• How to trigger the camera and light pulsed with PCIe-1427

  Hello

  We recently bought an acquisition card NI PCIe-1024 and the NI Vision Builder.

  I am new to imaging applications and need support to get started.

  Application:

  We have a camera viewing a scene which is illuminated by a pulsed light source (e.g., a strobe).

  We want to use the PCIe-1427 as the master for the outbreak of the camera and strobe light.

  The first trigger (Ch 0) transmitting signals TTL to camera to 30 Hz (30 fps).

  The second trigger (Ch 1) send bursts of pulses to the strobe light to e.g. 10 kHz. This trigger must only send impulses all other images, so that we can save alternating light and dark images in order to perform background subtraction.

  I tried to set up the channels of the trigger and create virtual channels in the measurement and Applications Explorer, but apparently this is not possible.

  Since it is an application critical time, I'd appreciate an example vi that sets up the channels two trigger and download managers in the camera to get started on this application. Thank you.

  Software of NEITHER: LabVIEW version 10

  Materials: Device for the Acquisition of Image (IMAQ) PCIe-1427 driver Version: NOR-IMAQ 4.4 OS: Windows 7

  Thank you, Justin.

  I'll copy this request to the machine Vision Group as you suggested. I looked at the link sent you me and made progress (limited). I can see on an oscilloscope trigger signals, and the camera acquires images. However, I only managed to do work for pulse trains continuous, not a shots or bursts of pulses.

  No need to answer that. Thanks for your help.

• How to turn the relay for a DT80?

  Hello, I am a complete newbie to Labview.  I am currently taking data from a DT80, which, from my understanding, is interpreted as a TCP.  My question is: is it possible to disable the relay of Labview, via a switch?  Even after that performance data are stopped, it continues to analyze as evidenced by a rattling really annoying that comes on when I start the code for the first time and does not turn off until I have disable the machine itself.  Any help is greatly appreciated!

  Look at page 170 for how to access the relays via modbus.

  Looking at page 196, it resembles 1RELAY = 0 or 1 RELAY = 1 are the commands to activate it works.

• How to detect the number of created quickobjects

  How to detect the number of quickobjects created? quickobject are quickbox2d.

  Basically, I have a timer that will countdown to 4 seconds and it will create a falling ball, it will get removed when she falls down. However, I want only there so that if more than 5 bullets are in step, it will cease to create until it is less than 5 to start creating some balls again. Is there a way I can do?

  It's the timer to create the ball

  If (! _ballCreation_timer) {}

  _ballCreation_timer = new timer (4000);

  _ballCreation_timer.addEventListener (TimerEvent.TIMER, _onBallCreationTimer);

  }

  _ballCreation_timer. Start();

  Function which create the ball based on clock

  function _onBallCreationTimer (e:TimerEvent): void {}

  _doCreateNewBall();

  }

  function _doCreateNewBall() {}

  _ball_quickobject = sim.addCircle ({x: PHYSICS_SCALE * (960), y: PHYSICS_SCALE * (10), RADIUS: 0.5, draggable: false});

  MAKE A LIST OF BALLS

  _balls_array.push (_ball_quickobject);

  }

  This is the part where if the table (QuickObject) ball falls down and are destroyed

  addEventListener (Event.ENTER_FRAME, _onEnterFrame);

  DRAW EACH BALL FALLING OUT OF THE SCREEN

  function _onEnterFrame (aEvent: Event): void {}

  for each (var quickObject: QuickObject in _balls_array) {}

  BALL FALLING OUT OF THE SCREEN?

  If (quickObject.y / PHYSICS_SCALE > 1080) {}

  _doHandleBallOffScreen (quickObject);

  }

  }

  }

  DESTROY THE BALL FALL OFF THE SCREEN IF

  function _doHandleBallOffScreen (aQuickObject: QuickObject): void {}

  DESTROY THE OBJECT

  aQuickObject.destroy ();

  REMOVE FROM THE CUSTOM TABLE

  _balls_array.splice (_balls_array.indexOf (aQuickObject), 1);

  }

  check the length of _balls_array.  If it is greater than 5, do not create another bullet:

  If (! _ballCreation_timer) {}

  _ballCreation_timer = new timer (4000);

  _ballCreation_timer.addEventListener (IMER TimerEvent.T, _onBallCreationTimer);

  }

  _ballCreation_timer. Start();

  Function which create the ball based on clock

  function _onBallCreationTimer (e:TimerEvent): void {}

  _doCreateNewBall();

  }

  function _doCreateNewBall() {}

  If (_balls_array.length<>

  _ball_quickobject = sim.addCircle ({x: PHYSICS_SCALE * (960), y: PHYSICS_SCALE * (10), RADIUS: 0.5, draggable: false});

  MAKE A LIST OF BALLS

  _balls_array.push (_ball_quickobject);

  }

  }

• How and when the computer turns off automatically?

