Dive computers with multiple diving modes
First Claim
1. A dive computer, comprising:
- a processor;
memory in communication with the processor;
a pressure transducer in communication with the processor;
a display in communication with the processor;
an input device in communication with the processor; and
clock circuitry in communication with the processor;
wherein the dive computer can operate in a plurality of modes comprising a first operating mode and a second operating mode;
wherein the first operating mode is distinct from the second operating mode;
wherein the processor;
sets the dive computer to operate in the first operating mode;
measures depth information in the first operating mode using the pressure transducer while the dive computer is underwater;
measures time information in the first operating mode using the clock circuitry;
calculates nitrogen loading using a decompression algorithm based on the depth information and the time information while the dive computer is in the first operating mode;
sets the dive computer to operate in the second operating mode in response to receiving input data from the input device;
measures depth information in the second operating mode using the pressure transducer while the dive computer is underwater;
measures time information in the second operating mode using the clock circuitryrecalculates the nitrogen loading using the decompression algorithm based on the depth information and time information measured in the second operating mode and the nitrogen loading calculated in the first operating mode;
generates a set of decompression stops based on the recalculated nitrogen loading; and
displays the set of decompression stops using the display.

Abstract
A dive computer with a free dive mode and/or wireless data transmission capabilities. In one embodiment the invention relates to a diving apparatus including a dive computer having a free dive mode, where the dive computer is configured to calculate a nitrogen loading in the free dive mode using a default value which is the fraction of oxygen in air, and where the free dive mode is used when a diver makes a dive without a self-contained underwater breathing apparatus. Another embodiment includes a method of operating a dive computer including recording two or more first identifiers, receiving pressure information from two or more pressure transmitters, the pressure information comprising second identifiers and pressure measurements, determining whether the pressure information contains one of the two or more first identifiers, and displaying a message indicative of the pressure information that contains one of the two or more first identifiers.
