摘要： The secure communication keying system has a noise generator whose output a predetermined finite band of noise within, for example, the zero to eleven hundred cycle per second range. The noise generator may be a pseudorandom noise generator that is synchronized with a given clock frequency. The output of the system may have noise-like characteristics, but it is encoded with any type of intelligence desired to be transmitted. The output signals simulate the ambient noise occurring within the communication medium and has the same frequency spectrum regardless of the frequency of the modulating signals supplied thereto.

摘要： A multiple anchor marine mooring system wherein a plurality of anchors capable of stably gliding through water at a fixed depression once a minimum glide velocity is attained are secured to a carrier in a compact cluster. The cluster is configured so that gravity alone will accelerate it in water to glide velocity, whereupon the anchors are automatically released for self-emplacement.
