Dwell During Sequence of Blended Lines and Arcs

Hi,
I am trying to create a motion profile using blending that completes an ordered sequence of moves,mostly,it works great. But in some Speed Setting ,it don't work fine that come to a quite small speed as if there is a dwell.
I am using PCI 7334 and the open loop mode.

Hi Scott,
positive values of the blend factor are interpreted as a delay[ms] between consecutive moves. You can change the blend factor for each blend operation.
Running a complete motion sequence in an onboard program is not the intended use case of onboard programming and in fact in such a scenario there are no significant advantages compared to a host program in terms of execution speed and jitter. The reason for that is the fact, that onboard programs run on a quite slow controller in a low-priority thread, so this approach is not recommended.
The most common use case of onboard programming is stopping a move at an event like exceeding a torque limit. Running such a task in an onboard program adds safety, as it runs independently from the (Windows) application.
If your moves are too short and too fast for blending, you shoudl consider using contouring instead. Contouring provides the ultimate flexibility for defining motion profiles, including strictly timed delays.
If you need more information, please add some more specific information to your next post (motion control board type, programming environment, motor type, drive,..)

Need help regarding converting text to Lines and Arcs.

In my program i have text.Lets say the text is JAVA.
Now i need to group that text(JAVA) in the form of line and arcs.
Its like organizing lines and arcs and make it looks like a text(JAVA).
Can we have such a possibilities to do that?
Please help regarding this!!
Thanks in Advance.
Boopathy.

Have a look at TextLayout class (http://java.sun.com/javase/6/docs/api/java/awt/font/TextLayout.html)
Graphics2D g = ...;
Point2D loc = ...;
Font font = Font.getFont("Helvetica-bold-italic");
FontRenderContext frc = g.getFontRenderContext();
TextLayout layout = new TextLayout("This is a string", font, frc);
Shape shape = layout.getOutline(null);

Polylines to Lines and Arcs

I'm getting some metal cut-outs done of a design I did up in Photoshop and converted in Illustrator, but the end product is not that nice because Mr Metalworker has said "the Drawing file is in Polylines (many lines to make up one) because of this the laser takes them as individual contours and cuts it at less than half speed."
He goes on to say that I need to "convert it into ‘lines and arcs’ and not ‘polylines’ then I think we can get to the point where no cleaning, filing or deburring needs to take place."
How do I do this? I'm a bit naive when it comes to this sort of thing and googling has led me to believe I need to do it in a CAD program?

vector info is like a join the dots.
image or pixel art is a grid of different coloured square pixels.
Google will provide much info on this.
Rasterizing is a pixel function. and will not be what you want to do.
image trace is getting closer, but it is not accurate and with cause the issues described by your laser guy.
Illustrator will do strange things with the fill of objects when exporting to DXF. (DXF is probably what you laser guy wants.)
you will need to make sure everything has no fill and a black outline before exporting.
I am guessing but if his machine uses Gcode(and I believe most still do), then he want straight lines and basic arcs.
even getting say an Oval shape in to Gcode is complex.
He should have Cam software to help with this as long as he gets a clean DXF file.
here is part of your art redrawn.
it will give you an idea on what you want it to look like.

HDV sequence has green lines and pink dots after export

I digitized some HDV footage from a Sony HVR-VIU into Final cut Pro 7. Everything worked normally through the edit. After exporting the sequence as a quicktime movie, it played back fine as a quicktime. When I attempted to convert it to a media file in Sorenson Squeeze, the file showed up with green lines and pink dots over the picture. To test it differently, I dropped the file into IDVD. Same, result in playback. I've never seen anything like this before, any ideas?

Brad your article was extremely helpful in getting my sequence to work for a DVD. However, I've had success before using the same camera, format, etc., in making DVD's from an HDV sequence, and I'm curious as to what I did wrong this time. The most confusing part to me is that the original quicktime self-contained export played fine through quicktime, but got funky when placed into IDVD and Sorenson's Squeeze compressor. I must have done something wrong up front in digitizing or making settings in FCP, and I'd like to know what it was so I don't do it in the future. Thanks.

