Abstract: Systems and methods are described for an audience derivation system to build user profiles based on user interactions with distributed media content, such as filters. The audience derivation system may be or include any instrumentality or aggregate of instrumentalities operable to compute, process, store, display, generate, communicate, or apply various forms of data for user profile building, audience derivation, control, or other purposes.

Abstract: An engagement tracking system monitors user interactions with media items to calculate an engagement score of the media item. The engagement tracking system may be or include a group of one or more server machines configured to detect an exposure of a client device to a media item maintained by the engagement tracking system. In response to detecting the exposure of the client device to the media item, the engagement tracking system tracks a location of the client device based on access requests to location based media items. The engagement tracking system may thereby monitor client devices exposed to the media item in order to calculate an engagement score of the media item.

Abstract: The generation of an electronic program grid guide is described. The electronic program grid guide (1200) represents various broadcast content providers, special content providers, and recommended media assets that are available from such providers. The media assets are recommended in view of user profile information where the listed media assets and content providers can change from time period to time period when displayed in the electronic program grid guide.

Abstract: Various aspects of methods and apparatuses are described herein. Some methods may include receiving video content, receiving metadata including a hierarchical order of metadata fields, and performing an enhancement operation on at least a portion of the video content according to settings associated with at least one of the metadata fields. The enhancement operation may include a video processing operation configured to modify one or more visual characteristics of the video content. The settings associated with the metadata field(s) may be predefined in a device that receives the video content and the metadata. The enhancement operation may be performed at a time based on a time code in the video content. The enhancement operation may be performed on a bounded area of an object. The hierarchical order may correspond to a type of display technology. The hierarchical order may correspond to information associated with a manufacturer of a display.

Abstract: A method for making a content recommendation to at least one user commences by first establishing a location for the at least one user. Thereafter a check occurs to determine which devices are available to the at least one user to use (e.g., consume) the content at the location. Next, the content available to the at least one user is determined based on at least the user's location and available devices available to the at least one user. A content recommendation is then made among the available content based on at least one attribute of the at least one user.

Abstract: The present disclosure is directed towards conducting a search for content and results using a user interface. A number of graphical objects (715) and filters are displayed where a search query is generated in response to a user gesture (730) that selects a graphical object and filter. The filters shown can change depending on various factors that impact what filters are selected from a group of filters (720).

Abstract: A method for caching an electronic program guide on a portable device commences by downloading channel information and program information to the portable from a local cache when the local cache contains relevant information. However, if the local cache lacks such information, the portable device downloads the channel information and program information from a server. The portable devices then builds a channel index and a program index from the downloaded channel information and program information, respectively to establish the electronic program guide on the portable device.

Abstract: An apparatus for separating fluorescent light from light elastically scattered/reflected from a material illuminated with a broadband illumination source includes a polarization discriminator, which separates the substantially polarized elastically scattered/reflected light from the unpolarized fluorescent light, and a spectrometer to analyze the full and separated reflectance spectra. A linear polarizer may be provided to polarize the illumination source. A method for separating fluorescence light induced in a material by broadband light from an elastic scattering/reflection component includes providing polarization discrimination to separate the components, the fluorescence light being substantially unpolarized, and spectrally analyzing the reflectance components. The method may include linearly polarizing the light source. A fluorescence spectra may be extracted from a minimum reflectance spectra or from a residual polarization reflectance spectra.

Abstract: A technique for forming an image of an object in or behind a scattering medium. In one embodiment, the object is made luminescent, and the luminescent light is selected for imaging while the illuminating light is filtered out. The quality of the image can be further improved by selected the portion of the luminescence spectrum that is strongly absorbed by the scattering medium.

Abstract: An apparatus for dissociation of gas molecules which absorb light comprising a resonance optical cavity, a nozzle for introducing gas molecules into the resonance optical cavity in contact with the high velocity gas molecules, a focusing lens for focusing the laser beam at the point of contact of the laser beam and the high velocity gas molecules, a 100 percent reflecting mirror for receiving the laser beam after it passes through such molecules, a partially reflecting mirror positioned between the molecules for reflecting a portion of laser beam back into the laser and the remainder of the beam through the gas molecules to the 100 percent reflecting mirror.

Abstract: Method and apparatus for isotope separation using the combination of selective pre-excitation by light radiation with further collisional processing in a DC, rf or microwave gas discharge field to recover ionized atoms or dissociated molecules of the selected isotope. Thus, uranium atoms or molecules in gas phase are irradiated in an interaction volume with light radiation of selected wavelength to raise energy states to a relatively stable second or mid-level. At the same time a gas discharge within said interaction volume subjects raised energy atoms or molecules to a collisional process tending to raise a significant number through the energy ladder to the respective ionization continuum or dissociation light whereupon the charged atoms or molecules may be collected as an enriched bulk of selected isotopic species.
