A foreign substance removing apparatus that can provide the desired vibration amplitude to a light transmitting member, without using a large driving voltage. In a preferred embodiment, a three-dimensional unstructured finite element mesh representing a physical system is extruded in the time dimension. This is in contrast to passive operations of conventional application servers that allow browsers to actively access application servers for screening, leaving the application servers and other associated entities vulnerable to possible computer hackers. Spatial data is compiled related to the display features and the corresponding image features. The insert can be resilient to avoid crushing of rail members and resist impact loads.
