Patent number: 11641239Abstract: Methods and systems capable of launching signal-carrying transverse electromagnetic waves onto a transmission line in the higher voltage region of the transmission distribution network. Such methods and systems may include a surface wave launcher located in the higher voltage region, a network unit located in a lower voltage region, and an arrester separating the surface wave launcher and the network unit, the arrester preventing voltage from arcing over from the higher voltage region to the lower voltage region where the arrester provides the signal to the surface wave launcher.Type: GrantFiled: June 23, 2021Date of Patent: May 2, 2023Assignee: ARRIS Enterprises LLCInventors: David B. Bowler, Shaoting Gu, Xinfa Ma, Clarke V. Greene, David Grubb, III, Samuel Francois, Lawrence M. Hrivnak, Bruce C. Pratt, Theodore A. Colarusso, Thomas F. Kister, Robert Noonan, Vincent T. Lucarini, David F. Hubbell

Patent number: 11095369Abstract: Disclosed is a device communicably coupled to a power transmission line and capable of launching transverse electromagnetic waves onto the transmission line. The waves propagate data received from a data source connected to the device through a center conductor surrounded by a shield conductor. The device may include a reflector and a coupler adjacent to each other, the reflector electrically connected to the shield conductor and the coupler electrically connected to the center conductor at an unshielded connection point, wherein time-varying E-fields between the reflector and coupler are caused by the data received from the data source, and induce a transverse magnetic wave that propagates longitudinally along the surface of the transmission line.Type: GrantFiled: March 9, 2020Date of Patent: August 17, 2021Assignee: ARRIS Enterprises LLCInventors: David B.
