Abstract: An automatic multi-air bag pneumatic inflation system for a trailer is also disclosed. The inflation system includes a system control unit coupleable to an air supply for controlling the flow of pressurized air in the pneumatic inflation system. The system control unit comprises an inlet for coupling to the air supply with an on/off valve for providing a flow of air, a primary regulator in communication with the flow of air and the on/off valve, an inflation pressure tank in communication with the flow of air and the primary regulator, a control valve in communication with the inflation pressure tank and/or primary regulator, and used to control the air flow, a function selection valve for selecting between inflation and deflation, and an outlet. A plurality of fill stations are fluidly coupled to the system control unit. One or more fill stations of said plurality of fill stations are fluidly coupled to an air bag for inflation and deflation thereof.

Abstract: A power line communication system including a plurality of intelligent devices in communication with a power line and operable to monitor energy usage at a site and communicate usage data onto the power line, and a controller also in communication with the power line, wherein each intelligent device maintains a routing table identifying a first set of other intelligent devices downstream of it relative to the controller that it can communicate with directly and identifying a second set of other intelligent devices downstream of it relative to the controller that it can communicate with through one or more of the first set of other intelligent devices.
