Definitions

  • the present invention relates to a dive computer, which is set up to be carried along by divers in dives, which comprises at least one measuring device, at least one memory device, at least one computing device, at least one data transmission device and a display device.
  • Dive sites in resort areas or diving schools often have a large number of dive computers. These will be made available to the participants of organized group dives or individual dive groups. Dive computers assist divers in performing dives and especially in avoiding decompression problems. During the dive the diving depth and the dive time are continuously recorded and at least a value for the nitrogen saturation in the body of the diver is calculated. A rise time determined therefrom with the number of required decompression stops with their respective diving depth are usually displayed to the diver as well as detected environmental values or the residual air quantity in his compressed air tank. Dive computers available on the market are configured to continue the computation of nitrogen desaturation of the diver's tissues to complete desaturation, for example, to incorporate an existing residual saturation of the diver's tissues in a subsequent dive into the further nitrogen saturation calculation. Even at low ambient pressure outside of the water after a dive decompression problems may occur such. B. when using an aircraft. It makes sense that divers therefore carry the dive computer with them until the desaturation calculation is completed. For timely lending a dive computer to several divers offer some
  • Dive computer models the ability to cancel a running desaturation calculation and start a new one. If a previous diver whose computation was aborted starts another dive before his body is completely desaturated, the saturation values computed by a dive computer deviate from the actual values, which can lead to a critical situation for that diver.
