| 20110309779 | VEHICULAR ELECTRICAL SYSTEM AND METHOD FOR CONTROLLING AN INVERTER DURING MOTOR DECELERATION - Methods and systems for operating an inverter coupled to an electric motor are provided. The inverter has a plurality of high switches and a plurality of low switches coupled to the electric motor. An event indicative of deceleration of the electric motor is detected. The inverter is alternated between a first mode of operation and a second mode of operation during the deceleration of the electric motor. In the first mode of operation, each of the plurality of high switches is activated and each of the plurality of low switches is deactivated. In the second mode of operation, each of the plurality of low switches is activated and each of the plurality of high switches is deactivated. | 12-22-2011 |

| 20090184958 | UPDATING A MODEL OF A SUBTERRANEAN STRUCTURE USING DECOMPOSITION - To update a model of a subterranean structure, a partial decomposition is computed of an operator that is used to compute a parameterization representing the update of the model. The partial decomposition of the operator is selected from among a partial eigendecomposition of a Fisher information operator, and a singular vector decomposition of the operator. A term based on additional information is combined with the partial decomposition of the operator to derive an update of the model. | 07-23-2009 |
| 20090303834 | COMBINING GEOMECHANICAL VELOCITY MODELING AND TOMOGRAPHIC UPDATE FOR VELOCITY MODEL BUILDING - A method for updating a velocity model of a subsurface of the earth is described herein. A tomographic update to the velocity model of the subsurface may be performed to generate a tomographic velocity model update. A geomechanical velocity model update of the subsurface may be calculated. The geomechanical velocity model update may be combined with the tomographic velocity model update. | 12-10-2009 |
| 20110098996 | Sifting Models of a Subsurface Structure - Multiple models are generated based on information relating to uncertainties of model parameters, where the models are consistent with preexisting data regarding a subsurface structure. A system receives, on a continual basis, information collected as an operation is performed with respect to the subsurface structure. The multiple models are recursively sifted to progressively select smaller subsets of the models as the collected information is continually received. | 04-28-2011 |

| 20080235676 | Optimal Floating-Point Expression Translation Method Based on Pattern Matching - Embodiments of the present invention include code generation methods. In one embodiment, a table of patterns is generated. Each pattern in the table includes an FMA (fused multiply-add) DAG (Directed Acyclic Graph), a canonical form equivalent of the FMA DAG, and a shape corresponding to the canonical form equivalent. Incoming floating-point expressions are matched against the patterns in the table during compilation of a program to obtain optical sequences of FMA, FMS (fused multiply-subtract), and FNMA (fused negate multiply-add) instructions as compiled instructions for computing the floating point expressions. | 09-25-2008 |
| 20100275192 | Generating optimal instruction sequences for bitwise logical expressions - A sequence generator generates a table of optimal instruction sequences for all bitwise expression having a specific number of variables. An index generator generates a bit-string index that corresponds to a particular bitwise expression. The bit-string is generated from a truth table. A table lookup unit is coupled with the index generator. The table lookup unit finds an optimal instruction sequence for the bitwise expression from within the table of optimal instruction sequences based at least in part on the generated bit-string index. | 10-28-2010 |
