A method is provided for detecting a hybrid automatic repeat request message. By interposing the insulating film between the recording layer and the plug, an effect of reducing programming current of a phase change memory and an effect of preventing peeling of the recording layer can be achieved. Also disclosed are heat transfer systems, assemblies, fuel cell systems and methods of maintaining a conductivity of less than 200 \u03bcScm in a heat transfer fluid that employ the disclosed colorant treated ion exchange resins. Data symbols of the detected codes are obtained from the data symbols of the identified parent codes. A control unit within the mechatronic system performs error detection and an arithmetic unit outside of the mechatronic system performs error identification.
