Abstract: Techniques are disclosed for providing robust, comprehensive measurement and analysis for optimizing efficiency of compressed air systems. The techniques provided can be implemented, for example, in a network appliance local to the target compressed air system, and/or in a server configured to remotely monitor and evaluate the target system. On-site data logging as well as on-site or remote data analysis can be enabled, along with onboard data consolidation. Meters (e.g., airflow, air pressure, power, and/or acoustic) are deployed at the target system and provide data upon which the analysis is based.

Abstract: A method of making a plurality of concentric ring cuts in a pliable device such as an elastomeric seal, by rotating the device at a speed to generate a desired centrifugal force and cutting into the rotating device with a knife while flushing the knife and elastomeric device to produce a device having one or more sets of concentric rings with each set comprised of one or more rings.
