Page 220: Body Scale (Ble)
Sensors 7.2.1. Body Scale (BLE) Weighing scales (or weigh scales or scales) are devices to measure weight or calculate mass. Spring balances or spring scales measure weight (force) by balancing the force due to gravity against the force on a spring, whereas a balance or pair of scales using a balance beam compares masses by balancing the weight due to the mass of an object against the weight of a known mass or masses.

Page 249: Monitoring Sensors
Sensors 7.3.1. Monitoring sensors These set of sensors are bluetooth pulsioximeter, bluetooth temperature and bluetooth alarm. These three item have the same steps to connect them. Now we are going to describe how to connect each one and how to obtain data from each sensor with a set of simple steps.
Page 250 Sensors If the mobile application has established a previous connection, when the user taps on one monitoring sensors the application will try to connect the last used bluetooht sensor, but if this connection fail the application will show the new scan screen to discover the device again. There is no limit about number of connected bluetooth devices on iPhone but on Android these is a limitation of three bluetooth peripherals connected (plus MySignals device), this was made to provide the application a stable connection along all the lifecycle until the user quits the mobile application.

Page 253 Sensors Each time the user want to disconnect from a monitoring type sensor, just toouch again on the blue lighted sensor and it will turn grey and dissapears from main data screen. These kind of sensors perform a reconnection periodically, then if the user has these sensors selected but the bluetooth device is turned off just wait until the application reconnects with the bluetooth sensor.
Page 254 Sensors When the mobile applications receives a new data entry from a bluetooth sensor the icon will turn green, but if the mobile application does not have new data from the bluetooth sensor the icon will turn orange and the application will show the lasta value obtained.
Page 255 Sensors On these version we introduce a new sensor, the panic alarm button, these button starts s sound and a buzz to warn people about a problem and also sends an alert message. As the detail screen shows, the user can send an email or sms to notify the user about a problem, also it is possible to set a custom message and a phone number as destination.

Sensors 7.3.2. Sampling sensors This set of bluetoth sensors isprovided by bluetooth blood pressure, bluetooth glucometer and bluetooth scale. As said with monitoring sensors, there is no limit about number of connected bluetooth devices on iPhone but on Android these is a limitation of three bluetooth peripherals connected (plus MySignals device), this was made to provide the application a stable connection along all the lifecycle until the user quits the mobile application.
Page 257: Selecting Sensors
Sensors 7.3.3. Selecting sensors It is very easy to select these kind of sensors, just tap over each one and they will be selected and show up on main data screen. To deselect these sensors just tap again and the light icon will turn grey and will disappear form main data screen.
Page 258 Sensors The first time the button connect is pushed, the mobile application will show a new screen to select the bluetooth sensor, this screen will show only bluetooth sensors provided with MySignals. The following tries the application will establish a connection with the bluetooth sensor and in case the mobile application cannot establish it will show a new screen to discover bluetooth sensors.
Page 259 Sensors After that the sensor starts measuring: -259- v2.9...
Page 260 Sensors We introduce another new feature available on bluettoth blood pressure sensor. This screen allows the user to set the measure interval on blood pressure, this values start from 30 seconds to 1800 seconds. Blood pressure sensor will start measuring again after this value and it will loop until the user exits from detail screen or turns off the bluetooth device.
Page 261 Sensors If you choose”Make new measurement” you will start a little wizard that shows how to perform a measure, this wizard required a 2-steo setup: first one, “make sure that the scale is turned off “and second “step on the scale”. Sometimes, when the scale is turned off and the user steps on again, the sensor scale can display a not accurate weight, in this case you should step off the scale until it shows zero weight, then you can step on again to perform the measure.
Page 262 Sensors When the scale connects with MySignals applciations, the blue button labeled as “Measure” turn green. After that wait a moment until the new measure is received from the scale sensor into the application, as a result the application will let you know when the process has finished. -262- v2.9...
