• Integrate the acceleration to get speed using time domain mathematical

  I'm trying to do something simple, but have not found the answer to my problem.

  I have a loop that couple as input and calculates the acceleration; See attachment.

  I'm trying to calculate speed using acceleration.

  I used the function of continuous integration of time mathematical field, acceleration plugged as a signal, but the speed that it displays is not correct.

  If the acceleration is 1 / s ^ 2, the calculated speed is tens of thousands in / s in the second. This is not true.

  What I am doing wrong?

  Thank you

  Looks like I posted this in the wrong place. Don't know how to delete it well.

• Error-200431 occurred at .vi DAQmx Create Channel (I-acceleration-accelerometer)

  Hello

  I tried to use DAQmx Create Channel to accelerometer and yet it responds with error (see below). When I use max OR to measure the accelerometer (I-acceleration-accelerometer), there is no error, and I see that acceloremeter works.

  OR PXI-1042 and I use OR-4462 card to measure vibration vith acceloremeter.
  

  Error-200431 occurred at DAQmx Virtual Channel Create

  Possible reasons:

  Physical channel selected does not support the type of measure required by the virtual channel you create.

  Create a channel to a type of measure that is supported by the physical channel, or select a physical channel that supports the type of measure.

  Property: I. MeasType
  Requested value:
  You can select: sound pressure, voltage: Microphone, accelerometer, Position: Eddy Current proximity probe, Force sensor: IEPE, speed sensor: IEPE

  Hi serdaryilmaz,

  I'm not sure why the accelerometer mode does not work, but it works very well in normal mode - it maybe has to do with the accelerometer, you?  Whatever it is, if it works with the voltage mode, I am happy that we found a way to make it work.  Is this an acceptable work around you?

• How do you derive speed and acceleration data position?

  Hello

  We are working on a project that requires data of distance, speed and acceleration over time.  We use the NI 9234 compactDAQ chassis connected to an accelerometer.  The accelerometer is attached to a topic plastic cantilevered (rectangular) which is "gathered" - a bit like a ruler on the edge of a table hanging like a diving board.  We will gain about 2 k samples/sec.  There is no problem getting the acceleration data, it is transformed in speed and distance, which is the problem.  There is a link OR a solution (http://decibel.ni.com/content/docs/DOC-4308, see below), but it does not work.  I remember in my class of calculation that you integrate acceleration to get the speed, you integrate the speed to get remotely.

  

  This gives us the following graphs:

  

  Acceleration seems good, of course.  But the speed looks like it is a sinusoidal signal riding on a curve that dips down and then decreases exponentially.  (This dip and decomposition looks like the answer to an excessive vibration.)  I expected to be similar to the acceleration, speed, but out of phase 90 degrees (symmetrical relative to the origin).

  And we want the position and not remotely.  Position would also be a sine wave exponentially decaying.

  So, what math should apply?

  Thanks in advance,

  Shadowfeld

  Hello

  Conversion acceleration in the speed/movement or movement speed requires the digital integration. In LabVIEW, you can take the accelerometer measures and represent this signal in acceleration, speed or movement by running the example VI (Figure 1) included in the next tutorial for area Developer:

• problem in using the accelerometer in my game

  Hi, I am new to AS3 and I create a game for android using the accelerometer.

  

  the game:

  the player needs to collect coins and throw bombs by moving left right.

  code:

  I took the code frome the extracts of 'code' that offer Flash and make a little change.

  var fl_Accelerometer:Accelerometer = new Accelerometer();

  fl_Accelerometer.addEventListener (AccelerometerEvent.UPDATE, fl_AccelerometerUpdateHandler);

  function fl_AccelerometerUpdateHandler(event:AccelerometerEvent):void

  {

  itamar_a.x = event.accelerationX * 130;

  }

  the problem:

  When the player loses and he gose back to start the game - the speed of the drive has become higher and higher.

  After some tests, I can't control the player because of the very high speed.

  I hope I was clear... Please help!

  Try:

  If (itamar_a.hitTestObject (bomb)) {}

  fl_Accelerometer.removeEventListener (AccelerometerEvent.UPDATE, fl_AccelerometerUpdateHandler);

  gotoAndStop (3);

  itmar_a.y = 1500;

  }

  Hi iambjan,

  I understand that your MacBook Pro has been lost by the intermediary of find my Mac mode. Fortunately, you can go to the off mode lost through the steps described below.
  

  You can disable the lost Mode by entering the password of the device, or by following the steps below. Alternatively, you can follow the steps below to change the details displayed on your lost device.

  Note: If your credit cards and debit to pay Apple have been suspended because you put your iPhone in lost Mode, when you disable lost Mode and reconnect to iCloud, you can continue using your cards.

  1. Go to find my iPhone on iCloud.com.

     If you don't find my iPhone on iCloud.com, your account has fair access to the web features only iCloud. To access find my iPhone and other iCloud features, set up on your device iOS or Mac iCloud.

  2. Click on all devices, and then select the device that is lost.

  3. Click on lost Mode, then change the information or lost the stop Mode.

  If you cannot use lost fashion as find my iPhone is not configured on your lost device, see the article by Apple Support If your iPhone, iPad or iPod touch is lost or stolen.

• an iPhone 5s cable charger can be used on an iPhone 4S

  I used a my iPhone 4S cable charger on someone of another iPhone 5s.  Now my charger cable does not work.  It's probably too bad?  Stores are closed tomorrow because it's a day holiday here and my phone is low in the battery.

  IPhone 5 s charger cable allows charge and iPhone 4S?

  When the shops are open on Tuesday I go to solve the problem.

  Jake

  Your original question answered on the use of the iPhone cable.  iPhone 4S cable charger can be used on an iPhone 5 s  IPhone 5 s is a lightning cable, and iPhone 4S uses a 30 connector pins. To use for each other, an adapter must be used. While it would be rather strange that he stop work could lead to the use of the cable with other devices, everything is possible. You can make an appointment on the Apple Store to have the cable looked at, and if it is under 1 year and found damaged and not corrupted user, Apple should replace it.
