A virtual environment browser holds a number of clip-in files defining guide characters\u2014locally generated visual aids to navigation that appear within a generated image of a virtual environment and follow a user’s input navigational commands to provide an advance cue as to the effects of an input command. At least one of the magnetic coding elements has a grid-shaped magnetic region which is formed by a plurality of mutually parallel grid strips made of magnetic material which respectively have a magnetic anisotropy. The base station controller controls one or more base stations. The micro-current generators facilitate delivery of the benefit agents by iontophoresis, or directly affect treatment by delivery of micro-current to the skin. The at least one control unit controls a power output via a pulse width modulation of a pulse duration of the first operating state relative to an operating period. The pivot element is likewise essentially made from biocompatible metal and attaches directly to the moving forceps leg.
