A massaging mechanism includes a driving member, an eccentric shaft, a guiding member and a pushing member. The driving member has a central shaft; the eccentric shaft is connected to the central shaft of the driving member for being driven by the driving member to rotate; the guiding member defines a guide hole. One end of the pushing member is connected to the eccentric shaft for being driven by the eccentric shaft to rotate around the central shaft, and the other end of the pushing member is slidably received in the guide hole for being driven by the eccentric shaft to extend and retract along an axial direction of the guide hole.

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.

An apparatus for minimally-invasive, including non-invasive, prevention and/or treatment of hydrocephalus and method for use of the same are disclosed. In one embodiment of the apparatus, a housing is sized for superjacent contact with a skull having a fontanel. Within the housing, a compartment includes a pressure applicator, such as a fluid-filled bladder, under the control of a pressure regulator. The pressure applicator is configured to selectively apply an external pressure to the fontanel. The compartment includes a pressure sensor configured to measure intracranial pulse pressure of the fontanel. Further, in one embodiment, the apparatus can cause pulse pressure modulation by adjusting the intracranial pulse pressure via the pressure applicator. This enables a non-invasive measurement of the pulse pressure and modulation thereof in infants, for example.

A percussive massage device includes a self-lubricating cylinder extending along a longitudinal axis. A motor shaft rotates about a central axis perpendicular to the longitudinal axis. A crank coupled to the shaft includes a pivot offset from the central axis. A reciprocation linkage is coupled between the pivot and a piston that moves longitudinally within the cylinder. An applicator head coupled to a second end of the piston has an end exposed outside the cylinder for application to a person receiving treatment. An annular gasket positioned between the cylinder and the applicator head removes lubricant from an outer surface of the piston to inhibit the lubricant from reaching the applicator head.

A machine that facilitates the performance of physical therapy exercises with or without the assistance of a physical therapist. The device allows a patient to sit upon a table, and connect the patient's body part to a cuff and pulling system. Then, via hand movements upon an article of the device cause body part flexion. Too, a patient can use the device for isometric like exercising via a series of stretch bands that attach to the cuff and table.

When controlling load torque of a drive unit on the basis of a biological signal detected from a subject's lower limb parts, adjustments are made to a hybrid ratio of voluntary control to generate running torque and a rotational speed of a crank according to the subject's intention and autonomous control to generate assisting power for the subject's pedaling motion on the basis of a rotation angle of the crank.

An individual linkage mechanism for a finger of an exoskeleton glove with sections that are interconnected with joints to enable changing their mutual angular orientation, which linkage mechanism includes a first linkage attached to the glove, a second linkage connected to the first linkage through a first joint, a third linkage connected to the second linkage through a second joint, and a fourth linkage connected to the third linkage through a third joint, wherein the fourth linkage is provided with a finger orthosis, and the second linkage, the third linkage and the fourth linkage are capable to assume a mutually parallel placement wherein the finger orthosis is adjacent to the second joint at a farthest end from the glove, and the third joint is closer to the glove than the second joint.

A harmonic vibration fitness machine includes a base, a platform, a movable plate, a first drive unit and a second drive unit. The first drive unit uses a first motor to drive two first linkages through a first transmission shaft and a reduction gear set, so that the first linkages drive a platform to move up and down. The second drive unit uses a second motor to drive to second linkages through a second transmission shaft and a reduction gear set, so that the second linkages drive the movable plate to move up and down. The movable plate will be linked with the first linkages during the operation process, so that the up and down movement of the platform can be multiplied. So, the harmonic vibration fitness machine can achieve the effect of single platform and double amplitude action.

The present concerns a wearable underactuated active robot with a couple of robotic joint adapted to correspond with to a couple of body joints in line on a limb of an user.

A percussive massage device includes an enclosure having a cylindrical bore that extends along a longitudinal axis. A motor has a rotatable shaft that rotates about a central axis perpendicular to the longitudinal axis. A crank coupled to the shaft includes a pivot, which is offset from the central axis of the shaft. A transfer bracket has a first end portion coupled to the pivot of the crank. A flexible transfer linkage has a first end coupled to a second end portion of the transfer bracket. A piston has a first end coupled to a second end of the transfer linkage. The piston is constrained to move within a cylinder along the longitudinal axis of the cylindrical bore. An applicator head has a first end coupled to a second end of the piston and has a second end exposed outside the cylindrical bore for application to a person receiving treatment.
