An interconnect assembly includes a number of interconnects combined in a preferably planar dielectric carrier frame having resilient portions acting as spring members in conjunction with their respective interconnect’s rotational displacement during operational contacting. The first element includes a first peripheral portion and a plurality of first contact points exposed by the first peripheral portion. In particular, a call is connected between a mobile station and a remote station through a media gateway. A masking layer is formed which defines at least one trench. The channel acknowledge decision message includes broadcast timing information of the neighbor node. The present invention provides a composite semipermeable membrane that achieves a balance between high solute removal properties and a high permeate flow rate and has high organic-solvent resistance, and a method for producing same.
