Behind the scenes
On the back the device is identified as "FLUX SENSOR CM-88B 180924609". This is a rather obscure reference to the movie Alien, specifically the central vessel the movie takes place on, the USCSS Nostromo - the CM-88B refers to the ship's model; the 180924609 refers to the ship's registration number.
