Abstract:
A method for synthesizing 4,4-dihalogen-2-(dialkylamino)methylene-3-oxy-alkylbutyrate and its derivatives has acts of: (a) providing N,N-dialkylamino-alkyl-acrylate in a reaction vessel; (b) adding organic alkali, organic solvent and multiple molecular sieves into the reaction vessel; (c) mixing N,N-dialkylamino-alkyl-acrylate, the organic alkali, the organic solvent and the molecular sieves; and (d) adding 2,2-dihalogen-acetyl-chloride into the reaction vessel and allowing a synthetic reaction of 2,2-dihalogen-acetyl-chloride and N,N-dialkylamino-alkyl-acrylate to obtain 4,4-dihalogen-2-(dialkylamino)methylene-3-oxy-alkylbutyrate. The molecular sieves are able to remove water efficiently to prevent materials in the reaction vessel from undergoing side reactions or changing chemical properties. Furthermore, the molecular sieves are able to adsorb chloride to avoid polymerization reactions for improved yield.
Abstract:
Generating a high dynamic range image includes obtaining a maximum luminance and a minimum luminance of a scene to be captured, setting a first range of exposure values and a second range of exposure values according to the maximum luminance and the minimum luminance, capturing a first image of the scene according to the first range of exposure values and a second image of the scene according to the second range of exposure values, and superposing the images by compositing luminance information of pixels in corresponding locations of the images according to a tone mapping technique.
Abstract:
An axially symmetrical molded glass lens has a central longitudinal axis, a lens surface, an annular intermediate area and a mounting flange area. The lens surface is axially symmetric around the central longitudinal axis and is curved. The annular intermediate area is curved and axially symmetric, is formed around the lens surface and has a radius of curvature having a continuously vary modulus that decreases as the radius of curvature approaches the annular intermediate area. The mounting flange area is formed around and connects smoothly to the annular intermediate area. The axially symmetrical molded glass lens has fine precision, a high production rate and a low cost.

Abstract:
A flat panel display includes a plastic rear cover, a supporting frame, a liquid crystal display (LCD) module, a light bar and a front cover. The plastic rear cover constructs a rear half portion of an appearance of the flat panel display. The supporting frame is connected to the plastic rear cover. The LCD module is connected to the supporting frame. The light bar is disposed aside the LCD module. The front cover is connected to the plastic rear cover, constructs a front half portion of the appearance of the flat panel display, and has an opening to expose the LCD module.
Abstract:
An optical assembly includes a light source for generating and emitting light, a light guide plate, and a light transmissive plate. The light transmissive plate is disposed above the light guide plate and has a plurality of asymmetric V-shaped structures on a bottom surface thereof. The V-shaped structures may divert the light emitted from an optical element to exit at a collimation angle, thereby enhancing a light utilization, reducing loss of the light, and facilitating the enhancement of a positive gray level. Further, the optical assembly has a simple structure and a low cost.
