Abstract: A portable decolonization device can include a casing and an ultraviolet light source housed within the casing. The ultraviolet light source can be adapted to produce an emitted ultraviolet light. A filter can be oriented to filter the emitted ultraviolet light to produce a filtered ultraviolet light having a center wavelength and a narrowed bandwidth, wherein the narrowed bandwidth is from 150 nm to less than 230 nm. An aperture in the casing can be oriented to allow at least one of the filtered ultraviolet light and the emitted ultraviolet light to pass out of the casing.

Abstract: Techniques and systems for facilitating contextual information lookup and navigation are presented. Contextually relevant information can be presented without requiring a user to switch context or craft a search query. From within an application in which a user may consume or create content, a user may indicate text for further exploration. The application can receive the indication of an initial text selection, determine the intended selection and provide contextual search results to the user. In some implementations, the initial selection and a selection context (that includes at least some of the text surrounding the initial selection) is sent to a contextual search service which provides the intended selection and contextual search results based on the initial selection and selection context. In other implementations, text may be suggested by the contextual search service for selection from within the application.

Abstract: Techniques and systems are presented for providing “contextual insights,” or information that is tailored to the context of the content a user is consuming or authoring. Given a request for information about a topic, which may be indicated by a user gesture in an application, one or more queries to search services may be formulated without requiring entry of a search query directly by a user. Moreover, techniques and systems may leverage the context of the content the user is consuming or authoring, as well as user, device, and application metadata, to construct the queries and to organize and filter the results into relevant contextual insights.
