From Memory Alpha, the free Star Trek reference

M. Fincke was an Earth Starfleet lieutenant who served as an engineer on board Enterprise in 2161.

During the rescue mission for Commander Shran's daughter Talla, he served in main engineering where he was asked by Commander Tucker if all deuterium filters are free. He responded that three are done and was ordered to free the others quick. (ENT: "These Are the Voyages...")
