The present system (10) comprises a subject interface (22), a segmenter (12), a loosener (14), sensors (18), and computer processors (28). The segmenter is configured to selectively control gas flow through the subject interface to provide high amplitude pressure oscillations (44) during exhalation such that the high amplitude pressure oscillations aid cough productivity in the subject. The loosener controls gas flow through the subject interface to provide low amplitude pressure oscillations (43, 63) during inhalation (48, 68) and exhalation (49) such that the low amplitude pressure oscillations loosen respiratory secretions. The computer processors detect trigger events based on the output signals such that the one or more trigger events include a loosening trigger event and a segmenting trigger event (66); and responsive to detecting the loosening trigger event, control the loosener to provide the low amplitude pressure oscillations, and, responsive to detecting the segmenting trigger event, control the segmenter to provide the high amplitude pressure oscillations.

Disclosed herein are various embodiments of a golf club head having improved mass distribution characteristics. The golf club head includes a body and a face positioned at a forward portion of the body. The golf club head also includes one or more mass elements positioned at predetermined locations about the head. The mass elements assist in achieving a desired relationship between the moment of inertia about a center of gravity x-axis and the moment of inertia about a center of gravity z-axis.

An aqua resistance dumbbell comprises a tubular wall that provides a bore for receiving a user's hand from each end of the bell. A rod is located within the bore and extending laterally across the bore to be gripped by a user with one or both hands from one or both ends of the bore. The dumbbell has a plurality of longitudinal fins extend along the tubular wall on an outer side of the tubular wall, and at least one lateral fin that extends laterally at least part way around the tubular wall. An aqua resistance fin assembly comprises two fin components and at least one fastening member for fitting the fin components to a user's limb in a side-by-side configuration around the limb. Each fin component comprises a base adapted to fit against a user's limb and adapted to be secured to the user's limb by the fastening member, and at least two longitudinal fins and at least one lateral fin on an outer side of the base.

A sports ball outer casing comprising a ball-shape frame (4) defining a plurality of openings (6, 6a, 6b) and a plurality of panels (8), each panel being secured to the frame to cover a respective one of said plurality of openings. In this construction the frame provides a ‘skeleton’-like structure that can follow what would be the seam lines between panels in a conventional ball casing.

Golf clubs with improved aerodynamic properties. In an example, a golf club has a golf club head; a grip; and a shaft having a tip end and a butt end. The golf club head is coupled to the shaft at the tip end, and the grip is coupled to the shaft at the butt end. An average bending stiffness of a butt end portion of the shaft is greater than 3.70 times an average bending stiffness of a tip end portion of the shaft.

This disclosure relates to a drying rack for wet equipment constructed to support wet equipment having absorbent and non-absorbent sides. The drying rack supports the equipment such that absorbent sides of the wet equipment are generally oriented in a single windward direction relative to an external airflow source.

A golf club head includes a body member having a ball striking face, a crown, a toe, a heel, a sole, a rear, and a hosel region. The heel includes an airfoil-like surface shaped like the leading edge of an airfoil that extends over a majority of the length of the heel. The back may include a Kammback feature having a concavity extending from the heel-side to the toe-side of the back. The heel-side edge of the concavity may be shaped like the leading edge of an airfoil. Further, the sole may include a diffuser that extends at an angle of from approximately 10 degrees to approximately 80 degrees from a moment-of-impact trajectory direction. A hosel fairing that extends from the hosel region toward the toe may also be provided on the crown. A golf club including the golf club head is also disclosed.

A sports and games apparatus consisting of two rods and an aerodynamic projectile with an opening which receives the two rods. The projectile is launched by manipulating the rods in an opposing fashion. The opening of the projectile is of the appropriate size to allow for the rods to slide through, but not large enough that the projectile exhibits unwanted motions that inhibit accuracy during the launching motion. The rods are used to propel the projectile towards a variety of targets which interact with the projectile in various ways. The projectile may comprise a multitude of aerodynamic shapes and a multitude of methods for interacting with targets.

Embodiments of golf coupling mechanisms are presented herein. Other examples and related methods are also disclosed herein.

A ball includes a bladder and multi-layer cover. The multi-layer cover includes an outer layer and an intermediate layer between the outer layer and the bladder. The intermediate layer is formed of a plurality of perforated panels. In at least one embodiment, the plurality of perforated panels are foam panels defining an array of apertures. In at least some embodiments, the array of apertures in the intermediate layer are detectable by one or more human senses via the outer layer.
