The present invention, in some embodiments thereof, relates to sport's equipment comprising of “thin film” and “flexible electronics” that mimic and conform to the assembly components of traditional, non-interactive, sport's equipment. The layers of the equipment contain electrical and computing circuits in the form of one or more of an active mesh, active stitching, and/or active piping that mimics components otherwise made of leather, fabric, yarn or other non-conductive materials of a sport's equipment. Further provided for is the use of a suitable wireless technology to transmit the data collected by the digitally active implements to an external computer, which is capable of receiving the data to perform a simulation or computation for a sporting exercise.

An antagonistic throwing game apparatus comprises a support, a throwing net installed on the support, and an accessory ball, wherein the accessory ball is coated with Velcro so that the ball can be adhered to the throwing net by throwing; the periphery of the throwing net is provided with an edging; an upper part of the edging is provided with a through hole, through which a guide rope passes; a free end of the guide rope is detachably connected with a locating element, wherein the support comprises a main frame body passing through the edging, and a lower end of the main frame body is detachably connected with two joints which are fixedly connected via a plurality of connecting rods with ball-tipped plungers. Ends of the joints remote from the connecting rods are detachably connected with two supporting rods. The existing throwing game apparatuses have problems such as poor stability, inconvenient disassembly and assembly. In this solution, the throwing game apparatus is provided with a guide rope and a locating element, so that the overall stability of the throwing game apparatus is enhanced, and it is convenient for practical use. The throwing game apparatus can be conveniently stored and carried through the detachably connected support.

The present invention relates generally to a novelty golf ball that has a plurality of internal electrical components capable of storing and playing a sound recording when motion of the novelty golf ball is detected. The body of the novelty golf ball may be of unitary construction or comprised of two separate halves that may be removably attached to one another to allow a user to access the electrical components stored on the interior of the novelty golf ball.

A wireless power-feeding apparatus that enables efficient wireless feeding to a power-receiving coil embedded at the center of a spherical power-receiving device. The apparatus includes: a holding member for holding the power-receiving device; a power-transmitting coil; a driver circuit for supplying the power-transmitting coil with high-frequency current to generate a magnetic flux for wireless power-feeding to the power-receiving coil; and a wireless data receiver for receiving data transmitted regularly from a wireless data transmitter, the power-transmitting coil being positioned relative to the holding member in such a manner that the axes of the power-receiving coil and the power-transmitting coil are parallel to each other when the power-receiving device is held by the holding member in such a manner that a mark provided on the surface of the power-receiving device faces a predetermined direction.

Disclosure of the present invention relates to an inverse “L” shaped tennis practice stand or device, which is installed on ground and is considerably higher than a person's height or to a wall-mountable tennis practice device, which is installed via bracket installed at a certain point at a house or building structure. In the tennis practice device according to the present invention, when a trainee hits the ball with a racket (racquet), the ball flies along a circumferential orbit/trajectory with weight or stopper, which is at an end of a horizontal pole, as the center point—that is the ball flies in the skyward direction in front (forward region) of the trainee and then returns to the same circumferential orbit/curve due to gravity, and the trainee practices tennis by repeatedly hitting the ball that falls in front of the trainee.

The present disclosure provides a stress-relief folding ball, including a folding ball main body capable of extending and shrinking, wherein the folding ball main body includes a folding matrix, folding lines, folding walls, pressing spherical surfaces and an accommodating cavity; the folding matrix is arranged in a middle of the folding ball main body, the folding lines and the folding walls are arranged at left and right sides of the folding matrix, the folding lines and the folding walls are alternately connected, the pressing spherical surfaces are arranged at left and right ends of the folding ball main body. The folding ball main body provided by the present disclosure is an integrally formed structure and not easy to be damaged, thereby reducing the purchasing cost. The selected material is the non-metal elastic material, which may increase the comfort and enjoyment during use.

Training balls are presented including: a solid sphere defining a first hemisphere and a second hemisphere; a tactile feature positioned along a first surface of the first hemisphere and substantially centered with the first hemisphere; a first grooved feature positioned along a second surface of the second hemisphere, where the first grooved feature includes a first body portion and a first pair of leg portions each extending from each end of the first body portion at a first congruent angle; and a second grooved feature positioned along the second surface of the second hemisphere, where the second grooved feature includes a second body portion and a second pair of leg portions each extending from each end of the second body portion at a second congruent angle.

This present invention relates to a multifunctional leg strengthening device for users to strengthen the lower extremities. The multifunctional leg strengthening device includes a resistance band that is removably attached to an exercise ball, such that the resistance band can be easily held by the user's hand while holding the exercise ball between the calves or thighs for performing leg strengthening exercises. The innovative multifunctional leg strengthening device may comprise a rigid or flexible resistance band. Also, the band may feature a pocket to accommodate the rigid stick or rod inside the pocket. The rigid stick design helps accommodate those with decreased lower body strength, thereby ensuring the muscles can be strengthened and rehabilitated.

This disclosure relates to a game apparatus including a housing, a motion measurement arrangement and a flexible tether. The motion measurement arrangement is at least partially located within the housing and includes a multi-axis pivot member movable relative to the housing in at least two axes. The motion measurement arrangement also includes a sensor arrangement for measuring multi-axis movement of the pivot member. The flexible tether has a free end coupled to a strikable object and a proximal end coupled to the pivot member. The motion measurement arrangement is configured to measure an indication of one or more parameters of the strikable object's motion upon striking of the strikable object by a user.

A positioning system includes a golf ball and a mobile terminal. The golf ball includes a battery and a transmitter configured to operate with electric power supplied from the battery and transmit a radio signal to outside of the golf ball. The mobile terminal includes a receiver configured to receive the radio signal from the golf ball and a processor configured to measure the position of the mobile terminal, and to measure the position of the golf ball based on the strength of the radio signal received by the receiver at two or more points at which the measured position of the mobile terminal differs.
