Patent CA-2330094-A1 (CA)
Title: Steam-assisted gravity drainage process
Inventor: ITO YOSHIAKI
IPC: E21B43/24
Filed: 2001-01-03
Abstract: Following second phase steam assisted gravity drainage operation using a co-operating pair of steam injection and fluid production wells, steam injection is terminated while flowing fluid production is continued, to draw down the reservoir pressure and flash steam in situ. Then a downhole pump is actuated to produce reservoir fluid and further reduce the reservoir pressure; thereby generating additional steam in situ. As a result of these steps, an additional recovery of oil is realized, using residual heat remaining in the reservoir at the end of steam injection and incremental steam generated in situ by pressure reduction obtained by pumping.

Title: Method and apparatus for performing packet loss or frame erasure concealment
Inventor: KAPILOW DAVID A
IPC: G10L21/02
Filed: 2000-04-19
Abstract: The invention concerns a method and apparatus for performing packet loss or Frame Erasure Concealment (FEC) for a speech coder that does not have a built-in or standard FEC process. A receiver with a decoder receives encoded frames of compressed speech information transmitted from an encoder. A lost frame detector at the receiver determines if an encoded frame has been lost or corrupted in transmission, or erased. If the encoded frame is not erased, the encoded frame is decoded by a decoder and a temporary memory is updated with the decoder's output. A predetermined delay period is applied and the audio frame is then output. If the lost frame detector determines that the encoded frame is erased, a FEC module applies a frame concealment process to the signal. The FEC processing produces natural sounding synthetic speech for the erased frames.

Title: System and method for maintaining the front of a fluid jet device in a relatively clean condition
Inventor: JACKSON PHILIP H
IPC: B41J2/165
Filed: 2001-05-29
Abstract: A purge/clean system and an associated method for A fluid jet apparatus, such as an ink jet printing system, having a fluid chamber including a chamber wall having an exterior surface and at least one orifice through which fluid is ejected from the fluid chamber toward a substrate involves a cavity defined adjacent the exterior surface of the chamber wall into which fluid which is, expelled from the at least one orifice during a purging or cleaning operation is permitted to flow and a vacuum pump for withdrawing fluid which is contained within the cavity. The cavity can be provided by a plurality of plate arranged in an assembled, or stacked, relationship against the exterior surface of the chamber wall and, with the aid of a fan or compressor, can be used to create a zone of above -atmospheric pressure adjacent the exterior surface of the printer head. With the zone of above-atmospheric pressure created within the cavity, any leakage of air from the region into the atmosphere effects a flow of air out of the region and thereby helps to maintain the at least one orifice in a relatively clean condition.

Title: Protocole de demande a repetition automatique
Inventor: ROOBOL CHRISTIAAN
IPC: H04W84/12
Filed: 1999-11-26
Abstract: Pendant une communication entre des premier et second noeuds de communication, le premier noeud reçoit une séquence d'unités de données transmises par le second noeud. Le premier noeud de communication détermine qu'une ou plusieurs des unités de données transmises soit n'a pas été reçue du tout, soit a été reçue de façon erronée (c'est-à-dire avec des erreurs). Une minuterie de retransmission est mise en route lorsque la demande de retransmission est envoyée. La minuterie de retransmission compte la durée du temps d'attente nécessaire à la demande de retransmission pour qu'elle atteigne le second noeud, pour que le second noeud retransmette les unités de données demandées, et pour que les unités de données retransmises atteignent le premier noeud. Lorsque la minuterie indique que la durée du temps d'attente s'est produite ou a expiré, un compteur est mis en marche. Sur la base de la valeur du compteur on peut déterminer si toutes les unités de données demandées à retransmettre ont été reçues correctement. Si la détermination indique qu'une ou plusieurs unités de données demandées ont été retransmises et reçues correctement, aucune action n'est entreprise. En revanche, si une ou plusieurs unités de données demandées à retransmettre ne sont pas reçues ou sont reçues de façon erronée, la procédure ci-dessus décrite est répétée.
