Abstract: In a heel position estimation device, a contour extractor extracts, from a one-foot image of a measurement subject, a contour shape of a foot part that includes at least part of a heel portion. A determination unit determines the type of the contour shape. A heel estimation unit estimates a heel point position in the contour shape, based on the type of the contour shape determined.

Abstract: A foot pronation estimation apparatus includes a pronation estimator that estimates a degree of pronation of a foot, with reference to comparison between a feature value of a predetermined part and a reference value. A feature value extractor extracts, from a top-view image, feature values of a plurality of parts including at least a width of foot and an amount of a recess of an arch shape. A pronation estimator estimates a degree of pronation of the foot, with reference to comparison of each of the feature values of the plurality of parts including at least the foot width and the amount of the recess of the arch shape, with an individually corresponded reference value. The feature values of the plurality of parts further include foot length and an amount of protrusion in an outline shape near a little toe ball.

Abstract: A shock absorber includes a cylinder, a sleeve provided so as to surround the outer circumferential surface of the cylinder, the cylinder formed of a different material from a material for the cylinder, first and second springs provided along the outer circumferential surface of the sleeve, and a slider provided between the first spring and the second spring, and capable of being displaced in an axel direction. The materials for the cylinder and the sleeve are a combination of materials that causes corrosion due to a contact of either one of those with the other one of those. A corrosion inhibitor is provided which suppresses an occurrence of corrosion on the cylinder or on the sleeve. In one embodiment, the materials are metals.

Abstract: In a shoe fit evaluation system, a dimensional difference calculator calculates a part dimensional difference, which is a difference between a measurement value of a foot part dimension and a last part dimension corresponding to the foot part, by performing a certain adjustment for the part. An evaluation processor calculates a last matching rate based on the part dimensional difference. An outputter outputs information regarding the last matching rate. The dimensional difference calculator calculates the part dimensional difference by performing, as the certain adjustment, subtraction of an allowance for specific stretch properties of each shoe part.

Abstract: A foot shape measurement apparatus acquires a plurality of foot images captured by an imaging unit imaging a subject’s foot from a plurality of angles, and generates a three-dimensional model of the foot. A display controller displays, a target mark indicating a viewpoint position where an imaging viewpoint by the imaging unit in the augmented reality space forms a predetermined angle to the subject’s foot and a state mark indicating a current state of the imaging viewpoint by the imaging unit in the augmented reality space to be superimposed on a visual being captured by the imaging unit. An image acquisition unit acquires, as the foot image, the image to be captured when the imaging viewpoint is present in the imaging viewpoint by which a display state of the target mark and a display state of the state mark each satisfy a predetermined condition.

Abstract: In a foot size measurement system, a measurement unit selectively measures one or more of multiple measurement elements to be measured as feature values defining one foot size, based on a one-foot image of a measured person. An information generator generates foot size information based on one or more measurement elements selectively measured by the measurement unit, among the multiple measurement elements. An output unit outputs the foot size information. The measurement unit selectively measures one or more of multiple measurement elements including a foot width and a foot length of one foot of a measured person.

Abstract: A steering structure for a saddle riding vehicle includes a suspension arm, a head pipe supported by a tip portion of a suspension arm, a stem shaft pivotably inserted through the head pipe, a front fork structure body integrally pivotably connected to a lower end portion of the stem shaft, a handle support section disposed above the head pipe, a handle steerably supported by the handle support section, and a bending link configured to transmit a steering operation of the handle toward a front wheel, wherein the bending link has an upper end portion connected to a side of the handle and a lower end portion connected to a side of the front fork structure body.

Abstract: A drive unit includes: a pedal crankshaft to which a pedal stepping force of a rider is applied; an electric motor that detects a torque input to the pedal crankshaft and generates a drive force; and a transmission that changes shift of the drive force of the electric motor and delivers the drive force to the pedal crankshaft, the transmission includes a main shaft that supports a plurality of drive gears and a counter shaft that supports a plurality of driven gears that engage with the plurality of respective drive gears, and the transmission selects one torque delivery gear among the plurality of drive gears, delivers the drive force of the electric motor to the counter shaft, and shifts the torque delivery gear without inverting a rotational direction of the drive gear.
