Methods, apparatuses and systems allowing for dynamic bandwidth management schemes responsive to the state of a plurality of access links in redundant network topologies. The method includes following steps: providing a substrate having patterned transparent electrode thereon; and forming an alignment layer on the surface of the transparent electrode. The trench has sidewalls and a base, with the base comprising monocrystalline silicon. The length of the top plate part A2 in the conveying direction is set shorter than the chain pitch. Wherein the unique power distribution architecture is possible by the formation of a plurality of ink vias in the heater chip which provides for an increase in the chip surface area available for electrical connectivity. The containment border is substantially transparent and is substantially flush with the surface of the slide or plate for containing the liquid, histological or other biological sample disposed thereon and thereby preventing spreading or migration of the sample across the slide or plate.
