Abstract: A fuel system including a fuel metering unit, a heat exchanger, a plurality of fuel nozzles, and a coke filtration system. The fuel metering unit is configured to meter a flow of a hydrocarbon fuel. The heat exchanger is fluidly connected to the fuel metering unit. The heat exchanger is configured to heat the hydrocarbon fuel to improve engine performance or efficiency. The plurality of fuel nozzles is fluidly connected to the heat exchanger downstream of the heat exchanger to receive the hydrocarbon fuel heated by the heat exchanger. The coke filtration system includes at least one filter to remove coke particles in the heated fuel. The coke filtration system is located upstream of the plurality of fuel nozzles and directly downstream of the heat exchanger.

Abstract: A method for generating synthetic images, each image simulating an image of an individual acquired by a vehicle interior camera, including: generating a plurality of models of individuals, each model including a three-dimensional representation of an individual's head; receiving a set of variable parameters and a probability distribution associated with each parameter; generating a set of configurations, each configuration corresponding to a combination of values or states taken by each parameter, such that the set of configurations is representative of the probability distribution of each parameter; generating, for each model of an individual, a set of images simulating images of the model of an individual acquired by a vehicle interior camera, where each image corresponds to a configuration generated for a variable parameter, and where each image further includes the three-dimensional positions of a set of points characterizing the individual's head; and storing all the images in a memory.
