This IT Professional forum is specific to the Office version. My client purchased a retail box version of Office back when it was the most current product. (United States) to be presented with the message "Telephone activation is no . what you do is make a text file with the following code in it.

One recovered after a week, the other never did. According the the field service engineer who de-installs magnets for a living, this is a common problem. He attributed the problem to EMF noise caused by bleeding off current from the coils. That theory seems more probable than a low level He leak, but neither one seems likely. I wonder if I could get a grant from Apple?

  5. Or so you'd think.

The critical concept is that helium is free to move across the seal that blocks other gas, so over time the concentration of helium inside and outside the package will balance. There is normally very little helium in air, so releases of gas into a room will drive the concentration up by orders of magnitude even though the total percentage of the gas is still relatively low.

That higher concentration diffuses into the MEMS package. MEMS oscillators require a vacuum to operate properly https: Likely there is a small frequency shift with degraded vacuum, enough to disrupt the timing of the electronics that depend on stable clock frequencies. As for recovery, elevated temperature will help speed diffusion of helium back out of the package once the phone is in a normal atmosphere. I wonder if the Apple store is going to have a air chamber to bring back all the dead phones. Those commenting that the photo shows a CT machine are correct. You are getting confused by oscillators used in time-of-day clocks — like a wristwatch or a wall clock.

Those oscillators typically run at 32kHz. No CPU oscillator runs that slow. I work in an Magnetoencephalography lab MEG for short and over here we also use liquid helium to cool down our device. Apple watches were series 1 and 3 and the apple iPhones were all the iPhone 8. It does seem to only effect these particular generations of devices: Series 1 and up for apple watches and iPhone 6 up does not effect iPhone 6. Anything before these generations, and nothing happens to these older devices.

Our lab has been pondering this mystery for the past 8 months and while we suspected it was the Helium we had no definitive way of confirming what was happening mechanically. So can MacGyver use a helium balloon to stop a ticking bomb with 1 second left on the clock? I think we all know the answer now. Venting L of Helium indoors is very dangerous. There should be an NCR on this event. Things should be remedied so it never happens again. The For skeptical Sam, GE and Apple have both acknowledged that helium leakage was the issue.

GE is aware of this case. Only the currents generated are like times stronger. Apple products suffer massive wireless charging overload even if the distance is like 5 meters from ramping power supply…. I was of course blamed, as a matter of course goes with the territory. I dismissed the matter as one of those things…. I can second that. Changing flux fields and gauss fields will interfere with the iPhones inductive charging. Many cases have been observed with the range of up to 30 meters away from the ramping.

Most phones come back eventually after a long time of charging, but some never come back. Concerning what Yoda, Tyler V. Jones write, I agree that it is unlikely, that the main clock of the system is a But if the oscillator is only used for the RTC, why does the phone totally depend on it working exactly?

The comments about Hz oscillators not being used for system clocks I. High frequency crystals are often avoided to reduce radiated EMI. Both to meet regulatory requirements and to reduce the noise floor for any radio receivers located on the same board. Low speed clocks are sometimes used directly for CPUs in low power operation.

Even when a CPU is in a high frequency clock domain derived from another source it oftrn needs to wait for a peripheral that may be in a low frequency clock domain that may be derived from a Hz oscillator. If the peripherals clock stops completely then it may lock the CPU. So a great deal more than real time keeping can be affected. Thanks a lot, now we are getting somewhere.

Apple - USE TAG

Not that I want to deny what you are saying, but how exactly is this advantageous? As I understand it, you still have the high frequency somewhere, you still need to spreed it all over the core of the CPU, because every latch or thingy there needs to know at what exact state the rest of the system is, in order to work in sync with it. That is, calling this an OS bug, if it is so.

Seriously, a total system lockdown if some data form some sensor does not arrive as expected? Try it with hydrogen. Be sure to use eye protection. I used to use Helium to do vacuum leak tests and on a couple of occasions found leaks due to Crystalline imperfectsions in the stainless steal tubing caused by poor manufacturering. You can also control the slew rate to limit harmonics. A crystal requires a certain amount of drive current that current needs flow through a PCB trace.

So there can and usually will be lots of radiated EMI at undesirable frequencies. Pretty much any high speed signal say to the RAM on a PCB is going to have some form of series termination to limit slew rates and harmonics as well as ringing in devices like these. You can get MEMS oscillators with the PLL built in but the idea is that output is low voltage, low drive current and has a low slew rates to limit emissions.

