Never carry datapoints to certain time interval

Hello world

I have a new question. Currently, I am working on the last part of a friends request which consists of several loops at the same time while:

  1. Loop DAQ: acquires data, adds a relative time in seconds, and takes him to a queue of data

  2. Loop of visualization: calculates the different physical properties (requires some calculation time) as the first line of data and displays them on the graphic screen in XY (to be able to see a complete measure). According to what tab, the active user control tab, different sets of XYgraphs is indicated to take into account the different points of view. If the measurement is running (execution key), a second queue of data is fed by data from the first queue

  3. Queue storage: takes the data from the second queue of data and stores it in a spreadsheet file

  4. 2 additional loops to control the motors to the extent

  5. An event loop that checks what buttons are pressed

Hello

Thanks for the reply. This might indeed serve a good function, but I want to be able to see parts of the data previously obtained. The help information or arbitrarily cutting function on average. To remedy this, I came (this weekend) with the following solution:

  • I have added a registry to offset for the while loop that visualizes information

  • This shift register is initialized to 0 DBL

  • Each time that the loop runs, it will need a set of acquired data to a queue. It checks the relative time of this data set, calculates the value floor (so round down the time value) and checks if it is larger than the value stored in the registry change.

  • If TRUE--> show that the value of the data and update the shift register with the rounded value

  • If set to FALSE--> nothing to do

  • Component to display/change a time interval length

    Hi all

    I am trying to decide what would be the best component Swing to take the entry with a length of time. Ideally, I would prefer to avoid the user to type a number in the format (hh: mm: for example) which must be validated and have just a component that don't show / allow a valid entry. I had considered using a component JSpinner, from '00:00:00 ' and let the user 'spin' up to a certain number of hours, minutes, and seconds. In fact, the JSpinner would be ideal if I could work out how to do correctly view and edit this kind of value rather than the date values. At the moment I have a JSpinner configured to use a DateModel and DateEditor and initialized with a blank date. It works because I can ignore all but the values of the time in the date object so that the user can simply define an amount of time "since midnight" that I can effectively deal with the length of the interval. The problem is that using a configured router Date shows the time in a range of 12 hours from 12:00-01:59:59, at no time did the display check to 00:00:00, which, in my case, is that the user must start by as a value. So, to enter a time interval of, say, 30 minutes and 20 seconds, I set the spinner at 12:30:20, account held that currently is 30 minutes and 20 seconds elapsed since midnight.

    Ideally, a time interval should not be tied to a date object at all, but if necessary, just a way of pursuading the spinner shows the time between midnight and 01:00 as departure 00 would be a way around the problem. The ideal solution would be an element that acts much like the Spinner which holds a value behind the scenes as a long in a few seconds, but this value in hh seconds formats for display and does not have the limitation of range 12 hours or 24 hours inherent to the Date in the format of the spinner. I suspect the editor used by a JSpinner and model manipulation could achieve this goal, but Oracle on JSpinners's article will little or no details on what can make a custom editor and how etc.

    So, anyone know how I could reach or the other of these ends, displaying the time in a cone of Date from 0 rather than 12 or customize a router or another component to take a period of time as an input.

  • Time interval in the output file is different from the sampling frequency

    Hello

    I'm a load at 1000 Hz. cell sampling I send information to the VI "write to a measurement file. When I opened the .tdms in excel, the time interval between samples is 0,00062 seconds instead of 0.001 seconds. Is it possible to change the time interval seconds a.001?

    Kind regards

    Johan Hendrikse

    It has sampling frequencies different - he has simply not an infinite number of them. I should have been a little more clear as to what I wanted. Have you read the specifications? Sampling frequencies are defined as 50 000 / n where n is an integer between 1 and 31. When you specify a rate, the driver will put it to the nearest that the material support. A little arithmetic shows that 50000/31.00062. How do you rate? Will this work with a DAQ Assistant?

    I just talked to Dell support on my problem and this is apparently a known issue with local Europe\UK.  The similarity of our problems might be useful - workaround for me was to settle the Locale\Regional from my PC, where I'm doing it in the United States.  Not the time zone or other settings, to control panel, then "Region and language", then on the first tab, 'Format' box should be set to "English (United States).  Close browsers, start again and it worked for me.

    Might be worth a try if you're not already in US format. (mine was in the United Kingdom).

  • Credential Manager loses the password stored after a certain time

    Hey Microsoft Community.

    I have a small problem with the Manager of credentials Windows under Windows 7, Windows 8 RP, RTM of Windows 8 (have a version of Dreamsparks) and Windows Home Server 2011. When I store connections in the manager like for example to connect to network between machines shares, the manager loses these passwords after a certain time (2-3 days or more). At first I thought that this happens when the computer is rebooted or started because the machines are usually have hibernated in my house - but even when they are not given running loose connections.

    What should I do to fix this? I need the connections, for example for automatic nightly backups.

    with data as

      select to_date('28-Jun-2013 20:00', 'DD-Mon-YYYY HH24:MI') start_time, to_date('28-Jun-2013 23:00', 'DD-Mon-YYYY HH24:MI') end_time from dual
    )
    select start_time, end_time,
           case when lead(to_char(start_time, 'HH24'), 1, (select min(to_char(start_time, 'HH24')) from data)) over (order by to_char(start_time, 'HH24')) not between to_char(start_time, 'HH24') and to_char(end_time, 'HH24')
                  then to_char(end_time, 'HH24:MI') || ' - ' || lead(to_char(start_time, 'HH24:MI'), 1, (select min(to_char(start_time, 'HH24:MI')) from data)) over (order by to_char(start_time, 'HH24:MI'))
                else
                  null
           end period
      from data
    
    START_TIME                END_TIME                  PERIOD
    ------------------------- ------------------------- -------------
    28-Jun-2013 09:00:00      28-Jun-2013 18:00:00      18:00 - 20:00
    28-Jun-2013 20:00:00      28-Jun-2013 23:00:00      23:00 - 09:00
    

    Time information should not be stored in additional fields Varchar, if you have the Date column. You can use Date fields that store the Date and time together.

    Another way to approach this problem is to connect by Clause, or model. Use the search feature to find solutions using these methods too. However, in my opinion, this method is the fastest of all.
