Diver's information display device

A diver's information display device that displays a time instant indication, a diving situation indication, which indicates a diving situation of a wearer of the display device, a physical indication, which indicates a physical condition change that is attributable to the wearer diving and is calculated based on the diving situation, and a diving schedule indication, which indicates information that assists the wearer in planning a preferable diving schedule according to the physical indication, the diver's information display device comprising:

• a dive history memory means for storing a dive history of a wearer's past dives;
• first and second external manipulation members;
• a display means for displaying in a time mode, in which a time instant indication is displayed, in a plan and surface mode, in which a physical indication and a diving schedule indication are displayed, a dive mode, in which a diving situation indication is displayed, and a log mode, in which said dive history is retrieved and displayed;
• wherein said time mode, plan and surface mode, and log mode each comprise one of three display modes that are changed one to another;
• and,
• a mode changing means that is responsive to manipulation of said first external manipulation member for changing one of two display modes, other than a first display mode, to the first display mode;
• and said mode changing means is responsive to manipulation of said second external manipulation member for changing one two display modes, other than a second display mode, to the second display mode.

A method of controlling a diver's information display device that displays a diving situation indication, which indicates a diving situation of a wearer of the display device, a physical indication, which indicates a physical condition change that is attributable to the wearer diving and is calculated based on the diving situation, and a diving schedule indication, which indicates information that assists the wearer in planning a preferable diving schedule according to the physical indication, the method comprising:

• displaying a physical indication and a diving schedule indication in a plan and surface mode, and displaying a diving situation indication in a dive mode;
• automatically changing from displaying in said plan and surface mode to displaying in said dive mode when diving is started in said plan and surface mode;
• and
• automatically changing from displaying in said dive mode to displaying in said plan and surface mode when diving is terminated or suspended.
