Emitters specifically for sub-sea applications

A method for alleviating impact of pressure on a submersible device, comprising:

• providing a casing as part of the submersible device;
• filling an interior space of the casing with fluid;
• and
• sealing the casing so that water cannot get into the casing and so that the fluid cannot get out of the casing.

A method for alleviating impact of pressure on a submersible device, comprising:

• providing a casing as part of the submersible device;
• filling an interior space of the casing with fluid;
• providing a bladder that is coupled to the casing to permit a flow of the fluid from and to the interior space of the casing;
• and
• sealing the casing so that water cannot get into the casing and so that the fluid cannot get out of the casing except into the bladder.

A method for alleviating impact of underwater pressure on an emitter device, comprising:

• providing a casing of the emitter device;
• providing a power source;
• providing an emitter that is coupled to the power source;
• filling an interior space of the casing with fluid;
• providing an antenna that is coupled to the emitter;
• providing a bladder;
• positioning the antenna so that the antenna is positioned within the bladder so that the fluid can flow from and to the interior space of the casing;
• and
• sealing the casing so that water cannot get into the casing and so that the fluid cannot get out of the casing except into the bladder.
