Bouton reset pour potentiomètre linéaire

Bonjour,
Nous sommes en Terminale SSI, nous devons réaliser un projet (un pont en treillis) pour notre bac.
Notre programme consiste à mesurer la flèche d'un pont (en maquette, balsa et un en PVC) à l'aide d'un potentiomètre linéaire. Le pont (en maquette) ne revient pas forcément à sa position initiale après que l'on ai enlevé des poids.
Le programme marche cependant nous n'arrivons pas à réaliser un bouton reset nous permettant de conserver la valeur de sortie et de réinitialiser la valeur d'entrée tout en sachant que le potentiomètre garde la même tension en fonction de la distance parcourue par la borne mobile.
Merci d'avance pour votre aide
Bonne journée

-Le potard nous permet de mesurer la flèche d'inclinaison d'un pont lorsque l'on pose différents poids dessus. Notre but étant de tester la résistance de plusieurs matériaux.
-Le potard est monté sur une carte d'acquisition NY-DAQ. Celui-ci est accroché au pont.
-La potard est calibrer afin que la valeur de la tension soit comprise entre 0 et 5 Volts.
-Méthodologie de capture: ?
-Algorithme de calcul :
if (t>0&& t<5)
D=t*11,51;
Il est dans une boîte de calcul
Voici le fichier du programme en entier

Premiere Pro CC-MediaEncoder : Reglage de sequence (composite en couleur linéaire) ?

Bonjour, bonjour,
Quelqu'un serait-il me dire à quoi sert cette option ?
Reglage de sequence> composite en couleur linéaire (accéleration GPU ou qualité de rendu max, néccessaire) ??
Je me demande si le fait que mon média encodeur me tape des 6 H d'encodage pour encoder une vidéo de 17mn qui ne comporte pas d'effet ne viendrait pas de là ?
Vu que je ne sais pas à quoi sert cette option.

Hello, hello,
Someone would tell me what is this option?
Setting sequence> composite linear color (or GPU acceleration rendering quality max neccessary)?
I wonder if the fact that my media encoder takes me 6 H encoding to make a video of 17mn which has no effect does not come from there?
Since I do not know what is this option.

Droite d'équation linéaire établie à partie d'une pente et d'un offset

Salut à tous.
Je précise déjà que je suis débutant sous labview et ayant un besoin de programmation, je me retourne vers vous pour avoir éventuellement des réponses mais aussi pour que vous me donniez vos sentiments sur le programme que j'ai réalisé.
Alors, je souhaiterai tracer une droite d'étalonnage (droite d'équation linéaire - y = ax+ b) à partir d'une valeur de pente et d'un offset (ordonnée à l'origine) rentrés par un opérateur. La droite est éventuellement affichée dans un graphe et ce serait pour corriger une mesure de température d'une PT100.
Merci à tous d'avance pour vos réponses et votre contribution.
Zipplie.

Hi Zipplie,
From what I see, I guess your code is working, so that's a good start!
As you are asking for advices, there are many ways to do what you are doing. As you are just doing an addition and a multiplication, I wouldn't use a calculator for that. Express VIs take a lot of space and you can't actually see what you are doing, you need to double click on it. (But they are useful when you are just starting exploring LabVIEW.) I would rather use basic mathematical function and work directly with arrays as the formula is the same for the two values of X. I have linked an example of what you could do (but as I said many solutions are available).
I hope this helps,

Déplacement linéaire

Bonjour,
Je voufrais savoir comment il serait possible de programmer un déplacement linéaire avec le matériel suivant :
Un NI cRIO-9076
Une carte NI 9514
Un driver AKD-P00306-NBAN-0000 (KOLLMORGEN)
Un moteur brushless AKM21E-ANBNC-00 (KOLLMORGEN)
Mon problème est le suivant quand je dois effectuer un déplacement "torque" avec labview pas de soucis mais dès que j'essaye de réaliser un déplacement linéaire le moteur passe en "over speed" j'ai beau diminuer les valeurs dans les boucles rien y fait sa plante toujours.
Merci d'avance pour votre aide.

Hi,

I reset my safari in MAC-Air. Before APPLE site was my home page. How i back apple to my home page, now?

i reset my safari in MAC-Air. Before APPLE site was my home page. How i back apple to my home page, now?

Visit the Apple site you want to be set as Homepage.
Safari > Preferences > General > Homepage:
Apple site should show up and highlighted.
Click the "Set to Current Page" button at the bottom.
Select "New windows open with "Homepage" and
"New tabs open with "Homepage".
Launch Safari, if the Homepage is not opening by default, hold shift key down and launch Safari.

Régression linéaire

Bonjour,
Dans le cadre d'un étalonnage de capteur LVDT, je réalise un programme qui permet à l'utilisateur de rentrer une valeur de déplacement et de récupérer la valeur qu'une centrale d'acquisition lui retourne. Ces données sont réunies dans un tableau puis placées sur un Graphe XY. Existe-il un moyen d'ajouter une courbe de régression linéaire à ce graphe ?
Résolu !

