LED - revolutionary backlighting for industry LCDs?
Light emitting diodes are used in an increasing number of medium- and large-format displays as backlight. As could be seen recently at the ifa, the Consumer Electronics sector is assuming a pioneering role here " all liquid crystal display manufacturers presented ultra-flat LCD TV appliances with LED backlighting. But is the new backlight technology also suitable for industrial applications?
Solving power outage challenges facing industrial touch screen display control panels
This article reviews the advantages of touch screen display control panel systems, discusses the challenges faced during power failures, and looks at a solution using a client/server architecture based on nvSRAM memories and software transaction logs.
Capacitive touch sensors - development tools that make the difference
Made popular by products like the Apple iPod adopting it, capacitive sensors have now become the popular choice as a replacement to mechanical buttons, switches and sliders.

Green Engineering: Rail maintenance system advances with digital embedded design
This article describes a Blackfin/LabVIEW-based rail-maintanance system that measures, locates and fixes rail defects while achieving the real-time behavior, cost-effectiveness and robustness required in that harsh environment.
The COTS Ecosystem--Strength in numbers
Getting one or two companies to work together is no small feat. Today, five diverse organizations make up the COTS Ecosystem. They're complementary, insist they don't compete, and they're making great strides in furthering the adoption of COTS. Here's a roundtable discussion with the members--designed to eliminate confusion and well, just see what they're all up to.

Open-Source Robotics and Process Control Circuit Examples - Part 3: Speed-controlled DC motor
See how to prototype a speed-controlled DC motor circuit - starting from basic principles - as the author of the "Open-Source Robotics and Process Control Cookbook" describes how he developed the circuit and coding for the main propulsion system of an autonomous submarine project.
Flexible I/O structure allows MCUs to have 'soft' I/O functions
As the cost of silicon continues to fall, today's microcontrollers have more and more functions integrated into every device. Today, a typical microcontroller (MCU) will probably have at least three 16-bit timers, with many channels of timer input and output, pulse-width modulation (PWM) outputs and a number of 8 bit timers. More and more functions are now moving to software to increase system flexibility and reduce cost. The next step in this evolution is to make the underlying hardware of the chip itself more flexible.
Using correct-by-construction techniques and tools to simplify board design
A "correct-by-construction" PCB layout methodology can help designers shorten their design cycles and avoid design iterations between the design and layout stages.
