Patent number: 11721880Abstract: A laminated glazing panel includes an outer pane of glass and an inner pane of glass, the inner pane of glass being laminated to the outer pane of glass by a thermoplastic interlayer. The panel further has an antenna structure including: (a) a feeding structure comprising at least one ground conductor and a signal conductor, the least one ground conductor being electrically isolated from the signal conductor by a gap, and (b) a radiator, fed by the feeding structure and electrically connected to the signal conductor. The panel also has a connector, to power the antenna structure, that includes a further conductor connected to the signal conductor, and at least one conductor connected to the at least one ground conductor. The radiator, the signal conductor and the extremity of the further conductor are provided on at least one of the surfaces of the inner faces of the glass panes.Type: GrantFiled: March 29, 2019Date of Patent: August 8, 2023Assignee: AGC GLASS EUROPEInventors: Xavier Dardenne, Dan Lis, Yvain Cornet, Shimo Kenichiro, Bart Verbeeren

Patent number: 9608694Abstract: A method for locating an impairment within a telecommunication line may include determining measurement data related to the telecommunication line and estimating a location of the impairment depending on the measurement data. The measurement data includes crosstalk data including at least one transfer function element of a crosstalk matrix. The transfer function element characterizes a crosstalk transfer function from the telecommunication line towards the at least one further telecommunication line, and the method includes detecting oscillations in the crosstalk transfer function.Type: GrantFiled: September 12, 2012Date of Patent: March 28, 2017Assignee: Alcatel LucentInventors: Xavier Dardenne, Benoît Drooghaag

Patent number: 9485353Abstract: The present invention refers to a method and device for detecting a bridged tap within a telecommunication line. In order to reliably detect bridged taps of different types, in particular wire pair bridged taps and single wire bridged taps, and/or to determine a type of each detected bridged tap the method includes determining first transfer function data that characterize an actual transfer function of the telecommunication line; detecting the bridged tap depending on the first transfer function data; simulating the telecommunication line based on a result of the detecting; and identifying the type of the bridged tap by comparing results of the simulating with the first transfer function data.Type: GrantFiled: May 22, 2013Date of Patent: November 1, 2016Assignee: Alcatel LucentInventors: Xavier Dardenne, Benoît Drooghaag

Patent number: 9178986Abstract: The present invention refers to a method (45) for identification (53, 73) of an impairment (59) within a telecommunication line (13), the method (45) comprising determining (49) first measurement data (Hlog) that characterize a transfer function of the telecommunication line (13). In order to provide a method (45) for identification of an impairment (59) within the telecommunication line (13) that can be applied on the telecommunication line (13) without interrupting the operation of the line (13) and that can easily be implemented in connection with existing system such as existing DSL systems, it is suggested that the method (45) further comprise determining (55) at least one periodicity interval (?f1, ?f2) of oscillations of the transfer function and that the impairment (59) be identified depending on said determining (55).Type: GrantFiled: November 19, 2012Date of Patent: November 3, 2015Assignee: Alcatel LucentInventors: Xavier Dardenne, Benoît Drooghaag
