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

Abstract: Multilayer optical film reflective polarizers previously considered to have excessive off-axis color can provide adequate performance in an LC display in an “on-glass” configuration, laminated to a back absorbing polarizer of the display, without any light diffusing layer or air gap in such laminate. The reflective polarizer is a tentered-one-packet (TOP) multilayer film, having only one packet of microlayers, and oriented using a standard tenter such that birefringent microlayers in the film are biaxially birefringent. The thickness profile of optical repeat units (ORUs) in the microlayer packet is tailored to avoid excessive perceived color at normal and oblique angles. Color at high oblique angles in the white state of the display is reduced by positioning thicker ORUs closer to the absorbing polarizer, and by ensuring that, with regard to a boxcar average of the ORU thickness profile, the average slope from an ORU(600) to an ORU(645) does not exceed 1.8 times the average slope from an ORU(450) to the ORU(600).

Abstract: Method for active battery management to optimize battery performance. The method includes providing signal injections for charging and discharging of a battery. The signal injections include various charging and discharging profiles, rates, and endpoints. 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 charging and discharging of the battery is modified to optimize battery performance and to determine when to discharge the battery into a power grid in order to return power to the grid in exchange for an economic benefit such as a payment or rebate from a utility company.

Abstract: Multilayer optical film reflective polarizers previously considered to have excessive off-axis color can provide adequate performance in an LC display without any high haze light diffusing layer or air gap between the reflective polarizer and the back absorbing polarizer of the display. The reflective polarizer has only one packet of microlayers, and is oriented using a standard tenter such that birefringent microlayers in the film are biaxially birefringent. The microlayers in the packet have a layer thickness profile suitably tailored to avoid excessive perceived color at normal and oblique angles. A laminate made by combining this type of reflective polarizer with an absorbing polarizer, without an air gap or any high haze light diffusing layer or structure between the polarizers, can be used and incorporated into a liquid crystal display or the like with adequate color performance both at normal incidence and oblique incidence up to a polar angle of 60 degrees.

Abstract: An optical element includes an optical surface configured to receive light at a predetermined wavelength in a range from about 400 nm to about 1000 nm. The optical surface is defined by a vertical axis and a horizontal axis defining four Cartesian quadrants sequentially numbered in a counter-clockwise direction. A first longitudinal section of the optical surface is centered on the vertical axis and a second longitudinal section of the optical surface is centered on the horizontal axis. The first and second longitudinal section each extend across opposite edges of the optical surface and have a same substantially uniform retardance for substantially normally incident light. The optical element includes four discrete retarder sections. Each retarder section is disposed on a respective Cartesian quadrant of the optical surface and has a retardance difference from the substantially uniform retardance of the optical surface that is greater than zero.

Abstract: The present invention is directed towards methods and systems for characterizing sensors and developing classifiers for sensor responses on a utility grid. Experiments are conducted by selectively varying utility grid parameters and observing the responses of utility grid to the variation. Methods and systems of this invention then associate the particular responses of the utility grid sensors with specific variations in the grid parameters, based on knowledge of the areas of space and periods of time where the variation in grid parameters may affect the sensor response. This associated data is then used to updating a model of grid response.

Abstract: The present disclosure provides for an optical element useful in an optical device for illuminating the pupil of an eye, particularly for use with a head mountable display that can include eye-tracking. The optical device includes a light source and an optical element that transmits light, where light emitted from the light source is directed by the optical element toward the pupil of the eye, and attributes of the eye can then be detected by an optical sensor such as a camera. The light source can emit infrared light that is not visible to the human eye, so that world view images and/or combined digital images of the head-mountable display are not compromised.

Abstract: An optical stack including an oriented polymeric multilayer optical film and a non-birefringent optical filter is described. The oriented polymeric multilayer optical film has a first reflection band with a first band edge and the non-birefringent optical filter has a first blocking band. In some cases, the first blocking band contains the first band edge and the first blocking band provides a reduction in variation of a band edge of an overall blocking band of the optical stack.
