A computer, including a processor and a memory, the memory including instructions to be executed by the processor to calibrate utility functions that determine optimal vehicle actions based on an approximate Nash equilibrium solution for multiple agents by determining a difference between model-predicted future states for the multiple agents to observed states for the multiple agents. The instructions can include further instructions to determine a vehicle path for a vehicle based on the optimal vehicle actions.

Vehicle path planning

A computer, including a processor and a memory, the memory including instructions to be executed by the processor to determine optimal vehicle actions based on a modified version of a Nash equilibrium solution to a multiple agent game, wherein the Nash equilibrium solution is modified by performing an adaptive grid search optimization technique based on calculating rewards and penalties for the agents to determine optimal vehicle actions, wherein the agents include one or more of autonomous vehicles, non-autonomous vehicles, stationary objects, and non-stationary objects including pedestrians and wherein the rewards and the penalties for the agents are determined by simulating behavior of the agents to determine possible future states for the agents to determine the optimal vehicle actions. The instructions can include further instructions to determine a vehicle path based on the optimal vehicle actions and download the vehicle path to the vehicle.

A method for modulating the intensity of an x-ray beam in an x-ray inspection system so as to maintain the highest penetration power and optimum image quality subject to keeping the ambient radiation generated by the x-rays below a specified standard.

X-ray ambient level safety system

An X-ray imaging system which measures X-rays scattered by material concealed within an enveloping surface. A beam of X-ray radiation is incident on the enveloping surface and scattered onto one or more arrays of detectors. One or more masks of material opaque to X-ray transmission but for a series of apertures is interposed between the object and the detectors so as to cast shadows on different parts of the detector array. The image of the scattering material, as detected at the detector array, is modulated by the pattern of mask apertures. A controller reconstructs the image of the illuminated line. By scanning the illumination with respect to the object, an image of the entire object in scattered radiation is obtained, while use of multiple arrays or variation of geometrical settings allows reconstruction of the source of scattering in three dimensions.
