Day Before Data Collection: Charge All Device

Note: Prior to beginning any data collect, you need to have setup and installed software for all devices.

  • To be safe, make sure the Wockets are charging for at least 5 hours before a test.
  • Before each test, the voice recorder should be placed in cradle with USB attached to the Dell mini laptop, this will charge the voice recorder.
  • Make sure all devices are fully charged including:
    • Phone: plugged into the USB cable attached to USB hub number 1
    • Wockets: One wocket goes into USB hub number 1, the remaining four are plugged into the dedicated USB hub
    • Dell Mini and Oxycon laptops: Connected to power supply cord
    • Oxycon batteries: Li-Ion Battery Charger connected to power strip
    • Actigraphs (2): GT3X plugged into the top USB port on the right side of the Oxycon laptop. GT1M is attached to the bottom USB port
    • Sensewear: Connected to USB Hub 2
    • GPS: Power cord attached to the power strip
    • Zephyr: Placed in cradle attached to the USB Hub 2
    • Voice Recorder: Placed in cradle attached to USB Hub 1
    • RTI batteries: AA Batteries in the battery charger plugged into the wall in clinic office
    • Columbia batteries are not rechargeable.


Day of Data Collection: Prior to Subject Arrival


1. Check Power Settings on the phone and Volume Level
  • Click on the start menu. Go to Settings.

  • Under Advanced settings, uncheck Turn off device if not used for both external and battery power. Check turn off backlight for both external and battery power.

ppc_power_2.jpg

  • Check the volume on the phone that it is maximized and not muted. If something goes wrong during the test, the phone will start beeping. In this case, you can stop the test and inspect the setup.

2. Check Power Settings on the PC.
  • In your control panel, go to power settings.
  • Make sure that your PC is set to "always on" but that the display shuts off after 5 minutes when the lid is closed and when on battery power. The kind of options that you see vary from one PC to another.
  • Timezone and correct daylight savings time should be checked as well.


3. Synchronize PC Clocks.
  • For each of the PCs involved in the data collection (e.g. Oxycon PC, MITes PC), you need to synchronize their clocks over the internet with a nearby time server. This is done by executing on each PC, the Wockets Time Synchronizer application.
    • a. Launch the Time Synchronizer Application and make sure that the PC internet connection is ON.
    • b. Press the "Synchronize" button.
    • c. If the PC was successfully synchronized with the server, you will see a message with the time synchronization parameters.
    • d. If the PC was not synchronized with the server, you will see a timeout error message or server not found message.
    • e. If PC was synchronized, visually inspect the the "Local Clock Offset" parameter shown on the screen.

    • If the "Local Clock Offset" value is within +-1000 ms. No further action is required.
    • If it is not, you need to wait 5 seconds and press the "Synchronize" button again.

    • f. Once you finish synchronizing the time, press "Quit" to exit the application.
    • g. It is recommended that you execute the application on the PCs at the same time and before each test.
    • h. Once you have done that visually check if there is any drift between the clocks of the PCs. If they are within 1second, no further action is required. Otherwise, try to synchronize them again.

    • Visually confirm that the 3 computers are synced in time upto +-1000ms. Check times in all PCs to confirm that the PCs are synced by clicking on the PC clock (bottom right corner).


4. Synchronize Mobile Clock
  • You need to synchronize the phone clock over the internet with a nearby time server. This is done by executing on the phone, the Wockets Time Synchronizer application. This application is installed at the same time than the Wockets application on the phone.
  • Before running the phone Synchronizer application, you need to unplug the phone from the computer and turn on the phone WiFi.
  • Once the phone WiFi is on, execute the the Wockets Time Synchronizer application.
  • To run the synchronizer application on the phone. Go to Programs and Run TimeSync Application.
phone-wockets.gif
  • Follow the steps from the PC Synchronizer Application from (b) to (f).
  • The application will synchronize the phone’s clock when it is connected to the WiFi, as long as the internet connection is working properly.
  • Again, visually inspect the phone and the PC clocks, if they are within 1-2 seconds, no further action is required. Otherwise, try to synchronize them again.


5. Print the notes file.
  • The [name]notes.doc file should have any special notes about the session. All special comments related abnormalities in the session or sensor data should be recorded in this file. This file is where someone might look for clues if they get a strange result when analyzing the data in the future.
  • To simplify the notation process, print a blank copy of the file before the session starts.
  • When you finish the session, copy the notes to the electronic version of the file. This text file is for human consumption only and can be in whatever format you see fit.
  • An blank notes file format can be downloaded from the following link:

Synchronization Time
    • Make sure you write it according to the synchronized time from the PC. If you use the wockets phone or a wrist watch for synchronizing the time, please indicate it on the notes file. If you use your wrist watch to write down the notes time, make sure your wrist watch is synchronized with the PC clock.

Sensor Placement
    • Put all the sensors on the subject's body as indicated on the Sensor Placement Wiki Page. When you finish placing all the sensors, continue to the next step. To access the Sensor Placement wiki, click on the hypertext here.

Sensors Connection
    • MITes (See pdf document)

    • Wockets
        • To go to wockets folder, click on the "Wockets" application and choose the "Data Logger" option. And then choose, the "Stanford Protocol"

phone-wockets.gif
Wockets_DataLogger.JPG

    • After, choose the sensor set that you will be using in the data collection. For example: "Stanford Set 1". After the software loads, the phone will try to connect to the sensors. If the sensors are loaded properly, you will see the accelerometer signals plotting on the screen.

