Abstract: An optical system for an augmented reality (AR) display comprises an image generator for generating image light, and an optical combiner for location in a field of view of a user of the optical system between the user and a scene. The optical combiner is configured to transmit ambient light from the scene towards an eye of the user, the ambient light being incident on a first side of the optical combiner. The image generator and the optical combiner are arranged so that the image light is incident on a second side of the optical combiner, the second side of the combiner being opposite to the first side of the optical combiner.

Abstract: The present disclosure concerns a method for stratifying the risk of a subject of having an advanced colorectal adenoma or a colorectal cancer based on determining the presence of overexpressed mRNA transcripts in the subject's stool. The method can be used to screen for subjects suitable for a colonoscopy. The method can also be used to tailor the stratified subject's treatment regimen.

Abstract: A work implement tilt control system for a tracked vehicle having a frame and a work implement mounted to the frame, the system comprising: a lifting unit configured to controllably raise or lower at least part of the work implement; an input device actionable by a first and second types of external actions associated with raising or lowering of the work implement; and a vehicle computer configured to send a signal to the lifting unit to carry out a lowering cycle of the work implement in case the vehicle computer determines that a set of conditions has been met. In some cases, the set of conditions includes: (i) a movement characteristic of the tracked vehicle exceeds a threshold; and (ii) the input device has been actioned by the first type of external action since carrying out the most recent lowering cycle of the work implement.

Abstract: Described herein are technologies relating to generating search results responsive to receipt of a query. More specifically, the query is mapped to a topic in response to receipt of a query, and social media accounts that have been labeled as being knowledgeable on the topic are identified.

Abstract: Holographic optical elements for augmented reality (AR) devices and methods of manufacturing and using the same are disclosed. An example AR device includes a holographic optical element (HOE) including a recorded optical function, and a projector to emit light toward the HOE. The HOE reflects the light based on the optical function to produce a full image corresponding to content perceivable by a user viewing the reflected light from within an eyebox. A first portion of the content is viewable from a first location within the eyebox. A second portion of the content is viewable from a second location within the eyebox. The first portion including different content than the second portion that is non-repeating between the first and second portions.

Abstract: Representative embodiments disclose mechanisms to compile documents into a timeline document that tracks the evolution of a topic over time. Social media documents can be used to identify importance or popularity of linked documents (i.e., documents shared by social media in a post, tweet, etc.). A collection of social media documents is analyzed and used to identify a series of n-grams and a ranked list of linked documents. A subset of the ranked list is selected based upon similarity to the series of n-grams. The subset is then summarized and captured, along with underlying supporting data, into an entry of a timeline document. Related entries in different timeline documents can be linked to create a pivot point that allows a user to jump from one timeline to another. Timeline documents can be made available as part of a search performed by a query system.

Abstract: Architecture that enables the identification of entities such as people and content in live broadcasts (e.g., streaming content (e.g., video) of live events) and non-live presentations (e.g., movies), in realtime, using recognition processes. This can be accomplished by extracting live data related to a live event. With respect to people entities, filtering can be performed to identify the named (people) entities from the extracted live data, and trending topics discovered as relate to the named entities, as associated with the live event. Multiple images of the named entities that capture the named entities under different conditions are captured for the named entities. The images are then processed to extract and learn facial features (train one or more models), and facial recognition is then performed on faces in the video using the trained model(s).

Abstract: Disclosed herein are devices and methods to provide a holographic optical element (HOE) having a modified shape and a structural attribute. At least one wavefront may be used to cause a first structure change in a material, used for the HOE, in a first shape. The material used for the HOE may be changed from the first shape to the modified shape to cause a second structure change in the material. The structural attribute in the material may be provided from a combination of the first structure change and the second structure change.

Abstract: Aspects of the technology described herein generate a comment-summary interface that can help a user find comments of interest to the user. The comment-summary interface allows a user to access comments according to topics instead of scrolling through all of the comments found in a comment section associated with a primary content, such as a news article on a website, a social post, product review, and such. Categorizing the comments into topics makes more efficient use of computer resources by avoiding the need to display comments that are not of interest to the user. The plurality of comments analyzed by aspects of the technology described herein are unstructured comments. Unstructured comments lack specific subject matter categories designated by a user or preselected by a webpage.
