Title: Innovations of Paul L Donoho
Introduction
Paul L Donoho is a notable inventor based in Houston, TX (US). He has made significant contributions to the field of seismic data processing and recording. With a total of 3 patents, his work has advanced the methods used in underwater exploration and data compression.
Latest Patents
One of his latest patents is a method for reducing data storage and transmission requirements. This method applies wavelet transforms to digitized trace sequential data obtained from multiple acoustic sensors. The transforms are applied in at least three dimensions, and in the case of underwater exploration, four dimensions. The transformed data is ordered and quantized to increase the number of zero data values. The quantized data is then compressed using rim-length encoding and entropy coding. This allows for significant compression, often exceeding 100:1, without degrading the quality of the reconstructed data.
Another significant patent is the seafloor seismic recorder. This invention is designed to record acoustical and seismic signals at the ocean bottom with minimal noise. The device couples geophones to the water bottom, stores seismic data, and is retrievable. It consists of a chassis, a ballast ring, an electronics control package, a geophone package, a buoy means, and a leg extension means. This innovative design allows for effective data collection while minimizing interference.
