Abstract: Load input to an impact detector can be increased when a localized load is input, in comparison to when load is input to a comparatively wide region. In the vehicle side door structure 10, when a localized load is input, for example due to an impact to an outer panel 18 of a pole, or the like, to a length direction intermediate portion of an impact beam 26, via the outer panel 18, the outer panel 18 locally approaches the inner panel 20 side due to the length direction intermediate portion of the impact beam 26 bending, and a load is input to the vehicle width direction outer-edge portion of the sensing bracket 32. As a result, load is transmitted to the inner panel 20, via the horizontal section 32B and an inner-side joint section 32A of the sensing bracket 32, and also load (acceleration, displacement or the like) is input to an acceleration sensor 40 attached to the inner panel 20.

Abstract: An image of a region is taken which includes a two-dimensional code. A two-dimensional code area is determined in the image. The two-dimensional code area corresponds to the two-dimensional code. Inspection lines are set which connect opposite sides in two pairs among four sides indicating boundaries of the two-dimensional code area in cases where the two-dimensional code is of a cell matrix type. Inspection lines are set which connect opposite sides in one pair among four sides indicating boundaries of the two-dimensional code area in cases where the two-dimensional code is of a bar-code stack type. Information is read from the two-dimensional code area on the basis of the inspection lines. Division points are set on the opposite sides in response to a ratio in length between sides adjacent to the opposite sides and a number of arrangements of cells in the two-dimensional code in cases where the two-dimensional code is of the cell matrix type.
