scale and LVDT position sensor
Dear comrades:
Hi there;
So, first thing, you should think everything is the conditioning of signals, you will need. The myRIO is an awesome tool, but does not include the conditioning of signals. . You need to load voltage cell and you'll read a resistance value, we must build a wheatstone bridge to do this. Take a look at the following link; Gauges
Regarding the LVDT. they operate on the principle of a transformer and consist of a set of stationary coil and a mobile core. An LVDT measure moving by associating a signal value specific for any given position of the kernel. LVDT signal conditioners generate a sine wave of the main output signal and synchronously to demodulate the secondary output signal. The demodulated output is passed through a low pass filter to eliminate high-frequency ripple. The result is a voltage proportional to the displacement of the base. The sign of the DC voltage indicates if the move is to the left or to the right.
You can enjoy the FPGA chip in your myRIO and use this example
Finally, to save the data to excel, you have several ways to do so; the easiest way is to use the Express VI report, or you can use scripture to table VI.
Hope this info helps
Greetings

Image resizing, I tried to use the scale and positioning, but it won't save!
I'm working on a project and most of the images do not match the size of the screen so I used the video efects > scale and Position to do things. It changes, then I visited and then go back to it and he's back to where he started. I can't understand this?
Even by double clicking on the image and move it with the mouse do not work. It leaves a black line next to the image where it does not. How to cover, I'm doing it wrong? This is how I did in the past. I tried l ' down and restart. Nothing works!
Let me know if you figure out how to fix it you and how you did it.
I thought about it! I went through everything and I mean everything and it was the box that says unifirm scale under video effects. I want that my last 3 hours back Adobe! Thanks for the help though!

EliteBook 840 and GNSS HP sensor
I tried for days to get a solution by satellite, using the store GPS satellites, without a bit of luck.
Sensor GNSS HP and Windows location Services are activated.
The news I just, sometimes, are reading of Altitude, but not natural satellite and no solution.
I tried to put my phone and Tablet next to 840 picks it up and the two satellites and get a quick enough solution. So I know I have gps covering.
AS we know the interface GPS has changed since Win7/XP Win8. WIN8 use an API and not the COM ports.
Has anyone got got a reading, lock / difficulty, HP's GNSS sensor?
@Toffy
I have the latest drivers and bios 1.06.
I downloaded MS sensor Diagnostic tool and I ran in parallel with all the associated GPS apps from MS Store apps do not read correct data in the GNSS-sensor(whitch is a Huawei chip btw). Applications is showing incorrect altitude and missing data.
The diagnosis of Sensort tool shows me as satellites of got16 II in view and 7 satellites used in fix.
These applications show latitude and longitude position, but this info is not the GNSS sensor. According to data of the triangulation of location of Windows Service.
So my conlution is that the GPS apps I have MS Store does a bad job, reading information from the GNSS sensor.
Joint photo shows info of the sensor under test Diagnostic tool.
HP should add a small application with the info on the satellites in view and satellites used in fix, so we don't have to trust these poorly developed apps.

The cable with the NI 9237 Position sensor
Hello
I have a NI 9237 Half/Full-bridge analog input module. Recently, I acquired a position sensor led cable, which is essentially a potentiometer. You can find the schema from the link below or in the attachment.
http://www.celesco.com/_datasheets/SP2.PDF
I realized the NI 9237 requires a half-bridge or full-bridge circuit in the transducer, but apparently the potentiometer is not a bridge circuit, and when I connect the terminals output and excitement to the module, I am not able to measure voltage or resistance. Do you know some way I can use NI 9237 to measure the potentiometer?
Thank you!
larryklee
Unfortunately, if your source is not designed for operation in a bridge circuit, you're probably not use the 9237 to take your measurements. At this point, I would recommend a standard voltage input module. I think you might find this worth reading.

Hello, I designed a vi which contains 5 led is placed at the centre of the façade that occupies the entire screen and 4 corners. However, this vi should be used on different systems, with different screen sizes. But on each screen, I'll need the size of the cover = size of the screen and the light to be placed in centres and corner of this new size of the screen automatically without manual operations and positioning bieng made every time. The option of resizing will perform this task completely or I have to go to some other techniques?
As far as I know, what you want is not easy to do but it's doable but you have to do it programmatically (no adjustment of Labview). Here is an example for only 2 LEDs, but I guess you'll be able to make it work for your other LEDs.
This VI maximizes the front and then positioned the 2 LEDs in the Center and top right on the race. LEDs are positioned according to their own corners left, not on the basis of their centers.

