No, it is just the opposite. The patent (which you can read online on USPTO) is written around the physical process...not the computational algorithms.
Now I understand all. Despite it is something physically.. or conceptually similar to making an IR.
But now, reading the patent, i think maybe is the only way to protect his product. Because it looks more simple than I though, so it is easier to copy aswell. Kemper is comparing to a reference profile, the mother of the profiles, not creating it from scratch.
So maybe the competence is already working on this technology, waiting for the expiration date. If someone crazy patented this idea in the 60's (lots of crazy patents just in case), then we maybe would be having ala'kempers devices everywhere, like an IR.
Sorry..crazy thoughts today.
