Signaling beacon using a variable pressure activated porous volume infrared frequency emitter

A signaling beacon comprising:

• a porous media unit configured to allow a fluid to flow there through, the porous media unit including:
• a porous medium configured to allow fluid to flow there through according to at least one fluid flow characteristic;
• a first surface disposed on a first side of the porous medium, the first surface including a plurality of apertures therein that are configured to allow at least a portion of the fluid within the porous media to be selectively exuded onto the first surface or withdrawn from the first surface through the plurality of apertures;
• and
• a second surface disposed on a second side of the porous medium opposite the first surface of the porous medium and configured to selectively receive the fluid input to the porous medium or to receive the fluid withdrawn out of the porous medium;
• and
• a fluid transmission system including:
• a fluid pump configured to selectively cause the fluid to be pumped into or drawn out of the porous medium via the second surface;
• a fluid pressure regulation unit in fluid communication with and disposed between the fluid pump and the second surface, the fluid pressure regulation unit configured to regulate at least one or more of fluid flow, fluid pressure gradients, and volume of the fluid into or out of the porous medium;
• and
• at least one processor configured to control operation of at least the fluid pump according to a predetermined sequence to cause the fluid to be selectively exuded onto or withdrawn from the first surface according to a predetermined modulation pattern;
• wherein at least a portion of the fluid within the porous media to be selectively exuded onto the first surface or withdrawn from the first surface through the plurality of apertures.
