What is a simplified way to explain a shift register?

I'm having an engineering evaluation tomorrow and i need to know what the easiest way to describe a shift register would be.
Solved!
Go to Solution.

Of course there's always the LabVIEW Help:
Shift Registers
Use shift registers when you want to pass values from previous
iterations through the loop to the next iteration. A shift register appears as a
pair of terminals, shown as follows, directly opposite each other on the
vertical sides of the loop border.
The terminal on the right side of the loop contains an up arrow
and stores data on the completion of an iteration. LabVIEW transfers the data
connected to the right side of the register to the next iteration. After the
loop executes, the terminal on the right side of the loop returns the last value
stored in the shift register.

  • What is the best way to explain Indesign in a four minute presentation?

    I have to give a four minute presentation on a technology (in this case InDesign) in class. How do you cover such a broad technology in four minutes? Suggestions would be great!

    You could investigate the problems in trying to reconcile "old" technology of creating physical pages, of a fixed size and without any other interactivity than turning the page, with modern variants where page size is non-existent, interactivity is *expected*, and there is no such thing as a fixed font, font size, or page orientation.
    InDesign's original purpose was to create "old" technology books, but recent versions claim to be of use for other media as well. Discuss overlaps and differences.
    (For a good look on one of the problematic areas, you can search this forum for the eternal confusion on "what is a pixel, actually?")

  • What is the proper way to record line numbers in Master/Detail records?

    Guys and Gals,
    Been thinking about this for awhile, but thought it best to ask the people who really know what they are doing.
    What is the proper way to record & show line numbers in a Master / Detail record set?
    For example, take Master/Detail relationship Orders and OrderItems. Orders has a column Document_Number and OrderItems has Document_Number, Line_Number. Line_Number should contain the row number 1,2,3,4 ... etc. for each row in a document.
    Should I ...
    <ol><li>Add a sequence and a trigger in the database? The FusionOrderDemo does this, but then the sequence never "resets" and I've got row numbers that keep incrementing. So one document has rows 4,5,6 and the next document has 7,8,9 when they should both have 1,2,3.</li>
    <li>Programmatically take care of the row numbers? This seems like I'm asking for trouble. Anytime an insert or delete operation gets done, I'll have to iterate through rows and re-assign row numbers.</li>
    <li>Is there a way to assign row numbers in a table iterator (or data collection?) to an entity?</li></ol>
    Any suggestions would be appreciated. It's looking like #2 is my only option, but if anyone knows different I'd love the input.
    Will

    Thank you both guys.
    As John said, I believe I'm looking for a gap-free sequence per master record.
    The line number of the OrderItems table is the second half of the primary key. The first half of the primary key (DocumentNumber) is the foreign key to the Orders table.
    Think of it like line items on an order or invoice. For example, if you were talking to someone on the phone concerning an invoice, you might say, "The pricing for line item #3 is incorrect." In this case, it's good to have a common reference. Or imagine a Microsoft Excel spreadsheet with no row numbers displayed! You'd never get anywhere if you had to explain something over the phone.
    If this is tricky to perform, I take it using a sequence and trigger such as the Fusion Order Demo is the best way to approach the challenge for simplicity's sake?

  • I am using Iphoto 11 ver 9.4.3 on mac using oxs 10.8.5 i want to export calendar projects to an external hard drive. what is the easiest way to do this? i have tried export and import but it didn't seem to work.

    I am using Iphoto 11 ver 9.4.3 on mac using oxs 10.8.5 i want to export calendar projects to an external hard drive. my goal is to store them in an external hard drive so it doesn't use up memory on the mac hard drive. is it possible to copy the specific projects without copying the entire library? what is the easiest way to do this? i have tried export and import but it didn't seem to work.

    What do you not understand?
    You can duplicate the iPhoto library (command - D ) and delete everything except the project and its photos from the copy and move that
    Or
    However the calendar takes very little space - it is simpy database entries - it is the photos in the calendar that take space - and for most people you would wnat to keep those photos in your library
    you can use a photo in 50 calendars and it still is only one photo in your library - as I explained calenders do not exist as such - they are simply database entries telling iPhotop how to display the calendar - they take almost no space at all

  • What is the best way to organize photos? iPhoto or Aperture?

