Patent ID: 7262949

Claim:
An electrode arrangement comprising: a pair of shielded electrodes that is complementary and superposed to each other including, a first shielded electrode and a second shielded electrode; a plurality of shielding electrodes that are superposed to each other including at least a first shielding electrode, a second shielding electrode, and a third shielding electrode; a common conductive coupling portion; wherein the plurality of shielding electrodes are coupled to one another by at least the common conductive coupling portion; wherein the first shielding electrode is in a first position; wherein the first shielded electrode is in a second position adjacent the first shielding electrode; wherein the second shielding electrode is in a third position adjacent the first shielded electrode; wherein the second shielded electrode is in a fourth position adjacent the second shielding electrode; wherein the third shielding electrode is in a fifth position adjacent the second shielded electrode; wherein the first shielded electrode and the second shielded electrode are sandwiched by predetermined shielding electrodes of the plurality of shielding electrodes; and wherein the pair of shielded electrodes are conductively isolated from both the plurality of shielding electrodes, and from each other.
