A transmission line impedance transformer may include a printed circuit board having a dielectric layer and an electrically conductive layer thereon defining a medial interconnection portion, and first and second lateral loop portions extending laterally outwardly from opposing first and second sides of the medial interconnection portion. The in-vehicle system communicates with the server system using a wireless communication link 110, such as over a cellular telephone system. The leakage diode is matched to the trigger diode to shunt any leakage current from the trigger diode to ground. The capacitance of the multilayer ceramic capacitor depends on the unoxidized internal electrode layers other tan the oxidized ones. The manipulator can be used for other application in an embodiment without the mouthpiece andor in combination with a bite registration shape that is part of the manipulator frame.
