Karl E. Huggins
Karl E. Huggins is an American decompression researcher and author of a set of air decompression tables for reduced risk and multi-level repetitive diving based on the US Navy tables modified to avoid Doppler ultrasound detectable vascular bubble production. He developed the algorithm used by the first commercially successful microprocessor-based decompression computer, the Orca Edge, based on the US Navy decompression algorithm derived by Robert D. Workman (decompression researcher), Robert D. Workman, but taking all six tissue compartments (not just the 120 minute compartment) into account when calculating residual nitrogen for multi-level and repetitive dives. Education Huggins enrolled in Biological Oceanography at the University of Michigan, Ann Arbor, MI, with courses in aquatic leadership. During this period, he took a course in scuba diving under Lee Somers in 1976, followed by further training in underwater technology and chamber operations. While on the underwater technol ...

Decompression Table
The practice of decompression by divers comprises the planning and monitoring of the profile indicated by the algorithms or tables of the chosen decompression model, to allow asymptomatic and harmless release of excess inert gases dissolved in the tissues as a result of breathing at ambient pressures greater than surface atmospheric pressure, the equipment available and appropriate to the circumstances of the dive, and the procedures authorized for the equipment and profile to be used. There is a large range of options in all of these aspects. Decompression may be continuous or staged, where the ascent is interrupted by stops at regular depth intervals, but the entire ascent is part of the decompression, and ascent rate can be critical to harmless elimination of inert gas. What is commonly known as no-decompression diving, or more accurately no-stop decompression, relies on limiting ascent rate for avoidance of excessive bubble formation. Staged decompression may include deep st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orca Edge
The Orca Edge was the first commercially viable recreational diving personal decompression computer. The Orca Edge was an early example of a dive computer that ran a real time algorithm. Designed by Craig Barshinger, Karl E. Huggins Karl E. Huggins is an American decompression researcher and author of a set of air decompression tables for reduced risk and multi-level repetitive diving based on the US Navy tables modified to avoid Doppler ultrasound detectable vascular bubble ... and Paul Heinmiller, the Edge did not display a decompression plan, but instead showed the ceiling or the so-called "safe-ascent-depth" and a graphic display of calculated tissue gas loadings. A drawback was that if the diver was faced by a ceiling, he did not know how long he would have to decompress. The Edge's large, unique display, however, featuring 12 tissue bars permitted experienced users to make a reasonable estimate of their decompression obligation. In the 1980s the relevant technology i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
US Navy Decompression Algorithm
The United States of America (USA), also known as the United States (U.S.) or America, is a country primarily located in North America. It is a federal republic of 50 states and Washington, D.C., its federal capital district. The 48 contiguous states border Canada to the north and Mexico to the south, with the semi-exclavic state of Alaska in the northwest and the archipelagic state of Hawaii in the Pacific Ocean. Within the U.S. are 574 federally recognized tribal governments and 326 Indian reservations with tribal sovereignty rights. The U.S. asserts sovereignty over five major island territories and various uninhabited islands. It is a megadiverse country, with the world's third-largest land area and third-largest population, exceeding 340 million. Paleo-Indians migrated to North America across the Bering land bridge more than 12,000 years ago, and formed various civilizations and societies. Spanish exploration and colonization led to the establishment in 1513 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
