AKD driver slow for given application

Dear Sir
I am using kollmorgan servomotor and AKD Drive for my inverted pendulum project application. Also I am using Labview softmotion for programming( ni 9514 servo drive). But here the driver is taking the command only after first command is finished execution. For my application the motor has to be continously moved according to the instantaneous command(Angular reading from encoder). Please help me in disabling the existing function in AKD drive or an alternative method to solve this
in the attached word document this problem is demonstrated by doing a program of to and fro motion. i have also attached vi programs that used for balancing inverted pendulum
Thank You

Yes. Here is a link to OWC, one of the best online retailers for Mac upgrades: http://eshop.macsales.com/MyOWC/Upgrades.cfm?sort=pop&model=360&type=Memory
OWC only does Macs and will only sell you the parts that work on your specific machine. The link above shows memory upgrades for your specific model MacBook Pro.
However, the advice you were given above is incorrect. You would be wasting your money if you only bought 4 GB. Older machines upgraded to Yosemite need at least 8 GB. Buy the 8 GB kit from OWC. If you really want good performance, you should purchase an SSD to replace your hard drive. Since you are still using your original hard drive, you can purchase a smaller 240 GB SSD that will give you more space, much faster speed and is still quite inexpensive. The 2.5" hard drives that come with notebooks tend to fail after 2-3 years anyway. You are overdue for a hard drive failure.
I should caution you that there are other parts of your machine that could fail over time. There is a possibility that after upgrading your RAM and hard drive, your logic board could fail. Electrical components wear out over time. Your machine is 6 years old. You should seriously consider a new Mac.

Multiple Hard Drives: one for system & applications, one for backup

I am planning the upgrade of my hard drive setup. Presently, I have only the original 74.53 GB internal drive that came with my June 2004 G5 1.8 dual CPU. I have two goals for the upgrade. First, more hard drive space. Second, a drive for automatic backup. Since I am running OS 10.4.11 and not intending to upgrade to 10.5 at this time for application reasons, I will be using something like Carbon Copy Clone for the backup software (not Time Machine, which requires OS 10.5). My thinking, so far, is to install a 1 TB internal drive for system and another internal or external 1 TB drive for the backup. In perusing the discussions here, it looks like an external drive is always used for the backup. Is this true or would an internal drive work just as well for backup? I want the backup to be as free as possible from any corruption or problems that might arise on the system drive or other computer parts. Does the Firewire or USB connection of an external drive offer a greater amount of freedom from potential corruption as opposed to the direct SATA connection of an internal drive?
I realize that burnt DVD’s offer the greatest amount of freedom from corruption but one doesn’t burn a DVD hourly, daily, weekly or so on. Hopefully, if a problem arises my work underway is residing on the backup drive unaffected. I’m not sure how close in time this can be. I imagine this probably depends on the backup software used and how often the backup is run. I’m not yet fully aware of the options.
For the internal system drive is there any good reason to partition it? I f so, why, and in what way? Do the OS and applications need to reside on the same partition? If not (or better that they don’t), how should a 1 TB drive be partitioned?
Thanks in advance for any suggestions on the best configuration of my hard drive upgrade.

1) The backup drive is best to be external (security from computer failure).
Yes. I am not sure about the "in some ways" my esteemed colleague qualifies.
2) The external backup drive should be connected by Firewire (ability to be bootable & greater speed).
Yes. Just beware that some of the Western Digital models have presented problems. Not the drives themselves but the enclosures. [List of Western Digital bootable and non bootable models|http://discussions.apple.com/message.jspa?messageID=9022456#9022456]
Is a Firewire connected drive any less vulnerable to damage by computer hardware failure than an internal drive?
Yes & no. The yes: I don't know about G5s (they use a different connector from the G4s and earlier with which I am familiar) but in some computers the drives will share the same controller. If the controller goes then all connected drives can be corrupted. The no: Then too, I have had two Firewire drives be corrupted. One was by trying it with a PCI card (not what you're using) that was incompatible with my model computer. The other was when the power source in the enclosure went bad.
This is almost leading me to think that 3 drives would be the best! One internal for OS system & applications (1 TB), one continually connected for auto backup (my original 74 GB), and one (a bootable clone) attached only during occasional backups (2 TB).
The more the better. I usually buy drives in size increments that make sense for my configuration. I have two 120GB internal drives so I bought a 250GB external drive for backup and partitioned it into two so I could just back up one internal to one partition and the second to the other.
I'm perplexed with both your feelings about burnt media. I was not aware of this and fortunately have not experienced problems. However, it is only recently that I gravitated from 700MB CD's to 4.7 GB DVD-RW's for backups. I've been using Maxell
There's backup and there's archiving. Backup is for having a copy of what you're actively using. Archiving is storing stuff that is unlikely to change. Optical media is lousy for backup because files are constantly changing. Backing up a 120 GB onto 4GB media either requires a super organized person or you're spending a day sticking DVDs into your computer.
Optical media is less lousy for archiving, but still not great. Where's the floppy drive on your computer? Where will the DVD drive be in 15 years? It's also a lot faster archiving onto hard drives, and the cost of drives has come down to where the per GB cost is about equivalent of less than high-quality, archival-grade DVDs. Yes, drives change too, but it is also easy to copy from drive to drive. I have items archived on drives that are over 10 years old and as long as I make sure I keep on top of being able to connect those drives to a computer they are usable.
BTW: I tried to quote your messages for this reply, went to "Help" to learn how that is done and found this: "If you want to quote specific text from the original message, click Quote Original to add all the text from the original message to the Message box."

