Welcome to FSA Version 4

Welcome to FSA Version 4.0 Components of an FSA The FSA system consists of one or more sensing mats (pressure or temperature) or individual sensors, an interface module, connecting cables (accessories), computer software, and often a manual calibration kit. FSA Sensing mats are comprised of thin, flexible fabric piezo resistive sensors and are typically covered with polyurethane coated rip stop Nylon. The interface module is the electronic interface between the mat sensors and the computer. The interface module connects to the computer via the USB cable supplied with the system. FSA 4 computer software allows the clinician to scan, record, annotate, file and share the information gathered by the sensors. FSA 4.0 software is a 32-bit compilation optimized for Windows XP and up (see System Requirements for current minimum and recommended system requirements). We advise all FSA users to read this entire instruction manual before trying to operate the FSA Pressure Mapping System.

An Overview of FSA 4 for FSA 3.1 Users

FSA 4 is intended to be easier to install, configure and use while offering more features than FSA 3.1. The software has a modular design so that it can be quickly re-shaped into custom applications, but it is still in many ways the same as version 3.1; the user opens a file, scans and annotates new readings and then saves the readings to file. The following summarizes where the new software is different:

More sophisticated FSA files The 3.1 FSA files contained client info and a series of recorded frames. An FSA 4 file contains the client info along with one or more recordings. Each recording can be a different type, so an FSA file could contain information about a client along with a left shoe recording, a right shoe recording, a pair of shoes recording, and an ortho test recording, all in one file. The client info and each recording appear as a tab allowing the user to quickly switch between them. Each recording contains all the information required to display the readings as they were originally recorded. More sophisticated calibration files, the sensor array file The FSA 3.1 calibration files contained information such as the number of rows and columns of sensors, the range to which those sensors were calibrated, and some information gathered during the calibration process. Calibrating to different ranges required creating another cal file. In FSA 4 the "cal file" is replaced with a sensor array file. For every mat there will be one (typical) sensor array file. The sensor array file contains a detailed description of a sensor array (aka mat) including the number of rows and columns, the recommended range, the size and shape of the mat right down to the shape and colour of its cover and cable. Along with the mat description, the sensor array file contains a collection of calibrations, including a "factory" cal that the user cannot delete or overwrite. This one to one relationship between mat and mat information should simplify the user experience. Each sensor array file can simply be named the same as the serial number of the mat, no need to encode the range in the filename. All sensor array files are stored in the FSA SensorArray directory (aka folder).

The end of the INI file Instead of configurations stored in an INI file the new software uses templates to create new documents. Templates are simply FSA documents that contain no readings, and are stored in a separate directory, the FSA Templates directory (aka folder). Adding a new "configuration" is as simple as copying a file to this directory.

Snazzy new look The new software has a new XP style. The toolbar has been cleaned up and is moveable. The display shows a mat with its cover and cable. Readings are drawn on top of the mat making it easy for the user to relate what they see on the screen to the real world. The display is divided into panels with a different control in each panel. Right-click on a panel and select the control you want to see in that panel. Resize each panel by dragging the line that divides the panels. Rightclick on a divider to swap panels to the opposite sides of the divider or change from a horizontal to a vertical line. Rotate the surface plot by clicking on a corner of the mat and dragging it about its center. Don't like the statistics you see? Click on any one of the stats and select a different one from the popup list. Use the arrows on the legend to adjust the colours. Click on the colour bar in the legend to toggle from colour steps to blended colours. Once your satisfied with the layout save it to the template directory so you can create new documents that have this same layout.

Intuitive hardware configuration As much as possible the user has been shielded from the hardware details, however, in the event that they are required to change a setting they can do so in a much more intuitive manner using the System Settings dialog box found under the menu bar selection Tools. Instead of a series of tabbed windows within tabbed windows the user is presented with a tree representation of the hardware for one click access to the settings they need.

User Manual for FSA Pressure Mapping Systems 7th Edition

The Calibration Wizard The Calibration Wizard is accessible directly from the Tools menu. The Calibration Wizard has had a face lift and has reverted back to the easy one-large-inflator calibration process. When the FSA 3.1 cal wizard finishes it creates a new cal file and verification file. The new wizard doesn't, instead it adds a new calibration to the current sensor array file and, if it performed a verification, it attaches the recording to the current document. If the current document contains a single empty recording then that recording is deleted. No need to seek out the verification file and open it, its already open in the current document. The verification can be reviewed and then saved or discarded.