Dwell During Blend and onboard blending

I am trying to create a motion profile using blending. Howver I want a dwell (of dfferent times and at different places) during the profile. Is there a way to include dwells/delays in a blended motion profile?
Also, Does anyone have an example of an onboard blend (with or without a dwell)? I have used a series on individual moves but I get a delay between moves which I think is caused by the wait on condtition VI so want to use a blend.
Thanks
Scott

Strokes of line and polyline behave different during zooming - why?

Hello,
I noticed a different behaviour between the a line an a polyline during zooming. The stroke of the line will not be increased while zooming. But the stroke of the polyline will be increased while zooming. I don't understand this behaviour. Is this a feature or a bug? For a better understanding you can execute the following demo:

          elements.getChildren().add(line);
          elements.getChildren().add(polyline);
          root.getChildren().add(elements);
          //init the slider for zooming
          Slider scale = new Slider();

What is the white horizontal line and red vertical line on my brand new ipad mini?

Bought a brand new ipad mini 2 for my sons Christmas, took it out the box and it was during the set up process, ie entering his iTunes and icloud account, a white horizontal line and a red vertical line appeared on the screen and is there all the time now. Have tried switching off and on and resetting, but it is still there. Any ideas??

Hi Tolmivooz,
So the lines didn't appear until you were into the setup?
Does the orientation of the lines change when you rotate the screen?
Thanks for trying the restart and reset. Please see if a restore helps.
Get help with the screen on your iPhone, iPad, or iPod touch - Apple Support
If you see lines, missing sections, discoloration, or poor image quality
Try to restart your device. If you can't restart, reset your device.
If restarting or resetting doesn’t fix the issue, restore your device.
If you still see the issue after you restore, contact Apple Support.
Best,

I wrote a 27 chap. book on my iMac from ****. B4 I was completely finished, I spent hundreds of hours on-line and in store, and final answer after atty was involved was 1) we've never seen it b4 2) we don't know what it is 3) it's not ur harddrive, softw

finished, at about 26 chaps, 1) hard-drive went out, 2) visited site & then got "ur virus is infected buy us now" pop-ups (only time in 3 year. of using a mac, and 3) (forget what but an issue. Spent hours on-line, and at store. And finally w/an attorney when I kept being told it was user error. (I"m getting to book isssue I promise) During this time, Harddrive was wiped, external b-up replaced, something about "separated" etc. etc. and even computer replaced w/same issues afterward. Final vrdict 1 yr. later: 1_ we've never seen it 2_ we don't know what it is--not a virus, not harddrive malfunciton, not software issue 3_ we don't know how to fix it. Live w/it w/multiple errors and oddities every time you try to type or start all over. Got an attorney, and took it in again, and miractulously, "he" fixed it. However, in meantime, I wrote many duplicate chapts. when I couldn't find missing, or edited, some, etc.
Everything was writen in Pages, chapt. by chapt. Now I have a 27 chap. book(my first) in pieces--w/many duplicate or slightlychanged chapters all over the computer. I'm trying to reconstruct. Some chaps. I just can't find, some are garbled, some do strange things like left justifying and changing to single space (and can't change back to double, just have to erase and start over, on those old documents. Needless to say I have felt so defeated it's been really hard to get back to the almost finished book for last re-write.
The Questions: 1)I'm trying to find the chapters, and as I find and edit them I need to know how to make this massive achievement work. Should I continue w/chapter by chapt until all are finished? Or start putting them into single document as they are finished? How do I find anything? If I put finished in PDF to send to publisher, even tho it's my PDF, I can't go back and edit my own, except in a duplicate entire document, is that correct?
I cant' find the string to start unraveling this mess. I do have hardcopies made and presented to writing group so need to edit those chapters.
I'm used to paper typewritten copies of everything for manipulation, and I know things now I should have done on the Mac but didn't when I started. (I"m also having trouble getting a Table of Contents to work, which is making it doubly hard to find anything.)
To sum it up, I think, How do I write a book, with chapters (no technical sstuff, only a few footnotes & I may group them at the back of the book.) as far as manipulating documetns/folders, have ready for export, etc. Probably too long a question so go ahead and chew me out. (And I havent' used any other document except Text Edit in years.) I am overwhelmed an book is wasting away.

