Teledyne's new ALPHALIGHT(TM) bright 6500K white LED backlight offers "shadow-free" uniformity for non-emissive displays such as active matrix liquid crystal. The light produces a uniformity of 1.3:1 over the exit aperture, while the light produced exhibits an optical gain of up to 100% through beam collimation. This new light uses only white LEDs and is not derived from mixing red, green, and blue LEDs as are some other white lights. ALPHALIGHT uses low-voltage (3.6 to 15V) dc power, operates with constant current or a pulse-width-modulated drive, has 20 ns rise times, and is infinitely adjustable with respect to dimming. Dr. David Pelka, director of product development at Teledyne, says the light can operate instantly without ac noise, and requires no warm-up or over-voltage start-up when addressed.

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.
