Abstract: A mobile device may use one or more outlier detectors to detect likelihoods that an outlier condition exists for a satellite positioning system (SPS) position fix. In some implementations, an outlier detector may compare a computed position fix to an element of assistance data to generate an outlier likelihood.

In some implementations, a computed reliability of the position fix may also be considered in making a recovery decision.

Abstract: A filter for use in a washing appliance is disclosed. The filter includes an inlet, an outlet, a filter chamber and a mesh strainer placed between the inlet and outlet. The mesh strainer strains water or liquid flowing into the filter as the water flows into the inlet and out of the outlet. The mesh strainer filters out particulate matter from the flow through the filter. The liquid flowing into the filter flows across the mesh to clean the filter and dislodge at least some of the particulate matter trapped in the mesh. The filter chamber includes at least one baffle within it. The baffle divides the filter chamber into an upper portion and lower portion. The particulate matter washed off collects in the lower portion of the filter chamber due to rotational flows created in the filter due to the filter chamber boundaries and the baffles.
