Re: sms by the nokia
Hello, This posts reminded me of some project I did in the past for our microscope where I send out notifications to users after it has finished scanning on my custom made LabVIEW program. First, you have to select a phone which has "data cable" (a COMx port connectivity)earliest is a 5110 followed by 6110, 6150) the rest uses an IrDA and a modem driver. Each of these phones has AT-Commands set (you can download from ETSI) depending again on the series. Ordinarily you have to send out a "AT+ Command" using VISA or earlier Serial Port VIs or Library and arrange the bytes so that they follow the exact AT commands.This is a tip you could begin with.
Re: magnetic resonance application based on LabVIEW?
Hi, The book of Gary W. Johnson on LabVIEW (mine is 2nd Ed) towards the end of the book is practically physics in content and application perhaps that could give you some insight as it was with my own experience.
Re: I'm looking to track the motion of a particle using imaq
Hello Simy: Well size definitely will be the deciding factor first here (I'm doing laser scanning microscopy) because your choice of vision components will depend on that, thing like resolution is ultimately determined by the smallest "particle" you need to see. That also translates to choosing a camera which can do the job.There could be several combinations of IMAQ Vision VIs/Image processing algorithms to make this work maybe some even have to be customized with codes written Visual C++ or MathLab -- for instance using BLOB (binary large objects) with combinations of Thresholding and even calculations of center of gravity and assigning scores to each to chracterize them. If the particles are on top of each other you have to do a "segmentation" with combination of erosion,dilate etc. to highlight boarders etc. It's gonna be a lot in fact something that cannot be gotten from LabVIEW itself but from other source like books on signal/image processing. Most of it will be a lot of readings about the subject matter of course your ideas could tested initially by creatin scripts from another software package called IMAQ Vision Builder. Good luck!
Re: coordinate system translation from screen coordinates to stage coordinates
Hello Shan: Were almost have the same problem but mine is for a AOI handler with a robot arm which I need to pick (x,y) pairs along the work envelope. Anyway, for the most math part it will involve are coordinate transformation from a "mouse coordinates" to "real world coordinates" and your image processing textbook (I use McGrawHill Computer Graphics by Hill) will outline both the code and the math but LabVIEW will not have a facility to do with an actual VI instead you have to use the array manipulations and treat them coordinates as matrix elements. There is a Math VI and G-Math VI or a MatLAB call you can use for coordinate matrix manipulations as long as you have the math quite figured out in paper already.
Re: problem to connect remote panels
Hello Behzad, I'm no expert but quite experienced with LabIEW features.First, is that running remote panels is possible only for version 6.1 and 7.0.For you to run remote panels successfully (which I did in our lab with five remote panels sharing a motorized microscope) you must see to it both the remote and the local panel have the same LabVIEW versions and each have correct Run Time Engines (which you can download from NI).You may run into network security problems for certain IP address that which network has firewall or required priveleged access (your system administrator can help).Or otherwise if everything seems ok always check of the remote site server is actually there or is down.

Re: multiple images
Hello Luis: Have you tried working on Picture Control VIs? Since custom controls can really just give you a two state output better or flexible toolkits are what you need to fulfill your requirement of animated multisequence action. Another approach is to shoot your valve in sequence using an IMAQ Framegrabber and use IMAQ Vision VIs or have a picture of the valve be taken in sequence on a digital camera save it by JPEG or BMP and design a custom code in LabVIEW using IMAQ vision.
Re: Receiving SMS texts instantly
Helli Mike Newett: If you want this cheap you can use a DAU-9P cable connect to a Nokia 5110/6110/6150 and use the published AT commands for it of course there are better high end models you can use with a MMS and GPRS feature. I have implemented a cheap solution on my lab here to send out notification signals after a microscope scan is done and also send the JPEG images to email addresses. You have to use the older version of serial libraries to hardcode the fone initialization command like AT+CMGF=1 (text mode),AT+CMGS="number" the message. Look for the website by the European ETSI for exact technical specifications of the GSM commands. Altenatively you can use your windows Modem query for valid AT commands and save the log files to a text file. And by the way LabVIEW XP7 has many added features in the TCP/IP function pallete for email and HTML handling.
Re: Integrate IMAQ Vision picture into frontpanel
Hello Felix: First, is that you have to remember that ordinarily LabVIEW does not come with IMAQ or Vision tools as a single package and so you have to learn them separately but ultimately integrate them together in application. There is a set of toolset called "picture control" (early version in LV4.1 to LV5.1?) you can begin from. Assuming you have good grasp of image file types then start downloading NI examples that enables you to read an image, convert them to a matrix form (spreadsheet) and back or into different format. If you have a scanner that can save in TIFF,PNG,BMP or JPEG you could use those files to read them into your routines.
Re: How do I read input data on a TDS 210 using Labview 5.1
Hello, I have the same model of that scope here at the lab.There can be two ways you can do this one is using the Wavestar software from Tek and yes, using LabVIEW. Common to this is the use of a Serial Interface (or GPIB if you wish) that has to be purchased separately from Tektronics, also a null modem and serial cable (DB9) with your version you have to code it using VXI drivers or low level serial VI component library. Read exactly the string command formatting of your Tek manual and send them thru your PC or notebook serial port.
Re: Matrox frame grabber & LabVIEW
Hello,months back I have the problem of triggering an optical signal into Matrox Meteor board II and I am not lucky as you are able to code from the MIL so I resorted to finding a LabVIEW driver for it (unfortunate that the supplier of the board has poor technical support in application programs unlike NI) the IMAQ components I was informed was originally coded by this people in the company called Alliance Vision (France) they have all the Matrox Driver written in LabVIEW. I am interested to see your code in MIL-C if you will permit please send me the source code on my private email, [EMAIL PROTECTED] I work at a physics lab. Berns
