A lacrosse training ball that is made up of a shell that defines an enclosure having an interior volume is disclosed. The shell includes a plurality of pads connected along a plurality of seams sewn with a thread having a finishing knot. The interior volume is substantially occupied by a filler that includes a mixture of a first material and a second material.

An apparatus, a system and a method protects a pitcher from being struck by a returning ball and has a container that encloses a bag of balls, a screen and/or a base that is attached to a lid. The lid is removed from the container and placed in front of the container which may provide a seating surface for the pitcher. The base has sides that define a channel in the base which receives the screen. The base may hold the screen in an upright position. Clips may fold outwardly from the base to assist the base in holding the screen. A leg extending from the base stabilizes the base on the ground. The pitcher may conduct batting practice by sitting on the container and throwing a ball around the screen toward the batter.

A sports projectile delivery system may control the operation of a launcher to cause an American football or other sports projectile to be delivered to a target location on a field. In some aspects, the system can track player movements on the field, e.g., through the use of a tracking device mounted on the player, enabling the ball etc. to be launched to a player in anticipation of where the player will go. The system may include additional customization and/or logging options, e.g., permitting a player to designate a body position (e.g., above the head or near the knees) for delivery of the ball, designate a speed or hang time for delivery, or provide player data and analytics to an online or otherwise connected database.

A variable-color region (106) of an information-presentation structure extends to an exposed surface (102) at a surface zone (112), normally appears along it as a principal color, and includes pressure-sensitive color-change structure (132) and pressure-spreading structure (242) having an internal pressure-spreading surface (244). An object (104) impacts the zone at an object-contact area (116). The pressure-spreading structure spreads pressure of the impact along a distributed-pressure area (256) of the pressure-spreading surface. A segment (142) of the pressure-sensitive color-change structure responds to the excess internal pressure along the distributed-pressure area by causing an impact-dependent portion (138) of the variable-color region to temporarily appear along a print area (118) of the zone as changed color materially different from the principal color if the excess internal pressure meets excess internal pressure criteria. The print area thereby closely matches the object-contact area in size, shape, and location.

A game stick and game are disclosed. The game stick includes a shaft with a head at one end. A channel wide enough for a game ball is defined in the head. The ball is placed in the channel and when the game stick is swung, the ball rides along the channel and is released therefrom to fly through the air. The head may be adjustable to affect the way in which the ball is thrown. The game is similar to golf except that instead of hitting the ball, the ball is thrown toward a target location at the end of a fairway. When the target location is reached, the game stick may be used as a putter to push or putt the ball to sink it into a sunken cup in the ground.

A system has footwear and a striking device. The striking device has a shaft connected to a striking surface for contacting an object. A sensor affixed to the shaft changes electrical resistance when the striking surface is swung to contact the object to in turn generate a signal reflective of the deflection of the shaft. The footwear is configured with an array of sensors that change at least one electrical characteristic upon deflection when the player is operating the striking device. The footwear is to send signals reflective of the deflection of the feet as the shaft is swung. The signals reflective of the deflection of the shaft and the footwear are sent to a cell phone, notebook, PC or the like suitably programmed to present audio and visual images of the feet positions and movement and movement of the striking device (e.g., golf club, racket).

Principal and secondary regions (106 and 108) of an information-presentation structure extend to an exposed surface (102) respectively at principal and secondary surface zones (112 and 114) variously impacted by a spherical object (104) that rebounds from the surface. The principal region normally appears along the principal zone as a principal color. An impact-dependent portion (138) of the principal region responds to the object impacting the principal zone at an object-contact area (116) by temporarily appearing along a print area (118) of the principal zone as changed color materially different from the principal color. The print area closely matches the object-contact area in size, shape, and location. The secondary region fixedly appears along the secondary zone as a secondary color. Restitution matching is provided across the two zones so that the rebound characteristics of the object are largely independent of whether it contacts the principal or secondary zone.

A variable-color region (106) of an information-presentation structure extends to an exposed surface (102) at a surface zone (112) and normally appears along it as a principal color. An impact-dependent portion (138) of the variable-color region responds to an object (104) impacting the zone at an object-contact area (116) by providing an impact signal if the impact meets threshold impact criteria. The impact signal identifies an expected location of a print area (118) in the zone. The print area meets one of plural different print-area location criteria respectively corresponding to plural changed colors materially different from the principal color. Responsive to the impact signal, a controller (702) determines which location criterion is met by the print area and provides an initiation signal at a corresponding condition. The impact-dependent portion responds to the initiation signal by temporarily appearing along the print area as the changed color for that location criterion.

According to one exemplary embodiment, an apparatus, system, method and/or computer program product may provide an electronically and programmably controlled remote virtual spectator/viewer device enabling viewer interaction with an entertainment participant in an entertainment forum via an exemplary digital video camera, digital audio microphone, speaker system, and display device system coupled via at least one communications interface to a communications network to allow a remote viewer to virtually interact with and communicate with the entertainment participant in the entertainment forum. Embodiments may include a graphical user interface configured to allow control of a digital video camera, and digital microphone in the entertainment forum, by a remote user from a remote location.
