Abstract: Techniques, apparatus and systems for information collecting and decision making based on one or more tiered networks of sensors and communication nodes for security monitoring and warning, disaster warning, counter-terrorism, and other applications associated with information collecting and decision making. In implementations, the one or more tier networks in the plurality of different tier networks include network nodes at roadway intersections; the sensors include automatic license plate recognition sensors to obtain data on vehicle license plates; and the response produced by the processing mechanism includes controlling traffic controllers to alter traffic routes at one or more locations.

Abstract: A sprinkler is disclosed for improved flow characteristics. The sprinkler has a sprinkler head rotatably supported for distributing water and defining a flow channel for directing water flow therethrough with reduced head loss. The flow channel has a smoothly tapered portion for receiving water and channeling the water towards an outlet in communication with a first nozzle for distributing the water. The flow channel with reduced head loss produces a greater throw distance at a lower trajectory with a lower flow rate and pressure. The flow channel may be formed within a flow channel member positioned within the sprinkler head. The flow channel member may cooperate with the sprinkler head to define a cavity allowing water to pass through the cavity from the flow channel for emission from a plurality of other nozzles.
