Abstract
The invention relates to a method and system in connection with a wristop diving computer (1). According to the method, at least the pressure of a gas bottle (2) is measured and the pressure data is transmitted under water using a low first frequency f1 to a wristop computer (1). According to the invention, on the surface of the water a second frequency f2, higher than the first frequency f1, is used for two-way telecommunications between the gas bottle (2) and the wristop computer (1).
Claims28
A method in connection with a wristop diving computer for use by a diver, the method including the steps of:
- measuring at least the pressure of a gas-bottle;
- transmitting the pressure data under water at a low first frequency f1 to the wristop computer;
- and
- using on the surface of the water a second frequency f2 that is higher than the first frequency f1 for two-way telecommunications between the gas bottle and the wristop computer.
A wristop diving computer system configured for operation above and below the surface of a body of water, the system comprising:
- a central unit;
- a telecommunications element operably coupled to the central unit, the telecommunications element configured to receive a first electromagnetic frequency f1 at least when below the surface of the water;
- and
- a telecommunications transceiver operably coupled to the central unit and configured to operate at a second frequency f2, higher than the first frequency f1, in two directions, particularly for telecommunications taking place above water.
A telecommunications device for communicating the pressure within at least one gas bottle above or below the surface of a body of water, the device comprising:
- a central unit;
- a telecommunications element operably coupled to the central unit, the telecommunications element configured to transmitting a first frequency f1 at least when below the surface of the water;
- and
- a telecommunications transceiver operably coupled to the central unit and configured to operate at a second frequency f2, higher than the first frequency f1, in two directions, particularly for telecommunications taking place above water.
