I'm the author of the articles and did just now see the comments here. The brush contains a NFC tag and will open phillips.com once you hold it against your phone's NFC reader. That is the payload that comes back from this call.
You got a very noisy signal without much information (the gray thing in the background) with an random map overlay generated by wxtoimg. Try to hide the map overlay and you should see the picture you really received.
I already received aircraft positions (ADS-B), aircraft radio, ACARS, VDL, HFDL, satellite pictures, ISS pictures, a ISS astronaut speaking, a bunch of other satellites (including radio pirates on US military sats), small outdoor weather stations, a portable radio for children, some AM radio stations, a lot of ham radio and pagers.
There is also huge amount of signals I can't decode yet.
