• Calibrate the accelerometer and orientation sensor

  Is it possible to calibrate the accelerometer and orientation sensor? For my motorcycle G sensors are not accurate? I think there is a way to edit some system 4.4.4 android files.

• What is the range of temperature for the 9219 and 9211 measurement modules using a K type thermocouple as the sensor?

  Hello

  hope I posted in the right place. I'm about ready to buy a cDAQ-9172 chassis and modules temperature 9211 or 9219 universal. I have not yet taken my mind yet. Then, I thought that one of them would make the temperature range required that I need. I need to go from-40 ° C to + 200 ° C and I will use a K type thermocouple. Does anyone know what are these upper and lower limits with this configuration?

  Thank you

• Mulitasking on Casacde (Backbround thread for reading the accelerometer and in the foreground UI update)

  Hello

  I make application to read data from the accelerometer. I create the user interface using C++ and when the user clicks on the application startup button taking users accelerometer reading. I tried to update x, position y of the component and textarea or a text label. How can I do?

  I've attached my app.cpp file in which I want to update the text of button or label and move the image to different x, the coordinate y.

  I'm multitasking successfully implemented over the waterfall.

  Here is my code in which the two wire work in parallel.

  Step 1: Extend the class with the Thread class

  Step 2: The signal whenever you want to update your UI Thread class

  Step 3:

  QObject::connect (myThread, SIGNAL (signalGUI (float, float, float)),)
  SLOT (showUpdatedData (float, float, float)));

  myThread is an object of the class as we thread createad by exteding the Qthread.

  signalGUI is a signal that emerging us from the worker thread.

  showUpdatedData is a slot in which we write the code to update the GUI.

  In this way we can implement multitasking on the waterfall.

  Planning your Partitions

  The Question

  Partitions, how much should I have on my hard drive, what do I use
  each of them for, and what size should each one be?

  It s a common question, but unfortunately this doesn t have a
  only simple, just answer to all the world. A lot of people will respond with
  the way they do, but their response isn't necessarily best for the
  person seeking (in many cases it isn't right even for the person)
  response).

  Terminology

  First, let's rethinking the terminology. Some people ask "should I".
  partition my drive? That s the wrong question, because the
  the terminology is a little strange. Some people think that the word
  "partition" means divide the drive into two or more partitions.
  That s not correct: to partition a drive is to create one or several
  partitions on it. You must have at least one partition to use
  He who think they have an unpartitioned disk actually
  have a player with only one partition on it and it s normally
  Called C:. The choice you have is to have more than one
  partition, not that it's the partition at all.

  A bit of history

  Back before Windows 95 OEM Service Release 2 (also known as Windows
  95 (b) was published in 1996, all MS-DOS and Windows hard drives have been set
  using the file system FAT16 (except for very tiny to aid
  FAT12). That 16-bit only because were used for addressing, FAT16 has a
  maximum 2 GB partition size.

  More than 2 GB of hard disks were rare at the time, but if you had
  one, you must have multiple partitions to use all the available
  space. But even if your drive was not larger than 2GB, FAT16 created
  Another serious problem for many people - the size of the cluster has been
  more great if you had a larger partition. Cluster sizes increased from 512
  bytes for a partition to no greater than32Mb all the way up to 32 KB for a
  partition of 1 GB or more.

  More the cluster size, the space more is wasted on a hard drive.
  That s as space for all the files is allocated in whole clusters
  only. If you have 32 KB clusters, a 1 byte file takes 32 KB, a file, a
  greater than 32 k byte takes 64 k and so on. On average, each file
  about half of his last group waste.

  If large partitions create a lot of waste (called "soft"). With a 2 GB
  FAT16 drive in a single cluster, if you have 10,000 files, each
  lose half a cluster of 32 KB, you lose about 160 MB for relationships. This s
  back in an important part of a player that probably cost more than $400
  1996 - around $ 32.

  So what did the people? They divided their 2 GB drive in two,
  three or more logical drives. Each of these logical drives has been
  smaller the real physical disk, had smaller clusters, and
  so less waste. If, for example, she was able to keep all the partitions
  less than 512 MB, cluster size was only 8 KB, and the loss was reduced to a
  a quarter of what it would be otherwise.

  People partitioned for other reasons also, but back in the days of
  FAT16, it was the main reason to do so.

