摘要： A system for monitoring the exposure of a plurality of individuals to a physical or chemical property associated with an environment. The system includes a plurality of portable devices. Each portable device is arranged to be worn or carried by an individual in the environment. The system further includes a control unit for communicating with each of the plurality of portable devices. Each of the portable device includes a detector arranged to measure a physical or chemical property that the individual wearing or carrying the device is exposed to in the environment; one or more physiological sensors each arranged to measure a physiological parameter of the individual; a geolocation module arranged to determine the location of the individual; and a communication module for communicating data collected by the portable device with other(s) of the plurality of the portable devices and with the control unit.

摘要： The invention relates to a method for detecting defects of at least one metal wire of a set of metal wires, in particular in a cable, the method including: a step of emitting a high-frequency ultrasound signal around a so-called specific frequency in the metal wire; a step of reflecting said ultrasound signal in the metal wire; and a step of receiving the reflected ultrasound signal. The emitted ultrasound signal enables the energisation of at least one high-frequency wave capable of propagating in a longitudinal direction of the metal wire and having a phase velocity that is slightly higher than a compression volume wave velocity in the metal from which the metal wire is made.

摘要： Various methods of making a reinforced structure in the ground using a boring tool are provided. One of the methods includes providing a boring tool having a boring tube that can vibrate. The method also includes making a borehole in the ground using the boring tool while causing the boring tube to vibrate. Additionally, the method includes, when the boring tube has reached a predetermined depth, injecting a sealing grout into the boring tube that embeds the boring tube in the sealing grout. Further, the method includes detaching the boring tube from the boring tool, thereby providing a structure reinforced by the boring tube.

摘要： A fire protection device for a structural cable is proposed including taught metal reinforcements (32) and having a first stretch (41), a second stretch (42) and a connection zone (40) of a collar (30) located between the first and second stretches. The fire protection device comprises a protective mat (34) surrounding the structural cable (16) in the first and second stretches (41, 42) and interrupted in the connection zone (40), and a thermally insulating ring (36) more rigid than the protective mat (34), arranged between the reinforcements (32) and the collar (30) in the connection zone (40) and cooperating with the protective mat in order to provide the reinforcements with a continuous thermal protection along the first stretch (41), of the connection zone (40) and of the second stretch (42).
