  • METHOD FOR DETERMINING POSITION OF A LASER POINT APPLIED IN A FIREARM TRAINING SIMULATION SYSTEM USING INFRARED LASERS
    Publication number: 20240068783
    Abstract: A method to detect, identify and determine the position of laser points from infrared laser emitters in a firearm training simulation system. The method consists of two steps. This first step combines some common tools such as a camera with a filter switcher and edge and corner detecting algorithms in image processing to provide a fast automatic screen calibrating method. The second step is to detect laser point objects in each frame continuously captured by the camera, and then further process these objects to identify laser shots, filter out noisy objects, and eventually detect simulated shots from different laser emitters and determine the final mapped position of the shot.

  • Preparation process for ferrierrite zeolite and its uses as an isomerization catalyst of linear olefin in isoolefin or as a hydrocracking and hydroisomerization paraffin catalyst
    Patent number: 6136289
    Abstract: A process of preparing a ferrierite-type zeolite, with high crystallinity rate and having a anhydrous stage composition expressed by the formula M.sub.x (AlO.sub.2).sub.x (SiO.sub.2).sub.y, M being a cation of an alkaline metal such as Na or K, or a mix of both. The process contains a gel-producing step, by addition of boric acid to an aqueous aluminum-sulfate solution mixed with a aqueous solution containing oxides of Na and/or K and of Si, without the use of a structural agent. The invention also pertains to any zeolite obtained by this process, and its uses.
