  • Patent number: 11534359
    Abstract: The present invention provides an actuator-equipped knee ankle foot orthosis in which a control device calculates a thigh phase angle based on an angle-related signal detected by a thigh orientation detecting means at one sampling point, applies the thigh phase angle at that sampling point to an assisting force control data, which is stored in the control device in advance and indicates the relationship between the thigh phase angle and a size of the assisting force to be imparted to a lower leg-side brace, to obtain the size of the assisting force to be imparted to the lower leg-side brace at that sampling point, and executes operational control for an actuator unit such that the assisting force having the size is output.

  • Patent number: 11529281
    Abstract: A gait motion assisting apparatus of the present invention includes an actuator unit controlling driver so that assisting force calculated by applying gait motion timing based on detected thigh phase angle to output pattern saved data is imparted to lower leg, and a terminal device capable of wireless-communicating with control device of the actuator unit. The terminal device can receive assisting force setting value including assisting force imparting period during gait cycle and create, based on the assisting force setting value, output pattern setting data indicating a relationship between the gait motion timing and a size of assisting force to be imparted to the lower leg. The control device is configured to overwrite-save the output pattern setting data received from the terminal device as the output pattern saved data.

  • Patent number: 11504292
    Abstract: The gait motion assisting device according to the present invention replicates movement of user's leg including thigh and lower leg around hip joint by pendulum movement of a rod-like rigid body, estimates hip joint angle and hip joint angular velocity of thigh calculated based on equation of motion of the pendulum movement by a state estimator using angle-related signal received from a thigh orientation detecting means as the observation, calculates the thigh phase angle using the estimated hip joint angle and the estimated hip joint angular velocity, and outputs assisting force having torque value calculated based on the thigh phase angle.
