Systems and methods for neutralizing pathogen-contaminated mail pieces via variable frequency microwave processing are provided. A movable member is movably received in the second through hole and includes a driving section and a connection section. At least one tungsten plug is electrically connected to at least one electrically conductive interconnect line. The system further includes a configuring tool executable on a server computing device. Consequently, the impact value and the fatigue strength are inhibited from decreasing. The method comprises analyzing an image of a form to detect object demarcations in the form.
