  • Patent number: 11872774
    Abstract: An apparatus for applying individual tapes in layers onto a substrate includes a plurality of reels, applicators, and a guide member. A first reel holds a first tape and a second reel holds a second tape. A first applicator includes a first pressure surface that receives the first tape from the first reel and presses the first tape in a direction toward the substrate to apply the first tape to the substrate. The second applicator includes a second pressure surface that receives the second tape from the second reel. The second pressure surface is aligned to dispense the second tape over a section of the first tape applied to the substrate and to press the second tape toward the substrate to apply the second tape over the first tape. The guide member is disposed between the reels and the applicators and aligns the first and second tapes during application.

  • Patent number: 11662208
    Abstract: Dead reckoning correction utilizing patterned light projection is provided herein. An example method can include navigating a drone along a pattern using dead reckoning, the pattern having a plurality of lines, detecting one of the plurality of lines using an optical sensor of the drone, determining when a line of travel of the drone is not aligned with the one of the plurality of lines, and realigning the line of travel of the drone so as to be aligned with the one of the plurality of lines to compensate for drift that occurs during navigation using dead reckoning.

  • Patent number: 11608016
    Abstract: Devices, systems, and methods for management of electrical resources for electric vehicles. A method may include receiving, by a vehicle, sensor data indicative of a first luminosity of a location, and determining that the first luminosity of the location exceeds a luminosity threshold. The method may include determining, based on the first luminosity exceeding the luminosity threshold, a second luminosity to apply to lights of the vehicle while the vehicle is at the location, the second luminosity greater than zero. The method may include applying the second luminosity to the lights while the vehicle is at the location.

  • Patent number: 11592468
    Abstract: A system for testing a plurality of electrical circuits includes a first remote cooperative testing device including a testing component and a first transceiver and a second remote cooperative testing device including a conductive component and a second transceiver. In response to receiving instructions from a remote computing device, the first remote cooperative testing device locates a first electrical circuit and a second electrical circuit and selectively positions the testing component to electrically couple a first portion of the first electrical circuit to a first portion of the second electrical circuit at a first node, and the second remote cooperative testing device selectively positions the conductive component to electrically couple a second portion of the first electrical circuit to a second portion of the second electrical circuit at a second node, thereby forming a testing circuit between the first node and the second node.

  • Publication number: 20230044574
    Abstract: Disclosed herein are methods for training and deploying a predictive model for generating a prediction, e.g., patient eligibility for a CAR-T therapy. Datasets, such as open healthcare claims datasets, may be missing data. Missing data may hamper the ability to generate sufficient information needed for training a predictive model. Methods include leveraging comprehensive datasets, such as closed claims datasets, to create training examples for input into a machine learning algorithm. In various embodiments, the comprehensive dataset is modified to simulate the data missingness in the target dataset; then, the modified dataset is paired with the ground truth label derived from the comprehensive dataset to create training examples. In various embodiments, a comprehensive dataset is paired with a target dataset to create training examples. After training a predictive model on such examples, the model can be deployed to make predictions in the target dataset even in light of missing data.

  • Patent number: 11535256
    Abstract: Chionophobia intervention systems and methods are disclosed herein. An example method includes detecting snowfall from a vehicle sensor of a vehicle or a service provider, displaying a prompt on a human machine interface (HMI) to query a user regarding additional assistance in response to the detection of the snowfall, activating a first stage response after detecting the snowfall, determining when the first stage response is insufficient based on feedback received from the user, and activating a second stage response when the feedback received from the user indicates that the first stage response is insufficient.
