ABSTRACT:
A computer-controlled life support system and method for mixed-gas diving, having separate supplies of oxygen and diluent gas or gases is provided. Multiple processor units provide redundant gas control and dive data recording. The primary processor automatically controls the oxygen make-up based on partial pressure of oxygen according previously determined dive parameter. A secondary CPU provides back up gas control information and displays system and dive parameters including decompression schedules. A tertiary CPU, independently powered and provided with duplicate sensors, provides an additional backup means for gas control and decompression calculations. No automatic gas control is available from the third CPU, but displayed data allows manual gas control.
