A manipulative tool for demonstrating the relative positions and configurations of articulators and other oral structures, when making phonetic sounds. The method includes receiving a request to transmit data to a destination mobile device, and identifying a destination IP address of a destination mobile device within the request. The marine air conditioner may comprise an evaporator coil and a drain pan. The shunt resistor may be made of a material having a near zero thermal coefficient of resistivity to test a quality of the TuMR read sensor. Preferably, each of the legs of the control arm has a different spring rate to provide a change in wheel camber under the deflection of the control arm during wheel travel.
