| 20100069229 | Method For Synthesising A Nano-Product - A method for the synthesis of nano-products, such as atomic titanium oxide wires. The method allows wires of anatase titanium oxide wires to be formed in a range of tunable diameters and aspect ratios in the nanometer and subnanometer size scales. The method also allows the titanium wires to be capped by oleic acid to enhance dispersing and solubility. The method allows the titanium wires to be surface doped with nitrogen species to enhance stability and functionality such as enhanced absorption in the visible wavelength region, which is useful for photodegradation of organic wastes in water by sunlight. | 03-18-2010 |

| 20090317017 | IMAGE CHARACTERISTIC ORIENTED TONE MAPPING FOR HIGH DYNAMIC RANGE IMAGES - A method and system map high dynamic range images to low dynamic range images. An input set of luminance values can be divided into separate regions corresponding to particular luminance value ranges. A region value can be determined for each region. Based at least in part on the region value, a quantity of range assigned to each region for tone mapping can be dynamically adjusted until each region meets a decision criterion or stopping condition, referred to herein as “concentration.” A region can be said to be concentrated if all luminance values therein are within a concentration interval or range. After a region is concentrated, it can be tone-mapped by quantization. | 12-24-2009 |

| 20100174730 | Digital Resources Searching and Mining Through Collaborative Judgment and Dynamic Index Evolution - A method is disclosed for a search engine or part of a search engine which utilizes collective intelligence, evaluation, and judgment, including web intelligence, to create and adapt the content of a generalized index hierarchy for digital resources to be searched. Digital resources to be searched can be stored and managed as a localized or distributed repository of images, video, audio, graphical or other multimedia data objects, as well as structured composite items, services, programs, modules, files, documents, systems, applications, networked peers, and agents, which may be difficult or costly to be indexed. In particular embodiments the claimed invention focuses on the indexing of semantic contents and/or pragmatic characteristics of such digital resources. By tracking and analyzing the searching behavior of users, proxies, and/or meta-search-engines, a search index can be created, tuned, improved and optimized. The claimed method in certain embodiments also incorporates an adaptive and evolution mechanism which allows relevant digital resources that may otherwise be overlooked to be found. The claimed invention can be applied to databases, web searching, personal/local search, community search, and broad-based or vertical search engines for internet, intranet, extranet or other uses. | 07-08-2010 |
| 20110317885 | Automatic and Semi-automatic Image Classification, Annotation and Tagging Through the Use of Image Acquisition Parameters and Metadata - A method for characterizing image contents automatically or semi-automatically using image acquisition parameters and metadata is presented. The method establishes probabilistic and deterministic relationships between different types of metadata and the semantic attributes and contents of images. It furnishes a mechanism that enables the automatic and semi-automatic classification, annotation, tagging, indexing, searching, identification or retrieval of images based on their contents, semantic properties and metadata characteristics. The method uses, but is not limited to, image capture metadata such as focal length, exposure time, relative aperture, flash information, ISO setting, angle of view, subject distance, timestamp, GPS information as well as other forms of metadata, including but not limited to, captions, keywords, headings, tags, comments, remarks, titles which may be automatically, semi-automatically, or manually generated. The present invention can be applied to image databases, web searching, personal search, community search, broad-based or vertical search engines for internet, intranet, extranet or other usages. | 12-29-2011 |

| 20100045442 | RFID Privacy-Preserving Authentication System and Method - A system and method for RFID privacy-preserving authentication is disclosed. The method first has a reader sending a request and a first random number to a tag. The tag then generates a second random number. A plurality of hash values are then computed at the tag. Each hash value uses the first random number, the second random number and at least one part of a key of the tag as inputs. The second random number and the computed hash values are then sent to the reader. Lastly, the reader identifies a validity of the tag from the received values. The hash values are all generated in parallel and are independent to each other. | 02-25-2010 |

The fabrication process includes fabrications of an LED micro-array and an AM panel, and combining the resulting LED micro-array and AM panel using the flip-chip technology. The LED micro-array is grown and fabricated on a sapphire substrate and the AM panel can be fabricated using CMOS process. LED pixels in a same row share a common N-bus line that is connected to the ground of AM panel while p-electrodes of the LED pixels are electrically separated such that each p-electrode is independently connected to an output of drive circuits mounted on the AM panel. The LED micro-array is flip-chip bonded to the AM panel so that the AM panel controls the LED pixels individually and the LED pixels exhibit excellent emission uniformity. According to this constitution, incompatibility between the LED process and the CMOS process can be eliminated. | 12-22-2011 |
