Abstract: A structured data processing system includes hardware processors and a memory in communication with the hardware processors. The memory stores a data structure and an execution environment. The data structure includes an electronic document. The execution environment includes a data extraction solver configured to perform operations including identifying a particular page of the electronic document; performing an optical character recognition (OCR) on the page to determine a plurality of alphanumeric text strings on the page; determining a type of the page; determining a layout of the page; determining at least one table on the page based at least in part on the determined type of the page and the determined layout of the page; and extracting a plurality of data from the determined table on the page.

Abstract: Techniques for extracting well log data include cropping one or more portions of a page of a well log file image that includes solid color space; further cropping portions of the page that includes well log file data from the cropped page of the well log file image; executing an optical character recognition (OCR) technique on the cropped portions of the page that includes well log file data to generate an OCR'd image of the cropped portions of the page that includes well log file data; parsing the well log file data from the OCR'd image; and comparing the parsed well log file data against one or more well log file data-specific rules to determine user-specified well log file data from the parsed well log file data.

Abstract: Placement of microphones and design of filters in a microphone network are solved simultaneously. Using filterbanks with multiple sub-channels for each microphone, the design of the filter response is solved simultaneously with placement. By using an objective function that penalizes the number of sub-channels in any solution, only some of many possible sub-channels and corresponding microphones and filters are selected while also solving for the filter responses for the selected sub-channels. For a given target location, the location of the microphones and the filter responses to beamform are optimized.

Abstract: Disclosed is a fuel additive system for internal combustion engines in which the fuel additive system is disposed on-board a vessel such as marine vessel or locomotive. The fuel additive system includes a fuel additive reservoir containing a fuel additive in fluid communication with an internal combustion engine. An electronically controlled injector, such as an eductor, is in fluid communication with the internal combustion engine and a fuel level meter or sensor, fuel efficiency meter or sensor, or other meter or sensor which, upon sensing certain pre-set conditions, e.g., increase of fuel level in a fuel storage tank or decrease in fuel efficiency, the injector injects an appropriate amount of fuel additive from the fuel additive reservoir and into the fuel stream that ultimately enters the internal combustion engine.