Hello
I played "Mahjong Trails" and in position # 3. He played last night and I just tried a few moments ago and I come in. Can you tell why?
I've struggled since Facebook has said that someone tried to enter in my accouant and they had me off facebook about 3 days. Who would have something to do with it?
Impatient of solve you this problem, because I REALLY don't like this game.
Thanks for taking care of this
hope that I broke all the rules. and I hope that I chose the right forum because I've NEVER done this before.
original title: GAME MAHJONG TRAILS Can t PLAY WHY
Hello Shirley,
This isn't a problem with MSE. You deal with Facebook on this (as hard as I know what to do).
There is an excellent chance that what has happened to your account either interfered with your game or was not completely fixed or there is something else wrong with your account or maybe the game. Your best bet is to start here: http://www.facebook.com/mahjongtrails#! /help/? section = applications_and_websites and see if you can get help any with the game or the other answers predefined or by searching. Then, would be to try general help: http://www.facebook.com/help/?topic=applications_and_websites#! /help/? tab = discussion where you can post questions about your problem. If possible, I try to uninstall and reinstall the game (even if it make you lose your points or your rankings) - or you can ask for help from their first that they are able to help. Or open a new facebook account in the meantime and see if you can download and play the game on this account. So not only will you be able to play, but you will know for sure, this isn't a problem with your computer, the game, your browser or malicious software. You can pretty well and nail down to a problem with the other account or installing the game on this account.
It is almost certainly a problem with Facebook and not your computer, malicious software or your browser. You need to deal with them on this subject. If you have the best technical support coordinated because of your recent problems, by all means to re-open the case, or get help that direct contact is all but impossible here trying.
I'm sorry, we can not help you more, but it's really a matter of Facebook and you need to deal with them to resolve the issue.
Good luck!

How to set up breakpoints with a with a PCI-7344 linear position sensor
Hello
I'm trying to implement an algorithm of scanning for a piezo Nanonics 3D scene, who should synchronize with a card counting (PCI-6602) using breakpoints on the movement card (PCI-7344). The Nanonics Stadium has two position sensors (just for x - y) gives me a linear voltage variable according to the position. Nanonics connected these sensors for the two first entries analog motion motion card connector.
Now I intend to use breakpoints to synchronize the digitization step to a card counting (probably using a RTSI cable), but I got the impression that this can be done by using the entries of each individual axis encoders, no do not using the analog inputs. Could someone comment on that? Explanations or advice would be greatly appreciated, thank you very much.
Kind regards

How to draw and the positioning of images in FieldManager using the method object?
How can I add and the positioning of my images in the position desired in FieldManagers?
I need to add more than 2 fields (HorizontalFieldManager/VerticleFieldManager) in my application and I draw an image using the method of painting ovverided.
NOTE: The image will be established if I do not use mainScreen.add (SeparatorField ()) or mainScreen.add (hori2), see below.
If I use mainScreen.add (mainScreen.add (hori2) SeparatorField ())... n then the horizontalFieldManger won't be empty, drawn in the output screen.
import net.rim.device.api.ui.*; import net.rim.device.api.ui.component.*; import net.rim.device.api.ui.container.*; import net.rim.device.api.system.*; public class BackgroundImage extends UiApplication { private Bitmap backgroundBitmap; private Bitmap fieldBitmap; int width, height; public static void main(String[] args) { BackgroundImage theApp = new BackgroundImage(); theApp.enterEventDispatcher(); } HorizontalFieldManager hori2; public BackgroundImage() { //The background image. backgroundBitmap = Bitmap.getBitmapResource("jalan_logo.png"); MainScreen mainScreen = new MainScreen(); hori2 = new HorizontalFieldManager(); HorizontalFieldManager horizontalFieldManager = new HorizontalFieldManager(HorizontalFieldManager.USE_ALL_WIDTH | HorizontalFieldManager.USE_ALL_HEIGHT){ //Override the paint method to draw the background image. public void paint(Graphics graphics) { System.out.println("come to here..!!"); width = graphics.getScreenWidth(); height = graphics.getScreenHeight(); //Draw the background image and then call paint. graphics.drawBitmap(width/2, height/2, 150, 40, backgroundBitmap, 0, 0); super.paint(graphics); } }; //The LabelField will show up through the transparent image. LabelField labelField = new LabelField("This is a label"); //Add the manager to the screen. mainScreen.add(horizontalFieldManager); mainScreen.add(new SeparatorField()); mainScreen.add(hori2); hori2.add(labelField); //Push the screen. pushScreen(mainScreen); } }
Help, please.
I have already pointed out the problem with USE_ALL_HEIGHT in first Manager add you to the form. Drop this style bit, otherwise sublayout your screen will generate an exception, and nothing appears!
If you want HorizontalFieldManager to be of a particular size, regardless of the height of managed fields, replace its sublayout:
HorizontalFieldManager fieldManagerTopBanner = new HorizontalFieldManager() { protected void sublayout(int maxWidth, int maxHeight) { super.sublayout(maxWidth, maxHeight); int myDesiredHeight =
; setExtent(getWidth(), Math.min(myDesiredHeight, maxHeight)); } protected void paint(Graphics g) { // g.setBackgroundColor(0x000000);//blue g.drawBitmap(100, 150, 100, 200, jlnLogoImg, 0, 0); //g.clear(); super.paint(g); } }; -
communication between master blocking and blocking fowarding sensor sensor
1. how the communication between the master sensor blocking and blocking fowarding sensor take place?
RDEP or SSL or SSH? Which one?
Forwarding of blocking sensors will use RDEP more 443 (https) to communicate with the master blocking sensor.
To ensure that the sensor of blocking of the Master to allow connections from sensors transfer blocking under the hosts permitted configuration section.

