Latest Patents
D Mark Fejfar holds a patent for an "Enhanced vehicle fuel quantity indication system." This system includes a fuel quantity indicator system (FQIS) designed for aircraft and other vehicles. The FQIS features memory/data storage and a fuel quantity processing unit (FQPU). A neural network, trained through machine learning and operating on the FQPU, receives inputs from fuel tank sensors. These inputs include tank density, fuel volume, and water presence within the tank at specific measurement times. Additionally, the neural network processes fuel flow inputs from flow sensors, which indicate fuel flow to engines and auxiliary power units (APU). Based on these inputs, the neural network calculates an estimated fuel quantity (EFQ) remaining across all fuel tanks at or near a particular measurement time. D Mark Fejfar's innovative patent enhances the accuracy and reliability of fuel quantity measurements in vehicles.
