Abstract: Disclosed herein is a method comprising capturing an image of a grating formed on a surface of a brightness enhancing display film; measuring a displacement ?d of a fringe from the image of the grating; and determining a slope of a deviation from flatness of the brightness enhancing display film from the displacement ?d by using the equation (I) ? ? ? ? d ? ( y , ? 2 ) = 2 ? y ? ? ? sin ? ( ? 1 + ? 3 - 2 ? ? 2 ) [ tan ? ( ? 1 + ? 3 - ? 2 - 90 ) tan ? ( 90 - ? 2 ) + tan ? ( ? 1 + ? 3 - ? 2 - 90 ) ] ( I ) wherein y represents a distance along the brightness enhancing display film that represents a location of the deviation from flatness; ?1 is a light box angle; ?2 is the slope of the deviation from flatness in the brightness enhancing display film; and ?3 is a camera angle.

Abstract: A projector (20) projects a structured light pattern (46) along a first optical axis (44) onto a surface (80). A viewer (50) attached to the projector (20) receives a reflection of the structured light pattern (46) from the surface (80) along a second optical axis (54), and digitizes a two-dimensional snapshot. The optical axes (44, 54) are non-parallel, and they meet within a common field of view of the projector (20) and the viewer (50). A computer (61) interfaced to the viewer (50) receives the digitized snapshot, and analyzes it to mathematically model the surface for display and inspection. The projector and attached viewer are designed as a hand-held unit with a hand grip (66) and a trigger button (68) to trigger a snapshot. A guide tip (70) on the unit extends beside the two optical axes (44, 54) to the common field of view to position the hand-held unit.

Abstract: A synthesis method of alanyl-glutamine includes the steps of: The N-terminal protected alanine reacts with triphenylphosphine and hexachloroethane in organic solvent to form active ester, the active ester reacts with glutamine in a solution mixture containing organic solvent and aqueous solution of inorganic base, the resultant mixture is acidified with inorganic acid, and then the N-terminal protecting group is removed. In this method, the raw materials are cheap, the synthesis technique is simple, no disposals of separation and purification are needed, the product is easy to be separated and purified, the toxicities of all the reagents used in the course of production are minimal, it is advantageous to environment protection.

Abstract: An optical device comprised of multiple substrates with complimentary functions. The substrates are joined by structures that are integrated into the substrate surfaces. The joining structures are alternatively used to provide a spacer between the optical surface and other system components.

Abstract: Provided is a process for producing a fatty acid alkylester through a transesterification of triglyceride contained in a fat and oil by causing the fat and oil and an alcohol to react with each other. In this process, the reaction is performed in an atmosphere in which the alcohol is in super-critical state in the absence of a metal alkali catalyst and an acid catalyst. This makes it possible to eliminate a pre-treatment process for esterifying free fatty acids contained in the fat and oil and, in addition, to eliminate or simplify recovering and refining processes of the reaction product by suppressing the by-production of a fatty acid soap.
