    Abstract: At least one optical fiber of a fiber sensor has sensing parts whose number is number of the anticipated inflection points+one or more, the anticipated inflection points being inflection points of a shape of a detection target range of a detection target. The number of the anticipated inflection points is decided based on one of a functional limit and a structural limit which limit a degree of freedom in a bending shape of the detection target. A space L1 between the anticipated inflection points is L1=r1·θ1, wherein r1 is a curvature radius at a maximum bending of the detection target range of the detection target, θ1 is a central angle of an arc created by the space between the anticipated inflection points at the maximum bending, and θ1≧π/2.

    Abstract: An movement assistance system includes a processor. The processor detects a position in picked-up images of an image of an image pickup target, causes a memory to store the position, estimates a change in the position of the image pickup target, estimates the position of the image pickup target and performs control for causing a display apparatus to display an estimation result of the position of the image pickup target, when detecting a disappearance state in which the image of the image pickup target is not detected, and performs control for causing the display apparatus not to display the estimation result of the position of the image pickup target when detecting, after the image pickup target is brought into the disappearance state, that a position indicated by the estimation result of the position of the image pickup target is a position inside an output determination region.

    Abstract: An insertion system includes an insertion section and a rigidity variable portion provided in the insertion section. The rigidity variable portion includes a superelastic alloy member whose rigidity starts changing from a high-rigidity state to a low-rigidity state at a temperature, which varies with a degree of bending of the superelastic alloy member, and a heating member capable of switching between presence and absence of heating of the superelastic alloy member. The insertion system also includes a bending state detection sensor that detects a bending state of the rigidity variable portion, and a rigidity variable controller that controls switching between presence and absence of heating of the superelastic alloy member by the heating member to control the temperature of the superelastic alloy member.
