A CMOS sensor has unit pixels each structured by a light receiving element and three transistors, to prevent against the phenomenon of saturation shading and the reduction of dynamic range.

Routing network traffic based on social information
A technology for routing traffic from similar users to a same server cluster to improve data center efficiency is disclosed. When a traffic routing server receives a request from a user, the traffic routing server determines an identifier of a partition to which the user is assigned.

Mapping the network file system (NFS) protocol to secure web-based applications
Users on a client system access files served by a web application through the Network File System (NFS) protocol using common web authentication mechanisms while still honoring constraints imposed by the application's authorization rules. To this end, the client system is modified to include an NFS server. Following authentication of the NFS server with the web application, NFS-based requests (from a local NFS client) directed to the application are received at the NFS server instead of being sent to the application directly. The NFS server, in turn, maps those requests to the web application preferably using standard HTTP. Because the web application's normal security model is enforced as intended at the web application, the approach enables individual users of the client system to operate under different visibility constraints dictated by the web application. Thus, fine-grained permissions may be enforced at the web application for different users. |

Reflective layer for increasing fill factor in an electronic display
An electronic display includes a substrate and a thin-film transistor (TFT) layer deposited on a top surface of the substrate. The TFT layer includes a plurality of driving TFTs that are configured to provide current to one or more organic light emitting diodes (OLEDs). The electronic display also includes an emission layer deposited on a top surface of the TFT layer. The emission layer includes emission areas and non-emission areas that separate the emission areas. The emission areas include a plurality of OLEDs and each of the OLEDs are configured to be driven by one or more of the TFTs to emit light. The electronic display also includes a reflective layer formed on a bottom surface of the substrate. The reflective layer is configured to reflect at least some of the light emitted from the OLEDs toward the non-emission areas. |

Light emitting device, electronic appliance, and method for manufacturing light emitting device
To provide a light emitting device that has a structure in which a light emitting element is sandwiched by two substrates to prevent moisture from penetrating into the light emitting element, and a method for manufacturing thereof. In addition, a gap between the two substrates can be controlled precisely. In the light emitting device according to the present invention, an airtight space surrounded by a sealing material with a closed pattern is kept under reduced pressure by attaching the pair of substrates under reduced pressure. A columnar or wall-shaped structure is formed between light emitting regions inside of the sealing material, in a region overlapping with the scaling material, or in a region outside of the scaling material so that the gap between the pair of substrates can be maintained precisely. |

Method for packaging an organic light emitting diode and a display device using the same
The present invention discloses a method for packaging an organic light emitting diode: allocating a position for attaching a glass cloth tape on the packaging substrate; attaching the glass cloth tape on the position; bonding an organic light emitting diode substrate to the packaging substrate; melting the glass cloth tape, so that the organic light emitting diode substrate welds together with the packaging substrate. The present invention can avoid the presence of a welding gap, so that external gas cannot enter into an internal part of the packaging body, thereby increasing the service life of the OLED device. |
