Does anyone have information on controling a gas delivery system?

We have a need to control a process gas both pressure and flow. We know that LabView can probably do this. We were wondering if there were any systems already put together?

Have a look at
http://www.bronkhorst.com/
They supply massflow controllers and pressure controllers that can be
controlled by a pc by means of the "Flowbus" (a fieldbus developed by them).
For the Flowbus in turn they can supply a ready to go Labview VI.
On the other hand
http://www.voegtlin.com/
supplies massflow & pressure controllers that are set via the MODBUS
protocol. A free MODBUS VI is available reom NI.
Please understand that this are just 2 suppliers in Europe that i know.
Guess there will be a lot more!

  • Does anyone have a pitch control add-on?

    My wife is dance teacher and is using an iPod to play all the music during her lessons. As in dance it is very usfull to dance and specially exercise at a specific beat, it would be perfect if she could change the beat of the songs while playing using a pitch control.
    Does anyone know of an add-on to do that in the iPod? (I don't what to use an extra tool, e.g. Neumarkt mixer.)
    Thanks for your help! Kuno
    iPod    

    Thanks for your replay and your time.
    But I'm not looking to change the beat outside the iPod. The goal is to have a song in its original beat on the iPod with the possibility to change the beat while the song is playing (like the volume). For a dance teacher that is very usefull if the students exercise new steps the first time: To start you could use a lower beat and after some repetitions you can switch back to the original beat.
    (The work around we are using at the moment, is to change the beat on the computer in tool with pitch control and then load 2 or even more versions of a song to the iPod with different beats.)

  • Does anyone have information about Fieldglass?

    Hi Mills & Mining Community!
    I am looking for use cases for Fieldglass in the Mining industry. I am building a PoV and will appreciate all the help I can get.
    Specifically:
    What are the main differentiators between Fieldglass and Ariba regarding procurement? What can Fieldglass do that Ariba can´t?
    Is there available information about the average ROI in a Fieldglass deployment?
    Which are the business benefits or business outcomes identified in Fieldglass customers? Cost savings? Decrease in permanent workforce? Benefits in compliance?
    I understand that Fieldglass is pretty strong in being a Vendor Management System in Mining so if anyone has further information or knows whom should I reach to get it I will appreciate it very much.
    Thanks in advance!

  • HT201321 Does anyone have information on MacKeeper?

    Both my MacBook Pro and IMac seem to be running really slow...starting up the computer changing applications...pulling things up.  It's just slow.  Is there anything I can do?  This MacKeeper keeps popping up and it says I have a lot of stuff on computer that needs to be cleaned up...don't want to buy if it isn't the problem...Help please

    It is too soon to tell if it is a RAM problem. Adding more RAM might improve your performance, but it will not fix problems. According to your screenshot, everything is running fine. You appear to have only Activity Monitor running. It would be better to run Activity Monitor when your machine is running other applications and exhibiting problems.
    I see many people jump to the RAM conclusion and focus exclusively on that. They miss the real problems that way. Your machine's slowness is a symptom of a problem. It would be better to track down and eliminate the actual problem instead of just making it a little bit better.

  • Does anyone have information on "Mac Keeper"?

    Do any of you know about "Mac Keeper"?

    And thank you for asking about it before downloading and installing...as noted by 71 and VP also, we get a load of questions and issues AFTER it has been installed.  Asking first puts you way ahead of the game.
    Mac OS X machines have so many builtin safety features that one needs to ask first before jumping into some of these things marketed using scare tactics...good luck and keep taking part in ASC...we are one big family of fellow users.

  • HT6041 does anyone have information re: motion 5.1 ? the latest security bulletin describes the need for it but neither  " software update: or the "app store"  seems to have it.

    I have read and re read this security bulletin and I have checked software update and the " app store" and there is no mention of "motion" or "motion 5.1"

    FWIW, here is the Apple troubleshooting note for Motion updates that aren't being offered, and the Apple best practices for Motion and related.   Here are the Mac App Store troubleshooting tips.

  • Does anyone have SSL working with the Sun Java System App Server PE?