Reset not working on iPad Air. I just bought this iPad Air from an individaual. It was listed as new and came with the box, charger, and guide. The seller said it was jail broken and I told him I did not want it jail broken and he said he would reset

He said he would reset it to factory and I said ok I would purchase it. He supposedly received it as a gift from his business and already had one. Well it all looks in new condition and powers up and down ok, and connected to WIFI when I checked it out at Starbucks. SIRI worked, Safari and the camers worked so I took it. Nothing was on the screen but standard app symbols you see on a new iPad. I compared it to a display at a store.
Well when I got it home I plugged it into my computer and it asked me to trust and I said yes ond on the Air it asked to ok it and I did. Then I tried to go to App store and it came up and asked for the password for a Apple ID. Of course I did not have it. I then tried to do a reset. I went to Settings and did a reset erase everything. It asked me twice if I wanted to reset as it was not recoverable. I said yes. It did not ask for and Apple ID or password. The Air reset started and the Apple logo came up and a bar started to move arcoss under it. It almost became a full bar when the screen went blank and the little small rotating symbol came up. It just kept rotating and never finished. Had to do a hard reset holding the Home and Sleep button for 10 seconds and the the Air came back. Everything is working on the Air except I can not get it to reset and link it up to my computer itunes.
It is on IOS 7.0.4
I hope I am not out my $475. Any help would be appreciated. Any options or suggestions.
Thanks.

You need to return it to the seller and get your money back. You cannot reset or use the device with another AppleID installed unless you know the password for that ID.
If the device has been jailbroken, no one on here can give you any further help...the Terms of Use prohibit us from doing so.

Reset file name and line number in preprocessor

We are using Sun Studio 12u1 on Solaris x86 10u9.
For one of our large projects our make file copies many C++ source files into one large allsource.cpp file. This results in significantly faster compilation and better inter-procedural optimizations.
Unfortunately, when the compiler generates warning or error messages they refer to allsource.cpp. Also when it comes time to debug, dbx is looking for debugging information for the original source file instead of looking for allsource.o.
On Windows (MSVC), we use the #line directive to reset the line number and filename so that the error messages point to the correct line and number, and so that the debugger knows that the debugging information for myfile.cpp is actually in allsource.o.
Does the Sun compiler have anything similar to the #line directive?

To reset the preprocessor to the start of a new file:
#1 "filename"
where filename is the name or complete path name of the file.
To change the line number within the current file:
#N
or
#line N
where N is an integer
Example:
% cat z.cc
struct S { X x; };
#1 "/foo/bar.h"
Int I;
#500
Float F;
#line 1000
Double D;
88% CC -c z.cc
"z.cc", line 1: Error: Type name expected instead of "X".
"/foo/bar.h", line 1: Error: Int is not defined.
"/foo/bar.h", line 500: Error: Float is not defined.
"/foo/bar.h", line 1000: Error: Double is not defined.
4 Error(s) detected.BTW, you might get a similar improvement in compile time by using precompiled headers.
The -xipo option provide inter-procedural optimization across compilation units. Refer to the C++ Users Guide for details.
We seem to have a bug in the Forum software. My original source code and the compiler output have double quotes ("...") but they show as single quotes in the code brackets.

Re: Tree Lines on an Outline Field

Actually, you can use the outline field in Forte R2 to mimic what you're
trying to do. True tree and list-view widgets are fully supported (quite
nicely, btw) in R3.
Basically, set up your subclass of displayNode to have an image data
attribute that is displayed on the widget. Then, create a few stock
tree-like bitmaps (like a vertical line, a vertical line with a horizontal
line, etc.). As the user expands and contracts the nodes in the outline
view, dynamically change the bimtap accordingly.
Hope this helps...

Does anyone know if Forte can put the tree/branch lines on the hierarchical
structure of an outline field? I can get the outline/hierarchical structure
to display and work fine, but without the lines showing how nodes relate,
its hard to read.
Thanks.Wait for Release 3.

Factory Reset without Admin Password, MACbook Air

I have a Macbook air 10.9.4
I want to reset it to the factory settings. I do not know the admin password though. I tried doing to holding down command and R thing, but all that happened was a grey screen came up with a picture of a lock, and a block for a password to be entered in, but I don't have a password.... Please Help!!

It depends on the person, I suppose. But ordinarily Apple is pretty supportive of authorized persons only having access to a laptop's contents when the owner has set a firmware password.
One has to understand that a firmware password's purpose is to protect. It would serve no purpose if anyone could simply ask that the protection be removed. The service to remove the protection is a benefit only afforded to legitimate owners.
The seller should have released his registration the moment it was sold. This permits YOU to then register it to yourself. You should take care of this matter before taking it in.
