Abstract: In some implementations, a node may receive one or more communications, wherein the one or more communications include time information, and wherein the one or more communications are associated with a peer-to-peer network. The node may identify a primary node associated with the peer-to-peer network based on an indicator included in a communication, from the one or more communications, that is associated with the primary node. The node may synchronize a time stored by the node based on time information included in the communication that is associated with the primary node. The node may receive an indication that the node has successfully joined the peer-to-peer network based on synchronizing the time to the time information. The node may selectively update the time stored by the node based on a reference time included in periodic data transfer communications that are associated with the primary node.

Abstract: A mixer includes a fresh air tube defining a passage having an inlet receiving conditioned air from an air conditioning pack. The fresh air tube includes an outlet providing mixed air to a cabin of the aircraft. An outer tube at least partially surrounds the fresh air tube and receives recirculated air from the cabin. A circumferential corrugation in the fresh tube forms multiple lobes in the fresh air tube fluidly connect the outer tube to the fresh air tube. The warm recirculation air surrounds the portion of the fresh air tube to heat it preventing ice from forming. The warm recirculation air entering the fresh air tube through the lobes homogeneously mixes with the conditioned air from the pack to provide a uniform mixture of air within the fresh air tube, which further ensures the prevention of ice build up.
