The activation device enables the snowmelt system to run 100% automated.

She cast around for any sort of recognizable control pad or activation device, but all she could see were the same uneven facets twinkling in the light of her helmet lamp.

He then applied this discovery to the ear and designed the Synchrophone which later became the alternophone, a cerebral activation device and wrote "Activating the brain with alternative hearing".

He planted secret activation devices in almost every system on the ship.
