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.

A next-generation guided ammunition system for intercepting enemy fire that Lockheed Martin is developing for the Army has hit its targets in an initial series of tests by the company.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