  Listen to internet radio, Sys Pref > saving energy on the default setting, wake up and radio program cut.

  This is great... .buth how and when the computer turns off?  When I reopen it wifi comes back, I'm correct when she stops she also turns off wifi?

  Hello allan299,

  Thank you for using communities of Apple Support.

  According to your post, I see that you have any questions on how and when your computer shuts down, and how the WiFi on your Mac is affected. I know it's nice to be able to properly manage what happens when your computer stops and starts in mode 'sleep'. I'm happy to help you find the best resolution.

  You're right, when your computer stops completely it will turn the Wi - Fi. If you enable the wake for network access, Wi - Fi remains lit, and you can access shared resources on your computer, such as printers or iTunes shared playlists even when your computer is in "sleep". Definition of a calendar closing and start on your Mac can also be useful.

  Check out the following resources that will help the set options that control the energy use of your computer, sleep, and wake-up times for your Mac and the calendar from your Mac to turn on or turn off or go to sleep:

  OS X Yosemite: energy saver Preferences

  OS X Yosemite: set sleep and wake up on time for your Mac

  Best regards.

• How to get the video intro off my google home screen I already saw it, where is the firefox logo used to be.

  How to get the video intro off my google home screen I already saw it, where is the firefox logo used to be. I started with the last update that I rebooted.

  Hello
  to change the homepage when opening firefox-press 'Alt' and click on tools-> Options.

  Main menu, you can change the URL.

  If the problem persists, you can follow these simple steps:

  Enter about: config in the address bar and press ENTER. Accept the message of 'dragons' to see the Advanced preferences screen. Use the above search box to enter the below pref.
  

  You can assign an empty string to stop your Firefox to retrieve "extracts" and brandLogo changes the browser.aboutHomeSnippets.updateUrl pref. Right-click this pref and select Edit then clear the value as pref in the box that appears, and then click OK. Who will also disable "snippets" that appear under the container of the research on the default home page.

  Then you must open the folder of your profile, via help > Troubleshooting Information > profile folder > > button view folder. Then close Firefox. Your profile file open with Firefox closed (Firefox '3-bar' menu key > exit/Quit), wait or two minutes, then remove the storage\moz-safe-about + home folder in the Firefox profile folder to remove the brandLogo and stored in IndexedDB code snippets to make Firefox use the default brandLogo and a defined default code snippet.

  If you later change your mind about these changes, you can reset the pref browser.aboutHomeSnippets.updateUrl via the context menu and Reset allows to retrieve the default value using the storage\moz-chest-fort-about + home folder again.

• How to detect the color pages in a PDF file?

  I use a plug-in of Acrobat C++ read/modify a PDF file.

  I need to get the total number of pages in the PDF file and the page numbers of the pages in color.

  So far, I was able to get the total number of pages using PDDocGetNumPages() with no problems.

  However, I can't find an API that lets me know if a particular page is color or not. Is there a way to do this?

  Thanks in advance!

  But what happens if there are RGB data which means black or grey (R == G == B), that means black or RGB?

  There is a code sample in the SDK to browse content in the PDF file, and then you can get the color space and color of each object.

  But you really need to do background research on the colors & spaces to achieve this properly.

  How to change the extensions on several files with Windows 7?

  You hear no doubt, is that your movie software will only recognize certain types of image file formats.  If this is the case, you will need to reformat format files to any format PNG is recognizable by the software.

  Rather than we guess, please identify your «film» software

  Download and install IrfanView, which is a free utility for images.  http://www.IrfanView.com/

  IrfanView has the ability to read a great many formats of image files.  It can also convert image files formats.  And even better - for you - it can do all these things on a batch of files.

  As test, after I installed IrfanView, open one of your PNG files.  Now click on file > save as, and select the 'Save as Type' to be little matter the file type of your movie software will accept.  Save the file.  Make sure your movie software can accept the new file.

  Once you are convinced that you can modify files that you have in a format that you can use, use IrfanView

  File > Batch Conversion/Rename command.  If necessary, see IrfanView help on this topic.
