After reading the April 2010 example concerning Mazda overheating I realized this may be more of a problem than just with Mazda. I had exactly the same problem with my 2004 Explorer. It overheated twice with no warning until the gage was pegged out. The first incident was caused by a stuck thermostat and the second by a leaking thermostat housing hose. The engine had to be replaced after the second incident. The Explorer is the most heavily instrumented car I have ever owned, but the overheating warning system is stuck in the 60s when engines were slow to overheat and much more forgiving.
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.