Video without VideoPort To record frames with video simply open System Settings from the Tools menu and check the "Use camera" check box. The 3.1 software required that the user select a special video configuration and all frames in the recording have to contain video. With FSA4 the video feature can be turned on and off at will. There's no need to commit to using video for an entire recording. Record some frames with video and others without. All recordings have the ability to include video. Captured images appear in the bottom right corner of the display. To enlarge the picture click and drag the divider that separates the note and picture from the rest of the display. The note and picture always have the same height while the picture automatically adjusts its width to be four-thirds its height. FSA 3.1 is limited to recording little more than 60 frames with video (no matter how much memory you had) but the new FSA 4 software is limited only by the amount of memory on the computer.

FSA logo The FSA logo is displayed in the software at all times.

Selectable regions The user is now able to select regions of a mat and generate statistics for each region.

Time plot Time plot contains a plot of a selectable statistic over a period of time.

Do-it-yourself tools The software's functionality will be extendable by adding tools. Tools would consist of scripts (Java, Visual Basic etc) or special DLLs that would have access to the current document. These tools could be used to extract information from the document into a user specific format, modify the recordings or record a set of readings in a user defined way. The possibilities are endless. All tools are stored in the Tools directory (aka folder). Adding tools will be as simple as copying a tool file into the Tools directory.

Care and Maintenance of your FSA Hardware

1.3.1

Proper Care of the FSA Interface Modules Do not drop the interface modules. There are no user serviceable parts in the interface modules, do not open them. Protect the interface modules from exposure to moisture. Store the interface modules in a location where it is protected from falling or in the original packaging (inside of the foam core store in the shipping tube). The Type 4 Interface Module operates on 9V DC or battery power. To protect against possible damage to the interface module, use only the Vista Medical supplied power supply provided with the system, refer to safety notices indicated below. Disconnect the battery pack from the module if not in use for an extended period. The Type 5and 5E Interface Modules operate on power supplied by the computer via the ferrited USB cable provided with the system. Use only the Vista Medical supplied USB cable provided with your Type 5 and 5E Interface Modules. Do not remove the ferrites on the USB cable (2) or the sensing mat cable (1) supplied with your Type 5/5E Interface Module and mat. If module function stops during use, reset the module by disconnecting then reconnecting the power source from the device. We recommend the use of a suitable surge protector with the FSA interface module, as would be appropriate with any computer and/or computer peripheral. Type 4 Interface Module only - plug the mat's ribbon cable securely into the interface module, be sure to keep the connector straight when inserting and removing so as not to bend the pins. It is the operator's responsibility to ensure all cables are in good condition; inspect all cables for nicks or abrasions prior to each use. To clean, disconnect the module from the power supply. Wipe the exterior of the interface module with a soft cloth dampened with water. Do not use liquid or aerosol cleaners which may contain flammable substances.

Also see Safety Notices: CAN/CSA C22.2 601.1-M90, UL 60601-1 and EN60601-1, Electronic Emissions Notices Improper care and /or use of the FSA Interface Module could possibly lead to malfunction, failure or damage to the FSA Interface Module.

If function stops during electrostatic discharge to the device, reset the system by unplugging from the PC, rebooting the PC and plugging in the module.

Proper Care of the FSA Mat

Do not fold the mat. Keep the mat dry. Protect the mat from incontinence, torque and shear forces by using the isolation bags provided. Place the mat gently on surfaces by using the corners. Do not pull on or carry the mat by the ribbon cable. Do not pivot on the mat. Do not pull on the edges of the mat while it is under a client. Do not pinch the mat between moving components of a support surface. Store the mat flat or in the original packaging (roll the mat around the foam core and store in the shipping tube). The Nylon covering should not be put in direct contact with broken skin. Improper care of and /or use of FSA mat(s) could possibly lead to malfunction, failure or damage to the FSA pressure-sensing mat.

