A golf ball alignment tool (100) for assisting a golfer in visually aligning a golf ball (200) with a golf hole (114), the tool comprising a support base (101) and an alignment indicator (102), wherein the alignment indicator (102) is mounted on the support base (101) and moveable relative thereto to allow adjustment of the alignment indicator (102) without movement of the support base (101).

A golf putter training tool having a putter mounting base on top of an artificial green connected through a slot to a linear putting guide located beneath the artificial green. A golfer engages putter mounting base with a golf club, which is held in place by a friction or interference fit next to or on a sponge-like or rubber-like material. Practice shots made on the tool are constrained to be linear back-and-forth by linear putting guide. This constraint helps the golfer develop muscle memory for correctly aiming a put. Putter mounting base has an alignment guide against which the face of the golf club rests, constraining the face of the golf club square to the ball when the golfer makes the stroke. This constraint helps of golfer develop muscle memory for hitting the ball squarely. The tool has accessories such as a gravity ball feed mechanism.

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.

Embodiments herein describe a wristband for securing a smart electronic wrist device to the human subject. A heart rate sensor, coupled to the wristband of one embodiment, attaches to the human subject, and to generate electronic signals responsive to the heart rate of the human subject. An analog to digital signal converting circuit (ADC), electronically coupled to the heart rate sensor, to receive electrical signals generated by the heart rate sensor. A digital signal encoding circuit, electronically coupled to the ADC, to convert the electrical signals to data signals. A wireless communication interface to transmit the digital signals wirelessly to a handheld phone call device. The handheld cellular device includes a physiological processor for analysis of the data signals concerning the heart rate of the human subject.

A multifunctional self-contained system that wirelessly integrates actual sports equipment with a computer providing critical feedback to improve all aspects of a player's game, and also allows players to play an actual competitive real or visually simulated game or sports with one or more players. Therefore, an individual player may opt to play solo or practice to improve basic golfing skills and techniques. The system includes sport implements that include, but are not limited to, smart golf clubs, a golf ball receptacle and a golf club motion sensing device, all containing circuits with contact sensors and or motion sensors coupled with signal processing and radio frequency transmitter circuitry to wirelessly communicate game status and performance parameters to a remote receiver and computer. The computer then optionally displays important parameters such as proximity of a sports implement contact face to an object, the impact of a sports implement with a sports equipment item, wherein the contact force, contact time, impact location, face angle, spatial orientation of a sports implement in motion, and the subsequent energy, velocity, and trajectory of game projectile such as a golf ball. The sports implements can be further equipped with motion sensing devices, and its motion and swing trajectory is visually simulated on the computer display. Standard sport implements which include, but are not limited to, golf clubs may be retrofitted with the device sensors and associated electronic circuitry to convert such clubs into “smart clubs” for use with the system. The system employs specially developed computer software to process player performance data, control game play, communicate game information to players, generate and control visual simulations, and display player performance information.

A system, method and device are provided for use in golf putting training, and as golf putting training aids. The disclosed devices include particularly less-than-standard sized training balls, undersized practice balls, and smaller-than-standard diameter and/or miniature training/practice balls, constructed to have a similar weight and feel at impact as a standard-sized golf ball.

A golf ball that includes at least one core, and a cover layer formed from a cast polyurethane or polyurea, wherein the cover layer defines a first surface area portion of a uniform first color and a second surface area portion of a uniform second color, and a seam between the first surface area portion and the second surface area portion, wherein the first color is different than the second color.

Real-time sports competition is hosted by a server between remote opponents. The interactive sports game play involves sport specific tools simulating equipment used for in-person sports competition with projectiles. Opponents are paired for sports competition using the sport specific tools, including identifying opponents from the plurality of players to compete. A competitive sports game is hosted between the paired opponents by receiving input from each player sourced from a sport specific tool with sensors to determine motion of the specific sport tool caused by players, and wireless circuitry to transmit motion data to the user computers, wherein motion data includes at least velocity and impact force against a projectile. A winner of the competitive sports game can be determined.

A putting trainer, as described herein, is used for practicing golfing with a golf club with a head. The putting trainer is for use on a generally smooth putting surface. The putting trainer has a body and at least one obstacle.
