Abstract

A diver'"'"'s computer including detectors for measurement and determination of diving parameters, a processor for processing the measured and determined data, and memory functions for storage of the measured and collected data. According to the invention, the diver'"'"'s computer is provided with a detachable memory unit in which the measured and collected data have been arranged to be stored and which memory unit can be connected to a personal computer or equivalent for analyzing the data. Of the measured and collected data, preferably at least the data on the diving depth, diving time and starting time of the dive, the data on the pressure in the bottle, the situation of residual nitrogen, and possible violations by the diver are preferably stored in the detachable memory unit. The detachable memory unit is preferably user-specific in view of storage of personal data.

Claims

1. In a diver'"'"'s computer having detector means for measuring and determining diving parameters, processor means coupled to said detector means for receiving the measured and determined diving parameters and processing the measured and determined diving parameters, and memory means coupled to said processor means for receiving the measured and determined diving parameters and storing the measured and determined diving parameters, the improvement comprising

said memory means being structured and arranged to be removably coupled to said processor means such that when removed from connection to said processor means, said memory means are connectable to a personal computer for analysis of the measured and determined diving parameters by the personal computer.

2. The diver'"'"'s computer of claim 1, wherein said detector means are structured and arranged to measure and determine at least data on the diving depth, diving time and starting time of a dive, the pressure in a bottle used for the dive, the situation of residual nitrogen, and possible violations by the diver, said detachable memory means being structured and arranged to store the data on the diving depth, the diving time and the starting time of a dive, the pressure in the bottle used for the dive, the situation of residual nitrogen, and possible violations by the diver.

3. The diver'"'"'s computer of claim 1, wherein said detachable memory means is a memory unit which is user-specific, said memory unit storing a particular user'"'"'s personal data including but not limited to a personal setting state, current amount of residual nitrogen, time and date.

4. The diver'"'"'s computer of claim 1, wherein said detachable memory means comprise a memory card.

5. A method for analyzing data relating to diving parameters obtained by a diving computer at a site apart from the diving computer, comprising the steps of:

measuring and determining diving parameters during at least one dive,

processing the measured and determined diving parameters from the at least one dive in a processing unit,

storing the measured and determined diving parameters before and/or after processing in a memory unit removably connected to said processing unit,

detaching said memory unit from said processing unit after said memory unit has stored the measured and determined diving parameters, and

connecting said detached memory unit to a computer for analysis of the measured and determined diving parameters by the computer.

6. The method of claim 5, wherein the step of measuring and determining diving parameters comprises the step of measuring and determining data on the diving depth, diving time and starting time of a dive, the pressure in a bottle used for the dive, the situation of residual nitrogen, and possible violations by the diver.

7. The method of claim 5, further comprising the step of storing a particular user'"'"'s personal data in said memory unit including but not limited to a personal setting state, current amount of residual nitrogen, time and date.

8. The method of claim 5, wherein said memory unit is a memory card.
