A meshed HVDC power transmission network comprises at least three HVDC converter stations interconnected in a first closed path by at least three transmission lines. After the license has been installed to the vehicle’s OBEMC by the Invention, the vehicle will not exceed the speed set by the user of the Invention, regardless of who operates the vehicle or what input they give to the vehicle’s throttle mechanism. The direct imaging can be assisted with at least one of MRA imaging, CT angiography imaging, or 3DRA imaging as the roadmap acquired prior to or during 3D stereoangiovision. The printer feed roller moves the printed media sheet along the entry guide to the drive roller of the duplexing module. A comparison output is used as a control signal and the subordinate LPF 21 and main LPF 11 are controlled to have a desired cut-off frequency. The device is configured to place the oscillator in the synchronous oscillation mode before each application of a burst of the second periodic signal to the antenna circuit, then place the oscillator in the free oscillation mode.
