  • Patent number: 11419667
    Abstract: Surgical instruments and system and methods for using surgical instruments are disclosed. A surgical instrument comprises an end effector comprising an ultrasonic blade and clamp arm, an ultrasonic transducer, and a control circuit. The ultrasonic transducer ultrasonically oscillates the ultrasonic blade in response to a drive signal from a generator. The end effector receives electrosurgical energy to weld tissue. The control circuit determines a resonant frequency measure indicative of a thermally induced change in resonant frequency and a electrical continuity measure; calculates a weld focal point based on the determined measures, controls closure of the clamp arm to vary a pressure applied by the clamp arm to provide a threshold control pressure to the tissue loaded into the end effector, and maintains a gap between the ultrasonic blade and clamp arm at a point proximal to the proximal end of the tissue. Pressure is varied based on corresponding weld focal point.

  • Publication number: 20220252876
    Abstract: A high-assurance headtracking system for a head worn display (HWD) incorporating ground-truth fiducials is disclosed. In embodiments, the headtracking system includes a camera fixed to a mobile platform (e.g., an aircraft cockpit) and oriented toward a pilot wearing the HWD. Images captured by the camera detect fiducial markers attached to the HWD (and fixed in a device reference frame) and static fiducial markers fixed to the mobile platform, each static fiducial marker including a constellation of individual markers having a known position and orientation in the platform reference frame. The headtracking system include control processors for analyzing the images and identifying therein the device-frame and static fiducial markers. The headtracking system determines a device pose of the HWD relative to the platform reference frame and monitors the device pose for drift or error based on the known positions of the identified static fiducial markers.

  • Publication number: 20200059684
    Abstract: A method includes identifying, by a server, a content location assigned to a first content slot of a schedule template defining a display rotation loop based on multiple content slots. Each of the content slots in the schedule is associated with slot criteria, and the schedule template is associated with a digital display. The server generates schedule data that indicates the display rotation loop, the content location, and the slot criteria. Dynamic content retrievable from the content location is displayable at the digital display at a first time. The first time is based on the first slot criteria of the first content slot. The server transmits the schedule data via a network to the digital display.

  • Patent number: 10491933
    Abstract: A method includes generating, by a server, an inventory corresponding to a plurality of time slots. The method also includes receiving data corresponding to a plurality of inventory bookings associated with the inventory. A subset of time slots that are assigned to a digital display of a plurality of networked digital displays may be identified by the server based on the data corresponding to the plurality of bookings. Media content that is assigned to each slot of the subset of time slots is identified by the server. The method may further include generating, based on slot criteria corresponding to the subset of time slots, a schedule template that defines a rotation loop. The media content is displayable on the digital display at times defined by the display rotation loop. The schedule template is transmitted to the digital display via a network.

  • Patent number: 10083398
    Abstract: An approach is provided in which a knowledge manager generates term tokens from terms included in an original text stream, and generates annotation tokens with corresponding term location information. In turn, the knowledge manager generates a knowledge structure that indexes the term tokens into original text fields and indexes the annotation tokens into parallel fields that align to the original text fields based upon the term location information.

  • Patent number: 9904674
    Abstract: An approach is provided in which a knowledge manager generates syntactic annotation tokens that correspond to syntactic relationships between terms included in a source document. The knowledge manager creates a knowledge structure that stores the syntactic annotation tokens in parallel fields and stores the source document terms in original text fields, which align to the parallel fields. In turn, the knowledge manager utilizes the knowledge structure to generate answers to questions based upon the syntactic annotation tokens.

  • Patent number: 9792280
    Abstract: Mechanisms are provided for performing context based synonym filtering for natural language processing. Content is parsed into one or more conceptual units, wherein each conceptual unit comprises a portion of text of the content that is associated with a single concept. For each conceptual unit, a term in the conceptual unit is identified that has a synonym to be utilized during natural language processing of the content. A first measure of relatedness of the term to at least one other term in the conceptual unit is determined. A second measure of relatedness of the synonym of the term to the at least one other term in the conceptual unit is determined. A determination whether or not to utilize the synonym when performing natural language processing on the conceptual unit is made based on the first and second measures of relatedness and natural language processing on the content is performed accordingly.

  • Patent number: 9734238
    Abstract: According to an aspect, a question answering computer system determines a set of search terms for a given question. A plurality of passages that each includes at least one search term in the set of search terms is identified in response to a search of a document for search terms in the set of search terms. A passage from the plurality of passages is selected. A context based score of the selected passage that indicates the likelihood that the selected passage contains an answer to the question is generated based on criteria that specify a relationship among the set of search terms, content of the passage, and content of at least one other passage in the plurality of passages.

  • Patent number: 9727637
    Abstract: A mechanism is provided for retrieving candidate answers from a corpus of documents. The mechanism receives an input question for which an answer is sought. The mechanism extracts features of the input question based on a natural language processing. The mechanism executes a first search of the corpus of documents based on a first subset of the extracted features of the input question and an initial evaluation of a utility of the first subset of extracted features to generate a subset of documents. The mechanism executes a second search of a set of passages extracted from the subset of documents based on a second subset of the extracted features of the input question and a reevaluation of the utility of the second subset of extracted features thereby forming a subset of passages. The mechanism generates query results from the subset of passages matching from which candidate answers are identified.

  • Patent number: 9558264
    Abstract: Mechanisms are provided for identifying commonalities between candidate answers generated by a Question and Answer (QA) system in response to an input question. The mechanisms receive a plurality of candidate answers for an input question from the QA system and identify terms present in the candidate answers. The mechanisms determine relationships between terms in each of the candidate answers and determine a common relationship between a first term and a second term, the common relationship being common amongst at least a subset of the plurality of candidate answers, based on the determined relationships between terms in each of the candidate answers. The mechanisms present the plurality of candidate answers and the common relationship to a user.
