  • Patent number: 4363113
    Abstract: A method of seismic exploration by which substantially plane or substantially cylindrical seismic energy waves are simulated by combining reflectional signal traces of conventional spherical seismic waves. Seismic sources and receivers are established in sets at positions such that at least one of the sets includes a plurality of positions spaced over an extent of the area being explored having either one or two dimensions which are large relative to a seismic energy wavelength. Seismic energy is imparted into the earth from the sources and signals are generated in response to seismic energy received at the receivers. The generated signals are then combined into a form simulating the reflection response of the earth to seismic energy having a substantially continuous wavefront in either one dimension, simulating a cylindrical seismic energy wave, or two dimensions, simulating a plane seismic wave.

  • Patent number: 3995312
    Abstract: A color dot display and method of forming same by applying colors to dot areas within a matrix of cells in accordance with a color code defining the number of dot areas in the cells, and their locations in the cells, to receive the colors. The proportion of dots of a particular color in a cell defines the representation or saturation of that color in the cell, while the superposition, whether visual or physical or both, of the dots of the various component colors in a cell defines the apparent or resulting color of the cell.
