20090256285 | Method of producing a ceramic component - A method of producing a ceramic component includes dispersing an alpha-alumina nanopowder whose diameter is above 100 nm in water, using 2-phosphonobutane-1,2,4-tricarboxylic acid (PBTC) or 4,5-Dihydroxy-m-benzenedisulfonic Acid, Disodium Salt (Tiron™) as dispersant. The pH is shifted towards the isoelectric point (IEP) by adding a mixture of acetic anhydride and ethylene glycol or polyethylene glycol, drying in a controlled atmosphere (humidity, temperature) and post compacting using cold isostatic pressing and sintering the three-dimensional structure thus formed. | 10-15-2009 |

20100064195 | ENCODING AND DECODING A DATA SIGNAL AS A FUNCTION OF A CORRECTING CODE - The invention relates to correcting codes for encoding and decoding a data signal. A signal including data variables is coded into a signal including the data variables and parity variables. The encoding and decoding operations are based on a parity check matrix comprised of a systematic matrix and a parity matrix and having rows corresponding coefficients of parity equations and distributed into decoding windows of same size. In order to increase convergence of the iterative decoding, the elements of at least one column of the systematic matrix associated with a decoding window are “0s”, except for a single element which is a “1”. A data variable is only involved in one equation of the window and not involved in solving the equations of other windows as long as the solving of equations of the window is not achieved. | 03-11-2010 |
