The invention relates to a device for monitoring the integrity and soundness of a mechanical structure, such as an aircraft. The device comprises a control unit, a radio frequency transmission means, and an electric battery. The control unit recovers data from a set of digital and/or analog sensors. The radio frequency transmission means enables the control unit to transmit the data received from the sensors to a man/machine interface. The electric battery powers the device and is rechargeable. The device further comprises a module for recovering electromagnetic energy capable of converting the recovered electromagnetic energy into electric power so as to recharge the battery and/or directly power the device.

A method for estimating the lifetime of a deep-submicron-generation integrated electronic component, linked to a wear mechanism occurring in previously defined special conditions of use, said component being of a deep submicron type, with very large-scale integration, commercially available off the shelf, wherein one assumes that the same sample population always experiences a failure due to: the most predominant failure mechanism, during the period of useful life, described by an exponential law, and the most critical wear mechanism, represented by a Weibull distribution at the end of the previous period.

To solve a leakage problem in a box, it is proposed to provide the box with an electronic circuit for measurement of its specific humidity. It is shown that by comparing this current specific humidity to an initial specific humidity and by evaluating the difference found in relation thereto, one has a reliable tool for measuring the permanence of tightness.

Electronic device for measuring leaktightness

A monitoring device of environmental parameter values of an environment surrounding a system. The device includes a sensor to these parameters, and includes a capability to transmit, in real time, each measurement to a processing unit. The processing unit is installed in the system and includes a capability to filter the transmitted measurements. This processing unit comprises a capability to determine cycles from the measurements thus simplified as well as a capability to calculate, in real time, of a percentage of length of consumed life of the system, from the thus determined cycles.
