    摘要： Systems and methods for operating autonomous lower limb devices, including at least one adjustable joint and configured for at least supporting a body are provided. A method includes collecting real-time sensor information associated with the autonomous lower limb device. The method also includes receiving, over a communications link, remote data for at least one other lower limb device configured for supporting the body. The method further includes generating control data for transitioning the autonomous lower limb device from a current state in a current finite state model for operating the autonomous lower limb device to a different state in the current finite state model, where the different state is selected based on the real-time sensor information and the remote data.

    摘要： A prosthetic lower leg uses one or more generally C-shaped spring elements between the patient's socket and a footplate assembly. The respective connections between (a) those one or more elements and (b) that socket and that footplate can be configured to provide a lightweight and economic prosthesis that effectively mimics the feel and performance of a normal human foot. The prosthetic spring element is generally C-shaped, and can have a substantially constant thickness along its length, lending itself to being fabricated by automated processes such as filament winding. One or more of the generally C-shaped spring elements can be incorporated into other prostheses and/or other devices.

    摘要： A lower leg prosthesis (1) comprises a distal end (for) having an artificial foot (5) and a proximal end (for) having a stump socket (7) for connection to a leg stump of an amputee. The prosthesis comprises a mechanism (10) which is arranged such that, in use condition of the prosthesis and in an upright position of said amputee with said artificial foot resting on a floor, in response to the amputee performing a rotative movement of said leg stump around its corresponding hip joint while keeping said artificial foot resting on the floor, said rotative movement at least occurring in the frontal plane of the amputee and in one rotation direction (R1) within the frontal plane, the prosthesis causes said artificial foot to rotate relative to the floor at least in the other, i.e. opposite, rotation direction (R2) within the frontal plane.

    摘要： In some embodiments of a prosthetic or orthotic ankle/foot, a prediction is made of what the walking speed will be during an upcoming step. When the predicted walking speed is slow, the characteristics of the apparatus are then modified so that less net -work that is performed during that step (as compared to when the predicted walking speed is fast). This may be implemented using one sensor from which the walking speed can be predicted, and a second sensor (66) from which ankle torque can be determined. A controller (68) receives inputs from those sensors, and controls a motor's torque so that the torque for slow walking speeds is lower than the torque for fast walking speeds. This reduces the work performed by the actuator over a gait cycle and the peak actuator power delivered during the gait cycle. In some embodiments, a series elastic element (58) is connected in series with a motor (56) that can drive the ankle, and at least one sensor is provided with an output from which a deflection of the series elastic element can be determined. A controller determines a desired torque based on the output, and controls the motor's torque based on the determined desired torque.
