A forward-facing vision system for a vehicle includes a forward-facing camera disposed in a windshield electronics module attached at a windshield of the vehicle and viewing through the windshield. A control includes a processor that, responsive to processing of captured image data, detects taillights of leading vehicles during nighttime conditions and, responsive to processing of captured image data, detects lane markers on a road being traveled by the vehicle. The control, responsive to lane marker detection and a determination that the vehicle is drifting out of a traffic lane, may control a steering system of the vehicle to mitigate such drifting, with the steering system manually controllable by a driver of the vehicle irrespective of control by the control. The processor, based at least in part on detection of lane markers via processing of captured image data, determines curvature of the road being traveled by the vehicle.

Vision system for vehicle

A vehicular vision system includes a camera having a lens and a CMOS photosensor array having a plurality of photosensor elements. The camera is disposed at an interior portion of a vehicle equipped with the vehicular vision system. The camera one of (i) views exterior of the equipped vehicle through the windshield of the equipped vehicle and forward of the equipped vehicle and (ii) views from the windshield of the equipped vehicle into the interior cabin of the equipped vehicle. A control includes an image processor that processes image data captured by the photosensor array. The image processor processes captured image data to detect an object viewed by the camera. The photosensor array is operable at a plurality of exposure periods and at least one exposure period of the plurality of exposure periods is dynamically variable.

An interior rearview mirror system suitable for use in a vehicle includes an interior rearview mirror assembly having a mirror casing and a transflective reflective element. The transflective reflective element has an electrochromic active region, and a plurality of user input elements is disposed outside of the electrochromic active region and below the electrochromic active region. Each of the individual user input elements is a touch or proximity sensor. A plurality of display elements is disposed behind the transflective reflective element at the electrochromic active region, and each display element is selectively activated by activation of a respective user input element. Each of the individual display elements and its associated respective one of the individual user input elements are located local to one another such that a cognitive relationship between actuation by a user of a respective user input element and activation of its associated display element is established.

A video mirror system for a vehicle includes an interior rearview mirror assembly with an electrochromic reflective element having a front portion and a rear portion generally opposite the front portion. The reflective element has an electrochromic medium disposed between a first substrate and a second substrate and has a transflective third-surface mirror reflector that is at least 15 percent transmitting to visible light and that is at least 40 percent reflective to visible light. A video display is disposed to the rear of the reflective element and emits light when actuated that passes through the transflective mirror reflector. The video display is back lit by at least one light source, and the video display is operable to exhibit a display intensity as viewed by the driver of at least about 400 candelas per square meter when the interior rearview mirror assembly is mounted and is viewed in the vehicle.

A process for producing a curved polarizing sheet having a polycarbonate protective layer, which comprises laminating a polycarbonate film or sheet on both sides of a polarizing film comprising a high polymer film containing an orientated dichroic dye to prepare a polarizing laminate and forming the polarizing laminate so as to have a curved surface while heating at a temperature ranging from 120°C to a temperature higher than the glass transition temperature of the polycarbonate by 30°C and applying a force of 1.2 Kg/cm² or less to the polarizing laminate before the heating temperature reaches the glass transition temperature of the polycarbonate; and a product obtained thereby are disclosed. The curved polarizing sheet is free from optical strain and excellent in impact strength.

Hydrogen peroxide is produced commercially by the sequential hydrogenation and oxidation of anthraquinone (AQ) and tetrahydroanthraquinone (THAQ). The hydrogenation of AQ and THAQ on the Pd(111) surface is investigated with periodic density functional theory (DFT) calculations in this work. Dihydrogen is preferentially adsorbed on the top of a Pd atom, and the produced hydrogen atoms are on two neighboring 3-fold hollow fcc positions. The three benzene rings of AQ are located at bridge sites on the Pd(111) surface. The two carbonyl oxygen atoms of AQ and THAQ successively abstract the surface hydrogen atoms to produce anthrahydroquinone (AHQ) and tetrahydroanthrahydroquinone (THAHQ), respectively. The formation of unwanted byproducts, anthrone (AN), tetrahydroanthrone (THAN), oxanthrone (OAN), and tetrahydro-oxanthrone (THOAN), in the hydrogenation step of the AQ process is also studied to consider the suppression of these byproducts.
