Field of view underwater diving computer monitoring and display system

Abstract

A system for conveying information to an underwater diver wearing a mask. The information is conveyed via a field of view display system which places the information at the glance of the diver through the viewing window of the diving mask. 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 processes the sensed information and displays it to the diver as well as interpreting the information to provide advice such as safe assent rates which will allow the diver to avoid decompression sickness and the remaining safe dive time. The display placed within the field of view desirably includes an optical arrangement for placing an image of a visual array at a long focus distance, preferably at infinity, in relation to the eye of the diver and for magnifying the actual image of the visual array means such that the diver can readily observe the image of the visual array. The present invention keeps the diver informed of important information without the diver's attention being diverted from the surrounding environment and without requiring additional movement or effort from the diver.
