Patent number: 12134247Abstract: The use of camera-based safety systems is growing at a rapid rate in automobiles where they are used to provide lane departure warning, collision avoidance, adaptive cruise control and other functions. As the industry moves towards full autonomous capability, the number of cameras and the resolution are increasing. For proper operation, the cameras require a clear undistorted field of view. Keeping the camera area free of snow and ice has been a problem. A resistive heating circuit is typically used to keep the area clear. For rapid clearing the circuit needs to operate at a high-power level. Due to the temperature dependent index of refraction of the plastic interlayer, severe distortion can result from the non-isothermal heating resulting from the spacing of the circuit elements. The laminate of the invention reduces distortion by removing the interlayer in the camera field of view and replacing with a plastic having a more temperature stable index of refraction.Type: GrantFiled: March 20, 2019Date of Patent: November 5, 2024Assignee: AGP America S.A.Inventors: Mario Arturo Mannheim Astete, Laura Granados Caro

Patent number: 10807344Abstract: Thermal insulation structures include a polymer foam layer adhered to a multi-layer sheet having a non-cellular layer of a heat-resistant thermoplastic and a second non-cellular layer of a polylactide resin. The polylactide resin is a surprisingly good barrier to the diffusion of atmospheric gases into the foam layer and of blowing agents out of the foam layer. Accordingly, the diffusion of atmospheric gases and blowing agents is retarded substantially. This greatly reduces the loss of thermal insulation capacity of the structure due to the replacement of the blowing agent with atmospheric gases. The multi-layer sheet exhibits excellent thermal stability, even when the polylactide in the polylactide layer is highly amorphous.Type: GrantFiled: April 24, 2017Date of Patent: October 20, 2020Assignee: NatureWorks LLCInventors: Nemat Hossieny, Osei A.

Patent number: 9862865Abstract: Radiation pre-crosslinked polyolefin film and preparation method, and related encapsulation method and encapsulation assembly are provided. The radiation pre-crosslinked polyolefin film for encapsulation is prepared by preparing a film after mixing polyolefin raw materials together; using a radiation energy source to irradiate the film, wherein the radiation energy source directly stimulate a crosslinking reaction of the polyolefin raw materials; adjusting an irradiation dosage of the radiation energy source, such that a crosslinking degree of a pre-crosslinked portion of the film reaches about 3 % to about 95%; and adjusting the irradiation dosage of the radiation energy source, such that the pre-crosslinked portion of the film has a thickness of about 5% to about 100% by a total thickness of the film, wherein: that the pre-crosslinked portion has the thickness of about 100% by the total thickness of the film means the film is all pre-crosslinked.Type: GrantFiled: February 16, 2015Date of Patent: January 9, 2018Assignee: SHANGHAI HIUV NEW MATERIALS CO., LTD.Inventor: Min Li
