Abstract: Anchoring systems for disposition in wellbores and tubular devices comprise a tubular member defined by two or more radially expandable slip members. The upper ends of the slip members are shaped such that when the slip members are in their respective run-in positions and in their respective set positions, a portion of an upper end of one slip member overlaps a portion of an upper end of another slip member so that the longitudinal space between each slip member that is created when the slip members are in their set position are blocked by the upper end of at least one of the slip members. Thus, in their set position, the upper end of at least one of the slip members provides a back-up to a sealing element that can be disposed adjacent to and in contact with the upper ends of the slip members when in their set positions.

Abstract: Various embodiments provide techniques for calibrating and annotating video content. In one or more embodiments, an instance of video content can be calibrated with one or more geographical models and/or existing calibrated video content to correlate the instance of video content with one or more geographical locations.

A user may also access annotations provided by other users that may be relevant to a particular instance of video content.

Abstract: A user behavior model provides personalized recommendations based in part on time and location, particularly to users of mobile devices. Entity types are ranked according to relevance to the user. Example entity types are restaurant, hotel, etc. The relevance may be based on reference to a large-scale database containing queries from other users. Additionally, entities within each entity type may be ranked based on relevance to the user and the time and location context. A user interface may display a ranked list of entity types, such as restaurant, hotel, etc., wherein each entity type is represented by a highest-ranked entity with the entity type. Thus, the user interface may display a highest-ranked restaurant, a highest-ranked hotel, etc. Upon user selection of one such entity type the user interface is replaced with a second user interface, for example showing a ranked hierarchy of restaurants, headed by the highest-ranked restaurant.

Abstract: Apparatuses for restricting fluid flow through a well conduit comprise a tubular member having an inner wall surface defining a bore and a seat in sliding engagement with the inner wall surface. Operatively associated with the seat is a plug element support member having an expanded position when the apparatus is in a run-in position and a contracted position when the apparatus is in a set position. A plug element adapted to be disposed into the bore and landed on the seat to restrict fluid flow through the bore and the well conduit is used to move the seat which in turn moves the plug element support member from the expanded position to the contracted position, thereby providing support to the plug member landed on the seat.

Abstract: A user may perform an image search on an object shown in an image. The user may use a mobile device to display an image. In response to displaying the image, the client device may send the image to a visual search system for image segmentation. Upon receiving a segmented image from the visual search system, the client device may display the segmented image to the user who may select one or more segments including an object of interest to instantiate a search. The visual search system may formulate a search query based on the one or more selected segments and perform a search using the search query. The visual search system may then return search results to the client device for display to the user.

Abstract: A downhole tool for removing debris from a wellbore comprises a body having a bore, a collection member, and a means for creating a hydraulic barrier within a wellbore annulus. The hydraulic barrier within the wellbore annulus restricts upward movement of a debris laden fluid within the wellbore annulus causing the debris laden fluid to be directed toward the collection member. Thus, the hydraulic barrier facilitates removal of debris from the wellbore.

Abstract: A downhole tool for removing debris from a wellbore comprises a screen member, an incoming fluid accelerator, and a cavity for capturing debris. The incoming fluid accelerator is disposed above the screen and accelerates the flow of an incoming fluid through the accelerator and into a screen bore. The incoming fluid then exits the bottom of the tool, mixes with wellbore fluid containing debris to form a combination fluid that is transported upward within the wellbore annulus. A pressure differential between the incoming fluid flowing within the screen bore and the wellbore annulus pulls the combination fluid containing the debris into the cavity where the debris is captured. Fluid and/or debris not blocked by the screen flows through the screen into the screen bore to be circulated downward and out of the tool where it can pick up additional debris for capture.

Abstract: A downhole tool for moving fluid through the tool comprises a rotatable sleeve disposed within a bore of the tool. The sleeve includes an opened upper end and a closed lower end to define a cavity. A fluid movement profile is disposed along the lower end. A directional port is disposed in the side of the sleeve in fluid communication with the cavity and an upper port disposed in the tool. The upper port can be isolated from a lower port in the tool, the lower port being in fluid communication with the fluid movement profile. A first fluid flowing downward enters the cavity, exits the directional port causing rotation of the sleeve, and flows out the tool through the upper port. Sleeve rotation causes a second fluid to be drawn upward into contact with the fluid movement profile which directs the second fluid out of the lower port.

Abstract: Downhole cutting tools comprise a mandrel, a housing, a sleeve and a cutting blade. The mandrel comprises an inner wall surface defining a bore, and an outer wall surface. The housing is secured to the outer wall surface of the mandrel and comprises an opening. The sleeve is engaged with the outer wall surface of the mandrel. The sleeve comprises a profile that is operatively associated with a profile of the cutting blade such that movement of the sleeve causes the profile of the piston to slide along the profile of the cutting blade. In so doing, the cutting blade is radially extended outward through the opening in the housing to abrade an object located outside the housing. Movement of the sleeve can be achieved by pumping fluid down a bore in the mandrel to slide the sleeve long the outer wall surface of the mandrel.

Abstract: A face cartooning system is described. In one implementation, the system generates an attractive cartoon face or graphic of a user's facial image. The system extracts facial features separately and applies pixel-based techniques customized to each facial feature. The style of cartoon face achieved resembles the likeness of the user more than cartoons generated by conventional vector-based cartooning techniques. The cartoon faces thus achieved provide an attractive facial appearance and thus have wide applicability in art, gaming, and messaging applications in which a pleasing degree of realism is desirable without exaggerated comedy or caricature.

Abstract: A non-linear beam tracing technique that supports full non-linear beam tracing effects including multiple reflections and refractions for computer graphics applications. The technique introduces non-linear beam tracing to render non-linear ray tracing effects such as curved mirror reflection, refraction, caustics, and shadows. Beams are allowed to be non-linear where rays within the same beam are not parallel or do not intersect at a single point. Such is the case when a primary beam bounces off of a surface and spawns one or more secondary rays or beams. Secondary beams can be rendered in a similar manner to primary rays or beams via polygon streaming. Beyond smooth ray bundles, the technique can also be applied to incoherent ray bundles which is useful for rendering bump mapped surfaces.