    I am a mom taking tons of photos of my young children. On my old PC I used to organize everything within "My Pictures" by Month & Year (May 2008). I am a very organized, linear person and don't like to change the way I do things midstream so I am having a hard time figuring out how to organize our family photos now that I have switched to a Mac with iPhoto and Aperture. In the future I hope to learn about Aperture's professional tools (which as a mom & not a professional photographer I currently do not use). I would love to take photography classes at a local community college someday...
    My questions are as follows:
    1) What is the better way for ME to store our photos? Should I be uploading to iPhoto or Aperture? I basically want all of my "master photo images" in the same location in an organized fashion. I am hoping to do this without clogging up my computer. At this point I am thinking at the end of each year I will burn the year's photos to a disk for save keeping. But until then...
    2) Is the "library" the over-arching place where all photos are stored? In general, I am having a hard time following the hierarchy of where my photos are being stored, how to organize them and how to completely delete bad photos.
    3) Can I do everything I can do in iPhoto in Aperture? Obviously I know I can do more but is it as easy to edit/fix up photos?
    I have listened to/watched several tutorials on both programs and have read through many other folks' questions/answers but I am still not sure of what to do.
    I really appreciate any help/advice anyone is willing to give!
    Thanks!

    I'm not a professional either, just a grandma with a love of digital photography who takes lots of photos. We used to live in a motorhome full time, so we had lots of opportunities to take many photos.
    I personally like Aperture better than iPhoto because I like to use some of the NIK software/plugins where I can do the adjusting right in Aperture and don't always have to send the photos to PhotoShop. Also you have a bit more flexibility as to file set ups with Aperture. In iPhoto you don't have as many nesting capabilities. iPhoto is great, but pretty basic.
    I had my photos set up as files on the PC, long before I got my first Mac. So I set them up the same way. I'll try to explain
    In Finder:
    Pictures (in side bar on left in Finder)
    Folder - My Photos
    2nd Folder - by year
    In the year folder I have a folder by date ie: 20000722 (year,month,date) and the photos from that date in there.
    Once I got to using Aperture, I have my years set up as "projects" and the dates set up as "Albums". When importing the whole set of photos into Aperture, it was easy. I highlighted the "library", then did a right mouse click and selected "import folders as projects". That imported the photos into Aperture the same way I have them in finder.
    Once everything is in Aperture, and you have new photos to add, I make an album under the corresponding year and import.
    I do all my photos as referenced and don't duplicate them again, as I have them backed up in a couple of other places.
    IMHO you can't back up enough! Don't wait and do it only once a year! Hard drives have a way of crashing and you'll loose all your photos. Use DVD's, thumb drives, ext. hard drives or what ever works for you. But always back up.
    When I take my photos off of the memory card, I immediately send a copy to the back up external HD. Once the photos are adjusted etc. I make sure I have a copy elsewhere too. Only then do I erase them off of the memory card. Might be a bit redundant, but I'm not about to loose any of my photos. When we lived in the motorhome we were always aware of the possibility of theft or fire. So I got in the habit of taking some time to reduce the size of the photos and keep them on a thumb drive that I kept out of the RV. If anyone broke in or we had a fire, I'd still have the photos. Maybe not the originals or the bigger size, but we wouldn't loose them either.
    If you want more info on non professional filing, send me a PM and I can send you a photo of my file hierarchy . (suemach (at) mac (dot) com)

  • What is the best way for a family to set up apple ID's and icloud?

    My partner and I have separate apple id's and own a mac book, ipad, 2 iphones and apple tv.  What's the best way to set it all up so we can access everything on each device?  Can we merge our ID's into one and transfer all our payments?  We just registered for icloud and used a new shared email address, but still have our separate apple ID's.  We have separate email addresses, calendars and notes that we would prefer to keep separate.  It's really just our itunes purchases, music and photos that we want to be able to share.  Thanks in advance!  Cheers, Nicky

    They will be able to download everything that was bought with their Apple ID. If they all shared an ID then they switched to their own ID they won't be able to use any apps or music bought with another Apple ID. As I explained in my previous response. There is only one way to share apps and content across multiple Apple ID's and that is home share. So, NO there isn't a "Smooth" way to do it.

  • What is the best way for a parent to share/set up an apple id for their children's iPhone if they have an Iphone too?

    So I work for a wireless provider and i often have customers who buy their children iphones. They end up sharing Apple ID's amongst themselves. After they have done this- what is the easiest way to get the content being shared (contacts, pictures, music via icloud) seperated and onto the correct apple id's. Is there a way to get songs purchased on one apple ID duplicated onto another?

  • What is the best way of dealing with an "implicit coercion" of an array to a sprite?

