Abstract: Optical constructions use a low index of refraction layer disposed between a low absorption layer and a high absorption layer to increase confinement of light to the low absorption region of the optical constructions. Low index layers can be used in optical constructions that have multi-tiered light confinement. In these constructions, a first tier of reflection is provided when light is reflected at the surface of a low index optical film which is disposed directly or indirectly on a light guide. A second tier of reflection occurs at the surface of a light redirecting film having appropriately oriented refractive structures.

Abstract: A display device is provided that includes a photovoltaic cell, a dichroic reflector adjacent to the photovoltaic cell, and a low refractive index layer adjacent to the dichroic reflector. The low refractive index layer can have an index of refraction of from about 1.1 to about 1.4.

Abstract: Systems and methods for automatically tagging a media asset are provided. Verbal input is received from a user while the user is accessing the media asset. A request to adjust playback of the media asset is received from the user. Responsive to receiving the verbal input and the request, a combination of the verbal input and the request is cross-referenced with an attribute database to identify an attribute associated with the combination. The identified attribute is associated with the media asset.

Abstract: Methods and systems described herein provide for visualizing content across different time segments of a media asset. Information about content within a particular time segment of a media asset is retrieved. This content information is generated by processing user-generated messages corresponding to the particular time segment. Content descriptors are generated based on the received content information corresponding to the particular time segment. A timeline is generated, independently of presenting a media asset, wherein the timeline visually associates content descriptors with their corresponding time segments of the media asset. When these content descriptors are selected by a user, the user-generated messages corresponding to the content descriptor at the corresponding time segment are displayed to the user.

Abstract: This application describes a front-lit reflective display assembly including a reflective display and an illumination article for front-lighting the display when the article is optically coupled to a light source. The illumination article includes a variable index light extraction layer optically coupled to a lightguide. The variable index light extraction layer has first and second regions, the first region comprising nanovoided polymeric material, the second region comprising the nanovoided polymeric material and an additional material, the first and second regions being disposed such that for light being transported at a supercritical angle in the lightguide, the variable index light extraction layer selectively extracts the light in a predetermined way based on the geometric arrangement of the first and second regions. Front-lit reflective display devices including the front-lit reflective display assembly optically coupled to a light source are also described.

Abstract: Methods and systems are disclosed herein for a media guidance application that predicts user preferences based on detected events. For example, in response to a trigger, the media guidance application may monitor data associated with a user. The media guidance application may then process the monitored data to determine if the monitored data indicates that a user profile of a user should be updated.

Abstract: Methods and systems are disclosed herein for providing ancillary content in media assets. Specifically, a media guidance application may alert a user to remove, or modify, portions of a media asset based on an emotional response profile associated with the media asset. The emotional response profile may indicate representative emotional responses of other users associated with one or more progression points of the media asset. Upon determining that a user currently consuming the media asset is approaching a portion of the media asset associated with undesirable emotional responses, the media guidance application may alert the user to remove, or modify, the undesirable portion.

Abstract: A film construction (610) includes a group of microlayers that reflect normally incident light polarized along a first axis more than normally incident light polarized along a second axis. The microlayers are arranged into optical repeat units (ORUs) that have a layer thickness distribution along a thickness axis perpendicular to the first and second axes that provides the group of microlayers with an intermediate reflectivity over an extended reflection band for a given incidence condition. The ORUs include thinner ORUs whose thicknesses are less than an average thickness, and thicker ORUs whose thicknesses are greater than the average thickness. The group of microlayers is optically immersed in a medium having a refractive index greater than air, such that “supercritical light” can propagate through the microlayers. The microlayers are oriented such that, on average, the thinner ORUs are closer than the thicker ORUs to an output surface of the construction.
