A method of relieving a hyperirritable area on or surrounding a mandible. The method may include steps of selecting a first head component from a set of head components of a myofascial release apparatus (MRA); connecting the first head component with a handle of the MRA; locating the hyperirritable area on or surrounding the mandible of a patient experiencing muscle tension; contacting the hyperirritable area, via a contact member of the first head component, on or surrounding the mandible of the patient; actuating a motor of the MRA, via an electrical control assembly of the MRA, from an OFF state to an ON state for vibrating the first head component at at least one predetermined frequency; and relieving the hyperirritable area on or surrounding the mandible. Optional steps may be included when using other head components provided in the set of head components.

A rechargeable therapeutic system for treating conditions of a user's nasal cavities, sinuses or ear canals includes a therapeutic device having a housing that includes an inlet that allows air to enter the therapeutic device. An acoustic vibrator located within the housing provides an acoustic vibration to the user, and a power supply located within the housing provides power to the acoustic vibrator.

The mask further includes a diaphragm and a nasal cavity in which the user's nose is located when the mask is applied around the nose of the user. A recharging station is configured to provide a charging current to the power supply.

A passively balanced load-adaptive upper limb exoskeleton. An upper arm (A), an elbow (B), a forearm (C), and a hand (D) are arranged sequentially from left to right. An upper arm upper rod (A1) and an upper arm lower rod (A2) each are hinge-connected to an upper arm elbow housing via a bearing. A forearm upper rod (C1) and a forearm lower rod (C2) each are hinge-connected to a forearm elbow housing via a bearing. An upper arm support rod (E) is disposed between an upper arm driving mechanism (A4) and an upper arm elbow assembly (B1). One end of the upper arm support rod is fixedly connected to two upper arm support rod slide blocks (9) in the upper arm driving mechanism, and the other end thereof is hinge-connected to protruding shafts on two sides of an upper arm lead screw nut connection member via bearings. A forearm-upper arm support rod is disposed between a forearm driving mechanism (C4) and a forearm elbow assembly (B2). One end of the forearm-upper arm support rod (K) is fixedly connected to two upper arm support rod slide blocks in the forearm driving mechanism, and the other end thereof is hinge-connected to protruding shafts on two sides of a forearm lead screw nut connection member via bearings. The hand is hinge-connected to a wrist. The upper limb exoskeleton of the invention is used to facilitate handling of heavy goods or carrying of certain items.

A hand-held massage device includes a housing, a first turning plate, a second turning plate, an output rod, and a driving assembly. The housing includes an opening. The first turning plate is accommodated in the housing. The first turning plate has a concave-convex surface. The second turning plate is disposed between the opening and the first turning plate. The output rod is inserted in the second turning plate and rotated with the second turning plate. One end of the output rod is inserted to the opening and another end is abutted to the concave-convex surface. The driving assembly is connected to the first turning plate and the second turning plate. The driving assembly drives the first turning plate to rotate, drives the second turning plate to rotate or simultaneously drives the first turning plate and the second turning plate to rotate.

A robotic exoskeleton comprising a back portion providing at least two degrees of freedom, two shoulder portions, each shoulder portion providing at least five degrees of freedom, two elbow portions, each elbow portion providing at least one degree of freedom, and two forearm portions, each forearm portion providing at least one degree of freedom. Associated robotic forearm joints and robotic shoulder joints are also addressed.

A joint actuator assembly incudes 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 includes a magnetic/electrical coupling comprising a magnetic coupling component configured to magnetically couple with an opposing magnetic coupling of the driven component, and an electrical element configured to provide an electrical connection to an opposing electrical element of the driven component. The actuator and driven component may be combined into a mobility device including a magnetic/electrical coupling system comprising a first magnetic/electrical coupling on the actuator assembly that magnetically and electrically couples to a second magnetic/electrical coupling on the driven component. The magnetic coupling system includes a plurality of magnetic elements located on the first and/or second magnetic/electrical couplings and opposing electrical elements for electrical connection when the actuator assembly and the driven component are joined together.

A joint actuator assembly for a legged mobility device includes a motor that drives a joint connector for driving a joint of the mobility device, and a three-stage transmission of speed reduction to result in a high torque, low speed output. The first stage may include a small sprocket mechanically connected to the output shaft of the motor, and a large sprocket driven by a cable chain to provide the first speed reduction. The second stage may include a small central helical gear mechanically connected to the first stage output, and two opposing larger first and second outer helical gears that mesh with the central gear to provide the second speed reduction. The third stage may include a cable reel assembly including an output reel and a cable element that interconnects the output of the second stage and the output reel to provide the third speed reduction.

A robotic exoskeleton comprising a back portion providing at least two degrees of freedom, two shoulder portions, each shoulder portion providing at least five degrees of freedom, two elbow portions, each elbow portion providing at least one degree of freedom, and two forearm portions, each forearm portion providing at least one degree of freedom. Associated robotic forearm joints and robotic shoulder joints are also addressed.

A massage chair includes a back massage system and a thigh massage system with a roller mechanism configured to move a roller in a three dimensional orbital motion. The roller mechanism is driven by a single motor that can change the direction in operation. Also included is a roller motion drive element within the roller mechanism. A shaft is configured to pass through the roller motion drive element in an offset non-perpendicular angle relative to the end face thereby forming an angle between the shaft and the end face that is less than 85 degrees. The offset causes the orbital motion of the roller when rotated. The electronics of the massage chair facilitate facial recognition and a medical assessment device to detect bodily characteristics. The backrest of the massage chair can elongate to stretch the user. A plurality of airbags are also available for the twisting of the user.

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.
