Brains has developed a Personal Transmitter, that when swallowed can be used in emergency when anyone's captured and can't contact base. A new smaller version has been designed, which is flavoured to help with swallowing. Tracy Villa is equipped with a hidden monitor screen (behind the portrait of Alan), that tracks the transmitter once it has been swallowed. Brains has also invented a Transmitter Dissolver, that can be taken like a medicine, to remove the device once it is no longer needed.
