A fiber reinforced polymer part is fabricated by rastering a deposition head over a substrate, and additively forming part features by extruding a polymer having an entrained continuous reinforcement from the deposition head onto a substrate. Various embodiments for providing authentication and mobility signaling when a mobile node moves from a 3GPP access network to a non 3GPP access network and vice versa are described. When the VCE of the CR BJT exceeds a threshold voltage above the normal conduction VCE range, the control circuit increases the base drive current to accelerate the CR BJT turn-on process. To combine, an index about the adequacy of each model, in other words, an index indicating a reliable level of likelihood calculated from the each potential classification model, is also calculated. The modulator includes two sets of electrodes placed respectively on each of the interferometer arms, one in the non-reversed region of the electro-optical material, the other in the reversed region, and a delay line placed between the control electronics of the electrode sets introducing a delay equal to the light propagation time in the first electrode set.
