The location of an interface is detected by image processing steps, which may comprise the steps of “spoiling” the image, “diffusing” the image, “edge detection”, “edge linking”, “region-based confirmation”, and “interface calculation”. “Spoiling” reduces the number of pixels to be examined preferentially on orthogonal axis oriented with respect to the expected location of the interface or phase boundary. “Diffusing” smoothes out small oscillations in the interface boundary, making the location of the interface more distinct. “Edge detection” computes the rate of change in pixel intensity. “Edge linking” connects adjacent maxima. “Region-based confirmation” creates a pseudo image of the regions that qualify as distinct. “Final edge calculation” uses the points where the shade changes in the pseudo image, averages the radial displacement of these points for the interface position.

Abstract: A new automatic pool skimmer cleaning system includes an auto clean skimmer, debris basin, and pump. A check valve line runs from the side of the skimmer to the debris basin. When the pump is run, suction on the check valve line opens the valve and allows water and accumulated debris in the skimmer to flow into the debris basin, where debris is caught in a debris basket. The filtered water is returned to the skimmer. Debris accumulates in the debris basin over a season and is occasionally emptied. The system's pump operates independently of the pool's filtration system and is run when the filtration pump is cycled off. For vacuuming, a vacuum attachment connects to the check valve line and allows vacuumed water to be passed directly through the debris basin and debris basket and then returned to the filtration system, avoiding the need to backwash the filter.

Abstract: A visual bilgewater quality indicator for use in a bilgewater filtration system which includes a filtration stage for removing oily contaminants. The quality indicator utilizes one or more filtration status chambers which are provided with a fluorescent or phosphorescent dye or pigment treated filtration media.

Abstract: An oil filter assembly has a bypass valve and a cover formed with an orifice. In order to provide a simple contamination indicator for the oil filter, there is provided a deflection device that deflects an oil jet emerging through the orifice when the bypass valve is open on the outside of the cover.
