• the analysis of data from a legacy in the form of bytes bluetooth

  Hi, Iam execution of java for MYGlucoHealth code monitor. I have to catch the bluetooth through my application data and analyze format. (later I store in the SQLite database). But according to the specification of the Protocol had, I do not understand how to read and analyze. I know how to pair the device to my request. But I do not know how to parse the bytes of data according to the Protocol of the device specification.
  
  Can someone tell me how to do this. All done with this kind of coding?
  
  Thnaks in advance,

• the analysis of data and to help to cite a delimiter

  I found this code large piece that is almost what I want (see below).
  Can someone tell me what I need to do in order to change the delimiter from "," to "' (use
  an apostrophe a delimiter. Is there some sort of escape sequence I need to do in the service?
  
  To ease this function, I would probably want to be able to spend in any delimiter character
  delimiter instead of coding hard within the service.
  
  
  An example on how to change would be greatly appreciated

  You can pass the delimiter to the function like this:

  create or replace function get_token(
  the_list varchar2,
  the_index number,
  delim VARCHAR2
  )
  

  and then call it using single quote as a delimiter. (Note that you must type two single quotes to escape):

  select
  get_token('foo''bar''baz',1, ''''), -- 'foo'
  get_token('foo''bar''baz',3, '''')  -- 'baz'

• Groovy Script to find the difference between Dates

  I am trying to build a script that takes a date from a RequestField and calculates the number of days between this date and the current date (from session).

  So far, I have a problem, the analysis to-date from the RequestField chain. I found this code but it doesn't seem to work...

  date = new Date().parse('yyyy/MM/dd', '1973/07/09')
  

  I get the following error...

  Error Message: groovy.lang.MissingMethodException: No signature of method: java.util.Date.parse() is applicable for argument types: (java.lang.String, java.lang.String) values: {"yyyy/MM/dd", "1973/07/09"}
  

  Any help would be greatly appreciated.

  Hello

  What version of server? The extract you have here works fine on mine (563).

  This also works for me

  new java.text.SimpleDateFormat('yyyy/MM/dd').parse('1973/07/09')

• How do 9229 trigger by analysis of data

  Since 9229 (USB casing) has no external analog trigger; the signal lasts 12 seconds.

  I need to scan data collection the long, until the trigger threshold voltage is detected, then beginning to collect 12 seconds signal.

  But after the detection threshold, some data may already lost when the start of collection time 12 seconds.

  Also ' How do make a scan ", the scan to read th data should be in a loop. If set the duration for each big loop, then maybe the loss of data, but if too samll, then can make the Windows.

  Any suggestion how to read the analysis of data from the device. Thank you.

  Hi Turbot,

  You can just continuously sample and store the data in the table.

  If the size of the data is greater than 12 second pad just outside, and the threshold is reached, use the subset of table data to select just 12 second part.

  You can see my attached sample for more information.

• What is the speed of data transmission when using the dashboard of data?

  Hello, everyone, I've seen it doesn't matter if an iphone or a Chinese tablet is used, the speed of transmission of data with the shared Variables and dashboard of data is almost the same and is at reduced speed. Does anyone know how I could measure this baud rate? Thank you in advance.

  Hello there;

  The rate of updating the dashboard data for 1.0 is set to 1 second of webservices and 0.2 second for variable network shared, of course depends on the amount of information on the network continuously. On the second version of the dashboard of data, you can specify your update frequency within a range

  You can find this info in this KB

  Hope this info helps.

• The analysis of the data of a string of series

  Alert LabVIEW Express 7

  Sorry, all I have to work with and there is no budget at the moment to upgrade.

  Hello, I am in phase 1 (data transfer reliable to labview) 24/7 of my small Miettinen, who is to display and record data environmental Lab 24/7 our Fisher 02-403 digital barometer that has a serial port. In fact, it came with the software, but no one here seems to like use it so I'll try to find something more intuitive. I can't find any info at all about I/O with this device, so I'm reverse engineering. I'm sure that you cannot write anything to this device only read.

  I started with the connection of the device and the interface with NOR measure and automation and received the following string: P,43,1019,44,31,01,0023.0\r\n.

