How a Helium Leak Disabled Every iPhone In a Medical Facility (vice.com)
dmoberhaus writes: In one of the strangest system admin tales of all time, one IT guy details how a new MRI machine managed to disable every single iPhone, Apple watch and iPad in a medical facility while leaving the rest of the devices untouched. Eric Woolridge, a system administrator at Morris Hospital in Illinois, said in a detailed post on the r/sysadmin subreddit that helium was to blame for the malfunctioning iPhones. "[T]he MRI installation involves supercooling the giant magnet in the machine by boiling off liquid helium," reports Motherboard. "This evaporated helium is usually pumped out of the facility through a vent, but this vent was leaking the helium into the rest of the facility. In all, about 120 liters of helium (or about 90,000 cubic meters in its gaseous state) was pumped out of the MRI room and an untold amount leaked into the rest of the hospital."
In a blog post, iFixit notes that helium atoms can wreak havoc on MEMS silicon chips. "MEMS are microelectromechanical systems that are used for gyroscopes and accelerometers in phones, and helium atoms are small enough to mess up the way these systems function," reports Motherboard. What's odd is that Android phones were not affected. Apparently, the reason "is because Apple recently defected from traditional quartz-based clocks in its phones in favor of clocks that are also made of MEMS silicon," reports Motherboard. "Given that clocks are the most critical device in any computer and are necessary to make the CPU function, their disruption with helium atoms is enough to crash the device."

Obviously the helium concentration wasn't very high -- people could breathe and talk without sounding like Alvin the Chipmunk. I wonder if this can be exploited to mess with iPhone-owning hipsters at a party -- a balloon inflator sized helium tank and the appropriate valve orifice should do it...
OMG! My phone just died! *head explodes*
Helium detector.
Slashdot, fix the reply notifications... You won't get away with it...
MEMS oscillators are significantly more reliable than quartz oscillators.
Until someone spills the helium, that is...
Browsing at +1 - no ACs, I ignore their posts. So refreshing!
They really should have sensors to detect these conditions in places where large amounts of gas is used.
They did. iPhones.

With all the hot air that comes out of your lying mouth im surprises your icrap still works.
It doesn't seem that hard to recapture the helium. Just put the fill nozzle to a blimp at the vent. Once the blimp is filled up, fly it to the helium recovery plant where they will liquify it again and reuse it.
