Abstract: A sensor assembly for a prosthetic or orthotic device (POD) may include a housing and a support. The housing may be attached with the POD. The support may be moveably connected with the housing such that the support may move relative to the housing. The support may form an enclosure with the housing. Within the enclosure, the sensor assembly may include one or more sensors and a circuit board. The one or more sensors may include one or more of an inertial measurement unit, an electromyography sensor, or a distance sensor such as a magnetic sensor and a magnet. The circuit board may be attached with the support and in electrical communication with the plurality of sensors. Movement of the support may cause the sensors to move which may be detected for control of the POD. The sensor assembly may be attached to an arm or other prosthetic socket for detection of natural limb movements.

Abstract: Features for a prosthetic wrist and associated methods are described. The wrist couples with a prosthetic socket and a prosthetic hand. The wrist may rotate the hand. The wrist includes features to prevent or mitigate undesirable separation of the wrist from the socket. The wrist may have an expanding coupling, such as an expanding ring, to better secure the wrist with the socket. An actuator may cause the coupling to expand outward to prevent or mitigate undesirable separation of the wrist from the socket. Alternatively or in addition, the wrist may include torque control features to prevent undesirable or premature separation of the hand from the wrist, for example when using a “quick wrist disconnect” (QWD) apparatus. A torque control method may tailor or limit multiple torques to be applied by the wrist to the hand based on operational requirements and phases, such as anticipated torque loads and operational timing.

Abstract: Features for a prosthetic digit actuator. The various systems and methods allow for smaller volume actuators, which in turn allows for smaller digits and/or more space for other features of the digit. The actuator includes a motor that causes rotation of a worm gear along a fixed worm wheel. The worm gear is unibody with the output shaft. The worm gear climbs along the worm wheel to cause rotation of a digit or digit segment. The arrangement of the actuator parts allows for transmitting axial forces in first and second directions corresponding respectively to performing opening and closing rotations of the digits.

Abstract: A prosthetic hand with a waterproof cover and/or a filament-based digit securement mechanism. A first annular recess on the digit aligns with a second corresponding annular recess on a chassis to form a groove into which the filament is inserted. The prosthetic hand may comprise a waterproof cover that protects the interior components of the prosthetic hand. A thumb cover and a dorsal cover attach to a palm cover. A thumb cover interface is adhered via a clamp with an exterior sealing ring. A dorsal cover interface has a sealing ring. The thumb cover may be flexible and have three layers. The dorsal cover may be rigid and have a latch that snaps onto the chassis. The cover may be put onto the palm portion with the thumb and thumb cover, and then the prosthetic digits may be attached to the chassis thereafter.

Abstract: A prosthetic thumb having a rotation drive and articulation mechanism for causing rotation and flexion of metacarpal and phalange segments. A rotational mounting arrangement with angular contact bearing is preloaded axially. A flexion drive has a motor and gearbox adjacent and coplanar to each other, and mechanically coupled to a worm drive having a worm wheel on a second, parallel plane. A rigid linkage rotationally connects with the phalange and the worm wheel and causes flexion of the phalange segment. The thumb rotation drive rotates a metacarpal rotation wheel to cause rotation. A fixation plate supports the mechanism, such that a single structure takes all forces applied to the thumb digit, such as the plate and/or wrist, and not to a prosthetic hand structure. A potentiometer detects rotational position of the thumb digit. Some embodiments have a hollow worm gear with threaded shaft therethrough for high torque pressing states.
