Abstract: A system and device is provided for formulating alerts of the items of equipment of an aircraft. The device includes a database of virtual objects representing the items of equipment for constructing a virtual model representative on the one hand of the topological configuration of the network of items of equipment and on the other hand of the configuration of the chain of functional applications implemented by the items of equipment, means for each virtual object to formulate a request for consulting the status of the functional application carried out by the item of equipment associated with the object and means for detecting alerts for formulating requests for consulting the status of each of the objects of the virtual model so as to detect anomalies of configuration of the topology of the network of items of equipment and of the chain of functional applications of the virtual model and to transmit the alerts associated with the anomalies. The device detects and manages the alerts of an aircraft.

Abstract: The invention relates to a device for system diagnosis of an aircraft. The device includes: means for the monitoring of equipment of the system, the means for emitting messages of observations on the basis of effects produced by equipment; means for the determination of a set of observations on the basis of the messages of observations arising from the monitoring of a log of the messages of observations and of a model representing a current state of the system; means for the determination of indictments on the basis of observations of the set of observations and of a behavioral model of the system, the indictments being logical relations between operating modes of equipment having produced effects; and means for the determination of maintenance operations on the basis of the indictments.

Abstract: The present invention concerns the field of communication networks having a structure similar to an aeronautical telecommunications network (ATN). In particular, the invention relates in particular to how to simply simulate a large number of subscribers exchanging information via an ATN with equipment under test so as to test the ability of the equipment to exchange, via an ATN, information with a large number of subscribers. The inventive architecture comprises in particular a modified ATN stack enabling several separate communication channels to be opened on the ATN for a common application, said application being simultaneously implemented by several simulated entities. The modification of the ATN stack concerns in particular the assignment, by the corresponding ASE layers, of AEq identifiers to the applications implemented by the simulated entities. This modification also concerns the association of a network identifier TSEL with an AEq identifier from a modified ASE layer.

Abstract: The invention concerns a method for making a card with tips for testing semiconductor chips with microsphere bond pads. A first adhesive coat is vacuum deposited on a flexible polyimide film, followed by a second metal coat. A combination of UV photolithography and electroforming of a metal material enables to obtain the implantation of the tips. The pattern of the strip conductors is obtained by a second UV lithography operation whereby the second metal layer and the first adhesive coat are etched. An insulating protective resist is deposited on the active conductive zone. The flexible film is mounted on a truncated maintaining component whereof the vertical translational and planar rotational movements are made possible by a guide supported on a spring suspension. The defective alignment between the plane of the tips and the plane of the tips and the printed circuit plane is corrected by a correcting system with three support points adjustable with screws.
