Hi. I am not participating in the context, but I found that US 7843225 B2 could also be a known reference.

Hi Pedro. Thanks for the comment! Fortunately, US 7,843,225 cannot act as a known reference as it was first filed April 14th, 2009 which is after the date criteria of the contest (July 29th, 2002). Thanks for bringing this to our attention!
