Extremely slow camera in MAX and the software response

I am in the process of upgrading from a piece of test equipment that uses two firewire cameras.

Currently, the software is written in LabVIEW 7.1, it uses NEITHER IMAQ and is quite catchy, with little perceptible delay in the passage between the cameras in the software. Same MAX opens up the cameras relatively quickly and you can turn on or take a few seconds of clicking cameras and quickly change between cameras.

Without changing the external hardware to the computer, but with a new windows 7 PC in place and update the software to use OR-IMAQdx simply by replacing the IMAQ works with IMAQdx in 2014 of LabVIEW and install the latest version of MAX led the software becomes unusually slow in the passage of the cameras. When I say exceptional, I mean that it takes up to 30 years to set up and run each camera. Bearing in mind that the vision process takes 0.5 seconds or less is unacceptable. It is just as painful changing between cameras in MAX.

I noticed that on another system that uses a camera USB 3, simply by clicking on the camera icon in MAX takes a LOT of time answering to allow you to do anything.

On the old windows PC with MAX 5 and IMAQ clicking a camera brings the dialog boxes fairly quickly.

Someone has an idea, what happens? Is it something IMAQdx? Of course, this is not normal?

Can anyone offer advice please?

Thank you

Your post, I shared with my colleague FireWire camera (which is out of town, but regularly check the email), and here's his reply:

Three cameras at 25 frames per second, with RGB channel separated because of the bandwidth.  We take avi and pngs simultaneously on several channels.  My suspicion is that their former Council might not be fully compliant with the standards. Not all the work of commissions, I tried a little on-site, then chose the one that is recommended by the seller.  In addition, no hubs as they can also stifle bandwidth.

Hope it will be useful.

    What is the difference between a version of MAR and the software win7 INKL?

    Hello

    Thanks for posting your query in Microsoft Community.

    • What exactly you're talking about when you say, 'Version INKL of Windows 7?

    I'll be happy to answer your query, however, please explain more about abbreviation INKL. There is a version called Office of ink that is used in the Tablet PC.

    Here's the other version of Windows, you can make reference to:

    MAR - Microsoft Authorized Reacondicionador

    A new PC requires a version of windows with a new key license installed if purchased from a manufacturer.

    A refurbished PC is allowed to use an existing product key (2nd hand if you like) as long as it is always delivered with a certificate of authenticity (COA). This is referred to as MAR (Microsoft authorized Reacondicionador) which means that Microsoft allows to use existing keys/licenses products.

    Buy a version of windows means MAR technically you buy a second hand copy - being however, software, so it comes with COST, will make absolutely no difference at all.

    N and KN editions

    The features in N and KN Editions are the same full versions of their equivalent, but do not include Windows Media Player or other technologies related to Windows Media, such as Windows Media Center and Windows DVD Maker because of the limits set by the European Union and South Korea, respectively. The cost of n and KN Editions are the same as the full versions, as the Media Feature Pack for Windows 7 N and Windows 7 KN can be downloaded for free from Microsoft.

    Generations of VL

    VL builds work with VLK (volume license key). Volume license keys can be used to activate multiple installations of the software without a mechanism (for example, a product activation mechanism) controls the total number of facilities. The license for the software is going to impose restrictions on the use of the key. In general, the license will limit the key to a certain number of facilities which must be only the Organization of the licensee and also to place the holder under the obligation to keep a record of the number of facilities, hold confidential and perhaps even require that the holder organization makes available for a software license check check that his use of the key is in the terms of the license.

    Please let us know what exactly are you referring to when you say version INKL of Windows 7, so we can further research and answer.

    Hope this information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.

  • BlackBerry Smartphones Blackberry Bold 9930 update failed and the software does not load

    I have a Blackberry Bold 9930 and yesterdasy I received a msg saying to upgrade to 7.x software Blackberry. I followed the instructions (takes too long like 2 hours to download) and then. Big mistake because it cooked my phone. It seems that when you upgrade, the upgrade process goes thru, but stops after the time zone to restore the process and reports an error 602 with a reset button to reset your database. The reset button does not work and I restarted the phone to restore the db. At the moment that it restarts, launched the process, and even once, it failed after the msg indicating time zones (100% and overall restoration treatment 7%). Zones roughly completed, but then I got a msg saying I wandered 602 belive. On all courses was about 5 to 10 percent. Now my phone is undesirable because it does not restart. Verizon says they have a large number of phones across the country, but BlackBerry says it's a matter of Verizon...  Someone at - he already heard of this I am now without such a 4 days while I get a replacement Friday because of the holiday...  I am not very happy as another question, I found - during the upgrade process it used the cells instead of my wirelss home network to download the software and it really took about 2 to 3 hours, then another hour before it failed during the upgrade process. So about. 3 to 4 hours to play with an upgrade yesterday.

    Thank you

    Hello merlin02131

    Welcome to the Forums of the BlackBerry Support

    Sorry to hear about the problem you are experiencing during the update!

    But you can still use Desktop Software for the update process, personally, I prefer never to do an Over the Air update. I think that something has gone wrong with the update process and thus you encounter this error 602.

    You have a backup of your device, or using BlackBerry protect for the backup?

    If you wish you can try several method to recover your device of this error, all you need is a PC and an Internet connection active. But attention, this method deletes the data user in this device. This is the Knowledge Base to follow:

    KB10144 : How to force detect the BlackBerry smartphone using the Application Loader

  • Extremely slow synchronization of index of the substring

    Oracle on RedHat Linux x 64 11.2.0.2 (5,7)

    I created a partitioned CONTEXT index in a NOPOPULATE State.  The index is defined on a column of a table partitioned using an attribute NULL_FILTER and SUBSTRING CLOB.  I then used the following procedure to fill the files queued for indexing.

