  How are you going to lead in 2016?   Leadership is often overlooked in the engineering discipline. We’re trained in how to think and how to creatively attack problems, but not so much in how to steer our companies in bold new directions. Late last year, I attended the first ever Innovation Summit at

Thinking outside the [box] College has changed a lot since I was a student. Shortly after I graduated from Georgia Tech, the campus underwent quite the building boom, thanks to its upcoming status as the Olympic Village for the 1996 Summer Olympic Games. Touring the school in the subsequent years always left me amazed at

Power & Energy Efficiency Handbook

The energy efficiency scam by Leland Teschler, Executive Editor Dan Carnovale sounds extremely pissed off. He says he has three gizmos on his work bench right now that are all marketed as devices that can be hooked onto power lines to save energy. And, he claims, “All of them are garbage.” Carnovale manages the Eaton

Motion Systems Applications Digital Issue – Aerospace: Showcasing motion excellence

NASA engineers and scientists saw years of design work come to fruition when the Mars rover Curiosity, a 2,000-lb feat of excellence, settled onto the red planet in a gentle touchdown of glory. But it wasn’t just the efforts of NASA personnel that gave humanity that moment—and every other win in the thousand-plus days that

The robots are free! One of the trends that’s been apparent at the last few industrial trade shows I’ve attended is that industrial robots are being unleashed from their metal prisons. It wasn’t long ago that the only examples of robots that you’d see—whether on the show floor or on an actual manufacturing plant floor—were

The craziness of our future energy prospects I’ve had the privilege of seeing analyst Peter Zeihan speak several times, and his discussion, “Geopolitical Analysis of Global Economics and Energy,” at the recent Industry and Economic Outlook Conference held by the National Fluid Power Association in Chicago was truly fascinating. Zeihan feels that the U.S. is

What manufacturing can learn from Thailand Earlier this year, I was part of a journalist delegation to Thailand, the Southeast Asian country that’s probably known more for tourism than industrial engineering prowess. But after a week of touring manufacturing facilities that included such international heavyweights as Caterpillar and Nissan, I left with a new mindset

2015 Motion Systems Handbook

Happy Five-Year Anniversary, Motion Handbook Welcome to the fifth edition of Design World’s annual motion control compendium. Observant readers will notice a slight change to this year’s handbook. In years past, it was called the Motion Control Handbook. This year we’ve changed the name to the Motion Systems Handbook. Why the change? For one, we

Test & Measurement August 2015 Handbook

No nostalgia for old test instruments The media constantly reminds us that the capabilities we can get in our laptop computers and PCs have grown exponentially over the past few decades. Though it has gotten much less press, the same phenomenon applies to electronic test instruments. For evidence, consider the Heathkit Model 10-4205 oscilloscope I
