Patent ID: 6931348

Claim:
A data processing apparatus for divers comprising: a computing means for repeatedly calculating, for a predefined group of tissue compartments, a non-decompression limit for each tissue compartment based on a determination of an amount of inert gas accumulated in vivo in said tissue compartments; and a determination means for determining a tissue-compartment-computing-sequence specifying an order sequence according to which said computing means calculates the non-decompression limit of each tissue compartment; wherein: each of said tissue compartments is characterized by a saturation half-time parameter; said computing device repeatedly cycles through said tissue compartments and sequentially calculates the non-decompression limit of each tissue compartment during each cycle by implementing a separate computing process for each tissue compartment, in sequence, as determined by said tissue-compartment-computing-sequence; said determination means arranges said tissue compartments within said tissue-compartment-computing-sequence in ascending order based on the absolute value of the difference between the saturation half-time of each tissue compartment during a current cycle and the saturation half-time of the tissue compartment that had the lowest calculated non-decompression limit during the previous cycle as determined by the computing means.
