The term used here, "trident scanner," comes solely from the script for "Trials and Tribble-ations," where the device is apparently named after its general shape, which resembles a trident.
Shouldn't it be in one of the "Unnamed technology" pages then? --LauraCC (talk) 18:48, October 13, 2015 (UTC)
No. In those cases, where something is identified like that, we're happy with separate pages for them as per MA:RESOURCE, specifically the "In-universe resources" section. -- sulfur (talk) 18:50, October 13, 2015 (UTC)
