Configuring the Software

Setting Up the Software to Detect Your Hardware Model

You will need to follow the instructions below after your initial installation and

after each software upgrade.

If Physiolab is not already running, click on the Physiolab desktop icon toget to the opening window. Click Run Sessionto bring up the Select

Application window.IMPORTANT:Click on the drop-down arrow in theHardware Type boxand select the type ofJ&J device that you

have connected. (TheUSE3 softwaresupports many differenthardware devices so itis important that youhave selected thespecific hardware thatyou are using.) In theapplication list, clickon the name of theapplicationyou plan to

run. Next click Setup.

In the Hardware Setupwindow, be sure that thecorrect port (COM or USB)that you used to connectyour device is selected. Ifyou are using a COM portconnection, be sure theCOM port numbermatches the one you are

using. NOTE: Thiswindow displays the application date and currently installed version date (MBPVersion).

Eliminating Electrical Line Frequency Noise

In North America the electrical line frequency is 60Hz, but in many countries linefrequency is 50 Hz. The notch filter is defaulted to 60Hz so, if you live in a

7/25/2019 Isolated i330

8/65


country where the electrical line frequency is 50 Hz, you will need to configurethe software for your area. In the Hardware Setup window (pictured above)check to see that the line frequency for your area is selected in the Notch filterbox. If the setting is incorrect you will see noise appearing as spikes at regularfrequencies in the signal FFT displays. (For additional information please see the

Artifact Detection section in your Hardware Manual.)

Setting Up Dual Screen Mode

Many newer laptop computers can support a second monitor with two differentsimultaneous displays. Many desktop computers can be upgraded to thiscapability with the addition of a dual-monitor video card available at mostcomputer stores.

The optional Dual Screen Mode feature allows you to have a therapist screenand a separate client screen with monitor and control functions on therapistscreen #1 and a simple feedback display or game on client screen #2.

Set-Up and Testing of Dual Monitor Displays

If you have this capability on your computer, it can be turned on as follows:Right-click on the desktop, then click Properties, then Settings. Right-click on2, then clickAttached. (A check mark should appear next to Attached.) Checkthe box labeled Extend my Windows Desktop. Set the screen resolution to thesame resolution as primary screen #1, preferably 1024x768. Please see yourcomputer owners manual for help with this set-up.

When this is set up properly, your computer should boot-up with your normal

desktop on Monitor #1 and the desktop background picture without any icons onMonitor #2. You should be able to run USE3 software with dual displays. If youhave trouble getting the dual monitor desktop function working, please check withyour computer supplier.

Using Dual Display Mode with USE3 Physiolab Software

The USE3 software supports dual monitors on specific screens that are markedin the screen name with letter D or Dual. To enable this feature in USE3, fromthe USE-3 Sign-On Screen click on Optionsand check mark Dual. Do not dothis unless you are sure dual monitor mode with extended desktop is working onyour computer.

Click the Dual Display Icon to see a list of all available Dual Screen Displaysin an application, To select a feedback screen to appear on a second monitor,click on a dual screen display name and click APPLY.

The second monitor display will have a feedback only with no controls or mousefunctions. All the settings on the feedback screen will be slaved to a display on

7/25/2019 Isolated i330

9/65


Monitor #1. (The exception to this is Windows Media Player used as a feedbackscreen.)

In Dual Mode on laptop computers you may notice a speed reduction when thescreen is updating. This is due to your computers display driver limitations. It

should not affect feedback.

In most applications the feedback display on Monitor #2 will also be shown onMonitor #1 as a smaller sub-display. To make changes in the feedback display,you need to highlight the display and signal on Monitor #1 and use the left-handtool bar to make changes. These changes will be reflected in the feedbackdisplay on Monitor #2.

Below is a list of several recommended video cards which provide the dualdisplay mode feature on desktop PCs that have an AGP video card slot. Checkwith your computer supplier or on-line suppliers such as compuplus.com,

compuvest.com, Spartan Technologies, etc.

Overview of the Software Interface

This section is an overview of the toolbars and signal controls common to allPhysiolab applications.

Starting an Application

To begin running an application click on the USE3 Physiolab icon fromyour desktop. The program will load to the Main Menu.

