Described herein are various embodiments of differential air pressure systems and methods of using and calibration such systems for individuals with impaired mobility. The differential air pressure systems may include an access assist device configured to help a mobility impaired user to stand in a pressure chamber configured to apply a positive pressure on a portion of the user's body in the sealed pressure chamber. The system may also include load sensors configured to measure the user's weight exerted inside and outside the chamber. The system may be calibrated by determining a relationship between the actual weight of the user and the pressure in the chamber, where the actual weight of the user may be measured by more than one load sensor and at least one load sensor is not in the pressure chamber.

A stimulation device is provided in accordance with one embodiment. The stimulation device includes a chamber which has a flexible wall portion. A drive unit of the stimulation device is in physical communication with the flexible wall portion so as to cause deflections of the flexible wall portion in opposing directions, thereby resulting in a changing volume of the chamber. The changing volume of the chamber results in modulated positive and negative pressures with respect to a reference pressure. An opening of the stimulation device is for applying the modulated positive and negative pressures to a body part. The stimulation device includes a control device for controlling the drive unit.

A display device includes a cover part, a driving unit for transmitting an external force to the human body through the cover part, and a display unit that is provided at a position of the cover part through which the external force is transmitted to the human body, and indicates a display in accordance with the external force transmitted from the driving unit.

A method for external ear canal pressure regulation to alleviate one or more symptoms associated with a disorder or treat one or more disorders, the method including providing a fluid transfer device which generates a fluid flow of a fluid through an earplug, the earplug having an earplug external surface configured to sealably engage an external ear canal wall as a barrier between an external ear canal pressure and an ambient pressure; sealably engaging the earplug of the fluid transfer device with the external ear canal wall as the barrier between the external ear canal pressure and the ambient pressure; and operating the fluid transfer device to generate the fluid flow of the fluid through the earplug to achieve an external ear canal pressure differential between the external ear canal pressure and the ambient pressure effective to alleviate a disorder symptom or treat a disorder.

An external ear canal pressure regulation device including a fluid flow generator, an earpiece having an axial earpiece bore, and a valved conduit fluidicly coupled to the fluid flow generator and the axial earpiece bore, whereby the earpiece has a compliant earpiece external surface configured to sealably engage an external ear canal as a barrier between an external ear canal pressure and an ambient pressure.

A therapeutic massage system includes a cushion and a controller unit operably connected by tubing. The cushion has a therapy pad coupled to a support pad. The support pad includes a plurality of compartments that may be filled with microbeads or other supportive material that self-adjusts to conform to the contours of an individual's body. The therapy pad includes a plurality of selectively inflatable and deflatable channels. The controller unit includes a processor operably connected to a diverter for controlling the delivery of air to and exhausting of air from the channels of the therapy pad. The massage system can be customized to provide user-specific treatment.

A flexible vibrating module with flexible radiating arms outwardly projecting around the module, with each arm having an associated coin motor which can optionally be operated at high frequency or low frequency or pulsing frequency, is shown in combination with a wrap having a snap in flexible grommet for the module to consistently orient properly the module with respect to a patient's muscles or joints.

An apparatus to treat, inhibit, or prevent an indication of a headache symptom in a patient can include a cover, sized and shaped to fit over an eye of the patient to define a cavity between the cover and an anterior surface of the eye when the cover is located over the patient eye. The apparatus can include a pressure source, in communication with the cavity, capable of applying non-ambient cavity pressure to the cavity. The apparatus can include control circuitry, in communication with the pressure source, the control circuitry storing or otherwise configured to define a target cavity pressure value specified to treat, inhibit, or prevent the headache symptom, and configured to control the pressure source to adjust the cavity pressure toward the target cavity pressure value to treat, inhibit, or prevent the headache symptom.

Disclosed embodiments provide an improved stimulation device, including a cup and a driver. The cup has a cavity surrounded by a rim. In use, a user positions the rim such that an opening to the cavity is over an area to be stimulated (for example, the clitoris). A sealed- or substantially-sealed, chamber is formed by the cavity walls and the user's skin (surrounding the clitoris). A driver is configured to vary a volume of a cavity of a cup from a first volume to a second volume. The cup returns from the second volume to the first volume, in between intermittent varying from the first volume to the second volume, due to a buckle region wall of the cup springing out. The varying of the volume creates a pressure field in the chamber. The springing out produces a “thud” force, also used interchangeably with “thump” force.
