Abstract: Embodiments are directed to a prosthetic finger that includes a track that couples to a hand, a first phalange coupled to the track at a first joint, a second phalange coupled to the first phalange at a second joint, a third phalange coupled to the second phalange at a third joint, and a motor positioned at least partially within the second phalange. The prosthetic finger can include a first linkage positioned within the first phalange and configured to cause the first phalange to move relative to the knuckle in response to a motor output and cause the second phalange to move relative to the first phalange in response to the motor output. The prosthetic finger can include a second linkage coupling the third phalange to the second phalange and configured to cause the third phalange to move relative to the second phalange in response to the motor output.

Abstract: Embodiments include a prosthetic thumb device that includes a track configured to attach to a prosthetic socket, a carriage, and a locking mechanism. The carriage can include a first component that couples to the track such that the carriage is operable to move along the track, and a second component that is configured to couple with a prosthetic digit and operable to rotate with respect to the first component. The locking mechanism can be coupled to the carriage and configured such that, in a first state, it prevents the carriage from moving along the track in a first direction and, in a second state, it allows the carriage to move along the track in the first direction. Embodiments can also include the track having a curved profile, and the carriage is operable to move along the curved profile of the track.

Abstract: Various embodiments of the present invention generally relate to prosthetic partial finger designs that can mimic the last two joints of the finger. Some embodiments include a proximal phalange, a distal phalange coupled to the proximal phalange, and a knuckle track (e.g., formed in an arc). The knuckle track can be moveably coupled to the proximal phalange an may include multiple teeth formed on which the proximal phalange slides along. A ratcheting mechanism can contact the multiple teeth to allow sliding in only a first direction while the ratcheting mechanism is engaged. Some embodiments include a release mechanism (e.g., a button) configured to disengage the ratcheting mechanism from the multiple teeth to allow the distal phalange to slide in a second direction. In some embodiments, the device may include a spring-back capability that automatically extends the finger after reaching full finger flexion, enabling one-handed use.

Abstract: A miniturized laminar gear box possessing high torque densities and methods of manufacturing the same. The high torque density is possible by directing the output shaft of the planetary stages through the sun gear and behind the input shaft. This allows the input shafts of the planetary stages to face towards the interior of the gearbox and provides a rotary shaft for the spur stages housed in between the planetary stages.