There's a '"' icon in the compose window when you type a reply. If I'm doing a lot of quotes (as I did here) I use that, then edit out the bits I don't want. Otherwise I copy and paste the text and add a > before the line to get it to appear in the special format.

Print driver host for 32bit applications - Stopped working

Hey everyone, when I print to the Adobe PDF Converter print driver it will become unresponsive. It might work for 4 or 5 print jobs and the crash. This happens when printing from Illustrator CS5.5, IE9 and Visio 2010.
What normally happens is I will choose "print" then select "Adobe PDF" as the printer, the print progress bar comes up but not the explorer window where I choose to save the PDF. The Illustrator/IE/Visio crashes.
The only way to be able to print again is to logout and log back in to the machine. I've read some others re-starting the splwow64.exe but I haven't tried that.
I'm running a Windows7 Pro, 64-bit, SP1. Adobe Design Premium CS5.5, Acrobat X Pro. Everything is updated to the latest version.
Any ideas? Adobe?

Print driver host for 32bit application has stopped

Hi.
I'm being asked to troubleshoot an issue with very limited access and I'm hoping that someone can point me in the right direction.
Users are connecting to a WIndows 2008 R2 SP1 server using RDP. They are printing to HP Printers from within the RDP session. The Printers are installed onto the server as TCPIP printers. The error is a crash of SPLWOW64.EXE, and it references the file 'HPZUIWN7.DLL'.
The application they are printing from is 32-bit.
My biggest hurdle is the fact that I am expected to solve the problem, but have limited access to the environment and the people who have the required access are more interested in applying blame for the problem than fixing it (exacerbated by the fact that
if I am right in my diagnoses, they are the cause of the problem in the first place.)
I am of the opinion that the issue is 32/64-bit driver conflict related, but am a bit confused as to the recommended configuration for an environment like this. To summarize my question:
On a 64-bit OS that hosts multiple RDP Sessions (which could be from 32 or 64 bit workstations) that is used primarily for a 32-bit application, should we install the 32-bit print drivers, the 64-bit print drivers or both?
NOTE: I have some .DMP files related to the crash, but as of this stage I'd argue that the troubleshooting hasn't gotten to the point to justify trying to debug those yet.
Thanks for your time.
Dan

I'm not sure why the method is the name that it is. I'm pretty sure MS blocked 16bit app support on 64bit machines.
The failure in the HP UI module is in this method
INVALID_POINTER_READ_c0000005_HPZUIWN7.DLL!CHPCommon::VUpdateResolutionFor16BitApps
They are not checking the memory before using it and it's not a valid pointer and crashes the process.
I'll send this to one of the guys that works for HP but there is not a way for the HP code to get updated like we do with system components. The Office team has a report on this binary and method crashing office applications in 2012, but
it does not look like the issue was every handed off to HP, not that HP could address it then.
The FIRST thing I would do is change the resolution you have configured for the printer just to see if that initializes the data I assume the driver is looking for.
The next thing would be trying a different driver for the device. If you find a newer driver that uses HPZ6RWN7.DLL, it has the same defect.

Error "print driver host for 32bit applications has stopped working"

Got this error when trying to "print" a gmail message to a pdf file. After some research (trial and error) I found that in my case this message is due to the subject line of the message generating an invalid Windows file name. Using the subject line to generate the filename is how GMail decides to generate the file name. I guess this is as good a strategy as any. I cannot think of a better strategy for GMail (would not want that "feature" changed).
Solution: Forwarded message to myself with a subject line that does not generate an invalid Windows file name and then "printed" that forwarded message.
Software: Adobe Acrobat Pro. OS: Win 7 64-bit. Application: Chrome accessing GMail. But I conjecture that this error message is not dependent on the specific configuration I have. For example, I recall having a failure when trying to do "print" a GMail message under 32-bit vista though I do not recall the error message (was very likely different :-). In that case I copied the message into Word and moved on leaving it as a mystery.
Adobe solution (I suppose) is that Acrobat (distiller) needs to check the validity of the Windows file name and give back a rationale error message before passing to the OS.
Hope this helps somone out there.

