Analog System


Dear Sirs,

I have a two questions when graphing EMG date using your software.

1.  When I produce an EMG graph with a LE, the software produces an iEMG value as a %.  For example, iEMG = 10.9%, or IEMG = 22.0%.  My question is, what does that % represent?

2.  If I produce a graph choosing the "integra"l option, it gives a y-scale of %-S.  What does %-S refer to?

Thank you for any help you can give me.

Sorry for my EMG ignorance!

With Warmest Regards,

1) Consider 2 areas, the first being the area under a curve and the area of a rectangle that has 2 sides along the 2 axes and is just large enough to include the data points. The % being reported is the percentage that the area under the curve is of the rectangle.

 

2) When you select to make a data graph, you have several options for y axis normalization, one of which is "%". When this is selected each data point is presented as the %Max for the data. If you select "%" for y normalization when creating an "Integral" graph you are first "creating" a set of data points that are "%Max" and then integrating them over time. The units are "%-Sec" because the data points have units "%" and we are integrating over time.

 

There are many different graphing options that were added to the software at the request of a number of researchers. They allow one to look at data in many different ways. However, I think it is fair to say that some people will find certain data displays useful and others will not.

 Let me elaborate further on the #2 which is giving you pause. On all of the graphs there is a "Y Normalization" option. If "None" is specified then the vertical units for the data will the original units. However if  "%" is selected for y normalization then each data point value is converted as follows:

    DataNew[i] = 100 * (DataOld[i] /DataMAX) where DataMAX is the max value of the original data

Each DataNew[i] is the %MAX for the ith data point. This becomes the data for the graph. If a regular data graph is being created then the Y-axis units would be % because all of the data points have been converted to %.When making an Integral graph values are being summed over time. So the units for the integral are the units for the data times the time units for the data. Consider this senario with no Y normalization. If you had force plate data in pounds that you were integrating over time in seconds then the result would have units in "Pound-Sec". However if you create an integral graph selecting "%" y normalization then the data points are first converted to %Max resulting in units "%" and then integrated over time in seconds resulting in units "%-Sec".I can't guarantee that making an intergral graph with % y normalization will have meaning but it is an option if you think it does.

COMPUTERBOARDS INSTALLATION INSTRUCTIONS

FOR USING THE PCI-1200/JR WITH

THE ARIEL PERFORMANCE ANALYSIS SYSTEM

January 1999

 

 

 

The PCI-DAS1200 series boards are easy to use.  This quick start procedure will help you setup, install and test your board quickly and easily.  For additional information, see the ComputerBoard web site:  www.computerboards.com.

 

Hardware Installation

 

1.   Shut down and turn off your computer.  Disconnect the power cord and remove the computer cover.

 

2.   Locate vacant slot: Locate any vacant PCI expansion slot and remove the expansion slot screw and cover.  Save the screw for step #4 below.

 

3.   Unpack the PCI-1200/JR card: Caution.  Touch a grounded metal object to discharge any build-up of static electricity before handling the 1200/JR card.  Handle the card by its edges.  If you lay it down, place it on the static-proof bag it is shipped in.

 

4.   Install the ComputerBoards card: Push the 1200/JR card FIRMLY into the PCI slot and replace the PCI slot cover screw.

 

5.   Replace computer cover: Replace the screws that hold the cover in place.

 

6.   Reconnect the power to the back of your computer and start your system.  Windows 95/98 will automatically detect the board as it starts up.

Congratulations!  You have successfully installed and connected the ComputerBoards  A/D card for use with the Ariel Performance Analysis System (APAS) and are ready to use the ARIEL ANALOG program.

 


Hello Moshe,
 
Thank you for your message.  As Gideon has already mentioned, the ComputerBoard company has made some changes to their software that may cause the reported problem with the Analog module.  Several suggestions that we have are:
 
1.  Try using an older version of the Instacal program (the software is on a CD-ROM that was delivered with the original system) and see if the problem still exists.
 
2.  Try upgrading to the current version of the APAS software.  Upgrade instructions are located at the following address:
 
Make certain you follow the instrucstions otherwise the APAS software license may be erased and result in additional charges for a new license.
 
3.  If you still experience troubles, please run the following file:
 
   c:\program files\ariel dynamics\apas\checkck.exe
 
Let us know the Level and which Flags are selected.  Also send the current Site Code for the APAS computer.
 
We look forward to your reply!
 
Sincerely,
 
John Probe

Subject: problem with A to D

 Hi Gideon,

 After solving one problem there is always a new one so we'll never be bored.

 After upgrading a computer and operating system, we installed the original A to D that arrived with a previous version of APAS. I upgraded the drivers from computer board website. The hardware managerrecognizes the board and it seems to work fine. The APAS doesn't see it and we got the following error: CBDIREC not in Environment - O

 What is the solution?

