  • Patent number: 11932221
    Abstract: A system and method control an automobile by decelerating the automobile at a first deceleration using a braking mechanism in response to detecting that a parking brake switch is turned on, a second deceleration which is smaller than the first deceleration, in response to not detecting that the parking brake switch is turned on and determining that the driver is incapacitated, and a third deceleration which is smaller than the first deceleration, in response to determining that an SOS switch is turned on, detecting that the parking brake switch is changed from on to off, and not determining that the driver is incapacitated.

  • Patent number: 8708444
    Abstract: A head includes first and second outlet rows, and records uniform images in check regions. In each uniform image, a combination of a first dot row formed with the first outlet row and a second dot row formed with the second outlet row while being spaced apart from the first dot row in a movement direction is repeatedly arranged with a repeat pitch in its direction. When recording the uniform image in each check region, a distance obtained by changing a reference distance, which is half the repeat pitch, by a set shift amount is assigned as a distance between each first dot row and each second dot row, the set shift amount being progressively changed for the check regions. A maximum density check region is specified, and ejection timing of the second outlet row is corrected based on the set shift amount corresponding to the maximum density check region.