If you are wondering why you are not getting any responses, it is because you have vented a complaint without any details that make any sense or give anyone something to work on.
If you want help, I suggest actually detailing what has happened, with versions of software etc. Anything that would let us assist.
As a start I am guessing that you have not really got the hang of "How it all works". Firstly download the Pages09_UserGuide.pdf from under the Help menu. Read that and view the Video Tutorials in the same place. A good addition would be the iWork 09 Missing manual book and something to help you learn how to use your Mac.

Questions on porting family plan lines and a prorated final bill?

Hey there! I've done some searches on the board before posting and encountered tidbits of information I found useful, but I couldn't get all of my lingering questions answered from older posts so here's my situation:
My number is the primary number on a family plan (3 lines, mine included) with Verizon, and I'm considering porting it along with the two other lines elsewhere. All three lines are no longer in a contract and are month-to-month (the 2-year agreements ended many months ago and none of the lines have been upgraded or anything since then). I'm planning to move them all to separate prepaid services through another carrier.
I'm doing my best to gather enough information about how to go about moving all three of these family plan lines with the least amount of hassle , so I've got some questions I hope I can get answered. Thanks for any assistance!
This is my understanding:
-I'll need to contact my new carrier to have a given number ported, correct? And that line will be subsequently cancelled on Verizon's end, with no ETFs since none of the lines are tied to a contract?
-Should I port the second and third lines first and not port the primary number (mine) first, so asto not cancel all the lines of service before they're ported? I'm okay porting one number at a time AKA separately instead of all at once if that simplifies the transfer process.
-When the porting process takes place and my Verizon service is cancelled, does Verizon prorate the remaining days on my billing period from the date it's cancelled, or do they still bill up to the end of the cycle? I hear it's better to wait until the end of my billing cycle (which for me is the 9th of every month) to initiate the transfer(s) so that I don't have any billing issues, but moving all three numbers on one day (even separately) sounds kinda daunting.
-Do the phones I currently have under Verizon simply "disconnect" or deactivate once service is cancelled? Will they no longer be associated with my family plan lines and therefore be free to be resold or handed off to other family members who are using Verizon? I notice many phones on eBay/Craigslist list a "cleared ESN" as a requirement for someone to activate a used phone on Verizon and wanted to know what that was about.
Thanks for any help on these concerns!

This is my understanding:
-I'll need to contact my new carrier to have a given number ported, correct? And that line will be subsequently cancelled on Verizon's end, with no ETFs since none of the lines are tied to a contract? All correct - the port happens via the NEW carrier.
-Should I port the second and third lines first and not port the primary number (mine) first, so asto not cancel all the lines of service before they're ported? I'm okay porting one number at a time AKA separately instead of all at once if that simplifies the transfer process. You can do it this way - but based on your next question, you wouldn't want to do it this way. You can't do both!!
-When the porting process takes place and my Verizon service is cancelled, does Verizon prorate the remaining days on my billing period from the date it's cancelled, or do they still bill up to the end of the cycle? You have already paid for the current month's service - you are billed in advance for the coming month. What WILL be billed is any texting, roaming calls, data charges, etc, that have occurred during the month that were NOT billed in advance. I hear it's better to wait until the end of my billing cycle (which for me is the 9th of every month) to initiate the transfer(s) so that I don't have any billing issues, but moving all three numbers on one day (even separately) sounds kinda daunting. But YOU don't have to do anything - your new carrier will deal with it, and it seems to me it would be better to end the service on all three at one time, since it is one account. You can ask your new carrier what they recommend. There should be no issues with porting all three lines at once.
-Do the phones I currently have under Verizon simply "disconnect" or deactivate once service is cancelled?Yes - once the number is ported to the new carrier, the phones will no longer work until they are activated with another number. Will they no longer be associated with my family plan lines and therefore be free to be resold or handed off to other family members who are using Verizon? This is correct, and another reason for doing the port at the end of a billing cycle. Issues have come up with transfers done mid cycle - and because the account had been billed and paid for the full month's service, the phone's ESN was not released until the end of the billing cycle. I notice many phones on eBay/Craigslist list a "cleared ESN" as a requirement for someone to activate a used phone on Verizon and wanted to know what that was about.
Thanks for any help on these concerns!
It may take several days for the numbers to fully port over and have all services working correctly, and for the old phones to be fully "released" from your account to be used on another Verizon account. I would wait a week or so after the port, then call CS and check the ESN status of the old phones to see if they are "clear".
Hope this answers most of your questions. Post back if you need further clarification.

