    摘要: A foldable ramp for evacuation of a vehicle, the ramp including hingedly connected primary and secondary side members, a primary fixed panel fixedly attached the primary side members, a primary flipping panel extending between the primary side members adjacent the primary fixed panel and having a first end pivotally connected to the primary side members and a second end free from the side members, and a secondary flipping panel extending between the secondary side members and having a first end free from the side members and hingedly connected to the second end of the primary flipping panel and a second end pivotally connected to the secondary side members. The ramp is configurable between a folded and a deployed position, with the panels in the deployed position forming a ramp surface and the panels in the folded position being stacked one against the other.

    摘要: The invention relates to an optical fiber transmission system using soliton signals and wavelength division multiplexing. To reduce the effects of collision-induced jitter on the soliton channels, the invention proposes to interchange the wavelengths of the channels of the multiplex at least once, so as to invert the sign of the residual frequency variation induced by the asymmetrical collisions on the signals of the channels. The invention is applicable in particular to transmission systems implementing a frequency allocation scheme that guarantees that the bit times of the various channels are synchronous at regular intervals.
