Abstract: A method for monitoring the integrity of a set of air bleed lines from propulsion engines of an aircraft by: at the start of a use of the aircraft, sending air from an auxiliary power unit into the various lines; over a predetermined period of time, acquiring temperature measurements from temperature sensors associated with the lines; for each line, determining a gradient for rate of change in temperature with respect to time during this period of time; determining a discrepancy between the gradient for rate of change in temperature with respect to time corresponding to a line and a gradient for rate of change in temperature with respect to time corresponding to at least one other line; determining a condition indicator for the condition of the line as a function of the discrepancy determined for said line.

Abstract: A method and a device are disclosed for concentration of messages transmitted by at least two separate transmitters in a communication network to which there are connected these transmitters and an addressee of the data contained in the messages. After receiving the messages to be concentrated, the data contained in these messages are extracted. A concentration frame comprising the extracted data and at least one information item making it possible to identify the addressee is then constructed and transmitted The size of the concentration message is smaller than the maximum size of the data packets exchanged in the communication network.

Abstract: Methods and devices for non-intrusive identification and communication between a server node and at least one client node in a communication network. An identification message is first transmitted to at least one client node, the identification message including at the application level a duplicate of the addressing data, the physical address and the internet address of the server node, also contained in the MAC and IP layers. The reception of at least one couple of addresses from at least one client node, wherein a couple of addresses from a client node includes a physical address and an internet address according to the same duplication strategy, can be used for identifying the client node by the server. Similarly, the methods and devices can be used for identifying in a client node at least one server node in the network.

Abstract: The invention in particular has as an object supervising a scheduler for the management of processing time sharing in a multitask data-processing system comprising a computation unit having a standard execution mode and a preferred execution mode for executing a plurality of applications. The execution time for the said plurality of applications is divided into a plurality of periods and a minimal time for access per period to the said computation unit is determined for at least one application of the said plurality of applications. For at least one period, the said preferred execution mode is associated with the said at least one application and the said at least one application is executed according to at least the said minimal time for access to the said computation unit. For the said at least one period, the said standard execution mode is associated with the applications of the said plurality of applications and at least any one of the applications of the said plurality of applications is executed.

Abstract: A method and a device for exchanging data between a computer and at least one expansion card of an equipment item having a network interface and at least one expansion card is disclosed. The computer and the network interface are connected by a communication network. The network interface and the at least one expansion card are connected to the same industrial bus. After assignment of a virtual network address in the communication network to the at least one expansion card, the network interface is configured with the virtual network address in order to make it possible to identify the network interface in the communication network as representing the at least one expansion card.
