3. Preparation for use

3.1 Pairing Gamma Sapiens with the iOS device

1) Go to Settings on your iOS device, look for the Bluetooth and make sure the Bluetooth is on.

2) Activate Gamma Sapiens by pressing and holding the on_off_2 button (during 4 seconds) until the green LED indicator is continuously lit. After that release of the on_off_2 button makes Gamma Sapiens discoverable and ready to be paired.

3) In the Bluetooth menu of the iOS device, wait until the iOS device discovers Gamma Sapiens and displays its name in the format:

 

GS#XXXXXX,

 

where XXXXXX is the serial number of Gamma Sapiens. Then select a necessary Gamma Sapiens you want to make Bluetooth pairing with. After successful pairing with the iOS device, Gamma Sapiens will automatically switch off. If pairing is not achieved during three minutes, Gamma Sapiens will be also disabled.

 

4. Use of GS Ecotest

4.1 Getting started

The “GS Ecotest” application is ready for a connection immediately after it is opened. If Gamma Sapiens is already paired with the iOS device, a single short press of theon_off_2button will be enough to turn Gamma Sapiens on.

 

After that Gamma Sapiens will make continuous measurement of DER and DE, trying to connect to the iOS device with which it was previously paired. If the connection is successful, the green LED indicator will start blinking slowly. If the connection is not established for two minutes, Gamma Sapiens will automatically turn off.

 

4.2 General principles of “GS Ecotest” performance

4.2.1 Main operating modes

The user interacts with key features of the “GS Ecotest” application using the following modes:

·        Indication mode;

·        Map display mode;

·        Database view mode.

The user can switch between separate modes by using appropriate buttons at the bottom of the screen under the window heading. Each operating mode offers the user a certain set of functional capabilities that, along with graphical tools for information representation, are described below.

 

Some application’s events such as threshold level exceeding, disconnections, etc., are registered in Notifications.

 

4.2.2 Features of dosimetric information measurement and display

4.2.2.1 DER measurement looks the following way. After beginning a measurement process, measurement results and associated statistical errors will appear on the iOS device’s screen in the Indication mode window of the GS Ecotest” application. During measurement the statistical error of each subsequent measurement result decreases and reaches over time a specified statistical error. As soon as this error is met, the measurement process is still in progress, but part of statistical data is no longer considered. That is why all subsequent measurement results will be displayed with the statistical error that is lower than or equal to the specified one.

 

The “Gamma Sapiens” device automatically determines the specified statistical error depending on the radiation intensity. The appearance of the gray statistical error indicates that its value is greater than that of main relative permissible error limit in DER measurement. The value of a statistical error is displayed in a white color when it becomes lower than or equal to that of main relative permissible error limit in DER measurement (see 1.2.2, Operating manual  of the UDKG-01i “Gamma Sapiens” INTELLECTUAL GAMMA RADIATION DETECTOR).

 

4.2.2.2 Measurement of DE as well as dose accumulation time looks the following way. Each time the “Gamma Sapiens” device is on, it starts the measurement of dose and dose accumulation time from zero values and transfers these data to the “GS Ecotest” application for processing and display in the Indication mode window.

 

4.2.3 Features of introduced concepts and terms

For structuring dosimetric information in a database of the “GS Ecotest” application, the following specific terms were defined:

·       Pointlocation that the user determines anywhere, indoors or outdoors. It precisely corresponds to the coordinates of a point at which measurement of dose rate is performed. Dosimetric measurements at one and the same Point mean that measurements are made in exactly the same place indoors or outdoors. A unique name with an automatically created identifier is necessarily typical of each Point in the “GS Ecotestdatabase and cannot be identical for different Points. Points in open spaces may additionally include GPS coordinates;

·       Sessiontime intervals for which a dosimetric device continuously accumulates and transfers accumulated dose to the GS Ecotest” application. Each Session starts with zero values of accumulated dose as well as dose accumulation time, and ends with a value of accumulated dose when this Session is finished. A new Session starts automatically as soon as the dosimetric device is connected to the iOS device and completes when this dosimetric device is disconnected from the iOS device via the Bluetooth interface.

 

With the Reset dosefunction, the user can finish the current Session of dose accumulation on the dosimetric device and start a new Session.

 

4.3 Indication mode

Indication mode displays real-time dosimetric information, and allows the user to choose commands from the additional functions menu.

 

4.3.1 Graphical components of the Indication mode

4.3.2 Description of additional functions menu

The additional functions menu provides the following functions:

·        Disconnect the device via Bluetooth: Disconnects the dosimetric device from the iOS device;

·        Save γ: Stores the current measured value of dose rate in a database.

