Intermittent Problems
Tim   9/15/2011 8:09:51 PM
Intermittent problems are always the hardest to track down.  Multi wire cables with a random broken wire or connection have been my nemesis for years.

Intermittent shutdown problem

Coupling between power leads of any kind and sensor leads is always suspect, and this is a perfect example. The other cause would probably be traced to a difference in the components in the input circuit of the fuel flow meter. Small production variations that do not impair the apparent performance of one part of the system may still cause it to affect another part. 

Good detective work on finding the link that caused the problem, and good choice in changing the other units as well.

These cars were originally built in the 1970's by Rohr using Turbomeca gas turbines. Our company remanufactured them in the late 90's with updated engines and electronics. I don't believe Rohr is around any more, but Turbomeca still has engines in several GT rail applications around the world. They are an awesome little power plant for their size. They really shine for running an APU generator.

Absolutely!, Turbomeca produces excellent turbines, just look at the repowering of the Sikorski S-76 spirit helicoptes, which were marginal with their original engines by Allison, that surpassed all expectatives when they were re-equipped with Turbomeca Arriel 1S (and 1S1/2S2 versions in later models). Turbomeca engines are outstanding from both size/weight vs performance.  A happy engine makes a happier helicopter pilot!

The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
Researchers have developed a new flexible fabric that integrates both movement and sensors, introducing new potential for technology-embedded clothing and soft robots.
