A multilayer film for ostomy and bowel management applications includes a barrier layer comprising at least about 90% wt. The serial driving device includes a digital-to-analog converting unit, an analog buffer, a shift register, and an output buffer unit. The time of flight of light signals from the light source to the actuated portion of the detector is calculated for all scanning directions, to enable a three dimensional image of the object to be constructed. A slave controller controls a slave arm mechanism, according to the corrected master motion information. The pivoting of the tracking assembly positions the tracking assembly at an angle with respect to the support member, such that when the alignment mechanism is activated the angle of the tracking assembly is modified, thereby adjusting a flow path of the web of material in the packaging machine. The method and apparatus include training, in which a model is generated upon training interactions and available tagging information, and run-time in which the model is used towards sectioning further interactions.
