INFORMATION SYSTEM FOR DIVER Russian patent published in 2003 - IPC

FIELD: measurement technology. SUBSTANCE: proposed system makes it possible to detect defects in decompression modes in raising the diver. Proposed system includes hydrostatic pressure converter made in form of fiber-optics Maxh-Zehnder interferometer whose signal coil is brought in contact with water medium and bearing fibers coil is isolated from it; system includes also amplifier, indicators and register, comparison unit, alarm signal shaper and reference frequency unit. System is additionally provided with analog interferometer but its coils have different number of turns in signal and bearing fibers coils. EFFECT: possibility of obtaining optical signals at system output proportional to diving depth and rate of raising diver. 2 cl, 1 dwg
