OSRAM Opto
Semiconductors have developed a pre-production green LED based on the OSTAR
platform that is twice as bright as its predecessors and has a luminous surface
that is uniform. The single-chip LED benefits from a green phosphor converter.
Initial samples are available, and OSRAM is currently
working with partners to develop appropriate LED data projectors such as those
used in the office and education markets. OSRAM Opto Semiconductors expects the LED to be widely available to projector
manufacturers in the summer of 2011.
The prototype with a single chip achieves 410 lm and emits at a
wavelength of 553 nm. Since a greater proportion of green than red or blue is
needed in a projector to produce white light, the increase in the brightness of
the green LED has a significant effect
on the overall system brightness. With these new LED prototypes, it is possible
to produce systems that deliver an overall brightness of 2,000 lm which is
required for office and education applications. LED projectors will soon be
powerful enough for screen sizes of more than two meters diagonal. Until now, such
applications have only been possible with projectors that use conventional
light sources such as high-intensity discharge lamps.
A new battery design, which replaces lithium with abundant and low-cost elemental sulfur, is still in its nascent stages but shows real promise for giving batteries more energy potential.
PTC will offer a virtual desktop environment for its Creo product design applications, potentially freeing engineers to run them from remote desktops on a variety of operating systems and mobile devices.
The push to achieving more intelligent, integrated manufacturing is putting a strong focus on networking and connectivity as key enabling technologies.
Now that solar and wind harvesting technologies are a thriving market, researchers are seeking other environmentally related energy sources for which they can create harvesting devices.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
