A movement activated illumination device, including a main body comprising a cube shape, a plurality of illumination units disposed on each side of the main body to turn on and illuminate a surrounding area in response to the main body being thrown, and a power button to turn off the plurality of illumination units in response to being depressed.

A light up net is provided comprising a net frame constructed by a plurality of frame members, the frame members are composed of a front portion and a rear portion and one or more lights are affixed to the rear portion of the one or more frame members, wherein the front portion acts as a protective layer. A method of employing the light up net to increase visibility for a user comprising powering the one or more lights.

An apparatus includes a training area in the form of an enclosed space in which light levels can be controlled, at least one physical element related to a task for which an individual is to be trained, and a lighting arrangement. The lighting arrangement generates a background luminance level in the training area sufficient to cause the vision system of the individual to function in the mesopic or low photopic range of vision, and the physical elements are themselves illuminated by an illumination means. The luminance level of the physical elements is greater than the background luminance level.

A ball toy having a solid, resiliently flexible body is disclosed. The body is penetrated by a bore, wherein bearing means are mounted, defining a rotational axis of the body therein. The bore has a bore closure at each end, mechanical connection means connecting each closure to the bearing means. The body is able to spin on said axis relative to the closures, when the closures are held in a pinching manner by a user. The body is made of a thermoplastic rubber of selected hardness properties, giving it excellent bouncing performance, with unpredictability of bouncing direction resulting from the spinning of the body.

A luminous safety ball including an inner glowing body and a foam sphere covering the inner glowing body is provided. The inner glowing body is not a perfect sphere, the foam sphere has a non-uniform thickness, and light emitted by the inner glowing body passes through the foam sphere and permeates through a surface of the foam sphere to form light with different brightness thereon.

A color coating solution is produced by dispersing a nano-color pigment and a metallic gloss pigment into a polymer resin, and the solution is coated and molded on a cover layer having a color similar to that of the color coating solution. Since the pigment composition is different between the cover layer and the color coating layer, internal shieldability is improved. As a result, a dark color or uneven surface of the core, mantle, or cover is not exposed, so that a surface defect rate can be reduced. Since both the nano-color pigment and the metallic gloss pigment are used in the color coating layer, the metallic gloss and the color are exhibited in a single layer. Therefore, it is possible to provide natural metallic gloss without a strange texture feeling.

A practice aid system includes: a practice aid device; a hoop sensor system, including first and second pairs of an optical transmitter and receiver, which are mountable on a rim of a basketball hoop; an intelligent ball, including an inflatable ball body, a ball control unit, a ball light source, and a ball motion and location sensor; an intelligent shoe, including a shoe body, a shoe control unit, a shoe motion and location sensor, a vibrator, and a shoe light source.

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.
