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.

Abstract: One disclosed aspect of the embodiments is a technique to package a dish having strips of dough, garnishes, pieces of meat, and broth. A main container has an inner wall and is configured to be sealed with a main lid. A secondary container has an outer wall and is configured to contain a first type of broth and sealed with a secondary lid. The secondary container is placed inside the main container such that the outer wall and the inner wall form a space accommodating the strips of dough and the pieces of meat. A separator is placed above the secondary container to hold the garnishes underneath the main lid.
