Abstract: For associating different technologies of a microstrip line and of a rectangular waveguide, for example on a ceramic, in a transition device including a mode transformer between the line integrated into a printed circuit board, and the waveguide, the board includes a housing containing the waveguide with a large sidewall coplanar and coaxial to the strip of the line and another large sidewall fixed onto a metallic layer of the board at the bottom of the housing. A linking metallic element bridges a mechanical tolerance gap between the transformer and one of the line and the waveguide. The transformer can be integrated into the board, or into the waveguide in a microwave component.

Abstract: Target land area is three-dimensionally located using an optical sensor and a radar sensor in satellites. The positions of the satellites are measured and images are captured when the sensors point toward land areas. The aiming direction of the optical sensor for each area is measured. The distance between each area and the radar sensor pointing thereto is measured. Images of land areas captured by the sensors and covering common areas are matched. The distance between the target area selected from the common areas and the optical sensor is accurately determined on the basis of the positions of the sensors, the distance between the target area and the radar sensor, and the aiming direction of the optical sensor, which are associated with the images covering the target area.

Abstract: System (1) for securing a data processing application, the said system comprising: first means (2) for interfacing with a security device (3); second means (4) for interfacing with the user; third means (6) for interfacing with the application and adapted for intercepting any request to use the said security device originating from the said application destined for the said security device; authentication means (8) connected to the first and second interfacing means, adapted for authenticating the user as legitimate user of the security device by requesting at least one secret; means (10) for storing the result of the authentication; validation means connected to the storage means and to the first and third interfacing means, adapted for authorizing any request originating from the application, destined for the said security device if and only if, the user is authenticated.

Abstract: A workstation with position memory includes a stationary flat mounting, a plate translatably mounted relative to the stationary flat mounting and a locking system secured to the plate. The workstation also includes a fastener secured to the stationary flat mounting, a strap including a first end, an intermediate portion and a second end, the first end being attached to the fastener and the second end being free from any strain. The locking system has a first open position in which the locking system can slide along the intermediate portion and a second closed position in which the locking system is retained in a locked position along the intermediate portion. The invention has a direct application in the field of military vehicles.

Abstract: A method for identifying a host-type radiocommunications network of a user terminal from at least two networks forming a radiocommunications infrastructure including a base station shared by the networks, and a network core for each of the networks. A beneficial application of the method lies within the field of professional mobile radiocommunications networks.

Abstract: A method for attachment and authentication of a user terminal of a home type radiocommunication network with a visited type radiocommunication network, the home network including home means for attachment to a packet network and the visited network including: at least one visited base station able to ensure radio transmission and reception with user terminals located in at least one visited cell attached to the visited base station; visited authentication and control means of user terminals able to authenticate the user terminals attached to the network; and at least one visited distribution gateway ensuring radio reception and transmission with the at least one visited base station.
