Abstract: A method for transmitting data collected by at least one sensor to a monitoring device. The method includes, upon acquisition of a new piece of data by the at least one sensor, acts of calculating a deviation indicator indicating a deviation between the value of the new piece of data and a value predicted for this piece of data by a prediction model representative of previously acquired data, and transmitting the new piece of data to the monitoring device when the deviation indicator is higher than a threshold. Also provided are a monitoring method on a monitoring device, a terminal implementing the transmission method and a server implementing the monitoring method.

Abstract: The invention concerns a method for qualifying an alarm among the alarms stemming from a first supervision system supervising the activity of an individual, the system being adapted to compute an activity index that is representative of the activity of the individual, alarms being triggered by the supervision system in the event of a drift in the activity index, a drift corresponding to a difference in the value of the index in relation to a reference value, the method being such that it is implemented in a management server connected to at least one second supervision system, and that it has, on reception of an alarm triggered by the first supervision system, steps of obtainment of a drift in the activity index of the at least one second supervision system, comparison of the drift in the activity index of the first supervision system and a value that is representative of the drift in the activity index of the at least one second system, and qualification of the alarm according to the result of the comparison

Abstract: One inventive aspect relates to a method of constructing a graph representing a building (BAT) in which a person (U) moves. In one inventive aspect, the method is adapted to receiving information about the movement of the person in the building over a period of time, the information being collected and transmitted by a portable device (D) associated with the person (U), and in constructing at least one branch of the graph from received movement information. One inventive aspect also provides a method of remotely tracking the activity of a person in a building as a function of the constructed graph. One inventive aspect also provides a server (S) implementing the method of constructing a graph.

Abstract: A method of transferring communication streams, including establishing a first stream via a first communication path between a first terminal and a second terminal, opening a second communication path between the second terminal and the first terminal, sending to the first terminal, via the second communication path, a request to establish a communication stream between the first terminal and a third terminal via a third communication path, and comparing respective capabilities of the first terminal and the third terminal to determine whether it is possible to establish a communication stream between the first terminal and the third terminal, and in the affirmative, interrupting the first stream and establishing a communication stream, between the first terminal and the third terminal.

Abstract: The invention relates to a method of constructing a graph representing a building (BAT) in which a person (U) moves. In the invention, the method is adapted to receiving information about the movement of said person in the building over a period of time, said information being collected and transmitted by a portable device (D) associated with said person (U), and in constructing at least one branch of the graph from received movement information. The invention also provides a method of remotely tracking the activity of a person in a building as a function of the constructed graph. The invention also provides a server (S) implementing the method of constructing a graph.

Abstract: The invention relates to an electromagnetic antenna that comprises a radiating element composed of a first, electrically conducting, fluid substance (F1) sitting on a first element (S1) and of a second fluid substance (F2) sitting on a second element (S2), the first fluid substance (F1) being in contact with the second fluid substance (F2), said fluid substances being immiscible and said first and second elements being electrically conducting and electrically isolated from one another.

Abstract: A reconfigurable electromagnetic antenna which comprises a radiating element consisting of a fluid substance that conducts electricity, the volume of the fluid substance being variable and that also comprises a matrix of electrodes on which the fluid substance is moved by electro-wetting. The properties of the antenna in frequency, polarization or even in radiation pattern evolve dynamically. The reconfiguration of the antenna in frequency, in polarization or in radiation pattern is continuous and reversible.

Abstract: Predefined electrical signals, produced by an electrical equipment in the building during a change of electrical operating state of said equipment, are detected on the building's power supply system. By analyzing each detected electrical signal, tracking data is generated including information relating to the date of detection, the electrical equipment originating the signal and the corresponding change in electrical state. At least one parameter representative of the activity carried out by said person is determined, in the form of a probability of an activity or a type of activity being carried out, based on tracking data generated during a predefined period of time.

Abstract: A videoconferencing system breaks the isolation of teleworkers by recreating relational situations between the teleworkers and other employees from the same company as if the parties were conversing in the same office. Each person participating in the videoconferencing always receives animated images of all the other participants via a central server and can select the image of at least one other participant with whom an audioconference, within the videoconference, is to be established. The central server only retransmits audio data from each audioconference participant to the other audio conference participants, with an identifier for each participant.
