Abstract: A filter simulation system that includes a simulation filter (11) with a sensor (13) such that the volume of air passing through the filter can be determined. There is also a control means (16) with stored data relating to level of protection the simulation filter provides against a simulated toxic substance. In this way the filter simulation system can determine whether a correct simulation filter has been selected by a user and whether or not that filter has expired, in which case a dead or incapacitated result can be indicated. In the event of expiry a simulation end of life service indicator (ELSI 22) may be activated.

Abstract: A system, method, service and media for managing both supplier-owned and non-owned manufacturing asset types utilizing a supplier model of a product which goes across the manufacturing asset types. The invention maps the model to instances of the asset types and uses a network to control and monitor the assets. The monitoring and control occur according to the model, rules and services and does not require the vendors of non-owned manufacturing asset types to change their manufacturing execution systems.
