Abstract: A method of managing a system provides a minimum service in the system. The system includes a set of pieces of equipment including data-gathering equipment and/or equipment that is to be controlled, the pieces of equipment being connected to a management module via respective first communications links. The management module is suitable for determining a control command as a function of data received from at least one piece of data-gathering equipment via a first communications link and for transmitting the control command to at least one piece of equipment that is to be controlled. The method is adapted to detect an absence of application signaling activity from the management module over a predetermined time period and to trigger a minimum service by sending an alert message to at least one piece of equipment of the system.

Abstract: Laser emission device with integrated light modulator comprising: a multilayer waveguide comprising, on a support layer, a first guiding layer, a first doped layer, a second guiding layer of light amplifying material, and a biasing second doped layer opposite the first doped layer, the waveguide comprising a laser amplification section (50), a light modulation section (52) comprising an extraction zone for radiating the light, a transition section (51) inserted between the laser amplification section and the light modulation section, a positive first electrode for injecting a pumping current into the laser amplification section, a positive second electrode for injecting a modulation signal into the modulation section, a negative third electrode, and a reference fourth electrode, the second doped layer comprising an electrical insulation situated in the transition section to form a resistive channel.