·        Save accumulated dose: Stores the current value of accumulated dose in a database.

·        Restart measurement: Restarts a measurement process on the dosimetric device.

·        Reset dose: Resets the current value of accumulated dose on the dosimetric device.

 

To make use of these functions, the user should click the onscreen button of additional functions menu, and tap an appropriate item.

 

Help_Screen_2_eng

 

Disconnect a dosimetric device from the iOS device via the Bluetooth interface

To stop data communication between devices and disable the connected dosimetric device, choose the “Disconnect the device via Bluetooth command.

 

Save the current value of dose rate to a database

This function is used to store the current value of dosimetric measurement in the database along with additional information for the user:

·        value of dose rate;

·        dose rate threshold exceeding (if no thresholds are exceeded, “0.00” will be displayed);

·        measurement date and time;

·        measurement statistical error;

·        text comment to a certain measurement;

·        text comment to a certain measurement point;

·        photo comment to a measurement point;

·        sound comment to a measurement point;

·        measurement point identifier;

·        GPS coordinates tagged to a measurement point.

When theSave γ” command is selected, the window for saving dose rate appears, displaying a list of all current dosimetric measurements that will be saved to the database. There are two possible ways to save dose rate: either by creating a new measurement point with a record of the current measurement or by adding a current measurement to the existing (previously created) point.

 

When a new point is created (the “Add to the existing point” function), another window opens. The user will be prompted to enter a unique identifier (name) of the point to be created. If necessary, the user may type a comment to this measurement point.

 

When the current measurement is added to the existing point (the “Add to the existing point” function), the user should select a necessary point from the list of existing ones. In a new window, which is similar to that for creating a new point, the name and comment fields of this point are already filled in. Clicking the Save button saves the current measurement. If necessary, the user may also leave a comment.

 

Save the current value of accumulated dose to a database

This function is used to store the current value of accumulated dose in the database, along with additional information for the user:

·        value of dose rate;

·        dose threshold exceeding (if no thresholds are exceeded, “0.000” will be displayed);

·        dose accumulation time;

·        date and time when accumulated dose was saved;

·        type of a device used for the dose measurement;

·        serial number of a device used for the dose measurement;

·        text comment added to each value of accumulated dose saved to the database;

·        sound comment.

 

To save the current value of accumulated dose to the database, select the “Save accumulated dose” command. Accumulated dose is saved to the database and is related to the current session of dose accumulation.

 

Restart measurement on a dosimetric device

The “Restart measurement” command lets the user restart the measurement of dose rate. The measurement is started with a zero value, while the value of a statistical error equals to 255 %.

 

Reset the current value of accumulated dose on a dosimetric device

This function is intended to reset accumulated dose as well as dose accumulation time on a dosimetric device. After selecting the Reset dose command, the window for saving the current session appears in which the user can enter (optionally) an identifier (name) of the current session before it completes. If the session identifier is not specified, an identifier with the following format Session yyyy/mm/dd, where yyyy/mm/dd is the end time of a session, will be automatically assigned to the current session. You can save the current session to the database and create a new session with the click of the Save button. The saved session automatically records the last value of accumulated dose. The accumulated dose and dose accumulation time will be set to zero values.

 

4.4. Map display mode

 

Help_Screen_4_engHelp_Screen_3_eng

 

To enter this mode the iOS device requires:

·        Internet channel for using maps online;

·        Switched on GPS receiver.

This mode gives a view of main real-time dosimetric data on a map along with a measurement point, which is indicated by the info banner displaying the following:

·        numeric value of dose rate;

·        threshold value and threshold exceeding (displayed in a red color);

·        numeric value of a measurement statistical error and its reliability.

 

The user can tap the info banner to hide or show it. The buttons at the top of the screen let the user choose standard, satellite or hybrid view. The application can also show stored in the database points on a map by dropping one of four markers depending on the dose rate range at this point: діапазон 1 діапазон 2  діапазон 3 діапазон 4.

To show a point on a map, select a corresponding command in the view window for a measurement point or within a view window for a list of measurements or points.

 

4.5 Database view mode

This mode displays dosimetric data that the user has previously saved to the database. The database view window shows two groups of functions under the DOSES and MEASUREMENTS headings respectively.

 

Help_Screen_5_eng

 

4.5.1 DOSES

Functions of the DOSES group make it convenient to process and easy to read the necessary data on accumulated dose in the database for a certain period of time.

 

4.5.1.1 Accumulated dose

The Accumulated dose function allows the user to see a dose accumulation history within a certain period of time as well as calculate the absolute value of accumulated dose for this specific time period.