SELECT CLIENT

RUN SESSION

MANAGE DATA

EXIT

Click on Select Client. Select a client name in the Select Client Window.Recorded session data will be saved under this client name. Click the Selectbutton. If you skip this step, you will be prompted later to select a client if yourecord data. (For information on adding new clients, editing, and deleting clientrecords, please see the Adding and Deleting Client Information section.)

Next, click on Run Session. This will bring up the Select Application window.

Make sure that the J&Jdevicethat you haveconnected to yourcomputer is selected inthe Hardware Typedrop-down box. Eachhardware type has itsown unique applicationlist. Click on the name ofthe applicationthat youwish to run. Click Start.

If you receive an errormessage, click OK,check the connection toyour computer, thenretry. If you have troublestarting a session,please refer to the

7/25/2019 Isolated i330

11/65


Troubleshooting section in your Hardware Guide.IMPORTANT:Once you have started an application you must exit it using thearrow in the lower left-hand corner, NOT the red X in the upper right-hand corner.

Ensuring a Good Connection

In every application session, the first screen you will see is the Sensor TestScreen.Hook up the sensors using the picture as a guide. Please refer also toyour Hardware Guide for information on cable/electrode configurations for yourdevice and connection tips for different modalities.

The Sensor Test Screen displays the impedance of each EMG/ECG/EEGelectrode as a bar graph. The digital bar values are in K Ohms (K=1000 Ohms).J&Js impedance testing feature is important because it enables you to determinethe quality of your signals. High impedance levels allow environmental electricalnoise to contaminate your signals. Values in the green range indicate optimal

functioning, yellow indicates marginal functioning and red indicates that theconnection is inadequate and needs attention. (Please see the ImpedanceTesting section of your Hardware Guide.) The bar colors are intended asguidelines only. The values needed to ensure good signals are dependent uponthe amount of electrical noise in your location and the signal level of interest.(For more information please see the Artifact Detection section in yourHardware Guide.)

Signal bars for modalities other than EMG/ECG/EEG display green for normaloperation, yellow for needing adjustment, and red for disconnected or broken.

For devices powered by batteries, a digital battery indicator display near thebottom of this screen tests and displays the remaining voltage.

Checking For Good Signal Data

Click onCheck Signals. This screen displays all signals available in theapplication and currently being acquired so that you can inspect them to verifythat they appear in normal ranges. It is not intended for feedback. In

Applications with EMG or ECG, it includes a frequency spectrum (FFT) displaywhich is particularly useful for detecting environmental electrical noise. (Pleasesee the Artifact Detection section in your Hardware Guide.) A Check Signals 2screen provides a screen without the FFT display for slower computers.

The Sensor Test and Check Signals screens are unique to J&J and are designedto ensure the quality of your data. You should check these screens each timeyou start an application.

Toolbars Overview

The top Screen Select Toolbarprovides buttons for choosing a specific displayscreen. The left edge Signal Control Toolbarprovides buttons to change thedisplay characteristics. The Session Control Toolbarat the bottom of yourscreen provides controls for specifying tasks, recording data, marking events inthe data, and for invoking various screen features such as screen freeze andsweep reset. The Session Status Bar,located below the Session Control Bar,indicates elapsed and remaining times for both the current task and the entiresession. The Task Progress Barlocated above the Session Control Barindicates progress through one or more preset timed task intervals. It is agraphical representation of the numbers in the Session Status Bar.

You can increase display screen area and minimizedistraction by hiding toolbars that you are not using. Simplyclick View, then click next to the names of the toolbars youwish to hide. This will remove the checkmark next to thetoolbar name and make the toolbar disappear from view.You can retrieve toolbars individually by again clickingView, then clicking the names of the toolbars you wish toreinstate OR you can retrieve all of the toolbars at once byclickingAl l Bars On.

Selecting Display Screens

The top Screen Select Toolbar lists all of the available display screens in an

application. Use this toolbar to select a specific display screen.

The screen button which is highlighted shows the name of the current screenbeing displayed. Most of the top buttons have pull down menus (as shownabove) of alternate screen choices. Clicking on the down arrow next to thescreen name activates this pull down menu. Whenever you select a screen fromthe pull down menu, it is assigned to the top menu button. This ensures thatyour favorite screen in each menu group will be only one click away. On slowercomputers, click on the drop-down arrow and hold it down while mousing overthe drop-down menu area, if the drop-down menu doesnt at first appear.