  I tried to use the Labview 7 Express e/s Companion Instrument, selected 1 COMM, changed the timeout to 5000 (trial and error), added a step reading and analysis, ran and received the following string: P, 43,0999, 44,41, 01,0018.0, XX. After well guess, I determined that the values I have in bold change with the environment and the other 3 are always the same idea 9no what they represent). Alphabetical 1 in bold represents the tendency of climate S sunny = P = C sunny cloudy = etc., the value 2 is the atmospheric pressure in hPa, the 3rd is % relative humidity and the last is the temperature in Deg. C.

  At first, I tried to create simply chips for data I want and operation loop the wizard of e/s in awhile, but often error messages obtained suggesting that I need to define all the tokens in the string. I did it and it worked, then I opened the front panel to access the underlying schemas whence I came with the attached VI. I left this race for more than 24 hours, no error, seems good.

  My question on this forum is, can I simplify this VI losing a part of the analysis of the data that I don't need at this point?

  Please let me know if you can not access this VI maybe I can do a screenshot or something.

  Thank you

  Doug

  Yes, it can be simplified to just a bit.

  

  Since you are new to LabVIEW, you can start with the basic tutorial.

• the analysis of string data

  Hi all

  I got the series communation data string in this format:

  Bridge of fuse HtrPwrV VDispV/C PAO V/C DTM V/C DiffC NC
  OK VALIDATES 1.80 0.95 3.16 0.53 537 29.6
  369 647 110

  And I want to extract some value from it. I realized that they are separated with spaces between them. So I thought about transfer them into an array and then extract some lines/columns there. But I don't know how to do.

  Could you give me an idea. Or if you have a better way, then please show me!

  Thank you

  Here is a way.

• Single SQL query for the analysis of the date of customs declaration under the table of Stock codes

  Dear all,

  
  

  Please tell us a single SQL query for the below,
  

  We have a Table of Stock as shown below,

  STOCK_TABLE

   

  ITEM_CODE (item code)

  BAT_NO

  (lot no.)

  TXN_CODE

  (transaction code)

  DOC_NO

  (number)

  BOE_DT

  (date of the customs declaration)

  I1

  B1

  I1

  I2

  I3

  B70

  I4

  B80

  I5

  B90

  T102

  1234

  JULY 2, 2015

  I6

  B100

  We have to find the date of customs declaration (i.e. the date when the items have come under this particular table) for items that are not attached to any document (that is, who have TXN_CODE, DOC_NO and BOE_DT fields with a NULL value).

  For each item in the table of actions, which is not attached to any document, the customs declaration date is calculated as follows.

  1. If (code section, lot number) combination is present under HISTORY_TABLE, the date of customs declaration will receive the UPDT_DT, the transaction code (TXN_CODE) is an IN or transactions (which can be analyzed from the TRANSACTIONS table).

  2. If (code section, lot number) combination is NOT currently at the HISTORY_TABLE (or) the transaction code respective to item - batch number combination code is an operation then customs declaration date will be the date of the document (DOC_DT) that we receive from one of the 3 tables IN_TABLE_HEAD that contains the element of that particular lot.

• If the case 1 and case 2 fails, our customs declaration date will be the last date of document (DOC_DT) that we receive from one of the 3 tables IN_TABLE_HEAD containing that particular item and the BAT_NO in expected results will be that corresponding to this document, as appropriate, to another NULL.

• If the case 1 or case 2 is successful, the value of the last field (in the output expected, shown further below) BATCH_YN will be 'Y', because it fits the lot. Otherwise it will be 'n'.

• Analysis of the gaps in dates

  Hello

  Oracle 10.2.0.4

  Red Hat Linux

  We have a report that is not scaling as the company increases in size and I am looking for some advice to setting / better approaches to a problem.

  The report needs to find employees who while working in a dangerous environment (high / low temperature, wet conditions, etc.) did not have relevant qualifications.

  The report creates a temporary table containing the EMP_ID, start date in a dangerous environment, and the end date in this environment.  There are also about 200 bytes of other areas.

  Then look for any day during this period where there is not a comprehensive relevant qualification / certification.  Certifications are stored in a simple table, containing the EMP_ID, the ID of the qualification, a dt start and an option end dt.  If the end dt is null, then the qualification is supposed to be in place forever.

  CREATE TABLE EMP_DANGER AS

  SELECT A.EMP_ID

  , to_date('01-JAN-2005','dd-mon-yyyy') 'START_DT '.

  , to_date('01-JAN-2016','dd-mon-yyyy') 'END_DT '.

