A polarizing plate has a polarizer and a protective film formed on at least one surface of the polarizer. The optic body has an anterior face, a substantially opposing posterior face, an optic edge, and an optical axis. After determining the high and low operable limits of the deskew values, an optimum deskew setting may be determined and set for the system. The conductive cores are partly exposed beyond the outer insulating jacket and are soldered with the tail portions, respectively. This greatly abstracts a user or application from the IO process. A back rest is secured to the upper surface of the primary leg.