You can loop through a single task or through a series of tasks a specified

number of times. Check Loopthen select the name of the task that you wish tohave as the start of your loop. You may only loop back to tasks in the list that areabove the currently selected task. (NOTE: You will need to click the drop-downarrow and the tiny scrollbars to see all the tasks in the list.)Type in a Number of Loopsto indicate the number of times you want theprogram to loop through the tasks before it moves beyond the loop to the nexttask in the list.

If Pause Record On Startis unchecked, recording will automatically start at thebeginning of the task and continue for the number of seconds you specify in thetop rightTask Record Timebox.

You may set a pause at the beginning of the task and let the task autorun so thatthe task begins recording after the time interval that you specify. Check PauseRecord On Startand specify a number of seconds in the Pause and Text Timebox in the middle of the window. If you wish to manually start each task, you willwant to specify a long pause time at the beginning of each task. When you runthe task, click the Pause ON/OFFbutton to manually override the pause andbegin the task.

Programmed Tasks: Instructional Text Boxes

If you wish for a text box with instructions to appear at the beginning of the task,

you can select one of the text instruction files in the Select Namedrop-downbox. Click Test Textto position and resize the window and to view the text.USE3 Physiolab comes with a large selection of instruction text files but, if youwish to add your own, you can create text files and save them into theC:\Program Files\J&J Engineering\Physiolab\Text folder. These files must be in.rtffile format and must have unique file names. If you wish to change thewording of J&Js instruction files, click Edit Textafter selecting the filename thatyou wish to edit. Be sure to click Save Asand change the file name so that yourcustomized files will not be overwritten during software updates.

Check End text window on pause or record clickif you wish the test

instruction window to close when recording begins (either an autorun pausetimes out or you click Pause ON/OFF to manually override the pause).If End text window on pause or record cl ickis unchecked the text window willappear during the entire length of the task. NOTE:You must click Test Text andresize the window in order for the text to display properly.

If you wish a task to be instructional only, with no data recording, check theRecord Offbox.

Programmed Tasks: Audio Files

USE3 Physiolab comes with many audio files which you may elect to play whenthe task starts, when recording starts or at the end of the task. Text WindowStartfiles are alert beeps or verbal instructions up to one minute in length. To

play an audio file at the beginning of the task, check Text Window Start andselect an audio file name in the drop-down box to the right.Record Start audio files may be used as alert tones or as stressors (i.e. babycrying) in a stress profile task. To play an audio file at the beginning of recording,check Record Start and choose an audio file name in the drop down list.

If Pause Record on Start is checked, you may specify both Text Window andRecord Start sounds since the text window will appear at the beginning of thetask and recording will start later. If Pause Record on Start is unchecked, thenthe text window will display at the same time that recording starts and only theText Window Start audio file will be heard.

Task Endshould be used with care. You may not have both an ending audio filefor the current task and a beginning audio file for the following task. If youspecify both an ending sound for the current task and a beginning sound for thefollowing task, then the ending sound file will be overriden by the following starttask audio file.

The easiest way to become familiar with USE3 Physiolab audio files is to go tothe C:\Program Files\J&J Engineering\Physiolab\Sounds folder and double-clickon each WAV format audio file to play it. The subfolders are sounds that areused in game feedback screens and are not available as task sounds. You may

add your own files to the Sounds folder. They must be WAV format audio filesand have unique names so that they will not be overwritten during softwareupgrades.

Creating Your Own Programmed Tasks

Start by clicking on the Select Task iconto open the Programmed TaskSchedule window. Click Edit Mode On. Click in the top Select Scheduleboxand type a new unique name for your task. (Naming Tips: This name cannot beedited so choose carefully. If you want a particular Schedule to appear at the topof the list keep in mind that schedule names are arranged alpha-numerically in

ascending order.) ClickAdd Task. Then follow the same process for each taskas outlined in the section on Customizing Programmed Tasks above. If you wishto add a new task in the middle of the task list, click on an existing task nameabove which you want the new task to appear. ClickInsert Taskand proceed tocreate the task in the same manner as for adding a new task.

