Abstract: Systems/techniques that facilitate automated training of machine learning classification for patient missed care opportunities or late arrivals are provided. In various embodiments, a system can access a set of annotated data candidates defined by two or more feature categories. In various aspects, the system can train a machine learning classifier on the set of annotated data candidates, thereby causing internal parameters of the machine learning classifier to become iteratively updated. In various instances, the system rank the two or more feature categories in order of classification importance, based on the iteratively updated internal parameters of the machine learning classifier. In various cases, the system can perform one or more electronic actions based on the two or more feature categories being ranked in order of classification importance.

Abstract: A hydraulic ankle assembly to be used by a user, wherein the ankle assembly includes a base configured to be attached to a spring assembly, a hydraulic cylinder rotatably attached to the base and configured to dampen rotation of the hydraulic ankle assembly, and a prosthetic adapter portion rotatably attached to the base and the hydraulic cylinder and configured to be attached to a prosthetic worn by the user. The base, the hydraulic cylinder, and the prosthetic adapter portion define a force triangle that defines an axis of rotation of the hydraulic ankle assembly. The axis of rotation is positioned in line with the center of mass of the user when the user is standing. The force triangle reduces forces on the hydraulic cylinder.

Abstract: A prosthetic foot, comprising a core, on which a proximal fastening device for fastening the prosthetic foot to a lower-leg tube or to a lower-leg shaft is arranged and which is surrounded by a foot casing. The foot casing forms a cavity, in which the core is inserted. A slot-shaped recess is formed in a front foot region of the foot casing, into which slot-shaped recess a tongue arranged on the core is inserted. The front foot region has a stiffness that deviates in comparison with the rest of the foot casing.

Abstract: A below knee amputee prosthesis liner including a molded polymer-like liner body for receiving a below knee amputation limb of a person. The liner body has a closed distal end and an open proximal end. The liner includes at least one thickening in a first region and/or in a second region. The first region is adapted to cover a head of the fibula of the amputation limb and the second region is adapted to cover a shinbone of the amputation limb, once the amputation limb is received in the liner body.
