When the subject bends the knee or does not feel the sensor group, the sensor outputs an invalid result (such as low level); when the subject does not bend his or her knee or his or her foot touches the sensor group, the sensor outputs a valid result (e.g., a high level). After the test is started, the control processing module continuously monitors the result of the inductor, and once the result of the inductor output invalidation in the test process is judged to be that the knee is bent or the toe is not separated, the test is invalid.
