  • System for detecting underground objects
    Patent number: 4839654
    Abstract: A system for detecting underground objects which uses reflected wave profile data collected for obtaining a detected image output and subjects the data to a sequence of synthetic aperture processing, in which set values of the dielectric constant are successively varied, and obtains the actual dielectric constant of the soil in which the targets are buried by evaluating the results of the synthetic aperture processing, whereby the need for special data collecting work only for obtaining the actual dielectric constant is eliminated.
    Type: Grant

  • System for detecting underground objects
    Patent number: 4831383
    Abstract: A system for detecting underground objects is disclosed wherein image data obtained through a deep range-migration correction and image data obtained through a shallow range-migration correction are combined so that data at the corresponding positions on both the image data at high level may mutually intensify, whereas other data may mutually weaken. The target spot on the thus combined image data is made sharp and provides sufficently high resolution.

  • Protective relay system for a power system
    Patent number: 4517619
    Abstract: A protective relay system for power system is disclosed which receives electrical information from several points of a power transmission line via optical fiber transmission line to protect the system from a line fault. Instruction is sent to the respective points when a line fault phenomenon is detected from the information received for separating it from the power system. The system has high immunity from electrical noise in the process of information transmission to obtain improved response.