I am having the exact same problem. I have Windows 7 Pro 64-bit and Design Premium CS 5.5. InDesign is the ONLY program that will not print to any printer. I get the "Printer selection failed." error every time I select any printer, even the Adobe PDF one. I have a Brother printer, an HP Plotter, and even an Oce copier/printer. InDesign gives the error no matter what printer is selected form its own list. Photoshop and Acrobat do not give me any issues, nor does any of the MS Office programs nor Autodesk softwares. It's only InDesign that fails. Reparing doesn't do anything and reinstalling every printer driver is pointless because it's only InDesign that produces the error.
Does anyone know what to do to fix this?

Disc drive icon for downloaded applications doesn't go away

I have downloaded Chrome and Skype for my macbook, and when the applications have downloaded I copy it to my applications like it prompts you to, and delete/eject the disc icons. They go away at first, but once I try to open the new applications the same prompts and disc drives appear on my desktop. Do I have to keep doing this process over and over again? Please help!

DO you OPEN the disc image (.dmg) file and THEN copy the application(s) to your Application folder, or are you simply dragging the .dmg file to your Applications folder?

It is within the table I believe (I'm not a DBA or a developer) since I created a BLOB column and then used the file browse feature to allow users to attach a resume to the table in order to be able to perform a search of the attached documents.
I'm just having a hard time pointing the link in the search results report to the document in the blob column.
The information on that page is great if you're trying to create a link to the document on the initial report.
But I created a query using Oracle Text to run a report that does a boolean search of the attached word documents in the table.
When it displays the search results, it doesn't create a link to the document and I can't figure out how to do it.
Here's a link the the instructions I used to create the initial search report with Oracle Text, mind you I only created the index and query, I didn't add in all the link data since they're using documents on websites and I'm using documents in a table.

Max Hard Drive Size for Airport Extreme 4th Generation (A1354)?

I've got a 4th gen Airport Extreme (A1354) (MC340LL/A).
Currently I'm using a 2TB Western Digital USB2 hard drive connected externally.
I'd like to add a larger capacity hard drive so that I can back up more computers. What's the maximum HD size and configuration I can add to this Airport?
Thanks!
Seth

For now, the nearest available information may not be fully suggestive of
the possible largest or unofficially supported external HDD it may use...
Since a similar-spec Time Capsule has the option for either a 2TB or 3TB
internal HDD as part of that configuration, the safe bet suggests 3TB.
There may be an issue with larger drives and multiple computers using
one large drive, since I'd seen some mention of a few user problems when
two or more Macs were sharing Time Machine storage on one larger HDD.
And someone may know of the information about a software utility that may
be able to help keep track of the files or organize them, in such a situation.
In passing, some weeks ago, I'd read about such a utility to help alleviate an
issue that may result from two or more Macs with Time Machine files on the
same backup hard disk drive. But did not keep the link nor retain those details.
If you did get a larger external hard disk drive of sufficient spin rate RPM
and cache size, then it may be a simple matter to format it with partitions
so extra space may be in reserve or any capacity unable to work with
the total configuration could be used for general storage, apart from TM.
Hopefully there is a good drive available for that application.
I'd inquire of OWC as they have some examples of hardware.
Good luck & happy computing!

Usb-6009 high-speed continuous acquisition for slow control loop application

Hi,
After watching a few Youtube videos, I successfully built a control loop in LabVIEW using my USB-6009. Currently, this loop is limited by the speed my actuator can take and respond to commands, topping out at 200 Hz. This is completely sufficient for my application. My question is more regarding the wasted potential of the USB-6009 to acquire samples at a much higher rate than what would be obtained if I used a simple single sample-on-demand during every iteration of the loop.
It seems to me that having the USB-6009 continuously acquire samples and having my control loop periodically check in for the latest data when it is ready to execute would have the advantage of allowing me to average groups of samples together to lower the overall noise associated with the measurement process (I am reading voltages from an amplified photodiode).
1) Does anyone know how I would instruct the USB-6009 to continuously acquire at say 10 kHz, so that on each loop I will have 50 or so samples that can be averaged together for a more accurate measurement of my control variable? Unfortunately, I'm new to this and not too familiar with DAQmx Timing.vi.
2) I've heard that reading into a buffer can increase latency for moving data into the computer. Given the low speed of my control loop, I don't foresee this as being a problem. Is this a correct assumption? I can probably live with an extra millisecond of latency.
3) I goofed around briefly with DAQmx Timing and managed to see a buffer overflow error. Certain rare events will by necessity cause my control loop to take much longer to execute, so I cannot guarantee that occasionally during normal operation I will not overflow the buffer. Can I suppress this error so that the dialog box does not pop up and the program continues to run uninterrupted? If the buffer overflows and old data gets overwritten it isn't a big deal for me since the control loop is only concerned with the latest data anyway.
Thanks for any info!