    We have been having problems (to say the least) getting SSL to work with the Sun Java Application Server 8.1 Platform Edition.
    We have a signed certificate from VeriSign and have it imported correctly, but when you test it by going to https://localhost:8182/ (note that 8182 is the port set up for SSL) you get a warning mesage saying that the certificate cannot be verified. When you view the certificate you see that it is the one that got automatically generated for you by the app server and not the one we purchased from VeriSign.
    So, I was just wondering if anyone out there has gotten this to work and if so, what document did you follow to tell yoiu how it was done!
    THANK YOU!

    once apon a time i had a real problem with the same issue.. best of luck.. i forget now how to fix.. sorry.

  • I want to change the settings (brightness, contrast, gamma) for my internal cam on Macbook pro. I find having to but a third party software (iglasses, webcam settings) to control basic settings as unnecessary and exploitative. Does anyone have a solution?

    I want to change the settings (brightness, contrast, gamma) for my internal cam on Macbook pro. I find having to but a third party software (iglasses, webcam settings) to control basic settings as unnecessary and exploitative. Does anyone have a solution?

    It is not about payment of $19.95 (Igalsses) or $7.99(webcam settings). This is a very basic setting that should be available in the system settings. The automatic setting of the internal cam does not work great on low lighting as everyone is aware.
    i am just amazed how users take in lying down and suggest solutions such as paying for a 3rd party paid app or improving the lighting in your room.

  • Does anyone have more information on the virus disguised as adobe flashplayer

    Does anyone have more information on the virus disguised as adobe flashplayer that was released last Thursday 5 Apr 12.  Can you simply use time machine to reload the entire system from backup to make sure you don't have the virus.

    On ninemsn TECH news: It's called flashback trojan
    The computer security industry buzzed Thursday with warnings that more than a half-million Macintosh computers may have been infected with a virus targeting Apple machines.
    Flashback Trojan malware tailored to slip past "Mac" defenses is a variation on viruses typically aimed at personal computers (PCs) powered by Microsoft's Windows operating systems.
    The infections, spotted "in the wild" by Finland-based computer security firm F-Secure and then quantified by Russian anti-virus program vendor Dr. Web, come as hackers increasingly take aim at Apple computers.
    "All the stuff the bad guys have learned for doing attacks in the PC world is now starting to transition to the Mac world," McAfee Labs director of threat intelligence Dave Marcus told AFP.
    "Mac has said for a long time that they are not vulnerable to PC malware, which is true; they are vulnerable to Mac malware."
    Dr. Web determined that more than 600,000 Mac computers may be infected with Flashback, which is designed to let hackers steal potentially valuable information such as passwords or financial account numbers.
    Hackers trick Mac users into downloading the virus by disguising it as an update to Adobe Flash video viewing software.
    Apple has long boasted that Windows machines are more prone to hacking than Macs.
    Computer security specialists contend that the reason for the disparity was that since most of the world's computers were powered by Windows, hackers focused on systems that promised the most prey.
    As the popularity of Macs has soared, so has the allure of hacking Apple operating systems, according to Marcus.
    "There has been a significant increase in Mac malware in the last several quarters, so what we've seen with the Flashback Trojan isn't particularly surprising," Marcus said.
    "Cybercriminals will attack any operating system with valuable information, and as the popularity of Macs increase, so will attacks on the Mac platform."
    Computer users, no matter their operating systems of choice, need to protect machines with tactics including up-to-date anti-virus programs and avoiding risky habits such as opening files or clicking links from unknown sources.

  • I've preordered my iPhone 5 from apple and tried to get a sim from o2, they said I couldn't preorder. Does anyone have any information about this?

    I've preordered my iPhone 5 from apple and tried to get a sim from o2, they said I couldn't preorder. Does anyone have any information about this?

    Ethmoid,
    Generally buying on contract or buying outright from apple with a separate sim from a provider is little difference in cost.
    Work out the total cost over 24 months for the phone+monthly tarrif and you will see.
    Also the contracts where the phone is cheapest but have a higher monthly cost tend to be the ones that cost you move over a 24 month period.
    For example;
    Using O2 UK as an example (other carriers are very similar). For the iPhone 5 64GB;
    From Apple £699, plus O2 On & On £20 per month is £1179
    From O2, Phone £249, per month, £41. Total over 24 months is £1,233
    From O2, Phone £169, per month, £46. Total over 24 months is £1,273
    From O2, Phone £69.99, per month, £63. Total over 24 months is £1,581  <Cheapest phone, most expensive
    *These all use the same tarrif of unlimited talk,texts and 1GB data. The only difference is how much you want to pay upfront for the phone*
    Also worth noting is buying the phone from apple and the O2 tarrif is only a 12 month tarrif so you're not locked in for 24 months.
    As you can see, the cheaper the phone, the more the overall amount you pay.

