A USB connection can also be used to download the recorded data to a PC and for updating the firmware. All recorded vital sign and processed data can be downloaded. It is a convenient, economical way for later review of the recorded histories. 1.3 Features The main features of MOBISERV data logger are: 1. monitoring ECG, Respiration and 3-axis acceleration, 2. extraction of the Heart Rate (HR), the Breathing rate (BR) and the activity classification (lying, standing, walking and running), 3. recording and / or streaming the raw data and the extracted parameters, 4. allowing user to store up to 2GB of data, 5. removable SD memory card, 6. one battery Li-Po for more than 8 hours continuous operation (recording mode), 7. USB 2 FS interface for battery charge, download data and firmware update, 8. Bluetooth 2.0, 9. LED showing the battery status, operating mode, Bluetooth state, … 10. Jack connector for electrical connection to dedicated garment with smart textile, 11. Mode switch for the selection of the operating mode. 12. ANTTM AP2 for wireless body array network MOBISERV FP7 248434 D5.3: Multi-sensor system integrated into wearable fabrics 9/45 2 Garments Within the scope of MOBISERV two different types of garments have been designed and produced for vital signs monitoring: the first one refers to sensorised shirt and band for day use, and the second one to pyjama for night use. After the first prototype of garment (see deliverable D5.2) and following the remarks of the users, a second generation of garment have been designed taking into account the use of new technology for the respiration measurement (IPG at the place of strain gauge sensor). In this document the second prototypes of garments are presented. 2.1 Sensorised shirt and Band The first trials carried out with the end-users highlighted that the older persons encountered some difficulties to wear the first version of shirts. Although older people generally like loose clothes, they were happy to have them fitted at chest level and moreover they like the vests with straps as they can easily slip into them without lifting their arms above their head. To respond to this feedback a second version of shirts for the day monitoring has been designed to grant easiness of use as a primary goal thanks to a zip fastening that can be totally opened to facilitate the donning. Two more electrodes have been added to the shirts and band in order to be able to monitor the respiration through thoracic impedance measurements thus removing the piezo sensor with the aim to increase comfort and reduce the overall production costs and time. However, in the band, the piezo sensor for respiratory movement detection has been maintained in order to be able to perform comparative tests if needed. The shirts are made with cotton fabrics which is one of the preferred materials by older persons. Both shirts and band presents: four textile electrodes placed on the chest region to detect ECG (1 Lead) and respiration through bio impedance measurements one mini jack connector to plug the electronic a pocket to house the electronic during use a Velcro® fastening for the band and a zip for the shirts Shirts and band are illustrated in Figure 1. Figure 1 The female shirt (left), the male shirt (centre) and the band (right) MOBISERV FP7 248434 D5.3: Multi-sensor system integrated into wearable fabrics 10/45 Figure 2 The 4 textile electrodes in the inner side of the male shirt Figure 3 The piezo sensor (up) and the 4 electrodes (down) in the band 2.2 Pyjama For the night monitoring a new version of the Pyjama has been designed. The second prototype of pyjama includes two temperature sensor to address the need to monitor the skin temperature during the night in order to prevent discomfort problems related to uncompensated nocturnal heat loss which are quite commons in elderly. The chosen sensor is a commercial thermistor which gives reliable information with a 0.1 degree of accuracy. Two sensors has been integrated, one in the cuff and one in the hip region respectively. The choice of the location is the result of two different goals: the aim to maintain comfort for the user on one side, and the need to grant a good contact with the skin in order to reach a thermal equilibrium with the body on the other side. The chosen regions seem to be the best trade off between reliable information and comfort for the user. MOBISERV FP7 248434 D5.3: Multi-sensor system integrated into wearable fabrics 11/45 Figure 4 Temperature sensors inserted in the hip (left) and in the cuff (right) A specific ANTTM module has been designed to interface properly the sensors as explained in chapter 3. Pyjama presents: four textile electrodes placed on the ankles and cuffs that can be used to detect ECG signals (up to 3 Einthoven leads) each of them with adjustable fastening. one mini jack connector to plug the main electronic one ERNI connector to plug the ANTTM temperature module a pocket to house both the electronic during the sleep Figure 5 The male version (on the left) and female version (on the right) of the pyjama MOBISERV FP7 248434 D5.3: Multi-sensor system integrated into wearable fabrics 12/45 3 ANT for Wireless Body Array Network TM The new multi-sensor system integrates a Wireless Body Array Network (WBAN). This WBAN enables to add sensors which can be distributed on the body. The technology used is ANTTM ecosystem. However, the use of the WBAN has some restrictions concerning the wave propagation around the body. A wireless temperature sensor has been specifically designed and integrated in the pyjama to monitor the skin temperature of the subject in two different sites. 