Abstract: A non-invasive device and attendant method specifically designed to regulate and effectively equalize the pressure between the sinus cavities and middle ear, and the nasal cavity and nasopharynx. The relieving of the pressure within the sinus cavities in turn relieves pain normally associated with such a condition. The pressure equalizing assembly and method comprises establishing a seal about the nose and nostrils of the user and thereby effectively isolating the nasal cavity and nasopharynx, when the user swallows, and further establishing direct fluid communication with a vacuum chamber and a pressure regulating assembly so as to create an initial negative pressure within the nasal cavity and nasopharynx.

Abstract: A non-invasive device and attendant method specifically designed to regulate and effectively equalize the pressure between the sinus cavities and middle ear, and the nasal cavity and nasopharynx. The relieving of the pressure within the sinus cavities in turn relieves pain normally associated with such a condition. The equalizing of pressures comprises establishing a sealing engagement about the nose and nostrils of the user and thereby effectively isolating the nasal cavity and nasopharynx, when the user establishes a palate lock, and creating a negative pressure within the nasal cavity and nasopharynx by communication with a pressure regulating assembly. Fluid in the form of mucous, liquid and/or air is thereby forced from the sinus cavities, which may define a zone of relative high pressure into relatively low pressure zone of the nasal cavity and nasopharynx, thereby providing immediate relief from sinus pain while helping to relieve middle ear pressure and associated symptoms.

Abstract: A lightweight, portable non-invasive device specifically designed to regulate and effectively equalize the pressure between the sinus cavities and middle ear, and the nasal cavity and nasopharynx. The relieving of the pressure within the sinus cavities in turn relieves pain normally associated with such a condition. The subject pressure equalizing assembly has a face mask having a seal disposed about the outer periphery thereof which is specifically dimensioned and configured to surround the nose and nostrils of the user in an outwardly spaced relation thereto. This seal effectively isolates the nasal cavity and nasopharynx when the user swallow, and defines direct fluid communication with a vacuum chamber and a pressure regulating assembly serving to create an initial negative pressure within the nasal cavity and nasopharynx.

Abstract: An apparatus attachable to the legs of a swimmer and structured to aid the swimmer by facilitating the generation of increased thrust as the swimmer moves through the swimming stroke, wherein the apparatus includes a primary foil movable relative to the swimmer's leg and automatically positionable at a predetermined, substantively optimum angle of incidence relative to the direction of relative water flow to the apparatus during movement of the swimmer. An attitude control assembly is maintained in alignment with the direction of relative water flow and is cooperatively structured with the primary foil so as to maintain the primary foil in the predetermined, optimum angle of incidence which facilitates the generation of maximum thrust during the entire swimming stroke.

Abstract: An aquadynamic swim apparatus and method. A foil projects outwardly from a swimmer's lower leg, the foil having the shape of an airfoil and being adapted for a controlled angle of attack and rate of change thereof in response to forces applied by a swimmer's leg strokes. A second foil projects inwardly from the swimmer's lower leg, the foil being adapted for passive, limited inclination and declination.
