  • SYSTEMS AND METHODS FOR ACTUATING A PROSTHETIC ANKLE
    Publication number: 20110245931
    Abstract: Systems and methods for sensing actuating a prosthetic ankle are disclosed. In one example, the system, such as an actuated prosthetic ankle joint, detects that the user has moved to a relaxed position, such as sitting, reclining, crawling, or leaning. In response, the actuated prosthetic ankle joint actively adjusts the angle between the members of the ankle to a relaxed state. The system may further detect when the user has moved to exit the relaxed position, and may actively adjust the angle between the members of the ankle to an exit state.
