Embodiments of the present disclosure provide a method and device for recognizing a state of an electrical device. The method includes obtaining an image of the electrical device in a field, wherein the electrical device is disposed on a plane of a predefined polygon in the field; obtaining an original appearance image of the electrical device in the field by recovering the predefined polygon in the image to an original appearance of the predefined polygon; and determining the state of the electrical device based on the original appearance image of the electrical device in the field.

Method and device for recognizing states of electrical devices

A radiofrequency transmission line configured so as to allow a radiofrequency electrical signal to be transmitted between a first end and a second end, the transmission line including a main conductor and a ground plane electrically connected to an electrical ground of the transmission line. The ground plane includes a set of portions that are connected in series between the first end and the second end and a set of second capacitors, the set of portions including a set of second portions, each second capacitor being inserted between two contiguous second portions.

Radiofrequency transmission line, device including such a transmission line and system for monitoring an installation including such a device

An electrical device includes an electronic control unit including a radio communication interface provided with a planar internal radio antenna housed inside a first housing of the electrical device and including a first radiating element. The electrical device furthermore includes a movable coupling element connected to an external radio antenna, the coupling element being provided with a second radiating element and being able to be moved between a position connected to the housing of the electrical device and a position disconnected from the housing. In the connected position, the coupling element is positioned facing the internal radio antenna while being separated therefrom by an electrically insulating element, the second radiating element being coupled to the first radiating element so as to receive electromagnetic radiation emitted by the first radiating element.

Wireless communicating electrical device and electrical enclosure comprising this electrical device

A method of radio communication in a system including a plurality of communicating modules, each communicating module being able to obtain at least one measured physical value and to transmit a message encapsulating at least one measured physical value to a hub device according to a given radio communication protocol, the sending of the message being performed during a communication time interval, defined by a start instant and an end instant, a waiting time separating two successive communication time intervals of one and the same communicating module. For each communicating module of the plurality of communicating modules, the waiting time is calculated as a function of an updated counter of the communicating module as a function of a receipt of an acknowledgement message originating from the hub device.

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

Electromagnetic antenna reconfigurable by electrowetting

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.
