Abstract: A transparent article is described herein that includes: a glass-ceramic substrate comprising first and second primary surfaces opposing one another and a crystallinity of at least 40% by weight; and an optical film structure disposed on the first primary surface. The optical film structure comprises a plurality of alternating high refractive index (RI) and low RI layers and a scratch-resistant layer. The article also exhibits an average photopic transmittance of greater than 80% and a maximum hardness of greater than 10 GPa, as measured by a Berkovich Hardness Test over an indentation depth range from about 100 nm to about 500 nm. The glass-ceramic substrate comprises an elastic modulus of greater than 85 GPa and a fracture toughness of greater than 0.8 MPa·?m. Further, the optical film structure exhibits a residual compressive stress of ?700 MPa and an elastic modulus of ?140 GPa.

Abstract: Surround-view monitoring of a trailer, including: monitoring a birds-eye view of an image of the trailer rendered in real-time to visually aid a driver of the trailer during driving and parking; determining whether at least one event has been detected by at least one sensor; storing at least one surround-view video file in a storage device when it is determined that the at least one event has been detected, wherein the at least one surround-view video file includes the birds-eye view of the image of the trailer rendered in real-time using a plurality of cameras positioned about the trailer.
