A method is provided that includes measuring amplitudes and phases of signals reflected off a reflector of a satellite, with the amplitudes and phases forming a first set of measurements. This so called Polyol\u201d method consists of heating of suited precursor materials in a multivalent, high-boiling point multivalent alcohol like glycols with the general formula HO\u2014, \u2014H where n=1-10 or HO\u2014n\u2014H where n=1-10, or other polyols with the general formula HOCH2\u2014n\u2014H where n=1-10, like for example the tridecane-1,4,7,10,13-pentaol. A rollover warning is generated for any current position of the vehicle at which the forecasted future speed for at least one particular point on the road forward of the vehicle exceeds the determined maximum safe speed at particular point. The device determines from two or more of the received SR packets a first relative rate of a remote media card clock to the remote system clock rate. The package management instructions are sent to the client device. The regulator may also include a set of cascaded flip-flops corresponding to phases of the converter.
