First aid: artificial breathing(mouth to mouth)

1

In case of electric shock you have to ensure the first aids to the patient, but to do this you have to consider two very important things: - interrupt immediately the electric circuit; - if the circuit has not been interrupted, do not touch the patient with bare hands;

After doing this, without delay contact the nearest mobile unit of first aid and practice to the patient, in case of loss of consciousness, the breathing mouth to mouth as described below.

2

Put the patient lying on his back with the arms parallel to the body, ensure that he does not have the breathing tracts obstructed (chewing-gum, dental prosthesis, etc.), otherwise set him free from foreign bodies. Kneel near the patient’s head and putting a hand under his neck, incline as possible his/her head backwards.

3

Going on with keeping the patient’s head inclined with one hand, use the other one to occlude the nostrils, if you are going to practise the breathing through the oral cavity, or occlude the mouth if you want to do it through the nasal cavity. While doing this begin the auto-oxygenation, with deep breathing. Then practice the artificial breathing blowing in the chosen cavity beginning with ten expirations each minute to go on them with twelve and fifteen.

4 During the breathing procedure you have to control that the patient’s chest dilates, otherwise change cavity where to blow the air because the previous one could be obstructed.

5 Do not ever stop the artificial breathing until the patient has recovered or the first aid unit has come.

1. GENERAL DESCRIPTION

The EK-DCS/1 board allows to decodes a video signal plus two audio channels in according to MPEG-2 specific (Main profile@ Main level 4:2:0) and (Main profile@ Main level 4:2:2) The incoming transport stream could come from three different inputs:

- BNC ASI input placed on the panel (see chapter 2), - INT MPX internal input, - INT DEC internal input,

At the power-off or if the board in not running correctly the ASI IN is routed thru mechanical switch directly to ASI out, during normal running the ASI out is the re-clocked ASI in. The internal inputs allow to feed the decoder transport stream input with streams incoming from other boards in the EK-MFR/1. The decoder decodes video, audio and teletext according to Video Audio and TTX settled PID, in case of absence of everyone of this packets or PCR packet or PES corruption an alarm is displayed. The MPEG2 decoder video output is processed to put black field in case of decoding failure and it is also possible to add CCIR 17 test signal on every line between 7 to 22 and 320 to 335. At the video digital to analogue converter it is added the ttx data if present on the transport stream at the selected pin. The decoder video output can be settled between the RS170 and SDI. The decoder Audio output is in analog, AES/EBU on the same connector and is embedded on the SDI port in Group 0 Channel 1 and 2. A video input and an audio input are present to allow redundancy with others backup signal, if the bypass is enabled from the menu, in case of fault or transport stream decoding problem the incoming video and audio are routed directly to the video and audio output.

The example below explains how to set the Decoder In value. The procedure of the variables setting is identical for the other parameter of the board. The Decoder In menu is located in the Setting menu, Port sub-menu (see chapter 3) so when the EK-DCS/1 menu is selected, using the “explore menu” keys (EK-MFR/1 user’s handbook, front panel description), it is possible to run until the Settings menu as the following figure shows: Pushing the “enter” key (EK-MFR/1 user’s handbook, board panel description) it is possible to explore the Port internal menu and so it is possible to see the actual Decoder In parameter: Now, pushing the “enter” key and using the “modifying variable” keys ,it is possible to change the Decoder In value. We suppose to set the Int Dec value. To do this the user must press the “enter” key first and then, using the “modifying variable” keys, to choose the new value to set. When the value is selected, to confirm it to press again the “enter” key. The new value is loaded and the display shows:

Eurotek s.r.l.

If, after the change, the user press the “escape” key (EK-MFR/1 user’s handbook, board panel description), the display returns the previous value (in the example Asi In).

4. WEB PAGE The EK-DCS/1 board is supplied of a web page that allows to obtain a complete view of the status of the board variables. When the EK-MFR/1 system is connected to a terminal unit (PC) and the web pages of the system are loaded (EK-MFR/1 user ‘s handbook, web interface chapter), the user can see the following EK-MFR/1 main web page:

The EK-DCS/1 board is loaded in the slot number four; to visualize the web page of the board is necessary to move, using a mouse, the cursor on the slot associated to the board (slot 4) and then, to click the left mouse button on its. So we obtain the following image:

EK-DCS/1 Arch 3193 Rev. A of 07/05/2010

Pag. 19 of 23 601-000192/MN

Eurotek s.r.l.

The web page of the EK-DCS/1 board is showed above. In the top section, are reported the version of the software tool (v 1.1) and the name of the board with the associated slot number (slot 4 = => EK-DCS/1). Under the name, of the board, are indicated every menu in dark colour, while the selected menu is in light colour and its variables are displayed on the centre of the page. The down side of the page is featured by the following parameter: the refresh time variable allows to set the useful time to confirm the setting of a menu variable. The time to new refresh windows gives information about the countdown of the refresh time. The Set parameter box allows to confirm the setting of a menu variable. The output console line with the status square are used to obtain a view of the alarm conditions of the entire system. During the normal working conditions, the output console line returns the No Alarm value; if an alarm is in progress, the following message appears: <<Alarm Active. “n” variables in alarm>>, where n is the number of the variables in alarm. When a menu variable is affected by an alarm, the value of the variable, in the related window, is showed in red colour and also the name of the board became red.

The next example shows how to change a menu variable. The procedure to set every variable value is similar to this. We suppose to set the Standard parameter to NTSC. The Standard parameter, is located in the Settings menu, under the Decoder sub-menu:

Moving the cursor, using a mouse, on the Standard box and pushing the left mouse button on the black indicator, the user can see the available value for the Standard variable setting:

EK-DCS/1 Arch 3193 Rev. A of 07/05/2010

Pag. 21 of 23 601-000192/MN

Eurotek s.r.l.

To select the NTSC parameter, to move the cursor on the NTSC label, and to push the left mouse button. The NTSC appears in the Standard box like the following image shows:

EK-DCS/1 Arch.3193 Rev. A of 07/05/2010

Pag. 22 of 23 601-000192/MN

Eurotek s.r.l.

We have settled, for example, the refresh time parameter on the 30 seconds indicator, so every thirty seconds the system variables are refreshed. When the refresh countdown is complete the refresh label is flashing. When a new value is loaded in the variable window (in the example Standard = NTSC) the user has then seconds for to confirm the value pushing, using the left mouse button, the Set box (a message is showed on the output console line). At the end of the then seconds, if the refresh time is not finished, it is again possible pushing the set box (you can still press set (until new refresh occurs) message is showed on the output console line); if also the refresh time is at the end, the system reloaded the previous variable value. When the settings operations are complete, the new loaded value is visible on the EK-MFR/1 display.