 

After selecting the Accumulated dose function, a new window appears in which a list of accumulated dose records that the user has previously saved are displayed. Each record in this list consists of a numeric value of accumulated dose, dose threshold exceeding (if no thresholds are exceeded, “0.000” will be displayed), a date and time when the accumulated dose was saved, and an identifier of a session during which a dose was saved.

 

In this window the user can automatically calculate accumulated dose for a specific period of time by choosing the Accumulated dose (1) command at the bottom of the screen. In the dialog box that opens, the user should enter a start and end date and time of a necessary time period for dose accumulation, and then click the Done button. In a new window that opens the user can find the following information: a calculated value of accumulated dose for a specified period of time, start and end dates and times of this specific time period, along with saved records within a particular dose accumulation history, based on which ones the value of accumulated dose was calculated.

 

Help_Screen_6_eng

 

 

In this window the user can find all records of the dose accumulation history of a single Session by using the “Search by session” () command and by typing a necessary session number as requested. When the search is complete, a new window opens, displaying a list of accumulated dose records saved during this session.

 

The user should tap a record in the list to open another window with the detailed information about this record, such as a numeric value of accumulated dose, dose threshold exceeding (if no thresholds are exceeded, “0.000” will be displayed), a dose accumulation time, a date and time when the accumulated dose was saved, a type and serial number of the dosimetric device used for a dose measurement, a comment that the user left when this dose was saved.

 

From this window the user can share data of accumulated dose as an XML file. Tapping 2 at the bottom of the screen automatically starts sharing. This created file is available in iTunes via the File Sharing section. (For more information about backups, see Backing up).

 

Another function is provided for showing a graph (3) based on the values of accumulated dose. If a date search has been done, the graph will display only data within a specific range of dates. The value of accumulated dose on a graph is represented by a dot. The zoom function makes choosing the dot and viewing the graph more convenient. After touching the dot, the view window appears, displaying the detailed information about the corresponding accumulated dose. The graph itself is shown as a plain line. Each subsequent session starts with the values of the previous one. That is, the last dot will be positioned at the value of total dose accumulated within a given period of time.

 

Help_Screen_7_eng

 

4.5.1.2 Sessions

The Sessions function enables the user to view a dose accumulation history within a certain period of time by Sessions as well as calculate the absolute value of accumulated dose for this specific time period.

If the Sessions function is selected, a list opens with Sessions of dose saving. Each record in this list provides information about a single dose accumulation session, including a session name, a value of dose accumulated during this session, a session identifier, a start and end date and time of this session, and accumulation time for which a dose was accumulated during this session.

 

In this window the user can automatically get accumulated dose for a certain time period by using the “Accumulated dose” (1) command at the bottom of the screen. In the dialog box that opens, the user should enter a start and end date and time of a necessary time period for dose accumulation as requested, and then click the Done button. When a new window is opened, the user will see the following: a calculated value of accumulated dose for a specified period of time, a start and end date and time of this specific time period, along with a list of Sessions of dose accumulation history, based on which ones the value of accumulated dose was determined.

 

Help_Screen_8_eng

 

In this window the user can also find all records of a dose accumulation history for a single Session by using the “Search by session” command and by entering either a necessary session number or a name as requested. When the search is complete, a new window opens, displaying a list of saved Sessions of dose accumulation.

 

The user can tap a certain Session in the list to get detailed information about it, such as a value of dose accumulated during this session, a dose accumulation time, a start and end date and time of this session, a session name, a comment that the user added to this session, as well as view all records within a dose accumulation history that the user has previously saved during this Session.

 

Similarly to viewing the accumulated dose, the user can use a graph view function (3) for sessions the user has specified. Tap 3 to open a new window with a graph.

 

4.5.2 MEASUREMENTS

Functions of the MEASUREMENTS group provide an easy way for the user to process and view necessary data on values of dose rate within a specific period of time from the database.

 

4.5.2.1 Gamma

The Gamma function lets the user view a history of measuring and saving dose rate at different points of measurement for a certain period of time, along with this kind of history of a single measurement point.

 

After the Gamma function is selected, a new window appears in which the records list of a history of measuring and saving dose rate is displayed. Each record in this list includes the following information: a numeric value of dose rate, a measurement point identifier (name), a value of a statistical error in this measurement, dose rate threshold exceeding (if no dose rate thresholds are exceeded, 0.00” will be displayed), a date and time when the dose rate was saved.

 

In this window the user can choose all records of a dose rate measurement history of a specified point of measurement by using the “Search by point” command and by typing an identifier (name) of a necessary point as requested. When the search is complete, a new window opens, displaying a history of measuring and saving dose rate at a specified point.

