Embodiments of the invention provide a transparent electrode, an array substrate and a liquid crystal display device. The system and computer-implemented methods and processes are particularly useful in connection with trains having at least one locomotive, where the train includes multiple target devices, such as a train event recording system and the like. A cap is shaped to close the opening and is electrically isolated from the container, while having a second terminal in electrical connection with the second electrode. The operational amplifier is in the feedback network and has at least two operational amplifier input terminals and an operational amplifier output terminal. An insulating film formed on the surface of the inspection electrode is broken by utilizing a fritting phenomenon so as to bring the inspection electrode into electrical contact with the inspection electrode. The method includes displaying a message regarding whether to set a dual SIM active function, selecting an area included in the message, and confirming a setting of the dual SIM active function upon the selection of the area included in the message.