After you have specified settings for each task, click OKin the middle of the TaskProperties window. When you have finished setting up all tasks, clickAdd AsNew Schedulein the Programmed Task Schedule window to save your settings.

Saving Programmed Tasks

After you finish modifying or creating each task you must click OK in the upperportion of the Task Properties box. If you click Cancel or close the window withthe X your settings will be lost. If you are finished modifying tasks for an existing

task schedule, click Update Schedule. If you are finished adding new tasks to anew Task Schedule, click Add As New Scheduleat the bottom of theProgrammed Task Schedule window.

The settings for Task Schedules will be lost when you upgrade your softwaresince they are part of the updated application. You can keep your current (older)version of the application with your customized tasks by going to the C:\ProgramFiles\J&J Engineering\Physiolab folder and renaming the .mdbfile for eachapplication you wish to save. These renamed customized applications will be notbe updated. When you start USE3 Physiolab and click Run Session, twoidentical application names will appear in the application list. Find the one with

your customized tasks and run that one until you have time to customize yournewer version of the software.

We recommend that you print screen captures of Task Properties windows for allof your customized tasks so that you can re-create them in the upgradedsoftware. (Instructions: Open the Task Properties window for each task and click

Al t+Print Screenon your keyboard, then open Start> Programs> Accessories> Paint. In the Paint programclick Edit, then Paste. Click File, then Print.)

Saving Session Data & Verifying Client Names

Youmay find that your sample rate is too high or too low to create a meaningful chart.You can re-send the report to Excel at a different sample rate using the ExcelReport button, resave it to a new filename, and re-chart it using the Excel ChartWizard.

You can save your Excel report using the File>Save menu commands and/orprint out your report using the using the File>Print commands in the Excel menubar.

Exporting Data to Excel or Your Own DatabaseExporting data does not affect the original data record. It only exports copies ofthe data. To export data, first follow the instructions for selecting session dataunder the Managing Data section above. Then click Export.

In the right side of the Export Dialog window, uncheck any information you do notwish to include. In the Update drop-down box, choose the update rate, which isthe averaging interval time in seconds (decreasing the rate reduces file size andmakes charting the data more feasible). Select either Average Only or BasicStatistic (described in the Quick Reports section). If you dont want to export allof the signals, highlight individual signals and move them into the Saved Signals

If you are using your own database program, use the instructions supplied withthat program for importing and manipulating data.

Automatical ly Generating Fi lenames for Export Data

Once you have used Change File to specify an initial target location and

filename, you can let Physiolab automatically generate a new filename andexport to your initially specified location by default each time you export data.When you click Exportthe next time, the target location and filename from yourlast export will be used again unless you specify something different. It isimportant to selectAuto Increment in the Export Dialog window or the exporteddata will overwrite the previously saved file with the same filename. When AutoIncrement is checked, the number in the Auto Increment textbox will be added toyour initial filename. When you click OKat the bottom of the Export Dialogwindow, the data will be exported and the Auto Increment number will increaseby one integer. You can start Auto Increment over at zero or at any othernumber you choose by typing that number in the textbox to the right of the Auto

Increment check box.

Even with Auto Increment selected, you always have the option of manuallyspecifying a unique filename by clicking on the Change File button, typing yournew filename, then clicking Open. The number in the Auto Increment textbox willbe added to your manually typed filename when you click OK in the ExportDialog window to export your data. This new filename will become the newdefault template filename unless you change it back.

To automatically generate data export filenames using a client name as thefilename template, both the Use client name as Templateand theAuto

Increment checkboxes must be checked. Even if you have exported data beforeusing Change File to specify a location, you must specify an initial targetlocation again when switching to using the client name as a filename template.When Use client name as a template is checked, the Change File buttonopens a window to select a file export location only, without a textbox forspecifying a filename. Browse to the data destination folder of your choice, thenclick OKto confirm your target location and close the window. Click OK in theExport Dialog window to export your data. For future data exports, once youhave selected a data session and clicked Export, your target location andfilename will be automatically set and you will need to simply click OK to export.

Archiving Sess ion Data

All patient data is saved into the same Physiolab data.mdb file. When you havestored gigabyte of data, you will start getting messages suggesting that youarchive files. It is important to respond to these prompts and archive data sinceyou will not be able to access session data if the 1 gigabyte maximum databasesize is reached.To archive data, click Manage Data on the main entry menu, then clickArchive.

