Field of view underwater dive computer system

摘要

A system for conveying information to an underwater diver wearing a mask. The information is conveyed via a field of view display system which either superimposes the information onto the field of view of the diver or places the information within a glance of the diver. Included are sensors for measuring the pressure in the dive tanks, for sensing the depth of the diver, and for sensing the ambient temperature of the surrounding environment. A microcomputer interprets the information to provide advice such as safe assent rates. The display desirably includes a visual array for providing a visually perceptible representation of the information conveyed by the display signal as well as an optical arrangement for placing an image of the visual array at a long focus distance in relation to the eye of the diver and for magnifying the actual image of the visual array.
