A classification count adjustment system for adjusting a count estimate of items in a dataset D classified into a class is disclosed. The base station can include multiple radio devices that can be configured to communicate with user devices using different protocols and different frequencies. If this call is the first time the caller has ever called, the caller would be presented with an audible listing of listening choices that would include but not be limited to the latest news, the weather, financial headlines, or a selection of music stations. In further aspects, the user interface is adapted to accept user input expressing a desire whether to allow a potentially altered spatial dimension to change, and the design engine preferentially maintains some potentially altered spatial dimensions while altering other potentially altered spatial dimensions based on the expressed preference. The source andor a drain are in proximity to the first edge or the first and second edges of the at least one gate. The frame assembly can be provided as a single-sheet preform and can be self-standing.
