A precessional gyroscopic exercise device includes a housing containing a tiltable rotor assembly. Steps b) and c) are carried out discontinuously and at least partially together. Responsive to selection of a demonstration set by the user, the scheduling server selects one of the provisioning servers to host the scheduled demonstration and notifies the selected provisioning server of details regarding the scheduled demonstration. Intensity of the electromagnetic wave having a predetermined wavelength and being introduced from the end face is enhanced in the electromagnetic wave resonator due to resonance of a surface wave having an electric field component in a direction of film thickness of the positive dielectric thin film and without having a cut-off frequency. The controller is adapted to determine whether the driver of the vehicle is the primary driver or the secondary driver based on the driver status signals.