Howdy Patrick!

Print driver host for 32 bit applications has stopped working

I just bought a Hp ENVY 7640 printer. I cannot use the wireless printing on my 64 bit computer, with Windows 7. I get an error message "print driver host for 32 bit applications has stopped working". I have looked into all of your online support solutions and nothing I have tried has fixed the problem.

Was there any resolution to this issue? We have a user with the same issue. The details of the error are:

I have a multifunctional Canon i-SENSYS MF4140 and Mac Book Air Mac OS X 10.7.3 Lion (11D50b). I have a problem because I can not scan, it is not driver for this application?

I have a multifunctional Canon i-SENSYS MF4140 and Mac Book Air Mac OS X10.7.3 Lion (11D50b). I have a problem because I can not scan, it is not driver for this application?

I see printer drivers from Canon for that printer for OS X 10.7. but not scanner drivers. If the MF4140 is not recognized by the Image Capture application and Canon technical support cannot offer any assistance, all I can think of to suggest is to try a third-party scan application such as VueScan:

They offer a free trial period so you can see if it works with your Canon.

Adobe Creative Cloud - has anybody had any luck running Adobe CC on a new mac mini? Does it run slow for Photoshop?

Adobe Creative Cloud - has anybody had any luck running Adobe CC on a new mac mini? Does it run slow for Photoshop?

Adobe CC applications are very large and the base Mac mini isn't a good choice because it has only 4GB of RAM and has a slow standard hard drive. To get the most out of ACC you should upgrade the mini to at least 8GB. I'd also choose an SSD or Fusion drive for better performance.

LabVIEW RT driver support for CEI-620?

Hi All,
I am using PXI-8106 to run heavy-duty communication and one chasis holds the CEI-620 card (third party ARINC429 card from GE, formerly Condor Engineering). Currently on the PXI controller only runs LabVIEW RT (Pharlap) since I did not want to install Windows OS to slow the performance. Now here it is the problem, GE does not provide LabVIEW RT driver support for CEI-620 (they do have LabVIEW RT support for CEI-830 though, but that card is PMC interface). Basically right now MAX can not recognize the CEI-620 card on the host side, and I can not deploy my ARINC429 application VI to the target PXI controller. I am wondering anybody here has encountered the same problem and develop the LabVIEW RT driver for CEI-620 on his own?
Thanks.

Hi,
Unfortunately I don't have much more information to offer. I would suggest checking to make sure you have all the correct device information whe you create the ini file. I think you should still be able to develop a driver for a poll based device. It should be easier to generate an ini file if you do not require interrupt information. Make sure you have the correct identification information and try using the VISA Driver Development Wizard again.

What are strengths and weaknesses of the sap.m.Shell and sap.m.App as container for an application wrapper?

My question today: What are strengths and weaknesses of the
sap.m.Shell
and
sap.m.App
as container for an application wrapper?
I currently use non of them, but I see the advantages.
SAP best practise is to use one of them or nest them as shell > app. What are strengths and weaknesses of the approaches?

We prefer to say, the tender mercies of the Fetch block.
You'll notice the "wfm info" cluster as an output of the Fetch
VI. This cluster has gain and offset members- use these to scale
your binary data to floating point voltage representation.
As you point out, the numbers won't be exactly what you expect given
the vertical range and the device resolution. There are a few
reasons for this. First, we don't use the absolute full scale of
the ADC for the maximum input voltage. There are a couple of
codes of headroom at the top and bottom. This allows your input
signal to slightly exceed the specified vertical range without clipping
(you'll get a warning from the driver). Second, these gain and
offset numbers take into account calibration information for your
device. Using these numbers will correct for small deviations
from the ideal offset and gain.
So if you use the gain and offset numbers from the driver, your
measurements will be more accurate than if you assume 0 offset and
perfect gain. They will be most accurate if you make sure to
perform a self-calibration once the device is in your system and at the
temperature that your tests will be run.
