Position sensor with accelerometer

Hi,
Recently, I have finished a project with accelerometer to detect the noise when the motor stroke hit some part or near by mechanical part. I wonder about using position sensor to my project in order to detect the stroke or mechanical part position when it hit by stroke. I don't know that I can go along with position sensor to detect the noise or any support for accelerometer. Can any one experienced this kind of situation. Any ideas will be appreciated.

velocity has positive and negative direction. Since you are forcing your negative velocity (direction) to zero, the integration to displacement assumes you always are traveling in the same direction. In other words, you never go back.
Let you velocity measurements and integration have both positive and negative results, your displacement will return to 0
Hope this helps.

Setting up DAQ system for testing (using pressure transducer, linear position sensor and strain gauges)

Hello,
I like to get your suggestion in setting up the DAQ system. I am very beginner in this issue.
These SCXI listed below are what we have in the laboratory. I will use DAQ card 6062E.
SCXI 1000
SCXI 1520
SCXI 1140
SCXI 1142
SCXI 1305 , 1302 , 1300
SCXI 1122
SCXI 1100
I will use linear position sensor in my experiment. But I'm not sure which SCXI shoud I connect to this sensor.
This sensor gives 4-20mA output. it requires +13 to +28Vdc excitation.
I will use pressure transducer (strain gauge type) which gives 100mV output and requires 10Vdc supply.
I will use strain gauges 350 ohm.
Regarding to the number of channels used in my experiment, I will use 1 channel of pressure transducer, 1 channel of linear position sensor and 3 or 4 strain gauges.
Could you please suggest me which SCXI should be used with pressure transducer, linear position sensor and strain gauges.
Now I'm thinking to use SCXI 1520 with strain gauges and pressure transducer. Is that ok?
But I'm not so sure on the linear position sensor which gives current output.
And regarding to sampling rate, I like to get minimum of 60-70 KS/s for pressure transducer. And around 1KS/s for linear position sensor and 1KS/s for each channel of strain gauge are enough. Can I archieve these sampling rate from the available SCXI modules mentioned before? I attached the datasheet of pressure transducer and linear position sensor for you. Please see attached files.
I'm reallly look forward for your suggestion.
Thank you in advance,
Ganchai.

Hi Ganchai,
I would recommend the 1520 with a 1314 terminal block for connecting your pressure transducer and strain gauge. It is designed for excitation, bridge completion and has many other features to fit these applications. For your linear position sensor, try using the 1100 module with an additional precision shunt resistor. For example, our 1308 terminal block has built in 249Ohm shunt resistors for taking current inputs for your 1100. These connections should give you the readings you would like.
As far as sampling rate goes, you should be fine with your requirements. Good luck and I hope you are succesful.

Can you use nike+ sensor with iPhone 5

can you use nike+ sensor with iPhone 5. like the device you place in your shoe. Can it be connected to your phone.

However, you don't need the sensor if you use the Nike+ Running app. It uses the phone's built in accelerometer.

Can I use the same nike+ sensor with two differet Ipods and register the trainings in onmly one account?

Hello, I would like to know if I can use the same nike Ipod sensor with two different ipods. I want to use the same sensor sometims with an Ipod touch and sometimes with an Ipod Nano, I want my trainings with both Ipods to be registered to the same account. I want them to be registered to only one account, not as it had been used by two different people.

Of course. You should use the same AppleID on all your devices. Why would you create a new one?

My positive experience with FCPX.

