Abstract: Disclosed herein are devices and methods for assessing the surface of a target cardiac tissue and for delivering a tissue anchor to cardiac tissue at a preselected depth within the myocardium in a beating heart procedure. In one variation, an anchor delivery device comprises an elongate body, a tissue anchor disposed within a first longitudinal lumen of the elongate body, and a tissue depth indicator slidable within a second longitudinal lumen of the elongate body. The tissue depth indicator has a first configuration that indicates the boundary of the surface of the target tissue and a second configuration that indicates when the distal tip of the elongate body has been advanced to a preselected depth into the target tissue. In some variations, a tissue depth indicator may also be configured to resist or limit the penetration of the delivery device into tissue after a preselected depth has been reached.

Abstract: The disclosed embodiments include computerized methods, systems, and devices, including computer programs encoded on a computer storage medium, for generating terms of a search query based on a user's spoken utterances, identifying multiple cross-platform messages based on the generated terms, and to generating, via a presentation device, a single interface that enables the user to interact with identified messages. Based on a spoken utterance, the disclosed embodiments may determine user-specified search terms and/or criteria, and based on the user-specified search terms and/or criteria, may obtain cross-platform message data that corresponds to the search query. The communications device may generate one or more interface elements that describe corresponding ones of the cross-platform messages, which may be presented within a unified graphical user interface or voice-user interface by a communications device.

Abstract: A progressive bonus award system integrated within a mobile application is disclosed. Upon receiving data of a transaction performed by a player using the mobile application and determining that the player is participating in a progressive bonus award associated with the mobile application, a determination is made whether to issue a ticket to the player for the transaction performed by the player. The ticket includes a ticket identifier. An additional value is added to the progressive bonus award based at least in part on the transaction performed by the player to progressively increase the progressive bonus award during a promotional time period, and at the end of the promotional time period, a winning ticket identifier is randomly drawn and verified that the winning ticket identifier matches the ticket identifier of the ticket issued to the player and displayed within the mobile application along with an awarded amount to the player.

Abstract: In some implementations, the techniques described herein relate to a method including: collecting, by a processor, Wi-Fi sense data (WSD) associated with a client device in a network, wherein the WSD includes wireless characteristics indicative of one of a movement or position of the client device; generating, by the processor, a movement signature for the client device based on the WSD; classifying, by the processor, a fine-grained type of the client device utilizing the movement signature; and storing, by the processor, the fine-grained type in a storage device.

Abstract: In some implementations, the techniques described herein relate to a method including: classifying motion data and network device usage data in a networked environment; integrating the classified motion data and the network device usage data to create a combined dataset; processing the combined dataset to identify correlations between the motion data and the network device usage data; and using the identified correlations to predict an occupancy state of the environment.

Abstract: The present invention relates to a process for the hydroconversion of a feedstock including a plastic fraction (102), notably derived from plastic waste, and a heavy hydrocarbon fraction (101), notably a heavy hydrocarbon fraction containing a portion of at least 50% by weight, preferably at least 80% by weight, having a boiling temperature of at least 300° C. Hydroconversion involves one or more ebullated bed or hybrid ebullated-entrained bed reactors (20), and preferably two successive hydroconversion steps, in order to produce higher-quality, lower-boiling materials, for example for fuel production purposes, while at the same time allowing waste plastics to be upgraded.

Abstract: An electronic assembly includes a chassis having electronic module mounting positions, each having an electronic module received therein. A module recess is adjacent a first end of the electronic module and a module roller is adjacent a second end. A sealing retainer is coupled between the chassis and each electronic module, and includes a cooling gas passageway aligned with a chassis cooling gas passageway and a module cooling gas passageway. The sealing retainer includes a rigid retainer body having a retainer recess adjacent a first end to receive the module roller when the electronic module is in an inserted position. A retainer roller is received in a module recess and a compressible retainer body is between the rigid retainer body and the chassis.

Abstract: Various systems and methods are provided that display various geographic maps and depth graphs in an interactive user interface in substantially real-time in response to input from a user in order to determine information related to measured data points, depth levels, and geological layers and provide the determined information to the user in the interactive user interface. For example, a computing device may be configured to retrieve data from one or more databases and generate one or more interactive user interfaces. The one or more interactive user interfaces may display the retrieved data in a geographic map, a heat map, a cross-plot graph, or one or more depth graphs. The user interface may be interactive in that a user may manipulate any of the graphs to identify trends or current or future issues.

Abstract: The invention is a system for the in-situ monitoring of additive manufacturing. The system, without pre-calibration of a test sample, utilizes ultrasonic waves to conduct a layer-by-layer analysis of a three-dimensional component as it is being developed on a build plate. Resonant frequencies for each layer is measured and the difference between the resonant frequencies of consecutive layers are calculated to define a baseline frequency. Similarities or differences in baseline frequencies are used to validate the integrity of the layers of the component, and also to determine if structural inconsistencies exists. Based on these determinations, the system decides whether to continue printing or to halt printing.
