Determine the alternating current

Hi, I have a difficulty to determine the alternating current. I use an op-amp and I am reading the voltage and convert the voltage running with LabVIEW. I can not get consistent results. I was wondering if anyone knew a configuration good op-amp, and then how to convert it in amperes.

Hello

It seems that this topic has been posted on another thread, which can be found here. Other issues/updates should be posted on that thread. Thank you!

  • IPCC Express - determine the age of current contact

    I am looking for a way to determine the age of the current contact during execution of the script. Something like a stage that would match the current age of current contact in a few seconds, then that could be stored in a variable and a value of trigger in an If / then. This could be used to trigger a backup CSQ overflow (if contact is longer than 90 seconds, then route the call to the queue of backup). Normally I use a loop and simply count the number of times that I spend in the loop, but for a specific application, it would be preferable to use the age contact instead. Any suggestions greatly appreciated.

    Thank you

    Check:

    Purpose of report: CSQ ICD

    Field: Current wait time

    Position in queue

    Expected time-out

    Connected resources

    Row identifier: should be your CSQ identifier or string variable

    Statistical variable: Variable that you want to fill in your script.

    As you will see, there are many choices. I think that the current waiting time might be what you want.

  • How determine the crossover frequency

    I'm having a hard time to understand how the high-pass filter determines vs high frequency. What value it measures. ? A change of RGB values or contrast? I see the sharpness of words or blur, but what values determine the amount of blur or sharpening? Is there and the actual frequency being high or is it just a metaphor to compare it to the audio crossover?

    No details on the workings of this filter is appreciated.

    A few additional explanations:

    Audio signals:
    frequency = cycles per second
    It is the frequency in the time domain.
    An arbitrary signal can be represented by a set of harmonic signals (sine, cosine)
    In addition, some DC (direct current, non-periodic component).
    A typical high-pass filter for audio signals:
    The cut-off frequency fc is at the transition between the increase in gain
    (low frequencies) and fixed gain 1.0 (high frequency).
    frequency reduction (mitigation)
    CF 0.01 0.01
    CF 0.10 0.1
    CF 1,00 0.707
    10.0 fc 1.0
    100 CF 1.0

    A typical high-pass filter for digital images:
    frequency = cycles per unit of length or (better) cycles per pixel
    It is the frequency in the space field.
    The highest frequency is 0.5 cycles per pixel (alternation of black and white pixels)
    A line of arbitray in a digital image can be represented by a set of harmonic signals
    In addition, DC-part.
    Each channel that r, G, B is filtered individually, one after the other.
    Frequency and gain are as above.

    A high pass filter applies to mitigation<1 to="" low="" frequency="" signal="">
    and removes the DC component entirely. This would result in a black background.
    Therefore, the background is extended to R = G = B = 128 (8 bits per channel) or
    R = G = B = 0.5 (standard).

    Edges contain stronger high-frequency components. These are preserved.

    http://en.Wikipedia.org/wiki/high-pass_filter

    In this doc, we find a simple implementation:
    y [0]: = x [0]
    for i from 1 to n
    y [i]: = a * y [i-1] + a * (x [i] - x [i-1])
    return y

    x [i] are values of R (or G or B) row in column i in the original image
    y [i] are values of R (or G or B) on the same line in column I after filtering.
    Factor (a) indirectly contains the cutoff frequency.
    This example does not yet apply the SHIFT R = G = B = 128.

    The implementation can be different (filter not recursive instead of recursive, as indicated above,
    higher order instead of first order, using a filter kernel 3 * 3 5 * 5 pixels instead of work
    in each row independently).

    I'm not trying to explain how Photoshop!  There are so many alternatives.

  • Satellite A300-202 - problems with alternating current

    Hello

    I bought a Satellite A300-202 a few months ago and I'm having intermittent problems with alternating current.

    Sometimes I plug the AC power and it does not start (the led are off and windows says that it is on battery) charge. Other times, he is in charge and suddenly stops.

    I suspected it might be the cord broken inside, but it seems to happen also when no one touches it. Usually, when it stops to load, I unplug the wall, wait a few seconds and plug in again, and it starts to load correctly never stop again.

    Someone at - it had a similar problem? I wonder if is it possible to just replace the parts to AC power so I won't have to send the laptop for repair.

    Thank you

    Hello

    I've never had a problem with my Toshiba Chargers but an old non - Toshiba power adapter died after 6 months of use. After the replacement, it works without any problem.

    I think you should check the update of the BIOS as mentioned by Akuma, but for me, it looks more like a problem with the AC adapter.
    So if the BIOS update help t doesn't, the adapter should be checked permanently.

  • VI to determine the name of the project

    For a real-time application, I wanted to determine, at runtime, the name of the project in which the VI has been "content".  I wanted to get the name of the project (even) under four different conditions:

    • on the host, in development mode
    • on the host, in Run-Time mode (i.e. after being built as an executable)
    • on the goal of RT, development mode
    • on the aim of RT, in run mode.

    It is not so easy.  I figured out how to make the first two (use the name property of the active project development and use the next last folder directory of the Application in Run-Time mode mode), but I'm having trouble to get this information to get the target RT code.  Has anyone tried this before?  Did you?  Advice (or even downright Solutions)?

