Abstract: Nasal cannulas for providing respiratory therapy to patients can have a curved prong section that has turbulation elements on the inside curve of the prong. A flow of breathing gas moving through the prong may incur less resistance and create less noise when flowing through such a prong due to the promotion of favorable flow dynamics.

Abstract: Noise-making devices are presented including: a compressible noise-making assembly, the compressible noise-making assembly configured for emitting a noise upon compressive deformation; a compression assembly for compressing and retaining the compressible noise-making assembly, the compression assembly including, at least two opposing surfaces defining a cavity for receiving the compressible noise-making assembly, the opposing surfaces each in mechanical communication with the compressible noise-making assembly, and at least two pulls each attached to one of the opposing surfaces such that when the two pulls are divergently pulled a compressive force is exerted upon the compressible noise-making device by the opposing surfaces.

Abstract: A portable game call ideally adapted for turkey hunting is user transformable between a variety of configurations for producing selected, game-attractive sounds. A rigid supportive hub assembly, generally in the form of a parallelepiped at least temporarily mounts the remaining parts for transportation and storage. The hub assembly comprises an upwardly projecting dome that removably gimbel mounts a ring assembly. The removable ring assembly mounts two radially spaced apart, outwardly extending strikers that can be rubbed across a frictional striking surface on the call for making "peg and slate" sounds. An outwardly extending hollow metal suction tube located between the strikers makes "wing bone" sounds. An elongated, blade-like sounding vane removably coupled to the call is slidably received within a slot in the hub. A timing cord extending between the vane and the ring enables the vane, once removed, to be spun in the air by a hunter to produce the "Pulmonic Puff" sound of the wild turkey gobble.

Abstract: A motion-activated musical device is disclosed which sounds harmonic overtones of a longitudinal resonator. Swinging the device causes the formation of a pressure differential across the device. This pressure differential causes air to flow through the longitudinal resonator, initiating an oscillation in the hole tone resonator. A standing wave is then established in the longitudinal resonator in response to this oscillation and a musical tone results. Variations in motion cause the device to sound a sequence of harmonically related musical tones.

Abstract: A toy double club with whistle including two elongate tubular bodies connected with a chain, each tubular body having a whistle in its inner cavity to move back and forth in a limited distance, the distance being by two opposing projections on the inner surface of the tubular body. A coil spring is placed between the whistle and an outer end of each of the tubular bodies so that the whistle gives out whistling sounds when moved back and forth by the swinging movement of the tubular bodies.

Abstract: A swing training device which provides both audible and tactile feedback to an individual. In one embodiment, the present invention includes a bow-shaped support structure having two tensioned laterally-displaced vibratable members positioned between the end portions of the structure. When the present invention is fixedly attached to a sports implement, such as by a clip partially encircling the shaft of a golf club, and is swung by the individual, the passage of the vibratable members through the air displaces the vibratable members which initiates their vibration. This vibration provides an audible response and a tactile response to the individual, the magnitude of which is dependent upon the velocity with which the sports implement is swung.

Abstract: An animal defensive barrier device comprising a hand-grip portion having end caps; a strap connected to the hand-grip through one of the end caps; a loop portion distal at one end of the hand-grip and a loop portion distal from the first loop end; a plurality of knots between the hand-grip and the distal loop portion; and a plurality of sleeves on the strap between the hand-grip portion and the distal loop portion.

Abstract: A toy designed for twirling or spinning by a person which not only emits a whistling sound but also includes a light emitting, replaceable unit with the light being emitted therefrom due to a chemical reaction initiated by the user. The toy is provided on a string for swinging of the same about his person with the whistling noise being emitted upon swinging of the same through the air. The unit may include reflective or attraction streamers attachable to the body of the unit and the light emitting portion of the unit is replaceable after exhaustion of the chemical reaction.
