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: The patent presents a new method of damping for laser activation systems including five steps: Step 1: Locating, clamping the batteries, PCB; Step 2: Receiving hammering force; Step 3: Damping for batteries; Step 4: Damping for PCB; Step 5: Sliding electrical contact drive. This damping method has outstanding advantages in vibration suppression in different frequency ranges and amplitudes, along with applied damping according to the requirements and characteristics of each part. As a result, the two-level damping method improves stability and longevity of the laser activation system.
