| 20080267560 | Mode-field resizing in optical fibers - An all-fiber mode-field resizer comprises a first optical fiber configured to propagate signal light in a predetermined transverse mode along a longitudinal axis from a first input/output (I/O) port to a second I/O port. The first fiber is configured to have a first effective mode-field area and a first core V-parameter proximate the first I/O port and to have a second effective mode-field area and a second core V-parameter proximate the second I/O port. The second mode-field area is greater than the first mode-field area, and the second V-parameter is less than the first V-parameter. In one embodiment, the second V-parameter is less than approximately 1.3, and preferably less than 1.0. In another embodiment, the first V-parameter is greater than approximately 1.8. In yet another embodiment, our mode-field resizer is incorporated into a tapered fiber bundle. | 10-30-2008 |
| 20090016681 | Optical fiber configuration for dissipating stray light - An optical transmission fiber is formed to include a relatively low-index, relatively thin outer cladding layer disposed underneath the protective polymer outer coating. Stray light propagating along an inner cladding layer(s) within the fiber will be refracted into the thin outer cladding (by proper selection of refractive index values). The thin dimension of the outer cladding layer allows for the stray light to “leak” into the outer coating in a controlled, gradual manner so as to minimize heating of the coating associated with the presence of stray light. The inventive fiber may also be bent to assist in the movement of stray light into the coating. | 01-15-2009 |

| 20090290841 | Reduced Bend Sensitivity and Catastrophic Bend Loss In Single Mode Optical Fibers and Method of Making Same - An optical fiber that is relatively insensitive to bend loss and alleviates the problem of catastrophic bend loss comprises a core region and a cladding region configured to support and guide the propagation of light in a fundamental transverse mode. The cladding region includes (i) an outer cladding region, (ii) an annular pedestal (or ring) region, (iii) an annular inner trench region, and (iv) an annular outer trench region. The pedestal region and the outer cladding region each have a refractive index relatively close to that of the outer cladding region. In order to suppress HOMs the pedestal region is configured to resonantly couple at least one (unwanted) transverse mode of the core region (other than the fundamental mode) to at least one transverse mode of the pedestal region. In a preferred embodiment, the fiber is configured so that, at a signal wavelength of approximately 1550 nm, its bend loss is no more than about 0.1 dB/turn at bend radius of 5 mm and is no more than about 0.02 dB/turn at a bend radius of 10 mm. In addition, in one embodiment, the core region also includes an inner core region and an annular outer core (or shelf) region surrounding the inner core region. The outer core region extends radially a distance of less than 9 μm from the fiber axis. In another embodiment, the inner trench region includes an annular inner portion and an annular outer (or step) portion surrounding said inner portion. The refractive index of the step portion is greater than that of the inner portion. In a preferred embodiment, both of the foregoing features of the core region and the inner trench region are incorporated in the fiber. Also described are multi-tube fabrication techniques for making such fibers. | 11-26-2009 |

| 20110063415 | Hyperlinked 3D Video Inserts for Interactive Television - A viewer may directly interact with a 3D object that is virtually placed in a physical location in a video scene. Initially, the object appears as an integral part of the original video scene and does not interfere with the general viewer's experience of the program. A viewer may initiate interaction with the object using an input device. An interested viewer may navigate through the object's architecture based on the viewer's interest. For example, the viewer may drag the object to a new physical insertion point in the scene. The user may rotate the 3D object into different orientations and zoom in. Each orientation of the object, if selected by the viewer, may invoke a new linked object in the predefined architecture. For example, the viewer may walk through the linked objects in the predefined architecture or observe an object at an increasing level of detail. | 03-17-2011 |
| 20110141359 | In-Program Trigger of Video Content - Methods and systems for triggering an in-program display event are provided. In an embodiment, a method for triggering an in-program display event may include perfotining a video content analysis of a program display. The method may also include determining a display event trigger in real time based on the video content analysis. The method may further include displaying a display event in the program display based on the display event trigger. In some cases, the display event may be an interactive session. In another embodiment, a system for triggering an in-program display event may include a trigger mechanism and an insertion module. | 06-16-2011 |

| 20090013348 | SYSTEMS AND METHODS FOR EXPORTING DIGITAL CONTENT USING AN INTERACTIVE TELEVISION APPLICATION - The present invention relates to methods and systems for extracting digital content using an interactive television application. The interactive television application may allow the user to record programs on a set-top box. The interactive television application may also allow the user to extract the audio from one of the recorded programs and transfer the extracted audio to removable media (e.g., a CD-R). The interactive television application also be configured to perform a future transfer of digital content to removable media. The future transfer may occur without requiring any further user interaction. | 01-08-2009 |

| 20100050082 | Interactive Video Insertions, And Applications Thereof - Embodiments of this invention relate to controlling insertion of visual elements integrated into video. In an embodiment, a method enables control of insertions in a video. In the embodiment, control data is received from a user input device. Movement of at least one point of interest in a video is analyzed to determine video metadata. Finally, a visual element is inserted into a video according to the control data, and the visual element changes or moves with the video as specified by the video metadata to appear integrated with the video. | 02-25-2010 |