In an effort to present the other side of the coin on this forum, that FCPX can work very well, here is my story.
For the last 8 years I've been using Final Cut Express on an older Macs. It worked fine for my various projects, although the incessant rendering would be very frustrating. (I never did find the proper format to prevent it.) When Final Cut Pro X was released, I read about it's shortcomings, so I passed.
Five months ago I was planning to video my nephew's wedding so I looked closely at Final Cut Pro X, but was very daunted by how completely different it was from FCE. A few days later I was in my local Apple Store asking their video expert about the rendering in FCE, basically he said to get FCPX, which not only handles many formats, but renders in the background when needed, and has a lot more features than FCE.
I went home and looked at my first FCPX tutorial online and thought, OK, it looks like I'm going to have to start from scratch to learn it. My MacBook Pro was going on 6 years old, so I also decided to buy a new one that could handle FCPX. I had to stay on Snow Leopard OS 10.6.8 for one vitally important application that was not being upgraded, so I went to the Apple refurb site and found a 17" 2.2Ghz i7 late 2011 that fit the bill (I wanted the ExpressCard slot), marked down from $2600 to $1900, I grabbed it.
I immediately installed 16 GB of RAM, and replaced the internal drive with the one in my old laptop, a fairly new Seagate XT Hybrid 750 GB/16 GB HD/SSD. I then bought FCPX. (After completing one small project, I actually replaced the 750 hybrid with an OWC 960 GB dual platter RAID 0 internal SSD, wow, is it fast. I work my current project there, then when complete, move it to the 750 hybrid or a 3 TB I put in a Seagate GoFlex Thunderbolt adapter .)
I have to admit that it took me a couple of days to let go of FCE and get used to the FCPX Events/Projects system, but I got through it. I did look at tutorials, but actually learned far more by exploring the menus, panes and icons, experimenting, trial and error, and reading this forum.
I finished the wedding video (32 minutes long) in about a week (learning as I went). It was shot with one camera, which forced me to do some creative editing by lifting, moving and zooming various pieces (and cutting around a very oblivious professional photographer), which gave me a multi-camera look. I added a title, transitions, adjusted dark scenes, leveled the audio in many places, diminished airplane and wind noise, and dropped in a sound effect of my nephew breaking a glass under foot (which did not actually break at the time).
I shared the wedding video to my AppleTV2, and to DVD (3 copies), and to YouTube, without any overt problems. Yes, each operation had it's learning curve, but I accomplished them all in a rather short time. The first time I uploaded it to YouTube, it took about 8 hours for a 1080 2.8 GB version, but when it was done, the YouTube site had a message that it was too long, I had to register to have longer than 15 minute videos. I then used FCPX to upload a 720 version (the actual original format), 985MB, which took about 2 hours (even with a 1 mbps upload internet service). It looks great via the YouTube app on my AppleTV2.
The only overt problem I have is a crash once in awhile either at launch or very shortly after, but I delete the prefs and continue on. I also installed some free plugins that seemed to cause some crashing, so I removed them, but the next time I opened the wedding project, I had all kinds of warning triangles. Turned out I used some of the plugins and FCPX warned that they were missing. It took a few minutes of searching this forum to learn how to get rid of those effects, I didn't even have to ask anyone.
I just bought two new 1080p AVCHD video cameras and really look forward to using them for a festival on Sunday where I'm playing with a ukulele orchestra (which I also took up a few months ago). I'm going to tackle the multicam operations with that project (something I did in my own way with FCE, even though it did not actually have that function).
My view of many of the posts on this forum is that either they have a system/hardware problem outside of FCPX, or they do not make enough of an effort to learn and understand FCPX. It takes diligence and patience, which in my experience, really does pay off. I used to dread doing tweaks in FCE, now I look forward to it in FCPX.

I'd just like to add my positive-ness with FCPX! I've used it from 10.0.1 and, since 0.3, I have loved it and raved about it when anyone asks. The multicam feature is amazing! I used to use Vegas MS for some casual editing and the biggest annoyance with FCPX at the start was the magnetic timeline but after a day or so I got used to it and now can't imagine using anything else. I've had the odd crash but they are few and far between. I won't say I haven't sworn at it a few times but the fault is usually mine in the end!
I use an upgraded 2012 MacBook Pro with 16GB memory and a Seagate Hybrid XT disc for my more "beefy" projects but I've found my 2011 MacBook Air works great with smaller projects (4GB RAM and 256GB SSD). Interesting article on fcp.co about MBAs and FCPX if anyone is considering purchasing one.
I tend to learn things as I go along; I know what I want to achieve and then work out how to get there, often with the help of the nice people in this forum . With FCPX, once you understand the basic structure it's not too difficult.
It seems one of the common themes is problems with importing AVCHD / MTS files. Since 0.3 I've never had any problems as long as I follow my basic rules -
Format the SD card in the camera just before use (use "low level" if offered for the first format) and shoot your footage. Use the same quality format on that card throughout the shoot.
Remove the card and plug it into the computer's card reader. Do NOT interfere with or modify the files in Finder in any way!
In FCPX create an archive from the card on a separate external disc. (If the card doesn't show up then try another card reader - there can be differences in USB chipset implementations).
Import to the events from the archive. Once done, repeat from 1.

Region position 2 with 2 parts.

hello
My pages are made like this :
Menu region in region position 01
Body pages in region position 02
Now, in the body pages : there is some pages in witch the content ca be organized in two parts (in each part I can have a report).
I know that I can not have a region within another region...
How can I manage this type of pages/regions.
thanks!
Marie.

Use 2 or more regions in Display Point Region Position 02, with different region templates as necessary to display titles, buttons etc.
e.g. Region with items at sequence 10; region with report at sequence 20, using region template Region without Title or No Region so it appears seamless with the first region.

Inductive proximity sensor with DAQ

Hi everyone
I am planing to connect my inductive proximity sensor with NI-9215 DAQ but not sure will that thing work perofectly. Also i don't know how to connect my sensor with the BNC terminal.
The sensor I am using is from automation direct AM9-05-1A with input volatage of 10-30 VDC and output voltage range from 0-5 VDC.
I want DAQ to monitor my output signal from sensor.

Hey lynn
I am planing to use NI-9215 DAQ. Here is the link for that.
http://sine.ni.com/nips/cds/view/p/lang/en/nid/208793.
Since this kind of DAQ has BNC type of connectivity with it so I am not sure how to connect my sensor with this connector.

