Abstract: An information processing device acquires vehicle information including position information of a vehicle and state information of the vehicle. Further, the information processing device identifies an actual position where a wheelchair user has a record of boarding or exiting the vehicle based on the vehicle information. Then, the information processing device adds information on the actual position to a database.

Abstract: A projection apparatus projects a pattern image onto an object so as to detect, by a phase difference scheme, a focus state of a phototaking system or observation system. The projection apparatus includes a first projecting system for projecting a first pattern extending in a first direction to a plurality of positions arranged in the first direction and including a central focus detection region on the object and a second projecting system for projecting a second pattern extending in a second direction to a plurality of positions arranged in the second direction and including the central focus detection region on the object.

Abstract: There is disclosed a pattern projection device for a camera having a plurality of right, left, upper, and lower focus detection regions in the view field region, which device has an optical unit for splitting a pattern having a predetermined shape into a plurality of patterns in each of the vertical and horizontal directions so as to project the pattern onto the plurality of focus detection regions.

Abstract: A swinging hook apparatus, rotatably mounted on a pivotal shaft on a conveyor chain, comprising a swinging hook having an abutting surface for detachably engaging with conveyor goods and formed above the pivotal shaft of the swinging hook and having an external force action surface formed below the pivotal shaft with a bearing of the pivotal shaft mounted, through a shock absorber, on the swinging hook support in a longitudinal direction of the conveyor chain.
