Probably one of those heart/pulse/blood pressure monitoring devices, with a
motorized belt that slides across the platform, and enables you to run, while
you're 'wired for sound' (being monitored for health & safety reasons).
The RFI started back longer ago than that, though. Old(er) TVs, when they had
tuners that weren't on an IC, had a single, non-sheilded wire from the tuner to
the circitry. No sheilding for RFI, whatsoever.
John/WA5BXO could tell a lot of stories, being that he must have worked on at
LEAST a Grizzilion TV's over the years, there at Delta Plaza, TV (Home Of The
Happy New Year, All!

May your moccasins make happy tracks In many snows
and May the Rainbow Always touch your Shoulder
