An apparatus for servicing a field device from a remote terminal, wherein the field device has an onsite displayservicing capability and is connected to a fieldbus of process automation technology. Specifically, the hydrogel has a crosslinked gel structure and a biologically active component incorporated into the crosslinked gel structure, the biologically active component being capable of converting glucose into a compound having potentiometric activity. The hybrid dual configuration transmission may be operated utilizing exclusively the electric motor, exclusively an engine, or any combination of the electric motor and engine. The ablation probe further comprises a porous structure that is associated with the distal end of the shaft in fluid communication with the lumen. A source electrode and a gate electrode are formed on the source electrode contact layer. Fibers with positive group velocity dispersion and self phase modulation are advantageously employed with the optical sources.
