Patent ID: 7252537

Claim:
A system comprising: an electromagnetic coupler that includes a flex circuit having a first conductor with a first length, an electronic board having a second conductor with a second length, a dielectric positioned to cover at least one of the first length and the second length and to allow alignment of the first length and the second length without contact between the first length and the second length, a visual element disposed along the first length of the first conductor and thereby enabling visual longitudinal alignment of the first length of the first conductor to the second length of the second conductor, and an adhesive material configured to adhere the flex circuit and the board, wherein the first length and the second length are in alignment with the flex circuit adhered to the board, and wherein one of the first length and the second length comprises a pattern having a lateral component that traces a path across the other of the first length and the second length with the flex circuit adhered to the board.