    Hello everyone!
         With continued help from this forum I am getting closer to having a working program. I look forward to being able to help others like myself once I finish learning the AS3 ropes.
         I will briefly explain what I am trying to achieve and then follow it up with my question.
    Background
         I have created a 12 x 9 random number grid that populates each cell with a corresponding image based on each cell's numeric value. I have also created a shuffle button that randomizes the numbers in the grid. The problem I am running into is getting my button-click event to clear the current images off the grid in order to assign new ones (i.e. deleting the display stack objects in order to place news ones in the same locations).
    Question
         My question is this: what is the best way to handle an implicit coercion from an array to a sprite? I have pasted my entire code below so that you can see how the functions are supposed to work together. My trouble apparently lies with not being able to use an array value with a sprite (the sprite represents the actual arrangement of the grid on the display stack while the array starts out as a number than gets assigned an image which should be passed to the sprite).

         Any help with this is greatly appreciated. Thanks!

    Rothrock,
         Thank you for the reply. Let me address a few things here in the hopes of allowing you (and others) to better understand my reasoning for doing things in this manner (admittedly, there is probably a much better/easier approach to what I am trying to accomplish which is one of the things I hope to learn/discover from these posts).
         The elements inside my "imageArray" are all individual graphics that I had imported, changed their type to movie clips using .Sprite as their base class (instead of .MovieClip) and then saved as classes. The reason I did this was because the classes could then be referenced via "getDefinitionByName" by each cell value that was being passed to it. In this grid every number from 1 to 9 appears randomly 12 times each (making the 108 cells which populate the grid). I did not, at the time (nor do I now), know of a better method to implement for making sure that each image appears in the cell that has the corresponding value (i.e. every time a cell has the value of 8 then the custom graphic/class "skin8" will be assigned to it so that the viewer will be able to see a more aesthetically pleasing numerical representation, that is to say a slightly more fancy looking number with a picture behind it). I was advised to store these images in an array so that I could destroy them when I reshuffle the grid in order to make room for the new images (but I probably messed up the instructions).
         If the "drawCell" function only returns a sprite rather than the image array itself, doesn't that mean that my "eraseCells" function won't be able to delete the array's children as their values weren't first returned to the global variable which my erasing function is accessing?
         As for the function name "drawCells," you have to keep in mind that a) my program has been redesigned in stages as I add new functionality/remove old functionality (such as removing text labels and formatting which were originally in this function) and b) that my program is called "Blanko."
         I will try and attach an Illustrator exported JPG file that contains the image I am using as the class "skin7" just to give you an example of what I'm trying to use as labels (although it won't let me insert it here in this post, so I will try it in the next post).
    Thank you for your help!

  • What is the best way to add external C++ code to LabView 6.1?

    I have various C++ class-based DLL's written with Visual Studio 6.0 and wish
    to create instances of these C++ classes and call their methods in LabView
    6.1. What is the best way to do this?
    It seems based on the little reading I have done that there are two choices:
    1. Wrap the C++ class as a simple COM control and use LabView's COM based
    VIs to create a COM object and access the methods of various interfaces.
    2. Wrap the C++ class methods as C functions and a "constructor" and
    "destructor" C function to create and destroy an instance of the class. Then
    use LabView's DLL call support.
    Which is best? What direction is LabView going to take that better supports
    the notion of C++ class libraries?
    Thanks,
    Te

