A dive computer, personal decompression computer or decompression meter is a device used by an underwater diver to measure the elapsed time and depth during a dive and use this data to calculate and display an ascent profile which, according to the programmed decompression algorithm, will give a low risk of decompression sickness.
In 1979 on a diving trip to the Bahamas, he was introduced to the concept of multi-level diving and the technique of repet-up s, which was in use by commercial divers as a way to make more effective use of the Navy tables for multi-level diving, though there were some theoretical uncertainties with the system, as the Navy tables of the time used six tissue compartments, but only considered the ...
The personal decompression computer, or dive computer, is a small computer designed to be worn by a diver during a dive, with a pressure sensor and an electronic timer mounted in a waterproof and pressure resistant housing and which has been programmed to model the inert gas loading of the diver's tissues in real time during a dive.

Carpenter was trained by Robert A. Barth. Shortly before the experiment took place, Carpenter had a scooter accident on Bermuda and broke a few bones. The crash ruined his chances of making the dive. [5] SEALAB I is on display at the Man in the Sea Museum, in Panama City Beach, Florida, near where it was initially tested offshore before being ...
The Orca Edge was an early example of a dive computer that ran a real time algorithm. [2] Designed by Craig Barshinger , Karl E. Huggins 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.
The Bühlmann decompression model is a neo-Haldanian model which uses Haldane's or Schreiner's formula for inert gas uptake, a linear expression for tolerated inert gas pressure coupled with a simple parameterised expression for alveolar inert gas pressure and expressions for combining Nitrogen and Helium parameters to model the way inert gases enter and leave the human body as the ambient ...
The US Navy has used several decompression models from which their published decompression tables and authorized diving computer algorithms have been derived. The original C&R tables used a classic multiple independent parallel compartment model based on the work of J.S.Haldane in England in the early 20th century, using a critical ratio exponential ingassing and outgassing model.
