@EbB_VT: Oh, I don't have that issue viewing with PowerPoint. But I just viewed it with LibreOffice and I see what you are talking about. LibreOffice doesn't implement any of the contrast differences. All background images are full on and interfere with the slide text.
@Fred Eady: It appears that the background feature you've used in todays deck is not compatible with non MS PowerPoint viewers.
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.
