The invention claims an adjustable putting aid that improves a golfer's short game by creating a visual guide for the golfer to use during their swing. The visual guide is situated higher than and out in front of the ball when the golfer is addressing the ball. During the pinnacle of the backswing, the visual guide should obscure the golf ball from the view of the golfer. The visual guide creates a path for the golfer to follow and this improves the arching in the backswing, the length of the backswing, shoulder stability and can help improve the golfer's rhythm and tempo.

A system that measures a swing of a bat with one or more sensors and analyzes sensor data to create swing quality metrics. Metrics may include for example rotational acceleration, on-plane efficiency, and body-bat connection. Rotational acceleration measures the centripetal acceleration of the bat along the bat's longitudinal axis at a point early in the rotational part of the swing; it is an indicator of the swing's power. On-plane efficiency measures how much of the bat's angular velocity occurs around the swing plane, the plane spanned by the bat and the bat's sweet spot velocity at impact. Body-bat connection measures the angle between the bat and the body tilt axis, which is estimated from the trajectory of the hand position on the bat through the swing; an ideal bat-body connection is near 90 degrees. These three swing quality metrics provide a simple and useful characterization of the swing mechanics.

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.

The present disclosure relates to systems and methods for balance index determination. For example, a wearable apparatus may have at least one gyroscope configured to measure angular velocity about a first axis; at least one inertial measurement device (IMU) configured to measure deviation along a second axis and a third axis; at least one memory storing instructions; and at least one processor configured to execute the instructions to: receive angular velocity measurements over a period of time from the at least one gyroscope; receive deviations from the second axis and from the third axis over the period of time from the at least one IMU; weight the deviations based on directions associated with the deviations; and generate a composite balance index based on the angular velocity measurements, the weighted deviations from the second axis, and the weighted deviations from the third axis.

A golf putter alignment system for viewing an orientation of a putter face relative to a putting line. A mirrored viewing surface is retained at a viewing angle by a selective, adjustable mounting system with an engaging portion, a pivot joint for angular adjustment, and a sliding joint for lateral position adjustment. The pivot joint can be a sleeve joint with an outer sleeve pivotable about a longitudinal axis relative to a core member. The sliding joint can be formed with the viewing surface slidable in relation to an elongate member, such as by being retained by a housing that is slidable in relation to the elongate member. A scope surface with an alignment scope can be retained in spaced relation to the viewing surface. In embodiments, the viewing surface can be disposed within the putter head, and a block of transparent material can have a face forming the putter face.

A pendulum stroke teaching device formed from a one piece coupling element for use with conventional golf alignment sticks and an individual's putter club. The coupling element includes two spaced apart apertures for receipt of the distal ends of the alignment sticks. A centrally disposed cavity between the apertures is constructed and arranged for receipt of a putter shaft. The coupling element operates to secure the alignment sticks and putter in a fixed position. The ends of the alignment sticks are placed between the torso and the inner upper arms of the golfer. When the golfer grasps the putter grip, movement of the putter can only take place by use of a pendulum stroke. The teaching device is used for training the golfer to use a repetitive and consistent swing for improving their golf experience.

A putting training device includes a fixing hub including a shaft retainer combined with a putter shaft; a first rotary support and a second rotary support coupled to the block part at both sides of the putter shaft, respectively; a first support bar having an upper end supposed to be held in an underarm of a user and the other end rotatably coupled to the first rotary support; a second support bar having an upper end supposed to be held in the underarm of the user and the other end rotatably coupled to the second rotary support; and an angle adjuster coupled to the first support bar and the second support bar over the first rotary support and the second rotary support to be able to adjust an angle between the first support bar and the second support bar.

A golf ball aligning device comprises a shaft having a first and a second end, a handle mounted to the first end and a head member mounted to the second end. The head member further comprises a ball opening extending through the height of the head member having a chamfered or rounded bottom edge to engage a golf ball.
