20090016626 | JOINT CODING OF MULTIPLE TRANSFORM BLOCKS WITH REDUCED NUMBER OF COEFFICIENTS - A system and method for video/image encoding and decoding, where transform coefficients associated with a plurality of blocks are reorganized and coded together. Various embodiments perform transform and quantization and generate transform coefficients, where the coefficients of the transform blocks are reorganized and interleaved. Additionally, an encoding process involves coding only a subset of the transform coefficients belonging to the transform blocks resulting in one or more transform blocks less than the original number of transform blocks, and putting this into a bitstream. A decoding process involves decoding the one or more resulting transform blocks including the subset of transform coefficients from the bistream, the transform coefficients being put in an array and decoded. The decoder de-interleaves the decoded transform coefficients and any remaining coefficients of the one or more transform blocks are filled in according to a plurality of different methods. After the one or more transform blocks are fully decoded, inverse transform and inverse quantization are performed and residual data is generated. | 01-15-2009 |
20120128074 | VIDEO CODING USING SPATIALLY VARYING TRANSFORM - Transform coding is not restricted inside normal block boundary but is adjusted to the characteristics of the prediction error. Thereby it is possible to achieve a coding efficiency improvement by selecting and coding the best portion of the prediction error in terms of rate distortion tradeoff. | 05-24-2012 |

20130044240 | APPARATUS AND METHOD FOR GENERATING IMAGE DATA - Apparatus comprises at least one processor; at least one memory having computer-readable code stored thereon; a first camera module configured to provide first image data representative of a first image; and a second camera module configured to provide second image data representative of a second image. The first and second camera modules are arranged either side of an axis about which the first camera module is rotatable relative to the second camera module, and are arranged such that, when the first camera module is rotated relative to the second camera module by less than a threshold angle, a region of the first image overlaps a region of the second image. The computer-readable code, when executed by the at least one processor, causes the at least one processor to process the first image data and the second image data; and to generate third image data representative of a third image, the third image representing at least corresponding portions of the overlapping regions of the first and second images. | 02-21-2013 |

20130340092 | SOFTWARE LICENCE CONTROL - A system for software license control is described that is particular useful for use in a virtualized system, such as a cloud computing system. A module can be made available for use within the virtualized network, wherein a license fee is payable for use of the module. The module includes a license file that can be located wherever it is required. In addition, a central license file is provided at an administration node. The central license file is configured such that it can only be operated from that administration node, thereby preventing the copying of that file. The license file operating in the virtual network communicates with the central license file. The central license file controls the use of the licensed module. | 12-19-2013 |

20110159342 | ANODE AND A METHOD OF MANUFACTURING AN ANODE - The printed battery has cathode and anode electrodes with terminals to connect to an external circuit, separator therebetween and electrolyte. An anode electrode material is applied on one side of the separator and a cathode electrode material on the opposite side. The anode material is dry and hydrophobic and is prepared by providing an anode active material, conductive material, solvent and a binder that are mixed to form an anode ink. The anode ink is applied on a substrate and then dried. In response to the drying, the solvent evaporates and the anode ink forms a film on the substrate. The prepared anode material is applied on the separator. An electrolyte solution is printed on the separator that has the anode material thereon. A cathode material is applied between a collector material and separator. | 06-30-2011 |
