I've noticed -- in my case with an automotive lighting junction box for the brake lights in a 1988 Toyota Camry -- that burned traces are not only from high current (although that's the usual cause), but can wear out over time. I'm not sure if that's from normal use or from slight periodic surges. Actually, in the case I'm talking about, it was more the connector pins which had problems, and they weren't corrosion based, but rather from current. YMMV.
Your wife has to give you big kudos for sleuthing out that fix. I have a pretty handy husband, but in my house, that would have been a $700 repair bill hit. It's nice to hear a fix-it story where engineering rigor and diligence not only took center stage, but paid off in spades.
In an age of globalization and rapid changes through scientific progress, two of our societies' (and economies') main concerns are to satisfy the needs and wishes of the individual and to save precious resources. Cloud computing caters to both of these.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
