  • Patent number: 7002548
    Abstract: A drive controller for controlling to change the orientation of a display surface of a display in accordance with the seating position of occupants aboard a vehicle. A display unit is rotatably mounted on a vehicle. A controller automatically rotates the display unit to a first position where the display surface is oriented toward a driver seat, when an occupant is seated solely in the driver seat. The controller rotates the display unit to a third position where the display surface is oriented toward a front passenger seat, when an occupant is seated solely in the front passenger seat. The controller rotates the display unit to a second position where the display surface is oriented toward the middle point between the driver seat and the front passenger seat, on detecting both of the occupants are seated respectively in the driver seat and the front passenger seat.

  • Patent number: 6995755
    Abstract: A display controller for controlling display on a display surface of a display unit mounted on a vehicle. The display unit is rotatably mounted on the vehicle. A CPU of a controller recognizing that the vehicle is traveling, that a display surface of a display unit is oriented toward the driver's seat, and that a moving picture is displayed on the display surface, inhibits display of the moving picture on the display unit. The CPU of the controller, recognizing that the vehicle is traveling, that the display surface of the display unit is oriented toward the driver's seat, and that a moving picture is displayed on the display surface rotates the display unit to a position where an occupant of the driver's seat cannot watch the moving picture.

  • Publication number: 20040252985
    Abstract: A data transfer and reproduction system which transfers contents data such as music and the like from a master device such as a personal computer and the like to a slave device such as a car-mounted audio device and the like, without putting an operational burden on a user. Certification is registered between the slave device and the master device which transfers contents data, and contents data is transferred between the devices the certification of which has been registered. Of contents data stored in memory in the master device, contents data with a “yet-to-be transferred” identifier is transferred to the slave device at predetermined timing. When the functional disturbance of the slave device is detected during transfer, the transfer of contents data is aborted. The timing of the transfer may be in accordance with a predetermined time schedule, or a transfer command from the user.

  • Publication number: 20040252846
    Abstract: A noise reduction apparatus is capable of suppressing deterioration of an aural sensing level due to noise existing in a sound field. The apparatus synthesizes a signal obtained by adding a predetermined delay to a sound field noise and reversing and amplifying the signal with an electric signal from a sound reproduction system to obtain a sound pressure output by using a first signal processing part. On the other hand, the apparatus synthesizes a signal obtained by delaying an electric signal from the sound reproduction system by a predetermined period and reversing and amplifying the signal with an electric signal obtained from a sound pressure in the proximity of a concha of a listener to extract a residual noise component by using a second signal processing part. The apparatus controls the delay amounts and the gains set by the first and second signal processing parts so as to minimize an extraction signal.
