Abstract: A method for making a piece unit of liners of American football comprises an adhering step, a cutting step, and a curing step. An extrusion-molded thermoplastic elastomer (TPE) is hot compressed molding material with a backing fabric to form a pseudo-adhesive semi-finished molding material. The semi-finished molding material is cut to be a piece unit and remain a surplus material. The piece unit is cured to form a flat piece material or a curved piece material. It may shorten the process and control the parameters and changes (such like foaming coefficient, colors, and etc.) easily. Furthermore, the strength of the ball cover may become stronger because each flat piece material or curved piece material has the arrangement of the backing fabric.

Abstract: A lighting bounce ball comprises a bouncy hollow ball body a light source, and a cover layer. One end of the ball body is communicated with a nozzle and the other end thereof opposite to the nozzle is concavely formed a cup body. The nozzle and the cup body are coaxially arranged. The light source is concavely arranged in the cup body. The cover layer covers an outer surface of the bouncy hollow ball body and the cup body so that the nozzle is partially exposed externally to the bouncy hollow ball body. The ball may be lighted while playing so as to make much funner and attract the younger to play. In addition, the track of the ball may be obviously seen in the dark or a place with insufficient light. It may be used in more adaptable places.

Abstract: A light emitting ball structure is disclosed and comprises a body; a control circuit module, disposed inside the body; at least one sensor, for detecting the motion status of the body and transmit to the control circuit module for data processing; at least one light emitting module, attached on an outer surface of the body; a wireless charge transmitting module, disposed outside the body and actuating a charging operation of a wireless charge receiving module; a rechargeable battery, electrically connected to the control circuit module, the charging operation between the wireless charge transmitting module and the wireless charge receiving module is actuating to charge; a remote control receiving module, electrically connected to the control circuit module and disposed inside the body; and a remote control transmitting module, disposed outside the body and remote controlling the remote control receiving module to process a switch ON/OFF operation.

Abstract: A method for detecting motion status of moving object structure is disclosed. The Coach controls the remote control receiving module with the remote control transmitting module to actuate the control circuit module. After the sportsman attacks the body, the Coach and/or the sportsman may see the light emitted by the light emitting module to know the motion status of the body, and detect it by the sensor and then be transmitted to control circuit module to data processing. After data processing, the message (including path, placement, height, speed, pressure, hitting point, angle, track, distance, and etc.) may be transmitted to the wireless transmission receiving module via the wireless transmission transmitting module with RF or Bluetooth and displayed on the wireless transmission receiving module to provide training. Furthermore, it may be charged by wireless charging to prevent from powering exhaustion.

Abstract: A manufacturing method for seamless manmade leather ball, wherein composites such as soft bioplastic resin or manmade leather, etc are injected, extruded or hot compressed to form upper and lower half bowl type thin covers to completely matchingly sleeve and sphere the corresponding ball bladder, next it is pressingly combined in the one step or two steps curing molds to fusionly paste with the reinforcement layer on said ball bladder to become an initial blank with waterproof layer which is further pressingly combined and cooled down to a fixed form in another set of forming molds with its outside surface formed with pre-formed lines and is further treated with a surface cortex layer and put in forming molds once again allowing surface decorative lines to be pressingly combined at second time, thereby allowing the ball to appear a better simulated leather ball outlook.

Abstract: One set of ball-giving device of hitting game, which is to improve the ball-giving mode of hitting game; top-side bushing is vertically inserted into base, supporting pipe with ball-supporting seat fixed at one end is imbedded and locked into top-side bushing, one induction eye is assembled inside ball-supporting seat, forced convection connecting with base is communicated with bushing and tube of supporting pipe via loop; basing on this structure combination, when induction electric eye induces position of ball, it then transmits the induced results to forced convection so as to start or turn off it, wind from forced convection device can blow ball into floating, so that player can hit ball easily.

Abstract: The present invention provides a kind of improved cotton-stuffed ball, which is composed of foamed or non-foamed spherical ball skin, would be formed based on a spherical empty ball model, and an air hole was designed on the spherical ball skin; in addition, a proper thin seam would be cut on the surface of ball skin as the ball line shape of the spherical ball skin, so that some cotton can be squeezed into the interior of spherical ball skin, and the thin seams would be sealed through bonding (integration closely, suturing) to form a cotton-stuffed ball of good safety. Accordingly the inflation or pressure relief of the ball would be controlled well through the air hole for function selection of higher or lower elasticity.

Abstract: An enhancing inner structure of an inflating ball with an outer layer has a round inflated inner bladder by inflating an inflatable inner bladder which is processed in advance by a separating agent. Then the inflated inner bladder is wound by fabrics to form with an enhancing layer. Then, the enhancing layer is enclosed by a plurality of piece-like structures to be as an outer layer. The fabrics are mixed with foamed soft sponge rubber. Then the outer layer is seamed. Then the whole ball structure is heated. Since the foaming material on the outer surface of the enhancing layer is non-viscous in normal temperatures, and the inner bladder is processed in advance with a separating agent; thereby, when the air in the bladder is released; the inner layer and the enhancing layer will separate naturally.
