Motion sensor

Is there anyway to re-calibrate or to reset the iphone motion sensor? I think mine is off balance. For example, there is a racing game called "Audi A4". When I am in the game, the car always turns to left if I place my iphone on the table. I have to hold my iphone in a way (left side is higher than the right side) to make the car go straight.

If you are sure the calibration is off, you should consult a mac genius and see if there isn't a defect with your iphone. As far as testing yourself, I suggest you download one of the "leveling apps". Then, level the area you will be placing the iphone on with a "real" level, and test that area with the iphone leveling app. Do you understand where I am coming from? This will be a true test to measure against.

How do I use elvis to record data from a pasco rotary motion sensor

I want to use a pasco rotary motion sensor (a rotary encoder) with ELVIS to record angular velocity. I have a LabPro system which I could also interface. But I was hoping to keep the hardware less complicated by wiring the sensor directly to ELVIS. Does anyone have a sample .vi which would record sensor output?

Hi PCM,
Measuring the time between pulses can be a little complicated. You can have a look at this knowledge base to get an idea of how it can be accomplished. However, since the sensor's output is a stream of digital pulses you can use the counters in this card to get some information from the digital signal. You can use one of the counter’s inputs in the NI-ELVIS and get the frequency or period of the digital signal. One good point to get started is by looking at the counters examples built in LabVIEW, you can find them going to Help > Find Examples > Hardware Input and Output > DAQmx > Counter Measurements. I hope this is helpful.

Hard drive upgrade on 13" MBP sudden motion sensor compatibility

Hello,
I'm planning on upgrading the hard drive in my 13" MBP (aluminium unibody) and I've read a lot of posts regarding the sudden motion sensor conflicts with OS X 10.6.2. I'd like to know if the Western Digital 500GB Scorpio Blue here (http://www.dabs.com/products/western-digital-500gb-scorpio-blue-5400rpm-sata-300 -8mb-58P6.html) would suffer from the conflict (I'm not sure if "Shock Guard" = sudden motion sensor). I don't know if its a simple yes/no or whether its drive / mac specific.
If it would be a problem does anyone have a suggestion for a guaranteed compatible 500Gb hard drive (5400 rpm is fine)?
Any thoughts are much appreciated, thanks for your help!

Western Digital Lists their drive features as:
* IntelliSeek™ - IntelliSeek technology calculates optimum seek speeds to lower power consumption, noise and vibration.
* SecurePark™ - WD's SecurePark technology parks the recording heads off the disk surface during spin up, spin down and when the drive is off. This ensures the recording head never touches the disk surface resulting in improved long term reliability due to less head wear, and improved shock tolerance.
* ShockGuard™ - WD's ShockGuard technology protects the drive mechanics and platter surfaces from shocks during shipping and handling and in daily operation.
* Free-fall Sensor - As an added layer of protection, if the drive (or the system it's in) is dropped while in use, WD's free-fall sensor detects that the drive is falling and, in less than 200 milliseconds, parks the head off the disks to help prevent damage and data loss.
* WhisperDrive™ - WD's exclusive WhisperDrive technology combines state-of-the-art seeking algorithms that result in one of the quietest 2.5-inch drives on the market.
The Free Fall Sensor is the equivalent of the Sudden Motion Sensor. Looking at the specs for the drive you linked to... they list the following features:
Shock Guard, WhisperDrive, SecurePark
As they do not list Free Fall Sensor, I'm guessing this model does not have one so it should not conflict with the internal Sudden Motion Sensor in your MacBook.

10.6.8 update and sudden motion sensor

I have MBP 8,1, 2011 base model i5. Since i updated to 10.6.8 it seems like sudden motion sensor got a lot more sensitive. Never seen it work before, now if i lift the mbp from desk even i can hear the hdd clicking home. I have disabled the sensor and it stops even i move the computer around very fast. So it is not just the drive doing, sensor is triggering that.
I was wondering if anyone knows if sensivity of this sensor changed on last mac os update? or if anyone else noticed it too?
Thx
Ozzy

Hi Ozzy,
I have not noticed any difference on my MBP.
You can try an SMC Reset, which can resolve SMS issues: http://support.apple.com/kb/HT3964

Problem with the Motion Sensor

I just bought my 15" MBP, and was just messing around with it. I downloaded LiquidMac(a program that simulates liquid on your screen and when you tilt your laptop the water flows to that corner of the screen).
And i don't know if my motion sensors are mounted on wrong or what, but when I tilt my MBP to the right the liquid flows up to the other corner. LiquidMac has this option to flip the axis, (so the liquid flows the opposite way) and when I do that then the liquid flows the way I tilt it.
Is this even a problem worth bugging customer support about? Should I consider getting it fixed?
I remember using liquidmac with my old iBook and it would work fine.

