20120244011 | Turbocharger Brake - Exhaust gases can bypass a turbocharger to reduce its speed, but energy in the gases is then lost. A brake for a turbocharger can be implemented using at least one rotor driven by the turbocharger rotatable shaft and at least one stator. Either the rotor or stator are magnetic, the other being ferrous, such that rotation of the shaft induces eddy currents in the ferrous part, thereby extracting energy from the shaft. The magnetic field experienced by the ferrous part can be adjusted in response to an input parameter to control the level of braking. | 09-27-2012 |
20140205426 | MULTIPLE TURBOCHARGER CONTROL - A turbocharger system comprises: a gas input for receiving exhaust gases from an engine; a first turbocharger comprising a first compressor driven by a first turbine, arranged to be driven by received exhaust gases and providing a compressed air output defining a boost pressure a second turbocharger, arranged to be driven by exhaust gases passing through the first turbocharger or exhaust gases received at the gas input and being coupled to an electrical generator operative to provide electrical power, the first turbine not being coupled to an electrical generator; and a controller. A diversion mechanism may be configured to affect the flow of exhaust gases between the gas input and the first turbocharger. The controller may be configured to adjust the operation of the electrical generator independently from the operating mode of the associated engine, to affect the boost pressure. | 07-24-2014 |

20100106808 | REPLICA PLACEMENT IN A DISTRIBUTED STORAGE SYSTEM - Replica placement in a network of nodes is provided. Nodes are selected for replica placement to satisfy location-based preferences. Additionally, nodes are selected for replica placement to spread replicas of the same data over different fault domains and upgrade domains. In some instances, nodes may be selected for replica placement based on load-based information for the nodes. | 04-29-2010 |
20120060072 | ERASURE CODING IMMUTABLE DATA - Embodiments of the present invention relate to systems, methods and computer storage media for erasure coding data in a distributed computing environment. A sealed extent is identified that is comprised of two or more data blocks and two or more index blocks. The sealed extent is optimized for erasure coding by grouping the two or more data blocks within the optimized sealed extent together and grouping the two or more index blocks within the optimized sealed extent together. The optimized extent may also be erasure coded, which includes creating data fragments and coding fragments. The data fragments and the coding fragments may also be stored in the distributed computing environment. Additional embodiments include monitoring statistical information to determine if replication, erasure coding or a hybrid storage plan should be utilized. | 03-08-2012 |

20090125275 | Method For Determining Temporal Solar Irradiance Values - A method for generating temporal solar irradiance values for a selected area. Binary format hillshade files are generated for selected azimuth and altitude points on the Sun's path for selected time points for the area. Data in the hillshade files is reclassified into reclassified files, on basis of the selected time points relative to the solar radiation data. The reclassified files are then summed to generate a set of normalized reclassified files, each representing a selected intermediate interval. The values for each corresponding one of the cells in the set of normalized reclassified files are summed to generate an irradiance-weighted shade file. The hillshade files are summed by inclusively OR-ing corresponding values for each of the cells in each of the hillshade files to generate respective composite files for each said selected intermediate interval. The composite files are then summed to generate a summed shade/time frequency file in which each data point therein represents the frequency of repetition of corresponding cells in the hillshade files over a selected upper interval of time. Each data point value in the irradiance-weighted shade file is then divided by the corresponding data point value in the frequency file to generate a file having solar access values for the upper interval, relative to the intermediate interval, for the selected area. | 05-14-2009 |
