Title: Generating topic-specific language models
Inventor: HOUGHTON DAVID F
IPC: G10L15/18
Filed: 2010-06-30
Abstract: Speech recognition may be improved by generating and using a topic specific language model. A topic specific language model may be created by performing an initial pass on an audio signal using a generic or basis language model. A speech recognition device may then determine topics relating to the audio signal based on the words identified in the initial pass and retrieve a corpus of text relating to those topics. Using the retrieved corpus of text, the speech recognition device may create a topic specific language model. In one example, the speech recognition device may adapt or otherwise modify the generic language model based on the retrieved corpus of text.

Title: Systeme pour injection pulsee de fluide dans un trou de forage
Inventor: PRINGLE RONALD E
IPC: E21B33/068
Filed: 2009-01-19
Abstract: Selon l'invention, l'application d'impulsions à un liquide qui est injecté dans des puits rend la formation sol/liquide plus homogène et plus pénétrante. À cet effet, l'invention porte sur un système pour créer automatiquement les impulsions, dans lequel système un piston est actionné par un différentiel de pression (PDAF) entre la pression d'accumulateur délivrée et la pression de formation. Les niveaux de changement du différentiel de pression lorsque la vanne à impulsions s'ouvre (et que le différentiel de pression chute) et lorsque la vanne à impulsions se ferme (et que le différentiel de pression s'élève) sont exploités pour actionner un inhibiteur qui restreint le mouvement de la vanne et du piston, et qui retarde l'ouverture et/ou la fermeture de la vanne à impulsions. La vanne à impulsions est construite de façon à s'ouvrir de façon explosive, et de façon à créer ainsi des ondes de porosité pénétrantes dans la formation. Le système comprend un accumulateur de gaz comprimé, et un clapet anti-retour d'injection qui maintient une pulsation même lorsque le sol n'est pas saturé, et l'injecteur statique qui permet une injection non pulsée uniquement lorsque le sol n'est pas saturé.

IPC: G06F21/00
Filed: 2009-06-12
Abstract: The present invention extends to methods, systems, and computer program products for protected mode scheduling of operations. Protected mode (e.g., user mode) scheduling can facilitate the development of programming frameworks that better reflect the requirements of the workloads through the use of workload-specific execution abstractions. In addition, the ability to define scheduling policies tuned to the characteristics of the hardware resources available and the workload requirements has the potential of better system scaling characteristics. Further, protected mode scheduling decentralizes the scheduling responsibility by moving significant portions of scheduling functionality from supervisor mode (e.g., kernel mode) to an application.

Title: Adiabatic reactor to produce olefins
Inventor: SUNDARAM KANDASAMY MEENAKSHI
IPC: B01J19/24
Filed: 2010-01-21
Abstract: Processes for production of olefins from hydrocarbon feedstocks are provided. In one aspect, the processes of the present invention utilize coils passing through a pyrolysis furnace to partially convert a hydrocarbon feedstock to olefins, followed by further conversion of the hydrocarbon feedstock in an adiabatic reactor. A portion of the coils in the pyrolysis fur-nace carry the hydrocarbon feedstock and the remainder carry steam only.  After a selected period of time, the material flowing through the coils is switched. By flowing steam through the coils that had previously contained the hydrocarbon feedstock, on-line decoking can occur. In another aspect, a high temperature reactor is used to convert methane or natural gas to olefins.
