Patent number: 11484224Abstract: 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.Type: GrantFiled: July 22, 2016Date of Patent: November 1, 2022Assignees: NIPRO CORPORATION, HARADA ELECTRONICS INDUSTRY CO., LTD.Inventors: Shigeru Tadano, Ryo Takeda, Harukazu Tohyama, Yoshihiko Sano, Masahide Harada

Patent number: 10702182Abstract: 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.Type: GrantFiled: January 12, 2016Date of Patent: July 7, 2020Assignees: NIPRO CORPORATION, HARADA ELECTRONICS INDUSTRY CO., LTD.Inventors: Shigeru Tadano, Yoshihiko Sano, Masahide Harada
