Handheld sexual appliances are disclosed herein, providing improved stimulators for stimulation of the Grafenberg area or G-spot of the female genitalia. The appliances generally comprise an elongate body having a first span, wherein is a handle region, and a second span that is angled upwards from the first span. In the second span, embodiments for stimulating the Grafenberg area are provided, comprising one or more of a mechanical finger that oscillates in a reciprocal motion within a protuberance that protrudes from the dorsal surface of the second span. In some embodiments, one or more stimulators simulates a range of motion of the back-and-forth movement of one or more human fingers. Thereby, the G-spot stimulating embodiments may directly impinge upon the Grafenberg area when inserted into the vagina, while the precise angle and force of that interaction can also be finely adjusted.

A knocking structure of double-head fascia massager is disclosed. The knocking structure includes a motor fixed in a housing of the massager and a rotating shaft driven by the motor. The rotating shaft is arranged on both sides of an axis of the motor. Transmissions are arranged on both sides of the rotating shaft, and pistons are connected with the transmissions. The pistons are constrained to move in two nozzles of the housing. The transmissions drive the two pistons to reciprocate in a staggered manner. Two massage heads are connected to the pistons, and different massage heads reciprocate in a staggered manner. An advantage of the present disclosure is that one motor controls the simultaneous movement of the two massage heads, and two massage heads move back and forth to massage body, which speeds up the frequency of massage and increases the area.

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 safety walker provides a strap that actuates to allow a person to enter into the safety walker and then raise the strap between their legs. The strap prevents ground level falls. The safety strap is actuated by a strap actuator that may pivot about a pivot attached to the movable support frame. The strap actuator may be locked into a secure position with the strap in an elevated position by a latch. The strap actuator may be coupled to a handle actuator by one or more linkages, or the strap actuator and handle actuator may be a one-piece rigid member that rotates about a single pivot on the moveable frame. A coupling member may extend between a left and right strap actuator proximal to the back end of the strap actuators and the safety strap may be attached to the coupling member.

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.

An actuating device for orthosis includes a transmission that is operatively connected to a motor such that the motor provides power to the transmission. The transmission includes a first stage, a second stage, and a third stage. Each of these stages includes at least two sprockets and a drive belt tensioned between the two sprockets. The transmission also includes a first shaft and a second shaft. A sprocket of each of the first, second, and third stages of the transmission is attached to the first shaft. An actuating arm is operatively connected to the third stage of the transmission such that the power provided to the transmission by the motor causes the actuating arm to provide an output torque.

Methods are provided for controlling a powered lower limb device. A stance phase control method is disclosed in which the required joint torque is determined based on the difference between two joint angles, such as the knee joint and the ankle joint. A swing control method is also disclosed that employs feedback-based minimum jerk trajectory control. A joint assembly for use in a modular lower limb device is also provided. The joint assembly includes a reconfigurable slider-crank mechanism that is configurable to provide a plurality of different ranges of rotational travel, rotational speeds, and torques, for customization according to different anatomical joints. The joint assembly may include a compact coupling device for coupling a ball screw of the slider-crank mechanism to an output shaft of a motor. When employed to form a modular orthosis, the joint assembly may be adapted for self-alignment as its length adjustment method during setup.

A swinging touch massage device includes a housing and a swing member received in the housing, the swing member including a rotary motor, a reversing member and a swing rod, two opposite ends of the reversing member respectively connected with the rotary motor and the swing rod, the reversing member configured to convert a rotary motion of the rotary motor into a reciprocating swing of the swing rod; a massage protrusion is arranged at one end of the swing rod away from the reversing member, and protrudes outwardly from a surface of the housing to swing back and forth with the swing rod. The massage device provides swing touch massage and improve massage experience without being jammed.

A joint mobilization apparatus includes a pulling unit and a power unit. The pulling unit includes a wearable member set for mounting on the patient's joint part, and a rope set connected to the wearable member set. The power unit provides power of reciprocatingly pulling the rope set, and includes a shell member, a motor, and a reciprocation mechanism connected to the motor and the rope set. The reciprocation mechanism is driven by the motor to reciprocate relative to the shell member, so as to pull the rope set to reciprocate the wearable member set and patient's joint part. By using the power unit to drive the pulling unit to pull reciprocatingly for mobilizing the patient's joint part, instead of the therapist's treatment, the therapist's burden in physical strength can be reduced. Furthermore, the joint mobilization apparatus can provide the user to execute various muscle training modes.
