Method for detecting a change in the environment near at least one portion of a hoisting, traction or boundary cable which conducts electricity. The change in the environment is linked to the relative movement of at least one person, animal or object with respect to the portion. The method includes the step of detecting a variation in the capacitance of the portion. The variation is representative of the movement.

Abstract
The invention relates to a composite coating comprising a solid matrix of the ceramic type produced via a sol/gel method, in which a lubricating filler is included in the form of crystalline lamellar particles comprising a stack of 2 to 5 carbon sheets. The coating of the invention can be used to improve the tribological behaviour of substrates such as metal substrates in relation to all types of substrates (metal, polymer, ceramic). The invention also relates to a method for producing corresponding coated substrates, to the charged sol which is a precursor of said coating, and to the production method thereof.
