A sliding mode biomimetic (bsm) controller for a prosthetic device, such as a prosthetic hand, includes an input classification component that receives electromyogram (egm) signals from two or more electromyogram (egm) sensors that are positioned on an amputee's body. The input classification component compares the egm input signals based on predetermined activation threshold values and identifies an input class to determine the amputee's intended movement of the prosthetic device.

Multiaxial joint, particularly for robotics
The present invention relates to a multi-axial joint (1), particularly for robotics. The multiaxial joint comprises a distal joint section (2) and a proximal joint section (4) that are pivotably and swivably connected relative to each other via at least one rotatory pivot joint (26) with a rotational axis (p) and at least one rotatory swivel joint (13) connected in series with the pivot joint (26) and having a swivel axis (r) extending perpendicular to the rotational axis (p).

External fixation device adaptable for bone fractures
The current request reports an external fixation device to stabilize bone fractures with adaptable configuration during different stages of surgery or during treatment, through the generation of six degrees of freedom among the bone fragments. The device comprises numerous press-connector means, numerous cylindrical bars, numerous osteosynthesis screws and optionally from one to several rigid rings and one or more extension elements that permit generating diverse stable configurations to treat bone fractures..

Expandable interbody fusion device
An expandable interbody fusion device includes superior and inferior endplates that are configured to receive a sequentially inserted stack of interlocking expansion members or wafers. The like-configured wafers include features on their top and bottom surfaces that interlock the wafers in multiple degrees of freedom so that the wafer stack is not disrupted when the fusion device is fully expanded.
