摘要： An analog apparatus for determining the velocity of sound at a selected position in a liquid media is provided with a means for representing the conductivity, temperature, and depth of the position in the form of analog voltages, and is further provided with an analog calculating means receiving each of the voltages for calculating the velocity of sound as a function of conductivity, temperature, and depth. The sound velocity may be calculated at a succession of positions to provide a sound velocity versus depth profile of the liquid media.

摘要： An improved method and apparatus for processing electronic signals for usen establishing an improved image display includes storing the electronic and acoustic response of all the detectors in response to impingement thereon by a plane wave-front as stored in a memory. In the operational environment, these stored signals are combined with the transducer response and the signals are combined in such a fashion as to compensate for spatial nonuniformities.
