Abstract: A method for filtering a set of records on a user interface involves displaying a set of records, each record of the set comprising a first field and a second field; removing, from the displayed set, one or more records according to a filter of the first field, thereby leaving a subset of the set of records displayed; displaying filters for the second field; and for at least one of the displayed filters, visually indicating that, due to a currently-applied filter, the at least one displayed filter does not apply to any of the records of the subset.

Abstract: A snow skate is disclosed which provides improved control and skate-like performance, particularly on hard-pack or icy surfaces. The snow skate has edges which increasingly project from the central flat region of the ski to the forward area. Preferably this is achieved by making the base increasingly concave forward and rearward from a central generally flat region.
