摘要： Disclosed are methods and apparatus for processing linguistic expressions (e.g., opinionated text documents). The linguistic expressions are processed by, firstly, detecting topics of interest discussed in the linguistic expressions. The sentiment, or sentiments, of an originator with respect to each of the topics detected in the linguistic expressions is then assessed. The originators are then grouped (or clustered) into one or more groups based on the similarities between the originators' respective sets of detected topics and corresponding sentiments. Semantic information is then associated with a given group. Finally, for a given member of a given group, a profile is created or updated. This profile comprises attributes that may be based on a degree of membership of the given member to the given group and the semantic information associated with the given group.

摘要： This invention discloses a multi-pitching angle suspended space 3D display device with 360° FOV, comprising: a transmitted composite deflective diffusing screen, a high speed projector, an image generator, a detecting module and a rotating drive mechanism. The high speed projector projects the composite images of the 3D objects of different pitching angles and horizontal 360° views to the composite deflective diffusing screen that rotates at a high speed. The composite deflective diffusing screen is able to control the vertical deflecting and scattering angles and horizontal diffusing angle for incident rays with different angles, allowing the surrounding viewers at different height levels to see the images corresponding to their viewpoints, making the displayed 3D objects suspended over the composite deflecting scattering screen, of which the position does not change as the height of the viewpoint changes. The multi-pitching angle suspended space 3D display device with 360° FOV allows watching by multiple persons at multiple pitching angles and horizontal 360° FOV in naked eyes, realizing space occlusion, exploration and interaction.

摘要： This invention discloses a combined-screen-based multi-pitching angle suspended panoramic space 3D display device comprising: a combined deflective diffusing screen, a high speed projector, an image control module, a rotation detecting module, a motor and a drive mechanism. The high speed projector projects the composite images of the 3D objects of different pitching angles and horizontal 360° FOV to different areas of the combined deflective diffusing screen. Each area of the combined deflective diffusing screen controls the deflecting angle and the scattering angle in the vertical direction and the diffusing angle in the horizontal direction, ensuring that the eyes of the surrounding viewers of different height levels can see the 3D images corresponding to their respective positions, representing the 3D scene suspended over the combined deflective diffusing screen. The multi-pitching angle suspended panoramic space 3D display device provided in this invention allows watching by multiple persons at multiple pitching angles and horizontal 360° FOV in naked eyes, realizing space occlusion, allows exploration and interaction.

摘要： Channel power management may be achieved in a branched optical communication system such that uniform loading is provided across branch channels on a branch drop path without passing information signals that are not intended for the branch terminal to the branch drop path. In general, a system and method consistent with the present disclosure reuses one or more loading signals (e.g., noise bands) from the branch add path to maintain uniform loading in the branch drop path of the same branch. The system and method thus prevents trunk channels from being dropped to a branch terminal when those trunk channels are not intended for the branch terminal.
