  • Patent number: 12147060
    Abstract: An image stabilizing apparatus includes a driver configured to drive an optical system configured to correct an image blur in a direction that includes a component in a direction orthogonal to an optical axis, detectors configured to detect position information on the optical system, and a controller configured to control the driver. The detectors are disposed at a first detecting position and a second detecting position on a plane orthogonal to the optical axis. At the first detecting position, position information in a first detecting direction and position information in a second detecting direction different from the first detecting direction are detected. At the second detecting position, position information in a third detecting direction is detected. At least two of the first to third detecting directions are orthogonal to each other.

  • Patent number: 12115889
    Abstract: A vehicle entry-and-exit assistance device easily moves a board between a housed position and a using position. Embodiments include a board at an outer side of a seat adjacent to a door opening, the board rotatable between a horizontal posture and an orthogonal posture; a board support portion rotatable between a seat side-position and a flipped-up position; and a linking mechanism. The board pivots around an axis orthogonal to the vehicle width direction, and the support portion pivots around an axis extending in the vehicle width direction. The linking mechanism rotates the board to a vehicle-width-direction inner side with respect to the support portion to take the orthogonal posture when the support portion is rotated to the flipped-up position, and rotates the board to a vehicle-width-direction outer side with respect to the support portion to take the horizontal posture when the support portion is rotated to the seat side-position.