In the Archiving window, select a client alias name in the Main Database drop-down box. Select an application that has data for the client in the top drop-downbox. To select a target folder location for your archived files, click the smallbutton to the right of the Archive textbox. Either select an archive file name in the

Open window (if you have previously archived data) or browse to the folderlocation where you wish to create a new archive, type a new name in the Filename box, and click Open. You can choose to have a separate database file foreach client or you can archive files by time period (quarterly, half-yearly, etc.)

Back in the Archiving window, click on the date of a session in the list to the left,then click the right arrow to move it into the list of files to be archived. You canselect and move all files in the list or you can pick and choose sessions byholding down the Cntl key while clicking on those you wish to archive. Finally,click Compact Databasesto free up space in the Physiolab database, confirmby clicking Yes, and click Closeto exit the window.

If you wish to copy a file into a new data location, while leaving the original file inplace, follow the procedure for archiving files, but click the Copy dot before youclick the right arrow to move files into the right side of the Archiving window (Thisdoes not free up space in the data.mdb file). Click Close to exit the window.

At any time you can move archived files back into the original Physiolabdatabase to view them. Follow the same procedure for archiving files, but select

Adding and Deleting Client Information

To add a new client, on the main menu click Select Client,then click New.

Enter the new clients information. In the top textbox you have a choice of lettingthe program generate an alias name by leaving the box blank or of entering yourown alias name. Automatically generated alias names consist of the first twoletters of the last name followed by the first two letters of the first name. If twoclients have similar names so that identical aliases are generated, the programwill add a number after the duplicate alias to differentiate them. The alias namewill be generated when you exit the window by clicking OK.

SELECT CLIENT

To edit a client record, clickSelect Client as above, then click Edit. Modify theclient information as desired, then click OK.

To delete a client including all session data for that client: On the mainPhysiolab entry window clickSelect Client, highlight the client alias name, thenclick Delete. Click Yes at the warning prompt to delete the record.It is a good idea to click Edit to verify that you have the correct client namebefore deleting client records.

Overview of Screens and Displays

At the top of the session window in each application is a Select Screen Barwithdrop down lists of screen choices and hot key buttonsthat can change toprovide a quick link to the most recently selected screen in each list.

Each Screen may contain a single display which fills the entire window ormultiple displays tiled within the window. A good example of a tiled multi-displayscreen is the Check Signals Screen in every application. Below is an examplefrom the C2 EMG Application:

An individual display within the window can be selected by clicking on it and theZoom button can be used to fill the entire window with the selected display.

Each display may contain a single signal or multiple signals. By the light bluehighlight color surrounding it, you can see that the FFT_EMG A N display hasbeen selected. Since there is only one signal reflected in this display, selectingthe display also selects the signal, which can then be modified using the SignalControl Bar. (See Modifying Signals). The signals in FFT_EMG A N andFFT_EMG B N look quite different because they have been individually selectedand their scales modified independently with gain and sweep speed controls.

7/25/2019 Isolated i330

33/65


The SR-C and TEMP-C displays above each contain multiple signals sharing thesame space in a single line graph. Since these signals are of the same type andshare the same scale, the Signal Control Bar buttons will modify all of the signalsin these types of displays together. For example, if the SR-C display wereselected and the Gain Up button were clicked, gain would increase for both

signals in the display. Multiple signals can also share space in scrolling charts.

In other multiple signal displays, signals of different types can share the samespace in a single line graph or chart. Since only one scale for one signal at atime may appear in this type of display, you can click on a signal name to changethe display scale so that it matches the selected signal. Notice in the examplebelow that the HR signal has been selected, and that the scale to the left is inbeats per minute to match the selected signal. Only the selected signal will bemodified by the Signal Control Bar buttons. For example, to select and modify theResp1 signal below, you would click on the small blue box next to Resp 1. Notethat the second respiration channel is not being used, but the Resp 2 signal

name is listed to show it is available. If a signal is not being used, as in theexample below, or if it is accidentally adjusted off of the screen with the SignalUp/Down buttons, the signal is still present scrolling along the edge of the displayso that you can locate it. In the example below, the Resp 2 signal is present as atiny red square just under the Resp 2 name.

