A touch position coordinate detecting system is provided that is based on surface acoustic waves and includes arrays of reflective patterns between a touch region of a touch panel. The substrate has a front side, a back side, and an outer edge. The interference values indicate effects of the states of the one or more memory cells on the state to which the memory cell is to be programmed. A protective scheme is used to keep such data from being updated while the restore is taking place. According to the invention, the comb includes self-stripping contacts associated with notches for simultaneously introducing each insulated conductor of the cable into a notch and for engaging it into the stripping contact associated with said notch.
