Abstract: A device for testing a circuit made up of a printed circuit board on which components, preferably dummy components, are assembled by the solder connections. An enclosure of the testing device subjects the circuit under test to a schedule of thermo-mechanical and/or vibration constraints. Bridges of electrical resistors, forms a hardware portion of the testing device. A software portion of the testing device sets a detection criterion representing damage to one or more solder connections and displays the results of the test. An input/output interface converts each electrical resistor measurement of the tested chains of solder connections into data for use the software portion. An adjusting component modifies the criterion for detecting damage to the solder connections.

Abstract: To produce a memory which resists ion or photon attack, a memory structure is chosen whose memory point behaves asymmetrically with regard to these attacks. It is shown that in this case, it is sufficient to have a reference cell for an identical and periodic storage structure in order to be able to correct all the memory cells assailed by an attack. An error correction efficiency of ½ is thus obtained, with a simple redundancy, whereas the conventional methods make provision, for the same result, to triple the storage, to obtain a less beneficial efficiency of ?.

This device includes: a first member extending axially along a longitudinal axis; a second member extending axially along the same longitudinal axis, the two members being guided translatably relative to one another; a friction element extending between the two members and connecting them completely to each other by friction in an axial translational direction for any force below a threshold ‘s’, the force tending to create a relative translational movement of the two members along the longitudinal axis; an adjustment device enabling the value of the threshold to be adjusted. Thus adjusting the slip threshold of the friction element enables the dissipation conditions to be adjusted.

Abstract: A method for generating and optimizing physical system architecture by modeling a problem in the form of a model. The physical architectures (AP1, AP2, . . . , APN) are generated using the model and algorithm that searches for a function with viable and valid combination of components. The physical architectures are evaluated according to a plurality of attributes or criteria using analysis modules based on the model. A part of the physical architectures is selected based on dominance relations. New physical architectures (AP?1, AP?2, . . . , . . . , AP?N) are generated by applying genetic operators to the physical architectures (AP1, AP2, . . . , APN). The results are synthesized by retaining a part of the physical architectures.

Abstract: A connecting rod is composed of two or more assembled shells made of a composite, open over the entire length of the connecting rod. The shells incorporate clevis joints for introducing stress at each of their ends. The shells are produced separately then assembled together to form a sealed section. Each shell is made from a material preimpregnated with long fibres. The production of each shell is simplified due to the overall shape of the shell as a simple curve, thus a shell may be produced industrially, for example, by thermoforming a flat composite preform. The two shells are assembled by simultaneous polymerization of the shells, by bonding, by welding, by riveting or any other assembly process or combination of assembly processes that are compatible with one another. The structural composite connecting rod obtained has very good mechanical properties, especially in compression, with a simple and economic production process.

The invention is such that the monitoring device can be incorporated into the electronic assembly, preferably, the monitoring device is autonomous both as regard to processing the measurements and calculating the damage.