 

To view a history of measuring and saving dose rate at different points of measurement within a specific period of time, the user should choose the “View by date” (1) command at the bottom of the screen, enter a start and end date and time of a necessary time period to measure and save dose rate as requested, and then click the Done button. In a new window that appears the user will see the records list that is sorted by date and composed of a history of measuring and saving dose rate values for a specified period of time at different measurement points.

 

Help_Screen_9_eng

 

The application features also the “Show on a map” (4) function. After tapping 4, the map appears showing all points (only points that fit the search criteria if the search completed) that are indicated by related markers, depending on the dose rate value of this point. You can click the marker to see information about it.

 

Measurements can be shared as XML files (2) similarly to accumulated dose. This created file is available in iTunes via the File Sharing section. (For more information about backups, see Backing up).

 

The user can tap a particular record in the list to open a new window with the detailed information about this record, such as an identifier (name) of a certain point, a text comment that the user added when a measurement point was created, GPS coordinates of this point (coordinates are displayed if they were detected when this point was created. Otherwise, 0.0000, 0.0000” will be shown), along with the following information: a value of dose rate and dose rate threshold exceeding (if no dose rate thresholds are exceeded, “0.00” will be displayed), a date and time when this dose rate was saved, a value of a statistical error in this measurement, a type and serial number of the dosimetric device used for a dose rate measurement, and a comment that the user left when a dose rate was saved.

4.5.2.2 Points

 

The Points function allows the user to view a history of dose rate measurements at each necessary point of measurement.

 

Each Point in the list is assigned a unique name and a six-digit identifier. The search for a necessary Point can be done by both its name and identifier.

 

After selecting the Point, a new window appears, displaying information about it.

 

The view window shows detailed information about this Point as well as all saved measurements made at this Point. To see an expanded description (time, statistical error, device type, etc.) of the measurement cell, tap this cell.

 

Help_Screen_10_eng

 

In edit mode the user can change a point name, a text comment, a photo comment, a sound comment as well as a text comment added to each single measurement.

The photo comment includes a photo with the application icon and the dose rate value of the last measurement. This image can be also posted to one of the social network. See Social Networking Integration.

The sound comment is a file that is recorded on a speaker and is attached to a certain point. After the “Sound comment” command is selected, a new window appears in which you can listen to the recording. If the point is in edit mode with a saved sound comment available, you can delete or start a new recording if necessary.

While viewing, you can tap the “Time” command under the “Measurements” section to filter data by a corresponding part of a date and time. The new window appears in which, by analogy to a dose search, you should specify the duration of time to graph measurements for.

A measurement graph is another function that opens as you tap the “Graph” command under the “Measurement” section. This graph is similar to a dose graph with only difference – the measurements themselves are shown as the dots.

4.6 Settings

 

Settings provide a variety of functions, such as:

 

·        setting threshold values of accumulated dose;

·        setting threshold values of dose rate;

·        setting a language for the GS Ecotest” user interface;

To create a new threshold, enter edit mode by tapping Edit and then selecting the “Add threshold” command (the 6 button). After a new window appears, the user may enter a name (identifier) of a new threshold (optionally), specify a numeric value of a new threshold in mSv; set a vibration/sound alert (if necessary), which might go off if the accumulated dose is over the specified threshold value; select the “Save” command.

 

To view and edit already created thresholds, tap the Done button. To edit the existing threshold, choose a necessary one from the list. A new window for editing the specified threshold appears in which the user can change a name (identifier) of the existing threshold, a threshold value, and set a vibration/sound alert. Changes the user made will not take effect until the “Save” command is selected.

 

4.6.2 γ Thresholds

This function enables the user to create new dose rate threshold levels and choose which existing ones to edit. After the γ thresholds function is selected, a new window appears, displaying a list of previously saved gamma thresholds. If there are no gamma thresholds, the list will be empty. Each record in this list consists of a description of one gamma threshold, its identifier (name) and numeric value. In this window the user can also create a new gamma threshold, edit parameters of the existing threshold, or choose which one to delete (the 5 button).

 

To create a new threshold, enter edit mode by tapping the Edit button and then by selecting the “Add threshold” command (the 6 button). After a new window appears, the user may enter a name (identifier) of a new threshold (optionally), specify a numeric value of a new threshold in μSv/h; set a vibration/sound alert (if necessary), which might go off if the dose rate exceeds the specified threshold value; select the “Save” command.

 

To edit the existing threshold, switch to the viewing mode with a click of the Done button and choose a necessary one from the list. A new window for editing the specified threshold appears in which the user can change a name (identifier) of the existing threshold, a threshold value, and set a vibration/sound alert. Changes the user made will not take effect until the “Save” command is selected.

