re: What were they thinking: heated glasses

I've always thought of my ears as heat sinks. Even in moderately cool temperatures, they can easily get painfully cold. I suspect they are thermally connected to specific areas of my brain and over cool those areas. Given that, I would welcome an ear heater. Perhaps they could even add some improvements such as a heat pipe people like me can stick in their ear. On the other hand, I don't wear glasses, so never mind.

If you wear glasses as I do, there are times when having heated eyewear would indeed be useful. In winter time, your classes can get very cold and instantly fog when they encounter warm moist air. Depending upon what you are doing, this could introduce a element of confusion that could have serious consequences. So I would not laugh too hard at this one, it actually addresses a need, albeit a low probability one. Just my opinion.

Yes, I had thought of that as a use for this invention, except they did not mention that. They did talk about melting ice and snow from the glasses!

Indeed, the invention might have its use case. In cold climates, the heating element in the lens frame (crucially important components not shown in the excerpt) will supposedly keep the glasses from fogging up. My issue is that item 28. What's it for? What signal is the "amplifier" amplifying? Presumably the cell 24 is providing the bias voltage for the op-amp, but to what end? Anyone?

More proof that you can get a patent for just about anything.

Well stated - there's nothing more annoying than heading outside to get the mail in the morning, and having to wait 60 seconds for the eye glasses to clear up so you can see where you're walking when you come back into your house. Or, if you store your sunglasses in your cold car, the moment you put them on to back out of the driveway, instant fog. It takes a good 30-60 seconds for the heat from your head to clear up the lenses when you're wearing contacts and want to wear sunglasses. The application is long overdue in my opinion. Likely, only those with expendable income might be able to afford these. Electronics comes at a cost as we all know. ; )

I just presumed the person thought a power amplifier could make the power from the battery more powerful! No connection is provided to the supply rails - oops.

Yes - the patent office is not require to ensure the patent is plausible - only novel and non-obvious.

I could definitely see a need to be able to heat the lens, or de-fog it in some other way. The frames, on the other hand, I don't really see the need to heat.

Anyone who tries to ski (or clear a snowy driveway) while wearing glasses and a ski mask quickly discovers the problem of fogging glasses. A working glasses heater would indeed be very helpful. If the patent has errors, that is no big deal; it is easy enough for a manufacturer to correctly connect the power wires.

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.
