How to "skip" part of a signal

Hey everyone,
I'm still very new to LabVEIW
I'm writing a code to control a pair of mirrors which will scan across a designated area, one on x-axis and on the y-axis. The movement is defined by two triangle waves (for simplicity at the time being, I may change it later) and will move at different frequencies so that the result is a zig-zag pattern across the area as the two mirros combine.
The problem I'm having is that I don't really want the mirrors to scan back across the area when they're done. As things stand, the scan crosses the area and comes back, but I want it to scan in one direction and as the y-axis mirror returns to the starting position, the x-axis mirror stops and waits for it, so it's not scanning back across the same area. I've created the code I'm using with some sub vi's but I'm pretty stuck as to how I can stop this from happening and the help function hasn't made anything any clearer for me
The two phsyical channels in the vi I'm posting go to the outputs of a DAQPad 6015, which are in turn linked to an oscilloscope so I can see the physical results of what I'm doing. I won't be linking any of this to a real system till I have it worked out
Thanks in advance,
Ben

Hi Ben,
I think this is what you're shooting for, however the graph reaches -1 amplitude at 0.475 seconds.

QuickTime 10.0 Screen Recording randomly skips parts of the recording?

I'm using the QuickTime Player to record some gameplay on my computer and sometimes, randomly, it skips part of the video. Sometimes its just a minute or 2 and sometimes its 15 minutes. I don't know why or how this could possibly happens, but it does. I have 366GB of space on my computer left so space is not an issue. I don't know what is. Please help

Bump. I'm having this trouble too, on both my iMac and my Macbook. I've tried every combination of events I can think of that might make this happen (switching windows, switching Spaces, etc. etc.), but the problem is so random and intermittent. Sometimes it records fine and I end up with a full recording, sometimes the middle is gone, sometimes just the end. The file size doesn't seem to matter; I have some good recordings that are nearly 500MB, and some that failed when they are only 30MB (and I have well over 300GB free). It's really annoying to not know until you've done 30 minutes of work that the middle is missing from the recording, and have no idea whatsoever even how to work around the issue.

How can you post comments during signal aquisition?

How can you post comments during signal aquisition? For example, while acquiring your signal, you want to post a comment which the temperature reads at "30 seconds" from your relative start time (t=34 sec into recording)
I have the LE package where events, alarms, etc cannot be used. Are there other ways that the user can mark an "event" during recording?

Hey hkim,
If you know how long it will be before you want a message to pop up you can simply include a sequence structure and in the first sequence have a wait time of your desired length and have the message pop up and display in the second sequence frame.

How to skip line for delimited file type?

Hi, i wanna ask how to skip (example: the first two line) for delimited file type?
Thanks...
Here is my script
Function NY_Skip06Center [strField, strRecord]
' FDM DataPump Import Script:
'Created by: FDM_Admin
'Date created: 2/28/2006
Dim strEntity
'Check first two characters of entity
For strEntity = 1 to 6
'Skip line
Res.PblnSKip = True
Next strEntity
End if
End Function
But it returns this error when imported
Error: An error occurred importing the file.
Detail: Object variable or With block variable not set
Anyone knows what's wrong

strAcc = DW.Utilities.fParseString (strField, 1, 1, chr(9))
I didn't look closely enough last time. The above is illogical. The parsestring function parses a string based on a delimiter.
The function has these arguments:
String to Parse
How many fields are in the string
The parsed field to return
Field delimiter
In the above, strField is returning the field specified in your import format. You are also saying that there is a total of 1 field. If that were the case, you wouldn't need to parse anything.
I am guessing that your call needs to look something more like this:
strAcc = DW.Utilities.fParseString (*strRecord*, *8*, 1, chr(9))
Make sense?
If not, maybe you can include a few sample lines from your data file and that will make it easier to help you.
Is your import format fixed or delimited?

How to skip a record in flat file to idoc scenario?

Hi,
Anybody have good suggestions on how to skip a record(xi not process the record) based on certain conditions? I don't want to use bpm, anybody has experience with file to idoc can advise how to deal with this situation?
Thanks,
Meg

Meg,
Its very clear. It can be easily done. I hope u might be knowing about Michal's changing the IDOC occurence blog. Based on that blog change the IDOC occurence to 0...Unbounded.
Now map all the necessary fields to the target IDOC. On the IDOC root node set condition from source if the source field is not Delete then create IDOC else don't create.
Source --- If without else[Check condition if the source is delete] -
IDOC(root node).

