The Pulsator was an apparatus that, upon connection to a starship, generated a weak electrosynaptic signal.
Following extensive study of Assembler biology, Boba Fett discovered that Assembler organic material was capable of being revived with a pulsator. He then resurrected Kud'ar Mub'at along with his levitating web around 4 ABY. Fett utilized the Hound's Tooth for power and concurrent data transmission, and he inserted the pulsator's tip (a metallic needle) into a nexus of nerve clusters located within the Assembler's cranium, thus bringing the deceased body back to life.
