  • Patent number: 11158427
    Abstract: According to an embodiment of the present invention, a system analyzes a collection of medical documents to identify within document content risk factors of medical conditions associated with corresponding activities. A processor in the system maps the identified risk factors of the activities to one or more medical tests for the associated medical conditions, and analyzes a medical record and social media communications of a patient to determine participation of the patient in one or more of the corresponding activities. The processor determines the one or more medical tests to conduct from the mapping based on the risk factors associated with the determined activities of the patient. Embodiments of the present invention further include a method and computer program product for analyzing patient activity to conduct appropriate medical tests in substantially the same manner described above.

  • Patent number: 10986087
    Abstract: A method for authenticating a user is presented. Responsive to a request for access to a computer resource, a computer system prompts the user making the request to access the computer resource to perform a new motion in an environment in which the user is monitored by a sensor system. Detected biometric data in the new motion performed by the user is identified by the computer system. A determination is made as to whether the user performing the new motion is an authenticated user based on comparing the detected biometric data with stored biometric data for a prior motion performed by the authenticated user. The computer system provides access to the computer resource when the user is identified as the authenticated user.

  • Patent number: 10915740
    Abstract: A facial expression feedback system for providing real-time feedback on how closely a user matches his or her facial expression to a target expression is presented. The facial expression feedback system receives sensor data captured by a set of sensors. The facial expression feedback system evaluates the captured sensor data to generate a set of confidence scores with respect to a target facial expression. The system presents the feedback by modifying a multimedia presentation based on the generated set of confidence scores.

  • Patent number: 10803246
    Abstract: A method, system, and/or computer program product for identifying and replacing a deficient component in a product. One or more processors deconstruct a text product review into multiple n-grams, where each of the multiple n-grams is a review of a particular component from components of a product. The processor(s) generate a component numeric rating value (CNRV) for each of the multiple n-grams, where the CNRV is based on an analysis of each of the multiple n-grams. The processor(s) identify a deficient component of the product. The processor(s) identify a cause of the deficiency in the deficient component and identify a replacement component that does not cause the deficiency in the deficient component. The processor(s) direct a manufacturing device that manufactures the product to replace the deficient component with the replacement component.

  • Patent number: 10732705
    Abstract: A system and method to perform incremental adaptive modification of a virtual reality image involve obtaining sensor measurements from sensors coupled to an individual who is performing a task while viewing the virtual reality image. The method includes generating a true model of the individual from the sensor measurements, comparing the true model with an expert model obtained from another individual performing the task, and developing a lesson plan based on determining a difference between the true model and the expert model. The developing the lesson plan includes determining a gradient of intermediate models within the difference. A different one of the intermediate models is included iteratively along the gradient from the true model to the expert model in the virtual reality image.
