Abstract: A method for alerting a driver of an automobile vehicle. The method includes: obtaining an area not being monitored by the driver and activating sensors of the vehicle relating to the unmonitored area; analyzing data captured by the sensors relating to the unmonitored area in order to detect an event to come; and rendering or not to the driver information representative of an alert depending on the result of the analysis.

Abstract: A method for managing an emergency state of a first vehicle, implemented by a remote server. The method includes: receiving an indication of the emergency state of the first vehicle; estimating a first geographical area in which the first vehicle is able to be positioned for a given time period; and sending an alert message to at least one detecting element, positioned at a traffic lane, said at least one detecting element being able to be positioned in the first geographical area for the given time period.

Abstract: A method for managing an urgency state of a first vehicle, implemented by a managing system. The method includes: receiving a first indication of the urgency state of the first vehicle; determining a list of potential itineraries including at least one potential itinerary of the first vehicle; and sending an alert message to at least one detecting element, located at a traffic lane, the at least one detecting element being determined as a function of the at least one potential itinerary of the first vehicle.

Abstract: A method for producing biomethane by purifying biogas from non-hazardous waste storage facilities involves compressing the initial gas flow, introducing the gas flow to be purified into at least one adsorber loaded with adsorbents capable of reversibly adsorbing the VOCs, and subjecting the VOC-depleted gas flow to at least one membrane separation step in order to partially separate the CO2 and O2 from the gas flow. The method also involves introducing the retentate from the membrane separation step into at least one adsorber loaded with adsorbents capable of reversibly adsorbing the major portion of the remaining CO2, subjecting the CO2-depleted gas flow exiting the adsorber loaded with adsorbents capable of reversibly adsorbing the major portion of the remaining CO2 to a cryogenic separation step in a distillation column in order to separate the O2 and N2 from the gas flow, and recovering the CH4-rich flow from the cryogenic separation step.
