Abstract: Various implementations disclosed herein include a method for aiding disinfection of a room. The method may include collecting, by one or more sensors in a disinfection system, activity data in the room. A computing device or output device may identify one or more hot spots from the activity data, in which the one or more hot spots indicate areas in the room for cleaning, and generate a contamination map containing the one or more hot spots. The output device may output the contamination map to an output device for viewing by a user.

Abstract: A technique allows a newsfeed item shown in a newsfeed of a social network to be easily promoted to another newsfeed in the social network. In a specific embodiment, the system receives a first user's promotion selection of an item displayed in a newsfeed of the first user. The item includes content provided by a second user. The first user is prompted to select a destination newsfeed. A selection of the destination newsfeed is received and the item is published on the destination newsfeed for a third user.

Abstract: Techniques are disclosed for obtaining a desired luminance and/or intensity distribution from any lighting fixture that is illuminated by a lightguide. The techniques can be used, for instance, to design a non-uniform surface texture (e.g., of light extraction features) for a lightguide, wherein the surface texture achieves a desired uniform or an intentionally non-uniform luminance distribution for a given lightguide shape/geometry, dimensions, and/or composition. In some embodiments, an iteration algorithm with illuminance distribution feedback is utilized to design a non-uniform surface texture (e.g., geometry, dimensions, quantity and/or spatial distribution of light extraction features) to achieve the target luminance distribution for a given lighting application.
