  • Patent number: 11153666
    Abstract: The embodiments of the present application provide a method and an apparatus for releasing a video file, which are applied to a server. The method comprises obtaining a video file to be released; selecting a first preset number of video frames in the video file to be released; generating a target video file using the selected video frames; determining a target display position for the target video file in a video preview interface; and storing the correspondence between the target display position and the target video file so that a first terminal logging in the server plays the target video file at the target display position in the video preview interface based on the correspondence. As can be seen, since the first terminal plays the target video file at the target display position in the video preview interface, the user can get more information about the content of the video file to be released from the target video file, so that the user experience is improved.

  • Patent number: 11121278
    Abstract: The use of photovoltaic (PV) cells to convert solar energy to electricity is becoming increasingly prevalent; however, there are still significant limitations associated with the widespread adoption of PV cells for electricity needs. There is a clear need for a high efficiency solar power system that supplies electricity at a competitive cost and that provides for an on-demand supply of electricity as well as energy storage. By combining aspects of concentrated solar power and concentrated photovoltaics, the present invention provides a device that enables the conversion of sunlight to electricity at very high efficiencies and that enables the transmission of thermal energy to heat storage devices for later use. The disclosed device enables transmissive CPV through the use of a multijunction PV cell mounted on a transparent base. The use of a multijunction cell allows for highly efficient absorption of light above the bandgap of the lowest bandgap subcell.

  • Patent number: 11091708
    Abstract: A process for treatment of PFO from a steam cracking zone includes selectively hydrogenating PFO or a portion thereof for conversion of polyaromatics compounds contained in the PFO into aromatic compounds with one benzene ring to produce a selectively hydrogenated stream. The selectively hydrogenated stream is reacted in the absence of added hydrogen for selective ring opening and dealkylation to produce a dealkylated BTX+ stream. The dealkylated BTX+ stream is separated into BTX compounds. Optionally the PFO is separated into a first stream containing C9+ aromatics compounds with one benzene ring, and a second stream containing C10+ aromatic compounds, whereby the first stream containing C9+ aromatics compounds with one benzene ring is passed to the ring opening step, and the feed to the selective hydrogenation step comprises all or a portion of the second stream containing C10+ aromatic compounds.