In contrast to this display, in displays with the same kinds of signals sharing thesame vertical and horizontal scales (as in the SR-C and TEMP-C examplesabove), individual signal names are not clickable and signals cannot bemodified individually.

In still another type of multiple signal display, each signal has its own line graph,with the graphs stacked parallel to each other and a common time scale alongthe bottom. The EMG A N and EMG B N signal graphs in the C2 EMG

Application Check Signals Screen above are considered to be a single stackedgraph display. Clicking on either graph will highlight both, and the Signal ControlBar buttons will modify both signals together.

7/25/2019 Isolated i330

34/65


In contrast to this notice the EMG A-N and ECG B (Raw) displays below whichare completely separate displays with independent vertical and horizontal scales.

The Resp1 + Resp 2 display below is a slightly different variation of a stackedgraph display in which the time scale is shared so that the sweep speed buttons

will affect both signals, but the vertical scales are independent so individualsignals may be selected and Signal Up/Down and Gain Up/Down controls areapplied separately for each signal.

In the above overview of screens, displays and the signal configurations they cancontain, you have seen line graph displays, FFT displays and, in the screenimmediately above, a bar graph display. The next section provides an overviewof these display types plus the other display types you will encounter inPhysiolab.

For detailed descriptions of the Sensor Testand Check Signalsscreens,please see the Ensuring a Good Connection and Checking for Good SignalData in the Overview of the Software Interface section.

Display Types

The following display types may fill an entire screen or may be tiled together inany combination, depending upon screen space and the usefulness of correlatingspecific displays together. The same display type may have different signal,background and fill colors within different screens and/or in different applications.

Zooming In

Any of the displays described below may be selected and the Zoom button usedto fill the entire screen with the selected display for focused feedback.

Line Graphs

Line graphs emulate an oscilloscope-type display, with one or more signalsscrolling left to right. Since full descriptions were made of several types of linegraphs above, a brief summary of line graph types follows:

1. Single line graph with multiple signals sharing the same spacea. If all signals are the same modality with vertical and horizontal

scales common to all signals, signal names are not clickable andSignal Control Bar buttons adjust all signals together.

b. If signals are for different modalities with different scales, signalnames are clickable and signals are adjusted individually.

2. Stacked parallel line graphs sharing a common time scale, with a singlesignal in each

a. If signals are for the same modality so that the vertical scales arethe same and the training purpose is to cause the signals to movein the same direction, signal names are not clickable and SignalControl Bar buttons adjust all signals together.

b. If signals are for the same modality but the training purpose is tocause signals to move in opposite directions or the signals may bemonitoring two different individuals, signal names are clickable andthe signals are adjusted separately

c. If signals are for different modalities with different scales, signalnames are clickable and signals are adjusted individually

Pattern Displays

A pattern display is a special type of line graph that contains a Pattern Signal.The Pattern Signal does not reflect physiology but, instead, provides a guide with

fully adjustable parameters set by the clinician. Sharing the space in the graphwith the Pattern Signal is a signal reflecting physiology. The goal is for theclient/patient to modify his/her physiology to match the pattern signal as closelyas possible. An example of a pattern display is the Breathing Patterndisplaymore fully described later in the Respiration Displays section.

7/25/2019 Isolated i330

36/65


Ghost Displays

The Ghost Display is another specialtype of line graph, which contains asingle signal. With each signal sweepacross the screen, the previous sweep

fades but remains visible forcomparison with the new brighter signal

sweep. You can see in the example below that multiple sweeps remain visible forcomparison across time.

Scrolling Chart Displays

Useful for showing trends over time, Chart Displays have a diamond-shapedtracer to the right which draws the signal as it scrolls to the left emulating atraditional paper chart. Though the signals scroll in the opposite direction as linegraphs, the oldest signals appear to the left, with the most recent signals to the

right, consistent with line graph displays. As with line displays, a chart displaycan contain a single chart with a single signal, multiple signals within a singlechart, with or without fill colors, or stacked signal charts as in a History Chartexample shown below. All signals share a common time scale so that FasterGraph/Slower Graph buttons adjust all signals simultaneously. Vertical scales areindividually adjustable.