Going with a no... your going to bug customer support about a program you downloaded... how is that their problem... if you are going to call anyone about this matter then why wouldn't it be to company you got the program from?

Blackberry z30 motion sensors

Suddenly I have faced a problem with my brand new z30. Motion sensors are not working. After rebooting the phone they work for 2-3 minutes, and somehow go off. I have tried to go back to factory settings – did not help. Have used Blackberry Virtual expert App. It is saying that the phone does not have any sensors then you do sensor tests. I haven’t dropped it or anyway damaged it. I would be extremely grateful for your help. Any thoughts?

C'mon what's happening to nokia.I wish i've never bought this device.I hope nokia will face this issues and realease a GOOD SOFTWARE that can fix this problems.An I hope that NOKIA BELLE could also intoduce in nokia asha 311
this is not smart phone

Where is the Asha line advertised as smartphones? afaik Nokia is clear these are (entry level) featurephones based on S30.
If you would be better of with a different phone why did you not do your homework before you bought the phone?
Nokia Belle will not come to Asha phones. Bell has completely different and much higher hardware requirements.

Is anyone having problems with the iPhone 5 motion sensors?

I having a problem with my phone when it comes to reading movement, the compass doesn't work when it asks to tilt phone to calibrate and in some games it doesn't read when I tilt the phone. I read that apple had a lot of customer complaints about bad motions sensors not be calibrated correctly and I was wondering if anyone else is having/had this problem and what was done to fix it.

I've not had this problem. Thanks for asking.

Second Hard Drive, Sudden Motion Sensor

Back in the fall I put a SSD in my 2007 MacBook Pro. It's working perfectly. I found the "OptiBay" product, which basically replaces your optical drive with an adapter for another hard drive. I haven't received it yet, but when I do I plan on installing it with a traditional hard drive. My question regards the sudden motion sensor (SMS). I disabled it because it's not needed for the SSD, but I was planning on re-enabling it for my secondary that I will be installing. I'm still going to boot off the SSD, though. Is there a way, or terminal code, to assign the SMS to a certain disk? I'm assuming it will just disable the root drive in the event of "sudden motion," but would this affect a secondary drive?
I'd love for there to be an option to change the identifier, from disk0s2 to disk0s3, but I have a feeling it isn't possible or would be infinitely more difficult... thanks.

Most drives are available with the equivalent of an internal SMS. You just have to check the specs. Drive manufacturers often offer two versions of their drives... one with and one without a SMS. If you get a drive with the SMS built in, you can just leave the MacBook's internal one disabled.
Here is an example of one of the most popular drives:
http://www.seagate.com/www/en-us/products/laptops/momentus/momentus5400.6g/
Seagate's SMS technology is referred to as G-Force. Note the product number: 5400.6_g. The "g" denotes the drive has a "G-Force" sensor.

Motion Sensor not working in 10.3.9

I just noticed that my sudden motion sensor (SMS) isn't working. All other topics seem to be about problems on 10.4, but I'm on 10.3.9. The System Profiler shows the SMS to be active, but I tried two freeware apps and niether works. I've had my motherboard replaced in the recent recall as well as the topcase for the sudden sleep problem. Could that be linked? I tried running the Apple Hardware test and it came up clean.

I did find that article when researching the problem, but my profiler already says the SMS is active so it should be working. I wonder if disabling it, then re-enabling it would do anything.
Can't help but wonder if the motherboard replacement has anything to do with this. Or if another odd thing is related. AppleCare insisted, so I did an archive and install when trying to solve my NAP (Narcoleptic Aluminum Powerbook) and soon found my Software Udate wouldn't work from the Finder menu selection (I am able to get the update to run from the System Preferences panel).
Don't know if that helps, but, any ideas?

HT1935 In sudden motion sensor terminal it will not let put in my password...can any one help me?

While recording music was prompt...
Disk is too slow or System Overload.
(-10008)
The Sudden Motion Sensor may have parked the hard drive head, or the disk performance is not sufficient to read or write all audio tracks, or the system was not able to process all data in time
hard drive to slow...
followed direction but it would not let me enter password. No keys will work on keypad when trying

It's normal to see no characters on screen when entering the password for sudo - they're still recognised.
As Apple say at http://support.apple.com/kb/ht4103
When typing the user's password after the "Password:" prompt appears, you will not see anything appear in the Terminal window. Just type in the password and press Return. If the password is entered incorrectly, you will see the message "Sorry, try again" and be given another chance to enter the password correctly.

