摘要： The invention relates to a rotary microwave joint device comprising a main circular waveguide constituted by two portions (10, 11) situated as extensions to each other and rotatable relative to one another about their axis of symmetry, each of said two portions (10, 11) being provided with at least one access which is orthogonal thereto, and mechanical means enabling a circularly polarized wave to be obtained in the main waveguide. The invention is applicable to space telecommunications.

摘要： Method of protecting a planetary rover vehicle, that travels in a manner that is at least partially autonomous, against an exterior environment that has become hostile wherein the vehicle takes shelter and emerges from shelter against the exterior environment of its own accord, respectively in response to first and second events delimiting a period in which the exterior environment is hostile. The vehicle is therefore isolated from the exterior environment during this period.
