Originally explained to be Data Boxes containing vital information about The Burn, the devices are made up of a small box and an earpiece transmitter allowing communication with Charlie and, later, Soleil.

They were originally developed as an implant to help in the treatment of Malaria C because of their ability to help stimulate the production of brain cells. They were then incorporated into Project Sevendays as a way of linking a human brain with the developing AIs and later, as a failsafe allowing the AIs to be destroyed.

Upon realising Soleil's ambitions, Charlie sent for the devices to be brought to the hard access point in Edinburgh which would allow Charlie and Ivan to destroy Soleil.
