Energizer Stays One Step Ahead by Catering to Diminutive Device Trend by Jason Lomberg, Technical Editor “Quad A” may soon become part of the common vernacular. Although the AAAA battery (or Quad A) has been commercially available since 1989, it’s mostly been a niche product, difficult to find on shelves. But with consumer electronics moving towards […]

There are many reasons technology companies are stepping up efforts to make their products more efficient and environmentally friendly. Those reasons range from actual concerns about the environment to saving money and presenting a positive company image. Whatever the reason this is a hot topic and our sister publication Wireless Week recently ran an article describing […]

OLED technology has been around for a while and appears to offer significant power efficiency gains in slimmer packages. At this point, cost and operational lifetime constraints have kept the technology from becoming a reasonable option for most consumer applications. However, GE Global Research announced the successful demonstration of “roll-to-roll” manufactured OLEDs. The company claims that this process is […]

Energy News: Researchers found bacteria that can transform light into chemical energy — a method of photosynthesis still not completely understood by science, but which could become an energy windfall if it’s duplicatable by industry. The discovery happened at the famed Yellowstone National Park. The bacterium has “light-harvesting antennae known as chlorosomes, which contain about […]

Productive Product: Texas Instruments announced a line of floating point digital signal controllers. The TMS320F2833x devices provide 300 million FLOPS at 150 MHz at costs typically associated with fixed point processors, which means developers can accomplish more tasks using fewer chips, and thereby consume less energy. Software development is also simplified. Technology from solar power […]
