In a mobile terminal device that executes a function setting by using a memory card, when insertionremoval of the same memory card are repeated, an original function setting can be restored automatically to omit a resetting and also the user’s operational burden can be lessened. Multi-layer structures including ferromagnetic layers deposited on the IrMnN films are also disclosed. Based on the at least one normalized signal obtained in this way, a threshold condition is set and a rate at which at least one second measurement signal fulfills the threshold condition is monitored, wherein each of the at least one second measurement signal is derivable from a corresponding normalized signal and indicative of pain-related activity in the patient.
