    Abstract: Hybrid terrain-adaptive lower-extremity apparatus and methods that perform in a variety of different situations by detecting the terrain that is being traversed, and adapting to the detected terrain. In some embodiments, the ability to control the apparatus for each of these situations builds upon five basic capabilities: (1) determining the activity being performed; (2) dynamically controlling the characteristics of the apparatus based on the activity that is being performed; (3) dynamically driving the apparatus based on the activity that is being performed; (4) determining terrain texture irregularities (e.g., how sticky is the terrain, how slippery is the terrain, is the terrain coarse or smooth, does the terrain have any obstructions, such as rocks) and (5) a mechanical design of the apparatus that can respond to the dynamic control and dynamic drive.

    Abstract: There is provided an apparatus comprising: a flexible sheet having a hollow chamber disposed within a thickness of the flexible sheet at a localised region of the flexible sheet, and an opening for transfer of a fluid between an exterior of the flexible sheet and the hollow chamber; a fluid source configured to supply a fluid to the hollow chamber via the opening to cause an increase in at least one of the surface area or the volume of the flexible sheet at the localised region; and a control circuit for controlling the fluid source; wherein the control circuit is configured to determine a control operation by identifying a category of movement of a user and/or predicting a required change in pressure in the hollow chamber; and wherein the control circuit is configured to implement the control operation by controlling the supply of fluid to or from the hollow chamber.

    Abstract: A prosthetic knee can include a variable-torque magnetorheological (MR) actuator assembly or braking system, a frame and an electronics assembly or system that also serves as a mount for the knee actuator and facilitates in monitoring and controlling the operation of the knee actuator. The prosthetic knee system advantageously provides resistive forces to substantially simulate the position and motion of a natural knee joint during ambulation and/or other locomotory activities performed by the amputee. The prosthetic knee can be have a series of internal blades for providing resistive forces. A locking ratchet can be used to lock knee position. A dynamic seal with a protective shim can be disposed in the knee actuator. A coil with a non-circular cross-section can be used.

    Abstract: A motor and reducer structure built in a prosthetic finger includes a first phalanx having a shape corresponding to a shape from a distal phalanx to a middle phalanx of a finger and a motor built in the first phalanx. Since a motor is built in the first phalanx of the prosthetic finger, the demands of partial hand amputees of which only fingers are amputated can be satisfied. Since a reducer is built between a first joint and a second joint, the first joint and the second joint can be synchronized to perform joint movements. And since a cable operates by being disposed in contact with an outer side of a first outer circumferential surface of the first joint and an inner side of a second outer circumferential surface of the second joint positioned at an opposite side of the first outer circumferential surface, tension or shrinkage of the cable in a longitudinal direction can be prevented.
