Abstract: A method and a device for guiding an individual in an environment comprising at least one actuator capable of being remotely controlled is disclosed. The method is implemented by a computer, and comprises determining, based on a starting point and a destination point for the individual in the environment and based on a digital model of the environment comprising a location of each actuator, a path within the environment connecting the starting point and the destination point, determining, from the determined path, a set of actuators located on the path, and issuing of an activation command for at least one actuator in the set of actuators in order to guide the individual along the path.

Abstract: The invention relates to a method for rebuilding an ad hoc network, in particular a ZigBee-type network consisting (A) in collecting data of the network nodes in terms of quality of connections and non-optimal network trees, (B) in calculating a current optimised structure, (D) in setting optimisation data and injecting them into the network and (E) in rebuilding the network according to said current optimised structure.

Abstract: This system for guiding a person to a destination situated in a predetermined area comprises a fixed guidance station (10) comprising: means (12) for reading a code associated with a destination; wireless communication means (14) having a standby mode and a low electrical power consumption mode for: sending a request including said code associated with a destination and said indication of the position of said fixed station to a route determination device (20); and receiving a response including that route; and means for conveying said route to the person.

Abstract: Service areas are defined in a wireless telecommunications network, each area being defined by the addresses of fixed stations for accessing the network situated in that area. The access devices to those services obtain the file defining the areas and a file defining the services in the areas from a peer-to-peer network. They determine the area in which they are located from the address of the fixed station by which they are connected to the wireless network.

Abstract: A method for sending electronic messages via a messaging system that includes receiving, by a group messaging server, a message sent from a remote user's terminal; and transmitting the message by the group messaging server to the terminals of users in a group of predetermined users according to transmission rules predetermined by the user at whose initiative the group of users is created.