  , 'FILLERFILLERFILLERFILLERFILLERFILLERFILLERFILLERFILLERFILLERFILLERFILLERFILLERFILLERFILLERFILLERFILLER' 'FILLER '.

  OF (to_char (rownum) SELECT 'EMP_ID' from dual connect by level < = 100000) has

  /

  CREATE TABLE EMP_QUAL AS

  SELECT A.EMP_ID

  B.QUAL_ID

  , to_date('01-JAN-2005','dd-mon-yyyy') 'START_DT '.

  , to_date('01-JAN-2016','dd-mon-yyyy') 'END_DT '.

  OF (to_char (rownum) SELECT 'EMP_ID' from dual connect by level < = 100000) has

  , (SELECT DECODER (ROWNUM, 1, 'A', 2, "B", "C", 3, 4, has ', 5, 'E') 'QUAL_ID' from dual connect by level < = 5) B

  /

  DELETE FROM EMP_QUAL WHERE EMP_ID = '3' AND QUAL_ID = 'B '.

  /

  UPDATE EMP_QUAL SET END_DT = 1 January 2013 "where EMP_ID = '3' and QUAL_ID = 'A'

  /

  UPDATE EMP_QUAL SET START_DT = 3 January 2013 ' where EMP_ID = "3" AND QUAL_ID = "C".

  /

  ENGAGE

  /

  -Assuming for the moment that the A, B or C skills are necessary if we're working in a dangerous environment

  -You can see that EMP_ID 3 does not have a valid qualification for January 2, 2013.

  -For the moment, we have a few SQL that performs

  SELECT A.EMP_ID, B.DATE_SCAN, "no qualification valid."

  OF EMP_DANGER HAS

  , (SELECT to_date('01-JAN-1980','dd-mon-yyyy') + rownum 'DATE_SCAN' from dual connect by level < = 10000) B

  WHERE B.DATE_SCAN BETWEEN A.START_DT AND A.END_DT

  AND NOT EXISTS (SELECT 1 C EMP_QUAL

  WHERE C.EMP_ID = A.EMP_ID

  AND C.QUAL_ID IN ('A', 'B', 'C')

  AND B.DATE_SCAN > = C.START_DT

  AND (B.DATE_SCAN < = C.END_DT OR C.END_DT IS NULL))

  -BUT - now we have a society where people who have worked since the 1980s, the Cartesian join near the DATE_SCAN

  -really starts to make the system grind slowly through the scans.  Any suggestions?

  Hello

  According to you, the actual data, it could be much faster:

  WITH coverage AS

  (

  SELECT emp_id

  , DATE ' 1979-12-31' AS start_dt

  , start_dt - 1 AS end_dt

  Of emp_danger

  , DATE ' 9999-12-30' AS end_dt

  Of emp_danger

  UNION ALL

  SELECT emp_id

  start_dt

  , NVL (end_dt, DATE ' 9999-12-30') AS end_dt

  Of emp_qual

  WHERE qual_id IN ('A', 'B', 'C')

  )

  got_gap_length AS

  (

  SELECT emp_id

  , start_dt - 1 AS gap_end_dt

  , start_dt - (MAX (end_dt) OVER (PARTITION BY emp_id

  ORDER BY start_dt

  RANGE BETWEEN UNBOUNDED PRECEDING

  ET.5 PRECEDING

  )

  + 1

  ) AS gap_length

  Covered UNDER warranty

  )

  SELECT d.emp_id - or whatever it is you want the columns

  , g.gap_end_dt - (g.gap_length

  -1

  ) AS gap_start_dt

  g.gap_end_dt AS gap_end_dt

  OF got_gap_length g

  JOIN emp_danger d.emp_id d = g.emp_id

  AND d.start_dt<=>

  AND d.end_dt > = g.gap_end_dt - g.gap_length

  WHERE gap_length > 0

  ORDER BY emp_id

  gap_end_dt

  ;

  This produces a line of output for each group of consecutive days of risk not covered for each emp_id.  With your sample data:

  EMP_ID GAP_START_D GAP_END_DT

  ---------------------------------------- ----------- -----------

  3 January 2, 2013 January 2, 2013

  If you want to have a clean line of output for every non-covered day, he can adapt easily to the above query.

  Solomon and I seem to disagree on your needs.

• The analysis of the non-numeric characters in a string

  Hello

  I am communicating a robot to LabVIEW (2013) via TCP/IP and sockets. The robot is the server, and LV is the customer.