  The present

  Three things have changed radically since 1996:

  1. the FAT32 and NTFS file systems came along, allowing a larger
  partitions with smaller clusters and so much less waste. In
  with NTFS, cluster sizes are 4 K, regardless of the size of the partition.

  2 hard drives have become much larger, often more than 1 TB (1000 GB) in
  size.

  3 hard drives have become much cheaper. For example, a 500 GB drive
  can be bought today for about $50. That s 250 times the size of this
  Player 2Gb typical 1996, about one-eighth of the price.

  What these things mean together which is the reason to be old to have
  multiple partitions to avoid the considerable wastage of disk space left.
  The amount of waste is much less than it used to be and the cost of
  that waste is much less. For all practical purposes, almost nobody does
  should no longer be concerned about slack, and it should no longer be
  has examined when planning your partition structure.

  What Partitions are used for today

  There are a variety of different ways people put in place several
  scores of these days. Some of these uses are reasonable, some are
  debatable, some are downright bad. I'll discuss a number of Commons
  partition types in the following:

  1. a partition for Windows only

  Most of the people who create such a partition are because they believe
  If they never have to reinstall Windows properly, at least they
  He won t lose their data and he won t have to reinstall their applications.
  because both are safe on other partitions.

  The first of these thoughts is a false comfort and the second
  is downright bad. See the analysis of the types of partition 2 and 4
  below to find out why.

  Also note that over the years, a lot of people who find their windows
  partition that has begun to be the right size proves to be too
  small. For example, if you have such a partition for Windows and later
  upgrade to a newer version of Windows, you may find that your Windows
  partition is too small.

  2. a partition for installed programs

  This normally goes hand in hand with the partition type 1, a partition for
  just Windows. The thought that if you reinstall Windows, your
  installed application programs are safe if they are in another
  partitions is simply not true. That s because all programs installed
  (with the exception of an occasional trivial) have pointers to the inside
  Windows, in the registry and elsewhere, as well as associated files
  buried in the Windows folder. So if Windows, pointers and
  the files go with it. Given that the programs need to be reinstalled if Windows
  the fact, this reasoning to a separate partition for programs not
  work. In fact, there is almost never a good reason to separate
  Windows of the software application into separate partitions.

  3. a partition for the pagefile.

  Some people think mistakenly that the pagefile on another
  score will improve performance. It is also false; It doesn t
  help and often I hurt, performance, because it increases the movement of the head
  to get back to the page to another file frequently used
  data on the disk. For best performance, the paging file should normally
  be on the most widely used score of less used physical player. For
  almost everyone with a single physical disk than the same drive s
  Windows is on C:.

  4. a partition for backup for other partitions.

  Some people make a separate partition to store backups of their other
  or partitions. People who rely on a "backup" are a joke
  themselves. It is only very slightly better than no backup at all.
  because it leaves you likely to be simultaneously the original losses
  and backup for many of the most common dangers: the head crashes and other
  types of drive, serious glitches to power failure, near lightning
  strikes, virus attack, even stolen computer.  In my opinion,.
  secure backup must be on a media removable and not stored in the
  computer.

  5. a partition for data files

  Above, when I discussed separate Windows on a clean partition,
  I pointed out that separate data from Windows is a false comfort if
  He of done with the idea that data will be safe if Windows ever
  must be reinstalled. I call it a false comfort that's because
  I'm afraid many people will rely on this separation, think that their
  data are safe there and so do not take measures to
  Back it up. In truth the data is not safe there. Having to reinstall
  Windows is just one of the dangers to someone a s hard disk and not
  probably even one. This kind of "backup" falls into the same
  category, as a backup to other partitions partition; It lets you
  sensitive to the simultaneous loss of the original and the backup on many of
  the most common dangers that affect the entire physical disk, not
  just the particular partition. Security comes from a solid backup
  diet, not how partition you.

  However, for some people, it may be a good idea to separate Windows and
  programs on the one hand of the data on the other, putting each of the
  two types into separate partitions. I think that most people
  partitioning scheme must be based on their backup system and backup
  plans are generally of two types: whole hard disk imaging
  or data only backup. If you back up data, backup is
  usually facilitated by the presence of a separate with data only partition;
  to save just the score easily, without having to
  collect pieces from here and elsewhere. However, for
  those who backup by creating an image of the entire disk, there is
  usually little, if any, benefit the separation of data in a partition of
  its own.

  Furthermore, in all honesty, I must point out that there are many
  very respected people who recommend a separate partition for Windows,
  Whatever your backup plan.  Their arguments haven t convinced
  me, but there are clearly two views different here.

