A sulfonic acid-functionalized vinyl alcohol copolymer is provided which is characterized by a substantial absence of compositional drift. The condition monitoring system further includes a processor coupled to the memory device and the at least one input channel. Each station has an upstanding pin offset from the center point of the station in a different direction. The capacitor fixing sections are located inward of the frame more than the unit fixing sections. Application data files can be deployed from an author system to remote servers.
