Abstract: An OLED display including a display panel and a color-correction component is described. A plurality of comparative display panels otherwise equivalent to the display panel but having one or more different optical thicknesses of OLED layers have a maximum white-point color shift from 0 to 45 degrees of WPCSC45 and a white-point axial efficiency of WPAEC. The plurality of comparative display panels defines a performance curve along a boundary of performance points. The OLED display and the display panel have respective maximum white-point color shifts from 0 to 45 degrees of WPCS45 and WPCS045 and respective white-point axial efficiencies of WPAE and WPAE0. WPCS045 and WPAE0 defines a performance point of the display panel to the right of the performance curve and WPCS45 and WPAE defines a performance point of the OLED display above or to the left of the performance curve. Methods of making the OLED display are described.

Abstract: A multilayer optical film includes a plurality of alternating polymeric first and second layers and optically absorptive material dispersed in at least one layer of the multilayer optical film. The multilayer optical film has an average optical transmittance in a visible wavelength range extending from about 450 nm to about 650 nm of about 0.5% to about 40%, an average optical reflectance in the visible wavelength range of less than about 40%, and an average optical reflectance in an infrared wavelength range extending from about 850 nm to about 1200 nm of greater than about 60%. For illuminant D65 light incident on the multilayer optical film, the multilayer optical film reflects and transmits portions of the incident light as reflected and transmitted lights that have color shifts below specified limits in a CIE L*a*b* color space. A glass laminate includes the multilayer optical film disposed between glass layers.

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: An example optical filter may include an angle blocking layer having a first angular light blocking range θAL relative to a normal axis, and an interference filter adjacent the angle blocking layer having a second angular light blocking range θIF relative to the normal axis. θIF and θAL at least partially overlap. The example optical filter has a predetermined light transmission zone comprising angles from 0° to a maximum light transmission angle θTmax relative to a normal axis of the major surface. The example optical filter has a predetermined angular light blocking zone θB, a union of θIF and θAL. An example optical filter may include an interference filter having an incidence angle-dependent reflection band and an absorbing layer having an absorption band. The incidence angle-dependent reflection band and the absorption band may overlap at at least one wavelength at at least one angle of incidence.

Abstract: An article including a reflector with a reflectance band that is substantially constant as a function of an incidence angle; a polymeric multilayer film packet including a front surface partial reflector with a reflectivity that increases with an increasing incidence angle away from the normal; and a wavelength-selective absorber with a transmission band that at least partially coincides with the reflectance band of the reflector.

Abstract: An optical film includes a plurality of polymeric layers. A plot of an average layer thickness versus a layer number of the polymeric layers includes a knee region separating a left region including at least N1 sequentially arranged polymeric layers where the polymeric layers have lower layer numbers from a middle region including at least N2 sequentially arranged polymeric layers where the polymeric layers have higher layer numbers. N1 is greater than about 50 and N2 is greater than about 10. A linear fit to the at least N1 sequentially arranged polymeric layers in the left region has a positive linear slope having a magnitude of greater than about 0.04 nm per layer number, and a linear fit to the at least N2 sequentially arranged polymeric layers in the middle region has a negative linear slope having a magnitude of greater than about 0.05 nm per layer number.

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: A display system including an imager for forming an image, and a projection lens system for projecting the image formed by the imager is described. For each pixel in the plurality of pixels, the imager is configured to emit a cone of light having a central ray having a direction that varies with location of the pixel in the imager. The variation may increase a brightness of an image projected through the projection lens system by at least 30 percent. The display system may include a light guide having a light insertion portion adapted to receive light; a light transport portion disposed to receive light from the light insertion portion; and a light extraction portion disposed to receive light from the light transport portion.

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.
