  • Publication number: 20210295357
    Abstract: Machine logic for causing a computer system to perform the following operations (not necessarily in the following order): (i) receiving, by a historical decisions and opinions data store, decisions and opinions that have been communicated, propagated and/or otherwise espoused by a first entity; (ii) receiving, by an influencer data store, a plurality of influencer data sets, with each influencer data set including information indicative of opinions expressed by a respectively corresponding influencer; (iii) performing, by reverse chain engine, reverse chaining using the following inputs: (a) data of the historical decisions and opinions data store, and (b) the plurality of influencer data sets; and (iv) predicting, by a prediction engine, a likely future decision of the first entity using output of the reverse chaining operation.

  • Patent number: 11106030
    Abstract: An optical distance measuring system includes a first transmitter, a first solid state device, and a receiver. The first transmitter is configured to generate a first optical waveform. The first solid state device is configured to receive the first optical waveform and steer the first optical waveform toward a target object. The receiver is configured to receive the first optical waveform reflected off of the first target object and determine a distance to the first target object based on a time of flight from the transmitter to the first target object and back to the receiver.

  • Publication number: 20200248067
    Abstract: Electrically conductive proppants and methods for detecting, locating, and characterizing same are provided. The electrically conductive proppant can include a substantially uniform coating of an electrically conductive material having a thickness of at least 500 nm. The method can include injecting a hydraulic fluid into a wellbore extending into a subterranean formation at a rate and pressure sufficient to open a fracture therein, injecting into the fracture a fluid containing the electrically conductive proppant, electrically energizing the earth at or near the fracture, and measuring three dimensional (x, y, and z) components of electric and magnetic field responses at a surface of the earth or in an adjacent wellbore.

  • Patent number: 10463364
    Abstract: In repairing soft tissue with a bone anchoring instrument (such as reattaching a tendon of a torn rotator cuff), the bone anchoring instrument may be used to anchor the soft tissue to a region of bone. The anchors inserted into the underlying bone may have one or more lengths of suture or wire attached thereto which may be tensioned independently of one another to affix the soft tissue to the bone by having a selector mechanism selectively engage and disengage ratcheted tensioning wheels from one another. Suture loading mechanisms may be employed for passing suture lengths into and/or through the anchors prior to deployment into the bone where such mechanisms may employ suture snares which are configured to reconfigure from an expanded shape through which suture lengths may be easily passed to a low-profile shape which secures the suture lengths within the snare.

  • Publication number: 20190249536
    Abstract: Methods and systems for determining subterranean fracture closure are disclosed herein. The methods can include electrically energizing a casing of a wellbore that extends from a surface of the earth into a subterranean formation having a fracture that is at least partially filled with an electrically conductive proppant and measuring a first electric field response at the surface or in an adjacent wellbore at a first time interval to provide a first field measurement. The methods can also include measuring a second electric field response at the surface or in the adjacent wellbore at a second time interval to provide a second field measurement and determining an increase in closure pressure on the electrically conductive proppant from a difference between the first and second field measurements.