  I start with the target data in this format (in a string):

  "[0 ~ 100 ~ 0] ~ [0.96593 ~-0.25882 ~ 0 ~ 0] ~ [1 ~ 0 ~ 0 ~ 0] ~ [150 ~ 50]."

  [X, Y, Z], [Q1, Q2, Q3, Q4], [C1, C4, C6, Cx], [TCPVel, OrientVel] except replacement ',' (comma) with a ' ~ ' (tilde) because I load the target data in a spreadsheet which is a comma-delimited file.

  In LV, I take this string, the analysis of the chain and split individual items. I then pulled the singular elements as unique, 32-bit of real numbers. I take each one and convert them individually to a string, concatenate them and send them to the robot. The robot decompresses these raw bytes individually and converts them to a target of robot (position in space).

  I train (BT) check if the user has sent a bad character (non-digital) in the target data. Example of this is:

  [- 50 ~-150 ~ 0] ~ [0.96593 ~-0 ] [B2has5D882 ~ 0 ~ 0] ~ [1 ~-1 ~ 0 ~ 0] ~ [150 ~ 50]

  Now in BT, when I'm scanning the chain, these bad character becomes the entire element to zero and everything else then to zero as well. See attachment for example screen similar.

  My question is, my VI, I can analyze all non-numeric characters (that are inside the parentheses and characters that are NOT a ' ~ ' (tilde))? In this way, I can always get this item numbers and do not have this element or other items turn to zero?

  Thanks in advance for any help!

  Sorry for the question of the test

• accelerate the backup of data received through series

  Hello

  I hope you can give me some advice. So far, I have not found a solution.

  I have a sensor connected by USB-serial converter to the computer (COM 2). After the beginning of the measure, the sensor sends continuously data as a string. The sensor is able to operate at different speeds and it is controlled through strings sent to the device.

  Now, I have programmed a small piece of code to read and evaluate the data from the sensor. There is no problem while looking at live data in several locations. But as soon as I try to save the data, I have speed issues. The loop is not fast enough to receive the data, because it is provided by the sensor. Temporarily remove the plots and so on, don't help not, therefore the problem is data backup. As far as I know, I should use the tables that I did and I don't think that editing bays should be the bottleneck, because they should be able to manage data in general much faster.

  In the Hyperterminal with windows, the unit works fine.

  I use VISA series with a timeout of 2 s and a buffer of 128. Baud rate is set to 460800.
  The real VISA read command is set to read 50 bytes max or stop a tank of termination (line break).
  After initialization, and sending the command start for the sensor, the device starts to send its data...
  The different speeds are:
  1 - 4 strings per second
  2 - 10 per second
  3 - 100 per second
  4 - 500 per second

  Each line gets cut, evaluated and plotted. Each value is also stored in a table (which could be saved after the program stops).

  In the photo, I deleted several commands sent to the probe, because they are not relevant and it doesn't matter (of failure) if I remove them in the program or not. It goes the same for plots. After setting the device at the higher speed, the program fails, because there is more data than labview bed. (I have already said, that without the tables it works very well, I do not have it?).

  So, what can I do? I'm doing something completely stupid? Is there a faster way to collect data with labview? I mean, 500 HZ, which must be nothing.

  Thanks for your help.

  Kind regards

  You use insert into table with each iteration and forcing LabVIEW to keep reallocation memory for the berries. It is not very effective. Instead, I advise you to use the architecture of producer/consumer and transmit data back to the consumer loop where you write the data. Shift registers and who would skip all the functions to insert it in the table. You also use local variables and property nodes. Neither one of those who are very fast either. Can't tell from the picture why those are used. Also, consider using a structure of the event for these Booleans wired for the structures of the case. Do you really need those who questioned all the time and run the code with each iteration, or do you just need them to run once when the Boolean value changes?

• The analysis table of Boolean in FPGA

  Hi all

  Although I programmed in LabVIEW several times, I am quite a novice when it comes to programming on an FPGA, and I learned that I will (which, so far, has worked with little problem).  However, I have solved my most recent problem and more I read on the FPGA, less certain I am that what I try to do possible.

  The task is to read in a number of bits of the digital input/output lines of the FPGA and the analysis of these bits in specific words / "bytes."  For the application of the VI that I have attached, I rigged reading in a certain number of bits by providing three words of 26 bits (for a total of 78 bits) that have been defined on the front panel.  After providing the bits specified, I try to analyse the bit array in the specific words that are given by the following logic:

  1. find a start bit of 0 (false bit).

