Abstract: An inventory system for objects contained in a space bounded by an enclosure, said system including a tag fixed to each of the objects to be inventoried and a reading point provided with at least one antenna for emitting a wakeup electromagnetic wave confined inside said enclosure so that a tag, on receiving same, becomes active and then emits its identification data intended for said reading point, wherein the system includes means for controlling the emission power of said wakeup electromagnetic wave in accordance with a power-variation model defined by a series of emissions by said or each antenna in stages at power levels different from one stage to another in order to carry out said inventory. The present invention also relates to an inventory method implemented by such an inventory system.

Abstract: A method and system is provided for monitoring a person likely to be in a potentially high-risk area. The method is characterized in that it comprises a step of activating a radio frequency communication apparatus, referred to as a beacon; a step of broadcasting a signal carrying piece of information about a risk occurring in the potentially high-risk area and defines the type of risk and a level of seriousness thereof; a step of receiving a signal carrying the piece of risk information by a badge worn by the person; a step of transmitting by the badge, an identifier of the person to the beacon; a step for determining, by the badge, a piece of information disclosing the person at risk; and a step of transmitting the of disclosing information to a remote apparatus responsible for centralized risk management.
