A system that wirelessly integrates actual sports equipment with a computer and the internet to allow players remotely located from one another to play a competitive simulated sports game. An individual player may opt to play solo or practice to improve basic techniques. The system includes motion sensors connected to the player and a motion sensing device, all containing circuits and contact or motion sensors coupled with signal processing and radio frequency transmitter circuitry, thereby wirelessly communicate game performance information to a remote receiver-computer. The computer displays player information and visually simulates and controls a game between two players via the internet, having similar equipment and remotely located from each other. Standard sports equipment may be retrofitted with the sensors and associated circuitry to convert such equipment into “smart equipment” for use with the system. The system employs specially developed computer software to process player performance data, control game play, communicate game information between players, generate and control visual simulations and display player performance information.

A watch can include a wrist strap, memory, an accelerometer, and a pressure sensor that responds to muscle movement at a wrist. Various other devices, systems, methods, etc., are also disclosed.

An apparatus for developing goal scoring skills is disclosed herein. The apparatus includes a goal, and a three-dimensional structure. The three-dimensional structure is configured to replicate a human goalkeeper to improve a training experience for a user. The apparatus is useful for developing and improving goal scoring skills, and preferably, for developing and improving hockey goal scoring skills.

Described is a knob for application to the gripping end of a hollow stick. The knob comprises a rounded, oblique, cylindrical support structure, transitional shaft and tang aligned on a common longitudinal central axis. The support structure comprises a greater diameter rounded, cantle-like support and gripping structures.

Ejector devices and methods for golf putting training are provided. An ejector device can be configured for placement in a regulation golf hole. The ejector device can include a top member connected to a base by a lift mechanism. The lift mechanism is operated by a motor in response to commands received from a controller. The controller can selectively actuate the motor and cause the lift mechanism to raise the top member relative to the base, to thereby eject a golf ball from the hole. Such actuation can be in response to detecting the receipt of a selected number of golf balls in the hole. Alternatively, the ejector device can be operated in response to an actuation command entered by a user through a remote control device wirelessly connected to the ejector device.

Golf ball comprising one or more layers and/or indicia formed from a fluorescent composition comprising: a base polymer; and a colorant; wherein the colorant is a small-molecule ionic isolation lattice formed from one or more fluorescent dye and one or more cyanostar macrocycles. The one or more fluorescent dyes may include at least one dye selected from xanthenes, oxazines, styryls, cyanines, trianguleniums, or mixtures thereof. The colorant may be a dispersion of the small-molecule ionic isolation lattice in a carrier medium or a powder. In particular embodiments, at least one of the one or more layers is a cover layer and/or a coating layer.

The present inventive concept relates to a virtual golf device comprising a display part showing a virtual golf course and a virtual golf ball, and a calculation part calculating a movement of the virtual golf ball corresponding to a real golf ball on the virtual golf course when a user hits the real golf ball. The display part provides an information section showing information related to a green region with a target point. If a location of the virtual golf ball on the virtual golf course before the user hits the real golf ball is named a first location, a location of the target point is named a second location and a direction from the first location to the second location is named a first direction, the information section shows a distance between the second location and an intersection point where an imaginary line passing the target point and having a second direction perpendicular to the first direction meets a border of the green region.

A display method includes generating first analysis information related to at least one of a ball shooting direction and a ball curving form swing on the basis of a plurality of pieces of data related to a plurality of swings, output from an inertial sensor which is attached to a user or an exercise appliance swung by the user and measures the plurality of swings performed by the user, and generating a first region image on the basis of the first analysis information, in which the first region image includes a plurality of time-series region images, and the plurality of time-series region images are displayed in a coordinate system having at least two indexes as axes.

A construction kit of modular components including rigid and flexible foam bars with endcaps designed to be joined together by snap-fit connections to define three-dimensional, adult-sized playing fields which float in aquatic settings such as swimming pools. The connectivity of the modular components is characterized by manual assembly, a high resistance to separation during active play by teams of adults participating in vigorous athletic activities, and tool-assisted disassembly.