Wockets_Graph.JPG

    • If a sensor cannot connect, you will see the corresponding sensor icon highlighted in red. The Codes near to the icons indicate their IDs corresponding to the last digit of the sensor mac-address (to check the ID, visually check the label attached to the sensor).

ppc_wockets_api_screen_5.jpg

    • Turn off the plotting feature in the software. Among other things, the software provides the option to turn plotting on and off. Turning the plotting off makes the application less computationally intensive and allows it to run more smoothly. To turn the plotting off do the following:
          • Click the "options" button on the lower menu bar. Then, a window will pop up, click the "Data" option and, then, "uncheck" the plotting options. This will disable the plotting and, from this point, you will see that the graphing functionality will be stopped.

Day of Data Collection: Immediately After Subject Leaves


Aggregate Data


    • 1. Once the session directory ("...\session<date>") is created following the steps mentioned above, you need to copy the data collected from all the devices into this directory. Here the description of the format to use.

    • 2 . Copy the sensor files from all devices into this directory using the specified naming conventions and following steps:

    • MITes
      • Copy the MITes data into the " ...\<session><date>\mites " directory.

    • Wockets
      • Copy the wockets data from the phone into the wockets directory " ...\<session><date>\wockets ". You can this operation following the steps below:
        • On the phone, the wockets data will be stored in a folder on your storage card under " /Internal Storage/Wockets/ ". The folder is named Session<date><time> .
        • Connect the phone to the computer with the supplied USB cable. The Microsoft Active Sync box will open. Click "Explore" and navigate to the " device\Internal Storage\Wockets ".
        • Copy the session folder and paste it in the session folder where you plan to storage the aggregated data " ...\<session><date>\Session<date><time> ".
        • Rename the pasted wockets session folder to " wockets ".
        • As a result, you should have the following folder structure:
          • " ...\<session><date>\wockets "
          • " ...\<session><date>\wockets\data "
          • " ...\<session><date>\wockets\data\log "
          • " ...\<session><date>\wockets\data\raw "
    • Oxycon
      • Now go into patient data and load the current patient. On the bottom panel click Reset to remove all the tests from the right hand table. In the test directory the last 2 entries should correspond to the PC saved data and the flash disk data, respectively, saved as 2 different tests. However, the flash data might not be the test right after the PC data if you've run and saved multiple tests without saving any of the flash data. It might be easier to keep track of, if you save the flash data immediately after running a test. Click the right arrow to select that test to be output by the report. Only output 1 test at a time (meaning reset after printing a report).
      • Generate the output files, save them and along with the raw oxycon data files from the PC and from the flash (including CPX file) into the " ...\session<date>\othersensors " directory.
      • If the " othersensors " directory doesn't exist, create it under the " session<date> " folder.

    • Sensewear
      • Copy the sensewear.xls file into the " ...\session<date>\othersensors ".
      • Once you copy it, open it with excel.
      • Convert the file to " .csv " format.
        • In excel, click on the sheet named "data".
        • In excel, go to " File->Save As " options. If you are using Office 2007, click on " Other Formats ".
        • In the " Save As Type " option, select " CSV(MS-DOS) ".
        • A window will pop up indicating "the selected file type doesn't support workbooks that contain multiple sheets". You will be prompted to choose if you want to save only the active sheet. Click "OK" .
        • Another window will pop up indicating that "the .csv file may contain features that are not compatible with CSV(MS-DOS)" and it will ask you if you want to keep the workbook in this format. Click "Yes" .
        • Exit excel. It will prompt you if you want to "Save" the changes to the .csv file. Click "NO" . If you click "Yes", it will pop up the same windows that you saw in previous steps.
      • Verify that the *-Sensewear.csv" file was created. The file should exits in the " ...\session<date>\othersensors " directory.

    • Other Sensors
      • Next, copy the sensor files from all other devices into this directory using the specified naming conventions.



    • Audio Annotations
      • Make sure that the " annotation " folder is under the " session<date> " directory. The folder structure should look like: " ...\session<date>\annotation"

    • 3. Add any notes you have for the experiment by manually editing the [name]-notes.doc file. When you finish editing it, copy it to the "...\session<date>" directory. The folder structure should look like: " ...\session<date>\[name]notes.doc ".

    • 4. You now have all the data in one place, Zip the " ...\session<date> " directory . Copy the zip file to another location . This is a temporary backup, just in case.



Important General Reminders


    • Restarting the software for devices once the data collection procedures have started is potentially problematic for the automatic conversion software. If this happens, most likely some type of manual effort to merge files will be required. Therefore, please notate this carefully. If it happens with the Oxycon, we will not have a way to sync the second file except through visual inspection. Restarting a device (other than the Oxycon) should usually be ok, but if a software program must be shutdown, the startup procedure probably needs to be redone and special notes made in the notes.txt file.

    • Running an overnight test when daylight savings time changes should be avoided.

    • Extra attention needs to be paid to device settings and datasets collected immediately after a daylight savings time change to ensure they are properly in sync.

    • No files should be manually edited except the [name]-notes.doc file.
