Cut within the specific range

Hello

I use MCdaq201 to acquire the signal of a photodiode. What I see in oscilloscope, is a beautiful sinusoid!, exactly what I was expecting. Then, I connect it to PC via MCdaq-USB201, I see a signal which is as he was cut in a specific range. I've attached a screenshot of the output of the program labview and tracerDAQ. Anyone know what could be the reason?

Thank you

Petar

Thanks a lot for all of your helpful tips, YES! We used a preamp between the photodiode and the DAQ hardware and acquired the desired signal.

And I am really HAPPY!

  • definition of text within the specific Web div object

    Hello!  I am trying to find a way to take the text of a text caption and assign it to a specific div inside a Web object.

    I tested it with a site regular html with embedded iframe and it works fine, but with Captivate, I can't get the text to a web object.

    The WebObject is named CC_box and inside, there is a div tag with an id of 'text' - this is where the text should go.  The text caption containing the text is named CC_source_1 for the first slide, then CC_source_2 for the next, etc.

    Here is my code:

    var slideNumber = window.cpAPIInterface.getCurrentSlideIndex ();                                Gets the number of the current slide

    var ccText = document.getElementById("CC_source_"_+_slideNumber).textContent;     Retrieves the text of a legend of text on a page in progress - works fine

    $("#CC_box).contents ().find("#text").html (ccText);                                                          This line of code works perfectly in HTML, but not in Captivate

    What is a good way to access this div within the web object of Captivate?

    Thank you!

    Thank you, I'll try that!

    in the meantime I kept trying different things here and found that if I go 'deeper' and call iframe directly as opposed to a container div, everything works, so in this case the following worked:

    $("#myFrame_CC_boxc").contents ().find("#text").html (ccText);

    Interestingly, Captivate attached a 'c' at the end of the name of the div, so even if I named the CC_box of Web object, we call it actually CC_boxc if you look in the DOM Explorer

  • specific range

    Hello

    I have some data (depending on the frequency Magnitude), I want to simply select the points that lie within a specific range (frequency... Category axis), for example, I want to filter the signal only for points that are between 20 and 30 Hz. Someone know how I can do?

    I used "line and force", but it gives the 'threshold' for points that don't are not in it rang. I don't want to choose which points.

    I got appreaciate it.

    Thank you

    Petar

    Hello

    I think you can try to use a loop For instead of the function "in range and force." Simply enter your data in the loop, and using a tunnel conditional you can compare the data that you want. I have attached a picture of a small example, I created for you to see.

  • Get number of records in the date range - IDE: PLSQL Developer

    I want to count the number of records of members who register within a date range specified, based on effective and expiration dates and their "elg_code". I posted the SQL code for some examples of data. What I would like to see returned is in three columns of the counties where the eff_date date_exp members fall within the date range specified by the SQL and have an Elg_code of ' ' (space).

    So what I would like is all members with elg_code ' ' where he eff_dt and exp_dt range is April 2012, 2012 MAY & JUN 2012. Thus, according to data from the sample I posted, Mark, where his elg_code record is ' ', his eff_dt is 01/01/2011 and April 2012 (30/04/2012) is his exp_dt. Range of the brand statement may 2012, but not MAY or JUNE of 2012. Marty would tally for the APR and MAY because his eff_dt is before MAY 2012 and his exp to MAY 2012. etc...

    According to the data below, the results should resemble:

    APR MAY JUN
    4-3-2

    APR should have FRANK, MARK, MARTY, MARY.
    MAY should have FRANK, MARTY, MARY
    JUN should have FRANK and MARIE

    NOAM and JOHN should not appear as his records with elg_code ' ' have no documents eff_dt and exp_dt which are April-June 2012.

    So what I tried without success as it appears that I have a kind of Cartesian question (?), is:

    Select count (m1.mbr_name) APR,
    Count (m2.mbr_name) MAY,
    Count (m3.mbr_name) JUN
    mbr2 M1,
    mbr2 m2,
    mbr2 m3
    "where m1.eff_dt < ' 01 - may - 2012"
    "and m1.exp_dt > ' 01-Apr-2012.
    and m1.elg_code = ' '
    "and m2.eff_dt < 1 June 2012"
    "and m2.exp_dt > ' 01 - may - 2012"
    and m2.elg_code = ' '
    "and m3.eff_dt < 1 July 2012"
    "and m3.exp_dt > 1 June 2012"

  • I'm new to Lr, can someone tell me if there is a limit of size PRACTICE to a Lightroom catalog file? Should I keep the file size within a certain range of size of GB and then create a new? Thank you I would be grateful of any advice.

    I'm new to Lr, can someone tell me if there is a limit of size PRACTICE to a Lightroom catalog file? Should I keep the file size within a certain range of size of GB and then create a new? Thank you I would be grateful of any advice.

