  • Publication number: 20110269057
    Abstract: Ruthenium or a Ruthenium compound is applied to an anode structure according to a predetermined pattern, with only part of the anode active area containing Ru. The parts of the MEA that do not contain Ru are not expected to suffer degradation from Ru cross-over, so that overall degradation of the cell will be diminished. Having less precious metals will also translate into less cost.

  • Patent number: 7998884
    Abstract: A light emitting device using a silicon (Si) nanocrystalline Si insulating film is presented with an associated fabrication method. The method provides a doped semiconductor or metal bottom electrode. Using a high density plasma-enhanced chemical vapor deposition (HDPECVD) process, a Si insulator film is deposited overlying the semiconductor electrode, having a thickness in a range of 30 to 200 nanometers (nm). For example, the film may be SiOx, where X is less than 2, Si3Nx, where X is less than 4, or SiCx, where X is less than 1. The Si insulating film is annealed, and as a result, Si nanocrystals are formed in the film. Then, a transparent metal electrode is formed overlying the Si insulator film. An annealed Si nanocrystalline SiOx film has a turn-on voltage of less than 20 volts, as defined with respect to a surface emission power of greater than 0.03 watt per square meter.

  • Publication number: 20110141123
    Abstract: In various embodiments, a screen image may be divided into rectangles, and a capture component may track changed rectangles and capture the screen upon receiving an indication. For small screen updates, the capture rate may be set to ˜30 captures per second to provide a lower latency. As the screen update size increases, the capture rate may be decreased to match an allocated bandwidth. The capture rate may be increased when available bandwidth increases and decreased as bandwidth decreases. For example, the capture rate may be decreased when downstream back pressure meets predefined criteria. The capture rate change may be effected gradually to avoid jerks and jumps. Varying the capture rate by also enable audio/video synchronization with varying bandwidth variations. Some embodiments may be extended to multiple monitor solutions.

  • Publication number: 20110102443
    Abstract: Methods and systems are disclosed for virtualizing a graphics accelerator such as a GPU. In one embodiment, a GPU can be paravirtualized. Rather than modeling a complete hardware GPU, paravirtualization may provide for an abstracted software-only GPU that presents a software interface different from that of the underlying hardware. By providing a paravirtualized GPU, a virtual machine may enable a rich user experience with, for example, accelerated 3D rendering and multimedia, without the need for the virtual machine to be associated with a particular GPU product.

  • Patent number: 7916986
    Abstract: An erbium (Er)-doped silicon (Si) nanocrystalline embedded silicon oxide (SiOx) waveguide and associated fabrication method are presented. The method provides a bottom layer, and forms an Er-doped Si nanocrystalline embedded SiOx film waveguide overlying the bottom layer, having a minimum optical attenuation at about 1540 nanometers (nm). Then, a top layer is formed overlying the Er-doped SiOx film. The Er-doped SiOx film is formed by depositing a silicon rich silicon oxide (SRSO) film using a high density plasma chemical vapor deposition (HDPCVD) process and annealing the SRSO film. After implanting Er+ ions, the Er-doped SiOx film is annealed again. The Er-doped Si nanocrystalline SiOx film includes has a first refractive index (n) in the range of 1.46 to 2.30. The top and bottom layers have a second refractive index, less than the first refractive index.

  • Patent number: 7860520
    Abstract: The embodiments of the present invention disclose a method for issuing paging messages and an MSC/VLR, the method includes: determining types of networks terminating the process, if the MS only accesses a 2G network; issuing, by the MSC/VLR, paging messages on an RNC, and terminating the process, if the MS only accesses a 3G network; and issuing, by the MSC/VLR, paging messages on both the BSC and RNC, if the MS accesses both the 2G network and the 3G network. According to the embodiments of the present invention, the MSC/VLR can choose to issue paging messages on the BSC or the RNC separately or on both the BSC and the RNC, since it can determine the types of networks accessed by the MS. Thus, unnecessary paging messages issued on the BSC same time, a great deal of radio paging channel resources on the BSC or the RNC is saved, which greatly reduces effects on the process of paging other MSs.