3.1 Hardware description MOBISERV ANTTM module provides the following accessories: one 3-pin ERNI connector for the thermistors one on/off switch one status led blinking when transmitting TM Figure 6 MOBISERV ANT module with the housing 3.2 Specifications 3.2.1 System Specifications TM An overview of the general characteristics of MOBISERV ANT AT3 module are listed in Table 1 Table 1 System specifications Characteristics Power management Battery CR 2430, 3V Lithium coin cell (disposable) Battery capacity 280 mAh Autonomy Autonomy while streaming Up to 560 hours Temperature Operating 0 to 50 °C Storage -20 to 50 °C MOBISERV FP7 248434 D5.3: Multi-sensor system integrated into wearable fabrics 13/45 Characteristics Humidity Operational up to 95% non-condensing Communication interface Wireless ANTTM wireless module ANT11TS33M5IB Certifications FCC Test ready (CFR47), RHOS compliant Device Dimensions 41 x 41 x 23 mm Weight 27 gr. 3.2.2 Measurement Channels Specifications The developed module has been designed with two identical analog front-ends to measure the resistance of the sensors.

In the first version, the respiration sensor was a strain gauge, in this second version, there is the possibility to use either a strain gauge or the impedance plethysmography measurement. CSEM has redesigned the user interface by adding 4 LED. The jack connector is now integrated into the housing in order to increase the ergonomic. The embedded signal processing has been improved. In this second version, the fall detector is not yet implemented. The next version of software will offer this feature. This second version of MOBISERV data logger provides the following features: one 4-pin jack connector for textile sensors (ECG and IPG or strain gauge), one USB connector for configuration and data transfer, one micro-SD memory card slot, four status light, one mode switch, one reset switch accessible through a hole. Figure 7: Data logger overview 4.2 Micro-SD card memory The device records data into a micro-SD card memory. The device will immediately stop recording if the memory is removed while in operation. Please note that only the provided 2GB micro-SD Card (reference: Sandisk SDSDQ-002GE11M or Kingston SDC/2GB) have been fully tested. No support for other brands or memory models can be guaranteed, neither support for SDHC cards or non-compliant cards. MOBISERV FP7 248434 D5.3: Multi-sensor system integrated into wearable fabrics 17/45 This device has only a very limited support for a file-system. An SD card used with the MOBISERV Data logger can only be filled with data from the MOBISERV Data logger. Once formatted by the device, it should not be used to store other files on it.

This is the fist step before integrating the WHSU with the rest of the MOBISERV components to support F08: Encouragement for exercising. The idea has been to offer a Graphical User Interface to enable the control of the data logger as well as the visualization of the data extracted from an activity session and the information that can be drawn. Java Runtime Edition JRE 1.6.0 update 27 and newer is used for programming language. Figure 8: Collaborating components of WHSU 5.2 Blocks specification The following paragraphs describe summarily the operation of each object used in Figure 8 and the interaction between each block. 5.3 Device Device is the data logger embedded in the garment. This device has the ability to perform the operations listed hereunder. MOBISERV FP7 248434 D5.3: Multi-sensor system integrated into wearable fabrics Bluetooth operations Connect. Disconnect. Start the streaming of the signals. Stop the streaming of the signals. Start the recording of a session. Stop the recording of a session. Get the data blocks of the streamed signals. USB operations Connect. Disconnect. Download the session. 5.4 25/45 DeviceManager The device manager is a service that handles the operations coming from the upper layer (GUI manager). According to the command coming from the application it initiates an operation on the device, e.g. when it receives a start streaming command, it connects to the device and start the streaming and signals buffering. 5.5 DownloadManager DownloadManager is a daemon application, which automatically handle the USB connection and downloads existing sessions in the Data Logger SD memory card. 5.6 SessionManager This is the object in charge of storing the information of the sessions in the data recording folder in order that user will be informed about the sessions downloaded. 5.7 GUIManager GUIManager is the complete application enabling the user to see and analyze the data acquired during one session. 5.8 DataBase DataRecording contains the information of the sessions saved in the hard disk of the PC used for analyzing purpose. 5.9 Integration into Kompai Root DataRecording is just a folder containing the session files in EDF format. This is applicable only when WHSU is used in stand-alone mode. For the integration in the Kompai Robot, a data base (DataBase) will be created. GUIManager will be replaced by ExerciceManager. This object will be outside the stack. It will work as a wrapping class written in C# to enable the translation of the operations coming from the upper layer to the stack which is written in Java.

