Latest Patents

One of Berryman's latest patents is a "Method for distinguishing multiple targets using time-reversal acoustics." This method utilizes an iterative process to optimize signal detection for locating strongly reflecting targets in cluttered environments. An acoustic array sends a signal into a medium and receives the reflected signal, which is then time-reversed and sent back into the medium until the signal stabilizes. This process allows for the isolation of the largest eigenvalue/eigenvector combination, effectively determining the location of a single target. To locate additional targets, the method employs time-reversed signals, with half of them reversed in sign, allowing for further iterations to refine the detection process.

Another significant patent is "Discrimination of porosity and fluid saturation using seismic velocity analysis." This invention determines the state of saturation in subterranean formations using seismic velocity measurements. By analyzing shear and compressional wave velocity data, the method provides accurate partial saturation data. It distinguishes regions of the formation with similar solid material properties and porosity, enhancing the understanding of subsurface conditions.