  • NVIDIA control (Shadowplay mostly) with LabVIEW via ActiveX - Does anyone have documentation?

    Hi Everyone,
    I'm looking to capture my monitor video at around 30fps. ShadowPlay works well with my graphics card, and I've found that there is an ActiveX Library on the PC. The attached screenshot shows an example code for 5 seconds of capture. 
    Shadowplay only captures one monitor but I want it to capture both, or make two videos (one for each monitor) preferably. Although a possible work around would be recording one at a time but being able to programatically change between the two. The Shadowplay library is: ShadowPlayServerLib and the NVIDIA Library is: NVI2Lib (I presume this is NVIDIA but could be wrong)
    I can't find any documentation on the activeX commands so I'm struggling to know what inputs and outputs of the property nodes should be. Does anyone have any? A search of the internet brings up my own forum post on NVIDIAs website: 
    https://forums.geforce.com/default/topic/805560/geforce-experience/shadowplay-activex-documentation-...
    Any help on the NVIDIA/ShadowPlay side of things would be great, alternatively any ideas for capturing video at 30fps (I tried to use .NET to capture the screen shots to png files but it only managed 2.5fps without saving them)
    Many thanks

  • Does anyone have opinions about at

         Does anyone have experience with or opinions about the free McAfee security suite offerd by At&t U-Verse? I would also ask the same about OpenDNS, which seemed to work fine on my old Mac. Thanks

