A wood-style golf club head having a variable thickness face, a plurality of linear face markings including at least one above and below face center, and face permanent indicia including at least two letters located at least partially on a face toe portion of the face, along with unique relationships to emphasize the contrast of some elements and reduce the contrast of other elements, including a significant contrast between the linear face markings and the face, and a controlled contrast between the face and the face permanent indicia.

Method of making a golf ball comprising the steps of: providing a subassembly; forming about the subassembly at least one layer comprised of a thermoset polyurethane which is prepared by mixing as the essential ingredients: (i) at least one long chain soft segment polyol and/or polyamine; (ii) at least one short chain-extending-type species; (iii) at least one isocyanate; and (iv) at least one additional chain-extending-type species; wherein essential ingredients (i) and (ii) are combined (reacted/mixed) to form a first sub-mixture; followed by combining/mixing the first sub-mixture and essential ingredient (iii) to form a prepolymer second sub-mixture; followed by combining (reacting/mixing) the prepolymer second sub-mixture with essential ingredient (iv) to form the thermoset polyurethane. Essential ingredients (ii) and (iv) may differ, or in some embodiments, are the same, although the total amount of essential ingredients (ii) included is preferably greater than the total amount of essential ingredient (iv).

Embodiments of wood-type club heads comprising one or more components are described herein. The wood-type club head comprises a first, metallic component, and a second, non-metallic component. The first component comprises the load bearing structure that forms the striking face, and portions of the crown, the heel, the toe, and the sole. The second component comprises a lightweight structure that wraps around the first component to form portions of the crown, the heel, the toe, and the sole. The first component comprises the majority of the club head mass and can receive removable weights. The two-component design allows for additional discretionary mass redistribution to improve center of gravity location and moment of inertia.

A golf system includes a striking area; a target area including a plurality of physical targets positioned at different locations relative to the striking area; and at least one sensing device for sensing one or more parameters regarding the travel of a physical golf ball. A processor is configured to: access a database including golf hole data, the golf hole data defining relative positions of a tee-off location and a pin location for a virtual golf hole; based on the one or more parameters regarding the travel of the physical golf ball struck from the striking area, update a virtual location of a virtual golf ball on the virtual golf hole; and generate signals to provide an indication of which of the plurality of physical targets represents a direction of the pin location based on the virtual location of the virtual golf ball and the locations of the physical targets.

A method includes receiving motion data of a user in an environment with respect to a plurality of instances of a first action by the user, determining a kinematic movement based on receiving the motion data, analyzing the kinematic movement using a neural network, obtaining a plurality of outcome types with respect to the first action of the user, correlating the kinematic movement with the at least one indication of the outcome type with respect to the first action, classifying an outcome of the first action as at least one of the plurality of outcome types, determining which of the kinematic movements of the user result in the at least one of the plurality of outcome types, and providing instructions to the user to alter the determined kinematic movements of the user that result in the at least one of the plurality of outcome types.

The presently disclosed subject matter includes a computerized method and system for providing a total score on a motion of a user. More specifically, the proposed technique obtain motion data, process the motion data and provide a total quality score for the motion of the user with respect to a designated target motion.

A golf system includes a plurality of striking areas, each striking areas being associated with a respective set of targets. The golf system includes at least one sensing device for sensing one or more parameters regarding the travel of a physical golf ball. A processor is configured to: access a database including golf hole data, the golf hole data defining relative positions of a tee-off location and a pin location for a virtual golf hole; based on the one or more parameters regarding the travel of the physical golf ball, update a virtual location of a virtual golf ball; generate signals to provide an indication of which of the plurality of striking areas or corresponding set of targets a next shot is to be struck from or to; and generate signals to provide an indication of which target in a set of targets represents a direction of the pin location.