1.3.3

Cleaning the FSA Mat

FSA mats are typically covered in Polyurethane coated ripstop Nylon or 10 mil Polyurethane. We recommend you use the isolation bags provided with your system at all times to protect against incontinence as well as torque and shear forces. If a small stain does occur, we suggest cleaning with a gentle shampoo in the following manner: Dip a DAMP, not WET sponge or cloth into a small (quarter sized or smaller depending on size of stain) amount of the shampoo. Gently apply to the covering using a light swirling and patting motion. Apply only the pressure of the sponge or cloth, do not rub the mat. This should remove most stains. Blot to dry. Allow FSA mat to dry thoroughly before use. Mild alcohol based cleaners in non-wetting amounts may also be used. Isolation bags are intended for single use only; dispose of them according to your institution's biological waste disposal guidelines.

Component Description

2.1.1

Contents of the Shipping Tube Type 4 System Shipping Tube with White Shipping Foam your typical FSA system will arrive with the sensing mat wrapped around the foam core, and the interface module and other accessories inside the foam. Save the tube and foam for storage or transportation of your FSA system. Typical FSA Mats are covered in a polyurethane coated ripstop nylon fabric. The mats have an attached ribbon cable covered with a black nylon braided cable sleeve and a 34-pin plug; the cable also gives the serial number and orientation (top/bottom) of the mat. The Nylon covering the FSA mat is blue on one side and black on the other. For easy orientation, blue is on top. For purposes of good hygiene, to protect against tension and incontinence, and to increase durability of the mat ALWAYS use the FSA Sensor mat with an isolation bag.

Templates

Templates are similar to what used to be called a configuration or scheme in older versions of FSA - like configurations, your mat requires a template to allow the FSA operator to display the data collected from the FSA hardware. The template collects hardware information from FSA 4 sensor array files (*.cal) such as the array size and calibration units and creates a suitable template. You can create and save your desired display settings as a new template. You may want to do this if you have set up a particular set of display options that suit your application and you would like to use that setting consistently. While you can certainly select the default template and make display adjustments every time you use the software, it would save time and provide consistency to save your preferred display options so you can repeat them each time you pressure map.

Clicking on Interface Module will allow the operator to: change the Port the Interface Module is connected to the computer through. select or deselect High Speed mode Upload Firmware when required (see 'Upload Firmware').

Clicking on the mat icon will allow the operator to: select the sensor array to use. select or deselect the option to Always use newest calibration. select the calibration range to use for multiple calibration range mats (deselect 'Always use the newest calibration' to enable the option). delete the selected calibration. You cannot delete the factory sensor array file's calibration. The Time and Range details for the currently selected file will appear below the calibration range drop down. 3.3.5.5

Scan Rate

The FSA computer interface module can read up to approximately 10 000 sensors per second when set to High Speed (see Tools-System Settings). Half of that when High Speed is not selected. A typical 16x16, 256 sensor mat can read up to approximately 40 Hz with High Speed selected. 10 000/256 sensors = 39 Hz. To convert Hz (reads per second) into seconds per read, invert the number ; e.g. 0.5Hz = 0.5 reads per second 1/0.5 = 2 seconds per reading e.g. 0.1Hz = 0.1 reads per second 1/0.1 = 10 seconds per reading To convert Hz (readings per second) into readings per minute, multiply by 60; eg. 0.5 Hz = 0.5 x 60 = 30 readings per minute. eg. 0.01 Hz = 0.01 x 60 = 0.6 readings per minute. 10 readings per second = 10Hz

1 reading per second = 1Hz 1 reading every 10 seconds = 0.1Hz 1 reading every 20 minutes = 0.05Hz 1 reading every 30 seconds = 0.0333Hz 1 reading minute = 0.0167Hz 1 reading every 10 Minutes = 0.0017Hz 1 reading every 30 minutes = 0.0006Hz 1 reading per hour = 0.0003Hz High Speed mode should be deselected when using a dual mat set up. Actual speed varies due to ceilings imposed by the computer itself, and varies slightly computer to computer . Actual speeds will vary mat style to mat style, computers typically cannot process fast enough to accommodate mats with a low number of sensors to 10 000 sensors per second. 3.3.5.6

