A system and method are described that allow for both call control data and voice data to be transferred between a mobile radiotelephone and a set-top box or residential gateway. The first and second oscillators are connected to first and second eccentric pins which are installed in upright at positions where phases are substantially opposite above and below the eccentric joint portions. A second step involves spraying a surfactant on the bead of silicone caulking compound. The frame structure hereof improves accuracy and rigidity of the suspension-supporting portion of the vehicle body frame, and provides a simplified structure as compared to conventional frame structures. The surface properties may be determined using FTIR.
