摘要： A method of optimizing a plurality of control signals used in operating a vehicle is described. The operation has a plurality of associated measurable parameters. The method includes: for each control signal, selecting a plurality of potential optimum values from a predetermined set; operating the vehicle in at least a first sequence of operation iterations, where for each pair of sequential first and second operation iterations in the first sequence of operation iterations, the potential optimum value of one control signal in the first operation iteration is replaced in the second operation iteration with a next potential optimum value of the control signal, while the potential optimum values of the remaining control signals are maintained; for each operation iteration, measuring each parameter in the plurality of measurable parameters; and generating confidence intervals for the control signals to determine causal relationships between the control signals and the measurable parameters.

摘要： Example systems may include one or both of a light emitter and a light receiver, and an optical filter. The optical filter may include a wavelength selective scattering layer configured to scatter visible light. The optical filter may include a wavelength selective reflecting layer having a predetermined transmission band configured to compensate for a color deviation. The optical filter may include a broadband reflecting layer having a predetermined reflection band configured to compensate for a color deviation. The optical filter may include a low-index layer configured to reduce a color deviation in light emitted by the light emitter or received by the light receiver. The wavelength selective scattering layer may include nanoparticles dispersed in a binder, wherein the ratio of the nanoparticles to the binder by weight is at least 50%.
