Disclosed is a golf putting correction device. The golf putting correction device of the present disclosure includes: a body formed long in one direction so as to form a straight runway on which a golf ball rolls, and having a marked line formed along the center of the straight runway; and a guide formed above the straight runway, and having a through-hole formed to be parallel with the marked line, wherein a putting posture is corrected by a putting practice while observing the marked line through the through-hole. According to the present disclosure, it is possible to provide a golf putting correction device that can: correct an address posture such that eyes, a hole, and a golf ball are aligned on the same line; maintain the progressing direction of the golf ball to be constant even if it is repeatedly used; and provide a convenient transport and storage.

A golf alignment device for use in adjustment of golf stance and golf swing and used to train a user to properly position his/her feet (stance) and the golf club (aim, ball and club head position) when hitting a golf shot. The device includes components for measurement of distance and orientation, including the position of the shoes with respect to each other, the position and/or orientation of the golf club head of the golf club being held by the user and position of the golf ball intended to be struck by the user relative to the device. The alignment device allows determination of the aim of the user as determined by the position of his/her feet as well as the orientation of the golf club head face. A method is also provided for measurement of and adjustment of a golfer's stance and golf swing. This method can be employed in training a golfer and during golf practice.

An integrated golf club comprising standard golf club shaft and an integrated electronics system golf club head apparatus for directly measuring physical parameters of the golf club head motional acceleration swing forces and golf club head face and golf ball impact forces and further processing those measurements and transmitting the measurement data wirelessly to a user interface device. The integrated electronics system golf club head comprises several optimized assemblies that support electronic measurement, processing and wireless communication functions that are integrated with a customized golf club head shell and club face to provide a golf club head with physical properties that are substantially similar to that of a regulation play golf club head of same type. The user interface device that receives wirelessly transmitted data further processes the data and provides the golfer with useful golf swing and impact metrics in multiple different user selectable formats.

In a first aspect, a system for monitoring a swing is provided that includes (1) a swing measurement device adapted to couple to a swinging object and to output a signal indicative of a characteristic of the swinging object; (2) a wireless transmitter coupled to the swing measurement device and adapted to wirelessly transmit the signal output by the swing measurement device; and (3) a wireless device adapted to receive the wirelessly transmitted signal and to provide information regarding the swinging object based on the received signal. The wireless device is a cellular telephone or personal digital assistant (PDA). Numerous other aspects are provided.

A system and method for generating at least one golf ball recommendation for a particular golfer is disclosed herein. In one aspect, the present disclosure is directed to using a machine-learning model configured to generate at least one golf ball recommendation based on a golfer's swing.

Disclosed is a smart putter for a golf club including a putter head having a putting surface for putting a golf ball on one side thereof, a swing detecting unit that is provided in the putter head to detect a balance degree of the putter head, a communication module that is provided in the putter head to transmit balance degree data of the putter head detected by the swing detecting unit to an external device, and a control unit that stores the balance degree data of the putter head detected by the swing detecting unit and transmits the balance degree data to the communication module.

The golf swing assist apparatus 1 includes a light emitting part 10, light receiving parts 20, a determination unit 30 and an output unit 40. The light emitting part 10 configured to emit a laser beam BM1 along a boundary plane SP0 that demarcates whether a trajectory 200 of a golf club GC1 is in a set area AR1 or not. The light receiving parts 20 are located at an irradiation position P0 of the laser beam BM1 along the boundary plane SP0 and are configured to detect whether the laser beam BM1 toward the irradiation position P0 is being blocked or not. The determination unit 30 is configured to determine a swing state of a player PL1 on a basis of a detection result by the light receiving parts 20. The output unit 40 is configured to output a determination result of the swing state.

Golf training apparatus is provided including sensing means provided on, associated with and/or locatable on or with a golf club in use. At least one target means is provided that is detectable by the sensing means in use. The at least one target means is a target different to a golf ball that the golf club is to hit in use and is locatable separate to and remote from the sensing means and/or golf club in use. The golf training apparatus is arranged to detect the at least one target means and, once detected, use the detected position of the at least one target means to calibrate the sensing means, the apparatus and/or calibrate data being generated by the sensing means and/or apparatus in use.

A golf club head includes a club face with at least one impact sensor, where the sensor has a passive piezoelectric element that is integrated into the club face, the passive piezoelectric element being able to generate a signal when an impact force is applied to the club face. The golf club head has an outer surface structure including an electrically conducting material, and a radio wave antenna system capable of transmitting data collected from electronics within the golf club head.

A body part movement detection system and method, for use in training for a sport in carrying out a swing in a target direction, includes a transmitter configured to transmit signals over the course of the swing, using a form of radiation consisting of acoustic and electromagnetic, a first detector configured to receive the signals from the transmitter and to produce a first output related to a first distance of the body part to a first reference location, a controller configured to receive successive first outputs from the detector and to evaluate the successive first outputs in relation to at least one previous first output, to determine whether the body part has experienced motion having a component in the target direction by an amount in excess of a threshold, and an alert system configured to generate an alert to the user when the body part has experienced such motion.