    The McAfee product is much worse than useless.
    This is a comment on OpenDNS and other public domain-name system (DNS) services, such as Google DNS. You should use such a service if it solves a problem for you, and not if it creates problems you don't already have. To summarize:
    1. Using public DNS will probably not make your network faster, and may make it slower.
    2. It will probably not stop your browser from being redirected when you try to connect to a valid web address.
    3. It will not make you safer from malware attacks.
    4. It could cause confidential information to be compromised.
    5. It has other privacy implications that you should be aware of.
    A DNS server resolves the human-readable "domain name" of an Internet host, such as www.apple.com, to the numerical address by which that host can be reached. The process is analogous to looking up a phone number by name. There is no chance that changing the DNS server you use will have any effect on a network problem not related to name resolution.
    There are two valid reasons why you might want to use a public DNS service:
    The DNS servers provided by your ISP are misconfigured (perhaps deliberately) or don't perform well.
    You have a use for the filtering controls provided by OpenDNS and others.
    Although some DNS services are touted as responding faster than others, there will be no noticeable difference if your ISP is delivering what you pay for. Most likely, the difference in response time among the DNS servers available to you is on the order of a hundredth of a second or less. But under some conditions, public DNS will significantly slow down network performance. Here is a case in point.
    A content-distribution network (CDN), such as the one used by Apple to deliver software updates and iTunes content, relies on the location of the DNS server to optimize performance. If your query goes to a distant server, you may get slow downloads of Apple content, among other things. From the report of a test carried out by a networking consultant:
    We listed 9 CDNs that would benefit from supporting/using edns-client-subnet, and only two actually support edns-client-subnet: CDN77 and ChinaCache. Others, including Akamai, Internap and CDNetworks, do not currently. This really is too bad, because from the performance data we collected, it is clear these CDNs deliver (much) worse performance currently in many countries to Google DNS and OpenDNS users.   
    Another reason often given for using public DNS is to avoid "redirection," that is, false results from a query for a valid domain name. Ethical ISP's do not intentionally redirect valid DNS queries, though it might happen unintentionally because of a misconfiguration; for example, because the address of a network host has recently changed, or because of a "poisoning" attack on the DNS server. Note that many ISP's may, and OpenDNS certainly will, redirect invalid queries to ad sites, in violation of published standards for DNS.
    Recently, a few low-quality commercial ISP's such as "CenturyLink" have taken to deliberately redirecting DNS queries for some domains, such as search engines. Do not tolerate this practice. If your ISP is doing it, then you should demand that the redirection be stopped, or else switch to another ISP.
    Some ISP's have been said to route all DNS queries to their own name servers, regardless of where the queries were directed—another intolerable practice. I haven't heard that any commercial ISP is now doing this, but if yours is, you won't be able to use a public DNS service, even if you change the network settings on your computer or router.
    Of course, if your Internet access is provided by an employer or institution, rather than by a commercial ISP, then you have to take whatever you get.
    The claims on the OpenDNS website that it blocks malware attacks such as "Flashback" are false advertising. A DNS service does not and cannot block anything. All it can do is to selectively refuse to answer queries. It's trivial for a malware attacker to evade such controls. It's just as easy to evade the parental controls offered by OpenDNS. Nevertheless, you may find those control features useful, despite their limitations. Here is an example of an ASC user who had undesirable results from OpenDNS content filtering.
    There is one limited exception to the rule that OpenDNS and Google DNS don't improve performance. The "prefetching" performed by modern web browsers, including Safari, may confuse some DNS servers, with the effects described in this Apple Support article. The article suggests testing OpenDNS, Google DNS, or another third-party DNS service as a possible way to overcome the problem.
    If you need to switch DNS providers because of a misconfiguration of your ISP's servers, the change will most likely only need to be temporary. The problem may be resolved automatically within a matter of hours.
    If you're considering whether to use public DNS, such as OpenDNS, on a long-term basis, you should take into account the privacy implications. As a user of the free service, you are not an OpenDNS customer, and the service provider—a for-profit corporation—doesn't have a contract with you. The marketers to whom OpenDNS sells access and information are its customers.
    OpenDNS will know, and store, the address of every Internet server you use from now on. This is from its privacy policy:
    When you use our Services, OpenDNS stores certain DNS, IP address and related information about you to improve the quality of our Service, to provide you with Services and for internal business and analysis purposes.
    Concerning personal information, the policy states:
    ...[I]t is disclosed to entities that perform marketing services on our behalf or to other entities with whom we have joint marketing agreements...
    You can't opt out of those disclosures. Read the privacy policy carefully and draw your own conclusions. The privacy policy of Google DNS seems to be somewhat more benign, but again, you should judge for yourself.
    That's not the worst of it, though. The practice of hijacking nonexistent domains followed by most public DNS services could result in leaking confidential information to a hacker:
    For example, consider the "same origin trust model" used for Web cookies. If you're holding a cookie for GOOGLE.COM and you can be fooled into following a link to KJHSDFKJHSKJHMJHER.GOOGLE.COM, and the resulting NXDOMAIN response is remapped into a positive answer to some advertising server, then you're going to send your cookie to that advertising server when you send your HTTP GET request there. Not such a bad thing for a GOOGLE.COM cookie, but a real problem for a BANKOFAMERICA.COM cookie.  
    NXDOMAIN remapping is not something that only happens when you randomly mistype a domain name.  It can be exploited deliberately by malicious links placed on any web page. In the case of OpenDNS, the result would be that a cookie intended for another server would be sent to the OpenDNS web server instead. A rogue OpenDNS employee, or anyone who managed to break into the web server, might then be able to impersonate you on another website. If this scenario seems far-fetched, it's the stuff that network exploits are made of.
    See also a brief, and somewhat outdated, critique of OpenDNS on a Harvard Law School blog, with a response from the company's founder.

  • Does anyone have idea on subscreens in IW21 transaction ?

    Does anyone have idea on subscreens in IW21 transaction ?
    When I go through the available user-extis for IW21 I can see QQMA0008,
    QQMA0010, QQMA0011 and QQMA0012 as the user exit for notification item, cause, task and activity respectively.
    My requirement is to assign user specific data ( pre-structure in Z-table) to these catalog codes instead of selecting directly in iw21(by using F4). Do you think the above mentioned user-exits will help me out in this case?
    Can you please brief idea on how to work on these subscreen user exits ?
    Grateful to your help.
    responses will be rewarded

    Hi,
    Have you tried Transaction Variants in your scenario?
    Transaction variants simplify transaction flow by:
    Inserting default values in fields
    Changing the ready for input status of fields
    Hiding various screen elements and menu functions, or even entire screens
    Adjusting table control settings
    For more information on this pls refer":