    BEGIN

    CTX_DDL. () POPULATE_PENDING

    idx_name = > "CONTENT_VALUE_IDX"

    part_name = > 'P_2012_12 '.

    );

    END;

    /

    This procedure seems to work for an appropriate period of time, but ended up with the following error:

    ORA-20000: Oracle text error:

    DRG-50857: error Oracle in drvddl. ProcessOnlinePending

    ORA-20000: Oracle text error:

    DRG-50857: error Oracle in textindexmethods. ODCIIndexDelete

    ORA-20000: Oracle text error:

    DRG-50857: error Oracle in drdmlpo

    ORA-20000: Oracle text error:

    ORA-06512: at "CTXSYS. DRUE", line 160

    ORA-06512: at "CTXSYS. DRVXMD', line 42

    ORA-06512: at line 1

    ORA-30576: dictionary of the context error loading Option

    ORA-06512: at "CTXSYS. DRUE", line 160

    ORA-06512: at "CTXSYS. CTX_DDL', line 1366

    ORA-06512: at line 2

    However, the number of records that have been entered in the DR$ PENDING corresponded with the same number of records in the table that is to be built on this index.  So, I hope that this error can be ignored?

    I then try to sync the lines on hold with the following text:

    BEGIN

    CTX_OUTPUT. START_LOG ('content_value.log');

    END;

    /

    BEGIN

    CTX_DDL. () SYNC_INDEX

    idx_name = > "CONTENT_VALUE_IDX"

    memory = > "2000 M",

    part_name = > "P_2012_12"

    parallel_degree = > 16

    );

    END;

    /

    The process begins in parallel 16 and logs show the documents being indexed.  After about an hour or two, the paper then shows "Writing data index ($I) to the database." and then appears to process the data of the substring that the log shows "Substring writing data ($P) to the database."  This is the point that the parallel process begins to go to series.  Restraint begins to show in the data base.  Blocking the session indicates an expectation of 'db file sequential read' event and the sessions that begin to queue have a wait state of ' enq: TX - line lock conflict.

    $P TEXT table support is being filled and lines are deleted from the DR$ waiting for the table, then the process does work.  The partition which was being indexed has only 27 lines, however the process lasted a few WEEKS before I finally killed the process.

    There is a note on Metalink (parallel and series SYNC_INDEX text is slow when SUBSTRING_INDEX is enabled (Doc ID 840097.1)) which seems to solve this same scenario, but says that the problem should be solved in 11.2.0.2.

    Another sync non-text substring index with no problems.  The 'Oracle Text' option is valid in the data base and none of the CTXSYS objects are DISABLED.

    Someone at - it ideas?

    So, as you guessed correctly, the fundamental problem is that 16 parallel workers try to write to the table in the face of the claim and the substring by.

    Our solution has been to change the parameter MAXTIME sync_index something very short - a half hour - so that the amount of data to write was a little smaller and the claim was broken up more quickly.

    We did originally because we wanted more insight in the newspapers and the pace of progress in the indexing, but after testing with multiple values MAXTIME, we found that 30 minutes gave us the best overall in terms of indexed documents throughput / hour.

    Your values will likely change, but with a bit of journaling, you should be able to find a practice, if a solution is not optimal.

  • Loading EXTREMELY slow page - perhaps due to the jpg in png re-optimizing Muse?

    The team of Muse, please help and advise.

    I use a bunch of effects of transparency, shadow and bevel on the pictures in my site, and the loading time is horribly slow. I guess because of the png that Muse has created to achieve some of these effects - some of them are more than a MB in size! I tried to open the png generated by Muse and re-optimize-the to the down in Photoshop, but whenever I have transferred the png to size down in my FTP, they bloated back up again. The site in question is www.chuckburgi.com. It contains 5 png bloated semi transparent and I see them as size down on my desk, but they swell to their original huge size when I their FTP or put them on Dropbox. How can I solve this problem?

    Thank you!

    Not a bug I think.

    When a widget of composition is to 'See the target on rolling' driving on the trigger, it is active and therefore the rollover State is to never show. The trigger goes directly to the Normal State to the active state.

    In addition, you really want to use two (or more) images, if you can avoid it. With the help of opacity of the object you can just have a unique background image and thus half http requests and half of the image to download data.

  • Min - Max and the planning of Kanban

    What are the factors or business cases that should be considered in the choice of planning that we should go?
    Any help would be appreciated

    My Client is interested in the above 2 methods

    Thank you
    Mahendra

    It of a broad question and is not easy to answer.
    One major difference is your philosophy.
    Kanban (if properly implemented) is pull based system.
    Min - max is always anxious that is it looks at your current onhand, future demand, future supply and then comes up with a purchase requisition.

    But there is no hard rule.

    Min - max works well when the issue of subinventory is not placed in a compartment. But in a workshop type of situation, you can have an operator goes the CRUDE inventory to get a bucket of screws.
    If you ran min - max on the WIP subinventory, he will think that you have a lot and does not generate a purchase requisition.
    But another operator may require that these screws and it may be out of them. In this case, a Kanban work better because as soon as the first operator took the last nth bucket, Kanban would have triggered the replenishment process.

    Kanban requires you to spend the time to analyze your problems to get to many of bin sizes and locations.

    The general rule is that Min - Max is simpler to implement.
    Kanban is a bit more complicated. So if your organization is not not mature enough or requires a simpler solution, min - max will work better.
