  • Vehicle with polarimetric image normalization logic
    Patent number: 12291231
    Abstract: A system for a host vehicle operating on a road surface includes a polarimetric camera, a global positioning system (“GPS”) receiver, a compass, and an electronic control unit (“ECU”). The camera collects polarimetric image data of a drive scene, including a potential driving path on the road surface. The ECU receives the polarimetric image data, estimates the Sun location using the GPS receiver and compass, and computes an ideal representation of the road surface using the Sun location. The ECU normalizes the polarimetric image data such that the road surface has a normalized representation in the drive scene, i.e., an angle of linear polarization (“AoLP”) and degree of linear polarization (“DoLP”) equal predetermined fixed values. The ECU executes a control action using the normalized representation.

  • Automated detection of specular reflecting road surfaces using polarimetric image data
    Patent number: 12291232
    Abstract: A detection system for a host vehicle includes a camera, global positioning system (“GPS”) receiver, compass, and electronic control unit (“ECU”). The camera collects polarimetric image data forming an imaged drive scene inclusive of a road surface illuminated by the Sun. The GPS receiver outputs a present location of the vehicle as a date-and-time-stamped coordinate set. The compass provides a directional heading of the vehicle. The ECU determines the Sun's location relative to the vehicle and camera using an input data set, including the present location and directional heading. The ECU also detects a specular reflecting area or areas on the road surface using the polarimetric image data and Sun's location, with the specular reflecting area(s) forming an output data set. The ECU then executes a control action aboard the host vehicle in response to the output data set.

  • Ramp lock extractor tools, systems, and methods for disassembling mutlipart component bodies
    Patent number: 12280477
    Abstract: Presented are ramp lock extractor (RLE) lift tools for disassembling multipart assemblies, methods for making/using such lift tools, and vehicles with multipart assembly modules disassembled by such lift tools. A method of separating first and second component bodies joined together via an adhesive includes aligning an RLE lift tool with an RLE key slot that extends through the first component body. The lift tool includes multiple ramp pins projecting outward from lateral sides of a tool stem. The key slot includes multiple helical ramps located on lateral sides of a through-hole. The lift tool inserts into the key slot until a distal tip of the tool stem abuts the second component body. The lift tool rotates within the key slot to slide the ramp pins along the helical ramps, causing the tool stem's distal tip to press against the second component body and thereby separate the two component bodies.
