There is disclosed a meanderline loaded antenna formed by applying a conductive ink or other conductive material to a flexible substrate. In addition to the foregoing, other method aspects are described in the claims, drawings, and text forming a part of the present disclosure. Also provided are methods for identifying and imaging spatial distributions of time variable signals generated from dynamic systems. The transport means may be constructed in the form of a carriage comprising two motorized wheelsets. The snapshot module receives and processes OSD and other commands from the file system or a service processor, creates an original object and a mirror object in an OSD, and initiates a snapshot operation in an OSD.
