I have done a little search on US patent database. Please, can you
confirm that the number of your patent is 6,169,990?
I am a little bit surprised, it is not clear to me where is the novelty
in the techniques your patent claims. The implementation techniques I
have published in that e-mail are old, some very old ("prior art").
