Abstract: The invention concerns a system for monitoring physical and/or analogue parameters relative to the parts of an engine, said system comprising at least one electronic control unit (30a) configured to call up data, via at least one antenna (20a), from a surface acoustic wave sensor located on one of said parts, characterised by the fact that:—the engine (M) is compartmentalized, each compartment (Ma, . . . , Mf) comprising a plurality of mobile or fixed parts of which the physical and/or analogue parameters need to be monitored, —each of these parts to be monitored is provided with a surface acoustic wave sensor (101a, 102a, 103a, . . . , 101f, 102f, 103f), each of said sensors having a distinct resonance frequency specific to it,—an antenna (20a, . . . , 20f) is installed inside each of the compartments (Ma, . . . , Mf), each of said antenna being connected, alone or in pairs, to an electronic control unit (30a, . . . , 30f, 30ab, . . . , 30ef),—each antenna (20a, . . .

Abstract: A mooring chain stopping device including a locking housing with a channel inside which a mooring chain slides, and including a connection to a buoyant structure to direct the channel axis to the pulling axis of the chain, the housing having bolts inhibiting sliding of the chain in the channel and a device for measuring tension in the chain built into the locking housing. The measuring device includes a chamber including a defonnable shell, and filled with a liquid; a bearing part movably mounted in the locking housing, the bearing placed between the bolts and the chamber, and engaging the shell wall to pressurize the liquid, the bearing arranged so the forces exerted by said mooring chain on the bolts cause the movement of the bearing part and the pressurization of said chamber; and at least one pressure sensor to measure the pressure of the liquid.

Abstract: Combined distribution duct for low current measuring cables and for high voltage ignition cables in internal combustion engines. This device combines a wiring duct having one connector per sensor for each cylinder, and one or more outlets supplying the corresponding ignition coil and any other control. The duct is composed of a steel tube clamped to the engine or divided into two mutually engageably portions having internal grooves for receiving a screening plate, electronic adapter boards, or cable attaching accessories. The two portions may be separated by an internal grooved profiled section. The device is suitable for all kinds of internal combustion engines, but particularly high-powered engines, especially stationary and marine engines.
