Diving information processing device, control method for a diving information processing device, and a control program

If the diving mode is erroneously entered while travelling at a high altitude, such as when flying in an airplane, the error is detected so that calculating tissue in / out-gassing of inert gases continues. The control unit 50 of the dive computer records the water depth corresponding to the pressure measured by the depth measuring unit 61 together with the elapsed time, determines if the user is moving in a low pressure region based on water entry detection by a water entry detection unit and the depth detected by the depth measuring unit 61, and if the user is determined to be travelling in a low pressure region cancels measuring the water depth, cancels the wrongly selected operating mode, and changes from the operating mode used when diving to an operating used when not diving.

Method for detecting the start of a dive for a dive computer

The present invention provides a method for detecting the start of a dive for implementation in a portable electronic device (1) of the dive computer type. More specifically, the method is to be implemented in a device of this type having at least one first operating mode and one second operating mode, called the dive mode. This device comprises in particular a pressure sensor (5) for measuring the value of the ambient pressure (P) as well as electronic circuits (2) for processing the pressure measurement results comprising a time base (4) and at least one memory zone (7, 8). The detection method according to the present invention more specifically provides for the reference pressure value (Pref) to be updated on the basis of the ambient pressure (P) measurements, this value being used to detect the start of a dive. In certain particular conditions, the method according to the present invention suspects the start of a dive, in which case it backs up the value (Psauv) of the reference pressure (Pref) stored before updating. If the start of a dive is confirmed after having been suspected, the reference pressure value (Pref) stored is replaced by the backed up value (Psauv) upon activation of the dive mode.

Dive computer and method for determining gas formation

The invention disclosed herein employs an algorithm, the Gas Formation Model (“GFM”), to calculate the formation of free gas in a human body. The GFM is based on a novel theory of the formation of free gas relative to the physiology of the human cardiovascular system. Additionally, the GFM utilizes a novel means for the solution of integro-differential equations, the type of equations that derive from the introduction of physiological parameters. GFM-based dive computers utilize novel inputs, including a measure of exercise at depth to reflect the state of an individual's cardiovascular system. GFM-based dive computers also produce novel outputs, including the actual volume of free gas present in a diver's cardiovascular system. The GFM is implemented as a practical computational tool by means of a incorporating the algorithm into a dive computer.
