A mobile station in a communication system including a base station, the mobile station includes a unit for sending a signal that allocates a plurality of different Zadoff-Chu sequences to a frame to the base station. Those eddy currents are generally parallel to the surface of the molten metal and so have greater magnitude and extent that eddy currents perpendicular to the surface. According to one aspect of the present invention, in addition to the normal voltage levels applied to the cell as part of the reading process, a time varying voltage is applied to the cell. Each of the opposing sidewalls includes a plurality of shelf mounting points. In one embodiment, the invention may provide a mechanism to hedge the compensation expense liabilities of an employer providing deferred compensation to one or more employees.
