• How to measure the distance using script

  Hello

  Is it possible to measure the distance of any document in photoshop using the measure tool, using the script. Below the steps required by me. Hope I'm clear in my communications.

  I've searched the forums, but couldn't find appropriate answers.

  1. open the Photoshop document

  2. allow the user to draw the line with measure tool

  3. the alert distance

  This only works with CS5 because it now uses the tool instead of a path rule. But it solves all the problems talked about in this thread and many other differences between the original function and the data in the info panel.

  It returns a custom with angle and length properties object if there is a rule tool line in the active document and not of the indefinite. I didn't know if the length must be a unitValue or number in the units of the rule settings. I went with number because the Panel info has different number of decimal places for the different units. And as the Panel assigned the corresponding graduation info per cent the length value is empty

• How can I measure the output of a sensor pwm ultrasound using the module or 9403

  How can I measure the output of a sensor pwm ultrasound using the module or 9403

  Khalil,

  When you say 'measure' the PWM signal, exactly what to tell you?

  You're looking to measure the frequency or cycle of the signal function? You count the edges of the PWM output increase? Looking to control the waveform?

  With reconfigurable FPGA hardware, it is up to the user to define the function of the physical i/o on the FPGA chip. By connecting the signals as Adam suggests your digital pulse will be brought to the cRIO. In your FPGA program, you define the function. You can set a base counter or transfer digital data from single point to welcome you cRIO for floating-point more complex treatment. Example FPGA programs are located in the http://www.ni.com/IPnet.

  Hope this helps, please post any additional questions.

• measure the distance between 2 impulses (PCI-6221)

  Hello

  I have a digital signal that sends a pair of impulses (100ns width each) roughly every 100ms and I measure the time between two pulses of a pair (with a resolution of 100 ns).
  For the moment, I got a card PCI-6221 to accomplish this task. Unfortunately, I have no solution until now only measures of counter, I found measure time between constant frequency signals, i.e. they cannot measure the distance between 2 single pulses.

  Any help / ideas / or even telling me that it is impossible to solve this task are appreciated

  Are the two pulses on the same line?

  If so, you need to just configure a task of the measurement period.  If they are on separate lines, you would use a task of "separation of two-edge.

  You might be to throw off by the timing of it:

  If you do not configure implicit synchronization in your task, will start on the first edge after DAQmx Read is called.  Thus, in order to intercept the signal, that you must configure your task, call DAQmx Read and then start your two squares.

  If you want the task to control the signal continuously, you must configure name timing.  In this case, you will receive a sample on each rising edge of the external signal (assuming that the two impulses on the same line) - If you start the task of counter before starting the production of pulses (which you probably should), then the same samples correspond to the time between pulses, the odd samples would be the time between each series of pulses.

  More information on modes of counting on the 6221 lie in the M series user manual.

  Best regards

• Measure Z to a battery encoder encoder pulse frequency to measure the speed using a 6034 E card

  Hello

  I want to measure the speed of a motor that has an encoder to encoder hung on battery. It provides impulses 3 A, B and Z I uses a PXI 6034 E card. I wanted to know if there are any examples/ideas that could help me with this (I'm new to digital programming in Labview). I moved to NI Daqmx 9.8 recently of the old version that has supported the existing codes and therefore being updated the code. I also want to know if an external clock source is needed to do this. This.

  Hello

  There are several examples in the finder OR example (you can get here by going to help > find examples in a window of LabVIEW). You can browse examples of Encoder on input and output material > DAQmx > entry counter. You should be able to find some examples that will be useful.

  In addition, this link is a good resource to get started using DAQmx: http://www.ni.com/white-paper/5438/en

• To measure the pressure using a pressure transducer that provides the analog current output 4mA-20mA

  I wanted to acquire the current analog signal which varies from 4-20mA using NI 9207. I tried in 2 ways.

  method 1 - created an input channel current analog & used a reading Vi to acquire it. How can I give the channel connections in this...

  method 2 - using NOR-DAQ Assistant, I put the channel connections and I got Amplitude versus time graph. She also gave negative values. Can I do this way which is easier? How can I solve the problem

• How can I change the width of the line that appears when using the distance tool in the toolbar meaasuring

  When I want to measure the distance of a line of architectural drawing and I scroll to the bottom of the toolbar to measure and then I select distance when I measure the distance line is about 24 points. How can I make thinner?

  You should be able to view the properties bar (cmd + E), select the annotation of measure and change the line with setting. If you click on the button 'More', you will be able to select the checkbox 'Use default properties' so any new measure you will have these new settings.

