1. An underwater transmitter/receiver assembly for use with a self-contained underwater breathing apparatus including a breathing gas tank and a diver'"'"'s face mask, the assembly comprising:
- transmitting circuit means attachable to said tank and including sensor means for providing output signals indicative of variable actual dive parameters, a modulator for modulating said output signals, and a transmitting circuit for propagating a modulated carrier wave representative of a respective one of said output signals; and
means for providing information on variable dive parameters to an individual diver wearing said face mask, said information providing means being formed as a single unit attachable to said face mask and including a receiver circuit which is physically disconnected from said transmitting circuit means and receives therefrom said modulated carrier wave, a demodulator for demodulating said carrier wave, a display device for providing a visual display indicative of a respective variable dive parameter, and an imaging system providing an image of the display which is focussed in the line of sight of the diver wearing the face mask when said unit is attached thereto.

Abstract
A dive parameter transmitter/receiver assembly for scuba diving includes a transmitter circuit with a control unit with one or more sensors for detecting dive parameters and/or information to be displayed. A modulator is included for modulating the parameter(s) or information and a transmitting transducer for propagating the parameter(s) or information. A receiver circuit is included and has a receiver transducer, a demodulator, a decoder, and a display for displaying the parameter(s) or information.
