Tachyon inhibitor
From Tardis Wiki, the free Doctor Who reference
A tachyon inhibitor was a piece of temporal hardware that protected its wearer from cause and effect which resembled a bracelet. Rose Tyler found and put on a tachyon inhibitor on board the Lect spaceship. Rose was blasted into the Time Vortex when the Unon attacked the ship, but she was protected from the time winds by the tachyon inhibitor until she was sucked into the time scoops of Glom's ship. The inhibitor overheated and burnt out from it protecting Rose. (COMIC: Weapons of Past Destruction)
