Patent ID: 8531047

Claim:
An energy converter comprising: one first element and one second element; a coupling element, wherein the first element is coupled mechanically to the second element by said coupling element, wherein the coupling element is constructed both to store mechanical energy and also to output stored mechanical energy, and wherein the first element receives a movement of a medium and transmits to the coupling element; a holding element, configured to exert a predetermined retaining force and prevent a transmission of the movement to the second element until the retaining force is exceeded; wherein the coupling element outputs mechanical energy to the second element, and wherein the second element is constructed as an electromechanical converter, which converts the introduced movement energy into electrical energy; a radio transmit device or a radio transmit and receive device coupled to the energy converter, wherein said device is operated by electrical energy generated by the energy converter; and wherein the energy converter is further configured to have at least one of a magnetic retaining force; a electromagnetic converter to generate the magnetic retaining force; and an electronic processing device configured as a counter that is electrically coupled to the energy converter and operated by the electrical energy generated by the energy converter.
