  • Publication number: 20080183798
    Abstract: A data synchronization method is disclosed by which a data synchronization process is performed automatically between a plurality of information apparatus. A record which forms data possessed by each information apparatus includes a data item representative of deletion information of the record and another data item. Time stamp information is fetched for each of the data items. A first one of the information apparatus transmits self data thereof including the time stamp information to a second one of the information apparatus which is a destination of data synchronization. Upon reception of the data transmitted from the first information apparatus, the second information apparatus compares the time stamp information for each of the data items included in the record of an updating object between the received data and the self data thereof and fetches the newest data to update the self data thereof.

  • Publication number: 20060240419
    Abstract: A method for detecting a genetic polymorphism(s), comprising creating oligonucleotide probes and/or oligonucleotide primers so that the probes and/or primers contain a polymorphic site(s) present in a gene encoding a receptor or a sequence complementary thereto or so that the polymorphic site(s) is/are contained in the amplified fragment when at least one of said gene encoding the receptor and said sequence complementary thereto is amplified; and detecting at least one genetic polymorphism in a gene of a subject encoding the receptor using the resultant oligonucleotide probes and/or oligonucleotide primers.

  • Patent number: 6320958
    Abstract: In a remote conference system based on a client server model, each of conference terminals comprises a terminal packet memory for storing a voice data of the conference terminal. When a synthesized voice data is multicasted to the conference terminals, each of the conference terminals searches own voice data included in the synthesized voice data from the terminal packet memory. An echo canceler in each of the conference terminals cancels own voice data from the synthesized voice data, thereby performing an echo canceling processing.
