A solution bottle contains: a body and an applying head. The body includes a holder, a first sleeve, and a second sleeve. The holder has an accommodation chamber configured to accommodate a spray can, the first sleeve is secured on a top of the holder, and the second sleeve is connected with an inner wall of the first sleeve. The second sleeve has a connection hole arranged on a bottom thereof and fitting with the spray can, and the second sleeve has a receiving groove configured to house the applying head and communicating with the fitting hole. Thereby, the solution bottle is capable of massaging and applying the solution (such as medicine agent or cosmetics) on the user's body.

A wearable device is disclosed. The wearable device may process a state variable defined based on motion information of a user, determine an interactive mode of the wearable device based on a gain associated with a magnitude of a torque of the wearable device, select a motion type from among motion types of the determined interactive mode based on a gait parameter of the user, determine a control factor for the torque based on the selected motion type, and generate the torque based on the processed state variable, the gain, and the determined control factor.

A power transmission apparatus includes a driving joint unit having a first driving gear fixed to a first driving shaft and a second driving gear fixed to a second driving shaft, an operating joint unit fixed on an operating shaft and having an operating gear rotating together with the operating shaft, a first operating belt connected to the first driving gear and the operating gear, a second operating belt connected to the second driving gear and the operating gear to apply a torque in opposite directions, a driving link having one end connected to the first driving shaft or the second driving shaft and the other end connected to the operating shaft, and an operating link fixed to the operating shaft.

A CPR chest compression system which uses tonometric data as feedback for control of chest compression device.

A vibration appliance includes a vibration-isolation structure which substantially reduces vibration felt by the user at the handle. The vibration motor is mounted to a vibration plate which carries the massage node. The vibration plate floats within the vibration appliance housing, being suspended by a flexible, elastomer membrane having contours such as curves or folds in it that provide freedom of movement of the vibration plate relative to the housing to which the flexible membrane is mounted. This arrangement can be thought of as the motor and vibration node being mounted on a flexible diaphragm that can move freely as if mounted to the housing by a bellows-like arrangement.

A massage accessory for use with an electric toothbrush has a body and a coupling mechanism. The electric toothbrush has a body, and a shaft configured to generate an oscillating movement. The coupling mechanism is configured to couple the massage accessory to the shaft of the electric toothbrush. The body of the accessory has a base at a proximal end of the body, a head at or near a distal end of the body, and a flexible region between the base and the head. The base, the head, and the flexible region are arranged such that the head is configured to move in response to the oscillating movement of the shaft and the base remains relatively stationary compared to the body of the electric toothbrush. A massage accessory for use with an electric toothbrush has a transfer shaft with a driving feature, and a coupling mechanism configured to couple the massage accessory to the shaft of the electric toothbrush. The accessory has a head having a driving feature that is complementary to the driving feature of the transfer shaft. A space is provided between the driving feature of the transfer shaft and the driving feature of the head when the transfer shaft and head are engaged such that oscillating movement of the transfer shaft causes a corresponding oscillating movement of the head and additionally causes vibration of the head.

A multifunctional massager may include a frame body, and two first connecting bases are respectively formed at two ends of the frame body at symmetrical positions. Each of the two first connecting bases comprises three connecting bears at the inner surface thereof, and the connecting bears on the two first connecting bases are located at corresponding positions. An accommodating space is formed between the two first connecting bases. A massage member installed on the fame body between the two first connecting bases comprises a driving motor, a driving shaft, two connecting rods, and two driven shafts. The driving motor is connected to and drives the driving shaft, and two eccentric wheels are connected to two ends of the driving shaft. The two eccentric wheels are adapted to eccentrically drive the two connecting rods to carry out the reciprocating actions of internal pull and external push.

An apparatus and method for use of an improved stretching device providing various stretches and manipulation of a user's muscle groups, including lower body muscle groups. Movement of the upper and lower support members can be achieved with a controller or wireless controller, such as a cellular phone executing an application operatively connected via a transceiver of the stretching device. The upper support member and lower support member may be independently controlled by a secondary motor assembly at a rotational connection between the support members. Some embodiments may provide removable support members for switching between left and right-side manipulation of a user's left and right legs with a single device. Other embodiments may include a track to allow for a sliding movement of the motor assembly or the upper and lower support members between left and right sides of the stretching device.

Provided is a walking assistance method and apparatus for providing an assistance torque to an ankle of a user. To provide an assistance torque to an ankle of a user, a first pressure value and a second pressure value are received from a first pressure sensor and a second pressure sensor, a ratio between the first pressure value and the second pressure value is calculated, a gain value is determined based on the ratio, an assistance torque value is calculated based on the ratio and the gain value, and a driver is controlled to output the assistance torque value.

A state estimation program is for causing a computer to function to determine a state of training in a rehabilitation support system used by a trainee to perform training of a preset motion and includes a threshold setting step and a state estimation step. The threshold setting step is for acquiring a sensor output, the sensor output being an output of a sensor included in the rehabilitation support system in the training performed by the trainee and setting a threshold for determining one of a normal state and an abnormal state of the training based on the sensor output. The state estimation step is for estimating whether the training is performed in the normal state or the abnormal state based on the threshold.
