Abstract: A method for the management and maintenance of an aircraft including a zone with a high degree of security, a man-machine interface of the aircraft being included in the zone with a high degree of security and necessary for a maintenance operation to be performed by a maintenance operator on a device of the aircraft to be maintained placed outside the zone with a high degree of security. The method includes: connection of a first device to the high-security zone; connection of a second device to a third device; reception of the first device by the second device of the man-machine interface of the aircraft and transfer of information for display of the man-machine interface of the aircraft to the third device; and connection of the second device to a server by means of the telecommunication network in order to obtain information from the server intended for the third device.

Abstract: A defective-pixel detection method included in an image-processing procedure, including a pixel-processing procedure applied to pixels of an image supplied by an image sensor. Each pixel is associated with a classification value representing a state of said pixel. The method includes, for each pixel: applying the pixel-processing procedure; analyzing a result of the pixel-processing procedure; in the event of obtaining an unusual result representing a defect on a photosite of the image sensor that supplied said pixel, incrementing a number of detections of an unusual result for said pixel; and associating said pixel with a classification value representing a defective pixel when said number reaches a first threshold.

Abstract: A method for processing high-frequency movements in an optronic system including an image sensor functioning with a first acquisition frequency, each image obtained by the image sensor representing a scene, the method includes a step of obtaining signal values representing a movement of the scene from a high-frequency movement sensor functioning with a second acquisition frequency higher than the first acquisition frequency, a step of determining values representing a movement of an image in the course of acquisition by the image sensor from values of the signals representing the movement of the scene, and a step of transmitting the values representing the movement of the image in the course of acquisition by the image sensor to a movement compensation device so that the movement compensation device can compensate for the movement of the image in the course of acquisition by the image sensor.

Abstract: A method for maximising a quantity of enabled transmission requests from a set of transmission requests in a mobile wireless network comprising a plurality of mobile nodes. Said method is implemented by a master node and activated on reception by the master node of an event belonging to a predefined set of events comprising a first type of event involving a modification to the topology of the network. The method comprises: obtaining a set of transmission demands; if the event is of the first type, implementing an optimisation procedure comprising: defining transmission rate and latency constraints; defining at least one subset of the set of transmission requests; associating each subset defined with a cost function; determining a subset of maximum-cardinality compatible with said constraints and minimising the cost function, said subset representing the transmission requests to be enabled.
