I wonder if the dollar-store "shake lights" could be used as prior art?

You've missed the point - these are self-contained devices that produce reliable, although small, amounts of power from ambient vibrations. Sounds novel to me. -- Joe

Sounds novel to me. Self-winding watches have been around forever. At least to me the idea of harnessing sound random movement and converting it to electricity (rather than tightening up a spring) is an obvious extension. People have been working on such "micropower harvesters" for decades now...

You make the same mistake most do when considering the worth(lessness) of patents. You don't have the claims. Without the claims this is nothing more than a useless newsblurb to fill a just as useless trade rag.

How about the fact that all of the dollar store "shake lights" that I ever bought were "fake shake lights"? In my experience actually opening up 3 of these of 2 different brands, the movable slug was not magnetized, the leads of the coil were shorted together, and there was a battery consisting of (I forget which already) one or two lithium coin cells of some CR???? type. Maybe the prior art needs to be a non-dollar-store "shake light". - Don Klipstein (don(a)misty.com) |