 Thanks

 Moshe

Stan/John-

I have contacted Computerboards regarding the difficulty we encountered a few
weeks ago when you tried to install a system with a board. If my recollection
is correct, there was a problem when we used the new version of the CB setup.
CANA could not execute because the system could not find something or another.
We solved the problem by going back to an older version of theeir Install.

I cannot remember the details and the people at CB drew blanks when I vaguely
described the problem. So I need you to go thru the process of installing a
board on a system with the new CB Install and give me a detailed description
of the problems that develop. Or, should you remember, just pass this info
along to me. It appears that the bulk of our contact regarding this was over
the phone as I have almost no e-mail regarding it.

Thanks, Jeremy


 

Stan & I are both correct on the issue of powering electrodes with the new CES 16 channel board. If the board does NOT have the DC-DC converter installed on the board, there is no on board power for the electrodes and 9v batteries must be used. However if the DC-DC converter is mounted on the board then it can power the electrodes depending on the setting of the jumpers. With CES, the DC-DC is always mounted.

I have installed the PCI analog board in my system & I think I understand the nature of the problems which have been encountered trying to get the PCI version of the boards working.

It basically boils down to this. The board will not work properly if it is sharing an interrupt# with another board. It is easy to check this. Go to Device Manager, highlight "Computer" and click on the properties button. A listing of the interrupt#'s and the boards which use them will appear. Int #9 is where I find my A/D board. If there are other boards listed as using this same interrupt the A/D does not work. If you find another board using this interrupt go to the properties for that board and check the "Disable" checkbox. You do not need to re-boot the computer. The device should become disabled. Now try the Analog program. It should work if all of the sharing boards are so disabled.

I contacted Computerboards about this & they confirmed that the board indeed will not work if there is interrupt sharing. They have a fix in the form of an updated version of CBW32.DLL. Their WEB site is currently down. I will get it as soon as I and check it out and send it off to you if the problem is solved.

Jeremy,

Yes, the interrupt problem is a problem we know about and we do go ahead and try to isolate the board to it's own IRQ.

But we still see a problem that when we first install the board in a new system by itself(video card only other card installed) the APAS analog will not see the board. This board on this computer is on IRQ5.

When I put the board into another slot and try it the program works.(board is still on IRQ5)

I then put the board back in the original slot on IRQ5 and it still works with the analog program.

Not a big problem for us, but it is consistent for the last few systems we put together.

Stan

John-

Clearly a number of the settings are wrong. This is how they should be set.

Board type = CIO-DAS16/330
Base address = 300
Interrupt level =7 *
DMA level = 1
Clock speed = 10 MHz *
# of channels = 16 single ended
operation mode = enhanced
external memory board = not installed *
counter # = 0 source = external *
expansion board = not installed *

Normand-

Since the version you are running is dated 4/27/99 & the latest version
available is from 5/20/99 I suspect that you have software from before the
problem was fixed regarding sampling times.

With regards to the scaling problem with the data I am a bit perplexed. I
tested the function which generates channel conversions for the plates and
all seemed to be working properly. The only thing I can think of is that you
are bypassing the step where the software calculates the channel conversions
[volts to user units] from the various property pages of plate
characteristics. When you select Options/Plates/your plate type and you
click on "Ok", a dialog should appear which asks if you want to have the
software calculate the plate conversion factors. You must answer "YES" to
this.

It would be a help if you could collect a small file of data for me to look
at.

Best, Jeremy

Hi Steve:

  There are many ways of doing it. One of the simple one is to build a pulse generator. It cost around $5 in Radio Shack.  Then you use a switch to light a LED or any light that the camera can see and in the same time send a 1 or 2 volts to one of the A/D channels. This synchronize the camera with a signal on the A/D and if you have EMG on the other channels you can synch them accordingly.

  Another simple method, is to put a large monitor in the background of the video location where the camera can see the monitor. Then use the Oscilloscope function for the EMG and you will see the movement and the monitor in the background with the EMG signal appear on it to synch the two.

  I hope this help

Gideon

Hello Slobodan Jaric,

Thank you for your message.  There are several items that should be checked
to initiate triggering in the analog module.  First, what channel is set as
the trigger channel.  This is labeled in the TrigCh immediately below the
toolbar.  When using the force plate, I usually set this to the FZ channel
as this is the applied force perpendicular to the top surface of the plate.

Secondly, check the trigger level.  This is indicated in the TrigLev field
immediately below the toolbar.  If the trigger level is set too high, the
sample will not be triggered.  Sampling can be initiated using the keyboard
by setting this value to a large negative number (-999 for example).
Ideally, you just need a value smaller than the anticipated signal to use
the keyboard as the trigger.