Fill Graphs

Fill colors are used in both line graphs and in scrolling charts as shown above.The fill colors used above are used to give the signal emphasis, especially in

7/25/2019 Isolated i330

37/65


reference to zero or some lower point in the scale. Fill colors can also be usedas color rewards for achieving threshold goals as in the Threshold Up, ThresholdDown, and Threshold Up/Down Displays below. The Threshold Up displayprovides a color reward when a threshold is exceeded. The Threshold Downdisplay is useful when the goal is to modify physiology by bringing the signal

down. Fill and background colors may vary in different screens and applications.

Threshold Up Threshold Down

Threshold Up and DownA dual-purpose display, which provides different fill colors above and below the

threshold line. It is structured like the Zero Point Fill Display pictured belowexcept that the reference point for the change colors is the threshold line insteadof zero. It can be used as either a threshold up or threshold down display, withthe goal area color providing a reward and the out-of-goal area color providing areminder.

Adjusting Thresholds

The threshold signal name is listed in the display but you cannot click on thissignal name to select it because none of the Signal Control Bar buttons apply tothe threshold signal except the Adjust Threshold button. In displays withthresholds, AutoThreshold is defaulted to ON so that it is at a known visible pointin the display. If you wish to disable AutoThreshold and manually set your own

threshold, click on theAdjust Thresholdbutton to bring up the ThresholdControl window. Next click on the check mark next to Enable Auto Threshold inorder to turn the automatic threshold adjustment feature OFF. Click on theDown/Up arrows next to the Level box or type a numerical scale value in thebox. The threshold line will move to point on the scale that you specify. Closethe control box by clicking on the small x. If you want to turn the Auto Thresholdfeature back on, click on the Adjust Threshold button, click in the emptycheckbox next to Enable Auto Threshold, then click on the xto close the pop-up window.

Another way to adjust the threshold is to drag and drop the threshold lineonthe display screen. First put the cursor in the display area and click the mouseonce to activate the drag-and-drop feature. Now as you move the cursor over thethreshold line the arrow will turn into a hand. When the hand appears, click-and-hold the left mouse button while dragging the threshold line up or down on thescreen. Release the button at the point where you want the threshold line tostay.

The following are fill graphs without thresholds:

Differential FillThe purpose of the differential fill graph is to vividly

distinguish between the activity of different signals.Especially effective for differential muscle training.

Bottom FillThe bottom fill graph is the sameas above but the color of thesignal with the higher valueextends to the bottom line of thegraph.

Zero Point FillThis type of differential fill can be used in line graphs and in scrolling chartdisplays as shown below. The zero reference point is useful for showingdirection of change, for example in Temperature warming/cooling and SkinConductance response displays.

Rainbow Fill

Especially effective in Temperatureand Skin Conductance displays,Rainbow Fill graphs provideincremental color rewards.

Specialty Fill GraphsThe following are special purpose fill graphs developed for particular modalities.These displays are discussed in the sections below devoted to displays, settingsand parameters specific to each modality.

EMG Displays:FFTand 3D FFT displays are discussed in the EMG Displays section below.

Threshold Bar GraphA standard bar graph with an adjustable threshold line, pictured below center.Threshold adjustment instructions are the same as for line graphs with thresholdson page 21.

Zero Center Bar DisplayPictured to the right below, the center of the scale in this display is zero, withnegative values below and positive values above. The bar fills either up or downdepending upon signal polarity. It is used for displaying signals, such as rate ofchange, that can move in either positive or negative directions.

History Bar Display30-sec averages are displayed in this scrolling bar graph display pictured belowin the History or Trend Displays section.

Numerical Displays

These digital displays enable background monitoring of signals that are not theprimary focus.

History or Trend Displays

History BarsThis scrolling bar graph screen, with its combination of live signals and 30second histograms, is useful for its ability to show trends over time. As each

signal completes one 30 second sweep, a bar is added to the graph showing thethirty-second average value of the signal. We suggest that you leave the signalsweep interval at thirty seconds in order to match the bar graph update. The timeinterval is the same for each bar graph display so that the Faster/Slower Graphbuttons change all graphs simultaneously. You can select and eliminate thesignal sweep line graphs in order to provide more screen space for the historybars. You can change the number of bars displayed using the Faster/SlowerGraph buttons and can even condense the bars to view the entire session on asingle screen. This screen resets when you begin recording a session.

