The television series and films do not go into great detail about transporter technology. The "" claims that the devices transport objects in real time, accurate to the quantum level. The episode "Realm of Fear" specifies the length of a transport under unusual circumstances would last "... four or five seconds; about twice the normal time". This calculates the length of a typical transport as between 2 and 2.5 seconds and possibly less. Heisenberg compensators remove uncertainty from the subatomic measurements, making transporter travel feasible. Further technology involved in transportation include a computer pattern buffer to enable a degree of leeway in the process. When asked "How does the Heisenberg compensator work?" by "Time" magazine, "Star Trek" technical adviser Michael Okuda responded: "It works very well, thank you."
