  • 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.

  • Publication number: 20210210841
    Abstract: A method for calibrating an antenna includes receiving a plurality of signals transmitted from an antenna on a spacecraft. The antenna includes a plurality of phase array elements. The method also includes determining a phase tilt of the phase array elements based at least partially upon the signals. The method also includes removing a first portion from the determined phase tilt. The first portion is caused by a first location of the spacecraft, a first attitude of the spacecraft, or both. The method also includes estimating the phase tilt of the phase array elements after the first portion is removed. The method also includes generating a reference tilt matrix for the phase array elements. The method also includes comparing the estimated phase tilt to the reference tilt matrix. The method also includes determining a pointing error of the antenna based at least partially upon the comparison.

  • Patent number: 10005190
    Abstract: An apparatus including a robot arm comprising a wrist, and an end effector. The wrist includes a frame member. The frame member includes a first material having a first coefficient of thermal expansion. The end effector is connected to the wrist at a connection. The end effector is configured to support a substrate thereon. The end effector includes a first member and a second member. At least one of the first and second members has a different second material with a different second coefficient of thermal expansion. The connection includes the first and second members being stationarily attached to each other with a portion of the frame member sandwiched therebetween.