As to Android phones. Apple will be using them because they are tiny. Most Android phones are probably still using standard Hz tuning fork type crystals to do the same job. At the low Hz frequency and with the tiny drive currents these crystals require any EMI they radiate is typically a non-issue. Im constantly crawling around the machines with the phone in my pocket, or using it to take close up pics of things.

All while the magnet is on, or ramped up. Great phone. So they also need liquid helium to cool the superconducting magnet. The LHe boils off and contaminate the air around. We found out that very small amounts of gases is enough to shut down iPhone 8 and X for one to three days.

Older models like iPhone 6s and 7 do not shut down but have serious problems for a day or so with mobile network connections. Wifi is fine. Model 6 and older does not get affected due to our experience. I hope Apple will fix this problem with the next generation. Excellent article! My boss had the exact same problem. His iPhone 8 failed, was repaired then the replacement failed during a helium fill of our nuclear magnetic resonance spectrometers… He got the cash back for the 0hine and bought an iPhone 6!

Working in inert atmosphere gloveboxes, it is well know that dry helium and argon knocks down static to zero while dry nitrogen atmospheres have static problems. Low levels of helium can alter charging in gas phase reactors as well. We never looked into why but suspected helium ionizes readily and facilitates movement of charge to neutralize static. If the micro devices have significant potential differences, perhaps helium is interfering.

Thank you for this article. This describes our problem exactly.

We have a SQUID-based device that gets filled with liquid helium every week leading to slightly higher than normal concentration of helium in our building. For over one year, ever since I upgrade to the iPhone 7, I have been complaining to Apple that my phone was having problems after spending time in my building. At the same time a co-worker upgraded to an iPhone 8 and her phone would discharge after being in the building after some time.

  • For months I was frustrated that I was not being able to use my phone except after being away from work for over 24 hours. I conducted a series of experiments to reproducibly confirm that the source of the problem was being inside my building. Also I knew that no other brands of phones and iPhones versions 6 and older were not affected. I continued to insist that the problem was their phone my iPhone 5 had worked totally fine for years and that giving me another was not going to fix the problem.

    I tried to escalate the matter at Apple and their final solution was for me to purchase a upgraded phone. I am still frustrated since I cannot bring my phone to work! This causes a liability problem for our Hospital. We have been troubleshooting with Apple engineers for several months with no solution until now. I hope that Apple takes notice and fixes this problem. It sounds like Apple knew about this issue and they have not taken the proper steps to notify their consumers, nor properly train their own staff to resolve these issues. These phones are expensive!

    Cellular service is expensive! Apple consumers should expect these products to work. I am curious to see how Apple will handle this. As a side note, we have noticed that FitBits do not work in our building as well after long exposures. I am wondering if its a similar problem. The 50 micron on the bottom right is just as scale. There are some technological error statements in the text and on the pictures captions. The clock frequency inside a regular iPhone or Android device is waaaaay over the 32kHz stated in the text, the Iphone processors run over 2GHz, while Android runs around half of that and it is frequency adjustable by the processing necessity.

    Also, without external gas pressure being greater than the internal pressure of the chips, gases will have a very long hard time to enter the chips. This may happen if the chips cools down rapidly reducing inner pressure, sucking some gaseous around the chip. As usual, when a text starts to present different and several flaws, it looses technical credibility. I suppose the pressure is plausible. Helium is used for leak detection because it is an atomic vs hydrogen which is molecular here on Earth so it has a smaller diameter than every other atom or molecule.

    I imagine that the device is sealed for atmosphere with is primarily molecular nitrogen and molecular hydrogen. Helium could have migrated in and increased the pressure but highly unlikely because the helium goes up even in turbulence. Posted 1 day ago — By Lucas Coll.

    New iPhone 11 release date, price, news and leaks

    Wireless inductive charging has been one of the longest standing iPhone rumors that hasn't yet panned out, and KGI Securities analyst Ming-Chi Kuo who has a solid track record for Apple predictions believes all of Apple's new iPhones will include the feature this year. In June, the sleuths at MacRumors discovered a new sound file , buried in iOS 11, that they believed would be the sound an iPhone would make when it was placed on an inductive charger.

    The battery widget will use a different icon for the new iPhone, this suggests a different charging mechanism pic. One of the most intriguing rumors surrounding the new iPhone is that there will actually be three new phones this September: The "S" series phones, like before, would adopt the same design as today's iPhones, only with a little more muscle and some other likely upgrades under the hood.

    Today, that theory seems likelier than ever before, because of two final discoveries.
