## Abstract

A golf club comprising a golf club head having a face wall, an inertial motion unit (IMU) positioned within the body, and a transceiver in communication with the IMU, a shaft attached to the golf club head, and a grip attached to the shaft is disclosed herein. The IMU identifies an impact location with a golf ball.

## Claims

### Claim 1

A system for identifying an impact location on a golf club, the system comprising:
a golf ball having an embedded circuitry for transmitting data;
a golf club comprising
a golf club head comprising a body, an inertial motion unit (IMU) positioned within the body, and a transceiver in communication with the IMU, and
a shaft attached to the golf club head;
wherein the IMU identifies an impact location with a golf ball.

### Claim 2 (depends on 1)

The system according to claim 1 wherein the impact location is determined based on an impact signature immediately after a golf club head impact with a golf ball.

### Claim 3 (depends on 1)

The system according to claim 1 wherein the collected impact datasets are associated with impact locations.

### Claim 4 (depends on 1)

The system according to claim 1 wherein a neural network learns from these dataset and then resolves impact location from any new dataset.

### Claim 5 (depends on 1)

The system according to claim 1 wherein the golf club head mounted IMU collects impact datasets from multiple impacts of the ball at multiple locations.

### Claim 6 (depends on 1)

The system according to claim 1 wherein further comprising a neural network to identify impact location on a golf club head.

### Claim 7

A method for identifying impact location on a golf club head, the method comprising:
impacting a golf ball with a face of a golf club head of a golf club, the golf club head comprising an inertial motion unit (IMU);
transmitting data from an RFID chip embedded within the golf ball; and
identifying an impact location using the IMU and a neural network.