I bought the iPad Mini and found it icloud account and I do not know how to skip account icloud

Do you mean that you bought it second-hand and the previous owner hasn't removed it from their account ? If you do then you will need to contact the person that you bought it from, only they can remove it from their account : http://support.apple.com/kb/TS4515
If you mean something else ... ?

Living in apartment, here it has only wireless (no wired cable in the room). I've an airport express (new ) so how can I do for extending signal (wireless) for using in myroom

Living in an apartment, here it has only wireless (no wired cable in the room) signal using for the internet connection. I've an airport express (new) ,so how can I do for extending signal (wireless) for using in myroom. because the wireless signal is so weak.

Unfortunately, you won't be able to. In order to do so, you would have to configure both the AirPort Express and the other wireless router for a WDS. Since it will unlikely that the other router is another AirPort, nor will you have the ability to administer it, you won't be able to get this accomplished.

How do i split the digital signal for PIP?

My tv requires 2 separate A/V inputs to use PIP. How do I split the incoming signal without affecting the signal strength to STB? Everytime I connect a slpitter, the signal looses stregth and I can't HD out of my STB only digital, not HD. Is there a fix or solution for this problem?

It is just the nature of beast in that when you add a 2:1 splitter, you will lose 3.5dbm of signal strength (more loss per leg the larger the splitter.. IIRC a 4:1 splitter a is 7 or 7.5 dbm loss.)
How many splitters do you currently have from the ONT to that STB? Do you have any 4:1 splitters in the path that you could swap with a 3:1 or 2:1 (leaving no open legs)?
I will leave it to someone else to recommeand a MOCA amplifier, but that may be you only possible solution. It would have to be a MoCA amplifier, as the STB requires 1150Mhz to receive guide info, etc.. A traditional signal booster typically does not pass frequencies higher that 850-950Mhz.

How to skip selection screen? Please help!

Hi Experts,
       I have a report program that has a default selection screen (1000) and ALV output. First selection screen is displayed and on execution ALV is shown.
My requirement is, if the user is not authorized to run this report then selection screen should be skipped and instead display a error page. This error page is nothing but some write statements in ABAP displaying error icon and error info.
Currently I have written the authorization check in the INITIALIZATION event. Here I am setting a flag if the user is not authorized followed by "write" statements showing error info.
But when I run the report, error info is not displayed and instead selection screen loads even though the user is not authorized. I have written the selection screen code in the TOP include.
So what shall I do? How to skip the selection screen?
Are there any other better ways to handle my case?
Thanks
Gopal

Got it.
CODE:
REPORT zzsorttry                               .
SELECTION-SCREEN BEGIN OF SCREEN 1001.
PARAMETERS : p_vbeln TYPE vbak-vbeln.
SELECTION-SCREEN END OF SCREEN 1001.
DATA : flag.
INITIALIZATION.
*C-- Put your authorization check here.
IF 1 = 1.
    flag = 1.
    LEAVE TO LIST-PROCESSING .
ELSE.
    CALL selection-screen 1001.
ENDIF.
START-OF-SELECTION.
IF flag IS NOT INITIAL.
    CLEAR flag.
    WRITE: 'User', sy-uname , 'not authorized to use this report'.
ENDIF.

thanks in advance to all the PM guru's

How to skip the spaces, ' etc when passing the parameter to srw.run_report?

Hi, I have got problem with passing parameter to srw.run_report. It seems it doesn't take the special symbols such as space, ', etc.. the statement is like:
srw.run_report('report=test1 p_name='| |:p_title);
if :p_title is "JOE", there is no problem to pass it, but if the :p_title is "JOE LI", then the value of the parameter can be passed to p_name.
Does any one know how to skip those special symbols in the string when passing it to srw.run_report. Thank you very much.
Joe

Hi,
Try this :
srw.run_report('report=test1 p_name='| |
chr(34)| |:p_title| |chr(34)
);
