A method, including scanning a golf club to obtain scanning information; inputting the scanning information into a processing system; using at least one camera positioned behind and in-line to a golf swing direction and at least one lighting unit to obtain a series of images of a golf club during the golf swing; converting the series of images into parameterized motion representations; using at least one radar to obtain a radar signal; inputting the parameterized motion representations and the radar signal into the processing system; receiving golf club parameters and golf swing parameters as an output of the processing system; and generating a visual model of the golf club and the golf swing in a virtual space using the golf club parameters and the golf swing parameters.

A golf Swing training device comprises a club member and at least one weight member. The weight member includes a mating Structure for Securing the weight member to a complementary mating Structure in the Shaft portion of the club member. The weight member can be secured to the shaft in at least three positions including a first position at the top of the Shaft adjacent the handle, a Second position at or near the midpoint of the Shaft and a third position at or near the distal end of the shaft.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

A force sensor is provided for mounting on an outside lateral surface of a golf club grip to alert a user when an excessive manual grasping force is applied to the grip during a golf swing.

A golf swing simulator/training aid includes a first rod section, a second rod section, a third rod section, a fixed weight, a grip, a first threaded connector fitting, and a second threaded connector fitting. The fixed weight is generally secured to a first end of the first rod section. The grip is generally attached to and surrounding a second end of the third rod section. The first threaded connector fitting may removably couple the first rod section to the second rod section. The second threaded connector fitting may removably couple the second rod section to the third rod section.

A golf swing training apparatus has a shaft, a housing with a top cap and a bottom cap, and a plurality of weighted discs receivable within the housing. A golfer may adjust the weight of the head of the club by adding or removing weighted discs in the housing. The golf swing training apparatus may comprise an accelerometer within the housing so as to measure the speed, acceleration, and swing path that the club takes for feedback and analysis to improve the golfer's swing.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

A swing aid is provided, comprising: a support member, having an elongated shape with a first end and a second end; a first assembly, comprising a first shell and a second shell, the first shell and the second shell being pivotally connected to the first end, the first shell and the second shell being rotatable around the first end to adjust included angles with respect to the support member, respectively; a second assembly, comprising a first indicator and a second indicator, and the first indicator and the second indicator being pivotally connected to the second end, the first indicator and the second indicator being rotatable around the second end to adjust the included angles with respect to the support member, respectively.

Various embodiments of a golf club senor housing are described herein. The sensor housing can include a cover and a base that enclose a sensor therebetween. The sensor housing can be designed to sit on the end of a grip in a position that is non-obtrusive to the user. The sensor housing can further be configured to minimizes the impact on the center of gravity (CG) of the golf club by including mass reducing features. The sensor housing is also configured to sit lower on the grip and reduce the length that it projects outward from the grip butt end. Reducing the added length from the sensor housing creates a less-obtrusive feature.

The present invention relates to a golf club reference system having improved performance in accurate hitting of a golf ball by providing the most ideal, accurate angle of a golf club at a starting point, by matching a lie angle and a socket angle when addressing. The golf club reference system of the present invention installed on a hosel installed on a club head having a hitting surface or a shaft having a handle formed in an upper portion and connected to the hosel in an lower portion, the reference system comprising: a fixing ring surrounding the hosel or the shaft, a fixing screw shaft protruding from the fixing ring in one direction; a fixing nut fixing the fixing screw shaft; a display part connected to the fixing ring through a bridge, and a color crosshair formed on an upper portion of the display part.