    He has no such limit, and in fact some users in this domain and other forums report catalogues over 1/2 million pictures works well.

    The idea to create multiple catalogs because you don't want to get too big catalog file size is a bad idea that you should never think of it again.

  • Refresh the components within a specific line of an af:table programmatically

    How do I refresh the components within a specific line of an af:table programmatically without refreshing the entire table? _

    I have an af:table to display a view read-only object. There is a button change in the table by calling an af:popup, where the user can update the information and click on a submit button to commit its changes.
    The action of this button property is a method in a holder in the summer where
    -1: a stored procedure is called to update several tables (related to my read-only VO).
    -2: the VO is re-interviewed (refreshQueryKeepingCurrentRow() VO.)
    -3: updating of the whole table (AdfFacesContext.getCurrentInstance () .addPartialTarget (myTable))

    Is it possible to programmatically refresh some components of the current row in the table without refreshing the entire table (point 3)?

    I tried to play with the property "partialTrigger" to af: outputText (table: column: outputText), without success.

    Thank you

    Nicolas

    OK, that's a very clear answer, thank you.

    Now, first do a little optimization:

    if(!StringUtils.isStringEmpty(results) && results.equals("TRUE"))
    // should be
    if ("TRUE".equals(results))
    // since it's faster, simpler and requires one less dependency
    

    For your use case, you can say you want to always refresh the line, then you could link the table in your backing bean, retrieve the selectedRowKeys and then set the key for the current line on the model in the collection before adding the partial target. So, something like:

    Set selectedKeys = table.getSelectedRowKeys();
    assert selectedKeys.size() == 1;
    Object old = table.getRowKey();
    try
    {
        table.setRowKey(selectedKeys .iterator().next());
        addPartialTarget(outputText);
    }
    finally
    {
        table.setRowKey(old);
    }
    
    

    p.s. I checked the table rendering code to be sure and partial updating of the contents of the line must be possible without refreshing the entire table.

    Kind regards

  • Filling of the specific category of Signal on the range of functions

    Hello

    Does anyone can help with advice on how to complete the specific category of signal on the palette of functions of block diagram?

    Thank you

    Hi Ewan,

    Uninstallation and reinstallation in order would ensure that everything was properly associated. However, I don't think that this should be necessary in your situation. Please go to control panel > programs and features > National Instruments software to see the full list of National Instruments software you have installed. From there, you should be able to select any individual installation from the list and select "repair". Instead of just seeing that something is already installed and the output, it should go through the installation and check alteration. In addition, this should add the correct associations if they were currently missed due to the order of installation.

    Please try to run a repair of 2013 SignalExpress and restarted your computer, then check if the LabVIEW function palette is completely filled.

    Thank you!

  • Through remote access vpn Ipsec within the host is not available.

    Team,

    I have a question in confiuration vpn crossed.

    ASA 3,0000 Version 5

    the only question is, to access remote vpn clinet IP cannot access inside the host. However able to reach the branch of IP and it uses corprate Internet.

    In SAA from the external interface I am able to ping remote clint IP but not from within the interface. Please help and let me know if additional information is required.

    Thank you

    Knockaert

    Hello

    For the NAT0 configuration, you only need NAT0 instruction for the interface "inside".

    This single command/ACL should allow for 'inside' <-->'vpn-pool' communication.

    NAT0 configurations on the 'external' interface should be necessary only if you make NAT0 between 2 VPN connections. I guess you could do this since you mention traffic crossed?

    I suggest using different 'object-group' to define networks of NAT0 destination for different ' object-group' to the 'outside' to 'outside' and 'inside' users NAT0.

    I also obsessively using beaches too wide network in the statements of NAT0. According to some records, they can cause problems

    For example, this network ' object-network 172.16.0.0 255.240.0.0 "contains the 172.x.x.x.x set private IP address range. And in this case it contains some of your 'inside' networks too?

    How is this a problem of crossed by the way? You say that the problem is between the VPN clients on the 'external' interface and network local hosts behind the 'internal '? Crossed would mean you have connection problem between 'outside' <->'outside' perhaps.

    I don't know if I made any sense. Can be a bit messy. But can not give very specific answers that I don't know the entire configuration.

    Also make sure you have the "inspect icmp" configured under the policy-map of the world, so that the response to ICMP echo messages are automatically allowed through the ASA.

  • Change the assets of the library within the program without affecting cloud related files

    Hello

    I use creative cloud under Mac OS x, and all programs are up to date. I have a two part question.

    1. is there a way to edit a library asset in an Adobe program without affecting the linked file cloud? If so, how?

    2. If it is not possible to do it, what is the best practice to edit a library resource without affecting the linked file? Do I have to include the file in the document? Create a new asset with the adjusted attributes and use this asset?

