  • Telomerase inhibitors and methods of their use
    Patent number: 6518268
    Abstract: Thiazolidinedione compounds, compositions, and methods of inhibiting telomerase activity in vitro and treatment of telomerase mediated conditions or diseases ex vivo and in vivo are provided. The methods, compounds and compositions of the invention may be employed alone, or in combination with other pharmacologically active agents in the treatment of conditions or diseases mediated by telomerase activity, such as in the treatment of cancer. Also disclosed are novel methods for assaying or screening for inhibitors of telomerase activity.

  • Speech detecting device and speech detecting method
    Patent number: 6490554
    Abstract: The invention relates to a voice activity detecting device and a voice activity detecting method. An object of the invention is to adapt to various characteristics of noise which may possibly be superimposed on an aural signal to thereby reliably discriminate between an active voice segment and a non-active voice segment. For this purpose, the voice activity detecting device comprises: a speech-segment inferring section 11 for determining the probability that each of active voice frames given in order of time sequence belongs to the active voice segment, based on the statistical characteristic of the aural signal; a quality monitoring section 12 for monitoring the quality of the aural signal for each active voice frame, and a speech-segment determining section 13 for weighting the determined probability with the above quality to obtain for each active voice frame the accuracy that the active voice frame belongs to the active voice segment.

  • Transfer and display of virtual-world data
    Patent number: 6055563
    Abstract: A method of displaying a virtual world in a client device based on virtual-world-description data received from a server device via a communication line. The method includes the steps of receiving description-data segments one by one into which the virtual-world description data is divided, and displaying a virtual-world segment at every turn when receiving one of the description-data segments, the virtual-world segment being a portion of the virtual world which is described by the one of the description-data segments.