Crackly phone line and broadband disconnecting

For a month or two i have been having problems with our phone line and broadband connection. The phone line is extremely noisy (interferance) and when you make a call or recieve a call the broadband disconnects. I have tried different filters, routers and wires but no good. I have conducted a quiet line test and the result was i could hear nothing on the line. When i unplug the hub and just have the phone connected to the socket the noise on the phone has gone and their is no problem, connecting the hub make the noise come back. As a result of all this my broadband speeds are very low.
Here is my hub stats and a bt whole sale speed test.

Any advice would be helpful thank you
Solved!
Go to Solution.

your drops in connection have at one point reconnected with a far lower speed than normal resulting in the low ip profile. if you stay conencted 24/7 for 3/5 days the profile will correct itself for your current connection speed
I would as john46 suggested connected to test socket with a new filter and see if that helps

Sequence of material line items in Project

Hi all,
I have transfered the BOM using CN33 in the project, the systems is configured such a way that after BOM upload the system creates PR automatically but, when the PR is created in the system the sequence of the line item material is not same as that of in BOM. How this has to be solved?
Best Regards,
Nitesh H Panchal

Hi,
I am aslo using BAPI for uploading material component. What it is doing , it is creating the line item number in the sequence I am planning . Like if I planned material A first then it is creating line item number for that irrespective of its activity and WBS number.

Lines and title flashing across the program monitor and in final export

I'm seeing very thin lines flashing across the program monitor when playing a complex sequence with 7 video tracks. They draw at various angles and span the entire screen. There can be one or more showing at any time. They are colored and each line appears to be only one color, but different lines can be different colors. Some lines are solid, others are dashed. There is also a ghosty-white representation of one of my titles flashing around the screen for only a frame or two, then it flashes somewhere else.
Sequences and Tracks:
Base Sequence: AVCHD with disolves and color correction
Next Sequence Layer: Base Sequence placed on tracks 1 and 2. Motion is applied to both tracks. LInearWipe and Opacity are applied to Track 2.
(This creates an image in the center of the screen with a reflection.)
Next Sequence Layer (1st track of the final 7): Animates Basic3D and Motion (position, scaling)
2nd, 3rd and 4th of the seven are just like the1st. So there are 4 video screens flying around with reflections and perspective. Kind of like the iTunes album art widget - screen flies in, goes center stage, then flies back.
Layers 5 to 7 are titles. They are also nested sequences having reflections and Basic3D, but their positions are not animated.
My system:
Phenom II x6 1055T
8 Gb DDR3 1333
3 Drives 7200 rpm (one program, one preview/conforming, one video)
nVidia GeForce GTX 260 (3 fans attached)
3 Case fans plus the side is open - running very cool
MSI 890GXM-G65 Mobo
My Project:
Originated as a CS4 project, opened with CS5 and converted (did not import). Fixed all the title screwups, missing fonts, graphics, hooked up the off-line media etc etc. There are a couple of 1.5 hour nested AVCHD multi-camera sequences which look and play great. Then there are 2 of these monster sequences which are actually used as DVD menus and are about 44 seconds each. When I render these 7 layer menu sequences and play them back, these lines start flashing across the screen.
Of course the GTX 260 has the GPU unlocked and that works great for the 1.5 hour programs. But if I attempt to render the 44 second monsters Premier stops responding and I have to EndTask it (all CPUs drop to idle while not responding). These monster sequences might test the power of the Quadro CX. So when I work with the menu sequences, I set Premiere to use software GPU and not MPE. Then I can render (2 hours render time to preview 44 seconds with six cores at near 100%). So it does render, slowly.
I'm exporting an mpeg2 file now and will let you know if the lines show up in the final rendering. I can see the lines showing up on the MediaEncoder's small preview screen as it renders. Doesn't give me comfort.
OK worst case scenario. The lines ARE in the final mpeg2 file. Makes the file unusable garbage...
Is anyone else seeing flashing lines and titles?
Here's a link to a still from the export to illustrate the artifacts.(face and name were blanked out by me)

