專利摘要(中)
一種步態監控與保健系統包含第一IMU、第二IMU及近端主機。第一IMU感測大腿的活動狀態而產生第一活動信號。第二IMU感測小腿的活動狀態而產生第二活動信號。近端主機包含微處理器及警示器。微處理器執行以下動作：依據第一活動信號和第二活動信號計算出第一IMU與第二IMU分別相對於水平面的第一仰角和第二仰角；依據第一仰角和第二仰角計算出膝關節的活動資訊，活動資訊包含膝關節的彎曲角、角速度及持續時間；以及依據活動資訊判斷膝關節的彎曲角是否落入危險範圍內，若是，則控制警示器輸出警示信號。

專利摘要(英)
A gait monitoring and healthcare system includes a first IMU, a second IMU and a local host. The first IMU senses an activity state of a thigh and generates a first activity signal. The second IMU senses an activity state of a calf and generates a second activity signal. The local host includes an alarm and a microprocessor, which performs operations of: calculating a first pitch angle between a horizontal plane and the first IMU and a second pitch angle between the horizontal plane and the second IMU according to the first activity signal and the second activity signal; calculating activity information of a knee joint, including a bending angle, an angular velocity and a duration of the knee joint, according to the first pitch angle and the second pitch angle; and judging whether the bending angle of the knee joint falls within a dangerous range or not according to the activity information, and controlling the alarm to output a warning signal if not.
