HP predicts that "oval" LEDs will become the new standard for full-motion, full-color video signs, replacing the traditional cathode ray tubes used since the 1980s. Benefits of the LEDs, says HP: They last longer (70K+ hours), weigh less, are weather proof, and use up to 20% less power. HP designed its latest 5-mm LED lamps specifically for these full-color outdoor signs, as well as for single-color information signs. The lamps feature an oval-shaped radiation pattern (35 3 70 degrees) and high luminous intensity. They have smooth, matched radiation patterns that deliver consistent color mixing in full-color applications and message uniformity across the viewing angle of the sign. The lamps also use high-efficiency LED materials--aluminum indium gallium phosphide (AllnGaP) for amber and red, and indium gallium nitride (InGaN) for blue and green. Applications include outdoor displays such as advertising billboards and stadiums, and indoor displays like those in sports arenas, conference halls, and shopping malls. Hewlett-Packard.

In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
