OneLED - Waterproof LEDs advance design of outdoor displays Design How-To 3/30/2012 1 comment Small multi-color LEDs with high brightness performance are ideal candidates for outdoor video displays with high resolution. This article will discuss the benefits of surface-mount LEDs which are made from a completely black package for highest contrast indoor video, as well as ingress protected (IP) LEDs for outdoor use.
High-voltage surge stoppers ensure reliability during power spikes Design How-To 3/29/2012 6 comments In automotive, industrial, and avionic applications, high-voltage power supply spikes are commonly encountered. The electronics within these systems must not only survive surges, but in many cases also operate reliably throughout the event—and devices charged via automobile power points (lighters) must also be protected.

(Cambridge, England), a spin-off from the University of Cambridge chartered with producing printed plastic solar cells, has announced it has commissioned a development and roll-to-roll printing facility at its headquarters.
Sharp offers more efficiency, luminous flux for Pico Zenigata LED line Product News 3/20/2012 Post a comment Sharp rounds off its Pico Zenigata LED portfolio with a new white high-performance LED series while increasing the luminous flux of the previous generation in parallel. The line-up now comprises three different series that shine with luminous flux levels of up to 72.5 lumens and with an efficiency of up to 125 lm/W.
Optoelectronics industry seeks manufacturing comeback News & Analysis 3/19/2012 1 comment Alarmed by the exodus of its manufacturing base to Asia, key players in the photonics industry are seeking to revive domestic manufacturing. The rewards? More U.S. manufacturing jobs and ability to provide greater amounts of secure bandwidth.
FlexRay spec rev offers back compatibility, lower costs Design How-To 3/15/2012 Post a comment The FlexRay electrical physical layer spec Rev. 3.0.1 has been released and production of second generation transceivers has started. Semiconductor manufacturers have to ensure full device specific functional range in existing applications with a drop-in replacement.
We teardown a Chevy Volt (exclusive videos) Design How-To 3/12/2012 2 comments What makes a Chevy Volt tick (and whirr and hum) is revealed in these videos where the car was taken apart over three days—quality, ruggedness, and modularity for incorporating future technology are apparent.
ISO 26262 cuts electronics complexity risks: Pt. 2- Design for robustness Design How-To 3/2/2012 Post a comment Future development and integration of automotive safety functions will strengthen the need to have safe system development processes and to provide evidence that all reasonable safety objectives are satisfied. ISO 26262 provides guidance to reduce these risks to a tolerable level by providing feasible requirements and processes.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
