Yeah, when my $1000 phone acts up, I just flush it down the toilet. The part that amazes me, is how quickly the helium seems to incapacitate the phone. It's like there's no seal at all around these things. They could have designed a free-wheeling backup oscillator to take over from the MEMS when it takes a snooze. It didn't have to fail that way. They could also gate off the free-wheeling oscillator until it's needed. Paul |

That is just silly. To change the velocity of sound (which is what the chipmunk voice is due to) requires a substantial fraction of the air be Helium. In that case the problem would not have been Apple watches, the problem would have been that everyone was passed out on the floor. because there was not enough oxygen. Remember there was venting some of which leaked into the hospital. Ie only a fraction of that 120 liters ended up in the atmosphere of the hospital. And hopitals are typically very big buildings. Ie, the fraction of He in the air was almost certainly at most a few percent. Again, it is hard to see how that would have altered the frequency of the mems by much. Maybe they are so sensitive to frequency changes. Note that sticking a phone/watch into a bag and putting in He, would have been a concentration of 50-100 % which is hardly the equivalent of the hospital. This story sounds to me like and urban legend that has escaped from its zoo. |

They could also gate off the free-wheeling oscillator until it's needed. The clock is ALWAYS needed. And the backup oscillator would have completely destroyed the value of the mems oscilaltor int ehfirst place (its value is size. It is like riding a moped and asking why your do not have a Mac Truck as a backup if the moped fails) Paul |

Read the fine article. Otherwise you are ignorant and even worse, sound as though you are ignorant. Let us stop feeding a cross posting troll. bliss -- bliss dash SF 4 ever at dslextreme dot com |

It would take android devices to have MEMS resonators instead of crystal oscillators for them to be affected in the same way, but plenty of non iThings have MEMS devices in one form or another. I'm not clear why an oscillator would be "open" to the atmosphere, whereas a barometer would need to be. |

They were sealed, and most likely contained either a vacuum or a specific gas. However, helium diffuses through everything at an astounding rate, and something about these particular parts made them especially susceptible to small amounts of helium. It probably changed the velocity of sound inside the device just enough to screw it up. Other brands of oscillator might also have been affected but if they merely shifted off frequency a bit no one would have noticed. It's also possible that these oscillators didn't stop either, but shifted frequency enough to cause the operating system to become alarmed and/or confused. -- John Hasler Dancing Horse Hill Elmwood, WI USA |

I wonder how many Apple people have followed their bad oscillator apps off a cliff so far? This brings up an idea for a new hack. Get in front of a self driving car and open up a helium bottle. |
