US Patent 9568144 System for attaching a module to an object

A system for attaching a module to an object includes a module having an oblong shape, and an elastic ring. Each elongated end of the module has a recess with an interior surface formed by an upper and lower lip, and the distance between the interior surfaces of the recesses is substantially equal to the inner diameter of the elastic ring such that the module can be releasably affixed to the elastic ring. The system provides easy and reliable attachment of the module to a piece of clothing, for example.
