Abstract: An aiming system that provides feedback on how closely the aim of an object is aligned with a direction to a target. An inertial sensor on the object provides data on the object's position and orientation; this data is combined with target direction information to determine how to correct the aim. An illustrative application is a golf club aiming system that measures whether the clubface normal is aligned horizontally with the direction to the hole. The system sends feedback signals to the user to help the user adjust the aim. These signals may include for example audible tones or haptic vibrations that vary in frequency and amplitude to instruct the user to adjust the aim. For example, haptic signals may be sent to a smart watch worn by the user; the user may therefore obtain aiming feedback without having to look at a screen.

Abstract: A hand-held flinging device includes a launcher that engages the projectile and improves control of the launcher and projectile, during a throwing/flinging motion, until centrifugal force causes disengagement of the projectile from the launcher. The engagement system involves the rearward portions of a launcher shaft and the projectile bore, so that, upon disengagement, frictional engagement and interference of the engagement system with the projectile is prevented or limited as the projectile moves forward to fly off the launcher. The engagement system may include a member that snaps into engagement with a hole or recess to hold the projectile on the launcher even through the wind-up portion of the throw that may include the launcher distal end being pointed downward. The preferred projectile covers the entire or nearly the entire launcher shaft distal of the hand grip and is heavier toward its front end.

Abstract: A snorkel and a mouthpiece assembly of the snorkel are disclosed, in which the mouthpiece assembly includes a main body, a mouthpiece and a whistle. The mouthpiece is connected to the main body; and the whistle has a pivoting portion and a blowing portion opposite to the pivoting portion, in which the pivoting portion is pivotally connected to the main body. The snorkel further includes a tube connected to the main body and communicating with the mouthpiece. In this way, the user can rotate the whistle against the main body for making the whistle face the mouth of the user, instead of greatly rotating the mouthpiece assembly against the tube.

Abstract: A protruding tongue and sounding structure of a puppet includes a protruding tongue and sounding device mounted inside the puppet. The puppet is a soft and hollow bag-shaped configuration. The protruding tongue and sounding device includes a housing and a slide member which is movable in the housing by air flow. A whistle is provided in the slide member. The slide member includes a tongue at one end thereof. The tongue can extend out of the slide member and the puppet. When the puppet is pressed by the user's fingers, the air in the puppet flows out through the protruding tongue and sounding device. The air in the puppet pushes the slide member of the protruding tongue and sounding device to move outward and forces the whistle to sound. Furthermore, the tongue extends outward, like the puppet to protrude its tongue.

Abstract: There is provided a whistle which suppresses any delay of sound to a listener and any attenuation of a sound volume, can transmit sound waves directly, can be blown with various tones, and has a large sound volume. Two kinds of whistles are stacked up and down and integrated together as a single whistle, an orifice is formed opposite to an air feeding opening to transmit sound waves directly to a listener. Moreover, an amount of air flowing into each air feeding tube of the whistle is controlled depending on an angle of putting a mouthpiece in a mouth to select a tone. A tone selecting member or an air amount adjusting flap is provided, and tone can be selected by mechanically blocking off each air feeding tube. Furthermore, an air amount adjusting flap which changes an air-feeding-path cross-sectional area of the air feeding opening, the air feeding tube, or the orifice is provided, and a sound volume can be changed by adjusting an amount of passing air.

Abstract: A hybrid whistle has two pealess whistle chambers with air vents to the left and right and a central pea whistle with an air vent facing generally perpendicularly to the left and right air vents that are integrally formed together, preferably in a two piece, top and bottom, construction. The hybrid whistle has a mouthpiece with a left air opening, a central air opening and a right air opening, each of which is connected to its respective whistle chamber by an air passageway. The three whistle chambers produce differing whistle pitch sounds as air flows through them and out the chambers' exits. The central pea whistle has a barrel chamber with a pea block formed within it so as to modify the barrel shape of the chamber and block the air flow as the pea circulates in the air current causing a staccato effect, while creating enough circulating air movement to prevent the pea from getting stuck in the vent by the air as it exits out of the central air exit when the whistle is blown.

Abstract: A novelty whistle for generating a sound of an animal includes a housing configured to have air blown therethrough. The housing includes a peripheral wall defining an interior space of the housing. The peripheral wall includes a front portion being substantially shaped like a head of an animal. A sound generation assembly is coupled to the housing and positioned in the interior space of the housing. The sound generation assembly produces the animal sounds when the housing is blown into.

Abstract: A whistle has a mouthpiece which is cushioned to minimize damage to the whistle and improve the comfort and safety of a user. The cushioning material is preferably injection moulded into a sleeve which locates between ridges integrally moulded with the whistle body. The body also has a plurality of projections for mating with the cushioning material. A web in an air inlet passage strengthens the mouthpiece to prevent collapse or fracture of the mouthpiece.

Abstract: A whistle is mounted to the top of a beverage bottle. The whistle can be opened for use and closed when not in use so as to be out of the way. The whistle does not prevent the user from being able to drink the beverage.

The container has a vessel for holding liquid and a spout having an entry barrel attached to an exit barrel. The entry barrel is attached at its first end to the vessel and has an opening located thereon leading to a first bore. The first bore leads to a second barrel located within the exit barrel at a T-shaped intersection. The liquid passes from the first bore into the second bore and exits via a first opening of the second bore. A second opening is located opposite the first opening to facilitate the passage of water. The second bore has a first section and a second section. A curved first shoulder is formed by the connection between the first section and the first bore. A concave recess is placed on the second bore at a location opposite the first bore.

Abstract: An amusement device for a bicycle wheel is disclosed. According to the present invention, the amusement device comprises a whistle, and a means for attaching the whistle to the wheel such that when the wheel rotates, wind passes through the whistle and produces a sound audible to a human ear. The present whistle 10 is a reversible whistle because it will produce a noise when air flows into the whistle from two different directions. The present invention is a double whistle because it funnels air from one direction into two separate whistle elements. The whistle 10 is also a double reversible whistle 10 because it can funnel air into two different whistle elements with air flowing in two different directions.
