ABSTRACT:
A dive profile recorder for monitoring conditions encountered by a diver under water includes a plurality of transducers to be carried by a diver for generating electrical signals representative of the conditions encountered by the diver. Encoding circuitry electrically connected to the transducers encodes the electrical signals to form a serial data stream and a transmitter electrically connected to the encoding circuitry transmits the serial data stream through the water. A receiver remote from the diver receives the transmitted serial data stream and decoding circuitry electrically connected to the receiver decodes the serial data stream to electrical signals representative of the conditions encountered by the diver. A display electrically connected to the decoding circuitry receives the electrical signals and displays human-perceptible indicia of the conditions encountered by the diver in response to the received electrical signals.
