Cocon-DS

The principle of operation is based upon the remote control of phone’s energy activity. In a standby mode the activity is minimal. The functioning of any application of the phone results in a change of energy state, which is indicated with relevant sensors and activates the mechanism of acoustic protection. This principle allows protection of any mobile phone from remote activation (incl. the activated “Dictaphone” function).

Once the switch is «on» (pic. 1) a short sound proceeds, which means the device is ready to use. The activation of acoustic noise generator indicates the unsanctioned connection to the phone and the initialization of informational exchange. Intellectual mode is realized so that after the communication session starts, the noise generator switches on with a delay (5-10 sec. approx.), which is enough to hear standard sound signals (dial tone) and accept the call. When pushing the button (pic. 2) the acoustic interference switches off and device goes to indication mode, signalizing about the activity with built-in diode.
