  • Patent number: 11634128
    Abstract: Methods and systems are provided for a vehicle towing a trailer within a lane of a roadway that include: reconstructing, via a processor onboard the vehicle, lane markings for the trailer using lane markers as sensed via camera data; transforming the reconstructed lane markings, using additional sensor data, to a perspective of the trailer; localizing the trailer within the transformed lane markers using historical camera lane marking information, articulated vehicle dynamics, hitch angle, and trailer dimensions, without needing to add additional trailer lane sensing cameras to the trailer; calculating a time to lane crossing (T-TTLC) value for the trailer and vehicle; generating candidate blended paths of the trailer and the vehicle with a centerline of the lane of the roadway; and controlling operation of the vehicle, the trailer, or both, via instructions provided by the processor to keep the vehicle, the trailer, or both within a lane of travel.

  • Patent number: 11523871
    Abstract: A system for adjusting an operating state of a medical electronic device is described. In an aspect, the system includes an optical tracking system configured to detect three or more tracking markers. The system also includes a processor coupled with the optical tracking system. The processor is programmed with instructions which, when executed, configure the processor to: configure an input command by assigning at least one operating state of the medical electronic device to a particular state of at least one of the tracking markers; after receiving a priming command, identify a present state of the tracking markers based on data from the optical tracking system; compare the present state with the particular state assigned to the operating state; and based on the comparison, determine that an input command has been received and adjust the operating state of the medical electronic device to the assigned operating state.

  • Patent number: 11416995
    Abstract: Methods and apparatuses for performing patient registration. 3D scan data from a 3D scanner, preoperative image data, first tracking data from a first tracking system, and second tracking data from a second tracking system are mapped to a common coordinate space. The 3D scan data and the first tracking data are mapped to each other using a transformation that is determined based on a calibration relating the 3D scan coordinate space and the tracking coordinate space. The 3D scan data and the preoperative image data are mapped to each other using a surface matching algorithm. The first tracking data and the second tracking data are mapped to each other based on tracking of the patient reference device.

  • Patent number: 11191595
    Abstract: A method for updating a patient registration during a medical procedure is disclosed. The medical procedure uses an optical navigation system for optically tracking a patient reference object in a real-world space. The method includes: acquiring a first set of image data depicting a region of interest on the patient while a first patient registration is intact; detecting that the first patient registration has been lost; obtaining a second set of image data depicting the region of interest; and applying a transform to data points of the first region to obtain data points for an updated patient registration, the transform obtained based on the first and second sets of image data.
