Patent number: 11912199Abstract: A vehicular trailer hitching assist system includes a camera disposed at a rear portion of a vehicle and viewing at least rearward of the vehicle. During a reversing maneuver of the vehicle toward a trailer that is spaced from the vehicle at a distance from the vehicle, the camera views at least a portion of a front profile of the trailer. An electronic control unit (ECU) includes an image processor operable to process image data captured by the camera. The vehicular trailer hitching assist system, via image processing at the ECU of image data captured by the camera during the reversing maneuver of the vehicle toward the trailer, determines a plurality of landmarks corresponding to the front profile of the trailer. Based at least in part on the determined plurality of landmarks, the vehicular trailer hitching assist system determines location of a trailer coupler of the trailer.Type: GrantFiled: March 27, 2023Date of Patent: February 27, 2024Assignee: Magna Electronics Inc.Inventors: Akbar Assa, Shweta Suresh Daga, Brijendra Kumar Bharti, Guruprasad Mani Iyer Shankaranarayanan, Jyothi P.

Patent number: 10784455Abstract: A barrier film including a substrate, a base (co)polymer layer applied on a major surface of the substrate, an oxide layer applied on the base (co)polymer layer, and a protective (co)polymer layer applied on the oxide layer. The protective (co)polymer layer is formed as the reaction product of a first (meth)acryloyl compound and a (meth)acryl-silane compound derived from a Michael reaction between a second (meth)acryloyl compound and an aminosilane. The first and second (meth)acryloyl compounds may be the same. In some embodiments, a multiplicity of alternating layers of the oxide layer and the protective (co)polymer layer may be used. An oxide layer can be applied over the top protective (co)polymer layer. The barrier films provide, in some embodiments, enhanced resistance to moisture and improved peel strength adhesion of the protective (co)polymer layer(s) to the underlying layers. A process of making, and methods of using the barrier film are also described.Type: GrantFiled: January 15, 2018Date of Patent: September 22, 2020Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Thomas P.