Apps that use motion sensor?

Are there any apps available now that take advantage of the new motion sensor in the 5S? Thanks?

If you mean custom AS3 classes, yes you can use those. What you can't do is create an ANE that calls into the private frameworks of iOS itself.

Why would I get a Sudden Motion Sensor error on a Mac Pro (not a laptop)??

Get this error all the time since upgrading to Logic 9.1.4. Thing is, I have a Mac Pro, not a laptop.
Apple sends me to this page:
http://support.apple.com/kb/HT1934
Should I disable sudden motion sensor? Seems silly. I am recording woth headphones, there's no movement from the computer. And again, didn't have this error for 3 years and suddenly I get it after upgrading to 9.1.4?

9.1.4 seems a bit shaky...
That said, you might try disabling "Sleep" for the drive.
As I recall, it's a generic error meaning the computer either isn't getting a response from the drive or that it can't pull data off fast enough.

Sudden Motion Sensor not working after upgrade to WD5000BEKT HDD

Hi everyone, I just upgraded the hard drive on my Macbook Pro (2010) and I am very pleased with the performance of this 7200rpm drive, I have seen reads around 105MB/s and a pretty good boot time at 23s. But I used to be able to hear the hard drive stop when I moved the computer around before due to the Sudden Motion Sensor technology and since I have the new hard drive in it doesn't seem to work anymore. I have tried switching SMS off and on and it didn't change anything, also the drive is a Western Digital Scorpio Black without Free Fall sensor (I took that version on purpose so it wouldn't conflict with the SMS). Do you have any ideas on how to make it work again? Because I really like this feature on my Mac (I have dropped a laptop before so just in case it happens again). Thanks a lot for your help.
Scott

For future reference, here are a couple of kb articles on the sudden motion sensor:
http://support.apple.com/kb/HT1935
http://support.apple.com/kb/HT1934
As has been said, Apple's Sudden Motion Sensor is not actually built into the hard drive. In fact, some hard drives with their own version of a sudden motion sensor like Seagate's G-Force Protection actually will set up a conflict with Apple's Sudden Motion Sensor.
I installed the same WD in my Mac as you did, and I hope you enjoy it as much as I have been enjoying mine.

Sudden Motion Sensor on OSX 10.4.6 (iBook/PowerBook G4)

cheers!
according to http://docs.info.apple.com/article.html?artnum=303178, there is a problem with the sudden motion sensor on my ibook g4 14'.
my questions are:
1. is the sms really not working or is it just not showing up in the system profiler?
2. what should i do to bring sms (back?)to work? install a macosx-version prior to 10.4.3?
3. did the sms on my ibook ever work? bought it with 10.4.3 on it.
thanks for the answers.

Hi Mmkay,
Welcome to Apple Discussions
I am sorry, but just to make sure; Does the Sudden Motion Sensor not show up in System Profile (Getting Information About Your Computer (System Profiler)). In System Profiler > click on the Hardware tab > Look in the main window and you should seen Sudden Motion Sensor below Serial Number. Does it say State: Enabled? If it doesn't show up, bring it to your local Apple Store. I don't think that reinstalling the system software will make a difference.

Where is Sudden Motion Sensor data stored?

Background:
I replaced my superdrive with an optibay + ssd (OS is stored here) and I left the stock HD (home folder) in it's place.
Problem:
I guess I triggered the SMS the other day and now I can't access my HD (basically just hangs / takes forever to load anything) unless I disable SMS. Where would I clear the data / tell it that my HD is safe to use again. Restarted pram and reinstalled OS, but it didn't help.

Thanks for the responses. Yes, as JoeyR stated, I replaced my superdrive with an SSD and the hard drive is in it's original place so I wanted to re-enable the sudden motion sensor. Thank you for clarifying how the SMS works. I wasn't sure if there was a state that was saved somewhere.
Well the original issue was that my OS would boot (SSD), but I couldn't get into my login (HD). I have a temporary user on the SSD so I was able to use that to troubleshoot. I swapped my HD with another one and it worked (STOCK HD). Then I tried putting the HD into an external closure and that worked as well. I had a feeling it was the connector, but I did not have spare parts to test this theory. I would swap the HDs back and forth and sometimes it would work and sometimes it wouldn't. It was a hit or miss situation. It worked when I disabled the SMS, but when I enabled / disabled it again it didn't work. Ran diagnostics on the HDs, both drives seem fine and in perfect condition. Tried to format the hard drivers and do various combinations of swapping drives and in the end the problem still persisted so it had to be a connector issue. I brought it into repair and they replaced the SATA cable for me and all is good now.
Thanks for the help.