Internal error in FORM/FUNCTION CKMC_REVALUATE_ENDING_STOCK in position 1 with RC

Hello SAP Gurus,
I am getting this error while trying to close a material in Material Ledger Cockpit
Internal error in FORM/FUNCTION CKMC_REVALUATE_ENDING_STOCK in position 1 with RC
Message no. C+099
Procedure
Please inform your system administrator.
CKMC reports no inconsistency.
Does anyone have any suggestion?
Cheers,
TD

Shipa,
Thanks for your suggestions. Thanks for taking the time to help.
I was able to resolve these issues using the following steps in our sandbox/test environments. I have also included other problems I faced in material ledger month end closing steps for the benefit of readers.
**** Caution: Do not do the following steps in production environment. You will destroy your production data irretrievably. Material Ledger is unforgiving!!! ***
1. For the materials with "Internal Error in Form/Function etc issue, I performed a CKMM in the respective plants changing for 3S to 2S and then did the same in reverse (2S to 3S). Then ran the ML close. This seems to have temporarily solved the problem.
2. I was also getting a short dump -- either during MMPV or during period close in the cockpit. The message at both times was "Error in MLCCS ...". I realized it related to Cost Component Split. I identified the company codes of the materials that caused the errors, then got all the plants within each of these company codes. I ran MLCCS_RESET and then MLCCS_Startup in SE38. Then ran MMPV/ML Close. This seems to have resolved the issues at least temporarily.
3. Occasionally I noticed some "material valuation is inconsistent in valuation area xxxx" error. I executed steps 1 and 2 above in succession. This seems to have resolved the issue temporarily.
4. There was also the issue of "duplicate entry in CKMLKEV" while performing Single/Multi-Level steps in the closing cockpit. This pointed to MLCCS. So I ran step 2 above. Again this seems to have fixed the issue temporarily.
I was able to accomplish all of these using the steps above because these were in our test environments. The reasons as to why these happened are manifold:
MMPV was not carried out for a long, long, long time in certain plants within a company code. When ML is active, it is necessary to close previous period. In cases where MMPV was not carried out for a long time, I ran CKMHELP program to set the material status to 70 for the immediately preceding posting period. This helped run the ML cockpit for the current/previous periods.
Users were processing too many transactions with unrealistically large quantities and prices resulting in overflow errors. I carried out reversal of movements for each process category to reduce the inventory balances to reasonable quantities, and ran MR21 to set the prices correctly. This helped resolve the overflow issue.
Reckless, repeated running of CKMM and MLCCS_Reset/MLCCS_Startup also contributed to these problems. Every time a standard had to be released, but the material status in ML is "30-Quantities and Values entered", would prevent users from doing that. So they resort to CKMM and then reset status using CKMHELP program to set the status to 10 and then release the new cost. It works, but wreaks havoc on ML as a whole eventually.
Hope my comments are useful for some!!!
Cheers,
TD

Internal error in FORM/FUNCTION CKMLKEPH_ROLLUP in position 2 with RC 4

The order settlement terminates with the error Message no. MLCCS 099 "Internal error in FORM/FUNCTION CKMLKEPH_ROLLUP in position 2 with RC 4".
The material ledger is active. The actual cost component split is active. I want to carry out the order settlement for one plants.
With the same production material no.in the plant. There are many other productin order are settled in thid period. But, only one production order got the error message, why?
I knew that I could change the Price determ. (in material master) from 3 Single-/multi-level to 2 Activity-related, then I can continute settlement transaction in CO88. But , I want to know what's wrong this the order. What should I check about the order. Why other orders are settled without error with the same material no, and plant.
I had check about SAP note 711416 & 729901 & 523100 & 623701 & 653523, those can't slove my problem in CO88.

Thanks for your answer.
But, I have two production orders product the same material in the same plant and will be settled in this period. Both of those two orders were consumed material in 3 months ago. But, only one of them were terminated with error message in CO88. Why? How can I find out the difference between those two orders? They seems the same.
For SAP note 623701 & 871926 & 867755, I think we already implemented those. I had found program "MLCCS_KO88_TREATMENT " in SE38. And, I can find the message 013 & 015 in message class MLCCS. So, do you have other commendations?
Do you know how could I check about "Display order history" that mentioned in note 86775. Which T-code should I go to?
Thanks a lot.

Internal error in LMLCCS_UPDATEF02 LCL_DB method get_normvector position A with RC 1 when VL31N processing only

HI Everyone,
I have mentioned error (Internal error in LMLCCS_UPDATEF02 LCL_DB method get_normvector position A with RC 1) only when I try to process IB GR in transaction VL31N.
This problem does not occur in other Material related transaction.
The Plan that we have problem was created many years ago and also ML was activated at that time.
We did not any changes to ML settings since.
I had revived followings notes:
639675 - Initialization of the actual cost component split
710808 - Activating actual cost comp split: check actual costing
584904 - MIRO: no procurement alternative/wrong price diff in ML
Seems like first one fit our problem the best, but in our cases we do not activated component split after the material ledger production startup and also we do not have such problem besides VL31N. In addition using above solution, even try, would lead to lost of historical data which we would like to avoid.
Does anyone faced similar issue and have an idea how to deal with this?
Thanks,
Rafał
