI-Express is the latest I/O interface to replace PCI for higher bandwidth and has become a new standard for the next-generation computer industry.
Designed for emerging solid-state lighting uses, where ultra-bright illumination and a versatile colour range is desired in a reflow solderable design optimised for proper thermal management, BivarOpto has introduced a 3 W LED module.
While the degree of precision and reproduction accuracy are unable to match those of costly digital systems, there are many applications that do not require this performance level
A high-capacity chip under development is claimed to have the potential to do away with many of the identity documents, credit cards and passwords people have to use each day. The IST program-funded project SM-PAYSOC has created a working prototype of the chip packaged in a smartcard, which in the future could also be incorporated into a USB token or a SIM card.
The Optosign range of Aztec LED Light Engines combine the brightest LED arrays available, with manufacturing and technological expertise, to create stylish products that offer a viable alternative to traditional light sources in a variety of applications.
A team of University of California scientists at Los Alamos National Laboratory have developed what it claims is the first inorganic, multi-colour light-emitting diodes based on colloidal quantum dots encapsulated in a gallium nitride semiconductor.
Russell Dupuis talks about the development and future of this revolutionary technology in conversation with Jane Sanders
LEDs in arrays need constant current driving - for consistent driving current through each LED. Putting a resistor across each LED will not ensure the current through each LED in the array will be the same because every LED has its own voltage drop value.
Researchers at the University of Pennsylvania propose to shrink circuits to save space and power and, more importantly, accommodate electronic applications at much higher frequencies than are possible with current models - applications that include nano-optics, optical information storage and molecular signalling.
Designed for single phase compressors of up to 6.5kWatts (6.5 shaft horsepower), i-Start's patented switching technology not only reduces start-up currents to less than 45Amps, it reduces electrical load and hence wear on the starter as well, offering the potential of longer life for both compressors and starters alike.
