Editing Transporter (section)

==Special operations==
'''Disabling active weapons'''

By the 24th century, the transporter had the capability to disable any active weapon during transport. This could be accomplished by removing the discharged energy from the transporter signal (TNG|Datalore); by deactivating the weapon (TNG|The Most Toys); or by removing the weapon from the matter stream entirely so its holder rematerialized without it, which could be accomplished by implementing Transporter protocol 5 (DS9|To the Death).

'''Connecting two transporters'''

When necessary transporters could be bridged, Federation vessels could activate other Federation vessels' transporters remotely. This meant that two transporters could be connected to each other in the event beaming was not possible due to ionic or some other type of interference.

The transport duration was twice as long and the sequence differed from a normal transport. First a remote link to the other transporter had to be established, then the system interlock needed to be engaged and the pattern buffers of both transporters were synchronized. When the phase transition coils were in stand-by mode energizing could commence. 

A side-effect of this form of transport might be that the person who was beamed might feel a slight tingling due to static. (TNG|Realm of Fear)

'''"Intra-ship Beaming"'''

In the mid 2260s, beaming from a transporter pad to a location within the same vessel was a very risky proposition.  The limitations of the technology at that time made it highly probable that any error would result in the subject rematerializing within a bulkhead, deck, or other structure.  (TOS|Day of the Dove)  Oddly, this procedure was used without incident a century earlier.   (ENT|Chosen Realm)   Commander Riker and Tasha Yar used this operation during a rescue.  (TNG|Symbiosis)  When cargo instead of passengers was beamed aboard, Riker tells Yar to beam the cargo to the hold without a second thought.

:''Why this would be the case is not known.  A technology capable of transporting a subject over thousands of kilometers without error ''should'' be able to do so over a few dozen meters easily, though one could speculate that the emitters are focused away from the ship, as shown in the technical manuals.''

:''From the writing standpoint of the episode itself, though, if such capability ''did'' exist, then it would have been an easy matter to free the trapped crewmen in the lower decks.''

'''"Site-to-site" transport'''

The earliest example of site-to-site transport carried out by Federation personnel occurred in 2286. A HMS Bounty|Klingon vessel stolen by the crew of the late starship ''Enterprise'' had site-to-site transporter capabilities. (Star Trek: Insurrection)

By 2364, limitations in pattern buffer and targeting scanner technology had been sufficiently overcome that it was now possible to transport from one location directly to another without the need to re-materialize the subject in between.  This operation was enabled and controlled by the site-to-site transport interlocks. (TNG|Brothers) 

Site-to-site transport holds the matter stream in the pattern buffer while the ACB was re-targeted.  Afterwards, the matter stream was redirected to the new location and normal re-materialization was carried out.  

Using this technique, any computer terminal with access to the main transporter sub-systems, or any applicable subroutine, could be used to control transporter operations, including bridge terminals.  This technique could only be utilized when sufficient energy was available to the transporters; all normal transporter limitations would still apply. (Star Trek: Nemesis)

This procedure was particularly useful in emergency medical situations where time is of the essence.  Subjects could be beamed directly to sickbay where treatment could be carried out quickly.  (Star Trek: Insurrection)

Ensign Wesley Crusher used this method in an attempt to outrun those (especially Riker and Worf) who were taken over by the Risa/Ktarian Mind Game. (TNG|The Game)

'''Transporter trace'''

By the 24th century, it was common practice to store a "transporter trace" (a stored copy of a subject's molecular pattern as scanned during a normal transporter cycle).  While it is usually kept for security purposes, in extreme situations the transporter could be modified to use an older trace pattern in place of the latest scan for the purpose of re-configuring the matter stream during molecular conversion, effectively replacing a subject with a younger version of itself during matter re-construction. This technique was first used to restore Captain Jean-Luc Picard after an unsuccessful attempt by an alien energy being to merge with him. (TNG|Lonely Among Us) 

When necessary, a person's DNA could be used to create a transporter trace.  This technique was utilized by Chief Miles O'Brien and Lieutenant Geordi La Forge during a mission to the Darwin Genetic Research Station in 2365. 

The transporter trace itself would be stored for the duration of the person's tour of duty; when that person was reassigned, his or her trace would be deleted.(TNG|Unnatural Selection)

When comparing the transporter ID traces of Deanna Troi, Data and Miles O'Brien before and after they were taken over by Ux-Mal criminals, Doctor Crusher was able to detect that their nervous systems were generating high levels of synapse|synaptic and anionic energy. (TNG|Power Play)

'''Deflecting the transporter beam'''

A transporter beam could be deflected to different coordinates by a tractor beam so that the objects being transported would rematerialize at a point other than the intended target coordinates. Such action could only be detected by examining the transporter log. An unusual amount of antigraviton particles would be present in the emitter coil, as those particles do not occur naturally but are used by tractor beams. Locating the coordinates at which rematerialization took place was not possible; however, it was possible to calculate the point of origin of the tractor beam itself. (TNG|Attached)

'''Single person transport'''

A transporter could be programmed to only allow one particular person to be transported to and from the transporter pad. Thus programmed, no other persons could use the transporter. If the use of the transporter was further prohibited, by use of an unknown access code, using the transporter was almost impossible. 

The only way to circumvent this lock-out was to use the transporter trace from the person who re-programmed the transporter and to input this into the transporter while it was in its testing mode. When in testing mode, a transporter would accept simulated inputs. 

When the main computer could not be used, several tricorders could be networked together to control the transporter. To circumvent the lock-out, access codes from a few bridge officers were necessary to force it in a recall loop. So, everyone who would beam down would be seen by the transporter as the person who re-programmed it in the first place. (TNG|Brothers)

'''Faking a transporter accident'''

A transporter accident could be faked in such a way that a transporter chief would think a person died during transport. For example, this could be done by adjusting the carrier wave of a second transporter to the carrier wave of the first. The person would then beam off the first transporter while the second transporter beamed in a small amount of genetically identical material.

Only a doctor could determine if this material was really the person in question. The transporter trace could be used to compare the logged DNA pattern "trace" to the "dead" person.  Single-bit errors might be detected if the "dead" material was replicator|replicated.

Only transporters that operate on the same subspace frequency as the spoofed transporter can be used for this type of ruse.  For example, some Romulan transporters were capable of this.

Another indicator of such a ruse would be a temporary increase of the matter to energy ratio while transport was in progress.  However, this increase could fall with in the nominal operational parameters of the transporter in question.  Investigation of the transporter logs would be necessary to find evidence of a second transporter signal. (TNG|Data's Day)

'''Emergency mass beaming'''

Some transporters can transport large numbers of people, and either rematerialize them simultaneously, or in groups. However, this is not often done due to safety reasons. In 2268, the crew of the USSEnterprise NCC-1701 used their transporters in this manner to capture members of the crew of a Klingon ship.  In 2377, the USS ''Voyager'' transported over two hundred Klingons off a battle cruiser by expanding the transporter's buffer capacity. (TOS|Day of the Dove; VOY|Prophecy)
