Title: Xu Wang: Innovator in Polyimide Precursors and Target Positioning Technologies
Introduction
Xu Wang is a notable inventor based in Jinan, China. He has made significant contributions to the field of materials science and technology, particularly in the development of innovative polyimide precursors and methods for precise target positioning.
Latest Patents
Xu Wang holds 3 patents that showcase his inventive prowess. His latest patents include a self-sensitizing negative polyimide precursor and a method for preparing the same. This invention utilizes 4,4'-dinitro-1,1′-biphenyl-2,2′-dicarboxylic acid as a starting material, which undergoes an acylation reaction with thionyl chloride to produce compound 1. This compound is then esterified with 2-hydroxyethyl methacrylate to yield compound 2. The nitro groups of compound 2 are reduced to amino groups, leading to the formation of an intermediate for the self-sensitizing negative polyimide precursor. The unique properties of this precursor allow it to act as a photoinitiator under ultraviolet irradiation, enhancing the exposure sensitivity of the resin.
Another significant patent by Xu Wang is a method and system for positioning a moving target based on camera pitch. This invention involves obtaining a vehicle trajectory from a video and performing coordinate conversion. The method includes positioning correction using an error correction technique, which factors in the camera height and pitch to achieve high-precision positioning of a moving target.
