Diving information processing device, control method for a diving information processing device, and a control program

A control method for a diving information processing device, comprising the steps of:

• measuring ambient pressure, with a pressure measuring unit;
• measuring elapsed time, with a timekeeping unit;
• detecting an in-water condition, with a water entry detection unit;
• calculating tissue absorption/elimination of inert gas with a safety information derivation unit based on the pressure and the elapsed time while diving;
• determining that a diver is diving when an in-water condition is detected and the water depth corresponding to the pressure measured by the pressure measuring unit is deeper than a predetermined diving evaluation depth;
• recording the water depth corresponding to the pressure measured by the pressure measuring unit together with the elapsed time during a dive;
• detecting travel at a high altitude based on water entry detection by the water entry detection unit when the pressure measured by the pressure measuring unit is lower than a predetermined atmospheric reference pressure;
• and
• cancelling recording by the depth recording step when high altitude travel is detected.

A computer-readable medium having stored a control program for controlling a diving information processing device, the control program for performing the steps of:

• measuring ambient pressure, with a pressure measuring unit;
• measuring elapsed time, with a timekeeping unit;
• detecting an in-water condition with a water entry detection unit;
• calculating tissue absorption/elimination of inert gas with a safety information derivation unit based on the pressure and the elapsed time while diving;