Hi all
Very green, when it comes to ADF so I hope to give you enough information to get assistance.
I found a 2008 document that created Frank Nimphius that shows how the JavaScript in the ADF and the manipulation of the inline style property.
It is titled "ADF Code corner 010. How to create a character counter of entry for text fields.
While my use case is not the same I feel that I could use for my use case logic.
My use case is that the user wants a text field to replace the blue color when being typed in so that they know what they changed.
I'm jusing JDeveloper 12.1.2
That's what I have my input text looks like:
<af:column sortProperty="#{bindings.ChiefScaleOrderVO.hints.OrderNo.name}" filterable="true" sortable="true" headerText="#{bindings.ChiefScaleOrderVO.hints.OrderNo.label}" id="c1" width="11%" inlineStyle="#{recordManager.columnStyle}"> <af:inputText value="#{row.bindings.OrderNo.inputValue}" label="#{bindings.ChiefScaleOrderVO.hints.OrderNo.label}" columns="#{bindings.ChiefScaleOrderVO.hints.OrderNo.displayWidth}" maximumLength="#{bindings.ChiefScaleOrderVO.hints.OrderNo.precision}" shortDesc="#{bindings.ChiefScaleOrderVO.hints.OrderNo.tooltip}" id="it1" autoSubmit="true" valueChangeListener="#{recordManager.columnTextModified}" clientComponent="true"> <af:clientListener method="keyInput" type="keyPress"/> <f:validator binding="#{row.bindings.OrderNo.validator}"/> </af:inputText> </af:column>
This is what looks like my javascript:
<af:resource type="javascript"> function keyInput(evt){ //document.getElementById(evt.getSource().getClientId() + '::content').style.color = 'blue'; textfield = evt.getCurrentTarget(); textfield.setInlineStyleProperty("color","blue"); } </af:resource>
If I do an alert (textfield.getInlineStyleProperty("color")); before and after the the setInlineStyleProperty it does not say it gets the value at the blue, but my text color never changes.
If I do the document.getElementById (evt.getSource () .getClientId () + ': content ""). style.color = "blue"; It works, but I'm doing things the "right way".
So is there another way to do this now in 12 JDeveloper?
Also is there anyway to when you click inside an af:inputText that he will not select all of the text and just position the cursor at the end?
Thank you
Derek Hansen
Well, you try to set the wrong property.
According to your example of "pure" javascript, you must set contentStyle and not inlineStyle.
Then try something like: textfield.setContentStyle ("color: Blue");

Find anchored objects (reference point and exposed position) script
Hi all
is there anyway to find anchored (reference point and exposed position) of inDesign objects and overthrow their attributes or change them in all the documents, I opened, but by the script because sometimes when I try to do that find and replace option files crash or replacement process does not receive all wanted items
ex:
I want to find objects anchored with below attributes
and change them to:
Thanks to all in advance
Hello
Try this code to find and change,
myDocument var = app.activeDocument;
app.findObjectPreferences = NothingEnum.nothing;
app.changeObjectPreferences = NothingEnum.nothing;
app.findObjectPreferences.anchoredPosition = AnchorPosition.ANCHORED;
app.findObjectPreferences.anchorPoint = AnchorPoint.CENTER_ANCHOR;
app.findObjectPreferences.positionReferencePoint = AnchorPoint.RIGHT_CENTER_ANCHOR;
app.changeObjectPreferences.anchoredPosition = AnchorPosition.ANCHORED;
app.changeObjectPreferences.anchorPoint = AnchorPoint.CENTER_ANCHOR;

Impression of the scale and line thickness
I need to print a Wallcovering that will be about 17 m long. I've created several images more small (about 4 m square) and they have narrowed it down so I could make a plan for how they will join together to create a single image. But I'm unable to identify ways to print at the right scale. My plan is to do the last piece that I send to the printer at the 10% level and then ask the printer to print to 1000% - which would be correct? In addition, the thickness of the line drawings in the 4 m, those are the right size I wish they were, but by reducing my images - the thickness of the line remains the same. How to do this? What is the best way to expand all?
Thank you very much
If the thickness of the line remains the same and you want to scale, double-click on the scale tool and turn on the features of the scale and effects, before scaling.
Yes, 1000% woful be correct for a 10 x scaling.

Scale and move a finshed animation
How can I scale and move a finished animation (with several object - should I consolidate them or something since I didn't wan't to touch the bottom?) without having to do it on each keyframe? I'm completely new flash a detailed response would be appreciated.
You must take the time to familiarize themselves with the tool you are trying to use the option - the forums are no place for lessons, mainly aid just for the problems that you can demonstrate.
To create an empty movieclip, in the main toolbar (the Explorer for awhile) choose Insert-> new symbol-> (new sign symbol) MovieClip-> OK
