Note:  There is a gap in the US Patent coverage.  I have decided it is important to be as current as possible. So I will first cover the most recent patents and, then, go back to the earlier patents as time permits.  I am now 27 weeks behind so it will take some time to catch up.  Sorry about that.  (RDC 9/13/2011)
