  • Patent number: 8930476
    Abstract: A method is disclosed for folder transfer based on instant messaging (IM). The method includes receiving from an IM sender a transfer request for transferring a folder-to-be-transferred. The folder-to-be-transferred may contain a plurality of files. The method also includes receiving from the IM sender folder information of the folder-to-be-transferred, determining a receiving folder corresponding to the folder-to-be-transferred on a predetermined storage location, and determining files-to-be-transferred from the plurality of files corresponding to the folder-to-be-transferred based on the folder information. Further, the method includes sequentially sending one transfer request for each of the files-to-be-transferred to the IM sender through a same network connection, receiving the files-to-be-transferred sent sequentially by the IM sender through the same network connection, and storing the received files-to-be-transferred in the receiving folder.

  • Publication number: 20140341086
    Abstract: The present disclosure discloses a method, apparatus and system for transmitting multimedia data. After accessing to a multimedia conference room, a client encodes multimedia data to be transmitted, and transmits the encoded multimedia data to a multi-point control unit. The client receives a multimedia data packet sent by the multi-point control unit. The multimedia data packet is obtained by the multi-point control unit via encapsulating multimedia data sent by at least one client in the multimedia conference room. The client decodes the multimedia data packet, composes multimedia data obtained after decoding the multimedia data packet, and displays the composed multimedia data.

  • Publication number: 20140170491
    Abstract: A composition is provided that includes mesoporous carbon domains. Each of the mesoporous carbon domains is incorporated with particles of metal or metal oxide in an amount of from 40 to 85 total weight percent of the composition. The metal or metal oxide particles can include tin, cobalt, copper, molybdenum, nickel, iron, or ruthenium, or an oxide thereof. The resulting composition when combined with a binder from a battery electrode. Such a battery electrode operating as an anode in a lithium ion battery has specific capacities of more than 1000 miliAmperes-hour per gram after 15 of the galvanostatic cycles.

  • Publication number: 20120097917
    Abstract: Aligned nanowire arrays were coated with semiconductor shell layers, and optionally with noble metal nanoparticles for use as three dimensional gas sensors. The sensors show room-temperature responses to low concentrations of various gases. Arrays containing different sensor types can discriminate among different gases, based upon changes in conductivity and response times.
