The present disclosure relates to a cervical spine traction device, equipment and method, wherein a built-in program code determines a cervical spine stretching force according to a sensed weight of a user. The cervical spine traction device has a main controller, a fixing unit, a movable unit and thermal massage units. By storing the program code in the main controller, the optimal traction data comprising a cervical spine stretching distance, the cervical spine stretching force and a cervical spine stretching time can be calculated according to the weight and height of the user lying down on the platform. Further, by sensing the temperature of the neck of the user and massaging the neck, the tension force of the neck muscle can be relaxed, the tightness of the user can be sufficiently eliminated, and the cervical spine of the user is corrected.

A skin cleanser includes a surface, such as a silicone surface, with at least one textured portion for transmitting vibrational tapping to the skin. The skin cleanser includes at least one oscillating motor fist generating the tapping motion to the skin. The textured portion includes touch-points or a wave that transmit the tapping motion to skin in contact with the textured portions. The touch-points may include thicker and thinner formations of the touch-points to provide firmer or stiller vibrations to the skin. The touch-points are within about 0.5 to 2.5 nun in diameter. One configuration includes multiple oscillating motors configured to provide different vibration frequencies at around 50-300 Hertz and operable simultaneously.

A pressure controller for a fluidic bladder has in sequence a pump, a first fluid line, a supply pressure sensor, a second fluid line, a bladder having an inlet coupled to the second fluid line, a bladder outlet coupled to a third fluid line of substantially equal length to the second fluid line, a return pressure sensor, and a fourth fluid line coupled to the return pressure sensor and returning fluid from the pump to the reservoir. A pressure estimate is formed by averaging the supply pressure and return pressure. The pressure controller receives a setpoint pressure as a command and data over a wireless channel, and computes a head pressure offset by turning the pump off and measuring the supply and return pressures.

Methods of operating a haptic actuator to apply physical and/or thermal sensations to a user to provide subjective symptom relief to a user are described. In some embodiments, a haptic actuator may be automatically activated when one or more detected user states are compared to one or more predetermined activation parameters to determine the user is experiencing an episode related to a condition of the user. In another embodiment, one or more operating parameters of a haptic actuator may be updated if the haptic actuator did not provided a desired amount of subjective symptom relief to a user during use. In yet another embodiment, a haptic actuator may create an event log based on activation events when the haptic actuator is used to provide symptom relief for a condition of the user.

The present invention provides a handheld multifunctional facial cleansing brush structure, including a housing, a power supply assembly, a control switch, a massage assembly, a thermal conduction assembly, and a silicone sleeve. The power supply assembly, the control switch, the massage assembly, and the thermal conduction assembly are electrically connected to the power supply assembly. The thermal conduction assembly passes through an upper surface of the housing to form a thermal conduction working face. The massage assembly passes through a lower surface of the housing to form a massage working face. The housing is covered by the silicone sleeve. The present invention has a thermal conduction massage function and an LED phototherapy function and is convenient to use. In addition, a surrounding design of massage bumps better fits with the face and provides a more comfortable massage.
