  • Device control apparatus and device control method
    Patent number: 9362770
    Abstract: A device control apparatus according to an embodiment includes a monitoring unit, a first processing unit, and a second processing unit. The monitoring unit monitors a state of voltage supply from a battery. When the start of the voltage supply is detected, the first processing unit starts the voltage supply to some devices, operates in a first operation mode, and executes a resume process of the devices. When the resume process is completed, the second processing unit starts the voltage supply to devices other than some devices, initializes states of the devices, and operates in a second operation mode in which consumption power is larger than consumption power of the first operation mode.
    Type: Grant

  • Apparatus for reproducing sound field
    Patent number: 5285503
    Abstract: This invention relates to a audio system installed in a vehicle. An apparatus for reproducing a sound field according to the invention includes a fader controlling circuit for separating a sound signal into predetermined channels to adjust a level of each separated sound signal depending on an amount of manipulation of a fader manipulating part, a sound field controller for performing a computing process of each sound signal obtained by the fader controlling circuit to form a desired sound inside a vehicle, and a relieving part invalidating a separate adjustment for the sound signal caused by the manipulation of the fader manipulating part while the sound field controller is operated.
