Abstract: An audiovisual system with a shared image-processing procedure and a method for processing video therein are provided. The audiovisual system performs the image-processing procedure on a specific format video for optimizing images of the video. If a video format is not supported by the image-processing procedure in the audiovisual system, the video is converted to a video format supported by the audiovisual system. Various videos of different formats can accordingly share the same image-processing procedure. In the method, a first format conversion procedure is performed for converting a received second format video to a first format video that is supported by the image-processing procedure performed in the audiovisual system. The first format video can then be processed by the audiovisual system. It is determined if one more format conversion is required according to the format supported by a display at an output end of the audiovisual system.

Abstract: A method includes the steps of (a) adding an organosilicon compound containing methyl groups and a surfactant into water, mixing well and carrying out hydrolysis to get a mixed aqueous solution; (b) mixing the mixed aqueous solution with 0.1-0.2M ammonium hydroxide and a remaining percentage of an organic solvent, and stirring the mixture under nitrogen atmosphere for emulsion polymerization to get a water-in-oil (w/o) emulsion; and (c) removing the organic solvent and drying the w/o emulsion to get aerogel particles. Thereby the aerogel particles are produced by the present method without hydrophobic treatment and solvent exchange. Therefore the cost and time used for preparing the aerogel particles are saved.

Abstract: Aerogel particles and a method of making the same are revealed. The method includes the steps of (a) adding a siloxane compound containing methyl groups and a surfactant into water, mixing well and carrying out hydrolysis to get a mixed aqueous solution; (b) mixing the mixed aqueous solution with 0.1-0.2M ammonium hydroxide and a remaining percentage of an organic solvent, and stirring the mixture under nitrogen atmosphere for emulsion polymerization to get a water-in-oil (w/o) lotion; and (c) removing the organic solvent and drying the w/o lotion to get aerogel particles. Thereby the aerogel particles are produced by the present method without hydrophobic treatment and solvent exchange. Therefore the cost and time used for preparing the aerogel particles are saved.
