AI Technical Summary

Benefits of technology

The system provides accurate underwater location determination and path tracking, allowing divers to efficiently navigate and revisit points of interest by combining GPS data with depth and time measurements, enhancing navigation and exploration capabilities.

Problems solved by technology

A problem commonly encountered by divers is an inability to accurately locate position underwater.
However, depth alone is insufficient to locate the position of a diver during a dive.

Embodiment Construction

[0028]Referring now to the drawings, dive computers in accordance with practice of the present invention are illustrated. The dive computers make and record at least three significant sets of measurements, which enable the estimation of the location of points of interest underwater and the path traveled by a diver during a dive. The first set of measurements typically includes measurements of latitude, longitude and time immediately prior to the commencement of a dive. The second set of measurements can be generated by periodically measuring depth and time during a dive. The third set of measurements can be compiled by measuring latitude, longitude and time immediately upon resurfacing from a dive. Following a dive, an estimation of location at a specified time during the dive using these three sets of measurements can be made by using a number of techniques in accordance with practice of the present invention. In several embodiments, the accuracy of the estimation can be increased ...

Description

CROSS-REFERENCE TO RELATED APPLICATION(S)[0001]This application is a divisional of U.S. patent application Ser. No. 11 / 264,290, filed Oct. 31, 2005, which is a continuation application of U.S. patent application Ser. No. 10 / 615,635, filed Jul. 8, 2003, entitled DIVE COMPUTER WITH GLOBAL POSITIONING SYSTEM RECEIVER, now U.S. Pat. No. 6,972,715, which claims priority of U.S. Provisional Application No. 60 / 394,982, filed Jul. 8, 2002, the contents of which are expressly incorporated herein in their entirety.FIELD OF INVENTION[0002]The present invention relates generally to underwater exploration and more specifically to apparatus and techniques for determining location during a dive.BACKGROUND OF THE INVENTION[0003]The development of self-contained breathing systems has enabled humans to dive and remain underwater for several hours. The ability to remain underwater for an extended period of time can enable divers to reach considerable depths and cover expansive distances in exploring u...
