A physical activity measuring system analyzes analyzing body motions of a user to accurately determine the exercise intensity. The system includes a portable device which is adapted to be carried by the user and is equipped with a body sensor and an indicator for indication of the exercise intensity. The body sensor senses the user's body motions to give corresponding motion strength. The portable device has a processor which constitutes an exercise calculator which has a predetermined relationship between a default standard deviation of the motion strength and an exercise intensity scale. The exercise intensity calculator collects a time series data of the motion strengths within a predetermined first time frame, obtains a standard deviation of thus collected motion strengths, and converting the standard deviation into an instant exercise intensity within the intensity scale in accordance with the predetermined relationship. The standard deviation with regard to the motion strengths can be well concordant with the exercise intensity, and therefore gives the accurate exercise intensity on a real-time basis.

The sleep diagnosis deviceof the present invention comprises three-dimensional acceleration sensorsand, a posture detectorwhich detects a posture of the patient from a DC component of the three-dimensional acceleration sensors, and a breathing movement detectorwhich detects a breathing movement of the patient from the AC component of the three-dimensional acceleration sensors. The sleep diagnosis device of the present invention can detect the posture (sleeping posture) and the breathing movement of the patient by using one three-dimensional acceleration sensor, so it is possible to reduce the number of sensors. Furthermore, the sleep diagnosis device can detect the breathing movement accurately by the three-dimensional acceleration sensors.
