A joint actuator assembly includes a motor, a rotating driving member driven by the motor for driving a driven component, and a transmission assembly located between the motor and the rotating driving member that provides speed reduction from the motor to the rotating driving member. The rotating driving member comprises a magnetic coupling including a plurality of magnetic elements that are configured to magnetically couple with an opposing magnetic coupling of the driven component. The actuator and driven component may be combined into a mobility device including a magnetic coupling system having a first magnetic coupling on the actuator that magnetically couples to a second magnetic coupling on the driven component. The magnetic coupling system includes plurality of magnetic elements located as part of one or both of the first and second magnetic couplings. The first and second couplings have opposing mating surfaces that join together in a coupled position.

A vertical oscillation auxiliary platform, wherein a drive mechanism drives an upper cover tread board to make vertical up-and-down movements with a transmission mechanism; when the drive mechanism drives a transmission shaft rotate, the transmission shaft drives lower parts of 8-shaped bearing blocks to rotate eccentrically, and upper parts thereof move horizontally; the 8-shaped bearing blocks drive one end of triangular bearing blocks to move horizontally with horizontal transmission rods, and the triangular bearing blocks, without moving a third end, convert horizontal movements at one end to be vertical movements at another end, and drive finally the upper cover tread board to generate stable vertical oscillation, so that singularity and stability of vertical movements of the upper cover tread board can be promised, and more stable and comfortable feeling and passive exercise effects can be gained, without deteriorating the exercise effects and exercise comfort due to additional disorganized lateral movements.

A self-contained reciprocation mechanism is coupleable within an enclosure of a percussive massage device and is configured to receive an applicator head for stimulating a user's muscles. The self-contained reciprocation mechanism includes a spatial positioning bracket, a semi-cylindrical bracket, a piston, a motor, a crank, and a reciprocation linkage. The spatial positioning bracket is configured to receive the other interconnected components of the self-contained reciprocation mechanism and position said components relative to each other at close predetermined tolerances to assure that the interconnected components are properly positioned to provide consistent operating characteristics. The self-contained reciprocation mechanism is coupled within the enclosure using screws which extend through mounting tabs of the spatial positioning bracket.

The present invention discloses a system for assisting a mobility-impaired individual or a patient. The system includes a track that mounts to a ceiling or wall of a structure such as a home. The track receives a sliding mechanism. The sliding mechanism connects to a strap hanging arrangement. The strap hanging arrangement connects to a vest. The vest connects to a leg support mechanism. The mobility-impaired individual wears the vest and the leg support mechanism. The sliding mechanism includes a lift strap for adjusting the height of the strap hanging arrangement thereby allowing the mobility-impaired individual to be placed in a sitting position or standing position. The mechanically driven mechanism moves along the track allowing the mobility-impaired individual to move around the structure.