  6. a partition to image files

  Some people like to deal with the images and videos as something separate
  other data files and create a separate partition for them. To my
  the spirit, an image is simply another type of data and there is no
  the advantage in doing so.

  7. a partition for music files.

  The comments above related to the image files also apply to music
  files. They are just another type of data and must be dealt with the
  just like the other data.

  8. a partition for a second operating system to dual-boot to.

  For those who manage several operating systems (Windows Vista, Windows
  XP, Windows 98, Linux, etc.), a separate partition for each operating
  system is essential. The problems here are beyond the scope of this
  discussion, but simply to note that I have no objection to s
  all these partitions

  Performance

  Some people have several partitions because they believe that it
  somehow improves performance. That s not correct. The effect is
  probably low on modern computers with modern hard disks, but if
  whatever it is, the opposite is true: more music mean poorer
  performance. That's because normally no partition is full and it
  so are gaps between them. It takes time for the drive s
  read/write heads to cross these gaps. Close all files
  are, faster access to them will be.

  Organization

  I think a lot of people overpartition because they use scores as a
  organizational structure. They have a keen sense of order and you want to
  to separate the apples from the oranges on their readers.

  Yes, separating the different types of files on partitions is a
  technical organization, but then is to separate different types of
  files in folders. The difference is that the walls are static and
  fixed in size, while the files are dynamic, changing size automatically
  as needed to meet your changing needs. This usually done records
  a much better way to organize, in my opinion.

  Certainly, partitions can be resized when necessary, but except with the latter
  versions of Windows, which requires a third-party software (the and the
  possibility to do so in Windows is primitive compared to the third-party
  solutions). These third party software normally costs money and not
  any point and how stable it is, affects the entire disk.
  with the risk of losing everything. Plan your partitions in
  first place and repartitioning, none will be necessary.  The need
  to repartition usually occurs as a result of overpartitioning in
  the first place.

  What often happens when people organize with partitions instead
  records are that they make a miscalculation of how much room they need on each
  This partition, and then when they run out of space on the partition
  When a file is logically, while having plenty of space
  on the other hand, they simply saving the file in the score of "poor".
  Paradoxically, therefore, results in this kind of score structure
  less organization rather than more.

  So how should I partition my drive

  If you read what came before, my findings will not come as a
  surprise:

  1. If your backup set is the image of the entire disk, have just one
  single (usually c partition :));

  2. If you backups just data, have two partitions one for Windows and
  application programs installed (usually c :)), the other for data
  (normally D :).)

  With the exception of multiple operating systems, it is rarely
  any advantage to have more than two partitions.

• scanning voltage and current measurement for Keithley 2400

  Dear all

  Hello

  can someone help me?

  Despite days nearlly10 I am option to find any program LabVIEW 2010 for sweeping the voltage and measure current who works with RS-232, I have a end not have nothing exept examples read single and multiple data. I tried to SmartData labview and changed a few prorgram gpib to RS - 232, but I couldn't.

  In another attempt to find a good VI "votltage scanning and current measurement" that work with RS-232 in labview 5.1.1. I have converted in 2008, but it takes old driver (ke24xx.dll) and do not work in my labview 2010 and I could ' t find older driver.

  My thesis project was halted in those 10 days, and I couldn't do anything for our keithley.

  Please helpe...

  in the following, I have attached these files:

  1.-first, what voltage scan that works with GPIB

  2 - Vi that I change the gpib for visa (rs232) port that I don't know why it doesn't work.

  3. it is Vi related to the "sweeping and current measurement votltage" that works with the RS-232, but it takes old dirver so I can't use it.

  4-slot-VI necessary for the implementation of program 3 (but there is no driver for these subVIs) was attached to the reply message of this post

  If any body has this program ("scan votltage and current measurement" running rs - 232) please send to me

  Thanks in advance.

  None of you attached the screws are the driver OR you spoke. There is no conversion required for this driver.

  I think that this problem may be due to my poor concept in Java. Please provide some tips.

  Note: The class DEF is a listener of bluetooth device discovery. I run in debug mode and make sure that the code executed at these lines open the accelerometer. But all return null. So I can't treat more steps.

  My target is to detect the orientation of the screen and the limit to this complementary process direction.

  Thank you for your help in advance.

  Best regards

  Albert Siu

  Fix there issue.