• How to measure the frequency of NOR-DAQmx RPM tasks

  Hello

  I'm trying to measure the frequency using the NI DAQmx task and then convert it to a RPM if possible.

  I have the following material available to me.

  I have a block SCXI-1327 terminal, as well as a 6289 PXI multifunction data acquisition Module SCXI 1126.

  I wired in a mag ai7 sensor on my 1126 and then of the passage of an object metal I get a range of 6-8, so I am able to read the mag sensor.

  What I'm trying to do is somehow convert this analog measurement a RPM using the NI DAQmx task only.

  Any help would be appreciated.

  Hi, smooth,

  Yes, you would select linear, then put in the result of this calculation of the slope.

  The Manual recommends a minimum frequency of at least 15 Hz for setting low range. This card is not really designed to measure the frequency for a single pulse over a long period of time.

  The number of LAPS down (assuming one pulse per turn) that we recommend that you measure with the 1126 is so 900 RPM. If you need measure low revs, and you cannot increase the number of impulses per turn, you could consider either read the signal as an analog waveform, or if it's a digital pulse, using a counter to basic task. In this way, you can use any method you want to handle the situation where there is only a single pulse in a long time.

• How to measure the width of pulse with MyRIO

  Hello

  Sorry in advance if this is not the most appropriate forum.  I'm not entirely sure if it's a more general problem of 'software' or the MyRIO-specific.  I have searched the forums and found a few related topics but could find no one who help me in this context.

  I'm trying to measure the width of a sensor pulse ultrasonic ping.  It emits a signal conditioning - the time that it is high directly corelates how far is the object.  Being new to LabVIEW I am confused as to how do I calculate the time it remains high.

  I read that LabVIEW should not need to 'variables' as in python or C, for what is the best way to measure time, the signal is high?  Normally, I'd go (new_time - old_time), but obviously I can't store an old time in LabVIEW as I would in python or C.

  Other notes:

  I have the sensor correctly ping echoing and I can see the blips on a chart and see a perfectly square wave valid.

  

  To answer your question on how you would in LabVIEW...

  While LabVIEW has not stated/named variables that you have in a language based on text, the data is stored on the wires. You can use the nodes as node registers or shift of feedback to store values between iterations of a loop:

  (this will keep subtracting y (starting with 0) and store the result for the next time it runs)

  LabVIEW also has functions in the range of mathematics/signal processing to make the detection of pulse on a waveform.

• Decrease the opacity of the layer with the Distance from the camera

  Is there a way to automatically decrease layer opacity that layer away a camera?

  We will break down the process of thought, of expression and see if we can make it work for you.

  First of all, you must measure the distance between the camera and the layer. The Expression Language Menu effects has a under vector math method which measures the distance between two points, we can use. Use the camera to a point and the position of the layer on the other and we have the first number.

  Now we must decide what we want the opacity to what concerns the distance. When the layer is the same distance from the camera the zoom value will be called the equivalent of a scale of 100%. It is perhaps a good place to have the layer is completely visible. This distance is easily implemented by assigning the fully visible distance to the Active camera zoom value. Then we have to decide how far the layer must be when it is completely invisible (opacity = 0). Personally, I think that the best way to proceed is to use a multiplier for the zoom value. 4 X with most lens settings is a nice distance.

  To configure the relationship between the distance and the maximum opacity, you can use one of the methods of Interpolation in the Expression Language Menu. We will use the method with the maximum and minimum values.

  We'll put that together in an expression. The two methods to use are

  length (point1, point2)

  linear (t, tMin, tMax, value1, value2)

  Set some variables for each of the values and we're done:

  point1 = thisComp.activeCamera.position;
  point2 = position;
  tMin = thisComp.activeCamera.zoom;
  tMax = tMin * 4;
  value1 = 100;
  value2 = 0;
  
  t = length(point1, point2);
  easeIn(t, tMin, tMax, value1, value2)
  

  If you really want to get fancy then you can add a transformation from layer space to the camera and the layer so that the expression might work even with or without layers relative to the camera and/or the layer. ToWorld changing looks like this:

  point1 = thisComp.activeCamera.toWorld([0,0,0]);
  point2 = thisLayer.toWorld(anchorPoint);
  

  Furthermore, I use usually more descriptive and shorter names for variables, but thought that it would make it easier to understand what was going on in the expression. I use also usually Active camera for my expressions rather than thisComp.layer ("camera 1") because it works little whatever you named your active camera.
