Systems and methods for identifying golf equipment. The system may include one or more performance tracking devices, such as an optical sensor system or a radar sensor system for tracking at least one of a golf club swing or a golf ball flight. The system also may include at least one processor and memory storing instructions that, when executed by the at least one processor, cause the system to perform a set of operations. The operations include receiving current dynamic input for a golf shot from a golfer and current static input for the golfer. The operations also include executing a trained machine-learning model based on the received current dynamic input and current static input to generate predicted golf club properties and/or predicted golf ball properties for the golfer. The predicted golf club properties and/or predicted golf ball properties are displayed on a connected display.

A golf training aid is described that stabilizes a wrist and an elbow of a golfer during a golf swing. The golf training aid includes a flexible sleeve and an elongated rigid insert. The flexible sleeve is configured to receive the wrist and the elbow of the golfer. The elongated rigid insert is secured to the flexible sleeve. The flexible sleeve keeps the rigid insert in contact with the wrist and the elbow of the golfer so as to prevent pivoting of the wrist and pivoting of the elbow.

A golf club head that is capable improving on the inertia properties of a golf club head all while also improving the Center of Gravity (CG) location is disclosed herein. More specifically, the golf club head in accordance with the present invention achieves a relative low Moment of Inertia (MOI) about the Z-axis (MOI-Z) as well as a relatively low MOI about the Shaft-axis (MOI-SA), all combined with a high MOI about the X and Y-axis (MOI-X and MOI-Y) and maintaining a consistently and relatively low CG location measured along a direction tangent to the hosel axis along the X-Y plane (CG-B). The golf club head includes a frontal portion and a rear portion, each including one or more cantilevered extensions and one or more elongate protrusions that collectively constitute a snap fit mechanism adapted to removably couple the frontal portion to the rear portion.

Methods, systems, and apparatus, including medium-encoded computer program products, for 3D flight tracking of objects include a method including determining a golf ball trajectory based on observations by sensor(s), extrapolating the trajectory backward in time, calculating distance measure(s) between the extrapolated trajectory and physical locations, estimating a systemic error for observation(s), wherein the systemic error affects observed ball positions, estimating a stochastic error associated with the observation(s), wherein the stochastic error affects an angle of a trajectory determined from observed ball positions, combining the estimated systemic and stochastic errors to form error measure(s) for the distance measure(s), identifying one of the physical locations as an origin for the golf ball when the error measure(s) satisfy a criterion, and waiting for additional observations of the golf ball by the sensor(s) when the error measure(s) do not satisfy the criterion.

Provided is a sensor device-equipped golf shoes comprising: golf shoes including a left and right pair of a first shoe and a second shoe to be worn by a golfer; and a sensor device attached to the golf shoes. The sensor device includes one or more sensor modules configured to measure sensor data pertaining to at least one of an orientation of the first shoe when the golfer takes a shot, an orientation of the second shoe when the golfer takes a shot, and a positional relationship between the first shoe and the second shoe when the golfer takes a shot.

A method of predicting the likelihood of a post T-off golf swing or consecutive swings resulting in a ball being sunk in a hole; the method utilising communication equipped cameras or communication equipped laser rangefinders at known locations to determine accurate ball lie information. Transmission of this location information in real time to a processing facility linked to a database of historical play information incorporating at least ball position information and golf course in order to calculate odds of success of the upcoming swing and/or subsequent swings.

Systems and methods for tracking a sports ball assembly in real time during a sporting event are disclosed. A structure of the sports ball assembly is also disclosed. The sports ball assembly comprises at least one electronic circuit embedded or attached to a sports ball. The sports ball assembly is in network communication with a processor via at least two receivers within a sports arena. The sports ball assembly generates and transmits UWB data packets comprising movement-related data for the sports ball assembly in real time at a predetermined rate. The at least two receivers receive the UWB data packets and transmit to the processor with time stamps. The processor is operable to determine a movement of the sports ball assembly based on the UWB data packets and the time stamps received from the at least two receivers.

A golf club head includes a club body and a resting face angle adjuster. The club body includes a crown opposite a sole, a toe end opposite a heel end, a back end opposite a face, and a hosel. The sole includes a sole surface. The resting face angle adjuster includes an adjustment member having a keel surface, and a recess formed in the sole such that a portion of the sole surface at least partially bounds the recess. The adjustment member is disposed in the recess and positionable between a first adjustment position and a second adjustment position. In the first adjustment position, the keel surface is at a first distance relative to the portion of the sole surface. In the second adjustment position, the keel surface is at a second distance relative to the portion of the sole surface not equal to the first distance in the direction.

Systems, methods and computer-readable media are provided for determining an effective altitude in relation to a moving sports object. In some examples, a method includes determining respective values for an air temperature, an air pressure, and a relative humidity of an environment of interest. Based on the determined respective values of the air temperature, the air pressure, and the relative humidity, an air density for the environment of interest is calculated to derive a first air density value. A second air density value is derived for a reference environment. An absolute value of a difference between the first and second air densities is compared against a preset comparison value and, based on the comparison being equal to or smaller than the preset comparison value, an output including an indicator of the effective altitude is generated.