  The issue is due to bad I opened the channel as a channel of raw. If it throws an exception in the getorientation function.

  Thanks for your help.

  The read_geolocation tag is present in the file blackberry - tablet.xml. Any ideas? The text boxes do not show that the features are present - no updates at all.

  Thanks in advance!

  Hi maltic,

  the problem is that you're declaring variables of geo and CAC inside the constructor, then when it stops, your valuables are gone as well.

  Move the two statements to be global to the class (same place, you stated the TextFields) and you'll have it working properly.

  In addition, you should also test geo.muted, because it will tell you if your application has the rights to read the data of geolocation or not.

  I hope that helps!

• How do I access the accelerometer of the iPad on board animate?

  How do I access the accelerometer of the iPad on board animate? Need code to be able to start an animation of a label, once the iPad has been rotated by the Viewer.  Help?

  Hi, i.brown-

  Try searching the deviceOrientation event.  Christian Cantrell has a great video that talks about:

• Retrieve the tasks and events for a Virtual Machine

  Hello everyone.

  This question may seem trivial to some people here, but I cannot make it work: I would like to use VCO to retrieve the tasks and events for a specific virtual machine (IN parameter). Can someone help me to do?

  Best regards

  As I said, it must create a collector by using the createCollectorForTasks method in VcTaskManager.

  The parameter of this method is an instance of VcTaskFilterSpec, in which specify you the object to filter (in your case, the reference entity VM)

  You will get a VcTaskHistoryCollector which can only be traversed by using the methods readNextTasks and readPreviousTasks.

  // Get TaskManager service
  var sdktm = vm.sdkConnection.taskManager;
  
  // Create FilterSpec containing vm reference to filter
  var filter = new VcTaskFilterSpec();
  var spec = new VcTaskFilterSpecByEntity();
  spec.entity = vm.reference;
  spec.recursion = VcTaskFilterSpecRecursionOption.self;
  filter.entity = spec;
  
  // Create collector
  var collector = sdktm.createCollectorForTasks(filter);
  collector.resetCollector();
  
  // Browse all pages returned by collector (10 entries per page)
  var taskPage;
  while ((taskPage = collector.readPreviousTasks(10)) != null)
  {
      for each (var task in taskPage)
      {
          System.log("Task: " + task.name + " -> " + task.startTime);
      }
  }
  

• the back and are not virtual machines running on Isilon

  Hello vExperts.

  Could someone please share the details of the back and to not execution of virtual machines on EMC Isilon...

  We have a problem of IOPS / serious storage s, don't have just enough time zones and no money in the budget for more, but we have an Isilon with certain capabilities, I don't have all the details in front of me that I write this message about what nodes and others look like but soon as I have them I will add them in the post.

  For now, if someone wants to throw me some knowledge around deployment of virtual machines on Isilon before blindly go us in that direction that would be great

  Thanks for you input in advance!

  In short: not to run virtual machines on Isilon.  Been there, done that, didn't like it much at all.  You will cause you grief.

  We tried with KVM and ESXi and neither works well. EMC has tried to run, but even their its saying not to.

  I love Isilon but not not for hosting virtual machines.

• Measure the voltage and the temperature simultaneously with PCI-6281

  Measure the voltage and the temperature at the same time at the same time. However, when I put the voltage and temperature in a loop, the acquisition of voltage is significantly delayed. When I put the voltage and temperature in two different loop, none of them works.  There is an example in aid of Labview as shown. This structure works fairly quickly? In addition, how a volgate get and temperature Analog DBL 1Chan 1Samp? I check the exported excel, the first column is 0, 1 the second column contains the value of the voltage, temperature value. I wonder how can I get these two values for each scan.

  ,

  Assuming that the DAQ cards can handle it, you can set an analog trigger for the channel of the tension.  Then you just X samples to get your 100us data value.  Keep the last sample.

• Measure the period and the peak value at crest of a sine wave

  Hello

  I am new to Veristand and Labview and I was wondering if there is the possibility to do the following:

  I would like to measure the period of a sine wave that I capture from analog input of my data acquisition (SMU-6363). Apart from that, I also want to measure the value of crete to crete (Vpp) of the sine wave.

  I hope you can help out me.

  Thank you.

  If the sine wave is of significantly higher frequency than the primary control loop can run... The best way to do it would be to put the DAQ hardware in waveform input mode and use a custom device to read the waveform and perform analyses.

  an example is here: requires some labview skills
