Online zero reference to several points of

I have several x, y points.  I would like to point there chose 2 and set them to zero as a reference line, then calculate the gap of all other points of this reference line.  LabVIEW has a function that can do this.  Thank you.

Just do a linear fit for two points and subtract the result from all data points.  See example (quick and dirty and potentially buggy).

  • Track of several points of BBMap

    Hello

    Since in my app, I am interested in launching BBMaps and the route of several locations on the map.  I see where I can draw 1 point with setLatitude() and setLongitude(), is there a way to do for more than one?

    Thanks in advance,

    Glenn.

    Glenn,

    If you pass in a document to the location that contains several points, you can view several points on the map at the same time.  See the following article:

    Variable binding is preferred: P23_ID you can also use & P23_ID. (variable substitution notation).

    Bind variable and static text substitution references are not interchangeable. For example, static text substitution references cannot be used in allocation targets:

    :P23_ID  := 'foo';  -- valid
    &P23_ID. := 'bar'; -- syntax error (or something weird or sinister due to SQL injection)
    

    Substituting static text references should be avoided in SQL and PL/SQL code because of the risk of behavior topic SQL injection and / odd error because of values containing quotes, etc.

  • Divide a line into several points

    I see that I can use SDO_LRS. SPLIT_GEOM_SEGMENT to divide a line into one only point (and get 2 lines resulting).

    However, someone at - it an idea how can I split a line, at several points, in several segments? I need to do for the number of lines, so a function or procedure would be nice as appropriate.

    Thank you

  • Multitouch touch several points of confusion

    I'm currently implementing several points of contact for the first time.  I tested on a Samsung Galaxy Tab 2 7.0; If I device USB debugging, AIR indicates that the device supports 2 points of contact and touch events are supported.

    The app I'm trying is in its infancy, so there's not much going on right now. I have two SimpleButtons that I am putting in place so that the user can press both at the same time, but I can't make it work right. If I hold the first button and then press the second button, the first button is pressed and the second button does not recognize a press (the SimpleButton doesn't change even its origins to the depressed state). If I want the second button, and then press the first button, the first button does nothing, and the second button is released (in my code and visually).

    public function enableButtons (): void {}

    Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;

    trace ("supportsTouchEvents:" + Multitouch.supportsTouchEvents);

    Button1.addEventListener (TouchEvent.TOUCH_BEGIN, onHoldButton, false, 0, true);

    Button2.addEventListener (TouchEvent.TOUCH_BEGIN, onHoldButton, false, 0, true);

    }

    private void onHoldButton(event:TouchEvent):void {}

    trace ("the" + event.target.name);

    var button: SimpleButton = event.currentTarget as SimpleButton;

    button.removeEventListener (TouchEvent.TOUCH_BEGIN, onHoldButton);

    button.addEventListener (TouchEvent.TOUCH_END, onReleaseButton, false, 0, true);

    button.addEventListener (TouchEvent.TOUCH_OUT, onReleaseButton, false, 0, true);

    }

    private void onReleaseButton(event:TouchEvent):void {}

    trace ("BUTTON of UNLOCK" + event.target.name);

    var button: SimpleButton = event.currentTarget as SimpleButton;

    button.addEventListener (TouchEvent.TOUCH_BEGIN, onHoldButton, false, 0, true);

    button.removeEventListener (TouchEvent.TOUCH_END, onReleaseButton);

    button.removeEventListener (TouchEvent.TOUCH_OUT, onReleaseButton);

    }

    I'm doing something wrong here? Do SimpleButtons support multitouch?

    Can't seem to edit my post, so here's the short of it based on your findings.

    Here's the answer: SimpleButton does NOT support Multitouch.

    You can mark this or your own answer as being correct.

    I'm looking to store data such as those acquired with an optical spectrum for several XY points Analyzer and recall the optical spectrum for a specified point? Currently, I am looking at writing to the file of measure and reading of the measures such as the options file, but I'm not sure how to name each piece and the data and to recall them correctly. Are there examples where this has been done? any help will be greatly appreciated.

    Hello

    I am a beginner of labview.  Here is a screenshot of the program. It provides information in real time to a patient when walking from their foot position, random target (points Exchange with each step) and a reference point (constant).  At present, data from three points are grouped in the same plot on the graph XY.  In the graphics property, when I change the color for field 0, every color change.  I tried to connect the XY graph in table built above, but a cut wire it occurs (connected 2 groups with different content).

