Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining causal models for controlling environments. One of the methods includes repeatedly selecting, by a control system for the environment, control settings for the environment based on internal parameters of the control system, wherein: at least some of the control settings for the environment are selected based on a causal model, and the internal parameters include a first set of internal parameters that define a number of previously received performance metric values that are used to generate the causal model for a particular controllable element; obtaining, for each selected control setting, a performance metric value; determining that generating the causal model for the at particular controllable element would result in higher system performance; and adjusting, based on the determining, the first set of internal parameters.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining causal models for controlling environments. One of the methods includes identifying a procedural instance; determining a temporal extent for the procedural instance based on temporal extent parameters for the one or more entities in the procedural instance; selecting control settings for the procedural instance; monitoring environment responses to the control settings that are received for the one or more entities; determining which of the environment responses to attribute to the procedural instance in a causal model; and adjusting, based at least in part on the environment responses that are attributed to the procedural instance, the temporal extent parameters for the one or more entities.

Abstract: A light control film comprising a light input surface and a light output surface opposite the light input surface; alternating transmissive regions and absorptive regions disposed between the light input surface and the light output surface, wherein each absorptive region has an aspect ratio of at least 30, and wherein each transmissive region has a first refractive index; and a plurality of low index layers, wherein each low index layer is disposed between each transmissive region and an adjacent absorptive region, and wherein each low index layer has a second refractive index less than the first refractive index of each transmissive region.

Abstract: A method is provided that comprises determining a first time period during which a first product is available in an inventory at a point of purchase according to a model that uses (a) sales data, (b) inventory data, or (c) both sales data and inventory data. The inventory data comprises data from an inventory management system, sampled during the first time period, as an input. The method further comprises determining a second time period during which the first product is unavailable in the inventory according to the model and comparing a first time period sales data to a second time period sales data to determine a product unavailability effect. The method also comprises using the product unavailability effect to change an assortment at the point of purchase.

Abstract: Method for predictive control of a system having subsystems. The method includes providing signal injections relating to performance of the system. The signal injections include various operational controls for the system or its subsystems. Response signals corresponding with the signal injections are received, and a utility of those signals is measured. Based upon the utility of the response signals, data relating to operational controls is modified to optimize performance of the system via its subsystems.

Abstract: Light control films comprise a light input surface and alight output surface opposite the light input surface and alternating transmissive regions and absorptive regions disposed between the light input surface and the light output surface. The absorptive regions have an aspect ratio of at least 30 and are canted in the same direction. The alternating transmissive regions and absorbing regions have a maximum relative transmission at a viewing angle other than 0 degrees.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for optimizing operations of a supply chain. In one aspect, the method comprises repeatedly performing the following: i) selecting a configuration of input settings for operating a supply chain, based on a causal model that measures causal relationships between input settings and a measure of success of the supply chain; ii) determining the measure of success of the supply chain operated using the configuration of input settings; and iii) adjusting, based on the measure of success of the supply chain operated using the configuration of input settings, the causal model.

Abstract: The disclosure describes asymmetric turning films (ATFs) that may be used in conjunction with multiple light sources in a liquid crystal display assembly to provide multiple different characteristic output distributions of light. In some examples, the ATFs include a structured surface defining a plurality of microstructures having two or more faces with each face configured to reflect light in different directions. The microstructure may define a microstructure axis and an angle gradient characterizing the rotation of the microstructure axis across the structured surface of the ATF.
