A fiber optic cable having at least one interface being formed by a plurality of adjacent support members. The containment wall extends over an overall area and the porous openings provide an open area through which the feedstock flows as the feedstock passes through the containment wall, and the open area is at least about twenty-one percent of the overall area of the containment wall for enabling a concomitant increased volumetric flow of feedstock through the containment wall. In some embodiments, sidewalls of tube segments connected together are substantially parallel to one another at or near the connection region. The aid is re-arrangeable into a walk supporter or walker, a sitting transporter and a standing transporter by the removable fitting of a seat and a standing platform respectively. The command management component may be configured to generate mapping information from the information received via the user interface. The opposite end of air supply tubing is connected to one or more air nozzles.
