The communicator is a fictional device used for voice communication in the fictional universe of Star Trek. As seen in at least two instances, the Original Series episodes "Tomorrow Is Yesterday" and "Day of the Dove," it can also serve as an emergency signaling device/beacon, similar to a transponder. The communicator allows direct contact between individuals or via a ship's communication system.

Wah Ming Chang was an American designer, sculptor, and artist. With the encouragement of his adoptive father, James Blanding Sloan, he began exhibiting his prints and watercolors at the age of seven to highly favorable reviews.
