An apparatus is disclosed for permitting a mobile terminal having multiple, heterogeneous network connections to set up and maintain virtual connections over multiple networks to either the same or to multiple destinations. A spring may be coupled to the body for securing the terminal end of the trough member to the coupler, the spring including first and second spring arms extending generally in opposition to one another in a plane generally parallel to the longitudinal direction. The programmed addresses are applied to a defective column decoder that determines which column select signal should be shifted downwardly and which column select signal should be shifted upwardly. The one or more support brackets are at least partially located in a rear cavity of the golf club head.