Thanks

The crop workaround was successful for removing the lines - worked great. There was the issue of the ghost text which you can see in the screenshot link provided above. This was not removed by crop. Crop removed the lines, but not the ghost. Thankfully, the 4 point garbage mask did work on the ghost and I was able to eliminate it. I had to apply the garbage mask on the sequence where Basic3D was applied not its parent sequence where VerticalFlip was used. The most important thing is that I've successfully migrated this CS4 project to CS5 and can now take advantage of 64bit processing (more RAM) to tame the beast. I'm using this sequence as a menu for a series of DVDs so my time expended will pay me back again and again.
The asset generating the ghost was built like this...
In the titler: Text was placed over a logo (.tiff file for logo and it was scaled and moved)
Base Sequence: Title was brought to two, stacked tracks. VerticalFlip, and LinearWipe were applied to one which was then moved to look like a reflection of the other
Next Sequence: Layed the Base Sequence down. Applied Basic 3D and moved it's XY position. (This is where I applied the GarbageMask to remove the ghost)
I tried separating the logo from the text thinking that the logo feature of the titler might be the problem. So I used a separate video track and pulled in the .tiff file directly. It didn't eliminate the ghost. Applying the GarbageMask to the base sequence also didn't help. It was only after Basic3D was applied that the ghost would appear. And since I have Basic3D applied to other reflected text-only layers which do not exhibit the ghost artifact, the bug has something to do with the text/graphic combination with VerticalFlip and Basic3D.
To top it all off, I can no longer recreate the problem. I've turned off the garbage mask and it's not showing up. While I was testing, the ghost was easy to recreate, but now I can't do it. So I don't appear to be able to drill down deeper. Perhaps it will come back at some point and I can test it further and update this thread.

Multiple velocity inputs in a sequence of blended moves

I used the template 'Sequence of Blended Vector Moves' in order to synchronize two different motions on two different axes. I am trying, however, to input two different velocity vectors (one for each axis move) and can't seem to find a good way to input both of them as the velocity input only accepts a single input.
Thanks!
Lauren

Hello laf3g,
Have a look at the attached LabVIEW VI. I duped the “Load
Velocity in RPM” VI and allowed for the velocity specification of each axis.
Give this a shot and modify accordingly. I hope this helps

Generate sequence nuumber for line items.

Hi,
Am using jdeveloper 11.1.1.6.0
I have generated a form using master detail. po_header as master and po_line as child in po_line i need to generate the sequence number.
The problem am facing is
If i generate using create sequence in my DB. Its working fine.
consider
I have po_number 1234 for this po_line while i click the add button the sequence number is added. for eg: form 1 to 10 i have the po_line against po_number.
If am created another po_number 12345 for this while i click the add button the sequence number starts from 11...., But it need to be started from 1 since its a different po.
Could anyone help me how to acheive this?
Regards,
Prasad K T,

Hi,
in addition, have a look how you would model the line items in a database schema. Here you would have purchase orders and line items in separate tables that are linked with a foreign key. To uniquely address line items you would have a unique sequence in the line items table. What you are looking for is a combined key (purchase order AND line item ID) to have line items numbered 1 .. 10 (this however, from a database design aspect makes no sense).

How to get uneven distribution of blended lines

Is there a way to achieve uneven distrubution of blended lines in Illustrator CS5? There was one other post on the web asking a similar question to this, which was solved by changing the blend spline.
This works great for objects, but not so much for lines.
Here is an example of what I am looking for where the top is what I would like to achieve and the bottom is the typical blend.

I will now have to read through to see how to calculate the distance
If you're trying to achieve a realistic distribution as if viewing the side of uniform spaced lines on a cylinder, construct it by basic orthographic projection.