    Bob Schor

    Well, I figured out, but it's not pretty.  In the previous post, I explained why I wanted to do - here I will explain how I did this.

    There are three main modes, under which Applications can run: development mode (when you are programming in LabVIEW and press the button "Run"), Run Time System (an executable on a PC) and Embedded (code that runs on a target in real time, in the form of executable file or development).  Of these, only one mode of development gives you access live (via the Application, the active project property) in the name of the project file.  My goal is to have the user interface and the RT 'chunks' of the project in real time have access on behalf of the project, the system I'll create will use same code on two subsystems, meaning that it will run on the PC at least once in the mode of development .

    The key step is to create a 'constant VI', I'll call CONST name of the project, which consists of a single indicator of string, name of the project, which "held" the name of the project.  I initially thought to use a Global Variable, but there is a technical problem with that I will mention later.  I didn't use CONST name of the project directly, but, instead, use a 'Get the project name' VI that has, for its single release, the name of the project.

    This VI, when it runs, determines the type of request under which it is running.  If it is something other than the Mode of development, he calls CONST project name and returns its value.  If this is the Mode of development, it gets the name of the project, he returned, but just before leaving, he arranges to be updated programmatically CONST project name when it is called in the future, it will return the name of the project (update).  [Then why not simply initialize CONST project name?  I'm looking for a "generic" solution that will always return the correct value, even if I move to another project and don't remember about the change and change - all I have to do to make it work is to run once in the mode of development.  Who has ever developing code without testing before making the executable?].

    I wrote a VI gave the name of project Save, which does the following: he calls set the timer on CONST project name to define the name of the new project (this works even if we put an indicator), calls to use current default to make the new value "stick" and called "Instrument to save" to save the changes.  The problem is that CONST project name cannot be "running" in the State to use current default work without raising an error.  If the name of the Save project is simply called as a Subvi to get a project name, it will be in the State of operation as it is used in the case of non-development mode to get a project name.  The solution to this witch hunt is to use the asynchronous call with-and-Forget 'spawn' name of the Save project.  Finally, we modify register project name so that it starts with a loop "wait", examinging the State of execution of CONST name project and waiting for it to exit the executing State, indicating that it is prudent to make the change.

    Phew!  But it works!  Oddly enough, when I tried this using a Global Variable instead of my Constant VI, I kept getting errors during execution are currently lacking, but despite the mistakes, the code seemed to run correctly.  I found an article (written for LabVIEW 5!) explaining that it was expected as Globals behavior were always in the State of operation.  Actually, I just realized that I had not tried with the call-and-Forget asynchronous schema, then perhaps a decade later, LabVIEW will allow me to do this using a Global without raising an error...

  • How to determine the date of manufacture of computers of HP Desktop

    I support the computers in the House of representatives. Every two years we have elections and some win and some lose. The Freshman Congress Member inherit equipment since the previous Congress however the 'historical' equipment is inherited, not exactly.

    I'm trying to find a way to determine at what age a of each item that they have inherited, and by lifting desktop HP on the site of his number series doesn't seem to tell me if it is still under warranty or not, and when the warranty has expired or will expire.

    The serial number itself contains the campaign of that equipment was manufactured or not? I can't go by the release date "BIOS" because I hope that the BIOS has been the current BIOS because it was purchased and the release date on the BIOS would not date, the PC was built/made/sold. Many that I'm looking start by MXL or 2UA and I figur out if it cannot be translated somehow to a year or somewhere in the middle of the serial number?

    Any help would be appreciated. I have at least 75-125 HP I need to determine the age of... If all goes well, easily.

    Thanks old_geekster, I appreciate your response to my post. I finally locate a guaranteed HP page that allows me to type in the serial numbers of 10 or more and get a report of the beginning of the warranty and end dates. I guess the warranty start date would be coincinde with the date of purchase or close to it, so I'm happy with this info.

    The link you have provided today with computer laptop page wanted to give me the number of the product and serial number and unfortunately the reports that I have to go have that the serial number, make and model, the detailed characteristics of the speed of the processor, the memory installed, current BIOS installed, but no number of product so it is not as useful I fell at last on the page.

    This is a link to what I found and could be useful to others too:

  • What is the quick way to check if the battery current sequency contains nothing or not?

    Hi all

    I have switch from C++ to the labview in a short time before. I got a code written in labview 7 someone else and I am trying to change a code in my labview 2012. In the code, there are a lot of nested structures (like sequency battery, case, etc.). Some code contains 30 batteries but not all subsequences contains controls or code. Someone when I pass in a sequence, it seems empty, but some controls or code could be hiding somewhere beyond the current view. Thus, instead of zoom current sequency block, is that any quick way to identify if the block contains another type or not? Thank you.

    It is spelled "sequence".

    Make sure that autogrow is enabled for the sequence stacked so that you don't have the problem of the code hidden beyond the edges.

    Right-click on the stacked sequence and choose replace with flat sequence.  It will extend things, but how you can see all the pictures.

    Block diagram cleanup allows to get rid of more space and clean up the code.

    If you see empty images, you can right-click on the border between frames and select merge the images.  You should also do this if you have separate frames that should not be because there is already a data dependence that determines the sequence of operation.

Maybe you are looking for
