    Abstract: A myoelectric sensor for detecting myoelectric signals which accompany body movement includes: a wearing band that is elastic, expandable, and circular, and that is worn around a limb to surround the limb tightly; myoelectric detection units a plurality of which are disposed in the circumferential direction on the wearing band with intervals therebetween so as to cause each of a plurality of myoelectric detection electrodes to be in close contact with the surface of the limb, and which detect myoelectric signals from corresponding positions on the limb using the myoelectric detection electrodes; and connection cables that electrically connect mutually adjacent myoelectric detection units and thereby transmit the myoelectric signals. The connection cables each include a bent portion, the bent shape of which changes in response to changes in the distance between the mutually adjacent myoelectric detection units.

    Abstract: A fluid concentration measuring device measures the concentration of a fluid flowing through a duct having a light-transmissive, deformable duct wall. The device includes a light source; a light receiving element which receives the light, which passed through the wall of the duct and the fluid inside the duct, and outputs a signal indicating the intensity of the light; light path distance setting means and fluid concentration output means which obtains a plurality of relational expressions, which indicate the relation between the light intensity and the fluid concentration when the light from the light supply part is received by the light receiving part over each of the light path distances, and obtains the fluid concentration from the light intensity at the light receiving part based on the relational expressions for the plurality of light path distances and outputs the fluid concentration.

    Abstract: A triaxial acceleration sensor and a triaxial angular rate sensor are mounted on each of the lower limb portions on both sides of one joint among joints constituting a part of one lower limb of a subject. The acceleration and angular rate of each lower limb portion are measured by the triaxial acceleration sensor and triaxial angular rate sensor while the subject is walking. The orientations of each lower limb portion while walking are calculated on the basis of the measured acceleration and angular rate. A three-dimensional model including the motion trajectory of one joint is constructed by linking the lower limb portions in the calculated orientation to each other. The angle formed by the acceleration vector of one joint when the heel strikes the ground to the movement trajectory in the sagittal plane is calculated as a gait parameter.

    Abstract: A transmitted light intensity measurement unit for measuring a concentration of fluid flowing through a duct comprises: a light source for supplying light into the duct from a light supply part on a surface of the duct; a light receiving element for receiving the light, which has been passed from the light supply part through the duct wall and the fluid inside the duct, at a light receiving part located on an opposite side in a diametrical direction of the duct relative to the light supply part, and outputs a signal indicating an intensity of the light; and a light-transmissive member disposed on at least one light path among a light pass between the light source and the light supply part and a light pass between the light receiving element and the light receiving part, abutting and closely contacting the duct wall by an elastic deformation of the duct wall.
