Purpose:
The device is designed for protection from dictaphones and «bugs» during private conversation.
Application:
Structurally, the UDS contains the ultrasound emitter on the back panel and the acoustic emitter on the top panel of the device
The premises owner sets the device in such a way that the ultrasound emitter is directed towards an interlocutor. During a conversation the owner warns the interlocutor about importance of subject of negotiations and turns on the UDS. The acoustic emitter generates speech-like interference blocking the conversation of the interlocutors. The ultrasound emitter forms ultrasound flow which decreases a sensitivity of microphone in the interlocutor's mobile phone.
Most modern mobile phones (Samsung, iPhone, etc.) will be suppressed in «quiet mode» - without activation of acoustic interference. However, the suppression of the other phones is only possible with the simultaneous using of acoustic and ultrasound interferences.
If a conversation is among people trusting each other, the device UDS is set away from a negotiating table. The level of the acoustic noise is adjusted so that the dictaphones, installed outside of the negotiating table, are unable to record the conversation. The ultrasound emitter should be directed towards the nearest wall.
The device can operate both autonomously and by charger supplied in a package. The complete package also includes a cover for carrying of the device.
The storage battery charge level is indicated by the led above the charging socket. After the storage battery is fully charged the led red color will change to green one.
