Abstract: A method for self-discovery of an array of linear sensors, wherein each linear sensor has a unique identifier, the method includes: for each accessory, identifying a linear sensor situated upstream or downstream of the linear sensor; sending a local request to the identified sensor/accessory; sending a general request to the plurality of linear sensors and/or accessories in the array; receiving a response to the at least one local request by said linear sensor and/or the accessory; sending a response to the general request by said linear sensor and/or by the accessory, the response to the general request sent by the linear sensor comprising the unique identifier; and processing the response to the general request received from each linear sensor and/or from each accessory by the central processing unit allowing to reconstitute the logical topology of the network as a function of the unique identifiers received.

Abstract: A communication module is provided for a sensor, for use in a detection device, including a plurality of sensors, having at least one upstream receiver for receiving an interrogation signal from upstream of the sensor and transporting it to the sensor, and receiving from the sensor a response signal and transporting it upstream of the sensor; —at least one downstream transporter for transporting an interrogation signal downstream of the sensor; —at least one sensor short-circuit, displaceable between an open position wherein the upstream receiver is linked to the sensor, and a closed position in which the upstream receiver is disconnected from the sensor and connected to the downstream transporter; and —at least one controller, for controlling the sensor short-circuit and arranged to maintain the sensor short-circuit: —in the open position until the emission of the response signal, and —in the closed position after the emission.

Abstract: A detecting element is provided for detecting leaks of an electrically nonconductive liquid, in particular of hydrocarbons, as well as a detection cable and a detection system using such a detecting element. The detecting element includes a detection member made of a material which inflates upon contact with the liquid and which is loaded with electrically conductive particles, to be conductive when not contaminated by the liquid, and to lose the conductivity when inflating from contact with the liquid. The detection member is electrically connected to an electronic management module, which is arranged for detecting the presence of the liquid by noticing a decrease in the conductivity of the detection member. In a preferred embodiment, the detection cable includes four insulated conductive wires, one of which is embedded in the detection member which is itself protected by an inflatable casing, which is also insulating and water-proof.
