摘要:
A net apparatus arranged to provide a net structure to capture or catch a projectile, that is easy to setup and is collapsible such that the frame structure is easy to assemble by a single individual. The net apparatus comprising a base structure including at least one support portion, at least one base extension, and a hinge, wherein the at least one support portion is coupled to the at least one base extension and the hinge. At least one rod is removably coupled to the base structure and received by a net, wherein the net is adapted to exert a force on the at least one rod causing the at least one rod to exert a force onto said hinge in order to lock the at least one support portion.

Systems, apparatuses, and methods estimate the distance between a player and a ball by transmitting a chirp (sweep signal) to a radio tag located on the ball. During the chirp, the frequency of the transmitted signal is changed in a predetermined fashion. The radio tag doubles the transmitted frequency and returns the processed signal to a transceiver typically located on the player. The currently transmitted frequency is then compared with the received frequency to obtain a difference frequency from which an apparatus may estimate the distance. The apparatus may simultaneously receive the processed signal from the radio tag while transmitting the sweep signal.

Articles comprises iron oxide colloidal nanocrystals arranged within chains, wherein the chains of nanocrystals are embedded within a material used to form the article or a transfer medium used to transfer a color to the article are described. The material or transfer medium includes elastic properties that allow the nanocrystals to display a temporary color determined by the strength of an external force applied to the article, and the material or transfer medium includes memory properties that cause the displayed temporary color to dissipate when the external force is removed, wherein the dissipation of the displayed temporary color is sufficiently slow as to be visually observable by an average observer's unaided eye.

A sports apparatus for monitoring movement of a sport projectile includes a sensor and a wireless interface disposed within the sport projectile for communicating sampled data signals from the sensor, a portable communication device in wireless communication with the wireless sensor for receiving sampled data signals from the wireless sensor, the sampled data signals indicative of a motion of the sport projectile. The portable communication device includes a controller having a memory including programming instructions that when executed by the processor cause the controller to detect a sensor signal from the wireless interface, determine a motion characteristic of the sport projectile from the motion characteristic from the sensor signal, and determine if the motion characteristic is passage of the sports projectile through a goal structure, motion of the sports projectile after a shot or an impact of the sport projectile with an object.

A manufacturing method for baseball and softball includes the steps of: providing a ball core, a first ball shell, and a second ball shell, and each of the first and second ball shells being substantially in an 8-shape and having a surface and an attaching surface; sewing stitches at the periphery of the first ball shell and the periphery of the second ball shell to form a first sewing portion and a second sewing portion respectively; coating an adhesive at the ball core and coating the adhesive on the attaching surfaces of the first ball shell and the second ball shell; heating the adhesive; and positioning and attaching the first ball shell and the second ball shell on a surface of the ball core, such that the stitches of the first sewing portion and the stitches of the second sewing portion are arranged symmetrically.
摘要:
The present disclosure relates generally to an injection molded foam core composition, and a method of manufacturing the foam core. The core is made of an injection molded foam from a resin with glass temperature higher than 50° Celsius and provides improved ball performance tolerances as compared to prior art molded balls.

Kaveman Golfe Systems is a golf-like game incorporating the use of a newly designed baseball-style club in addition to newly designed golf clubs for advancing a game ball about a golf-style course. The golf and baseball hybrid game may be played using newly designed golf balls which are larger in size than a standard sized golf ball. The game may further include a newly designed baseball tee for vertically supporting the golf and baseball hybrid game ball to be struck by a player using a baseball-style swing. The clubs, balls, and tees may be stored in a specially designed golf bag.
摘要:
A glove includes a leather member formed with a first hole, and located on a catching surface side, a core material disposed inside the leather member, and formed with a second hole, and a leather string fixing the leather member and the core material. The leather string passes through the first and second holes, and goes around an end of the core material in a sectional direction, so that the leather member and the core material are fixed to each other. Hardness of the end of the core material is higher than hardness of a center of the core material. A deformation amount of at least one part of the core material located around the second hole is less than or equal to 90% of a deformation amount of the softest part located at the center of the core material.

Customized, form-fitting athletic articles with a heat moldable material that a wearer may heat to soften after purchase to conform the heat moldable material so the contours of the wearer's body may provide many advantages for consumers, such as increased comfort, performance, or safety. The heat moldable material may be incorporated into the upper of an athletic shoe. The heat moldable material may be sufficiently flexible so as not to impede the necessary movements of a wearer or the athletic shoe while performing activities, such as running, walking, jumping, etc. The heat moldable material may be reusable in that it may be reheated and remolded multiple times so that the article may be re-customized or re-fitted as needed. The article may also include a temperature sensitive indicator that indicates when the heat moldable material has been softened.
