Earth-boring tools include one or more cutting elements having at least one grading feature positioned a known distance from an initial working surface of the cutting element. Users can choose to learn how to perform a specific skill in the language and learning style that fits their needs and schedule. The three dimensional graphical figure is bent responsive to rotation speed of a viewpoint base; and stretched or compressed responsive to viewpoint translation speed. A transparent cover screws onto the base to protect the instruments stored therein while allowing them to be displayed. If the user equipment is in connected mode a network base station may select a set of mobility trigger parameters to be used for performing handover decisions based on a determined speed range of the user equipment.
