US Patent 11266879 Adaptive active training system

An adaptive active training system includes a motion module, a sensing module and a control module. The motion module includes a training unit and a motor connected to the training unit. The motor is configured to bring the training unit to move along a motion trajectory. The sensing module is configured to sense a physiological signal of a user when the user uses the training unit. The control module is connected to the motion module and the sensing module. The control module is configured to calculate a position of the training unit on the motion trajectory, obtain a threshold value corresponding to the position based on a motion model, and determine whether a magnitude of the physiological signal is greater than the threshold value.
