Abstract: A system and method of improving communications is provided. A gateway is communicatively coupled to an end terminal through an unmanned air vehicle (UAV), wherein a first link communicatively couples the gateway to the UAV, and a second link communicatively couples the UAV to the end terminal. At least one of the gateway and the UAV is configured to determine a signal quality on at least the first link between the gateway and the UAV in a first direction. If the signal quality exceeds a predetermined threshold, a received packet is encoded at the gateway for processing by the end terminal. The packet is further tagged with an indicator that the packet should bypass forward error correction (FEC) at the UAV.

Abstract: A method and apparatus for disinfecting the interior of pipelines and conduits, particularly water mains. Ozone is utilized as the disinfectant vehicle to neutralize microbial contamination of the conduit. An ozone generation system includes a venturi injector for introducing ozone into pressurized water to provide a treating solution that is introduced into and that flows along a predetermined length of the conduit to be treated. The ozone concentration is regulated to maintain an ozone residual at the conduit outlet of about 0.2 mg/L to about 0.3 mg/L for a time sufficient to assure the desired level of disinfection of the conduit interior. Carbon dioxide can be added to improve the ozone residual stability and the effectiveness of disinfection. The apparatus is transportable and can be carried by a transportation vehicle, such as a truck or trailer, for on-site disinfection of pipelines at varying sites.
