Abstract: An electrocardiographic transmitter executes statistical processes for an electrocardiographic signal to calculate an average value HRav of a heart rate HR in a predetermined period of time. In a case where the average value HRav of the heart rate HR is abnormal, the electrocardiographic transmitter continuously transmits electrocardiogram data based on the electrocardiographic signal to a terminal. The terminal receives and transfers the electrocardiogram data as it is to a host device. The host device stores therein and supplies the transferred electrocardiogram data for a diagnosis by medical worker. Thus, the state of a subject's heart can be monitored over the long term.

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 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.