Upload Firmware

You may need to Upload Firmware to your interface module after a software upgrade, or if your Interface Module's programming becomes scrambled. If you see a solid yellow light on your module which neither restarting your computer or power cycling your Interface Module clears, you should do an Upload Firmware. This action will upload data to your FSA Interface Module from the FSA software. Make sure your Interface Module is connected to your computer and powered up. 1. Start your FSA software and allow the software to autodetect the module. Try test scanning to make sure the computer is communicating with the Interface Module, if you can, or go to Windows Start-Control Panel-System -Hardware-Device Manager to determine what COM port Windows has assigned your module. Look for "USB Serial Port" under Ports (COM & LPT). 2. Go to Tools-System Settings, click on the Interface Module icon in the device tree on the left. 3. Note the COM port your Interface Module is on from the Port dropdown on the right, if not determined earlier, or select the Port number found under Device Manager earlier. 4. Click the Upload Firmware button. The Upload Firmware Wizard will start. 5. Follow the Wizard, selecting the options that applies to your situation, clicking Next when prompted. 6 Power cycle your module after the process has completed by dis and reconnecting power to the module. After the power cycle, the green LED should be illuminated. NOTE: If using a USB capable Interface Module (any of the Modules with a serial number containing a 'U' or 'T'), do not perform an Upload Firmware unless running FSA 4.0 release 199 or up. If this has already occurred and you cannot clear the yellow light, upgrade your FSA 4.0 software from www.pressuremapping.com and repeat, including dis and reconnecting the power to re-set the device. If you cannot clear the yellow light, please contact technical support at [email protected] You may have to send your Interface Module in for reprogramming.

Key Frames

The ability to mark frames as Key Frames is new to FSA 4. A Key Frame is not the same as a Selected Frame, the latter option is intended to be used in editing and printing operations. The Key Frame option was developed to allow the FSA operator to mark specific frames in a file containing a high number of frames, typically a file that was collected using the Record and not the Scan function, and quickly view just those frames instead of going through a large file frame by frame searching for key information. You can mark a frame as a Key Frame manually by clicking the star outline in your Status Bar in whatever frame or frames you like. The star will appear illuminated if selected. To view only your key frames: Hold down the CTRL key and scroll through your FSA file using the wheel on your mouse (if you have a wheel mouse), the UP and DOWN arrows on the scroll bar on the right side of your colour bar or by hitting the or keys on your keyboard. Only the frames selected as key will show. If you release the CTRL key, all frames will show. Use the Skip Forward or Skip Backward functions in the Navigation Tool bar. An illuminated star will show in the FSA Status Bar if a frame is selected as a Key Frame.

As of the writing of this manual, FSA automatically marks as 'Key': - the final frame recorded when the Record function is disengaged. - any frames collected using the Scan function. - the final frame collected prior to disengaging the 'remote trigger while using FSA in Remote mode; this marks the end of each set of collected frames in Remote. This default setting will be made optional in a future release of the software., please keep an eye on Tools-Options, General in future software releases or contact [email protected] for further information.

The Contour Plot

Example of the Contour Plot, Seat template selected, with no data collected.

Example of the Contour Plot, a frame from a seating evaluation file.

The Contour Plot is a 2D, colour display of your sensing array data. It also shows your numerical pressure values if that option is selected. By default, the data collected during your pressure mapping session will include the entire array, which includes 0 values as indicated in the example above. Likewise, the Sensing Area (cm ²) statistic will include the entire array. You may want to change the bottom of the scale to .1 instead of the default 0 to remove the values up to .1 from displaying in your graph and being included in your data (in above example the default of 0 is selected, see all the 0's). Also see The Legend Display Panel.

Above are examples of the same frame with the display options changed. Image 1 'Show Contours' and image 2 'Show Color Blocks' via the Contour plot's context menu, and option 3 'Blend Colours via the Legend Display panel.. The actual numerical data is not affected. Note that 'Blend Colours' only affects the 'Contour Plot' when the 'Show Colour Blocks' display option is selected. Gradient The option to display Gradients instead of Normal values is available from the Contour Plot context menu. Gradient is an expression of the change in readings from one sensor to the next; it shows how close the high pressures are to the low pressures. Fluids tend to flow from high pressure areas to low pressure areas, especially if they are close. In the FSA software, the gradient is always expressed as units/cm (eg mmHg/cm, psi/cm...). Turning on this option affects the Contour and Surface plots as well as the Minimum, Maximum, Average, Variance and Standard Deviation statistics values and units. The units range defaults to 50% of the pressure range; in order to increase the size of the gradient arrows that appear in the Contour Plot display, decrease the top of your range to suit by clicking on the down arrow at the top of the Legend (color bar). You may want to set your font size to medium or large. If your units run off the right side of the display, right click over your main display area select 'Show Splitters', then drag the splitter on the left of your Legend display panel left to suit.
