Patent number: 9970841Abstract: A method for monitoring a civil engineering construction including a first metal reinforcement and a reference conductor element. The first metal reinforcement and the reference conductor being separated by dielectric material and each having a first end that is electrically accessible. The method including injecting an incident electrical signal which is applied differentially between the first ends of the first reinforcement and of the reference conductor element collecting reflected signals returning along the conductors in return, and analyzing the reflected signals by comparing them against reference signals in order to determine any potential structural defect in the first reinforcement.Type: GrantFiled: December 18, 2013Date of Patent: May 15, 2018Assignees: SOLETANCHE FREYSSINET, INSTITUT FRANCAIS DES SCIENCES ET TECHNOLOGIES DES TRANSPORTS DE L'AMENAGEMENT ET DES RESEAUXInventors: Frédéric Taillade, Gilles Hovhanessian, Nicolas Freitag

Patent number: 8307725Abstract: The invention proposes a system for obtaining information relating to a pipe (4) conveying a flow of fluid (28), and/or relating to the fluid. This system comprises a module (1;30) comprising means (10) of acquiring data, subsequent analysis of which makes it possible to obtain information relating to the pipe and/or the fluid, and means (11) of storing the data which said data acquisition means acquire, the self-contained module being arranged to be pushed by the fluid flow after being introduced into the pipe. It also comprises a mechanical link (2) which is connected to the self-contained module and accessible from outside the pipe.Type: GrantFiled: April 17, 2009Date of Patent: November 13, 2012Assignee: Soletanche FreyssinetInventors: Jerome Stubler, Bernard Basile, Gilles Hovhanessian

Publication number: 20110257926Abstract: Method for the analysis of the thermal behaviour of a structure including an energy-consuming appliance for providing a thermal environment by heating or cooling, the structure being modelled using a thermal model so that a relationship between a theoretical consumption by said appliance and a reference temperature inside the structure satisfies a determined criterion. According to this method, an actual consumption by said appliance, a temperature actually obtained inside the structure and at least one parameter relating to a use of the structure are measured; a variation between the aforesaid relationship and a corresponding relationship between the actual consumption by said appliance and the temperature actually obtained inside the structure are estimated; and when the estimated variation exceeds a threshold, a contribution relating to the use of the structure to said variation is estimated by taking account of said measured parameter.Type: ApplicationFiled: April 15, 2011Publication date: October 20, 2011Applicant: Soletanche FreyssinetInventors: Jerome Stubler, Bernard Basile, Gilles Hovhanessian
