Engineering technology

Flow regulator

• Component of high energy power plants allowing regulation of output energy to varying specifications (SCE Short Story: "Foundations, Book One")
  • Overtaxing output can result in damaging flow regulator, causing full-strength output and risking overloading or destroying connected systems (SCE Short Story: "Foundations, Book One")

Construction equipment

Extractor

• Industrial pump used to remove large quantities of fluid (either liquid or gaseous) from an area (SCE Short Story: "Wildfire, Book 2")

Laser drill

• Laser-based drilling technology commonly used in constructing underground chambers and networks for asteroid or planetside bases (SCE Short Story: "Foundations, Book One"; TNG: "Home Soil")
• Mark III implementation developed by 2265 (SCE Short Story: "Foundations, Book One")

Mobile drilling rig

• Mobile phaser-drill platform used in mining operations (SCE Short Story: "Foundations, Book One")
• Maneuvers via antigravity units coupled with stabilizing thrusters (SCE Short Story: "Foundations, Book One")
• Automated drilling implements at fore of vehicle disintegrate rock strata through multiple emitters, permitting steady operation without risk of overload (SCE Short Story: "Foundations, Book One")

Plasma drill

• Plasma-based drilling technology used for areas with especially dense strata (DIS Novel: Desperate Hours)
  • More powerful alternative to laser drills

Handheld tools

EPS pattern tracer

• Engineering tool (DS9 Novel: Mission Gamma: Cathedral)
• Presumably used to detect faults in EPS conduits

Magnetic probe

• Used to directly manipulate magnetic field configuration (TOS: "That Which Survives"; SCE Short Story: "Enigma Ship")
  • Commonly used to manipulate antimatter containment fields for maintenance purposes without shutting down containment (SCE Short Story: "Enigma Ship")
• Phased out c.2300 (SCE Short Story: "Enigma Ship")
  • Presumably due to finer control over magnetic field configuration rendering it unnecessary, coupled with risk involved in directly manipulating such fields

P-38

• Emits a broad range of sound and light frequencies in order to open wedged panels (SCE Short Story: "Interphase, Part Two")
• Also produces magnetic field emissions to counteract magnetic seals, often allowing for opening of sealed doors or compartments (TNG Novel: Available Light)
• In use by mid-23rd century (TOS: "The Trouble with Tribbles")
  • Per annotations of "Many Splendors"

Power plants

PXK fission reactor

• Still in use by mid-23rd century (SCE Short Story: "Foundations, Book 1")