 

4.6.3 Language

 

All languages available in the GS Ecotest” user interface are listed in the Language settings screen. The user may change a language of the application interface by tapping a necessary record in the list. A check mark shows which language is currently being used in the application.

 

4.6.4 Facebook

 

The Facebook feature on your iOS device indicates whether or not the application is connected to a social network. There are two available conditions – “Sign in” and “Sign out”. As the user clicks Sign in, the application signs in to Facebook for further use. Tapping the Sign out button disconnects the current user from the application.

 

4.6.5 Twitter

 

The Twitter feature on your iOS device indicates whether or not the application is connected to a social network. You can link a Twitter account to the application on the Settings screen. If the connection is successful, a message, stating “Connected”, appears on the screen. If there are no accounts on the Settings screen, the Sign in button appears. Tap this button to go to the system settings where you can enter information for setting up a Twitter account.

 

4.6.Clearing an ENTIRE database

Do not attempt to select the "Clear database" command while a dosimetric device communicates with the iOS device via the Bluetooth interface.The user will be notified at that in the way of a corresponding interactive message.

 

When the "Clear database" command is selected, the warning message appears, requiring the user to confirm an action to clear all data contained in the database. Clicking Yes will eliminate all data in the database without further restoring. If the user clicks No, all data will remain in the database without changes.

 

4.6.7 Startup animation

A startup animation shows the user how to work with a dosimetric device for data communication with the GS Ecotest application via the Bluetooth interface. The animation appears if the Startup animation menu item is checked on the Settings screen. If there is no check mark, the startup animation will be no longer displayed.

·        setting the iOS device before the first use of the GS Ecotest” application;

·        setting the iOS device before each use of the GS Ecotest” application;

·        web address of a website with more detailed information about the GS Ecotest” application;

·        web address of the “ECOTEST” TM products website.

Requirements and recommendations on setting the iOS device before the first and each use of the GS Ecotest” application are displayed for the user on a separate screen.

 

To go to the above-mentioned websites for getting additional information, tap a necessary link in the Help window.

 

4.7 Social networking integration

The main function of social networks is to let the user share data on radiation measurements with friends on Twitter or Facebook. Two buttons for each social network are at the top of the point view screen.

To tweet a radiation measurement, tap Twitter at the top of the screen. If the application is not connected to any account, you will be notified of that by a related message.

If the connection is made, tap twitter_button to open a screen shown below. The screen consists of an upper pane, showing the Cancel (to the left) and Send (to the right) buttons, and the message body, displaying the From field, the text of a message, the Add photo button and the number of available characters. Tap the From field to choose the account for sending a Tweet (in case of multiple accounts).

The text of a message includes a phrase, such as "Radiation at point: 0.460 μSv/h.", and a text that the user can edit. Please note that Tweets should not exceed 140 characters in length. The number in the lower-right corner of the Tweet screen shows the number of characters remaining to enter.

A message can be sent with an attached photo. To send a photo, a photo comment should be attached to a point. The screenshot below illustrates the disabled Add photo button, which means that only the text message is sent.

If the point includes saved coordinates, a Tweet is sent with these tagged data.

Help_Screen_13_eng

To share measurement data with friends on Facebook, tap facebook_button at the top of the point view screen. If there are no connected accounts, the application, by analogy with Twitter, allows the user to create a Facebook account.

A screen for sending a text message to Facebook is similar to the Twitter screen. The difference is that there is no limit on characters to be entered and no choice of active accounts. Similarly, the text of a message consists of a phrase (see screenshot below “I found radiation 0.460 μSv/h at latitude 23.4000 and longitude 49.2000.”) and a text the user can enter (as shown in the screenshot below “My custom text”).

 

If the message is sent with a photo comment, the Facebook app creates a “GS Ecotest” album for your profile where an image will be sent.

 

If you are within a distance of 100 m from a spot that Facebook knows, a marker pin will be automatically dropped at that location.

4.8 Backing up

The application’s Backup feature is provided via the File Sharing section in the iTunes app. You can copy the database from your iOS device to your PC (with iTunes installed) and vice versa. Follow these steps to access backup data:

1.     Select your iOS device from the Devices section of iTunes.

2.     Сlick the Apps tab.

3.     Choose the “GS Ecotest” application under the File Sharing section at the bottom of the screen.

4.     Find all files associated with the application in the Documents list.

The screenshot below shows which files can be accessed:

To copy a file, simply drag and drop it into the Documents list or tap the Save to button.

 

Deleting these files (except xml files) is not recommended if you are not sure whether this violates the database integrity.
