A method of managing a content routed network, involves distributing published documents through said network for delivery to subscribers; maintaining data logs pertaining to said published documents at different points in the network; and correlating the data logs to obtain information about the operation of the network. An application may be executed in the first mobile device such that the application enables the first mobile device to communicate with a second mobile device over a wireless ad hoc network. The master piston has an adjustable dead band. In another embodiment, the composite particles are included in a powdered beverage mix wherein the powdered beverage mix itself provide the initial sequential change followed, by an appropriate delay, the second sequential change; further sequential changes can be provided, if desired, by providing additional layers with the appropriate optical andor organoleptic ingredients therein. The method further forms an offset spacer layer over the depleted sidewall layer and over exposed surfaces of the bottom layer. Next, a stage is inserted between the first and second cameras so that the first camera takes images of a second part held on the stage, and the second camera of a stage reference mark thereupon.
