A spinal treatment system includes a traction device, an exercise device adapted for imparting curvature to the lumbar or sacral spine of a user and for manipulating the spine and intervertebral discs with decompression force, and a cushion coupled to the traction device and configured to bear against one or both of a head of the user and the thoracic spine of the user. The exercise device includes a frame for placement on the floor. A pad or inflatable bladder is carried by the top surface of the frame. A body strap attachment portion encompasses the thoracic-sacral spinal vertebrae region of the user and secures the frame to the user. The cushion includes one or more pad sections or inflatable bladder sections.

The various devices and systems herein include oropharyngeal exercise devices having a pump bulb with a bulb body having a flow restriction structure with a restricted configuration in which the flow restriction structure is configured to restrict the flow of fluid through the lumen such that the user must apply a force to increase the flow of the fluid. Other devices include containers and/or lids thereof with the bulbs attached to or integrated therein.

A portable ball practice rack that comprises an inflatable ring, an outer wall of it is arranged with an inflatable and exhaust gas-proof interface; a protective bag has the same structure as the inflatable ring, and is sleeved on an outer side of the inflatable ring; and an elastic cover arranged on an inner side of an opening of the protective bag, and fixed to the protective bag by a connecting piece. The disclosure adopts the principle of inflating the inflatable ring to increase the size, after the inflatable ring is full of air, tighten the elastic cover. When storing, just discharge the air of the inflatable ring, the extremely small volume is convenient for transportation and storage. At the same time, the matching protective bag can effectively protect the inflatable ring from friction with the ground, which enhances the explosion-proof and protective performance of the inflatable ring.

A golf swing resistance device that secures to a golf club to provide increased aerodynamic drag during a golf swing. The device includes disk-shaped plates with a through-bore in the center of the plates. The plates are secured to the golf club by passing the grip end of the golf club through the through-bore of the plates. The plates align along the golf shaft of the golf club and abut against the golf club clubhead during a golf swing. Multiple plates can be stacked along the length of the golf shaft. The plates have a larger span (or diameter) than the golf shaft thereby increasing the cross-sectional area of the golf club and thus increasing the aerodynamic drag on the golf club during a golf swing. The plates can vary in size and quantity to provide variable amounts of aerodynamic drag.

A golf club with a multi-material face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a multi-material striking face portion that is made out of a backing layer having a frontal pocket, made out of titanium, and an insert, made out of a composite material, adapted to be inserted into the frontal pocket. The frontal pocket and the insert could have complementary dovetail shaped undercut features to create a mechanical bond between these two components.

According to the present disclosure, an oral rehabilitation device includes an air bladder and a pumping member. The air bladder includes a cheek-side membrane and a teeth-side membrane, and the cheek-side membrane and the teeth-side membrane are arranged opposite to each other. The pumping member is communicated with the air bladder, and the pumping member is configured for inflating the air bladder. The cheek-side membrane and the teeth-side membrane extend toward the outside of the air bladder when the pumping member is inflating the air bladder, and an extension of the cheek-side membrane is larger than an extension of the teeth-side membrane.

An apparatus for receiving one or more activity attachments including a deck having one or more openings along a long axis of the deck and between the top surface and the bottom surface of the deck. Each of the one or more openings having a circular aperture for receiving an accessory of a set of accessories. Each accessory of the set of accessories providing an activity for a user of the activity. Each accessory having an attachment platform configured to attach the accessory to the board. The attachment platform having a locking mechanism to engaging with a complementary locking mechanism of the board.

A sports ball includes sensing electronics embedded therein. The electronics are supported on an inner surface of the wall of the ball within an elastomeric boot that extends inwardly toward the center of the ball. The elastomeric boot is configured to protect the electronics from damage due to shock as the ball is used, and to have little if any effect on the performance characteristics of the ball.

The present invention is a portable resistance machine that allows a user to perform rowing, skiing, paddling, or any other physical activities at any suitable location. The portable resistance machine contains a housing, a pulley, a flywheel, a planetary gear assembly, an anchor, a retraction mechanism, and a pull cord. The housing contains a central gear support. The pulley, the flywheel, the planetary gear assembly, and the retraction mechanism are positioned within the housing. The central gear support is positioned within the housing. The planetary gear assembly is positioned within the central gear support. The pulley and the flywheel are axially connected opposite to each other along the planetary gear assembly. The retraction mechanism is operatively connected to the pulley, where the retraction mechanism is configured to retract the pull cord into a spooled state around the pulley. The anchor is externally connected to the housing.
