Abstract: A tissue lumen stent is provided with a body having an elongated tubular configuration and a foreshortened configuration. In the foreshortened configuration, downstream and upstream ends of the body expand radially into downstream and upstream flange structures, leaving a generally cylindrical saddle region therebetween. In some embodiments, the flange structures are non-symmetrical with respect to one another. Systems and methods of using the stents are also disclosed.

Abstract: Embodiments presented herein describe techniques for generating a linguistic model of input data obtained from a data source (e.g., a video camera). According to one embodiment of the present disclosure, a sequence of symbols is generated based on an ordered stream of normalized vectors generated from the input data. A dictionary of words is generated from combinations of the ordered sequence of symbols based on a frequency at which combinations of symbols appear in the ordered sequence of symbols. A plurality of phrases is generated based an ordered sequence of words from the dictionary observed in the ordered sequence of symbols based on a frequency by which combinations of words in ordered sequence of words appear relative to one another.

Abstract: Embodiments presented herein describe a method for processing streams of data of one or more networked computer systems. According to one embodiment of the present disclosure, an ordered stream of normalized vectors corresponding to information security data obtained from one or more sensors monitoring a computer network is received. A neuro-linguistic model of the information security data is generated by clustering the ordered stream of vectors and assigning a letter to each cluster, outputting an ordered sequence of letters based on a mapping of the ordered stream of normalized vectors to the clusters, building a dictionary of words from of the ordered output of letters, outputting an ordered stream of words based on the ordered output of letters, and generating a plurality of phrases based on the ordered output of words.

Abstract: A method for proactive notifications in a voice interface device includes: receiving a first user voice request for an action with an future performance time; assigning the first user voice request to a voice assistant service for performance; subsequent to the receiving, receiving a second user voice request and in response to the second user voice request initiating a conversation with the user; and during the conversation: receiving a notification from the voice assistant service of performance of the action; triggering a first audible announcement to the user to indicate a transition from the conversation and interrupting the conversation; triggering a second audible announcement to the user to indicate performance of the action; and triggering a third audible announcement to the user to indicate a transition back to the conversation and rejoining the conversation.

Abstract: A clamp assembly to secure a yoke to a valve body of a knife gate valve is provided. The clamp assembly can include a bolt that is configured to extend through a first bushing, a first spring member, a first side wall of the yoke, the valve body, a second side wall of the yoke, a second spring member, and a second bushing. The clamp assembly can be configured to pin the yoke to the valve body, apply a pressure-containing preload to the valve body via the first and second bushings, and compress the first spring member between the first bushing and the first side wall of the yoke and the second spring member between the second bushing and the second side wall of the yoke.

Abstract: Embodiments of the invention provide a knife gate valve for flow along a flow path. The knife gate valve can include a body structure that includes a gate passage, a gate disposed to move within the gate passage between open and closed positions to selectively open or close a fluid aperture, and a gate seat configured to engage a free end and lateral edges of the gate. A transverse element can be formed from resilient material and can extend laterally across the gate passage to form a seal with a first side of the gate and with the gate seat.

Abstract: Embodiments provide a gate valve including a first body half that defines a first process fluid aperture, a first chest portion, and a first chest gate support recess formed in the first chest portion. A second body half defines a second process fluid aperture that is aligned with the first process fluid aperture, a second chest portion, and a second chest gate support recess that is formed in the second chest portion. A gate is movable relative to the first body half and the second body half. A first chest gate support is received within the first chest gate support recess, and a second chest gate support is received within the second chest gate support recess.

Abstract: Embodiments provide a gate valve including a first body half that defines a first process fluid aperture, a second body half that defines a second process fluid aperture aligned with the first process fluid aperture, a gate that is movable relative to the first body half and the second body, and a first port gate support that is arranged on the first body half and extends into the first process fluid aperture. The first port gate support defines a curved surface that is configured to be in contact with a process fluid.
