  • Patent number: 9221436
    Abstract: A brake controlling unit detects a brake actuation object based on images captured by a running environment recognizing unit and sets a target brake pre-pressure actuation distance based on a relative speed between the brake actuation object and a subject vehicle. When an actual distance between the subject vehicle and the brake actuation object reaches the target brake pre-pressure actuation distance, the brake controlling unit outputs to a brake driving unit a driving signal that generates a brake pre-pressure to make the brake clearance of a brake minimal.

  • Patent number: 9061585
    Abstract: A cooling air introduction apparatus for a vehicle. A space that communicates with air introduction ports that are respectively formed in a bumper face of a front bumper and a front grille is partitioned by a vertical partition member. A space that communicates with the air introduction ports that are formed in the bumper face is partitioned by a horizontal partition member. Thus, streams of introduced cooling air are guided to heat exchangers without interfering with each other. The partition members are provided such that a bumper beam moves backward without any trouble upon a light collision.

  • Publication number: 20150156451
    Abstract: A relay apparatus (10) is provided with: an image output unit (11); switches (SWa, SWb); a control unit (16) for controlling switches; and an obtaining unit (16) for obtaining a first CEC address associated with the relay apparatus if the relay apparatus is connected to an output apparatus (30). The control unit controls switches to select a signal channel connecting a first signal transmitting device (14) and a storage apparatus (20) if the first CEC address and a reproduction command are received. After connecting the relay apparatus and a unit (40), the control unit controls switches to select the signal channel connecting the first signal transmitting device and a second signal transmitting device (15) if the unit is in a video output state, and controls switches to select the signal channel connecting the first signal transmitting device and the image output unit if the unit is in a standby state.

  • Patent number: 8903283
    Abstract: A shutter assembly includes an internal shutter and an external shutter. The internal shutter including a contact member is movable between a first position at which the internal shutter closes the outlet, a third position at which the internal shutter opens the outlet, and a second position between the first position and the third position. The internal shutter at the second position is movable to the third position while closing the outlet. The external shutter is movable between a closed position at which the external shutter closes the outlet and an open position at which the external shutter opens the outlet, and includes an interlocking member to contact the contact member to move the internal shutter. As the external shutter is moved from the closed position to the open position, the internal shutter is moved from the first position to the second position in conjunction with the external shutter.
