    摘要: A recoverable underwater acoustic beacon having a magnetic latch holds a marker buoy captive while submerged. The acoustic beacon sends out pulses of underwater sound so that it can be located and also has receiving means to detect a momentary continuous wave (CW) release command signal during the periods between pulses. A current flows through a neutralizing coil within the acoustic beacon when the CW release command signal is received. The neutralizing coil establishes a magnetic field through the beacon''s non-magnetic shell to neutralize the magnetic field of an external permanent magnet and, through an associated leverage form of latch, releases the marker buoy to rise to the water surface on the end of a recovery cable.
