  • Patent number: 9741345
    Abstract: A method for segmenting video and audio into clips using speaker recognition is provided to segment audio according to speaker audio, and to make audio clips correspond to the audio and video signals to generate audio and video clips. The method instantly trains an independent speaker model by increasing an unknown speaker source audio signal, and the speaker recognition result is applied to determine the audio and video clips. Independent speaker clips of source audio are determined according to the speaker model and the speaker model is renewed according the independent speaker clips of source audio. This method segments audio by the speaker model without waiting for complete speaker feature audio signals to be collected. The method is also able to segment the audio and video into clips based on the recognition result of speaker audio, and can be used to segment TV audio and video into clips.

  • Patent number: 7731318
    Abstract: A pneumatic ink-jet system is applied in an inkjet printer and uses a negative pressure generator, which is designed according to the Bernoulli's Theory, with a stable airflow in a certain speed to generated stable pressure inside at least one inkpot and at least one print head. Therefore, the at least one print head is kept in an appropriate wet state and the quality of printing is enhanced. Moreover, a top surface of the ink inside the at least one inkpot can be controlled to be higher than the at least one print head, so the pneumatic ink-jet system can be applied in a large format inkjet printer.
