System and method for measuring retentate in filters
A system and method for determining loading of a filter having a first dielectric constant with a material having a different dielectric constant, is disclosed. The filter is contained within a metallic container forming a microwave cavity, and microwave or RF energy is created within the cavity and changes in the cavity microwave response are monitored. The changes in cavity microwave response are related to filter loading. In a preferred embodiment, the microwave energy includes multiple cavity modes thereby allowing determination of spatial distribution of the contaminant material loading. In one embodiment, the microwave cavity response includes a shift in frequency of a resonant mode. Alternatively, the microwave cavity response includes a shift in quality factor Q of a resonant mode. The microwave cavity response may include a shift in amplitude or peak width of the microwave's signal at resonance.

A vehicle pedal assembly with a rotatable pedal. A hysteresis assembly includes a friction device and plunger, and first and second springs that are all separate and decoupled from each other and the pedal. The first spring exerts a force against the friction plunger that forces the friction device into frictional contact with the housing to generate and transfer a resistance force to the pedal. The first spring also exerts a force against the pedal when a foot force is removed from the pedal to return the pedal to idle with and without the movement of the friction device and without the force of the second spring. The second spring exerts a force against the friction device when the foot force is removed to return the pedal to idle without the force of the first spring. Barriers block the entry of debris into the housing.
A duplex filter includes a block of dielectric material with top, bottom, and side surfaces and first and second spaced-apart sets of through-holes.
