It is actually gratifying to see that fuzzy logic is all buttons dead. Like Bob Pease, I recognized early on that it was all hype and no substance. Marketing is always looking for buzz words that make consumers think their new product is better. Fuzzy logic was nothing more than a fancy name for a collection of well known techniques, starting with piecewise linear interpolation, buried behind a fancy front end methodology! The problem is, that methodology hid the nature of what was actually going, deceiving the gullible that it was something new, and preventing them from actually analyzing the resulting equations and algorithm which might have allowed them to optimize them (assuming they were capable). Or to state it differently, our industry is always looking for a "magic bullet" that can make a mindless tech able to do what an engineer can do. Fuzzy logic was supposed to take both the math and thinking out of complex control systems. But once again it turns out that there is no successful substitute for a human who understands the problem, actually thinking about it--which is another point Bob Pease would have strongly agreed with, were he still part of our community.

I recall a camera advertising using fuzzy logic in their auto-focus system -- a marketing SNAFU.

I think that was the startup of which I was thinking. Who acquired them?

Thanks Brutus Good to know all that coverage of fuzzy logic back in the day helped with space exploration.

Look up Togai InfraLogic some time. Don't know how active they are at present.

According to some pubblications there are still lots of fuzzy-logic based applications. For example, the MASSIVE 3D animation system for generating crowds uses fuzzy logic for artificial intelligence. This program was used extensivly in the making of the Lord of the Rings trilogy as well as The Lion, The Witch and the Wardrobe films. More on http://www.calvin.edu/~pribeiro/othrlnks/Fuzzy/apps.htm

That line reads backwards? Shouldn't it be "electric pump controlled by fuzzy logic" Or is fuzzy logic alive and well and providing marketing services and a warm cosy feeling -- as in the fuzzy logic washing machine.

I have a modern home-use blood pressure measuring machine (don't ask) made by Omron in Germany. On page 11 of the instruction manual the is a line that reads. Inflation: Fuzzy-Logic controlled by electric pump. So in answer to your question Fuzzy-logic is alive and well saving lives.

I heard of fuzzy logic in high school in Romania when a professor from the local university came and gave an introductory class about it. It seemed so interesting and the guy was so convinced that this is the future. After that in my first year of undergrad was part of the (mandatory) Special Math class. The math behind it is interesting and elegant at least at level I studied it. It is fascinating how all this revolutionary ideas that were all the rage not long ago were completely forgotten: neural networks, chaos theory, fuzzy logic. This was supposed to be the future but we still do things the same as 50 years ago.

I'm currently reading a great book on Fuzzy Logic -- I'm still in the early part of the book, but I love all of the history and background -- I'll report back further when I finish the little scamp

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
