An adjustable gripper mechanism for male masturbation devices that allows for adjustment in gripper diameter based on individual variations in the girth of penises or based on individual preferences regarding tightness. In a preferred embodiment, the adjustable gripper mechanism comprises a left tubular portion, a right tubular portion, a hinge connecting the two tubular portions on one side of the tubular shape, a screw connecting the two tubular portions on the other side of the tubular shape, and a screw adjustment mechanism allowing for adjustment of the diameter of the tubular shape by turning of the screw. In some embodiments, the screw adjustment mechanism may be motorized, such that the gripper diameter may be adjusted electronically.

A vision training device includes a main body, a lens unit, a drive motor, and a controller. The lens unit includes a plurality of lenses respectively having different diopter values and a lens holder that supports the lenses. The drive motor moves the lens holder so that one of the lenses of the lens unit is disposed on a line of sight axis. The controller controls the drive motor such that a test lens selected from the plurality of lenses is disposed on the line of sight axis and stores an accommodation time indicating a period of time in which the eye becomes in an accommodated state to the test lens.

A motion assistance apparatus includes a force transmitting frame configured to support a distal part of a user, a slider configured to slide in the force transmitting frame, and a driving frame connected to the slider and configured to slide with respect to a proximal part of the user.

The method of treating a patient addicted to pain medication or opioids has the step administering acoustic shock waves or pressure pulses to the patient. A second embodiment includes a treatment to reduce a patient's pain caused by a medical condition and/or medical procedure to reduce or eliminate the taking of addictive pain medication. The treatment has the step of administering acoustic shock waves or pressure pulses directed to an area near a source of the pain or to one or more reflexology zones or to one or more reflexology zones and to an area near the source of the pain or both to treat the medical condition or prior to the medical procedure or during the medical procedure or after the medical procedure or any combination thereof.

The treatment has the step of administering acoustic shock waves or pressure pulses directed to an area near a source of the pain or to one or more reflexology zones or to one or more reflexology zones and to an area near the source of the pain or both to treat the medical condition or prior to the medical procedure or during the medical procedure or after the medical procedure or any combination thereof.

A method of modulating glandular secretions by administering acoustic shock waves to a gland, includes the steps of activating acoustic shock waves of an acoustic shock wave generator to emit acoustic shock waves and subjecting the gland to acoustic shock waves stimulating the gland to have a modulated response. The modulated response is one of an adjustment in hormonal release which increases low level output, decreases high level output or stabilizes erratic output. The emitted acoustic shock waves are focused or unfocused low energy acoustic shock waves. The gland underlies the patient's skin. The shock wave generator is acoustically coupled to the patient's skin using a coupling gel or liquid. The gland is one of a testicle, ovary, pituitary gland, adrenal gland, thyroid gland, thymus, pineal gland, parathyroid, or hypothalamus. The method can be repeated one or more times.

Spa systems may be used all year round and in colder weather provide an enjoyable experience for users through the cold ambient outdoor temperature and the heated water of the spa. However, failures in respect of the water circulating pump and/or heater of the spa system either mechanically, electrically or through overall power outages mean the water in the spa system and its pipework can easily freeze if ambient conditions are cold enough leading to cracks in the spa system or pipes and hence leaks when the water thaws requiring costly repair or replacement of components or entire systems. Accordingly, a freeze protection system is provided that uses a backup thermal management system discretely or in combination with other backup systems. These freeze protection systems offering backup when mechanical failures, electrical failures etc. arise by providing thermal input to the spa system through alternate thermal paths and providing alarms.

A treatment method to reduce or eliminate a patient's symptoms caused by a medical condition or disease is disclosed. The treatment has the step of administering acoustic shock waves directed to one or more reflexology zones or to one or more reflexology zones and an area near a source of the pain if any is exhibited to treat the medical condition. The treatment further has the steps of activating acoustic shock waves of an acoustic shock wave generator to emit acoustic shock waves and subjecting the one or more reflexology zones or the one or more reflexology zones and the area near a source of the medical condition or pain, if any is exhibited, to acoustic shock waves to treat the medical condition.

A pneumatically-actuated soft robotics-based variable stiffness haptic interface device for rehabilitation of a hand includes a body having a flexible outer wall and a cavity defined by the outer wall, the outer wall including a plurality of grooves configured to receive a fiber wound around the outer wall. The device further includes a pneumatic actuator in communication with the cavity and configured to provide pressure to the cavity.
