Title: Apparatus and method for non-destructive inspection
Inventor: TANAKA SHOGO
IPC: G01N33/38
Filed: 2002-11-06

Granted: 2010-04-13
Abstract: La présente invention a pour objet un procédé intégré de traitement de l'eau et de désulfuration de gaz de carneau dans lequel un circuit d'eau contenant des minéraux à l'origine de la dureté est soumis à un traitement avec un agent de précipitation alcalin pour précipiter lesdits minéraux et produire un circuit d'eau plus douce. Par la suite, l'eau alcaline adoucie est dirigée vers une tour de lavage pour laver un gaz de carneau contenant du dioxyde de soufre de manière à produire un gaz pauvre en soufre. Ladite invention est particulièrement utile pour une opération de récupération de bitume basée sur la vapeur, pour laquelle le bitume, le gaz acide produit ou d'autres combustibles contenant du soufre sont brûlés pour produire la vapeur employée pour la récupération du bitume. De manière plus spécifique, l'eau produite associée au procédé de récupération de bitume est adoucie en vue de sa réutilisation comme agent de lavage d'un gaz de carneau à forte teneur en soufre en provenance des générateurs de vapeur. Ce procédé est avantageux sur le plan économique et réduit au minimum les exigences sur l'élimination des déchets.

Title: Method of finding orphan blocks in block based image compression schemes
Inventor: MYERS JAMES C
IPC: H04N7/26
Filed: 2004-01-14
Granted: 2009-08-18
Abstract: A method of processing the contents of an image which are digitized and formatted into macro blocks (MB) of information. The method involves flagging for further use those macro blocks whose contents satisfy a first criteria. Further processing of the method is performed only using the status of each macro block, either flagged or unflagged, and ignoring the contents. Unflagged blocks adjacent flagged blocks are investigated using a testing protocol and using a second criteria to determine if they should also be flagged. The status of an unflagged block meeting the second criteria is changed from unflagged ("O") to flagged ("1"). The method converts unflagged orphan macro blocks which should have been identified using the first criteria into flagged macro blocks. These are .combined with the original set of flagged macro blocks to determine the entire set of macro blocks whose contents are to be used in subsequent processing.
