        Concept:</p>
        <p id="eua216" class="western" style="margin-bottom: 0.2in;">The SimCrossing (SC)
        is based one several messages exchanged between the object (Object),
        the actual sim (OriginSim) and the next sim (TargetSim). The main
        exchange are located in the  HandOverArea (HOarea) located on the
        OriginSim. This area is computed by the viewer for each TargetSim
        (maximum 4 ).
