20090295934 | COLOR DEMOSAICKING USING DIRECTION SIMILARITY IN COLOR DIFFERENCE SPACES - Demosaicking optimizations are provided for still and/or moving image (e.g., video) processes that efficiently generate viewable images. A demosaicking process selects a direction before performing interpolation in order to avoid interpolation across edges and also to minimize color artifacts. The direction to be selected is based on a direction similarity measurement. A digital capture device can includes a system that processes the image data by performing interpolation based on the direction similarity measurement(s) for color difference spaces. The images created based on the directional similarities demonstrate performance gains in peak signal to noise ratio (PSNR). | 12-03-2009 |

20160115032 | GRAPHENE WITH VERY HIGH CHARGE CARRIER MOBILITY AND PREPARATION THEREOF - The present invention relates to a graphene film, which is obtainable by a method comprising the steps of: a) providing a substrate, b) epitaxially growing a metal layer on a surface of the substrate, c) optionally increasing the thickness of the metal layer obtained in step b) by growing a metal onto the epitaxially grown metal layer, d) peeling off the metal layer obtained in step b) or optionally in step c) from the substrate and e) depositing graphene onto at least a part of that surface of the metal layer obtained in step d), which was in contact with the substrate before the peeling off conducted in step d). Such a graphene film has a very high charge carrier mobility, namely, when measured on a SiO | 04-28-2016 |

20090135001 | Pressure sensing system - A system includes a pressure sensor communicating directly, or indirectly, via a data processor, with a feedback device. The pressure sensor is located in an athletic surface, such as in footwear, sports boards, decks, or the like, to measure the pressure and/or force transmitted to a user's leg, ankle, knee, and so forth. The feedback device produces a signal, optionally an audible, visible, and/or tactile signal, to alert the user that the pressure or force has exceeded a pressure threshold. | 05-28-2009 |

20150364710 | LIGHT EMITTING MICROCAPSULE, METHOD OF PREPARING THE SAME AND OLED DISPLAY DEVICE COMPRISING THE SAME - The present invention, which belongs to the technical field of display technology, provides a microcapsule, a method of preparing the same, and an OLED (organic light emitting diode) display device comprising the same. The OLED display device comprises a microcapsule having a phosphorescent material as a core material, which reduces the probability of the phosphorescence self-quenching and is isolated from water and oxygen, thereby improving the display quality and extending the service life of the OLED display device. Therefore, the OLED display device can solve the problem that the phosphorescence OLED display device in the prior art has a low brightness and short service life. | 12-17-2015 |

20090192990 | Method and apparatus for realtime or near realtime video image retrieval - A distributed absorbing surveillance apparatus comprising a plurality of surveillance branches at which data of a video image frame is characterised, indexed and stored locally in real-time upon capturing means browsing and searching can be conducted locally at a relatively low computational overhead upon receipt of searching instructions from a central query processor. Such a distributed surveillance apparatus also facilitates enhanced target searching speed and efficiency. | 07-30-2009 |
