Trigger of gradient

Hello and once more another question:

I would like to have some sort of monitoring degraded. For this, I would like to have some sort of gradient trigger which looks the voltage difference between two points of time.

Maybe something like TTL high when dU/dt is greater than 5V/s so if the voltage drops from 10 v to 5 V in the last second the relaxation should give TTL high, but not if the dropps of voltage from 10.0V to 9.5V within 0.1 seconds and not when the dropps of voltage of 10V to 5V in the last hour. The voltage is variable, and I just want to look for fast voltage dropps / increases.

Thank you very much and goodbye

Hello cj, I have a solution for my problem now.

I use a module of delay time and a module of math for this purpose.

  • MainStage stop drums trigger keyboard

    OK I have an Alesis V61 and MS3. It has 8 pads of the battery. I want to set up a very simple patch where all 61 note keyboard triggers ONLY a piano patch. I want one of the Eb trigger pads (2) - a handclap.

BUT the keyboard also plays samples of Bluebird, which is not good! How to stop the notes on the keyboard trigger the Bluebird Drum Kit samples? Thank you guys

    HA! After 3 hours of tinkering it worked (for me anyway). In the channel strip Inspector, MIDI input set none - kills the keyboard trigger the sample but not the pad... against intuitive but worked for me! Hope this helps someone else

    Hello Kozach75

    This message appears if the RAID controller detects a problem with the HARD drive. On this path, it is not possible to say why this is happening, but there may be a serious hardware problem. Please contact the Service partner and let check the device. G20 is a new unit and the warranty will cover all costs.

  • Toshiba AT10LE-A-108 - strange gradient

    Hello

    I have a model of Tablet Toshiba AT10LE-A-108 and have a strange problem:
    When I see gradient colors, for example, when I run total commander is a gradient from black to grey, the colors are not uniform; There are several horizontal lines up and down the screen.
    Why the picture is not uniform?

    The problem does not appear when in the background is only one color.
    The problem appers in a single game, that I tested, Real Racing 3. When the game starts, there is a gradient of blue screen and is not uniform. Same appearig of horizontal lines from top to bottom.
    Distance between the rows is not the same.

    Thank you.

    Hello

    These gradients are more visible if there is more than different colors used to fill an area and when to begin and breakpoints are further away from each other.
    The gradients are also visible using images with a bit depth of reduced (8-bit or 16-bit) and finally the gradients level depends naturally on the display

  • Z50-75: gradient colors, color banding, dark / dim display (display faulty?)

    I'm having a horrible gradient on my new Z50-75 problem. Everything else seems good, but the quality of the display is terrifying. I'm afraid that this is not an unprecedented case. Is it possible if this Lenovo would sell such a display in 2014? I literally counted the shades of colors. First I thought it was a software problem, I checked all possible settings, gamma, saturation, brightness, bitrate etc. but they all seem fine. They promote this laptop as a multimedia device; screen restores all features multimedia strains. The nuances in the 1080 p movies count? Please tell me it's fixable.

  • How to trigger the dictation from the smart keyboard on the iPad pro.

    I use dictated on my iPhone and my iPad quite often.

    However on my new iPad Pro with the smart keyboard attached, I do not how to trigger the dictation from the keyboard.

    I don't see how to get the soft keyboard back to press the button of the microphone are there, such space suggested by some on this forum.

    This doesn't seem to work in the latest iOS Update 9.

    I would be fine with a hotkey, or have to invoke the keyboard of the shop, then press the button of the microphone, but I don't see how do either.

    When the Emoji button on the keyboard smart strike as the keyboard, the software keyboard emoji is displayed, the space but when I press the soft ABC capital but I cannot get to the regular keyboard with the microphone button.

    A possible alternative would be to use Siri to dictation trigger in recording a memo or another application, space but I didn't understand how to do this job either.

    Has anyone experience this problem and found a solution?