    You could also try using a CIN. This is a tool that LabVIEW provides for interfacing with external code.
    The CINTools libraries of LabVIEW allow you to embed compiled C code into a particular Virtual Instrument (VI) using a CIN.
    In order for LabVIEW to be capable of calling compiled functions of C from a running VI, the code must be loaded and unloaded into memory at the same time as the VI code itself. LabVIEW uses object code in the form of a .lsb file which is generated by the C compiler from the C source code using the ntlvsbm.mak file. This ntlvsbm.mak file is included in the CINtools directory in the LabVIEW folder. You also must create another .mak file which includes parameter definitions for the ntlvsbm.mak file and also includes a call to the LabVIEW .mak file.
    The generic documentation for CINs only explains how to use them to call C compiled code from a LabVIEW VI. It shows several development environments such as Visual C++, but in essence it only allows the user to create .lsb files out of plain C source code ( .c ) through C compilers on those environments.
    The question now is how can I create .lsb files from C++ native source code using a C++ compiler. Furthermore, how can I create a .lsb file from several C++ source code files (.cpp) and make calls to C++ functions from a VI using CINs? The following explains how to do this:
    1) Drop a Code Interface Node (from the Advanced Subpalette of the Functions Palette) into the LabVIEW VI. Make sure to wire the inputs.
    2) Right-click on the CIN and choose "Create.c File...", then in the file dialog box specify a "name.cpp" file name. (very important: use .cpp extension)
    3) Then create a name.mak makefile (text file) and add the following lines :
    name=name_of_cpp_file_without_the_extension
    type=CIN
    cinlibraries=Kernel32.lib
    CINTOOLSDIR=path_to_cintools_directory
    !include <$(CINTOOLSDIR)\ntlvsb.mak>
    4) Go into Visual C++ and File>Open and open the .mak file. You can even Add the name.cpp file to the project to make it easier to edit. Select that name.cpp or open it as a text file in NotePad or and edit the prototypes of the CIN MgErr functions as shown below, adding extern "C" at the beginning of the line. extern "C" CIN MgErr CINRun(float64 *INPUT);3) Select Build.exe to create the "name.lsb" file. To import the .lsb into LabVIEW, right-click on the CIN and choose "Load Code Resource...". Then, choose the name.lsb file and it is ready to run!
    If you want to use several C++ source code files with .cpp extensions, then compile them in Visual C++ and link them to name.cpp and create a .lsb by modifying the name.mak as follows:
    name=name_of_cpp_file_without_the_extension
    otherobj=other_cpp_files_BUT_USING_.obj_extension
    type=CIN
    cinlibraries=Kernel32.lib
    CINTOOLSDIR=path_to_cintools_directory
    !include <$(CINTOOLSDIR)\ntlvsbm.mak>
    It's worth a try? I have also heard of using clusters to represent classes, so you could check that out.

  • What's the best way to detect that text fits into ContainerControllers without scrolling?

    Hi.
    Question
    What's the best way to detect that text typed by user (or added programmatically) exceeds available container space and find out where starts truncated part? Is there available some other (than described bellow) easy way to detect it or disallow set of controllers to receive more characters that can be displayed in given composition area?
    My partialy failed attempt (simplified)
    For example lets say that I've got an editable textflow with attached two instances of ContainerController.
    var flow:TextFlow = createSomeFlowFromGivenString(sampleText),
        firstController = new ContainerController(firstSprite, 100, 30),
        lastController = new ContainerController(secondSprite, 600, 30);
    flow.interactionManager = new EditManager(new UndoManager());
    flow.flowComposer.addController(firstController);
    flow.flowComposer.addController(lastController);
    flow.flowComposer.updateAllControllers();
    With enabled vertical scroll policy I can compare height of the composition in last controller with height of the content:
    var bounds:Rectangle = lastController.getContentBounds(),
        overflow:Boolean =  lastController.compositionHeight < bounds.height;
    trace('Content does not fit into given area?', overflow)
    But when I switch vertical scroll policy off (lastController.verticalScrollPolicy = ScrollPolicy.OFF) - unfortunately this no longer works...(In my case scrolling should be dissabled, since text areas might have only one line with restricted width)
    Use case
    I want to create fillable form. Field might have a single or multiple lines. One field might start in the middle of the page, continue in the next line where it spreads through whole page and end in the - quarter of page width long  - third line. Text typed by the user can't exceed given area since it might cover some static text that sits right after/below field.
    Something like ascii image bellow:
    |                <PAGE>                    |
    |                                          |
    |                                          |
    |                                          |
    |               [Field starts here........ | 
    | ........................................ |
    | ........................................ |
    | Ends here..]                             |
    |                                          |
    |                                          |
    | [Another field] xxxx  xxxx xxxxxxxx x xx |
    | xxxxxxxxxxxxxxxxxxx                      |
    |                                          |
    |                              [One more.. |
    | .....]                                   |
    |                                          |
    |                                          |
    |                                          |
    |                                          |
    |                                          |
    |                                          |
    |                                          |
    |                                          |
    Info:
    [......]  <-- form fields starts with '[' character, and ends with ']'
    xxx       <-- sample, static text
    | and _   <-- page borders

    I've tried something like that previously, but it didn't work because then I've got vertical scroll policy to set to 'auto'. After changing verticalScrollPolicy to ScrollPolicy.OFF  in the last container it worked like a charm.
    Thanks zhen bian

  • What is the right  way to display a table in Java web dynpro using a node.

