Phase inducer

A phase inducer was a technological component of transporter and warp drive systems. 

In 2294, after surviving the crash of the USS Jenolen, retired Starfleet officer Montgomery Scott devised a method to save himself and his fellow survivor Matt Franklin, by feeding power to the transporter from the auxiliary systems, disabling the rematerialization subroutine, connecting the phase inducers to the emitter array, and locking the pattern buffer into a continuous diagnostic cycle. This effectively allowed Scott and Franklin to survive in a state of suspended animation in a dematerialized state, until they could be rescued. This innovation proved successful for Scott, who was rescued by the crew of the USS Enterprise (NCC-1701-D) 75 years later, but Franklin's pattern had degraded 53 percent due to the failure of one of the inducers. 

In 2371, while engaged in combat with a number of Jem'Hadar fighters, the USS Defiant (2370) sustained damage to the warp drive, which proved difficult to repair due to the fact that T'Rul, Starfleet's Romulan adviser, was unable to get the phase inducers to align with the ODN matrices. 

In 2371, Deep Space 9's chief of operations Miles O'Brien was seriously injured when, while attempting to re-route a phase inducer, a plasma conduit blew out, resulting in unconsciousness and a mild case of radiation poisoning. 

In an alternate future, during combat with a fleet of Klingon attack cruisers, the Federation starship Pasteur'' sustained damaged to it's phase inducers, which Geordi La Forge was unable to to bring back online, making an escape at warp impossible. The timeline in which these events occurred was later negated when Jean-Luc Picard was able to prevent the formation of an anti-time eruption from traveling back in time. ''
