Disc shaped throwing object holding a module

Abstract

A disc shaped throwing object comprises a soft disc having a central section, a bridging section and a rim, where the central section forms a disc centre through which a central axis is defined and which central section is joined to the rim via the bridging section. The disc further comprises a holding structure placed radially around the central axis, the holding structure being joined with and stretching out in a direction away from an inner surface of the central section. The holding structure is adapted to hold a module with electrically powered elements in abutment with the inner surface.