    Hi experts,
      I am trying to show a node of cardinality 0...n as a table in an adobe form in Java web dynpro. But its not showing it properly. Can anybody please tell me what is the right way to display a table on adobe form using a node of cardinality 0...n or 1...n in Java Webdynpro.  In ABAP webdynpro, we can drag and drop a node of cardianlity 0...n or 1...n to  show as a table and it works fine. Is the same possible in Java webdynpro also. Please help.
    Thanks and Regards.
    Vaibhav Tiwari.

    Please refer to my post.. you will get the answer
    Dynamic Table -  same data repeating in all rows
    Special care should be taken in designing the context for table attribute.
    The attribute type singletone also plays a important role. I have this doubt from the beginning when you have reported this problem for the first time but finally you marked it as solved so i thought there might be some other issues but again when you reported that again i did some analysis.
    Now coming to final solution :
    For designing a table in adobe interactive form you have consider following
    You have to design the view context upto three level, I am explaining you the properties
    PDFDataSource (Parent Level1) - Cardinality 1:1 - Signetone -True - This is assigned to datasource
    TableList (Parent Level2) - Cardinality (1:1) - Signetone -True
    TableWrapper(Parent Level3) - Cardinality (0:n) - Signetone -True
    TableData (Parent Level4) - Cardinality (0:1) - Signetone - false (This is the main point)
    Then under TableData value node, you have to put all your table attributes.
    This Value Node name can be anything but hierarchy should be same as I have mentioned above.
    Please try out these steps and get back to me if you have any doubt.

  • What is the best way to get a time capsule to work with a new network name?

    What is the best way to get a time capsule to work with a new network name?

    Well it seems that you did not explain to us the full story.  Did you change ISP's or something? Why would it not show up anymore?
    What colour is the light on the time-capsule? If it's blinking amber, then you probably need to do a factory-reset. That should get it to show up again in AirPort Utility.

  • What is the best way to merge a file content into log file

    What is the best way to merge a file content into log file.
    In worst case, I will read the file line by line as string, then use
    logger.info(lineString)to output to log file.
    However, is there better way to do this?
    The eventual log file will be something like:
    log message 1
    log message 2
    content from file line 1
    content from file line 2
    content from file line 3
    log message 3
    log message 4Thanks

    Thank you and let me explain:
    1. What do you mean by better?
    I would like to see better performance. read line by line and log each line as string can be slow. Did you measure this and determine that it is actually a problem for your application? Or are you guessing?
    Regardless of what you do you are still going to need to read the file.

    2.The only better way I can think of is not having to do it, but I assume you have a very good reason to want to do this.
    Yes, I have to do it beacuse the requirement is to have that file content be part of logging.
    Any idea?How is it supposed to be part of it? For example which of the following is better?
            File AAA - contents
                       First Line
                       Second Line XXX
            Log 1
                    2009-03-27 DEBUG: Random preceding line
                    2009-03-27 DEBUG: First Line
                    2009-03-27 DEBUG: Second Line XXX
                    2009-03-27 DEBUG: Random following line
            Log 2
                    2009-03-27 DEBUG: Random preceding line
                    2009-03-27 DEBUG: ----- File: AAA -------------
                    First Line
                    Second Line XXX
                    2009-03-27 DEBUG: Random following lineBoth of the above have some advantages and disadvantages.
    The first in a mult-threaded app can end up with intermittent log entries in between lines, so having log lines with thread ids becomes important.
    The first can be created by reading one line at a time and posting one at a time.
    The second can be created by reading the entire file as a single string and then posting using a single log statement.

  • What is the general way to invoke a rpc/encoded webservice?

    Hi,
    I have some confusion in invoking webservices, ok, let me explain my question in detail:
    Usually, we access a web service througt its wsdl file, for a rpc/encoded style, for example, in Axis enviroment, I will need the java object for the complex message types, how can I get these java files? If I use the Sun provided WSDP tool to compile the wsdl file and get these java files, do they work? If I am not in the Axis enviroment, maybe I will compose the SOAP request directly, so, what is the general way?
    Thanks.

    Hello,
    When you want to invoke a Web Services (RPC or Document style) you generally as you said create a set fo Java class to: map the messages information to Java code, and create a proxy/stub to do the call.
    Using Oracle Application Server Web Service framework you have several way of creating this client classes:
    - using Oracle JDeveloper just do a File>New>Web Services>Web Service Proxy
    - using the command line tool, and associated Ant tasks (WSA:Web Service Assembler), see the Web Services Developer Guide