  2. once the start bit of 0 (false bit) is the word that seeks to analyze is the next 10 bits.

  3. after the start bit and 10-bit of data is a 1 (true bit) stop bit.

  4. Repeat steps 1-3, five times.

  The logic above, should be six words analyzed in total for the provided VI.  Unfortunately, I can not simply take 12 bits (1 start bit, 10 data bits, and 1 stop bit) at a time, as the number of bits of padding between successive words is variable.  The VI I provided is a version of how I proposed to perform the logic above, but I can not compile the project/VI, I get constantly mistakes "Tables to be fixed size."  To my knowledge, all the tables in the VI have been allocated in advance, and seems to be deterministic.

  If anyone has any suggestions as to why this VI is not compiled, I would greatly appreciate.  Thank you in advance for taking the time to look at it, and I look forward to resolving this issue.

  With gratitude,

  Gregory

  Unfortunately, you'll have to rework this VI to run on an FPGA.  You cannot move tables in memory in an FPGA the way you can on a PC.  You have an array of variable size as the exit to remove the table, because the entry of length is not fixed at compile time.  In addition, two-dimensional arrays are not allowed.  Remember when coding for an FPGA you actually write the material - each value in a table is basically a circuit (that's my oversimplified understanding).  The compiler cannot affect the right number of sons to carry a table if it cannot determine the size of the array.  The table is not in memory, so there is no way to reorder running.

  There are two ways you can work around this problem, which will require an iteration through each element of the input array.  You could use a FPGA FIFO and just put the values in the FIFO which are given (that is to say, in a loop until what you have touched a start bit, putting the next 10 values in the FIFO).  Then across the FIFO, possibly in a separate loop, read 10 bits at a time to get your words out of data.  Another approach is to reorganize the table as you go.  Keep track of the current location in the input array.  When you hit a start bit, away from the 10-bit (you may need to do this one at a time) to the current location in the input array, incrementing the current location every time.  When you have completed all entries, all data will be at the beginning of the table in units of 10 bits, which you can split out as needed.

• problem with the vista updates, dates back to December 2008

  In December 2008, I had remote access, now have broadband services. have family vista premium with service pack 1, the problem started when I tried to install the December 2008 windows updates. checked all updates essential etc. then let problem execution, not finished, then computer rebooted as it always does, is gone on the screen, then rebooted, saw the windows bar downstairs and then (as would normally go to LOG IN) it went to black screen and then off, the thing windows tried to start and check the disc and other programs of repair but kept saying could not start. Looked at this time comes to say has encountered an unknown error and could not fix, end was to use the F keys as an administrator login and do a system restore to 5 December and then worked well, have run the check disk and defrag and virus scans etc... now, my pc works fine, but I have not installed updates since December 2008, as know that it will happen if I do. However, I want to keep my vista up-to-date. I think that may be corruptions in the updates in a temporary folder somewhere, but don't know where it is. is - it there anyway to remove the files that can be corrupted or is there another solution, looked everywhere for answers in the forums and helpdesk there were several other people in the same question. My computer work fine, but I wonder if I will ever be able to install an update again. I have to be clear that I can run windows update without issue, it lists later and everything but when it's this thing to reboot it goes back to square one as shown above. Something in the updates is messing up my system and even widows classes as unknown error.

• Drive CD/DVD not visible in BIOS, Device Manager or Windows Explorer - only during the analysis of the system.

  Until a few days ago, this problem didn't exist - I know.  My CD/DVD drive is no longer recognized in Windows Explorer, BIOS or Device Manager.  It doesn't, however, appears briefly in Windows Explorer in the analysis of the security of the computer.  It allows to open/close, etc.  and when it is visible, I am able to open the drive and see the contents of the CD.  Then it disappears again.  The light flashes indicating that he works and I can hear it trying to read the CD.  I uninstalled iTunes because I read somewhere that this may have been the issue - but that didn't work.  I tried the system restore, registry cleaners, removal of upper/lower case filters from the registry, used the program Fixit found on the site Web of Microsofts etc and still no luck.  Any ideas?  The computer is a gateway SX2850 (?) with Windows 7 Home Premium installed.

  Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
  Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
  RESTART this will refresh the default driver stack. Even if the reader does not appear to continue

  Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
  manufacturer of device to see if there is a firmware or drivers for your drive if necessary.
