Abstract: A player apparatus for compact discs and similar signal carriers provided with a disc storage unit. The storage unit having the disc holder for holding discs arranged as an integral part of player apparatus. Storage unit arranged to store discs in a manner which allow placing stored discs parallel to the disc which is positioned into drive for playback/recording, therefore the allowing storing additional discs without significant increasing of external dimensions of the player apparatus.

Abstract: A wheel having a flexible shape rim, a plurality of resilient spokes with both ends mounted on the flexible shape rim, a plurality of hubs disposed in central part of the wheel. The hubs are mounted on an axle that attached to frame of vehicle and rotate independently. Each hub is in touch with one or more of the spokes in a manner that allows spokes motion in relation to the hub. Shifts of the spokes caused by the hubs movements and the rim distortions enforces the rim to change shape from conventional annular to the shapes such as elliptical, oval, and other similar shapes when stationary and while moving. Adjustment of the flexible rim shape caused by sudden impacts while crossing road obstructions reduces collisions of the wheel with the road obstructions, sufficiently decreasing the impact transmitted from the wheel rim to the hubs and the vehicle frame, allowing the hubs and the vehicle frame to continue movement without stress.
