TWO-CHANNEL EMERGENCY BEACON FOR UNDERWATER MANNED APPARATUS Russian patent published in 2020 - IPC G01S15/00 

FIELD: vessels and other watercrafts.

SUBSTANCE: invention relates to mounted on habitable underwater vehicles equipment for generating special signals emitted into an aqueous or (and) air environment, with information on fact, time and nature of accident with carrier of said facility, as well as its location. Technical result is achieved by that, first, in on-board elements of prototype device, more specifically temperature, water and radiation sensors, included is a sensor for chemical composition of air inside the underwater object and, secondly, the electronic components of the main on-board part of the device include a transceiving hydroacoustic channel with audio communication elements (microphone-telephone unit MTU), as well as reception-transmission modes operating switches, and the autonomous overboard part - receiving-emitting radio and hydroacoustic units, reception-transmission mode switches with radio and hydroacoustic antennas, which enable to realize the possibility of installation of two-way simplex connection of crew members of emergency apparatus and rescue forces.

EFFECT: elimination of shortage of analogues and a prototype, namely providing leading search of forces and means with more complete information on causes of accident, technical state of emergency facility in real time, as well as automation of this process and implementation of possibility of installation of single- or double-sided hydro-radio contact.
