20140219306 | Multicolor Photonic Crystal Laser Array - A multicolor photonic crystal laser array comprises pixels of monolithically grown gain sections each with a different emission centre wavelength. As an example, two-dimensional surface-emitting photonic crystal lasers comprising broad gain-bandwidth III-nitride multiple quantum well axial heterostructures were fabricated using a novel top-down nanowire fabrication method. Single-mode lasing was obtained in the blue-violet spectral region with 60 nm of tuning (or 16% of the nominal centre wavelength) that was determined purely by the photonic crystal geometry. This approach can be extended to cover the entire visible spectrum. | 08-07-2014 |

20100026306 | METHOD AND APPARATUS FOR TELEMATICS-BASED VEHICLE NO-START PROGNOSIS - A system and method for determining the status of a vehicle battery to determine whether the battery may not have enough charge to start the vehicle. The method includes collecting data relating to the battery on the vehicle and collecting data relating to the battery at a remote back-office. Both the vehicle and the remote data center determine battery characteristics based on the collected data and the likelihood of a vehicle no-start condition, where the algorithm used at the remote back-office may be more sophisticated. The data collected at the remote back-office may include vehicle battery information transmitted wirelessly from the vehicle, and other information, such as temperature, battery reliability, miles that the vehicle has driven per day, ambient temperature, high content vehicle, etc. Both the vehicle and the remote back-office may determine the battery open circuit voltage. | 02-04-2010 |
20110144853 | MINING METHODOLOGY TO ELIMINATE INAPPROPRIATE SETTING OF ERROR CONDITIONS USING OPERATING PARAMETERS - A system and method for reducing or eliminating built-in tests and diagnostic trouble codes that are set as a result of improper parameter values. The method includes collecting field failure data that identifies diagnostic trouble codes and parameters of the system that are used to set diagnostic trouble codes. The method transforms the collected data into a format more appropriate for human analysis and pre-processes the transferred data to identify and remove information that could bias the human analysis. The method includes plotting linear and nonlinear combinations of operation parameters, performing data mining and analysis for detecting inappropriate settings of fault codes in the pre-processed data and providing the mined data to a subject matter expert for review to determine whether a diagnostic trouble code has been issued because of improper parameters. | 06-16-2011 |
20120303205 | DETECTING ANOMALIES IN FAULT CODE SETTINGS AND ENHANCING SERVICE DOCUMENTS USING ANALYTICAL SYMPTOMS - A method is provided for identifying a root cause of a fault in a serviced vehicle based on analytical symptoms. Parameter identification data associated with identified DTCs is retrieved. Parameter identification data from a plurality of vehicles experiencing the DTCs is collected. A first set of diagnostic rules is generated that identify vehicle operating parameters for executing a DTC algorithm or for triggering a DTC. A second set of diagnostic rules is generated that identify vehicle operating parameters used for selecting field failure data obtained when the DTC is triggered. Statistically significant rules are extracted from the second set of diagnostic rules. The first set of rules and the statistically significant rules are cooperatively applied to the parameter identification data for identifying a subset of the parameter identification data that represents anomalies. A subject matter expert analyzes the anomalies for identifying a root cause of the fault. | 11-29-2012 |

20080212677 | Efficient Video Block Mode Changes in Second Pass Video Coding - This disclosure describes techniques for second pass video coding in a multi-pass video coding scenario. The coding modes for some video blocks encoded during a second pass may be changed relative to the coding modes used for such video blocks in the first pass. However, motion information does not change for those video blocks that have the changed modes. In particular, mode changes can be made in the second coding pass relative to the modes used in the first coding pass without changing the manner in which motion information will be derived at the decoder, e.g., due to similarities between the original modes of the first pass and changed modes used in the second pass. The second pass coding techniques may also include quantization parameter adjustments, and the mode changes can cause such quantization parameter adjustments to have more profound refinements effects on the second pass coding. | 09-04-2008 |
20080273810 | VIDEO CODING MODE SELECTION USING ESTIMATED CODING COSTS - This disclosure describes techniques for coding mode selection using estimated coding costs. To provide high compression efficiency, for example, an encoding device may attempt to select a coding mode for coding blocks of pixels that codes the data of the blocks with high efficiency. To this end, the encoding device may perform coding mode selection based on estimates of coding cost for at least a portion of the possible modes. In accordance with the techniques described herein, the encoding device estimates the coding cost for the different modes without actually coding the blocks. In fact, in some aspects, the encoding module device may estimate the coding cost for the modes without quantizing the data of the block for each mode. In this manner, the coding cost estimation techniques of this disclosure reduce the amount of computationally intensive calculations needed to perform effective mode selection. | 11-06-2008 |
20100020886 | SCALABILITY TECHNIQUES BASED ON CONTENT INFORMATION - Apparatus and methods of using content information for encoding multimedia data are described. A method of processing multimedia data includes classifying content of multimedia data, and encoding the multimedia data in a first data group and in a second data group based on the content classification. The first and second groups are associated with quality levels. A user can request a target quality level. | 01-28-2010 |
