A universal translator produced for Star Trek: Enterprise and seen in Season 4, Episode 20 'Demons' and Season 4, Episode 21 'Terra Prime'.
This item is the universal translator that Hoshi Sato (Linda Park) was trying to repair in the episode, 'Terra Prime'. It has a pair of graphical applications representing Starfleet inventory numbers on the back where a Velcro strip to attach to clothing normally would be.
