I agree, Chuck. Like many of the Sherlock Ohms blogs, it's hard to imagine how they figured out such an off-the-wall solution. It is certainly not intuitive. The trick here was remembering something odd from the past.
This is what I love about the Sherlock Ohms postings. You can turn the equipment upsidedown to find the problem, but in the end, it was a line that had to be drawn darker. This is a common solution to difficult problems -- look at what was difficult at an earlier stage in the equipment's development.
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 radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