    Any help would be great!  Thank you

  • Several points of access Cisco Aironet 1131AG and same SSID?

    We have several Cisco Aironet 1131AG, all wired devices on a switch (2560) Cisco L2 which is connected to the L3 switch (3550). We have assigned a VLAN for access point to the L3 switch which acts as a vtp Server (L2 switch is vtp client). All the ap will have a static ip address and all will have the same SSID and no security, and they will use several channels (e.g. 1,6,11).  They will work in 3 floors for a roaming wireless client. We not using any wireless controller.

    So my question is this: how to configure the same APs-all with a different ip address, can we use L3 switch to create the dhcp server to access points VLAN (pool for guests) and the rest of the static ip address for the ap? One of the ap can be WDS and on the same radius server local time with users without Cisco Secure ACS or similar controller or I did not understand this very well :-). I followed the guide http://www.cisco.com/en/US/docs/wireless/access_point/12.3_2_JA/configuration/guide/s32roamg.html for WDS where Abu Cisco ACS part is a problem, so I can use the same ap as a Local authenticator as a guide http://www.cisco.com/en/US/docs/wireless/access_point/12.3_4_JA/configuration/guide/s34local.html#wp1035723.

    Thank you very much...

    Well, just so you know, WDS, and local RADIUS authentication is necessary only if you use authentication on your wireless connection.  You say that you do not plan to use security, so it's not necessary.  However, I highly recommend at least using a simple WPA2-PSK to lock your connection, otherwise you might end up giving free Internet access at best and at worst you could give access to the computers and corporate servers.  If you want to reuse a 802. 1 x or WPA authentication method, then Yes, you can use an AP as RADIUS and to improve WDS Server authenticated to roaming, but this is much more limited than the use of a Cisco ACS.

    As for your other questions, Yes, your APs can all be configured the same except for at least three settings: IP address, hostname, and channel.  Configure your static IP addresses on the interface of the PA BVI1.  Do not place it on the Radio or Ethernet interfaces, because if one of these interfaces goes down, you lose the ability to configure the AP, so it's best to use the BVI1 interface.

    And Yes, configure a DHCP scope for your customers on your L3 switch is good design, or you can also use your DHCP server on a different subnet by using the command of support-ip address on the interface of L3.  I hope this helps!  Let me know if you need help to set all this up.

    Merry Christmas!

    Hello, I tried to find a way to do the summation of a table, the sum of 19 points at a time, leaving me with another table.  I feel like this has a simple solution, but I'm not sure how.

    Thank you.

    A time loop that contains the subset of the table can do.

  • Several points of access WAP300N just stop working

    I have 3 WAP300Ns in my office, all with the same SID.  They will work for several days, then stop working - will not respond to the ping, etc.  I do not think that all fail at the same time, but seems it tends to be in a group.  (I know they are all 3 down when I can't get Wifi)  Turn off and turn on again gets working them again.  All have the latest firmware.  I tried different frequencies but doesn't seem to help. Very frustrating.  Any suggestions?

    Lets see what are the results of a disabling WPS.

  • Several Points on the maps

    Hello

    Anyone know how to plot multiple points on a map? I think it's something to do with the blackberry.invoke.MapsArguments (locationDocument: Document) but I don't know how to use it. I tried:

    var document = "";
    
    var args = new blackberry.invoke.MapsArguments(document);
    blackberry.invoke.invoke(blackberry.invoke.APP_MAPS, args);
    

    I can trace a single point with:

    var args = new blackberry.invoke.MapsArguments(43.26, -80.30);
    blackberry.invoke.invoke(blackberry.invoke.APP_MAPS, args);
    

    Kind regards

    I messed around with different XML structures and got it working:

    var xmlString = '';
    var parser = new DOMParser();
    var doc = parser.parseFromString(xmlString, "text/xml");
    var args = new blackberry.invoke.MapsArguments(doc);
    blackberry.invoke.invoke(blackberry.invoke.APP_MAPS, args);
    

    Don't forget: You must multiply the coords per 100,000 (54.97781, so -1.61396 is actually 5497781,-161396).

    More information on the elements XML here: http://docs.blackberry.com/en/developers/deliverables/11944/XML_element_location_893142_11.jsp and http://docs.blackberry.com/en/developers/deliverables/11944/XML_element_lbs_893141_11.jsp

    Thank you for pointing me in the right direction, Tim!
