  • Patent number: 10737358
    Abstract: The metallurgical composition of a machine surface may be determined. Based on the composition of the surface layer and its substrate materials, a mixture of pure metal nanoparticles, each coated with a monomolecular organic layer adsorbed on its surface can be mixed with catalysts, reaction initiators, and/or other necessary ingredients for the repair action of the machine surface, depending on the specific machine, operational type, and/or the nature of the damage. The nanoparticles are applied to the machine surface, the organic monolayer wears away from the nanoparticles under shear stresses and the nanoparticles adhere to the machine surface to form a repair layer on the machine surface, thereby providing a repaired surface.

  • Patent number: 10708388
    Abstract: Methods, systems, and devices for defining an action node series at a database system are described. In some examples, the workflow may include one or more nodes are associated with an action. When executed, the workflow may produce an outcome based on the occurrence of an event or parameter associated with the one or more nodes. In some examples, the workflow may include one or more branch nodes. A branch node may include logic such that, when the workflow is executed, the logic selects a particular workflow path that includes its own specific nodes. The path may be selected based on the occurrence of an event or a value of one or more parameters. Thus, when a workflow including one or more branch nodes is executed, the outcome of the workflow may be based on the occurrence of the event or the value of the parameter.

  • Patent number: 10380516
    Abstract: In a crowd sourcing approach, responses to customer service inquiries are provided by routing a subset of the inquiries to an independent group of experts. The customer service inquiries are optionally routed to specific experts based on matches between identified subject matter of the inquiries and expertise of the experts. Embodiments include methods of classifying customer service inquiries, training a machine learning system, and/or processing customer service inquiries. Multiple experts may provide responses to a particular customer service inquiry, optionally within a single chat window.

  • Patent number: 10235639
    Abstract: In a crowd sourcing approach, responses to customer service inquiries are provided by routing the inquiries to an independent group of experts. Machine learning based systems are used in combination with contact center staff and/or the independent experts to resolve the customer service inquiries. The AI based systems can be configured to determine which of the customer service inquiries should be routed to the independent experts, and/or to generate content for inclusion in responses to the customer service inquiries. The machines systems are optionally trained based on scored responses to prior customer service inquiries. These scored responses can include content provided by a machine learning system and/or a human expert.

  • Patent number: 10102395
    Abstract: Systems and methods for facilitating users to create multi-faceted social media objects (e.g., text, images, videos, etc.) with one public facing front side and multiple secondary facets that have optional privacy controls are provided. Users can scroll down a feed and perform gestures on each social media object to transition them to flipsides to view optionally private content in an intuitive manner. Graphical animations for transitioning from the front side of the social media object to the secondary facets can be simultaneously viewed within the feed interface. This enables a user to create a publicly visible social media object and essentially hide a message on the flipside(s) for selected other users to access. The hidden message may be contextual to the public side.

  • Patent number: 9154748
    Abstract: The system to proctor an examination includes a first camera worn by the examination taking subject and directed to capture images in subject's field of vision. A second camera is positioned to record an image of the subject's face during the examination. A microphone captures sounds within the room, which are analyzed to detect speech utterances. The computer system is programmed to store captured images from said first camera. The computer is also programmed to issue prompting events instructing the subject to look in a direction specified by the computer at event intervals not disclosed to subject in advance and to index for analysis the captured images in association with indicia corresponding to the prompting events.

  • Publication number: 20150272653
    Abstract: Thermal therapy ablation detection uses medical diagnostic ultrasound. Since acoustically measured information becomes unreliable for temperature estimation at a temperature close the time at which treatment is complete, the information is instead or additionally used to detect a tissue condition indicating sufficient treatment, such as detecting cell death. Using multiple different types of parameters as input and/or a machine-learnt classifier, the completion of treatment from a tissue alteration perspective is detected using the transition that makes temperature estimation less reliable.
