A golf tee holder includes a thin box having a top, a bottom and lateral open sides and a thickness based on a diameter of a golf tee. Laterally overlapping filaments (LOF) line the plurality of open sides and provide a friction retention of multiple golf tees inserted through the LOF into the thin box. Furthermore, a clip disposed on the thin box attaches it to a ball cap bill. A golf ball marker comprises a component of the thin box in some embodiments. A spring element within the thin box returns a golf tee pressed into it back out through the lateral overlapping filaments to a user of the thin box. The lateral overlapping filaments comprise one of bristles, fibers, cord, string, fuzz and tuft.

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.

Real-time sports competition is hosted by a server between remote opponents. The interactive sports game play involves sport specific tools simulating equipment used for in-person sports competition with projectiles. Opponents are paired for sports competition using the sport specific tools, including identifying opponents from the plurality of players to compete. A competitive sports game is hosted between the paired opponents by receiving input from each player sourced from a sport specific tool with sensors to determine motion of the specific sport tool caused by players, and wireless circuitry to transmit motion data to the user computers, wherein motion data includes at least velocity and impact force against a projectile. A winner of the competitive sports game can be determined.

A sports simulator calculates the rotational and translational velocity of a sports object. The rotational velocity is calculated using image analysis. The translational velocity is calculated using image analysis and a set of emitters and sensors. The simulator then computes the future trajectory of the sports object based on the rotational and translational velocity. In one embodiment, the sports object is a golf ball and the sports simulator simulates golf.

A system and method for analyzing and improving the performance of a body motion of an animal or human subject requires instrumenting a subject with inertial sensors, monitoring a body motion of interest, converting sensor data into motion data and animation, comparing the motion data with existing data for motion related performance parameters, providing a real-time, information rich, animation and data display of the results in color coded displays; and based on the results prescribing a training regime with exercises selected from a library of standardized exercises using standardized tools and training aids.

A putting trainer, as described herein, is used for practicing golfing with a golf club with a head. The putting trainer is for use on a generally smooth putting surface. The putting trainer has a body and at least one obstacle.

The invention relates to a mobile charging station for at least one ball game device, in particular in the form of a golf ball, comprising at least one internal energy source and at least one holding means for holding and fixing at least one ball game device having integrated electronics, wherein the at least one held ball game device can be charged or can be supplied with energy by the at least one internal energy source.

Provided is a sensing system, a sensor device, and a sensor fixture. The sensing system includes a sensor fixture that has a mode corresponding to an attachment attitude to a target object and a sensor device that is attachable with the attachment attitude to the target object via the sensor fixture. The sensor device includes a sensor unit that senses information regarding the target object, and an acquisition unit that acquires information indicating the attachment attitude based on the mode of the sensor fixture.

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 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.

Electronic tracking systems are disclosed for assisting users with locating objects in a sporting environment. One such system includes a ball tracking component that tracks a game ball while moving in the sporting environment, and a heads up display that is worn by the user. This heads up display has an electronic display screen with a transparent display area that dynamically displays images within the user's field of view. A processor, which communicates with the ball tracking component and heads up display, is programmed to detect movement of the game ball, and responsively determine launch characteristics and/or flight characteristics of the moving game ball. The heads up display displays the launch/flight characteristics contemporaneous with an object indication adjacent to or superimposed over the moving game ball as the game ball is visible through the transparent display area of the display screen within the user's field of view.