    As an example of what I'm trying to do, I have a logo in a creative clouds library that I use in an Illustrator document. The asset is black, I want to make the Pantone color blue of the company within the Illustrator, however it won't let me change locally. It seems that I have to open the file in the library, adjust it, save it and use that asset. However, I do not want this asset related to change of color in all other documents I used it. So, what I did is to save an asset separate cloud with the logo like this color. This seems unnecessary and unsustainable. Whenever I have a variant of a cloud asset should not require save me a new version of it for this specific use. My library will get crowded, fast.

    If it is not part of the works the library assets, in my opinion, it should be. Be able to adjust an asset at the local level, even if it's a range a minimum of settings without changing the attributes of the linked file, seems to be obvious.

    Ah, that's useful. I had not tried. At least it's easier than opening assets and by copying and pasting from there. Thank you for your response.

    I wish that it was possible to change the appearance of a related assets without changing the assets in the cloud. This way if something has changed on the assets 'overall' it could be changed and reflected in each document, all keeping this attribute "local." This feature cannot currently? I just want to make sure I'm not missing something.

  • Design Muse &amp; change within the catalyst company

    Hello world

    Apologies from the start for beginners question however, I struggled to find a topic that describes perfectly the relationship between BC and Adobe Muse. I created the site of Muse and satisfied with the appearance of the site, I just realized that when published in British Colombia, I give myself a few restrictions tightened, for example I can't create pages or modules in the admin of BC... the options just aren't there, I can see web forms, I created however. Do I have reason to think that you are not allowed to completely change the content?  Adobe wants you to make the updates within the Muse and then download the site every time. However, when you want to get forms, client and job connections most advanced features I'll need to make specific changes within the BC and among the markup, i.e. which means "enabling editing options.

    Therefore, it means you need to design sites of Muse, pull them in British Colombia and work above, simply from BC? I don't see how you can maintain a link between the Muse and British Colombia because Muse is a software design and British Colombia is a CMS... they do different things.

    The question is, I have set up a range of forms, a secure connection, develop more content in British Colombia and then I want to do a major design change which means ebb in Muse and overwrite everything that has just been setup... y at - there something I'm missing or is this how it works?

    I would appreciate any help on this matter,

    Thank you very much

    Sam

    Hi Sam, you can go into the settings and enable editing.

    The reason for which it is set up to be restrictive is good because they programs like muse create sites, yes they make nice but they are not really functional Web sites. But you'll find this clunkyness tries to use BC as a CMS and creation of the site through Muse. Just as many more securezones, eCommerce, blog... and more will just become increasingly problematic to say the least.

  • Cut out the background, brighten the image and the image speed

    Hello world

    I'm sure it's a very simple answer, but I'm new to photoshop and have searched for a solution to this problem for a while. There seems to be so many different ways to approach it, I thought that I would ask you guys what you think and get a specific answer to my problem.

    ------------------------------------------------------------------------------

    I took a picture of my products with a good camera located on the highest image quality in a lightbox. I then want to take this picture and cut out the background (make white) and brighten the image of the products themselves. This image is then used on our posters, banners, floor stands, brochures... Made on a range of promo material and, above all, to a range of different sizes.

    I took the image in photoshop and used the tool to select around the edges, then used "curves" and another adjustment (I forget which) to make the space around the white image. Then I inverted the selection and used the same settings to make the image itself slightly brighter.

    I sent it to a printer, and they said that because I had used this process, the background I made white may not be the right shade of white printing and appear as a different shade, a box around the product on the banner (although I printed on my printer at home and I can't notice a different shade). They also said that my image was not clear enough, and he had to be 300 DPI instead of the 72 dpi that my camera took the picture. (I posted about this problem of IPR before and got useful answers, but now I'm starting the process of zero thought I would mention it again)

    I have attached the original photo and also the picture after my editing on photoshop for reference. Both in low resolution.

    So to summarize, I need to get my products on background photos, brighten them up and make them 300 dpi then don't complain printers!

    Any help would be greatly appreciated. Thanks in advance.

    Kind regards

    Jamie

    Below: Shot Original camera file format original 72 dpi is 7MB

    IMG_2203LR.jpg

    Downstairs: shot after having been edited in photoshop. Although I have no more the .psd of this file. Only the .jpeg

    4Pack V2LR.jpg

    He had to be 300 DPI instead of the 72 dpi that my camera took the picture.

    The PPI (better word than IPR) makes no sense without the physical dimensions of print to go with it.

    You mention the different print sizes. Not all should be 300 PPI. (Large banners or posters may work properly at lower pixel density)

    Can you tell us one or two sizes of output?

    And, most importantly, tell us the Pixel size of the file? (Image > Image size > width and height in pixels)

    As I said in your other post, you have rhythm. But I need to know the target print size and the size of the file in pixels.
