  • Publication number: 20150181329
    Abstract: A beam-forming device includes a first target sound blocker 103 and a second target sound blocker 104 that remove a target signal having a correlation mutually from a first sound signal x1 and a second sound signal x2 which are converted by first and second microphones 101 and 102, a phase synchronizer 105 that synchronizes the phases of the first sound signal x1 and the second sound signal x2 and synthesizes these sound signals by using information acquired when the first target sound blocker 103 removes the target signal, and a noise learner 106 that learns a noise component included in an output signal of the phase synchronizer 105 from signals from which the target signal is removed by the first target sound blocker 103 and the second target sound blocker 104.

  • Publication number: 20140295037
    Abstract: A method, a program, and a device for evaluating food preference of pets that do not require humans to eat a pet food itself. The preference of pets can be evaluated by conducting sensory analysis on selected palatants contained in a pet food by humans. Accordingly, highly precise prediction of the preference can be made by a simple and intuitive method based on sensory attributes for human. Further, humans are not required to eat a pet food itself because the humans may conduct sensory analysis on selected palatants contained in the pet food.

  • Publication number: 20140064514
    Abstract: A target sound enhancement device 10 has a first beamformer 16 and a second beamformer 17 which are of different types. A vehicle interior environment model in which this target sound enhancement device 10 is mounted is stored in a vehicle interior environment model storage unit 13. A beamformer type determining unit 14 selects a most suitable beamformer according to the vehicle interior environment model for each of predetermined frequency bands, and a BF selector 15 outputs a signal in each frequency band to the beamformer selected. A signal combining unit 18 combines signals in the frequency bands in each of which the driver's voice outputted from the first beamformer 16 or the second beamformer 17 is enhanced.

  • Publication number: 20070106776
    Abstract: For the first use of an authentication device, a remote machine makes a query of an address of a local machine to be permanently assigned to the remote machine, to which the authentication device is connected, to a management server. In response to the query, the management server determines the local machine to be permanently assigned to the remote machine and notifies the remote machine of an address of the local machine. The remote machine remotely controls the local machine specified by the address notified from the management server.

  • Publication number: 20050164754
    Abstract: Grains are put into a test tube containing a specific reagent solution and are stirred to produce a reactive solution and this solution is put into a cell. A light is irradiated to the cell to detect an absorbance at a wavelength where the absorbance reaches a peak and an absorbance in a wavelength region in which the absorbance hardly varies. Then, freshness of the grains and beans is judged based on a difference between the two absorbances.
