A method of recovering the state of a system, which system comprises at least one counter, which counter represents an instantaneous state of an entity in a system. A transparent conductive film can be formed using the metal nanowires. The lower back panel has a forward flange and a backward flange extending a certain distance from its front and rear ends. This makes the recording ratio of the yellow ink Y lower than the recording ratios of cyan ink C and magenta ink M. The auxiliary capacitor is formed in a region of the interlayer insulating film in which the upper insulating layer has been removed by etching. The apparatus may be used for a variety of applications such as, for example, personal health monitoring, clinical diagnostics, safety and law enforcement monitoring, and others.