The second part concerns the use of the Graphical User Interface, that means: real time monitoring (streaming mode), daily monitoring (recording mode). Both modes can be used simultaneously. The software package used for the Mobiserv project is split into two main parts: a daemon running in background which is in charge of downloading new sessions to the PC, a viewer which is providing the user the ability to make operations such as streaming, recording and viewing online signals (streams) and offline signals (sessions). The diagram below describes the main architecture of the two parts of the software package and how they interact with the hardware. Figure 10:Interaction between the PC software parts and the SEW3 6.2 Conventions 6.2.1 Operating system Microsoft Windows7 is the operating system chosen as reference system for the development of the application. The software is written in Java only to make profit of portability. The software has been tested on Microsoft Windows7 and Mac OS X and therefore is available for both OS. 6.2.2 Requirements The requirements listed on the following paragraphs have to be fulfilled. MOBISERV FP7 248434 D5.3: Multi-sensor system integrated into wearable fabrics 28/45 6.2.2.1 Hardware requirements The Data Logger is required only for streaming mode.

PC or MAC with Bluetooth device enabled. 6.2.2.2 Software requirements The OS available are, as aforementioned, the following: Windows7 or Mac OS X, Java Runtime Edition JRE 1.6.0 update 27 and newer. Java should be contained in the path in order to run this software by one click. This is provided by default in nowadays computers, Mobiserv software stack which is contained in single zip file named: mobiserv-platform-xx-yyyymmdd.zip. 6.2.3 Root The main root folder has to be fixed once and for all. This root folder will be used for the application resources, such as the stored location of the GUI configurations. 6.3 For both OS, the root is: C:\Users\Mobiserv Preparation Decompress the zip file mobiserv-platform-xx-yyyymmdd.zip provided with a tutorial (xx: version/revision, yyyy: year, mm: month, dd: day) Copy the folder mobiserv in the root folder specified in the paragraph 6.2.3, according to the available operating system Figure 11 shows the arborescence of the new mobiserv folder. Folder and subfolder have to be keep as there are Figure 11: Mobiserv folder and subfolders tree The content of the subfolders is the following: Subfolder downloader: contains files used for the downloader application. MobiservDownloader.jar is the application file. Subfolder projects: contains the project file Mobiserv.mdq to be used to generate the customized views for the Mobiserv project Subfolder sessions: contains the downloaded sessions Subfolder log: contains the log files for development purposes MOBISERV FP7 248434 D5.3: Multi-sensor system integrated into wearable fabrics 6.4 29/45 Downloader USB driver uses with the data logger has to be installed before doing anything else. The downloader tool can be downloaded from the following link: http://csnej106.csem.ch/sec251/sewOS/#host_software Currently, only the Windows7 version is available. The downloader application runs in background and downloads new sessions without any action from the user. Double clicking on MobiservDownloader.jar will start it. Figure 12: Starting Mobiserv Downloader It is strongly recommended to make a shortcut to this jar file in a more convenient location to launch it. The launch of the MobiservDownloader application provides this message. Figure 13: Message telling a successful start of the downloader Once the data logger is connected via USB, all new sessions in the SD memory card are downloaded in the sessions folder without any notification. The idea is to keep this program running in the silent mode. 6.5 Viewer The new viewer, developed for Mobiserv is a graphical user interface that plots the sessions and the streamed data on a PC display.