History GraphsStacked Line graphs containing signal combinations moving at a sweep speedtoo slow for feedback, but very useful for seeing a long time interval of thesession and viewing trends over time.

History ChartsAn example of the History Chart Display is pictured in the Scrolling ChartDisplays section in the discussion of display types above. History ChartDisplays are not meant for feedback, however they are much more useful thanfeedback screens for evaluating overall trends. By repeatedly clicking the SlowerGraph button, you can display ever larger time segments, even the entiresession, in a single display window. Autogain is defaulted to ON for this screen.You can manually adjust individual signal magnification by clicking Autogain OFFand using the Gain Up/Down buttons. This screen resets when you beginrecording a session.

EEG Displays

EEG Impedance Screen

This first screen is the hookup and electrode impedance screen. The inputs tothe EEG channels are shown as A+ B+ C+ and D+ for a four-channel application.

A four-channel application will have a Reference 1 and Reference 2 which will beconnected as the monopolar reference. A two-channel application will just have

A+ and B+ and the references will be called A- and B-. In a two-channelapplication you have the option of switching between monopolar and bipolarconfigurations. This impedance test screen is showing the live impedance ofeach electrode to ground. In additional to the digital reading in K-Ohms there arered-yellow-green colored dots indicating: green - under 5K, yellow - between 5and 10K, andred - over 10K. Instructional information, if provided, appears in a panel to the

right with Previous and Next buttons to cycle through multiple pages.

Some applications allow you to assign label names in this impedance screen. Inother applications you will need to click Check & Label in order to assign labelnames. If the application allows, you can label the channels with the site nameas you are hooking up electrodes by clicking the site on the headmap, thenclicking on the white space next to the corresponding channel to the right. After

the impedances are satisfactory, click Check & Label to check raw signals andchange site names if required.

EEG Setup

When you are satisfied with your label names and EEG waveforms, click EEGSetup. This screen is the primary control screen for all EEG feedback. The topdisplay is the raw EEG waveform for one, two or four EEG channels. Below arethe EEG band and threshold control displays which will have between four andtwelve functionally identical displays that can achieve very different effectsdepending upon how you set the adjustable features. Most EEG protocols canbe achieved by adjusting these individual bands and thresholds.

Each EEG channel will have from two to four bands connected to it. The bandsare color-coded to match the trace color of the channel they are connected to.They are further identified by name. For example, Band 2-A indicates that thistrace represents the second band connected to the A channel. This name will beused in feedback displays and in recorded data.

The Band ON/OFF buttonin the upper left corner ofthe band display controlswhether the band is usedas feedback. If this button

is toggled OFF, this bandis not used for feedbackand the top right color bar is grey.

In the three sets of Arrow Up / Arrow Down buttons to the left, the leftmostarrows are used to specify the frequency of the bottom edge of the band (HP),the right-hand arrows are used to specify the frequency of the top edge of theband (LP), and the middle arrows move the entire band up or down by equal

7/25/2019 Isolated i330

increments of .2 Hz. The number in between HP and LP indicates yourcurrent setting for the band width.

The normal convention for setting up the bands is to use Band 1 forReinforcement , Band 2 for Inhibit, and band 3 for artifact inhibit. You should set

up a minimum of two Inhibit bands to eliminate artifact as follows:1. Inhibit settings of 1-4 Hz for eyeblink and lead motion attached to a frontallylocated lead and

2. Inhibit settings of 30-60 Hz for EMG attached to any site.

Threshold Overview

The two horizontal lines in the graph area are the physical positions of thethreshold. The threshold lines do not move. Only the scale of the displaychanges. The controls on the right side of the band are for setting threshold.When the signal line crosses either of the threshold lines the threshold statechanges. The effect of this change is determined by the position of the

Reinforce/Inhibit button.

A green color bar at the top of the controls to the right of the signal bandindicates that your threshold target has been met. Any red bar on the screen willinhibit feedback. When all bands are within target for the length of time (step)that you specify, feedback is given. Feedback will only occur if all bars are greenor grey.

If the signal has been inside the threshold lines for some time and it crossesoutside either threshold line, the indicator will change state and hold state for .1second regardless of what the signal does. This prevents the indicator and

feedback display from flickering. There is no delay when crossing the threshold inthe success direction.
