A system that communicates information is described. In particular, the universal media server has one or more virtual AV inputs, each virtual AV input corresponding to an IP-based AV source device having a corresponding IP source address and configured to receive IP-based AV data from the IP-based AV source device on the at least one IP input. Damping pads are mounted on the ends of the legs to press against the surfaces of the rotor being machined. The model is then formed from the preserved logic.
