Abstract: A filter remaining capacity detection system is presented that includes a parameter retriever that retrieves parameter information for an atmosphere around the filter. The system also includes an adsorption estimate generator that, based on the parameter information retrieved, solves a set of controlling equations to generate an adsorption estimate. The controlling equations are a set of mass and energy balance equations. The system also includes a remaining capacity detector that, based on the adsorption estimate, generates a remaining capacity estimate. The system also includes a signal generator that generates a signal if the remaining capacity estimate is below a threshold.

Abstract: A filter predicted capacity estimation system is presented that includes a parameter retriever that retrieves parameter information for an atmosphere around the filter. The system includes a parameter trend retriever that retrieves historical parameter indications from a database. The system also includes a real time capacity estimator that, based on the parameter information retrieved, and solves a set of controlling equations to generate an estimated capacity. The controlling equations are a set of mass and energy balance equations. The system also includes a parameter projection generator that, based on the historic parameter indications, generates a future parameter trend for the atmosphere and filter use. The system also includes a predicted capacity estimator that, based on the adsorption estimate, and based on the future parameter trend, generates a predicted capacity estimate. The system also includes a signal generator that generates a signal if either the estimated capacity or the predicted capacity estimate is above a threshold.
