The invention relates to a mixture of biodegradable polyesters comprising: a polyhydroxy acid of the poly-\u03b5-caprolactone type and its copolymers, aliphatic polyester, and a polymer of polylactic acid, in which the concentration of varies with respect to in the range between 40 and 70% by weight, and the concentration of with respects to lies between 2 and 30%. The module includes numerous reflective light beam deflectors which may be selected as pairs for coupling a beam of light between a pair of optical fibers. When the device is positioned a safe distance away from the user, the media is transmitted out of storage over the network to the recipient. The wireless game player may be used anywhere within the legal areas of the casino and it has the capability of identifying who is using it. With the convex edge of the bottom cover matching the curved window surface of the aquarium the magnetic brush can clean both curved window surface and the planar window surface as well.
