A method and system are disclosed that allow for the control of transmission characteristics associated with an exchange of protocol data units between a first wireless device and a second wireless device. It is the task of the invention on hand to provide new active agents preventing the formation of amyloid plaques and to dissolve existing plaques, such agents being convenient for therapy, diagnosis and prophylaxis of diseases that are associated with abnormal protein structures. Furthermore, some embodiments provide a civic address as the location information for identifying the location of the caller. The additional amount of said material is selected to produce a desired amount of mass flow. It also transfers energy directly to output voltage. A substantially non-compressible, non-metallic captive ring is interposed between the lip, and the flange and body of the valve coupler.
