An assist device includes a first harness, a second harness, a belt body, an actuator and a controller. The controller is configured to perform operation control of the actuator. The controller is configured to, upon operation of the actuator being started in a state in which the first harness and the second harness is fitted to the user, perform winding of the belt body with a first winding force, and is configured to, upon the winding of the belt body being completed, change the winding force of the actuator to a second winding force that is smaller than the first winding force.

A percussive therapy device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, and a push rod assembly operatively connected to the motor and configured to reciprocate in response to activation of the motor. The percussive therapy device includes at least one of a thermal sensor, a heart rate monitor or a heated massage member.

A portable device for massage provides both massage through vibration and oil rubbing. The device mainly includes a gear mounting plate along with shafts, motor, motor gear, cycle gear, first bevel gear, bracket along with actuator and quarter pin joint, second bevel gear, vibrating plate along with vibrating knobs, oil rubbing plate, crank pin and bearing. This device is operated on DC current which makes it suitable for usage in vehicles. This device provides relief through vibration and oil rubbing at any part of body based on inception of pain.

A training device suppresses unintended operation of an operation rod when executing an operation mode in which operation of the operation rod is controlled based on a force applied to the operation rod. The training device includes the operation rod, a motor, a force detector, a rotation information output sensor, a first command calculator, and a force corrector. The operation rod moves a limb. The motor operates the operation rod in a direction of degree of freedom. The force detector detects a force component and outputs a force component signal. The rotation information output sensor detects an operation position of the operation rod in a corresponding direction of degree of freedom. The force corrector calculates a corrected force component value based on operation positions of the operation rod and force component signal. The first command calculator calculates a first motor control command based on the corrected force component value.

Two groups of massage heads are arranged on a main body of the movement, each massage head group includes a first massage head and a second massage head, the movement body includes the motor, the worm on the motor driven at both ends of the turbine, each turbine transmission including a kneading gear with a shaft, the first massage head is arranged at the end of one connecting arm, the other end of the connecting arm is arranged on the shaft, and a connecting arm. The distance between two nodules and a third nodule of each of the two groups of massage heads emulates a human thumb and fingers; a cover coupled to the main body including at least two adjustable straps configured to accept human arms; and a buckle coupled to the at least two adjustable straps to enable lengthening and shortening of the at least two adjustable straps.

A massage mechanism and its massager. The massage mechanism includes a base, motor, drive assembly, first drive shaft, first bearing, first massage drive assembly, first massage head assembly, inter-shaft drive assembly, second transmission shaft, second bearing, second massage drive assembly and second massage head. There is also provided a massager including the foregoing massage mechanism. The mechanism could optimize those unstable and noisy features for an ideal massage experience, and solve the problem that multiple massage actions cannot be driven by a single motor.

Systems and methods for an improved walker are provided. The inventive walker allows for greater control over the speed of the walker. More specifically, wheels having specific characteristics may be used to control the speed of rotation of the wheels. For instance, the wheel may include an inner wheel assembly including a coil or coils, and an outer wheel assembly including a magnet or magnets. A magnetic field may be created using current through the coils, which in turn limits the speed with which the outer wheel assembly can be rotated relative to the inner wheel assembly. The present invention also includes a control system used to control the speed and other characteristics of the walker. The present invention may also collect associated data and display of the same which can help determine future activities associated with the walker.

A beauty apparatus includes a main body having a gripper and a head attached to one end of the main body. A circular opening from which foam is discharged is provided in the head, and spherical rollers are provided on at least one shaft extending in a circumferential direction of the opening.

A therapeutic device that surrounds and firmly grips the upper part of the arm and which allows the therapist to apply a pair of opposing tangential forces (13) to the protrusions or protuberances (6) and (7) of the device in order to perform passive internal and external shoulder rotation exercises without transmitting any force to the elbow. This means of applying forces directly to the upper part of the arm prevents the forearm from having to be used as a lever to perform rotations, which can damage or affect the elbow during the therapeutic process. In addition, the device allows the greatest possible force to be applied to the shoulder to maximize recovery. The alternative design of the device allows a variable speed motor to be coupled by incorporation of coupling parts (14), (15).

An intelligent rechargeable battery pack having a battery management system for monitoring and controlling the charging and discharging of the battery pack is described. The battery management system includes primary and secondary protection circuits for monitoring the charging and discharging of the battery. Individual battery cells forming the battery pack are connected by a main bus to a connector for connection to a battery charger or a device to be powered, and the main bus may be interrupted by a switch controlled by the battery management system to prevent damage to the battery during charging or discharging of the battery.
