Provided is an apparatus and method for transmitting a signal based on interleaving delay diversity. The method and system of the present invention includes creating setup information in the client and providing the same to the server, wherein the setup information enables the server system to identify the client, to identify where to find information the server system needs for synchronization, and to provide appropriate commands for the client. The lithium-metal-fluorophosphates comprise lithium and at least one other metal besides lithium. The blended stream is then passed through a bed of solids having a suitable surface area so that a substantial amount of the sulfur moieties are removed by the aqueous phase. The first and second chips may be placed in close proximity and electrically connected together. The light guide is designed in such a manner that light exiting the light guide again at least partially illuminates the surface of the control unit.
