Isolinear co-processor
An isolinear co-processor was an important component in Deep Space 9's security systems, designed to detect weapons on the station's Promenade.

In 2369, Neela collaborated with Vedek Winn Adami to assassinate Bareil Antos on Deep Space 9 as he was considered most likely to become the next kai. Neela covertly placed a subspace relay in an isolinear co-processor in Odo's office, so it would seem on the security sensors that there were no weapons on the Promenade and Neela could kill Bareil undetected. Fortunately, Miles O'Brien discovered Neela's tampering and Benjamin Sisko was able to subdue her. ()
