  • Publication number: 20170316086
    Abstract: An input method, device and electronic apparatus are provided. The input method includes acquiring text information at an input cursor position, where the text information includes above text information located before the input cursor and/or below text information located after the input cursor; extracting keywords from the text information; searching through associative candidate lexicons of the keywords to obtain an enter-on-screen candidate word queue at the input cursor position; outputting the enter-on-screen candidate word queue. By acquiring the text information at the input cursor position and determining the enter-on-screen candidate word queue based on the keywords in the text information, embodiments of the present disclosure solve the issue in existing techniques that after the input cursor changes it position, no enter-on-screen candidate word may be provided by association because no reliable enter-on-screen entry is obtained.

  • Patent number: 9559364
    Abstract: A solid oxide fuel cell having a plurality of planar layered fuel cell units, an electrically conductive flow separator plate disposed between each of the fuel cell units, and a cathode contact material element disposed between each cathode electrode of the fuel cell units and each electrically conductive flow separator plate. The cathodes of the individual fuel cell units are modified such that the operating temperatures of the cathodes are matched with the temperatures they experience based upon their locations in the fuel cell stack. The modification involves adding to the cathode contact material and/or cathode at least one alloying agent which modifies the temperature of the cathode electrodes based upon the location of the cathode electrodes within the fuel cell stack. These alloying agents react with a component of the cathode electrode to form alloys.
