  • Publication number: 20100285372
    Abstract: A lithium metal thin-film battery composite structure is provided that includes a combination of a thin, stable, solid electrolyte layer [18] such as Lipon, designed in use to be in contact with a lithium metal anode layer; and a rapid-deposit solid electrolyte layer [16] such as LiAlF4 in contact with the thin, stable, solid electrolyte layer [18]. Batteries made up of or containing these structures are more efficient to produce than other lithium metal batteries that use only a single solid electrolyte. They are also more resistant to stress and strain than batteries made using layers of only the stable, solid electrolyte materials. Furthermore, lithium anode batteries as disclosed herein are useful as rechargeable batteries.

  • Patent number: 7792540
    Abstract: The present invention relates to synchronizing a terminal and a server in a shadow area of service in a push-to-talk (PTT) service system. An alive report packet is periodically transmitted to a server by a terminal having no permission to send a talk burst. A talk burst idle packet is periodically transmitted to each session-established terminal by the server in an idle state. Sessions are ended between each terminal and server if either the alive report packet or the talk burst idle packet are not received for a certain time. Accordingly, synchronization between the server and the terminal is periodically certified, unnecessary traffic generated due to inconsistent synchronization is decreased, and quality of service is enhanced.

  • Publication number: 20100055573
    Abstract: A reverse configuration, lithium thin film battery (300) having a buried lithium anode layer (305) and process for making the same. The present invention is formed from a precursor composite structure (200) made by depositing electrolyte layer (204) onto substrate (201), followed by sequential depositions of cathode layer (203) and current collector (202) on the electrolyte layer. The precursor is subjected to an activation step, wherein a buried lithium anode layer (305) is formed via electroplating a lithium anode layer at the interface of substrate (201) and electrolyte film (204). The electroplating is accomplished by applying a current between anode current collector (201) and cathode current collector (202).

  • Publication number: 20090254819
    Abstract: A spelling correction system and method automatically recognizes and corrects misspelled inputs in an electronic device with relatively lower computing power. In a learning process, a misspelling correction dictionary is constructed on the basis of a corpus of accepted words, and context-sensitive strings are selected from among all the strings registered in the dictionary. Context information about the context-sensitive strings is acquired. In an applying process, at least one target string is selected from among all the strings in a user's input sentence through the dictionary. If the target string is one of the context-sensitive strings, the target string is corrected by use of the context information.
