Emergency Engineering Hologram
The Emergency Engineering Hologram (EEH) was a sophisticated hologram that was designed for use as an emergency engineer during the late 24th century. 

By late century, EEH programs, as well as variations on the "emergency" theme, were all incorporated into the customizable Emergency Hologram basic installation. Such packages were available on board Kaplan F17 Speed Freighters. ()
