Systems and methods for actuating a prosthetic ankle based on a relaxed position or measured surface angle

根据放松位置或测量的表面角度致动修复踝的系统和方法

Abstract

本发明涉及用于感测致动假体踝的系统和方法。在一个示例中,所述系统例如致动的假体踝关节检测使用者已经移动到放松位置,例如就坐、后靠、慢行或斜靠。作为响应,致动的假体踝关节主动调节踝的部件之间的角度到放松状态。所述系统可以进一步检测使用者已经移动以离开放松位置的时间,并且可以主动调节踝的部件之间的角度到离开状态。在另一实施例中,所述系统例如致动的假体踝关节检测表面角度并根据上倾/下倾的相应斜度主动调节踝的部件之间的角度到优选的角度。
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. In another example, the system, such as an actuated prosthetic ankle joint, detects the surface angle and actively adjusts the members of the ankle to a preferred angle according to the respective slope of the incline/decline.
