  • FIBER NOISE CANCELLATION
    Publication number: 20230350130
    Abstract: A system and method for delivering stable light to a remote location are provided. The method includes splitting a laser beam generated by a laser into a reference beam and a delivery beam. The delivery beam is coupled into an optical fiber for delivery to the remote location. A reflected portion of the delivery beam comes back as a reflected delivery beam from the remote location through the optical fiber. An interference beam is generated by combining the reference beam and the reflected delivery beam. A phase difference between the reference beam and the reflected delivery beam is detected in order to adjust a phase of the laser beam based on the phase difference to reverse a phase shift of the delivery beam induced by noise added to the delivery beam while the delivery beam is transmitted through the optical fiber.

  • System and method for determining subject conditions in mobile health clinical trials
    Patent number: 11804287
    Abstract: A method for calculating a subject's state or condition comprises integrating data that are captured from multiple sources, storing the integrated data in a first database, calculating time intervals in which to collect an optimal amount of data to predict the subject state, developing a predictive model using a recorded diary or electronic data capture information, testing the model against a portion of the captured data, and applying the predictive model to new data from other sources. The predictive model may determine a subject state that may be a digital bio-marker for a disease condition. A system for predicting subject state is also disclosed.

  • Efficient caching and data access to a remote data lake in a large scale data processing environment
    Patent number: 11797447
    Abstract: Embodiments described herein are generally directed to caching and data access improvements in a large scale data processing environment. According to an example, an agent running on a first worker node of a cluster receives a read request from a task. The worker node of the cluster to which the data at issue is mapped is identified. When the first worker node is the identified worker node, it is determined whether its cache contains the data; if so, the data is fetched from a remote data lake and the agent locally caches the data; otherwise, when the identified worker node is another worker node of the compute cluster, the data is fetched from a remote agent of that worker node. The agent responds to the read request with cached data, data returned by the remote data lake, or data returned by the remote data agent as the case may be.

    Publication number: 20230316726
    Abstract: A system and method for training an AI model. A recorded video is divided into video frames that are input and read by a processor that identifies objects in the video frames using the object’s latent characteristics. The processor further classifies an event based on the identified object, the latent characteristics, and surrounding factors at the time the object is identified. Video frames are annotated based on the identified object and classified event. A user’s responses to annotated frames are tracked and the latent characteristics are adjusted based on the user’s responses.
