Abstract: A diagnostic method of electrical equipment which includes a processing unit, an internal microphone, and electrical components other than microphones or speakers, the diagnostic method including the steps of acquiring a received audio signal produced from an ambient sound signal, by the at least one internal microphone or by the at least one external microphone, producing monitoring parameters from the received audio signal, which are representative of an interfering sound signal comprised in the ambient sound signal and emitted by at least one of the electrical components, and detecting a sound anomaly resulting from a failure of at least one electrical component of the electrical equipment from the monitoring parameters.

Abstract: A detection method, performed prior to applying a voice recognition function to a voice signal uttered by a user and picked up by a set-top box, includes the steps of: verifying that the television set is switched on, and if not, producing a first command for switching the television set on; verifying that the set-top box is an active HDMI source of the television set, and if not, producing a second command for causing the set-top box to become the active HDMI source of the television set; while the television set is switched on and the set-top box is the active HDMI source of the television set, producing a request to start the voice recognition function.

Abstract: A method is provided for installing a new node in a wireless home network having a client network and includes a node able to form a mesh network. A connection of a new node to the client network supplied by the home network node is detected, and an identifier of a client device that is connected to the client network is received. If the client device is known to the home network: the new node is notified that the client device that is connected to the client network must be disconnected from the client network; a connection of the client device to the client network supplied by the node of the home network is detected; and identifiers of the mesh network are transferred to the new node if the connection of the disconnected client device to the client network supplied by the node of the domestic network is detected.
