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.

An ankle-mounted sexual stimulation device and method of use enhances human sexual pleasure. The device includes a bar having a center region and a pair of terminal regions. A pair of ankle cuffs attach to the terminal regions in a freely rotating, swiveling relationship. A strap extends between the terminal regions of bar. A plate slides across length of the bar, and carries a protruding member. A pin passes through apertures in the bar and plate to fixedly fasten the protruding member at the bar. The ankle cuffs detachably attach to the ankles. A leg force applied to the ankle cuffs manipulates the bar and the protruding member in axial, rotational, and lateral directions relative to the vagina or anus. The hands grip the strap and apply a hand force to manipulate the bar and attached protruding member in axial, rotational, and lateral directions relative to the vagina or anus.

A massage chair includes a seat and a backrest configured to support a user. A pair of side panels extend upward from opposing sides of the seat so as to form an armrest. A pivoting arm is coupled to at least one of the pair of side panels and the backrest and is configured to selectively rotate between a first position and a second position. The pivoting arm extends over a portion of the massage chair in the second position and is automatically biased between the first position and the second position. A roller mechanism is included within the pivoting arm to selectively agitate a surface of the pivoting arm so as to induce a massage effect. The roller mechanism is controlled via a remote control and can operate between a plurality of settings including an on/off setting, a rotational speed setting, a motion setting, and a heat setting.

An assistance apparatus includes first to eighth wires that couple an upper body belt to be worn on an upper body of a user to a first knee belt and a second knee belt to be worn above a left knee and a right knee of the user, respectively, and a motor. In a case of assisting the user in moving to turn left, the motor generates a tension larger than or equal to a first threshold in each of the second wire, the third wire, and the fourth wire at an identical timing in a swing phase of a left leg of the user, and generates a tension larger than or equal to the first threshold in each of the fifth wire, the sixth wire, and the eighth wire at an identical timing in a swing phase of a right leg of the user.

An exoskeleton subassembly is provided. The exoskeleton subassembly includes first and second exoskeleton parts, and a connecting assembly that connects the first and second exoskeleton parts. The connecting assembly includes a guide, a pin, and a limiting device. The guide is fixedly mounted on one part, and a pin fixedly mounted on the other part and slidably mounted inside the guide. The limiting device allows rotation of the pin with respect to the guide when the pin is in a first position, and to oppose the rotation when the pin is in a second position. The limiting device includes an elastic element engaged with the first part when the pin is in the second position. The elastic element exerts on the first part an elastic return force opposing relative rotation between the first and second parts both in two opposite directions of rotation.

An apparatus that enables most common rollers to be utilized to apply shear force to a user by placing a roller into a pair of braces which each include a base support structure which is configured to receive a roller, wherein each base support structure has a rotation prevention mechanism which may be utilized to brace the roller, so that when a user applies a lateral force to the roller, the roller does not noticeably rotate. Each brace prevents rotation in one direction, so when each brace is oriented in a different direction, the roller is thereby prevented from rotating in either direction.

Several embodiments are provided of a device which is tunable for providing a walking aid user with passive haptic feedback. The haptic feedback is provided to the user when a predetermined, desired force in the device is reached. The force, often simply an axial force, in the device is inputted by the user, who is looking to support some of his or her body weight, thereby taking some weight off of one or both legs for some purpose. The amount of body weight support the user would input is often expressed in terms of percentage of the user's total body weight, and can therefore be predetermined and the device tuned accordingly.

An assistance apparatus includes first to eighth wires that couple an upper body belt to be worn on an upper body of a user to a first knee belt and a second knee belt to be worn above a left knee and a right knee of the user, respectively, and a motor. When the assistance apparatus assists the user in turning left, the motor generates a tension larger than or equal to a first threshold in each of the second wire, the fourth wire, the sixth wire, and the eighth wire. When the fourth wire or the second wire is broken, the motor changes the wire in which a tension is generated.

A scalp massager, including: a housing, a motor, a transmission assembly, and a plurality of massaging head assemblies drive by the transmission assembly. The transmission assembly includes: a worm-and-gear speed reduction assembly and a plurality of driving gears driven by the worm-and-gear speed reduction assembly and horizontally arranged inside the housing. Each of the massaging head assemblies includes: a rocker, a fixing assembly, and a massaging head. The rocker passes through the fixing assembly, an upper end of the rocker is inclinedly inserted into a corresponding driving gear, an intermediate section of the rocker is provided with a ball which is rotatably arranged inside the fixing assembly, a lower end of the rocker protrudes out of the housing, and the massaging head is fixed on the lower end of the rocker.

A portable LED-laser biomagnetic waves therapy device including a body portion, a head portion, a plurality of magnets, a plurality of LED lights, a laser and a power mechanism. The head portion is attachable to an end of the body portion. The plurality of magnets is mounted to at least one of the body portion and the head portion. The plurality of LED lights is mounted to at least one of the body portion and the head portion. The laser is mounted to at least one of the body portion and the head portion. The power mechanism is operably attached to the plurality of LED lights and the laser.
