20120154527 | Method and System for Frame Rate Conversion of 3D Frames - A 3-dimensional (3D) video rendering device may convert a first left view video of a decompressed 3D video having a first frame rate to generate a second left view video having a second frame rate, and convert a first right view video having the first frame rate to generate a second right view video having the second frame rate. The second left view video having a particular pixel resolution may be converted by the 3D video rendering device to generate a third left view video having full pixel resolution of the decompressed 3D video. The second right view video having the particular pixel resolution may be converted to generate a third right view video having the full pixel resolution. The 3D video rendering device may generate a sequence of video frames for 3D video display based on the third left view video and the third right view video. | 06-21-2012 |

20080235234 | ACCESS CONTROL LIST (ACL) BINDING IN A DATA PROCESSING SYSTEM - Systems for updating an access control list (ACL) associated with one or more resources in a data processing system are provided. The system provides a table including a list of one or more first ACLs that map to a corresponding one or more previously computed second ACLs. The system also updates a current ACL associated with a first resource of the one or more resources in the data processing system including determining whether one of the one or more first ACLs in the table matches the current ACL associated with the first resource. If one of the one or more first ACLs in the table matches the current ACL associated with the first resource then updating the current ACL associated with the first resource by associating the corresponding second ACL with the first resource. | 09-25-2008 |

20080296105 | Tension control system for a web of material - A tension control assembly including a rotating member, a braking member, at least one brake pad, a means for driving the at least one brake pad against the braking member, and a temperature sensing means. The braking member is attached to the rotating member. The at least one brake pad is positioned adjacent to the braking member. The means for driving the at least one brake pad against the braking member forces frictional contact between the at least one brake pad and the braking member, thus providing torque to the rotating member. The temperature sensing means measures the temperature of the at least one brake pad. | 12-04-2008 |

20090185752 | METHOD AND APPARATUS FOR CROPPING IMAGES - The boundaries of a scanned digital document are determined by identifying the largest connected component in the received digital document and assigning the boundaries of the largest connected component as the boundaries of the received digital document or by using a row by row and column by column analysis of the received digital document to identify horizontal and vertical bands in the digital image having pixels with a value opposite to the value of pixels of a background of the received digital document and assigning the horizontal and vertical bands to be the boundaries of the received digital document. These processes may be performed in series or parallel by a processor associated with a scanner that creates the digital document. | 07-23-2009 |

20140029067 | PORTABLE DOCUMENT SCANNER HAVING USER INTERFACE AND INTEGRATED COMMUNICATION MEANS - A portable document scanner (PDS) is provided that need not be in communication with a local computer. The PDS includes an image scanner for scanning an input document to generate a scan image, a processor, a wireless communications port that enables wireless communications with remote computing services, and a memory that stores instructions for execution by the processor to locally process the scan image. Such processing includes, for example, extracting identity, position, and/or orientation of one or more optical semaphores from the scan image, where the extracted semaphores include (1) optical characters including letters, numerals, and/or punctuation, (2) informational indicia including bar codes, data graphs, pictures, and/or icons, and (3) document formatting indicators including lines, bars, arrows, and/or grids. The extracted semaphore data is communicated to a remote computing service via the wireless communications port. The processing operations may be managed by the user through an integrated display interface. | 01-30-2014 |