    Unfortunately I had to spend a good hour on the phone with technical support when they finally admit that it was an oversight by Apple.  I hope someone reads this post until they spend countless hours trying to understand something, but has no solution at the moment. Frustrated!

  • 5154 PXI trigger on the external input

  • Electric trigger DAMA IQ & check for new records to collect an infinite number of records

    Hi all

    I have some difficulties with the help of the trigger edge power IQ & questioning the DAMA if it has samples/records ready for pick up.  I have reviewed the documentation on the support to the screw and the examples provided with the driver of the ACCA and have not been able to solve my problem on my own.    What I'm trying to do, is to have this VI capture periodic RF bursts that are larger than a specified threshold.

    I go to this topic in the following way:

    I put the number of samples I captured (finished) for each burst which crosses the threshold
    I put the number of records to capture to be infinite
    I said that the rising slope and the appropriate threshold
    I have then to validate the configuration of the ACCA and start acquiring
    I have then go into a loop and check the backlog of samples as well as the acquisition is
    If either of the above is true then I get the samples with the IQ extract complex WDT vi
    I continue looping until the user stops the vi with a button on the front panel
    I went on this path that I didn't block indefinitely or for long periods of time

    What I see is:

    I'll take one shot and then nothing else
    what the samples never back above zero
    that acquisition is ever complete
    If I switch out the IQ extraction with equivalent IQ reading and ignore the completion back & I get documents like I expect

    My understanding is as follows:

    Electric trigger IQ does not have to be re-armed in VI
    that each trigger to fire IQ Power will create a new record containing the number of samples that I asked

    My questions:

    It seems that when the number of records is infinite that the acquisition is never considered as carried out when the State of the acquisition is verified, is that correct?
    I receive multiple records pending upward on the ASB using this configuration?
    Why a record number is provided with the back of fetch get VI?
    Why would I pick any folder, but the record of zero?
    I'm doing something wrong here?
    Is there a better way to do this?
        
    Thank you
    Russell

    Hi Russell,

    You are on the right track to get your application do what you want. Instead of check to fetch back, I suggest that lets you read the property node DAMA the "' Acquisition > Fetch > Records made" property to know when a new record was acquired. "

    > it seems that when the number of records is infinite that the acquisition is never considered as carried out when the State of the acquisition is verified, is that correct?

    That is right.

    > I get multiple records pending upward on the ASB using this configuration?

    Yes

    > Why a record number is equipped with the rear of fetch get VI?
    > Why would I pick any folder, but the record of zero?

    You ask DAA for an infinite number of records. File 0 started the first trigger seen. Record 1 to the second outbreak (end of disk 0) and so on.

  • Restart waveform immediately start trigger

    I create a waveform 50 ms with an SMU-5451 in SMU-1078 chassis with a controller of SMU-8840 running Labview RT.  The waveform is currently triggered by a pulse of a counter of data acquisition because the timing of the wave must be closely synchronized with data on the acquisition of data collection.  However, this approach is problematic because it is difficult to produce a continuous of the 5451 signal when it is triggered in this way.  If the waveform is exactly 50 ms long, will miss the start trigger.  I can tolerate losing at the end of the wave, but I can't tolerate having a gap in the output, and I need the waveform to start exactly on the edge of outbreak of 50 ms.  I can configure the 5451 to accept a trigger start and restart the wave immediately rather than wait for the current iteration of the waveform to complete?

    I guess I could use a complete the 5451 event to trigger the acquisition of data instead, but I guess there is a way for me to do what I want.

    Are you familiar with the mode "script"? You might be able to use this example script:

    script restartWhenTriggeredScript
    Repeat forever
    generate wfm
    break on scriptTrigger0
    Repeat forever
    generate wfm
    end repeat
    end break
    end repeat
    end of script

    Basically, the idea is that, when it receives a trigger, it stops the execution of the inner loop and finish the iteration of the outer loop. Then it will start again from the beginning and to the inner loop.

    Please let us know if that fixes the problem.
