20120290591 | METHOD AND APPARATUS FOR ENABLING VIRTUAL TAGS - A method and apparatus for enabling virtual tags is described. The method may include receiving a first digital image data and virtual tag data to be associated with a real-world object in the first digital image data, wherein the first digital image data is captured by a first mobile device, and the virtual tag data includes metadata received from a user of the first mobile device. The method may also include generating a first digital signature from the first digital image data that describes the real-world object, and in response to the generation, inserting in substantially real-time the first digital signature into a searchable index of digital images. The method may also include storing, in a tag database, the virtual tag data and an association between the virtual tag data and the first digital signature inserted into the index of digital images. | 11-15-2012 |

20130325328 | AUTOMATIC CORRECTION OF TRAJECTORY DATA - Initial trajectory data that provides an initial description of an approximate trajectory of a device during a time period, and correction data that indicates a location of the device outside the approximate trajectory of the device within the time period, are received. A modified trajectory data that provides a modified description of a corrected trajectory of the device is generated. In particular, terms to express (i) location constraints that limit deformation of the approximate trajectory of the device and (ii) a modification constraint that limits departure of the corrected trajectory of the device from the location indicated by the correction data are generated, and the initial description of the approximate trajectory of the device is modified using the generated terms. | 12-05-2013 |

20100220173 | Estimation of Panoramic Camera Orientation Relative to a Vehicle Coordinate Frame - A system and method are presented for estimating the orientation of a panoramic camera mounted on a vehicle relative to the vehicle coordinate frame. An initial pose estimate of the vehicle is determined based on global positioning system data, inertial measurement unit data, and wheel odometry data of the vehicle. Image data from images captured by the camera is processed to obtain one or more tracks, each track including a sequence of matched feature points stemming from a same three-dimensional location. A correction parameter determined from the initial pose estimate and tracks can then be used to correct the orientations of the images captured by the camera. The correction parameter can be optimized by deriving a correction parameter for each of a multitude of distinct subsequences of one or more runs. Statistical analysis can be performed on the determined correction parameters to produce robust estimates. | 09-02-2010 |

20110317452 | BI-DIRECTIONAL POWER CONVERTER WITH REGULATED OUTPUT AND SOFT SWITCHING - A resonant, bi-directional, DC to DC voltage converter with loss-less (soft) switching having regulated output and capable of converting power between two, high-potential and low-potential DC voltage sources. The converter's semiconductor and magnetic components provide both, output regulation and soft switching in both (step-down and step-up) directions of power conversion which reduces total component count, cost and volume and enhances power conversion efficiency. | 12-29-2011 |

20080201390 | HIGH-AVAILABILITY AND DATA PROTECTION OF OLTP DATABASES - A method is for use with a primary online transactional processing (OLTP) database, to maintain a secondary storage usable by a backup OLTP database, wherein the primary storage, of the primary OLTP database, includes data files. In accordance with the method, as transaction indications for the primary OLTP database are recorded in at least one transaction log file, in the primary storage of the primary OLTP database, the transaction indications are caused to be mirrored to the secondary storage. At the file system level of the storage of the primary OLTP database and of the secondary storage, a state of data files of the primary OLTP database is occasionally caused to be duplicated from the primary storage to the secondary storage. | 08-21-2008 |
20080243949 | DIVIDED BACKUP OF DATA WAREHOUSE - A data warehouse characterized by a plurality of fact tables and at least one dimension table is backed up. For fact tables that are static, those fact tables are backed up using a first backup method that is, for example, optimized for static data. For example, the first backup method may be at the file system level, below the database level, and can be a very time and computationally efficient way to synchronize blocks of data. Thus, for example, the first method may be a method that is not “database-aware” and does not consider the database structure in its backup processing. For fact tables that are dynamic, those fact tables are backed up using a second backup method. For example, the second backup method may account for the dynamic nature of data in the portion being backed up by being, for example, “database aware.” In addition, the at least one dimension table is backed up. By treating the fact tables in this way for backup, the process of backing up a data warehouse can be made more efficient overall. | 10-02-2008 |
