Abstract: A signal coupling device comprises a low-frequency circuit including a magnetic ring having an opening and a high-frequency circuit including a rod-shaped magnet. A first-level circuit is formed around the magnetic ring and extends between a first-level circuit input and a first-level circuit output. A second-level circuit is formed around the magnetic ring and extends between a second-level circuit input and a second-level circuit output. The high-frequency circuit includes a third-level circuit formed around the rod-shaped magnet and extends between a third-level circuit input and a third-level circuit output. A fourth-level circuit is formed around the rod-shaped magnet and extends between a fourth-level circuit input and a fourth-level circuit output. The first-level circuit output is coupled to the third-level circuit input and the second-level circuit output is coupled to the fourth-level circuit input.

Abstract: A connection device includes an electrical engagement structure. The connection device includes a connector and a printed circuit board (PCB) based tongue. The PCB based tongue is received and retained in the connector and has a distal end extending toward an open-cavity plug receiving side of the connector in such a way that side edges of the tongue are spaced from corresponding inner walls of the connector. As such, the connector is made compatible to various buses through the PCB based tongue that include contacts that are selectively arranged to correspond to the buses.
