Abstract: A sealing system can be mounted between a body of a vehicle and a box fastened to the body. The body and the box include a first opening and a second opening, respectively, opposite each other. The sealing system surrounds the passage and includes a bellows having a first end in contact with the body so as to surround the first opening, and a second end in contact with the box so as to surround the second opening. The sealing system comprises a compression spring. Each end of the spring acts on one of the two ends of the bellows so that the spring moves the two ends of the bellows away from each other.

Abstract: A system, apparatus and a method to connect at least two items of equipment, a first item of equipment having a first confidentiality level and a second item of equipment having a second confidentiality level, the two items of equipment in communication with equipment external to the system through the use of a protocol wherein the system includes at least: a medium allowing the transmission of data between the first and second items of equipment; an interface between the medium and the first item of equipment; an interface between the medium and the second item of equipment; first module to allow a first monodirectional adaptation of the protocol and to allow the transmission of data monodirectionally; and a second module to allow a second monodirectional adaptation of the protocol and to allow a reception of the data monodirectionally from the first module.
