Patent number: 12151459Abstract: Multiple layer interlayers having enhanced optical and acoustic properties are provided, along with methods of making and using the same. Interlayers as described herein may include at least two outer skin layers and an inner core layer, with one of the outer skin layers having a different thickness than the other at one or more locations along the interlayer. The multi-layer interlayer may also exhibit acoustic properties and, in some cases, may have an overall wedged thickness profile. Additionally, in some aspects, interlayers and laminates formed therefrom may also provide reduced infrared energy transmission, without sacrificing acoustic and/or optical performance.Type: GrantFiled: December 17, 2020Date of Patent: November 26, 2024Assignee: Solutia Inc.Inventors: Wenjie Chen, John Joseph D'Errico, Lora Lee Spangler, Gary Matis, Yalda Farhoudi, Bruce Edward Wade

Publication number: 20240239084Abstract: Windshields are disclosed herein having an optical path, that include an inner rigid substrate, optically adjacent a first wedge polymer layer, that serves to reflect a primary image. A reflective layer is also provided, positioned in the optical path between the first wedge polymer layer and a second wedge polymer layer. The windshields are further provided with an outer rigid substrate, optically adjacent the second wedge polymer layer. The first wedge polymer layer causes visible light reflected from the reflective layer to overlap the primary image, and the second wedge polymer layer causes visible light reflected from an outer face of the outer rigid substrate to overlap the primary image.Type: ApplicationFiled: June 23, 2022Publication date: July 18, 2024Applicant: SOLUTIA INC.Inventors: STEVEN V. HALDEMAN, LORA LEE SPANGLER, FRANCOIS ANDRE KORAN, JEFFREY B. HURLBUT

Publication number: 20170285339Abstract: A tapered interlayer and windshield employing the same are provided. Unlike conventional windshields, which are optimized to reduce ghost images for a single driver height, the windshields of the present invention may exhibit reduced ghosting for drivers of multiple heights, including very tall or very short drivers, while also providing desirable image clarity for average-height drivers. Windshields as described herein may be used in a variety of applications, including automotive, aircraft, marine, and recreational vehicles that employ HUD projection systems.Type: ApplicationFiled: February 23, 2017Publication date: October 5, 2017Applicant: SOLUTIA INC.Inventors: LORA LEE SPANGLER, JEFFREY B.