Also, make certain that the trigger channel in one of the active channels.
The last active channel is indicated in the LastCh entry under the toolbar.
 If for example, the last channel is set to B and the trigger channel is C,
then the sample will not be triggered.

I hope this information is helpful.  Please contact us for any additional
information.

Sincerely,

John Probe

We checked all options (different trig. channels, different trigger values,
different last channals) but the data acquisition was not initiated. I
repeat, according to the InstaCal program, the A/D board works.

Hello Petros Tsintzos and Dr. Christos Papadopoulos,

The Analog hardware/software included in your original APAS computer is based on the DOS operating system. Technology has changed drastically in the last 4 years. The current hardware/software operate from the Windows environment. Unfortunately, the DOS based hardware will not operate in the Windows environment. The Windows system requires new hardware and software.

The same is true for the video hardware. The "new" APAS computers include Digital Video frame grabbers that are not compatible with the "older" analog video frame grabbers. The JVC 9800 is a digital camcorder that takes advantage of the new frame grabber.

If you wish to purchase the current APAS with two JVC 9800, you could use the "new" computer for the video data collection and keep the "old" APAS for collecting analog data. If you wish to collect data on the "new" computer, then you must purchase the analog hardware & software.

I hope this information is helpful.

Sincerely,

John Probe

Dear Mr. Probe Last November I had received your e-mail that propose 3 option for updating our APAS system (its 4 years old in windows 3.1). Now we strongly intereste to buy the APAS software with two JVC 9800 camcorders. We have also the 16 - channel Analog Hardware-software(connect the Kistler force plate and EMGs). How it is possible to work together the new APAS software (that included in the package of $10,000 USD) with the our old analog hardware? Please send me more informations. Thank you in advanced. Best regards Petros Tsintzos isplus@spark.net.gr or Christos Papadopoulos, Ph.D.

Answer 1
========
We do not sell the Analog Module as a "stand-alone" module.  The Basic APAS
is required for complete analog operation.  In order to sample analog data,
one would require the following APAS items.

Basic APAS (Hardware & Software) $10,000
Analog Hardware $7,500
Analog Software $1,500
============================
Total $19,000.00 USD

However, Dr. Ariel has agreed to reduce the price of the Basic APAS to
$7,500 (instead of $10,000) for your circumstances.  This means the total
would be $16,500.00 USD plus shipping charges.


>2. How many channels use this system like analog inputs?
>
Answer 2
========
The standard Analog Module is 16 analog channels.


>3. Which is frequency band of these channels?
>
Answer 3
========
The specs on the Analog module are:
16 Channel Analog Input
Individual BNC and RJ-11 Input Connectors For Each Channel
Input Voltage Ranges: 10V, 5V, 2.5V, 1.25V, 0 to 10V, 5V, 2.5V, 1.25V
Range selection: Software programmable
330 Khz Sample Rate
12 Bit / Channel Data Resolution


>4. What exactly does this software- acquisition, saving of signals,
viewing or
>treatment of signals. What kind of treatments do you have on it?
>I'll be very glad if answer me and if we keep contacts in a future.

Answer 4
=========
The Ariel software provides extensive analysis capabilities including

Ariel Analog Module supports collection of analog data input.  AMTI,
Bertec and Kistler force platforms are supported with an additional
Real-Time COP and VECTORS programs. Force platform software also supports
two plates simultaneously.  EMG analysis software includes Normalization,
Rectification, Power Spectrum, Envelope, Spike, Integral, and Median and
Average frequency.  Data can be output to the printer, ASCII or Lotus/Excel
Worksheet files.

Additionally, you can download and/or view the Ariel Analog Software manual
from the Ariel internet site.  The direct address for viewing is:

Hello Jung, M.K.,
 
Thank you for your message.  The reported problem most likely indicates that the A/D board has not been installed correctly and there is a hardware (IRQ) conflict with other hardware. 
 
1.  Select START, PROGRAMS, COMPUTERBOARDS and then run the INSTACAL program.
2.  Remove ALL boards that are shown by highlighting the board and then select the Remove icon.
3.  Exit the instacal program and then reboot the computer.
4.  Repeat step 1 and run the Instacal program again.  The software should automatically detect the A/D board.
5.  Double-click on the board to set the parameters.  Make certain the board is set fo 16 single-ended channels.
6.  Then select the CALIBRATE icon.
 
You should now be able to sample from the force plate.  If you still experience problems, look at the IRQ's for all the computer hardware and see if anything else is conflicting with the A/D board.
 
Sincerely,
 
John Probe
