An electronic tracking system for assisting a user in determining distances to landmarks and objects in a sporting environment includes a user tracking system for determining the location of a user, a heads up display for displaying information to the user, and a processor operable to communicate with the user tracking system and the heads up display. The heads up display is designed to be worn on the user's head, and to display an image within the user's field of view. The processor is programmed to determine a distance between the user's determined location and an object or a landmark on. This information is displayed via the heads up display as a numeric representation of the determined distance.

A device is provided for receiving projectiles and creating a pattern. The device includes a plurality of hoops arranged in parallel and configured to receive the projectiles. A two-dimensional grid could be providedacross a plurality of channels of the device, or on a display of the devicein order to display the projectiles received by the plurality of hoops. In some examples, projectiles may be received by a plurality of channels, and the pattern is created within the channels and is viewable through apertures across the channels. In other examples, sensors may be used to determine when a projectile has passed through one of the hoops, and indicators may be displayed in corresponding vertical columns of a two-dimensional grid on a display.

A pitch training device used to improve the throwing technique of balls used in sports. The device includes a core and a substantially disk-shaped body that provides immediate visual feedback as to whether the device was properly thrown. The core exhibits a density greater than the density of the body, thereby mimicking the moment of inertia of many sports balls. This, in turn, allows the user of the device to improve the training techniques used to increase spin efficiency of a ball while also helping train and improve other throwing techniques.

The two-part system includes a modified hockey puck and a set of goal units that can be mounted on a hockey goal. Within the puck are light sources, motion sensors, infrared transmitters, and a power source. Within the goal units are light sources, infrared sensors, and a microcontroller. When the goal units are mounted on the hockey goal, the infrared sensors form a detection area through which the puck must pass in order to count as a goal. The infrared transmitter of the puck and the infrared sensors of the goal units communicate with one another, and when an infrared signal is received the microcontroller triggers the light sources mounted to the goal to illuminate and indicate that a goal has been scored. Additionally, both the puck and the goal units are designed to reduce power consumption by switching between a low-energy mode or an active mode of operation.

A golf ball including a core and a cover covering the core, wherein the cover is formed from a cover resin composition containing a first base resin and a fluorescent pigment, the first base resin contains at least one resin selected from the group consisting of a polyurethane resin, an ionomer resin and a polyamide resin, the fluorescent pigment is a dispersion having a fluorescent dye dispersed in a second base resin, and the second base resin contains at least one resin selected from the group consisting of a benzoguanamine resin, an acrylic resin and a polyester resin, and a constituent member of the golf ball other than the cover does not contain a fluorescent pigment and/or a fluorescent dye.

A ball including a core, at least one layer of yarn surrounding the core, a cover assembly comprising panels joined by stitching and surrounding the at least one layer of yarn, a sensor to sense motion of the ball, a data output device carried by the ball and in communication with the sensor, and a light emitter coupled to the sensor.

A ladder ball game system that includes: an outside frame; a first rung within the outside frame; a second rung within the outside frame, wherein the outside frame, the first rung and second rung include an illumination means; a base; a solar power source connected to the base; and a plurality of bolas, where the bolas include an illumination means. The outside frame, first rung and second rung preferably include clear PVC pipes and embedded LED lights for illumination. The balls may include bioluminescent color and glowing strings as an illumination means.

A game ball configured for direct contact with a user's hands includes a cover formed of a natural leather and having an outer surface. The outer surface of the cover includes a pebbled texture. The pebbled texture includes a plurality of spaced apart pebble-like projections extending from a base region. Each of the pebble-like projections has a pebble height measured from the base region adjacent to the pebble-like projection to a top surface of the pebble-like projection. At least a first portion of the cover includes alphanumeric and/or graphical indicia applied by a laser ghosting process, and a second portion of the cover is formed without the indicia. The average pebble height of a plurality of the pebble-like projections in the first portion of the cover is at least 80 percent of the average height of a plurality of the pebble-like projections in the second portion of the cover.

A golf ball having a core of at least one layer is provided on the ball surface with a delustering particle-containing coating layer having an average surface roughness Ra of between 0.5 and 1.0. The golf ball is a matte ball that is free of luster and gloss and moreover can prevent a reduction in the ball spin rate on approach shots.

A method of manufacturing an article comprises etching an etched feature on a surface of a first polymeric sheet, and forming a fluid-filled bladder element from the first polymeric sheet, with the fluid-filled bladder element having a sealable internal cavity that retains fluid. The method includes assembling the bladder element in the article so that a first portion of the bladder element having the etched feature is exposed to view, and a second portion of the bladder element is blocked from view by the article. An article includes the bladder element with the etched feature.
