Network cluster printing without external services, additional hardware or unique printer drivers is described. Realistic prior probability distributions of pertinent variables are permitted for the locations of stations, the speed of signal propagation, and errors in measurements. The scented compound sample is placed within a cabinet having an enclosed sample chamber which is connected to an upward facing sample tube. Upon determining that the criterion for launching the first meta-application is satisfied, at least one of the plurality of applications is programmatically invoked. One embodiment of the invention extends the standard VLAN bridge model to provide a mechanism that is suitable for use within an AP. The damper mechanism includes a vibration absorbing mechanism and at least one actuator that is controllable to affect the torsional vibration absorbing characteristics of the vibration absorbing mechanism.
