Abstract: A filter element analysis system for analyzing a filter element within a vehicle, the system including various filter sensors so as to provide information regarding various filter element parameters, a locator which configured provide vehicle position information such that conditions regarding the vehicle environment can be tracked and correlated to the location, as well as a means for transmitting information to a remote server for analysis and tracking of the filter element information with regard to environmental conditions such that a filter element status, remaining filter life, or particle load and replacement timeline can be calculated and updated so as to provide more accurate predictive models of the filter element conditions. As well as provide alerts regarding the need and scheduling of replacement or cleaning of a particular filter element.

Abstract: Disclosed is a data storage, display, and editing system whereby a large database may be accessed through a series of views, each view being defined by metadata. The metadata includes relationships to other views that may be used for any purpose including navigation from one view to another. The relationships establish a tree of related views that may be traversed in order to capture data that may be taken off line. The relationships may be used to reconstruct records to be committed to a database. The views and relationships allow useful data to be stored for use off line with a minimum of unnecessary data. The relationships are particularly applicable to database applications that are implemented on handheld or other small, remote computing devices.
